I just put in a tub surround, and when I try to seal it this happens: Last time it just "billowed" like the stuff on the right hand side, now it's actually dripping down

Nope, it was dry as a bone. Last night it started to billow when I had a shower, then it got like that while my girlfriend was showering

Professor Shark posted:Nope, it was dry as a bone. How long between sealing and having the shower? You should leave it at least 24 hours, I'd say even more, like 48. Otherwise it hasn't set properly and the water gets in.

48 No baths either, we showered at her parents. One thing I read online was that the tub should be filled with hot water when you seal... I didn't do that.

Professor Shark posted:48 I've never tried that. Sounds like you know what you're doing though, so I'll assume you've cleared away any old sealant and cleaned the area you want to seal with white vinegar or something. After that I'm not sure what your problem is. Sealant hasn't gone off? Is the sealant still wet after 48 hours?

The weight of a tub full of water and/or you will cause the level of the tub to sink slightly, which is enough to make a seal stretch and split or break. Looking at the wavy edge on the seal on the right of that picture it seems to be what's happening here. You need to fill the tub, let it settle a bit and then seal it. e: I'd suggest cold water rather than hot though as condensation from the steam will cause similar problems to sealing a wet surface. kecske fucked around with this message at 17:48 on Aug 9, 2015 |

My girlfriend's father disagrees, but I'm going to try taking off the old stuff and filling the tub with water + a 30lb dumbbell on a towel sometime this week after cleaning with acetone and leaving a fan on it for a few hours.

Professor Shark posted:48 You do want to fill it to let it settle, as mentioned above. In older tubs, cast-iron cores were very common, which were then usually coated with porcelain. If your tub is one of those, fill it with hot water. Otherwise, cold will do fine. EDIT: use a magnet to test. A painfully obvious note, but the question has come up more than once.

I think this is the start of a story that I've heard in ER a few times. You were checking the shower and were only wearing a towel, to stop your clothes getting wet, right?

I've been grouting tub unfilled and having cracking grout issues and this might in fact be a brilliant solution.

Did you check the subfloor? Sometimes a bad subfloor can cause this. Even weighting down the tub can won't help, cause the subfloor will give even more later.

That is some weird schitt. It looks as if it doesn't even stick to the tub. I assume it looks right when you applied it but screws up after using the tub. Check the calk to see if it works with a porcelain lined tub.
