The photograph below is of a Ceramic Tiled Shower Cubicle at a house in the lovely village of Walshaw which is part of the Metropolitan Borough of Bury, near Tottington and Bury. Most of the grout had darkened and some of the grout had cracked and had fallen out, the silicone seal at the bottom of the shower had gone mouldy in places and would also need replacing.
I find mould is a common problem in bathrooms and more prevalent in smaller bathrooms where the hot air and steam are unable to dissipate as easily creating the ideal environment for mould to grow. The solution is improved ventilation; alternatively you can keep on top of the situation by regular cleaning with Tile Doctor Duo Clean.
Tile and Grout Cleaning
To tackle this installation I started by spraying the Tile and Grout down with Tile Doctor Duo-Clean, let it soak in for about ten minutes and then scrubbed it in by hand with a stiff brush followed by rinsing with water. This made a big improvement however there were still areas where the grout was still showing evidence of staining and would need a grout colourant applied to make it look like new again.
Next step however was to rake out the areas of grout that had crumbled and replace with new. Being a Tile Doctor this is something we are very familiar with and once the grout had dried I was able to move onto colouring.
Normally I would recommend using a Grout Colourant Pre-Treater before colouring however in this case I felt the scrub down I gave the grout with Duo-Clean would prepare the grout sufficiently and further preparation would not be necessary. The colourant is painted on using a small brush over the grout and any excess wiped off the ceramic tiles. The process makes a big difference to the look of a shower and the colourant provides a barrier over the grout making it easier to clean in future.
Last step was to strip out the silicone sealant between the shower wall and tray and replace with a new mould resistant sealant in white.
