This slate tiled floor was installed in the Kitchen of a house in the town of Bridgenorth which is in the Severn Valley Staffordshire. The owner of the house wanted to have the floor deep cleaned and re-sealed and so gave us a call.
Cleaning black slate floor tiles
We set about cleaning the kitchen floor with a mixture of Tile Doctor Pro-Clean mixed 50/50 with Tile Doctor Nano-tech Ultraclean which was worked into the pores of the slate tile using a slow speed rotary machine fitted with a Polyscrub scrubbing pad which can reach down into grouting as well as scrubbing the floor. I then used a wet vacuum to remove the resultant soiled solution before rinsing the floor down twice with cold water, this also neutralises the floor prior to sealing.
Sealing Slate floor tiles
I left the floor overnight to dry then came back next day and used a damp test meter to verify the floor was dry and ready for sealing. Once happy I proceed to apply three coats of Tile Doctor Seal & Go which as you can see from the photograph below has really brought out the natural colours in the slate. I used a water test after the third coat was dry to see if the water would form bubble on the surface thus indicating it was dry, which it did thereby indicating the floor was fully sealed.
Overall the job took two days and I’m happy report the customer was delighted with the outcome.
