I recently paid a visit to a customer at a house in the town of Preston to restore the colour of the grout in their bathroom which due to years of using strong cleaning products had bleached the grout of any colour. The tiles themselves were not the issue they seemed fine but the grout was looking Tired; we discussed the options and decided the best course of action would be to apply a grout colourant. Two different colours were chosen, white for the shower area and Sandstone for the toilet area.
Colouring Wall Grout
Before applying the grout colourant it’s important to give the grout a deep clean using the Pre-Treater that comes with the kit; the solution is sprayed on and scrubbed in by hand before being rinsed off with water.
Once the grout had dried I started to apply the Grout colour which restores the colour and seals the grout as well, thus making it easier to clean afterwards. Grout colouring is fiddly work but you do get the gratification of an instant change. Once done I called the customer in who was delighted with the new effect as Grout colour if used correctly looks very natural and not as if someone has painted the grout making it look false.
We discussed using the correct type of cleaning product for aftercare as this seemed to be the issue to start with and I recommended Tile Doctor Aqua-Pro as this can be sprayed onto the Tiles and mopped off which is ideal where a small amount of water is required. For regular cleaning Tile Doctor Neutral cleaner was also mentioned as this is diluted into water where more cleaning is needed and mopped onto the floor area.
The before and after photograph below is from a job we did in a Shower Cubicle tiled with small square Mosaic tiles at a house in Bedford. As you can see from the photograph the grout had become stained with mould and mildew growth which had become quite bad and moved onto the surface of the tile.
Cleaning Mosaic Tiles
To resolve the problem a strong dilution of Tile Doctor Pro-Clean was scrubbed into the tile and grout by hand using a stiff brush. It’s best to let the Pro-Clean soak into the tile and grout for ten minutes before working in and to help the solution stick on vertical surfaces it’s best to decant the Pro-Clean into a spray bottle and spray it onto the surface of the tile, this allows it to mix with air making it lighter and enabling it to stick to the surface instead of running off.
The mould and mildew had become quite ingrained and had managed to get quite a foothold in the grout which due to its cementitious nature is actually porous near the surface. As a result the tiles were proving very had to get clean and so working in sections the process was repeated numerous times requiring a lot of physical effort and Pro-Clean before we were happy with the results.
