This request came from a client who lives in the Newcastle district of Jesmond who was unhappy with the appearance of their Textured Porcelain floor tiles. The problem was that the Porcelain Tiles were grouted in whilst the underfloor heating was switched on. This resulted in the grout drying out quicker than expected and the tiler struggled to get the excess grout off the tiles. To rectify the problem, the tiler tried to get the dried grout off with acid, but it didn’t work, and the floor was left looking dark and dull. Unable to rectify the problem the client was left with a disappointing pale floor and had searched around the internet for a solution. Normally grout smears like these (aka Grout Haze) can be removed with an acidic product and Tile Doctor sell Grout Clean-up specially for this purpose. However, some grouts contain acid resistant polymers which need to broken down first. Fortunately, we have a solution for everything tile related and the system we use does not affect the main grout lines only the excess grout. I called in to do a site visit and having surveyed the problem I was confident it could resolved, I gave them a price for the work and agreed a date to return to do the job. My first task was to spray the tiles with Tile Doctor Remove and Go, this was left to soak into the tile for around ten minutes before being scrubbed in. Remove and Go is a coatings remover that is safe to use on tile and grout; normally we use it to remove old sealers but in this case I applied it to break down the polymers. To work the product into the tile I use a buffing machine fitted with a black scrubbing pad, the mechanical advantage this gives makes the job a lot quicker. Then the slurry generated is rinsed off with water and removed with a wet vacuum. The floor was then left to dry for 30 minutes. We were then able to remove the excess grout which was done by applying Tile Doctor Grout Clean-Up which I mentioned earlier. The process was the same, i.e. using the buffing machine and a wet vacuum to scrub the floor and extract the soil. The floor was rinsed with water to remove any trace of the products used and dried as much as possible using the wet vacuum. The underfloor heating really helped at this point to dry out the floor. Once the floor was fully dry including the grout lines a single thin coat of Tile Doctor Colour Grow sealer was applied. The tiles were textured porcelain, so the dirt gets trapped into the textured surface if it is not sealed. We usually find one coat of Tile Doctor Colour Grow is more than enough for this, anything that hadn’t soaked in after three to five minutes was then polished off with clean dry cloths. The client was very happy with the floor and pleased that the excess grout had been cleaned up and the floor looked as it should. Before leaving I recommended the use a pH Neutral tile cleaner for general cleaning such as Tile Doctor Neutral Tile Cleaner. There is no point sealing the tiles only to have it stripped off later with the use of a bleach based cleaner. Raf Barrett Tyneside Tile Doctor
