Renovating Mouldy Grout in Greater Manchester

An elderly couple from the Greater Manchester town of Eccles were in touch recently regarding their Ceramic Tiled Bathroom, they had a big problem with mould build-up due to a broken extractor fan and wanted it removing. Mould grows in humid conditions and with the extractor fan out of action it soon started to spread. If you have been reading my blog, you will have seen some of the bathroom transformations we have completed over the years, so I was confident we could resolve the problem for them and paid them a visit to take a look.

You can see from the photographs that the tiles were in good physical condition, but the grout and silicone mastic sealant was stained with shampoo dyes and mould spots, the worst part however was the ceiling which was covered in mould growth. I ran a test clean on the bathroom wall grout and ceiling which went very well so we quickly agreed on a date to clean the whole bathroom.

They say you should always start at the top and work down so my first task was to treat the mouldy bathroom ceiling with Tile Doctor Duo Clean which although marketed for use on grout it worked just as well on paint to remove the mould. When done with ceiling I moved on to the wall tiles spraying on Duo Clean, letting it soak in for ten minutes, working it in to the grout with a stiff brush and then rinsing off with water.

With four walls of tile and grout and a ceiling to clean the overall cleaning process took two days to complete and at the end of the second day I turned my attention to the silicone sealant. Taking care not to scratch the bathtub I carefully stripped out the silicone in-between the tile and bath with a sharp knife. Duo Clean works on silicone as well but you do need to catch it early so often the easiest thing to do is to replace it rather than clean it. I replaced the silicone with a good quality mould and bacteria resistant silicone.

When I returned on the next day I carried on with the Top/Down approach by turning my attention back to the ceiling which I painted with a white moisture resistant emulsion paint.

With the ceiling freshly painted I then took another look at the grout which although clean was not a perfect white anymore and looked dull and uninviting. We do find this can happen with grout, especially if it isn’t the subject of a regular cleaning regime. There is a remedy though and what we find works well in these cases is to recolour the grout with an epoxy-based Grout Colourant which not only rejuvenates the grout it also protects it for years to come.

Grout Colouring Bathroom Wall Tiles

There are ten colours to choose from in the Tile Doctor range of Grout Colourant however in this case I felt the best outcome would be to use a White colourant to match the tiles and restore the original look of the bathroom.

The colourant is easily applied directly to the grout and in this case, I applied two coats with the aid of a small brush making sure to remove any excess that comes into contact with the tile. After applying the colourant, the bathroom transformation was complete, and it looked like a new installation.

It was a lot of work however I was really happy with the outcome and so were the clients who even left me a nice tip. The last thing to sort out is the extractor fan, however they will need a different tradesman for that job.
