Q&A: Best Glue for Exterior Trim

Three experts answer common questions about the sticky stuff

Q. For gluing exterior wood trim components that will be exposed to the weather, but not submerged under water, what’s best: resorcinol, epoxy, or a polyurethane glue?

A.Any one of these will work, as long as the joint has good wood-to-wood contact. Personally, I think that epoxies and resorcinols have the best outdoor endurance qualities. For those joints that may be a bit loose, epoxy is the best, as it has the best structural and gap-filling qualities.
