This customer who lived in the old Sussex village of Vines Cross near Horam, had a lovely Flagstone floor installed in the Kitchen some years earlier but because they wanted a completely natural look no sealer had been applied. With no protection in place dirt had become ingrained into the pores of the stone over time making it dull and difficult to clean effectively.
Deep Cleaning a Lapicida Sandstone Floor
With no sealer evident on the stone there was no need to use a coatings remover on the tiles, so after protecting the Kitchen units and skirting board with plastic tape I started with a combination of Tile Doctor Pro-Clean tile and grout cleaner mixed with a small amount of another Tile Doctor product called NanoTech HBU. HBU stands for Heavy Build-Up and this product utilises nano-sized abrasive particles to assist in the cleaning process.
The solution was left to dwell and soak into the stone for ten minutes before being scrubbed in using a rotary buffing machine fitted with a black pad. With the cleaning solution on the floor I also took the time to run a stiff brush along the grout lines to make sure they were also scrubbed clean. After a while the cleaning solution became dirty with all the soil that was being released from the tile and was then extracted using a wet vacuum. The floor was then rinsed with water and stubborn areas re-treated using the same process until I was satisfied it was thoroughly clean.
Sealing a Flagstone Floor
I returned the next day to seal the floor first checking it for dampness using a damp meter. All was well, and the flagstones were dry, so I was able to proceed with sealing the stone.
As I mentioned earlier my client liked the natural look but having experienced the problems of maintaining an un-sealed floor had agreed for me to seal it with Tile Doctor Ultra-Seal. I applied a single base coat of Tile Doctor Ultra Seal as agreed and then recommended that we add a coat of Tile Doctor Seal and Go as well, just to brighten up the floor and add a slight sheen.
