Black Limestone Floor Renovation in Lancaster

Clean and Seal of a Black Limestone Kitchen Floor in Lancaster

This customer from Lancaster contacted us about cleaning and sealing what they thought was a Blue Slate kitchen floor. Having spoke to them over the phone I arranged to pop over and survey the floor to get a better understanding of the work that needed to be done. Lancaster is a few miles South of our base in Carnforth and I’m always passing though.

Having visited the property I was able to confirm that the floor wasn’t Slate but Black Limestone which is notoriously high maintenance due to its acid sensitivity. I mentioned this and they were quite surprised as it had only been laid a few years earlier and it was sold as Black Slate. The two materials do look identical, but if you drop a small amount of something acidic on Black Limestone the stone fizzes and turns Grey and White.

The big problem with Black Limestone is unlike Slate its very porous, this is why you see Slate being used for roof tiling and is still popular covering even to this day. Also, its very acid sensitive, so even Tea, Coffee, Juice, or Wine can mark it, so although popular in gardens it’s certainly not a stone we would recommend for use in a kitchen or bathroom.
Another problem you have is Black Limestone contains natural oils and it’s the oil that gives it that beautiful black colour. Once the oil is washed out of the stone over time or through the use of acidic cleaning products it leaves the stone looking grey and unattractive. This can be resolved however using an oil-based sealer but it is more expensive than a regular stone sealer.

This stone is still workable though, so it’s not all bad news, with the right treatment it can look as good as the day it was laid (if not better) so I came up with a renovation plan that would do exactly that. They were happy to have the work done so we scheduled a date for the work to start.

Cleaning a Black Slate Floor Tiled Kitchen Floor

We find the best way to renovate floors like this is to use coarse diamond pads that can cut into the stone remove any surface damage, contaminates, old sealers and generally leave the stone very clean.

With this floor I started with a very coarse 50-grit DRB pad which is run several times over each stone using only water to lubricate the process. The process generates a lot of soiling and loose sediment that has to be rinsed off the floor with water and then extracted with a wet vacuum. Once this is done the process is repeated with a 100 and then 200-grit pad which together effectively re-hone the stone and remove any scratches caused by the previous pad. A dilution of Remove and Go was also used with the 200-grit pad to ensure the tiles were clean and any remaining sealer not caught by the pads had been removed.

The last step on the first day was to re-point the stone tiles where needed to remove failed and crumbling mortar. This was then left to set hard overnight so we could continue with the renovation the next day.

On day two we followed up the renovation of the stone by moving onto finer Burnishing pads starting with a 400-grit diamond pad applied in the same way and rinsing and extracting afterwards. This was followed by the application of an 800 and then 1500-grit pad to further refine and improve the stone.

The following day the Black Limestone was sealed with a coat of Tile Doctor X-Tra seal which is the Oil based sealer I mentioned earlier. It brings out the true colour of this stone and the seal leaves a sheen appearance to give a very appealing finish. We find one coat is usually enough for this sealer as it’s a lot thicker that other sealers.

Before leaving I talked through aftercare cleaning with two buckets and the importance of using a pH Neutral cleaning product. We recommend avoiding steam cleaners and not to use cheap bleach or acidic cleaning products which can damage the sealer with repeated use.

Black Caithness Slate After Renovation Gressingham

Caithness Black Slate Floor Restored with Milling Pads in Gressingham

The photos above detail the restoration of Black Caithness Slate pavers at an old cottage in the village of Gressingham on the outskirts of Lancaster. The building was in the process of being completely overhauled and the floor was next on the long renovation to do list.

Black Caithness Slate Pavers Before Cleaning

Caithness Slate from the northern tip of Scotland and is known for its durability and strength however the years had certainly not been kind to this floor and it was in a very bad state.

To restore the appearance of the slate I recommended milling the floor with a set of very coarse pads that would remove a thin layer of stone off the top of the paving slab to reveal new stone underneath. The pointing was also cracked and loose in places so that would also need chopping out and replacing. After milling the stone would also be smoother and once sealed much easier to maintain going forward.

I estimated the process would take four days to complete. Happy to go ahead with the quote a date was booked for the work to start.

Resurfacing Caithness Black Slate

On the first two days there were two of us involved to get through milling the stone which is hard work. We used a set of milling pads applied to a weighted floor machine to cut through the stones surface using water for lubrication. This generates a lot of stone dust so a lot of rinsing and extracting needs to happen to remove it.

Milling carried on into day two but by the end we had started knocking out the old pointing which had already failed and wasn’t too difficult to remove. It was one big room with a partition at one end, the building itself was built in the 1870s or at least that’s as much information as the client could find as it was bought in an auction.

Black Caithness Slate Pavers During Renovation

Due to its age, it had no water or electricity, so we had to work off generators whilst a rudimentary system supplied the water. This was not the easiest job for us as the generators were proving difficult to work with as the relays would overload and cut off the power; this happened more than a dozen times just in the first day alone, but we like a challenge.

As you will see from the pictures the stone flagstones were transformed. This was not a simple clean and seal job, this is milling back the surface using various diamond grits a heavy weighted buffing machine and patience, and some water. Using a wet system, the milling system won’t leave a house full of dust and the diamond grinding leaves the stone much smoother and a lot cleaner which makes it a lot easier to clean and maintain in the future.

Once the milling was complete and the new flexible breathable pointing was applied for which we like to use a product called VDW 800. We then called back the next day and finished the clean, the floor area was left for another day to dry.

Once dry, the floor was then sealing using a single coat of Tile Doctor X-Tra seal which is oil-based sealer that really brings out the colour of the Black slate. Additionally, this sealer is fully breathable so it will cope with the damp conditions you find with old floors that don’t have a damp proof membrane and so won’t peel off after a few weeks.

The client was very happy with the transformation and final finish and invited us back to cover more work in the outbuildings which eventually will join onto the main house. For aftercare cleaning I recommended Tile Doctor Neutral Clean which is an effective tile and grout cleaner that won’t upset the sealer.

Copper Slate Tiled Kitchen Floor Cleaned Sealed in Ribchester

Renovating Copper Slate Tiles with a Semi Riven Finish in Ribchester

1 Comment / Grout Cleaning, Preston Tile Cleaning, Slate Tile Cleaning, Work by Category, Work by Location, Work History / Russell Taylor

This Copper Slate tiled floor at a property in the Ribble Valley village of Ribchester had been sealed just twelve months before by another company who used a topical acrylic sealer as the client wanted a shiny finish. However, this was a bad choice for a semi-riven tile and exacerbated by the fact that the client had three large dogs. The topical sealer just couldn’t cope and the shine on the Slate faded in a few months.

Semi Riven Copper Slate Before Cleaning Ribchester

After discussing the problem, I suggested stripping off what was left of the topical seal and then re sealing with a sturdier impregnating sealer. I recommended a product called Tile Doctor X-Tra seal which is a premium product that improves colour and is very durable so much so it can also be used externally. Since releasing this product last year it has proved to be very popular and has proven to be the answer in numerous tricky situations. It also adds a lustre and patina to the stone. The client was happy to go ahead with my quote.

Cleaning a Semi Riven Copper Slate Tiled Kitchen Floor

My first concern when dealing with a floor situated in a kitchen is to prevent water being absorbed by the kitchen base units and plinths. Normally the plinths can be removed but if not, the solution is to run a bead of silicone around the area of concern. MDF is easily blown by moisture, and it doesn’t take us long to add so it’s well worth doing.

The cleaning started with the application of a strong dilution of Tile Doctor Pro-Clean which was scrubbed into the floor to remove the old sealer. On this occasion it was scrubbed in using a 200-grit milling pad fitted to a rotary machine. As well as stripping off the old sealer this action deep cleans the tile and grout. A lot of soil is released during the process, and this is brushed and rinsed away with clean water and extracted using a wet vacuum.

The next step was to give the floor an Acid Rinse using a product called Tile Doctor Grout Clean-up, this not only cleans the grout but also neutralised the pH of the floor after cleaning with The Tile Doctor Pro-Clean which is an alkaline product.

An acid wash removes grout smears, unwanted mineral deposits and roughens the stone at a microscopic level to provide a better bond for the sealer. You must be careful what you use it on, and we wouldn’t recommend it for use on acid sensitive materials such as Limestone, Marble, or Travertine. Grout Clean-up is however safe to use on Slate, but I wouldn’t leave it on for a long period of time.

After another rinse with water the wet vacuum was deployed again to remove as much moisture from the floor as possible. The floor was then left to dry out fully overnight.

Sealing a Semi Riven Copper Slate Kitchen Floor

The next day after confirming the floor was dry, work started with the application of what would be two coats of Tile Doctor X-Tra seal. X-Tra seal is an impregnating sealer that soaks into the pores of the Slate ensuring dirt cannot reside there.

Semi Riven Copper Slate After Cleaning Ribchester

I would be the first to admit that a topical sealer would have resulted in a shiner finish but clearly this was not a practical choice when you have 3 big dogs who will run around the floor and tear at the sealer with their claws. Topical sealers as the name suggest sit on the surface and are simply not a very practical option for this situation.

Once completed the Copper colour in the Slate was really enhanced, the grout looked much cleaner and overall, the floor looked great; more importantly the client was very happy with the work we had carried out.

For the cleaning of sealed Slate tiles, I recommend the use of Tile Doctor Neutral Clean which is pH neutral and gentle enough for regularly use. Its also provided in concentrated form so a small amount goes a long way. Many of the floor cleaning products you find in supermarkets are bleach based and far too strong for use on a sealed tile resulting in premature damage to the sealer. I forgot to ask what they had been using to clean the floor previously, but this may also have been a factor in why the previous sealer only lasted a few months.

Riven Green Slate Kitchen Floor Renovation Leyland

Old Riven Green Slate Kitchen Floor Renovated in Leyland

1 Comment / Leyland Tile Cleaning, Slate Tile Cleaning, Work by Category, Work by Location, Work History / Russell Taylor

This is an old Riven Green Slate floor in the kitchen of a property in Leyland that dates to when the house was built around 150 years ago. It was looking very worn indeed and the cement pointing was falling out in several areas. The client requested a site visit so we could provide a quote for the renovation.

Riven Green Slate Before Cleaning in Leyland

On inspection I could see the floor was in desperate need of a deep clean, repairs to the pointing and then sealing to add protection going forward. Having worked on the renovation of similar stone floors I was confident we could improve it significantly and with a new sealer applied it would look totally different. They were happy to go ahead with my quote and we booked in a suitable time to carry out the work.

Cleaning and renovation of a Riven Green Slate Tiled Kitchen Floor

Were happy to take on work of any shape and size and as jobs go this was one of the smaller floors I’ve been asked to work on.

Work began with the application of a coarse 200-grit diamond pad fitted to a weighted rotary floor buffer. The pad was worked into the floor using a strong dilution of Tile Doctor Remove and Go for extra cleaning power and lubrication. The scrubbing action releases a lot of dirt and old sealers etc from the Slate turning the solution black. This was then rinsed off with water and the soil extracted with a wet vacuum.

Old floors like this one don’t have a damp proof membrane installed under the stone and so it’s quite common to see moisture from underneath the floor rising through the stone and depositing minerals including salts on the surface as the moisture evaporates. This problem is commonly known as effloresce and to counter it I like to neutralise the alkaline salts by giving the floor an acid rinse. This involves further cleaning the stone using a dilution of Tile Doctor Grout Clean Up which is scrubbed into the stone and then rinsed off with water and extracted afterwards. Not only does this dissolve any salts is also neutralises the use of alkaline cleaners and etches the stone slightly so you get a better bond with the sealer.

Once the floor cleaning part of the renovation plan was complete attention turned to knocking out the old failing cement that was used to grout the Slate slabs. With the rubble cleared away the stone was repointed using a modern breathable and flexible product that will cope with any moisture rising through the floor. Once dry the floor was then cleaned again removing all the soil with a wet vacuum and left to dry overnight.

Sealing a Riven Slate Tiled Kitchen Floor

Calling back the next day one thin coat of Tile Doctor X-Tra Seal was applied which added a bit of lustre and this will add strong protection to the stone. X-Tra seal is a premium product, but it was the perfect product for this stone and situation as its formulated using an oil-based resin that will bring out the colour of the green slate; it’s also fully breathable and waterproof so it’s a great sealer for use in high traffic internal or external areas.

Riven Green Slate During Sealing in Leyland

Again, it’s not a cheap sealer but for old rough stone floors in an old house without a damp proof membrane it ticks all the right boxes. Once done the floor was complete and it looked so much cleaner and healthier.

Riven Green Slate After Sealing in Leyland

As usual I discussed after care with my client and recommend they use Tile Doctor pH Neutral Cleaner which is a lot milder than the bleach based cleaners you often find on supermarket shelves. These stronger products can damage the seal (not the stone) and within weeks or months of using that type of cleaner the sealer will be compromised. It’s the sealer that stops dirt from becoming ingrained into the pores of the stone so it makes sense to use a cleaning product that will maximise its life.

Renovation of a Black Slate Kitchen Floor in Lancaster

1 Comment / Lancaster Tile Cleaning, Slate Tile Cleaning, Work History / Russell Taylor

The photographs below are of a dull and dirty Black Slate floor that I was recently asked to renovate at a property in the City of Lancaster which is a few miles south of our base in Carnforth.

Black Slate Floor Before Renovation Lancaster

Slate isn’t very porous which is why you often find it being used as roofing; however, this means any sealer applied is primarily active on the surface where it is more prone to wear from foot traffic. Regular cleaning with a pH neutral tile cleaner combined with topping up the sealer every 12 to 18 months will make the sealer last a lot longer. This rarely happens though and once a sealer has been worn off dirt will begin to penetrate the stone making it difficult to clean and dull.

In this case my client explained that the sealer had been applied by the tiler a few years ago and that they had been using washing up liquid to clean the floor. pH levels for washing up liquids vary but the most popular product has a pH level of 9 which is far too acidic for use on a sealed tile and slowly stripped the sealer away. I discussed with the client the process for renovating the slate floor, agreed a price for the work and arranged to come back a few weeks later.

Cleaning a Black Slate Floor Tiled Kitchen Floor

To renovate the floor, I first attached a coarse 200-grit Diamond pad to a buffing machine and ran it over the floor using water as a lubricant. This removed what was left of the old sealer deep cleaned the stone. The Grout was then scrubbed with Tile Doctor Pro-Clean and the floor was then rinsed with water and the soil extracted with a wet vacuum.

The floor was then inspected, and stubborn areas were spot treated with a little Tile Doctor Remove and Go which was sprayed on and left to soak in for ten minutes before being scrubbed in and rinsed off.

We finished the clean with a 400-Grit diamond padf followed by an Acid Wash with Grout Clean-Up, this left the Slate with a slightly acidic pH which helps bond the new sealer and counters the alkaline pH of the floor following the use of alkaline cleaning products.

Before we sealed the whole floor, we always do some damp testing to make sure it is dry before sealing. This was an old floor with no damp proof membrane underneath so it needed to be very dry before we could apply the sealer.

Black Slate Floor Moisture Testing Before Sealing Lancaster

The client wanted a very high gloss finish, so we applied four coats of Tile Doctor High Shine sealer which is an acrylic sealer ideal for achieving this affect. If the floor wasn’t fully dry, we would have left it another day or two, but we find you can often speed up the drying process with the use of a dehumidifier and some air blowers.

The client was very happy with the transformation in the Black Slate floor, they had looked dull and drab for quite a while and it was refreshing to see them look like new again. They also felt more confident that now they understood what had caused the problem and would be better able to maintain the floor going forward.

Bolivian Black Slate Floor Before After Renovation Blackpool

Renovating a Bolivian Black Slate floor in Blackpool

1 Comment / Blackpool Tile Cleaning, Grout Cleaning, Slate Tile Cleaning, Work History / Russell Taylor

This kitchen floor in Blackpool was laid 20 years prior and comprised of Bolivian Black Slate inlaid with White Ceramic Tozzettos. The slate was now looking dull and unloved and the owner now wanted the floor deep cleaning and resealing to restore its appearance.

We visited the property in Blackpool to inspect the floor and discuss what would be needed to restore the floor. It was clear that the old seal had worn away with use which left the stone vulnerable to ingrained dirt and hard to keep clean. Additionally, there were a few broken tiles near the glazed patio doors that would need replacing but the rest of the floor was solid and just in need of some love and care.

Bolivian Black Slate with White Ceramic Tozzettos Before Cleaning Blackpool

We discussed the process which would involve tile replacement, tile and grout cleaning and then sealing. I worked out a price to complete the job which was accepted and booked in for later in the month.

Cleaning and Repairing a Bolivian Slate Kitchen Floor

We cleaned the tiles with a strong dilution of Tile Doctor Remove and Go which was sprayed onto the floor and left to soak in for ten minutes before being scrubbed in. To scrub the floor, I used a rotary buffing machine fitted with a with a black scrubbing pad and approximately 15kg of additional weight to give the pad more bite. This removed what was left of the original matt sealer which was still evident in the less used parts of the floor. This process released the ingrained dirt from the stone into the cleaning solution which was then rinsed off the floor and extracted with a wet vacuum.

The grout was then deep cleaned with Tile Doctor Pro-Clean which was scrubbed in with a narrow brush and finished with a wire brush on some of the more stained grout lines. After this the wet vacuum was used again machine to extract the loose dirt and sediment and the floor rinsed down with water a few times to restore the pH balance in the floor. With the cleaning finished the floor now needed to dry off so it would be ready for sealing the next day.

Next step was to turn my attention to the cracked tiles near the patio door. I suspect the patio doors were not an original feature and there had been some settlement over the years in the underlying cement. The cracked tiles were removed, and old adhesive and grout scraped out. Fortunately, the customer still had some spares, so these were laid in place with rapid setting adhesive and then grouted in.

Sealing a Bolivian Tiled Kitchen Floor

On the 2nd day we applied a tester of 2 coats of Tile Doctor Seal and Go in a corner area as the customer wasn’t sure if she should stick with a matt colour enhanced finish or satin. The customer liked the satin finish, so we applied four further coats of the Tile Doctor Seal and Go throughout. Each coat is left to dry before applying the next so this process can take some time.

The floor looked fabulous when finished in fact the customer said it almost looked like new, which wasn’t bad for a floor that was 20 years old!

Bolivian Black Slate with White Ceramic Tozzettos After Cleaning Blackpool

As usual before leaving we discussed aftercare which for the regular cleaning of the Slate I recommend Tile Doctor Neutral Cleaner. Neutral Cleaner as its name suggest is pH neutral so it won’t damage the sealer which can be a problem for cleaning products you find in supermarkets which are basically too strong. You really do need to check the label when choosing a cleaning product for a natural stone or sealed floor as many products are made from a derivative of a bleach which will erode the sealer prematurely with regular use.

Renovating Dull Semi Riven Black Slate Flooring in Bentham

1 Comment / Bentham Tile Cleaning, Slate Tile Cleaning, Work History / Russell Taylor

This is a Semi Riven Black Slate floor which had been installed throughout much of the downstairs floor at a property in Bentham which is right on the Eastern edge of Lancashire. The Black slate and Grout had seen some wear and was now more Grey than black and having recently installed a new Kitchen the owner wanted the floor to look its best.

Rough stone can be especially hard to maintain if the wrong sealer has been applied. With rough or textured stone, it’s always best to use an Acrylic Sealer (aka ” Topical sealer”) where possible. Unlike a Matt finish impregnating sealer a Topical Sealer is designed to sit on the surface of the Stone preventing dirt from getting caught in the nooks and crevices making it much easier to clean.

Rough Black Slate Floor Before Cleaning Bentham

After surveying the floor, I recommend burnishing the stone with a coarse pad to deep clean the stone and remove any remaining sealer, then seal with Tile Doctor Seal and Go which is a Topical sealer which we find always has provides good results on this type of floors. Happy with the price and keen to get the floor renovated we were given the go ahead and scheduled a date to return to do the work.

Deep Cleaning a Semi Riven Black Slate floor in Bentham

The last thing we want to do is cause any damage to their beautiful new wooden kitchen. So before starting the cleaning process I applied clear silicone to the base of the new Kitchen units, this prevents water from the cleaning process seeping into the woodwork through capillary action.

Rough Black Slate Floor Applying Silicone Bentham

To get the tiles clean we burnished the stone floor with a coarse 200-grit Diamond pad fitted to a buffing machine running at slow speed and using water for lubrication. This gives a really deep clean and was followed up with the application of a black scrubbing pad to remove any excess resin released from the Slate which is quite common with Black stones due to the oil content. Once the Slate was clean, we turned our attention to the grout which was scrubbed with Tile Doctor Pro-clean. The floor was then rinsed with water and the soil extracted with a wet vacuum, once done the floor was left dry out.

Whilst at the property we managed to resolve a problem with a poorly laid slate tile in the hallway which the customer had often tripped over, so much so they had covered it with a rug, which was fine, but you couldn’t see the Slate. Rather than lift and relay the tile I managed to cut back the surface of the stone with a hand held flex machine using several different diamond grits. You can see from the pictures how this looks before, during and after the seal. A further advantage of treating the stone in this way is that the slate takes on a more polished finish as the rough texture is cut back. The results speak for themselves and the customer certainly won’t be tripping over the tile from now. With no further need for the rug they can get the full benefit of the slate floor.

The floor was left to dry off overnight and we returned the following day to apply a sealer first checking the floor was dry using a moisture meter. All was well, so we started to apply the first of several coats of Tile Doctor Seal and Go. It was a large area across multiple rooms, so it took some time before the job was complete.

The sealer added a lovely subtle sheen to the floor and restored the black colour in the Slate, the grout was also much cleaner and floor look transformed from the grey dull appearance we first experienced. As usual before leaving we talked about aftercare, using warm water (not hot or cold) with a mop and bucket and half a cap of Tile Doctor concentrated Neutral Tile Cleaner. Using the correct cleaning product will ensure they get maximum life out of the sealer.

Dull Riven Black Slate Floor Transfored in High Bentham

1 Comment / Bentham Tile Cleaning, Slate Tile Cleaning, Work History / Russell Taylor

We were asked to come and advise a customer regarding their stone floor which the customer was struggling to keep clean. The property was in High Bentham which lies on the River Wenning, just West of the Yorkshire Dales National Park.

Slate Floor Before Cleaning High Bentham

We often get customers who give up looking after their tiles after a while as some stone like this Black Riven Slate need quite a bit of upkeep to keep them looking good and a standard mop and bucket at times isn’t enough to keep them looking pristine. In this case the sealant had worn away in the high traffic areas and the floor had a slightly rough texture to the surface which meant it was holding onto dirt making it difficult to keep clean. We proposed the floor should be cleaned and resealed, discussed the cost and agreed a time for the work to be carried out.

Cleaning a Black Riven Slate Tiled Floor

To get the tiles clean we burnished the stone floor with a coarse 200-Grit Diamond pad fitted to a weighted buffing machine using water for lubrication. The floor was then rinsed and then the process repeated using a series of different graded pads, namely the 400 and 800 grit burnishing pads which further cleaned and resurface the appearance of the stone.

The grout was cleaned using Tile Doctor Pro-Clean which was scrubbed into the grout lines by hand; Pro-Clean is a heavy-duty cleaner which gets to the really stubborn stains and it did a great job at getting the grout looking like it should. The cleaning process was then finished off by rinsing the floor with water and extracted the slurry with a wet vacuum. The floor was inspected and retreated to the same process where more work was required. We usually find leaving Pro-Clean on a stain for longer and assisting with a bit of steam helps to lift the dirt out of the pores of the stone.

Once cleaned thoroughly we rinsed the floor again and then extracted as much moisture from the floor as possible with a wet vacuum before leaving it to dry off fully overnight.

Sealing a Riven Black Slate Tiled Floor

We called back the following day to apply a sealer first checking the floor was dry using a moisture meter. All was well, so we started to apply the first of two coats of Tile Doctor Colour Grow, a third coat was attempted but the slate would not accept any more sealer, and this was removed with a cloth. It is important to know if you have reached FCS (Full Cure Sealability) if not then the pores of the tiles will still be open to accepting dirt and the job won’t last long. Over a very short period of time the tiles will diminish in stature and finish.

The sealer really restored the black colour to the Slate and transformed the look of the floor. As always, we left the customer a free bottle of Tile Doctor Neutral Cleaner, using the correct cleaning product in future will ensure they get maximum life out of the sealer.

The floor looked lovely when finished and the customer was very happy with the overall result.

Copper Slate Tiled Floor Before and After Cleaning and Sealing Heysham

Rough Copper Slate Tiled Floor Renovated in Heysham

1 Comment / Grout Cleaning, Heysham Tile Cleaning, Slate Tile Cleaning, Work History / Russell Taylor

This customer in the coastal village of Heysham had recently had these beautiful Copper Slate Tiles laid by a builder who had been working on the house. As part of the work he also sealed them with a solvent aerosol sealer. Floor tiles experience a lot of wear from foot traffic and as a result the sealer only lasted about two weeks before it had worn off and dirt had started to penetrate the pores of the stone. The photos below were taken two months after they were sealed.

Aerosol sealers are only good for wall Tiles where they experience minimum contact, we usually only recommend their use for shower cubicle or wet rooms and they need constant topping up every 6 months or so. In our experience floor surfaces receive a lot of abrasion from the traffic of shoes and so on which will diminish an aerosol applied sealer very quickly.

Cleaning Rough Copper Slate Tiles

It makes sense to clean tiled floors before applying a sealer otherwise you simply trap the dirt under the seal which will reduce its appearance. So before re-sealing the floor with something more effective it was treated to an abrasive clean using a 200-grit diamond encrusted floor burnishing pad fitted to a weighted buffer machine. The pad was run over the whole floor using water to lubricate and with the machine running at slow speed to reduce splashing.

Next step was to clean the recessed grout which pads can struggle to reach, this was done by applying a dilution of Tile Doctor Pro-Clean along the grout lines and then scrubbing it in with a stiff grout brush by hand. Once done the residue from the tile and grout cleaning was rinsed off the floor with water and then extracted with a wet vacuum.

Sealing Rough Copper Slate Tiles

The floor was left to dry off completely overnight and I returned the next day to re-seal, this time with a more suitable product. My sealer of choice for Slate is Tile Doctor Seal and Go which will not only protect the stone from dirt and staining but also adds a very pleasing sheen finish. The new sealer really brought out the black and copper colours in the stone and now looks amazing.

For long-term care I always recommend customers avoid the use of steam cleaners and acidic or strong alkaline cleaning products which can prematurely reduce the life of the sealer resulting in dirt becoming trapped in the pores of the stone again. Naturally Tile Doctor have designed a product for this which is called Tile Doctor Neutral Tile Cleaner, supplied in concentrated form when diluted with water it becomes pH neutral and safe to use on sealed surfaces. I always leave my customers with a complimentary bottle after cleaning their floor, so they are reminded what to use.

Semi Riven Slate floor Before and After Cleaning Hornby

Brazilian Grey/Green Semi-Riven Slate Floor Hornby Kitchen

1 Comment / Lancaster Tile Cleaning, Slate Tile Cleaning, Work History / Russell Taylor

Rough Slate is notorious for homeowners to maintain as dirt can quickly become trapped in the rough surfaces. The example on this page is that of Brazilian Semi Riven Slate installed in the Kitchen of a house in the village of Hornby, which while naturally cleft from the rock loses none of its texture and style and yet has a much smother appearance than the typical rough Slates from China. Less processing means it’s not quite completely smooth but it is a lot less expensive to buy than say a honed or polished Slate which is more difficult to maintain due to various polishing techniques required to keep up the appearance. Brazilian Slate is in fact one of my favourite slates to clean and also one of the most rewarding of Slates to seal as the sealer really does bring out the colour and character of the stone.

Sealers provide a protective barrier on natural stone floors and without it dirt can penetrate into the pores of the stone making it more and more difficult to clean effectively. Unfortunately on this floor the new homeowners were unaware on what sort of Stone it was and had no idea how to look after it which resulted in the sealer wearing down prematurely and the floor becoming dull and un-inviting.

Semi-Riven Slate floor Before Cleaning Hornby

Cleaning Black Semi-Riven Brazilian Slate Tiles

To restore the appearance of the Slate floor we started by taping up the edges of the new kitchen units to protect the wood from splashing. This was followed with an application of a strong dilution of Tile Doctor Pro-clean worked in with a black buffing pad fitted to a buffing machine running at slow speed (working at a slower speed results in less splashing). The pads can struggle to reach the edges and corners so these were cleaned by hand.

Once we had finished on the main floor area we then concentrated on the grout using a steam cleaner and more Pro-clean scrubbed in with a narrow stiff brush.

Last step of the cleaning was to rinse the floor with water to remove any trace of cleaning products from the Slate and then dried off the floor the best we could with our high wattage wet vacuum machine and left the floor to dry off naturally over night.

Sealing Black Semi-Riven Brazilian Slate Tiles

The next day we returned to seal the floor checking first that the floor had completely dried. The customer had requested a matt finish however we have worked on Brazilian Slate many times before and we knew how good they can look with this Satin finish sealer. Naturally its the customers decision so we offered to do a test piece and let them decide if they didn’t like it we would strip off the test piece and apply a Matt finish sealer like Tile Doctor Colour Grow instead.

The floor was dry so a couple of coats of Tile Doctor Seal and Go were applied to one Tile so that they could appreciate how it would look. Luckily the customer agreed with us and so we set about sealing the whole floor with Seal and Go.

To speed up the drying process Air Blowers were installed as we worked and it wasn’t long before the sealer was dry and the customers were able to walk on the floor and inspect every area before we left. I’m please to report that they were over the moon with the floor and my recommendation of sealer.

To maintain the slate tiles going forward we always give our customers a free bottle of Tile Doctor pH neutral tile cleaner, which is a little incentive for them to provide some feedback via our website.

Fantastic Black Brazilian Slate Tiles Rejuvenated in Thornton-Cleveleys

1 Comment / Slate Tile Cleaning, Thornton-Cleveleys Tile Cleaning, Work History / Russell Taylor

Tenuous link I know but I worked on this semi riven Black Brazilian Slate Tiles in the kitchen and dining room of a house in the seaside town of Thornton-Cleveleys around the time of the Rio Olympics. I love working on Slate as although it’s appearance can degrade without proper maintenance due to a build-up of dirt I knew they would look fantastic by the time I had finished.

Brazilian Black Slate Before Cleaning Thornton Cleveleys

The tile itself had lost its rich black colour and the grout lines had become stained, leaving the floor as a whole looking very unattractive. Out of interest honed Slate has a smooth, refined texture whereas the riven Slate has a rougher, more natural texture, and this can make it more difficult to keep clean. Needless to say, the customer was keen to have the tiles restored to looking their best.

Cleaning Black Semi-Riven Brazilian Slate Tiles

To restore the appearance of the Slate, I cleaned the floor and removed what remained of the old sealer off using Tile Doctor Remove and Go. This was scrubbed into the floor using a scrubbing pad fitted to a rotary machine. The floor was then rinsed with water, and the process repeated where necessary to tackle particularly stubborn areas of dirt.

As mentioned previously, the grout lines were in a particularly bad state, and would need special cleaning attention. I cleaned carefully with a strong 5-to-1 dilution of Tile Doctor Pro Clean with water, which is our high alkaline cleaner. The cleaning solution was scrubbed I’m using a stiff handheld grout brush, with the grout lines looking immediately cleaner. When I was satisfied that the grout lines had been restored to the best possible condition, I gave the floor a thorough rinse using the wet pickup function of a wet wax machine to get the floor as dry as possible and then left the whole floor to dry off overnight.

Sealing Black Semi-Riven Brazilian Slate Tiles

Upon my return to the property I ran some quick damp tests to check that the floor was completely dry. This is important as any excess moisture would have prevented me from sealing the tiles, since it can cloud the sealer and damage it performance.

Previously I discussed sealer options with the customer and they stated that they would prefer a Satin finish, so I applied a sealer called Tile Doctor Seal and Go, our topical sealer which will both protect the Slate from dirt and stains, and also gave it the desired finish. As you can see from the below photographs, the rich, dark shades in the Slate were really enhanced.

The customer was very pleased with the finished result, but was also concerned about keeping the Slate clean in the long-term. For regular cleaning I advised the customer to use a pH neutral cleaner for aftercare called Tile Doctor Neutral Cleaner. As a pH neutral cleaner, it will not erode the sealer compared to acidic cleaners you so often find in supermarkets.

Cleaning Rough Black Slate at an Enterprise Centre in Millom

1 Comment / Slate Tile Cleaning, Ulverston Tile Cleaning, Work History / Russell Taylor

These photographs are taken at an Enterprise Centre in Millom where local business are encouraged to network and they also offer various training courses, all of which results in a large amount of people coming and going across the 120m2 of rough black Slate which covers the communal areas. Interestingly enough this is not the first time we have cleaned and sealed this floor with the last visit being five years ago. Five years of wear and tear had taken its toll on the tiles though and the black Slate was looking tired but not horrendous given its location so I think it’s fair to say the sealer had performed well over the Intermitting period.

Cleaning Rough Black Slate

As I mentioned before the area in total was about 120m2 which is a large area so we operated in sections working around the public and ensuring the correct signage was displayed were relevant.

To clean the Slate tile and grout and remove the remaining sealer the floor a good deep clean using a dilution of Tile Doctor Remove and Go leaving it to soak in for fifteen minutes before working it in with a black scrubbing pad fitted to a rotary buffing machine. This process was followed by rinsing and cleaning with fresh water, stubborn areas were retreated and the water was removed using a wet vacuum to the get the floor as dry as possible.

Sealing Rough Black Slate

Once the section of floor was clean we left it to dry and moved onto cleaning the next section coming back later to seal it which we did with two coats of Tile Doctor Colour Grow which is an impregnating sealer that occupies the pores preventing contaminates from becoming ingrained. Colour Grow is also a colour enhancing sealer that brings out the deep colour in the slate.

The customer knew about using the right cleaning solution for regular cleaning however as it had been five years since our last visit we thought it best to remind them and recommend the use of Tile Doctor Neutral Cleaner which will not reduce the life of the sealer like an acidic cleaning product would.

Black Slate with White Marble Inserts Southport After Cleaning

Cleaning Black Slate with White Marble Inserts in Southport

1 Comment / Leyland Tile Cleaning, Slate Tile Cleaning, Work History / Russell Taylor

An unusual but attractive combination of semi riven black Slate with white Marble inserts had been installed in the hallway of this residence in the town of Southport. This floor had not been cleaned properly in some time, in fact the local Tile Shop had given the customer the incorrect tile cleaning product for the job which had slowly stripped the sealer off the tile leading to dirt becoming ingrained into the tile and making it difficult to clean which resulted in the deteriorated condition you see on the picture below:

Cleaning Black Slate and Marble Inserts

The remedy was to give the floor a good deep clean and then reseal so I got to work and applied a medium dilution of Tile Doctor Pro-Clean onto the floor leaving it to soak in for fifteen minutes before working it in with a black scrubbing pad fitted to a rotary buffing machine. This process soon had the dirt running out of the floor and the soiled solution was removed using a wet vacuum. The process was repeated for stubborn area and this time the grout was scrubbed by hand using a stiff brush and more Pro-Clean. Pro-Clean is a multi-purpose alkaline based cleaning product that’s safe to use on Tile, Stone and Grout and given there was hardly any sealer left it wasn’t necessary to use a stronger dilution.

Once I was happy with the floor it was washed down with more water to remove any trace of cleaning products and then the water removed using the wet vacuum and then left to dry overnight.

Sealing Black Slate and Marble Inserts

We have a number of sealing products suitable for Slate and Marble each one with a different effect but given then floor was predominately slate I decided opt for four coats of Tile Doctor Seal and Go which provides stain protection and leaves a nice low sheen finish.

Before leaving I let them know about Tile Doctor Neutral Clean which is a cleaning product that has a near neutral PH and is specially designed for cleaning sealed floors.

Silver Pearl Milled Slate Lancaster After Cleaing and ReSealing

Cleaning and Milling Silver Pearl Pearlescent Slate floor in Lancaster

1 Comment / Lancaster Tile Cleaning, Slate Tile Cleaning, Work History / Russell Taylor

Previously I had solved a lippage problem on this customers Limestone kitchen floor where the tiler had laid the tiles unevenly and they had asked me to remove and level the edges which we can do with diamond encrusted burnishing pads. I sorted that out and they asked me back to look at their Conservatory floor as well which was a Silver Black Pearlescent Slate, again laid with lippage but the slate had also been oiled prior to sealing causing it to loose all its Silver colouring making it look black all over. It was at this point the customer shared the whole story of how the floor had been laid when she had been away on her holidays and had trusted the Tiler to do a good job; unfortunately he hadn’t and was unable to correct the problem. The floor was left in a sad and sorry state for a number of years and the owner unhappy with the floor had to cover most of the floor in rugs so she wouldn’t trip on the lippage. It probably would have stayed that way until one day they noticed my Tile Doctor Van in a Lancaster car park where they stopped me so to get my business card.

So a few days later I called round to assess the problem and came up with a solution; I offered to Mill the whole floor with Diamond segments using burnishing pads and just to prove my faith in this system to help solve her floor issues, I moved the settee away and proceeded to Mill a small section, after rinsing with water and Vaxing the waste up, the customer was delighted with the results, not only had the rough lippage disappeared but she could see the Silver Pearlescent colour shine through the Black Slate, which is exactly why she bought the Tiles. We think the Tiler oiled the floor to darken it so you couldn’t see what a bad job he had done on laying the tiles, unfortunately this didn’t stop people tripping over them.

The great thing about milling a stone tile is it actually improves the look not diminish it, unlike wood the more it’s worked at the better it will look. I spent an extra day on this floor to get it right for the customer and the results were very satisfying for us both especially after I had put down several coats of Tile Doctor Seal and Go on The Slate to lift the colours in the stone and also add a sheen to the tiles as well.

Silver-Pearl-Milled-Slate-Lancaster-After-Cleaing-and-ReSealing.jpg

I always mention to my customers the importance of using a nuetral cleaner like PH Neutral cleaning product for aftercare cleaning and not to use a bleach based cleaning product like flash, Domestos etc, or even Washing up Liquid which is slightly Acidic; all these will damage a stone sealer given time and diminish it’s protective qualities.

Black Honed Slate Tiled Floor in Ambleside Pub Toilet

Slate Tile Cleaning, Work History / Russell Taylor

I guess it was inevitable that I would be asked to clean the floor in a public toilet at some point; fortunately for me this one in a pub in Ambleside Cumbria was in a reasonably pleasant condition. The floor was Black Honed Slate Tiles but the sealer had been badly etched by Uric Acid (aka urine) around the cubicles, and a bad smell was building up from the reaction with various sealers and coatings that had been applied previously which were unsuitable for a stone floor. Ambleside of course is in the centre of the English Lake District which is famous for its walking and so naturally these floors tend to get a lot of muddy boots trampling over them from the thousands of tourists that visit this area every year.

Cleaning the Black Honed Slate Tiles

I manage to strip the products from the floor using Tile Doctor Remove and Go combined 50/50 with Nano-Tech Ultra-Clean followed by the use of a Steam Cleaner which neutralised the remaining odours as well as helping to remove any remaining cleaning products. Finally the floor was rinsed with water all of which was removed using a wet Vaccum and then left to dry before sealing.

Sealing Black Honed Slate Tiles

We have a number of sealing products for Slate tiles, each one providing a different effect; in this case we opted for two coats of Tile Doctor Colour Grow which enhances the colours in the natural stone and provides stain protection combined with a nice matt finish, which was very practical for this situation. However the customer wanted a higher sheen effect so we added two coats of Tile Doctor Seal and Go to the surface as well. It isn’t always possible to do this with sealers as their can be compatibility issues.

Before leaving I left the customer with a bottle of Tile Doctor Neutral Cleaner which is an PH neutral product specially designed for cleaning sealed stone floors.

Painted Slate Floor Restored

Grout Cleaning, Slate Tile Cleaning, Work History / Russell Taylor

Recently restored a Slate floor in a kitchen which was covered in paint, grout haze and cement. The answer was to mill the slate which got rid of the paint and the roughness of the slate and 90%of the Grout haze.

Painted Slate Floor before Restoration by Tile Doctor Lancashire

We used Tile Doctor Grout Clean-Up to remove the remaining grout haze, rinsed the tiles down with water and then left them to dry overnight. Once dry (the next day) we applied 5 coats of Tile Doctor seal and Go, which gave them a sheen and lifted the deep colour in the Slate, which had not been diversely afftected by the use of the Milling pads but instead help to lift the colour out of the Slate instead, this system works equally well with Sandstone.
