These Indian Fossil Sandstone tiles (sometimes known as ‘Yorkstone’ tiles) at a property in the small town of Swanland near Hull were, on initial inspection, in great condition, with no cracks or damaged tiles. However, thanks to a lack of sealer, the tiles had become ingrained with dirt, resulting in a heavy soil buildup that dulled the appearance of the stone. Also noticeable were some unsightly cement splashes around the grout lines.
Cleaning an Indian Fossil Sandstone Floor
I started the job by tackling the cement splashes around the grout lines. In this case I opted to carefully break them down manually using a good old fashioned hammer and chisel, whereas when it comes to stubborn adhesive and paint stains I would recommend a specialised cleaner such as Tile Doctor Remove & Go.
The first step of cleaning the main area of Sandstone tiles was to mix a solution of one part Tile Doctor Pro Clean to four parts water, before applying it to the stone and scrubbing it in with a black pad fitted to a rotary machine. This helped to break down the heavy soil build up, and is an effective method for doing so on most types of natural stone floor.
Sealing an Indian Fossil Sandstone Floor
After completing the clean, I left the property to allow the floor to dry overnight. Upon my return the next day, I checked for excess moisture and, once satisfied the floor was dry, I proceeded to seal the floor with four coats of Tile Doctor Seal & Go. Checking for excess moisture prior to sealing is essential as it can cloud the sealer and damage its performance.
Seal & Go is a water-based topical sealer designed to build up stain resistant
protection on the surface of the floor and to allow moisture vapour transmission. It
is typically used to seal internal, unsealed porous surfaces, including Sandstone,
Quarry and Victorian tiled floors and being water based you don’t get a smell as it dries.
