First post here...been finding lots of good information here (thanks, google!) but stuck on one thing.

I'm replacing some drywall window jambs (aluminum windows--mold and moisture damage on the drywall from years of condensation).

Got myself some vinyl j-bead (reveal type) to butt up against the window frames, but it doesn't seem to look right. I have 1/2" drywall and 1/2" j-bead, but the bead looks a little too big...it doesn't fit tight on the end of the drywall (1/16" gap or so). Should it fit tightly? I don't think I can get a clean edge with the way it's fitting now.

I've confirmed it's the right size...1/2" is printed right on the bead. I'm not trying to fit it into a tapered end. I was thinking I could squish the two sides togeth a little closer if I heated it up with a heat gun, but I'm concerned it might splay out again later after a few weeks of afternoon sun.

Or maybe I just got a bad batch?

Thanks in advance for any advice.

You've got the right idea to solve the problem. Sounds like you say, a bad batch. The plastic likely will have enough "memory" that even if your idea works initially, it will not work long term. I'd look elsewhere for another batch of bead or just live with what you've got. A bead of quality latex caulk will render the gap unnoticeable.......

It sounds you might be using the tapered edge of the drywall to put into the j bead. Try using a drywall piece without the taper.

OP mentioned he's not using tapered edge. I've run across the same thing with plastic bead before. Metal doesn't seem to have this problem, but not an option in this situation due to moisture issue....
