Although we do get a lot of residential work we also cover commercial properties such as this local bowling complex in Slough where complaints of a bad odour in the male toilets had been received. The owner of the bowling complex realised the problem was coming from the slate tiled floor and decided to call in their local Tile Doctor to identify and eliminate the odour.
Cleaning Slate Tiles
Our first action was to use Tile Doctor Remove & Go, a tile and stone friendly stripper, which we applied liberally to the toilet floor. This particular solution is highly effective at removing protective sealers, whilst also drawing out ingrained stains and removing any heavy grease build-up. The solution was allowed to sit for a short period of about ten minutes. It is important not to leave the product to dwell on the surface for too long in case it dries completely. Next, we added a small amount of water to the Remove & Go, before employing a heavy weighted rotary with a nylon brush to carefully scrub the slate and grout lines.
Sealing a Slate Floor
As the bowling complex experiences high volumes of customers on a daily basis, it was essential to use a sealer which would provide the floor with durable protection. We advised our client that an impregnating sealer rather than a topical sealer would be the most suitable for use in this type of environment and recommended a combination of Tile Doctor Stone Oil and Ultra-Seal (suitable for use on all natural stone, including slate) be used instead.
Impregnation sealers, such as Ultra-Seal and Colour Grow, are absorbed by the pores in the stone, offering both stain and soil resistance, and providing protection from within. In addition, they are usually solvent-based, and provide durable protection even in areas which experience high traffic. By comparison, topical sealers will essentially build up layers on top of the stone in order to offer protection. The downside to using this is that, in high traffic areas, the sealer can be effectively ‘kicked’ or walked off the surface of the stone.
You’ll notice in some of the photos that the grout appears to be a different colour after cleaning. That’s because the grout had been repaired by the bowling complex prior to our work on the floor. This mistake has been realised, however, as they have matched the grout in with the dirty discolouration, rather than the clean so addressing this issue will be another job on their list!
Overall, our client was left with a cleaner and more durable slate floor.
