I carried out a cleaning sample using Tile Doctor HBU Remover, which is a strong cleaning solution, applied it to one tile in the utility room and the dirt was removed with exceptional results; I then dried the tile with a heat gun to show the customer the results which she was delighted with.
Sandstone Tiled Floor Cleaning
For the rest of the floor I begin by wetting the surface and carried on treating it with more HBU remover diluted 50% with Tile Doctor Pro-Clean which made it thinner and more effective for deep cleaning. Using a stiff sweeping brush with bristles about half inch long (well broken in for this type of job) I then scrubbed away at the tiles and then the grout joints using a small hand held scrubbing brush which I always find is more effective than a machine which can make a lot of mess and can be overly aggressive. I cleaned the tiles in 5m2 sections rinsing each section four times to ensure there were no trace of cleaning solutions left behind. When finished the floor was left to dry for two to four hours and I tested for moisture knowing it would be ok but always worth checking.
Sealing a Sandstone Floor Sealing
Sandstone was sealed with four coats of Tile Doctor Colour Grow. An impregnating and colour enhancing product which will protect the floor for many years to come.
I tested the floor with a water test to ensure it was fully sealed, this is a simple test whereby you check to see if drops of water applied to the surface form beads on the tile. The end result was incredible as you can see the tiles looked as good if not better than the day they were cut from the quarry, and the Colour Grow certainly enhanced the true colours in the stone.
