Reader Question: Priming Crown Molding

Written by on January 11, 2014 in Ask the Topcoat Team!, Uncategorized with 2 Comments


I have newly installed, 3-piece crown molding system installed (poplar wood). I anticipate movement in the joints as time passes. I’m looking for the best primer to tolerate the movement as well as to cover any poplar issues. The SW Premium Wall and Wood Primer you recommended looks very interesting but I couldn’t find anything about how well it tolerates movement. Can you help me? Thanks.




The SW Wall and Wood will tolerate the movement just fine. Usually, that is not where issues occur. You are more likely to see issues at caulked joints – not so much inside/outside joints, but the parallel joints in your 3 piece configuration. You would have been well served to back prime all of the pieces prior to installation. This is one of the best ways to create dimensional stability. For now, though, yes prime heavily with the W&W, lightly sand at 220, vac, tack, caulk and paint.

    I read your post on caulking three piece crown molding and I find the best caulk on the market right now is called “Big Stretch” from Sashco. I’ve been using it for a few years now and haven’t had any cracking at all. Like the name says it stretches so it expands and contracts with the wood. Hope this helps.
