A common problem with bathroom and shower cubicle tiles is the appearance of mould on the tile, grout and silicone which if not tackled on a regular basis will spread and threaten to severely damage the appearance of the tiles, along with the silicone. This problem is usually due to inadequate ventilation however the good news is that with early intervention with Tile Doctor Mould Away spray the problem can be reversed.
The two photos below show a bad case of this very problem at a property in Northampton, where you can see that the grout and silicone sealant had become black with mould.
Cleaning and Repairing Damaged Shower Cubicle Grout
Firstly, I decided to cut out the damaged grout with a hand held disc cutter and remove all the silicone at the base of the shower. To treat the less invasive mould in the rest of the cubicle I sprayed it with Tile Doctor Mould Away, which is specifically designed to remove mould from silicone and grout.
I sprayed the product onto the affected areas and left it to dwell for five minutes, before scrubbing it in with a stiff grout brush, resulting in a good clean. The area was then rinsed with plain water. Finally, I replaced the grout and the silicone that I had removed earlier with a flexible grout and a white silicone, both of which include a mould inhibitor.
The photographs above show the end result. The customer was very happy with her refreshed tiles, and left the following feedback:
“Phil was brilliant – both when he came to look at the job and then when he returned to actually make the grout repairs. Most importantly he explained what was (and wasn’t possible) and did exactly what he said he would do. My shower area now looks brilliant and I’m no longer showering in fear of the tiles falling off the wall! Honest, clean, timely and totally professional. A tremendous job well done. Thank you.”
I left the customer with a bottle of Tile Doctor Aqua Pro to aid with regular cleaning. If used once or twice a week, this product will help maintain the condition of the grout. I also advised the customer that it is good practice to rinse the tiles down with plain water using the shower head after each shower to remove any soapy residue which can slowly discolour and stain grout over time.
