The owners of this house in Southampton called us in to breathe some life back into their slate floor which had become rather dull and had lost its shine. We took a look and could see the previous sealer had been worn down and it was in need of deep clean and re-seal, sealers will wear off over time and once they are gone dirt will start to get trapped in the pores of the tile.
Cleaning the Slate Floor
To remove any remaining sealer and give the floor a deep clean we applied a strong dilution of Tile Doctor Pro-Clean. This was left to dwell on the floor for a while before using a rotary machine fitted with a black scrubbing pad to scrub the floor and get the slate floor really clean. The machine can struggle to reach the grout so it was necessary to get in with a stiff hand brush afterwards and scrub along the grout lines. Once I was satisfied with the condition of the stone floor it was given a wash down with clean water which was removed using a wet vacuum to make sure no chemical was left on the floor as this can affect the sealer later.
Sealing the Slate Floor
Sealing the Slate floor was a straight forward process once the floor was clean and free of any debris etc. The sealer chosen for this floor was Tile Doctor Seal and Go which adds a low sheen finish whilst providing stain protection. Five coats were applied using a paint pad applicator before the floor was fully sealed , the number of coats you need depend on the porosity of the stone and each floor is different and you need to let each coat dry before proceeding to the next.
