This post comes from a lovely house in Ticknall, Derbyshire where the owner had installed a Welsh Slate Tiled Floor in their Kitchen ten years earlier. Welsh Slate is renowned the world over for its quality however ten years of use in a high traffic does take its toll and the customer complained that she wanted the tiles to look colourful with a matt finish but they always looked dull and dirty even after cleaning with mop.
Interested to know the history of the floor I asked when it was last sealed and apparently it had not been redone since it was installed. It was clear to me that any sealer had long since long worn off and now dirt was becoming trapped in the pores of the stone making it difficult to clean effectively.
Cleaning a Dirty Slate Tiled Floor
To get the Slate clean I applied a strong dilution of Tile Doctor Pro-Clean which as well as cleaning deep into the pores of the tile should also deal with any remaining sealer. I left it to soak into the tile for about ten minutes before working it in with a black scrubbing pad fitted to a rotary buffer machine. After this I rinsed the floor with water and extracted the now soiled cleaning solution with a wet vacuum.
At this point it became apparent there were some stubborn stains in front of the oven that needed dealing with so I scrubbed in a solution of Tile Doctor Grout Clean-Up which is an acid based product that is great for removing mineral deposits such as salts as well as grout smears. This worked well and the floor was now in ready for sealing so I gave the floor a good rinse to remove any trace of product and left it to dry.
Sealing a Slate Tiled Floor
The floor was about 7 square meters in size and being relatively modern it had a Damp Proof Membrane and Underfloor Heating installed, as a result it was fully dry within three hours and ready to take a sealer.
With the floor now dry I started applying the sealer which in this case was Tile Doctor Colour Grow. Colour Grow is an impregnating sealer that penetrates deep into the pores of the stone, thus acting as a shield against ingrained dirt whilst enhancing the natural colour of the tiles to provide an aesthetically appealing appearance. You may recall the owner had requested a matt finish so after applying a couple of coats the job was done.
With the tiles clean and now protected with the colour enhancing matt sealer I asked the customer to inspect the floor. As you can imagine she was very pleased with the result and left the following comment on the Tile Doctor feedback system.
“Mr Mall was a very efficient, hardworking and helpful worker. The end result was excellent and I am delighted with the outcome. Highly recommend…”
