Gluing Metal to Wood
From contributor J:
Epoxy. Just be sure the surfaces are clean and scuff them up with some coarse paper.
From contributor T:
I'd recommend MDF for the substrate, or else kerf the plywood to accommodate differences in expansion between the materials.
From contributor O:
Most general contact cements will work.
From contributor A:
True poly adhesive/caulks typically have the best adhesion and toughness for bonding different materials. These are not PUR.
The best is 3M 5200. It is a marine or black white poly adhesive/caulk. It has been renowned in the marine community for over 30 years. The claim to fame is that it will hold a lead keel on a boat hull with no fasteners.
PL and Sikaflex make a similar product that is sold at Home Depot. They are both very good as well, but nothing beats 5200.
From contributor K:
Surprised nobody has mentioned good old construction adhesive. Done this quite a few times using PL400 with good results.
From contributor I:
I would like to glue copper sheet to a gluable backer (melamine on particleboard). I've gotten different opinions from suppliers. Any ideas?
From contributor O:
PL construction adhesives will glue virtually anything to anything and I have had some interesting accidental glue-ups to prove it.
From contributor U:
I have a client who wants to completely cover a lot of hollow metal door and window frames with hardwood trim to achieve a more traditional appearance. What would be the best adhesive assuming I don't want to use mechanical fasteners that would have to be countersunk and plugged?
From Jeff Pitcher, forum technical advisor:
Assuming they can clamp it, I'd suggest a reactive PUR.
