MarkR Posted July 11, 2008 Share Posted July 11, 2008 Hi chaps. I recently discovered a leak in the tiles between the bath and the wall. To fix it, I stripped all the silicon out and half fillled the bath (to simulate load so the silicon didn't pull away when we used the bath/shower). Then I dried the entire area with a hairdryer for about half an hour. Resealed and it looked great. Only thing is that now about 2 months later I have serious black mold growing on it. Any ideas on how to do this properly and also some recommendations on silicon that doesn't mold over? Cheers Mark Quote Link to comment Share on other sites More sharing options...
The Raven Posted July 11, 2008 Share Posted July 11, 2008 O dear, Anti mould silicon B&Q should solve it. Might be worth sitting in the bath to do it bath shouldnt move to much if it does the legs might need adjusting. Quote Link to comment Share on other sites More sharing options...
MarkR Posted July 11, 2008 Author Share Posted July 11, 2008 Strangely I did use Unibond Sealant that said "anti-mold" on the tube. I have noticed that the bath tends to tilt slightly towards the wall which collects water, but it never molded over before so I assumed it would be fine.

Baths has a slight fall on them to allow the water to run away. If you can get the panel off easy might be worth a peek. Quote Link to comment Share on other sites More sharing options...
AlanM Posted July 11, 2008 Share Posted July 11, 2008 I used it on my shower tray seal and it is covered in mould, this is about the third lot of sealant I have tried, all done the same ... Quote Link to comment Share on other sites More sharing options...
MarkR Posted July 11, 2008 Author Share Posted July 11, 2008 Annoying to keep doing as well, as you can't get it wet afterwards for a few days The panel has been sealed in with tiles by the previous owners so will be a right pain to get off, but I think it's coming to that.

Ark Posted July 11, 2008 Share Posted July 11, 2008 Am I the only to wonder why you don't clean the bath more often than once every two months? That would probably solve the problem. Quote Link to comment Share on other sites More sharing options...

I clean it every week, but the mold has taken 2 months to grow from small black flecks to larger patches, even with cleaning. You can't scrup the black flecks off, or the sillicon gets ruined. Edit: that would be scrub Quote Link to comment Share on other sites More sharing options...
Supragal Posted July 11, 2008 Share Posted July 11, 2008 I have the same problem. Anti mould silicone... mouldy... I clean it every week but cleaning doesn't remove it even in early stages!!! Horrible. Quote Link to comment Share on other sites More sharing options...
stevie_b Posted July 11, 2008 Share Posted July 11, 2008 Baths has a slight fall on them to allow the water to run away. The bath top should be level. The fall-off to ensure water runs down the plughole is built in to the floor of the bath. Quote Link to comment Share on other sites More sharing options...

MarkR Posted July 11, 2008 Author Share Posted July 11, 2008 Might be worth a try. My bath is almost level with a tendancy to slope towards the wall at the front near the taps. I might have to open up the side of the bath and adjust the height to correct the slope before redoing the silicon Quote Link to comment Share on other sites More sharing options...
Ark Posted July 11, 2008 Share Posted July 11, 2008 Also, how well ventilated is the room? It may not be direct wetness, but rather the residual humidity after a shower/bath. Quote Link to comment Share on other sites More sharing options...
MarkR Posted July 11, 2008 Author Share Posted July 11, 2008 I have a working extractor fan, but no window although it's a fairly large room. As I said before though, it never got mouldy in the 6 years before I redid the silicon, and now with new stuff in it goes black. Quote Link to comment Share on other sites More sharing options...
