Bathroom Floor Grout Revamp Isleworth

Revamping Grout in an Isleworth Bathroom with a White Tile Doctor Grout Colourant

The Grout on this bathroom floor at a property in Isleworth was in quite a state and was bringing down the overall look of the bathroom. Ceramic tiles are impermeable so very easy to clean so although I would include giving them a thorough clean, I knew it was the grout that would be the most work.

Bathroom Floor Grout Before Restoration Isleworth

After taking a look, I realised that the staining was so deep cleaning wouldn’t give a consistent look so immediately recommended colouring the grout and replacing the tired silicone sealant all of which could be done in a day. Happy with my suggestion I worked out a quote which was accepted and a date agreed.

Deep Cleaning Grout on a Ceramic Tiled Floor


To start the grout was given a scrub using pre-treat cleaner, it’s comes in a spray bottle so it’s very easy to apply. It’s an effective ready-to-use cleaner designed to clean and lightly etch the grout to achieve a superior bond with the colourant which would come next.

As part of the cleaning, I also gave the ceramic tiles a light scrub with Tile Doctor Pro-Clean which is an alkaline Tile and Grout cleaning solution. The bathroom floor was a small area so this work was carried out by hand using a scrubbing brush. Once done the floor was rinsed with water and the soiling extracted with a wet vacuum until as dry as possible.

The next step was to strip out the silicone sealant between the tile and verticals; this is done using a sharp knife until all the remnants of silicone are removed. With that completed work moved on to colouring using a bottle of Tile Doctor Grout Colourant in White. The colourant is painted onto the grout line using a small brush and any excess wiped off the tile afterwards. Two coats of colourant were needed to achieve a consistent appearance.

To finish fresh anti-mould silicone sealant in White was applied between the floor tiles and vertical surfaces.

Bathroom Floor Grout After Restoration Isleworth

Once complete the bathroom looked fresh and crisp giving the impression of a new installation. For aftercare cleaning I like to recommend Tile Doctor Neutral Tile Cleaner along with a two-chamber mop and bucket that can keep clean and dirty water separate.
