caulking trim before painting


I am putting up a bunch of trim and will be painting. The walls are out of square and some of the joints aren't perfect. I believe I can use some caulk on these to fill the joints and then paint? Is there a certain kind of caulk that is better suited for this task or just use a basic latex caulk? Thanks for any help on caulking trim.

The siliconized is better but basic latex caulk will do fine inside. It's best to prime before you caulk.

Thanks guys. It is paintable. I thought that I had read that silicone caulk wasn't paintable but I read the tubes in the store and the silicone said it was paintable also. Thanks again

Hey ponch - I'm on a "you get what you pay for" mission and hoping to help you avoid another stupid mistake I made in being too cheap....stay away from the low end DAP (or similar $1 ish price point) paintable caulk or you'll have to redo everything after the high percentage of water in this stuff dries and it cracks up a storm. Pay up for the $5+ GE (or similar) paintable caulk - so worth it.

You want Siliconized Elastomeric Latex. I use DAP Dynaflex 230 and have been happy with it. White Lighting / Sherwin Williams caulk is also reportedly quite good. (SW owns White Lighting.)

I am carrying on a one-man boycott of GE caulk after a horrible experience with their "lifetime guarantee" goopy, nasty, bathtub caulk that mildewed after only a week.

Most caulks will do that if you don't let it dry overnight before painting it.

Nope - I'm not letting DAP off the hook on this. I let it dry overnight (and then some) before painting. It's simple chemistry - the higher the water content, the more the caulk will shrink/crack. The cheaper caulks have the highest water content since water is a cheap filler.

I'll second not using a cheap caulk. I bought regular ol DAP stuff (cheap) and will have to recaulk all the trim in our den (crown, trim around doors and windows, chair rail, etc). The stuff I used looked okay at first, but it has shrunk considerably and now needs to be redone. Had I known better I would have used a higher end caulk.

I also made a mistake in our bathroom when caulking the wainscotting and tub - I used stuff that has adhesive in it (on accident) and that turned out to be a hot mess. All my nail holes are now yellow and I need to scrape that crap off the wainscotting and repaint it.

Not a fun project at all.

Some is, some is not.
