The owner of this Blue Lias Limestone tiled floor in the village of Silverdale was not happy with the installation which had occurred two years earlier and several attempts by the Builder/Tiler to put it right had not resolved the problem. Basically the floor was not flat and had several raised tile edges resulting in what is known in the trade as a Lippage problem. Fortunately natural stone can be ground down to remove this issue.
Milling and Polishing Limestone Tiles
To level a stone surface such as Limestone you need to use a special grinding disc formed of diamond segments that is attached to a heavy rotary machine and run over the tiles until the desired effect is achieved, in our case up to 4mm of Limestone had to be removed in some areas to ensure the tiles were flat. Once this was done the floor was rinsed down to remove the slurry that was generated from the milling process and also scrubbed clean with a dilution of Tile Doctor Pro-Clean with particular attention paid to the grout lines.
Once the surface was level the next step is to burnish the Limestone tiles and restore the polish which is done via the application of a different set of diamond encrusted pads
which come in a set of four. You start with a coarse stripper pad with water to strip back the surface and then move onto the finer pads to polish the floor.
Sealing Limestone Tiles
Being a natural stone the tile needs protecting from contaminates which can stain and this is especially relevant in a kitchen. So the next step was to wait for the floor to dry and then seal it using two coats of Tile Doctor Colour Grow which is an impregnating sealer that soaks into the pores of the stone. Colour grow is a great sealer to use on natural stone as not only does it offer good stain protection but it also brings out the colours in the stone.
Whilst sorting out the floor we noticed that the skirting boards and kitchen units had not been sealed to the tile with silicone to prevent water ingress that could damage the wood so to finish the job off we sealed in-between.
The customer was extremely pleased with the end results as they were considering taking it all up and starting again, and left the following feedback on the Tile Doctor website.
We’re absolutely delighted with the result. The floor, of blue limestone, was laid unevenly and unpolished. Russell and Heidi removed the lippage, polished and buffed the stone and sealed it properly, so it now looks the way it ought to have looked in the first place. It was certainly not cheap; but it was considerably cheaper than having a new floor laid – and it was done in three days without putting the kitchen completely out of action.
