Sandstone is a particularly popular choice for kitchen and hallway floors amongst home owners in the UK. It not only possesses beautiful natural shades and features, but it is also typically hard wearing, making it an ideal stone for tiled flooring in high traffic areas of a house and can often be found laid as large riven flagstones in pubs and other commercial premises.
Naturally, just like any other type of tiled floor, Sandstone needs to be maintained using appropriate products and methods. A lack of adequate surface sealer in particular leaves Sandstone susceptible to ingrained dirt, and can leave distinct, unsightly patches such as those in the photograph below.
In this instance, I visited a client in the old Essex town of Thaxted, who believed that her four square meter Sandstone tiled floor might be suffering from damp issues after lifting up the mats covering the area.
However, when I arrived at the property and ran damp tests, I found the issue to be superficial. The Sandstone floor however did require attention in the form of a deep clean and a fresh seal to tackle the white patches and prevent further discolouration.
Cleaning a Sandstone tiled floor
To begin the cleaning process I spread Tile Doctor Remove & Go evenly across the floor. It was left to dwell for approximately 15 minutes, during which time it worked to break down the old sealer remaining on the tiles. I then agitated the area twice over with both a black scrubbing pad fitted to a rotation machine lift away any dirt.
The resultant slurry was removed using a wet vacuum and the floor was then rinsed with water and then mixed a strong solution of one part Tile Doctor Pro Clean to three parts water which was used to give the floor a final clean and scrub the grout clean before using the wet vacuum again and giving the floor a final rinse with water.
Sealing a Sandstone tiled floor
After completing the cleaning process I left the floor to dry over the weekend. Upon my return to the house I proceeded to seal the tiles with three coats of Tile Doctor Colour Grow which is an impregnating sealer that soaks into the pores of the stone and provide durable surface protection going forward. Colour Grow is also specially designed to let the floor breathe and enhance the natural colours in the stone and, in this case, really helped to intensify the natural sand-coloured shades in the tiles.
The difference made to these Sandstone tiles was really noticeable, with the white patches completely removed and the surface more generally back to looking like new, needless to say, my client was very happy with the results.
