Dirty Grout Problems Resolved

This Ceramic tiled family bathroom with shower was installed at house in Leighton Buzzard and was in need of rejuvenation. You can see from the photograph below that the tiles were in reasonable condition but the grout had become ingrained with dirt which is not unknown as the top layer of grout is porous and will discolour over time if not protected.

Cleaning Ceramic Tile and Grout

The Ceramic tiles and grout were treated using a strong 2:1 dilution of Tile Doctor Pro-Clean mixed 50/50 with Nanotech Ultraclean which combines a highly powerful Tile and Grout cleaning product with tiny abrasive particles. For vertical tiled surfaces I recommend the mixture is decanted into a bottle with a trigger spray attachment which when sprayed onto the wall allows the cleaner to mix with air making it lighter and allowing it to stick better. The solution was then worked in using a stiff scrubbing brush by hand before being rinsed off with water; this process was repeated a number of times until we had managed to clean all the areas and then left to dry.

Sealing Grout

The grout was dried and the sealed with a couple of coats of Tile Doctor Grout Sealer which forms a protective barrier over the porous grout and keeps it looking good for longer. Most sealers can be used on grout (check the label to confirm) but for best results use a spray bottle as mixing the sealer with air improves its ability to stick to a vertical surface.

Changing the colour of Grout

The home owner of this house in Stockbridge had become increasingly unhappy with the state of their ceramic tiled floor and we were asked to come in and give the ceramic tile and grout a thorough deep clean.

Cleaning and Preparing the Tile and Grout

To get the tile and grout clean I applied a dilution of Tile Doctor Pro-Clean and left it to soak in to the surface dirt for a while before scrubbing it with a rotary machine fitted with a black scrubbing pad and also a stiff hand brush along the grout lines. This was then washed down with warm water all of which was removed by a wet Vacuum. This cleaning process was repeated until the tiles were clean and the grout was a good as I could get it. Unfortunately the grout had stained quite badly and we were unable to get a good uniform appearance so it was agreed that we would applying a white Grout Colourant.

Applying Grout Colourant

The grout colourant range sold by Tile Doctor are a huge improvement on those grout pens you will find in DIY stores, they come in a range of colours and form a hard wearing epoxy barrier over the existing grout that looks natural and effectively protects the grout from further staining.

The grout needs to be clean and dry before you apply it so if you’re doing this from scratch make sure you clean the grout first with Pro-Clean or the Pre-Treater product that is available. The grout colourant is then easily applied using a toothbrush, it sounds easy but you have to be very methodical. The colourant dries in about an hour after which it’s worth double checking your work and then removing any excess by applying a little water and running over it with a white pad.

I think you will agree from the photographs the tiles look much cleaner and the change in grout colour makes the floor look that much fresher, it will also be a lot easier to maintain going forward.
