Ye Gods, this has to be one of the worst jobs...
Despite having managed to ignore SWMBO's bleating about the nasty black mould on the silicone seal in the shower for, well, years? I now have no option but to rip it out and redo it, since we have 'damp-patch-on-hall-ceiling syndrom' and I can only suspect the seal is the culprit.
So I'm currently hacking away at it using a combination of Stanley knife, a bare Stanley knife blade, and scraper (which includes a Stanley blade). It's leaving bits behind and in the gap between tile and shower tray; and I can't help feeling that where I've slashed at the stuff it will make future leaks more likely if I can't get 100% of it out. I'm also nicking and scratching the acrylic surface of the shower tray which isn't great.
Any wonderful tips on how to do this job properly? Are the silcone-eater-type solvents any better than they were 10 years ago when I last tried them (useless)?
Do I need to get every last trace of silicone off, or will it be OK providig all the black s**te has gone and I'm back to cleam, solid substrate before applying new stuff.
And what about tips to avoid mould growth in the future? I've bought a sanitary grade mould-resistant silicone to replace it with - but I'm pretty sure that's what I used originally :(
