I have been trying to learn how to apply veneer on a small project. Based on
some early discussions in rec.woodworking I was using the technique of
applying PVA glue to both surfaces, let it dry then place the veneer on the
substrate and use an iron to heat the veneer and activate the glue. When I
did this the veneer started cracking from the heat and also pulled apart at
the butt joints (I needed three panels of veneer to span the small table
top). Any suggestion on how to apply veneer?
I just used something called Better bond found at this sight
http://www.veneersupplies.com/ worked great.
I am also new to veneering this sight was wealth of information
A. Your iron on problem was most likely caused by too hot an iron for too
long and/or trying to apply it too soon after you applied the glue to it.
The glue added a LOT of water to the veneer which means the veneer was much
enlarged...it needs to return to its former size before ironing on; it is
going to take a couple of days at least. I've not done a lot of iron on
veneering but I've had better results with the procedure by applying glue
ONLY to the substrate. That way the veneer doesn't curl up into a tube :)
B. Cold pressing is better IMO. The biggest problem with that is getting
sufficient pressure in the center. The conventional answer is a veneer
press or shaped cauls but I think this would work well (haven't tried it but
will one day)...

3"-4" thick foam rubber oversized
cover sheet (brown wrapping paper, etc)

Clamping the plywood to the substrate along the edges compresses the foam,
foam applies a relatively even pressure over all the substrate.

I assume you are taping these pieces together with veneer tape?
I like to use Unibond 800. It's NOT water based, so the veneer won't
curl when the glue is applied. Unibond also has a long open time, so
you don't have to scramble to get all the clamps tight befor ethe glue
starts to set.
I usually buy it at:
I also bought a veneering DVD from this site. He goes over the basics
in great detail and it was really helpful.
