Sandstone Tile Cleaning

Here we have a heavily riven Indian Sandstone slab floor in the kitchen of a large property in Ingham on the Norfolk Broads. It was a lovely location to work being only a mile from the market town of Stalham and about 2 miles from the Norfolk coast.

The Sandstone floor was laid by the client’s late husband whose took great pride in it. Unfortunately, the riven nature of the Sandstone had trapped a lot of dirt and particularly along the sand and cement pointing. The floor had been sealed previously with a colour enhancing impregnator however it hadn’t been properly cleaned before sealing, so dirt and contaminants were trapped under the matt finish. As a result, no end of mopping could ever get the floor clean.

To rectify the problem, we recommended removing the sealer, deep cleaning the Sandstone and then re-seal. The challenge was to ensure all the old sealer was stripped away completely along with the soiling both on the surface and ingrained in the stone. I provided them with a quote for the works which they were happy to go ahead with.

Stripping and Deep Cleaning an Indian Sandstone Tiled Kitchen Floor

We returned to the property a few weeks later to start the cleaning. Working in sections this began with the application of Tile Doctor Remove & Go initially sprayed along the grout lines and left to soak in for ten minutes. The whole floor was then sprayed with more Remove and Go and the stone and pointing scrubbed with a heavy 17″ Klindex Rotary machine. The machine was fitted with an extra 10kg weight to increase traction and a 120-grit silicone carbide brush.

Once done the floor was then rinsed and the slurry was then extracted with a high powered 3-stage wet vacuum. The floor was then checked and the process repeated in a few stubborn areas.

When I was happy the floor was clean it was given an acid rinse using a dilution of Tile Doctor Grout Clean-Up which was scrubbed into the stone and rinsed off and then extracted as before. This process further cleans up the stone, removing old grout smears and also neutralised the PH level of the floor after the use of Remove and Go which is an alkaline cleaner.

The floor was then left to dry off overnight so it would be ready for sealing the next day.

Sealing an Indian Sandstone Tiled Kitchen

The sandstone floor was sealed using five coats of Tile Doctor Seal & Go applied by hand with split-filament microfibre cloths. We selected this sealer because it provides durable stain protection and results in an attractive low sheen finish. This sealer is perfect for sandstone which is very porous in its nature and did well to bring out the natural features and colours in the stone.

My client was amazed that we had managed to renovate the floor to a higher standard than it had ever been – she said her husband would have been absolutely delighted.

For aftercare I recommended the use of Tile Doctor Neutral Tile Cleaner which is a gentle yet effective cleaner that won’t impact the sealer. Strong bleach-based cleaners need to be avoided as they will strip the sealer off the stone prematurely.
