Tired Black Slate Tiled floor in Sevenoaks restored
The photographs below are of a black slate tiled floor in the kitchen and utility room of a house in Knatts Valley, Sevenoaks Kent, it was laid around six years ago when the kitchen was installed. The owner was now having the whole kitchen re-decorated and was considering laying a new floor as the current slate looked so tired and was difficult to clean.
Cleaning Black Slate Tiled Floor
Normally I would use a strong solution of Tile Doctor Pro-Clean solution mixed with Tile Doctor Nanotech Ultra-Clean and a floor buffing machine, but due to the deep riven nature of the slate, the floor would have to be scrubbed manually. The floor had been sealed originally and although old and broken there was still a lot of sealer on the floor which all had to be removed. I decided to use the blanket system, which involves a mixture of Tile Doctor Remove & Go mixed with Nanotech Ultra-Clean 70:30 mix. This mixture was applied to floor, and covered in plastic to prevent the solution from drying out. This was left on the floor for two hours, and then scrubbed off, you can just use a natural bristled scrubbing brush, but I find them cumbersome with the solution, so I opt for oversized pan scrubbers, which are pliable for getting into deep riven tiles. As the solution was scrubbed it was rinsed with water and removed with a wet vacuum. When everything was removed for from the floor and vacuumed up, I rinsed the floor again with water and vacuumed up to ensure all the solution had gone, the floor was then left for 48 hours to ensure it had fully dried out.
Sealing Black Slated Tiles
The slate floor was sealed using five coats of Tile Doctor Seal & Go, which despite being a low sheen finish, it really enhanced the colour of the black slate giving it more depth. The tiled floor was ready for light foot traffic in a few hours, achieving a full cure in 24 hours. The beauty of using a topical sealer such as Seal & Go on a riven stone is that the feel of the stone is smoother and therefore easier to mop. For everyday cleaning purposes we recommend Tile Doctor Neutral Cleaner, diluted 1:30 with water.
