I installed new vinyl windows and now need to caulk them to the drywall of the window boxes on the interior side. What kind of caulk should I use? I've generally been using a nice silicone caulk, but it's not paintable and I anticipate eventually repainting the window boxes. If I use latex caulk, that'll work for repainting, but the old windows used latex caulk and it was brittle as a pretzel stick by the time I removed it.
I was going to say just acrylic latex (aka 'alex'). But since you don't like that or silicone, how about alex + silicone? :) For example:
The product is intended to address the relative weaknesses of each component. It's paintable, but supposed to be more flexible and better able to expand and contract with temp change.
