Tip from Joe:
Don't forget a glue roller. It's worth every penny.

In a well ventilated area, thoroughly wash the back side of the copper with water or acetone using a steel wool or synthetic steel wool (Scotch-Brite) pad. Apply TC-20 to the porous substrate with a glue roller or short nap paint roller. Set the copper veneer onto the substrate. If necessary, apply painter's blue tape over the edges of the copper to prevent movement. Clamp the surface for 45 minutes using a flat piece of plywood and plenty of weight on top (books, tools, wood, etc). A vacuum press will also work very nicely.

TC-20 is not suitable for exterior projects.

Allow an additional 90 minutes of curing before machining. Not for use with copper containing zinc or copper which has been treated with a protective or gloss-enhancing chemical or process.

What else will TC-20 work with?
I've had reports that this adhesive will bond wood veneer to raw aluminum and acrylic plastics but I have not tested this out yet. If you try it, please let me know.

What should I do if I just bonded some of your copper veneer to a piece of plywood and it's not sticking after 90 minutes?
This adhesive needs a full 24 hours to cure. If you "test" the panel before that time and try removing the copper, you will find the bond has not cured. It absolutely must have 24 hours before you judge the quality of the bond. I've yet to hear of a failure after the 24 hour bond time.
