On rare occasions we encounter extremely dirty tiled floors which have clearly not been cleaned for months, or even years. As you can see from the first photograph, this Slate tiled floor at a property in Gateside is an example of one of these extreme cases, being completely caked in thick layers of dirt that had amassed over a long time.
Cleaning an Extremely Dirty Slate Tiled Floor
As the tiles were exceptionally dirty, I applied a strong dilution of our alkaline cleaner, Tile Doctor Pro Clean, which can be used for both light soil buildup and very heavy soil buildup. After applying the product, I left it to dwell for a healthy period to allow it to break down the thick layers of dirt.
Sealing a Slate Tiled Floor
I was keen to seal the floor the following day, so I installed a fan overnight to speed up the drying process. As many will already know, a tiled floor cannot be sealed until it is completely dry, or else the excess moisture will cloud the sealer.
Upon my return to the property the next morning, I used Tile Doctor High Shine to seal the floor as requested by the customer. This sealer is specifically designed for use on textured natural stone such as Slate, providing a durable, resistant and high shine surface seal. I applied four coats in total.
