One of the first issues people have with shower rooms is the Silicone needs to be replaced, even a good quality Silicone like Mapei Ultra-seal which is fully waterproof and stain and mould resistant can still succumb to persistent damp issues. In fact it can get so humid in these areas the warm atmosphere is akin to a tropical rain forest.
To avoid the build-up of mould I recommend you rinse the wall tile and silicone down with plain water from the shower head after every shower and then leave the tiles to dry. Open the window and door to let out the warm condensation and after 5 to 10 minutes partly close the window (to the security setting) and then partly close the door, this then normalizes the room temperature thus inhibiting mould spores from blooming, as mould wont start to Spore on a cold room.
The pictures were taken from a shower room at a house a few miles up the road in Kendal where mould had caused a lot of staining to the silicone sealant and to the tile and grout both inside the shower cubicle and in the bathroom itself. There were also a couple of loose tiles around the base of the shower cubicle which needed to be re-fixed.
Cleaning Ceramic Tile and Grout
We started by spraying the tile and grout down with Tile Doctor Pro-Clean which is a strong alkaline cleaner, spraying it on mixes it air which helps it to stick to Vertical surfaces allowing it to get to work on the dirt. We left it to dwell for ten minutes before scrubbing it in by hand using a stiff grout brush; this process certainly improved the grout but unfortunately it had become too badly stained to be satisfactory so we decided to recolour the grout using a white grout colourant.
Once the shower tile was dry the loose tiles were removed and the damp plaster board behind chopped out and replaced. The tiles were then cleaned up, fixed back into position, then grouted and the silicone sealant around the base of the shower cubicle was stripped out and replaced with new.
One to two coats of white colourant were applied to the grout throughout the shower cubicle and shower room in order to get a uniform appearance and this final touch completed the transformation.
The other advantage of these particular colourant products is that they are epoxy based and form a barrier of the grout preventing future staining and making it very easy to clean going forward.
I think you will agree bathroom now looks like it was recently installed.
This job was completed to resolve an Insurance claim for a lady who lives in Warlingham whose bathroom tiles and grout had been damaged from smoke and soot. A building company had attempted to clean the tiles however the lady was not satisfied and told the insurance company it was to be done properly. On inspection the grout was still a bit dirty but I told her it was possible to clean it up, but could not guarantee it would be a uniform finish. I suggested that she could have the grout re-coloured at the same cost and gave her a small demonstration, she was happy with this and contacted the insurance company to get the go ahead; a week later she called me to book it in.
Preparing the Tile and Grout for Re-colouring
When I started the job I went over it with the lady to make sure she was happy with the colour and if there were any other issues. She pointed out that on the border tiles had discoloured and on closer inspection I found that they were a marble tile and the builders had put a topcoat seal on them to make them shiny but because it was the wrong type of seal and it had started to peel.
As a result it was necessary to the sealer as so I put a coat of remove and go on the border tiles and left it to dwell; I also sprayed a solution of Tile Doctor Pro-Clean onto the ceramic wall tiles and scrubbed the tiles and grout before washing then down with warm water. By this time I could then scrub the border tiles in order to remove the old topcoat sealer. I dried the border tiles using my heat gun and the applied a coat of Ultra-Seal; the marble tiles had to be sealed before I could colour the grout.
Applying Grout Colourant
Once everything had been rinsed and the grout had dried I was able to apply the grout colourant using my colour applicator (toothbrush). Its meticulous work so it took a couple of hours to apply and by then I could go round to remove any excess colourant by spraying plain water and scrubbing with a white pad. I use a white pad, because if I used a coloured pad I could transfer the dye from the coloured pad to the seal.
Once I had completed the whole room I checked to make sure everything was okay and found I needed to touch up a couple of areas. I then buffed all the tiles up and cleaned the bath, sink and floor and asked the lady to check it all before putting all my equipment and dust sheets back into the van. The lady was really happy with the result (see comment below) and has asked me to do the same work in her kitchen.
Bill worked continually throughout the day without a break. He was very polite and courteous He was full of knowledge and yes I would use again.
