Sandstone Tile Cleaning

We were contacted by a new homeowner in Rawtenstall, which is in the borough of Rossendale, who having just moved in decided to contact us about her Sandstone kitchen floor. The stone floor was terribly dirty and was proving impossible to clean.

The stone was very smooth and having discussed it locally she had been told it was Kerridge Sandstone. I suspected from our conversations that it had not been sealed successfully as apparently even water from wet shoes would soak straight into the stone and cause staining.

I went over to survey the floor and discuss its renovation. Whilst there I was able to confirm the issues with the sealer and recommended deep cleaning the stone floor, stripping off what was left of the old sealer in the process and then re-sealing with something more durable.

I worked out a renovation plan and price, which was agreed, and scheduled a date for the work to start. Due to the unknown history of the floor, I expected the plan was going to require some adjustments to achieve the best result.

Stripping and Cleaning a Kerridge Sandstone Tiled Kitchen Floor

Working in sections the initial focus was to get the floor clean which started by soaking the sandstone floor in a strong solution of Tile Doctor Remove and Go. This product is a coatings remover and was left it to soak into the stone for ten minutes so it could get a head start breaking down the dirt and old sealer.

The solution was then agitated with a rotary buffer machine fitted with a coarse 200-grit diamond pad. This action released the dirt from the pores of the stone bringing it to the surface and turning the cleaning solution black. The grout was also given a scrub by hand to make sure it was as clean as possible. During the process the soiled solution was rinsed off the floor with water and then extracted with a wet vacuum as needed.

After another rinse and extraction, the floor was given and acid rinse using Tile Doctor Grout Clean-up. This further cleans the stone and neutralises the pH level of the floor after the use of Tile Doctor Remove and Go which is a strong alkaline.

After another rinse with water and extraction with the wet vacuum a 400 and then 800-grit burnishing pad was run over the floor to refine the appearance of the stone following the use of the coarser pads earlier. Only water is used during this process to help with lubrication, and this turns into a creamy liquid which is rinsed and extracted after each pad.

The floor was dried as much as possible with the wet vacuum before being left to dry off fully overnight.

Sealing a Kerridge Sandstone Tiled Kitchen

The day after the floor was tested with a damp meter to check it was dry and then sealed with Tile Doctor X-Tra Seal which is a modern oil-based product that enhances colour and adds a slight sheen appearance that really lifts the floor. This product is an impregnator that works by soaking into the sandstone occupying the pores and thereby ensuring dirt remains on the surface where it can be easily cleaned away.

Once complete the difference was extraordinary, the natural veins in the stone were now visible and the floor was completely transformed by the work, much to the pleasure of the new owner who left the following feedback:

“I have recently moved to a lovely cottage in the country, my dream, but my stone kitchen floor was not a dream when I found that it was impossible to clean with years and years of ingrained dirt. However, this is no longer the case!! My kitchen floor looks brand new and now compliments the rest of the room. I can’t recommend Kevin highly enough; he is professional and very skilled. Thank you, Kevin.”

For the aftercare cleaning of Sandstone flooring, I recommend Tile Doctor Neutral Tile Cleaner which ideal for cleaning sealed stone. It has a pH neutral formula so won’t prematurely erode the sealer like many of the stronger products you find in supermarkets.
