This sandstone floor was installed in a house in the village of Stodday, Lancashire, the floor was looking dull and if you look closely you should be able to see surface staining, there were also a number of marks the customer was eager for us to deal with.
We cleaned the floor using Tile Doctor Pro-Clean diluted with 10 parts warm water and worked in using a Black Scrubbing pad. This action certainly gave the floor a good clean but the marks mentioned earlier were proving stubborn to shift so we tried a stronger product called Remove and Go combined 50/50 with NanoTech UltraClean which add nano sized abrasive particles. We left the resulting formula to soak into the stone for about an hour and then used a steam cleaner to penetrate deep into the pores of the stone and lift out the dirt, this did the trick and so we then removed the cleaning products with a wet vacuum and washed down the floor with clean water to neutralise the floor before sealing and left for the evening so the floor could dry overnight.
Sealing a Sandstone Tiled Floor
We came back the next day and tested the floor with a damp meter in a few different locations to make sure no dampness remained in the stone. The sandstone was dry so we proceeded to seal the floor with Tile Doctor Seal and Go which gives a nice low sheen finish, Sandstone is fairly porous so it took five coats of sealer in the end. Seal and Go is a topical sealer and really brings out the true colour of the Stone and also leaves them a lot easier to clean with a mop as it takes a lot of the rough texture out of the stone.
