A customer contacted us regarding a Ceramic Tiled Shower Cubicle problem they had with their house in Glasgow. The grout and mastic sealant had started to discolour and there was staining on both from mould which is quite a common problem in modern houses and our busy lifestyles and insulated homes with insufficient ventilation.
Cleaning Ceramic Tile and Grout
We started by giving the tiles a good scrub with Tile Doctor Pro-Clean then focusing on the grout we thoroughly scrubbed it with more Pro-Clean and a stiff grout brush, this process did well to clean up the tile and grout but unfortunately the grout had become too badly stained to be satisfactory. It’s a fact that the top layer of grout is actually porous and this is where the staining from the dyes in shampoos etc. will occur.
The next step was to cut out all the old and mouldy mastic and seal around the shower using a sharp knife taking care not to scratch the shower tray.
To overcome the stained grout issue we gave the whole of the grout two coats of white Grout Colourant which is a very effective treatment that forms an epoxy barrier over the gout protecting it from future staining. Normally when you do this we recommend using a pre-treater product that provides a chemical key that allows the colourant to latch on to, in this case however I was happy that the scrubbing we gave the grout with Pro-Clean would have the same effect. The tiles were then wiped down using Tile Doctor Neutral Cleaner to remove any excess colourant from the tiles and give them a finishing shine.
The last step was to Shower was finished off by applying new silicone sealant to the areas that were removed. The final result was a shower cubicle that looked recently installed.
