I recently paid a visit to a customer at a house in the town of Preston to restore the colour of the grout in their bathroom which due to years of using strong cleaning products had bleached the grout of any colour. The tiles themselves were not the issue they seemed fine but the grout was looking Tired; we discussed the options and decided the best course of action would be to apply a grout colourant. Two different colours were chosen, white for the shower area and Sandstone for the toilet area.
Colouring Wall Grout
Before applying the grout colourant it’s important to give the grout a deep clean using the Pre-Treater that comes with the kit; the solution is sprayed on and scrubbed in by hand before being rinsed off with water.
Once the grout had dried I started to apply the Grout colour which restores the colour and seals the grout as well, thus making it easier to clean afterwards. Grout colouring is fiddly work but you do get the gratification of an instant change. Once done I called the customer in who was delighted with the new effect as Grout colour if used correctly looks very natural and not as if someone has painted the grout making it look false.
We discussed using the correct type of cleaning product for aftercare as this seemed to be the issue to start with and I recommended Tile Doctor Aqua-Pro as this can be sprayed onto the Tiles and mopped off which is ideal where a small amount of water is required. For regular cleaning Tile Doctor Neutral cleaner was also mentioned as this is diluted into water where more cleaning is needed and mopped onto the floor area.
We received a call to visit a house in Chorley where the grout in the kitchen tiles had gone black with the build-up of dirt and the owner was having trouble cleaning it. Porcelain and Ceramic tiles are a great choice for kitchens as they are very easy to clean however what most people don’t realise is that the top layer of grout is actually porous and can becomes stained with dirt. With the agreement of the home owner I did a test clean using a strong cleaning product called Tile Doctor Remove and Go leaving it to dwell on the tile and grout before scrubbing it in by hand and then washing off the soiled solution; you can see from the photograph below that the tile and grout cleaned up nicely so I was booked to do the job the following week.
Cleaning Tile and Grout
On my return I repeated the earlier process on the whole floor cleaning the grout with Remove and Go and working it in along the grout lines with a stiff grout brush making sure to thoroughly scrub every grout joint working in small sections at a time.
Once I was happy with the grout in a section the floor would be rinsed off with clean water and a wet vacuum was used to remove the dirty water. I did this all over the floor until all the grout joints were clean retreating areas that needed extra attention.
The next step was to give the ceramic tiles a good clean by applying a strong general Tile and Grout cleaning product called Tile Doctor Pro-Clean. The solution was scrubbed onto the floor and left to dwell for ten minutes scrubbed some more and then rinsed off. The floor was then washed down with clean water three times to make sure all the cleaning products had been removed and then dried with a wet vacuum. I then left the floor to completely dry for a couple of hours and came back later to check all the grout joints were clean and followed up with a bit of detail work on corners and edges rinsing the floor again when I had finished.
I managed to complete the job in a day and with all the cleaning the tile and grout came up much lighter than before making it look like a new floor had been installed. The customer was really happy with the final result and left the following feedback on the Tile Doctor feedback system.
Heidi cleaned a very dirty tiled floor back to its original state and it now looks superb. She was extremely professional and courteous but just as important she didn’t leave a mess like a lot of tradesmen do!!! I would have no hesitation in recommending Heidi to any of my friends to carry out similar work. A job well done!!! Chris Palmer, Chorley
A customer in Leyland near Preston reported a grouting issue with their porcelain tiled kitchen floor, the tiles were fine but the grout had become discoloured and grey, they were also finding it difficult to keep clean. This is not an unusual story for Porcelain or Ceramic tiled floors which are generally very low maintenance and you find the grout needs attention before the tiles do.
Applying Grout Colourant
On arrival I set up my equipment and cleaned the floor to make sure all the grout joints were free from any dirt etc., I then did a colour test on a less obvious part of the floor with the grout colour. I wanted to make sure the colourant would take to the grout and also to make sure the customer was happy with her colour choice.
The process for grout colouring is fairly tedious but straightforward, it involves giving the bottle a good shake and applying a small amount to a toothbrush and working the grout colorant into joints using a back-and-forth motion. I find the best way to apply it is by working in small areas and adding thin even coats to limit the amount of grout colorant that gets on the tile. They were large format tiles covering 9m2 so I only needed one bottle of buff grout colourant to do the entire floor.
After the Grout Colorant dries (it takes between twenty and sixty minutes depending on how warm the house) you mist the surface with water and let stand for five minutes, excess grout colorant is then removed from the tile surface using a white nylon scrub pad.
The floor was ready for surface traffic in 2 hours but there was a white mist over the floor which you can get with porcelain tiles so I fitted a white buffing pad to my rotary floor polishing machine and buffed the floor to remove the power and water marks, once finished the floor looked like new. Before leaving I left the customer with some after care instructions and how to keep it floor looking good for the future.
Oddly Enough I had sold these Ceramic tiles to the customer in Preston when I used to work at a local Tile Shop many years prior. I had also been back to clean and seal the grout on his floor tiles originally in 2007 and then again in January 2010 when we used a Grout Colourant on them. It’s nice to get called back like this as it shows they appreciate the service you provide; for this visit the request was to freshen up the floor tiles and also the Ceramic Kitchen wall tile and Grout which had become ingrained with Grease from the cooker.
Cleaning Tile and Grout
The total area was approximately 25m2 and it took me a day and half to give the Tile and Grout a deep clean. For the most part I used Tile Doctor Pro-Clean but for the wall tiles where Grout Colourant has been applied I used Tile Doctor OxyPro which is a ready to use Tile and Grout cleaner that comes in a spray bottle, when applying any liquid to a wall its best to mix it with air in a spray bottle as this makes it lighter and helps it stick and soak into the to the tile and grout as opposed to running down it. It was noticeable that the grout colour was mainly intact and it had just needed a good clean on the whole apart from maybe near the cooker which I topped up with new Grout colour in the original shade.
Applying Grout Colourant
Once everything had been rinsed and the grout had dried I was able to apply the grout colourant using my colour applicator (toothbrush). You have to be fairly methodical doing this so it can take a while, you can remove excess colourant by spraying plain water and scrubbing with a white pad (don’t used a coloured pad as you can transfer the dye from the coloured pad to the surface).
The surface of grout is porous and as a result it can get so dirty it becomes impossible to clean it successfully, even our most powerful cleaners struggle if it gets to this stage. If you get to this point you could use the flat end of a screwdriver to scrape out the grout and re-grout the whole floor to ensure a consistent colour, naturally this is arduous work and can be time consuming however there is a second option and that is to apply a Grout Colourant instead. The grout colouring products we use not only change the colour but it also provides a protective barrier that seals the grout as well ensuring it keeps it appearance well into the future.
Preparing the Grout
Before applying a Grout Colour it’s important to ensure the grout is clean of grease and any sealer that may have been applied to the adjacent tile; Tile Doctor Pro-Clean is a strong alkaline cleaner that’s good for this purpose, for best results you should allow the cleaner to dwell for a while and then get into the grout joints by hand with a stiff brush. Last step is to rinse the floor down with clean water to remove any chemical that might upset the colourant, I recommend the use of a wet vacuum at this point to remove liquids from the floor.
Applying the Grout Colour
Once the grout has dried you can start applying the colourant which is a relatively straightforward process of squeezing the product onto a toothbrush and running it onto the grout. Don’t be tempted to use an old toothbrush for this purpose as it may contaminate the colourant leading to discolouration in the finish. The product sets in a couple of hours so I was able to do the whole floor in a day.
Here are some details of a small 4m2 Tile Cleaning and Grout Colouring job we did in a shower room in Lancaster. The tiles were recently laid and unfortunately the 5mm wide grout had discoloured because the tiler had used the same bucket to mix the adhesive with and some of the remnants from that had got into the grout mix. If the tiler had used a separate bucket this wouldn’t have happened. The tiler didn’t know what to do to rectify the problem so Tile Doctor got the call. He had done a good job on the rest of the bathroom and the customer didn’t want to upset him over it any further so she was quite happy to pay me to sort the problem out, as long as it didn’t look false.
Before Grout Colouring
First I cleaned the grout with the pre-treater spray that comes with the kit and washed off the excess with water. Although the directions recommend leaving the grout to dry for 2 hours I left it for 30 minutes followed by a blast from my heat gun to dry any dark wet spots, this speeds up the process immensely.
Applying the Grout Colouring
Next I applied the Grout Colourant, fortunately the tiles were ceramic and the excess grout colourant came off the tiles very easily where I had got some on by accident. The kit came with a special white abrasive cloth which is excellent at removing excess grout colourant from the tiles. I often find unglazed tiles or stone and even some porcelain tiles are slightly porous on the surface and if the grout colourant gets on to these tiles then it can be quite hard to get off. I find it’s always best to do a test first on a couple of rows, if you get any on the tiles, don’t leave it on for more than 10 to 15 minutes as it sets very hard. Porous stones should always be sealed beforehand as it will make them a lot easier to clean. Its worth noting that the Grout Colourant acts as a barrier and so will never need to be sealed, it’s also completely washable.
