I was asked by a Chelford homeowner (near Alderley Edge) to renovate their Ceramic Tiled Shower Cubicle which had an unsightly mould problem. They say pictures speak louder than words, so I’ve added some photos on this page which show how the grout and silicone sealant had become discoloured with mould over the ten years since it was installed.

Mould likes damp warm areas and shower cubicles make a perfect habitat for it, grout especially can be a problem due to its cementitious rough surface that mould can get a grip on. In this case the ventilation in the ensuite was inadequate and ideally there should have been an extraction vent over the cubicle itself. My advice in these situations is to leave doors and windows open after showering and to run the cold water afterwards.

Removing Mould from a Ceramic Tiled Shower Cubicle
To renovate the Tile and Grout I sprayed on Tile Doctor Duo-Clean which was left to soak into the grout line for ten minutes before being scrubbed in by hand. The Ceramic tiles cleaned quite easily but the grout had to be scrubbed hard and needed several applications before I was satisfied.
The whole shower needed treating in this fashion and once rinsed and dried I set about stripping out all the old silicone sealant that had also been badly affected by mould. This is done carefully using a sharp knife. I removed the debris and moved onto applying a fresh mould resistant silicone sealant.
Sealing a Ceramic Tiled Shower Cubicle
Last step before leaving was to spray the Ceramic tile and especially the Grout and Silicone with a can of Tile Doctor Aerosol Grout Sealer. This doesn’t last as long as other sealants in the Tile Doctor range but its quick to apply, especially on wall tiles. The sealer ensures water will run straight off the walls into the shower tray and it also makes the shower easier to clean later.

The shower looked like a new installation by the time I had finished, and my client was delighted with the transformation. He was also thankful that I had replaced the silicone, this was something he had considered doing himself but applying it does take practice and you can get yourself into a mess.
