This Shell Slate tiled floor was installed in the kitchen of a house in Lytchett Minster and had not been sealed after its installation over twenty years ago and had now become deeply ingrained with dirt which the owner could not remove however hard she tried.
Cleaning Shell Slate Tiles
To clean the tiles I used Tile Doctor Pro-Clean diluted one part cleaner to five parts water, the solution was applied it to the floor and then left to soak in for ten minutes before working it in with a Numatic buffing machine fitted with 17″ medium firm brush. Next the tiles were steamed using an Earlex steamer and stubborn stains cleaned by hand using sections from a cut-up black buffing pad and a Spid brass-coated wire brush where necessary. Being riven slate the floor was too uneven to successfully clean using a black buffing pad fitted to a rotary machine as the sunken parts of the tile would have been missed and so cleaning tile by tile was the only option to ensure the slate was returned to the best possible condition. A stiff brush was also run along the grout lines before thoroughly rinsing the floor to remove any trace of cleaning product.
Sealing Shell Slate Tiles
The floor was left to dry overnight and I returned the next day to seal using two coats of Tile Doctor Colour Grow sealer which is a penetrating sealer that occupies the pores in the tile preventing contaminates from lodging there and enhances the many beautiful colours of the Slate as well as leaving a subtle shine to floor.
The customer was very pleased with the result and said that she hadn’t before seen the true colour of her floor.
