Tub Caulking
A number of years ago we had our bathroom redone and they did an excellent job of getting it done. We noticed that the tub caulk started to separate. I removed it all around, replaced it and a few months later it started to separate from the wall again. One of my coworkers suggested I fill the tub up with water to weigh it down and then recaulk the tub. This worked for a while then it happened yet again. Does anyone have any other suggestions? Thanks in advance!

Your problem is moisture. When re-caulking a tub/wall juncture and after the old caulk is cleaned out of the crevasse,:wink: the area must be allowed to thoroughly dry. Water naturally gets behind the caulk and sits behind the caulk and that is normal. But when new fresh caulk is installed there cannot be any moisture in the crevasse or the fresh caulk doesn't cure properly. Use a fan and let it sit for a few hours and dry.:)

That is by far the most logical thing I've heard and so simple too! Should I still add water to the tub to weigh it down though?

Bud hit the nail on the head (as usual):thumbsup:
It's got to be clean and dry before putting new caulk in. If the old caulk was a silicone base, it's impossible to get it all off, but get absolutely as much as you can. Then go back with another silicone based caulk. I've never found anything that will stick on top of where silicone has been- except another silicone. When you get silicone off-it may look like you got it all but you didn't. Be prepared to spend much more time cleaning the old stuff off, than putting the new on.
I use a razor blade and try to get all the old stuff off, then wipe it down with alcohol and let dry over night with a fan or heater blowing on it before caulking again.
Once re-caulked, l let mine dry a minimum of 24 hours before introducing any type of moisture into the room. It's critical that the new caulk be cured properly before getting it wet. Give it time. The best and easiest kind of caulk i have found is Polyseamseal Ultra. You can get it at Lowes. There may be better out there, but i like it.

You know what? Some things cause me to laugh my butt off when they keep appearing and this is one of those things. Filling a tub with water to caulk it is by far one of the stupidest things I have ever heard of.

Only a cheap plastic trailer-house tub could benefit from that technique - MAYBE.

HELL NO don't fill the tub. You are trying to keep things dry for God's sake. You will do your best caulking if you are in the tub not reaching over the sucker full of water. THAT'S JUST STUPID!

I'll definitely keep an eye out for that stuff in Lowes, I'm always in there! It's funny about the water in the tub, I never really got it. I mean, my reared in there caulking it would still make it weighed down. I'll definitely spend a lot of time removing it and then drying it out for a day or so. All excellent suggestions and I do appreciate it!
