This client in Gerrard’s Cross wanted to be able to see the different colours and features in their Sandstone Kitchen floor and to remove the ring marks which you can see in the photograph. They had just moved into the house in and loved the Stone floor but soon realised the previous owners hadn’t taken much care of it. They tried a selection of supermarket products to clean the floor but none of them made much of difference.
I carried out a site visit and it was clear to me that what was once a light Sandstone have literally darkened with all the dirt it had absorbed. I was confident that the dark stone could be deep cleaned and lightened to give them what they wanted, and then protected with a fresh sealer to ensure it remained that way. I worked out a quotation which they agreed to, and we arranged a date for the work to start.
Deep Cleaning a Sandstone Tiled Kitchen Floor
Day one of the work started by deep cleaning the Indian Sandstone tiles and removing as much of the dirt that become stuck in the pores of the stone as possible. To do this the floor was wetted with a strong dilution of Tile Doctor Pro-Clean which is our go to tile and grout cleaning product.
After leaving it to soak in for ten minutes the solution was scrubbed int the stone and grout using a rotary floor buffer which was setup with a black scrubbing pad. This action drew the dirt and any remaining old sealer out to the surface where the soiling could be extracted with a wet vacuum.
The next step was to refinish the surface of the stone using a set of Tile Doctor’s Diamond Burnishing Pads. Starting with a 400-grit pad to remove the ring marks in the floor created from plant pots and then continuing through the different grits from 800 to 1500 grit which gave the floor a natural sheen and then a 3000-grit pad to finish. The floor is rinsed with water between pads and the slurry generated extracted with the wet vacuum as before.
The lower grit pads are applied with water to help lubricate the process however the last pad is applied almost dry with only a little water sprayed onto the floor so by the time the process in completed its well on its way to being dry.
Sealing a Sandstone Tiled Kitchen Floor
I left the floor to fully dry off overnight and came back the next day to apply the sealer. Before starting thought I gave the floor another run over with the 3,000-grit pad just to tighten the pores before sealing.
To seal two coats of Tile Doctors Ultra-Seal were applied, this is an almost invisible product recommended for use in food preparation areas that leaves the stone in a natural finish which was the effect my client had requested. They had long French patio doors leading onto the garden and wanted to allow as much light in as possible because before the floor was cleaned the room was quite dark.
After allowing the seal to soak into the Indian sandstone I gave the floor one last buff with a fresh 3000 grit pad to burnish more of a natural sheen onto the floor and to bring out the colour definition.
Once complete the floor was transformed from dark to light and looked so much cleaner. My client was very impressed by the work and surprised at how different the floor looked with the colours coming through and said she would recommend me to her friends and family in the area.
For after care I recommended the use of Tile Doctor Stone Soap which is a gentle cleaner that won’t degrade the sealer and will help keep the patina on the stone. Most supermarket tile cleaning products are simply too strong for a sealed floor so it’s always worth checking the label in detail before buying.
