Micah,
Somehow you need to seal the exposed board to counteract the lack of
breathing on the Laval-coated side. If you don't, however the Laval is
adhered, the exposed side will dry more quickly and thus shrink when
the surrounding air is dry, and expand more quickly when the
surrounding air is humid. When I seal wood that I don't want to result
in a plastic look or finish, I rub in, with a soft rag, 2-3 thin
coats of waterbased polyurethane. This can either be polished or
buffed or waxed to get the desired effect.
Good luck,
Vernon Wiering

I'm new to working with exotic hardwoods alone, so this is quite an
adventure I'm having. I am working on developing portfolios out of
Padauk, a gorgeous African hardwood. The inside of the boards are
lined with Laval bookcloth, to emulate suede and to cover and
protect the hinge made also from Laval. The wooden boards are
coated with three coats of polyurethane on both sides of each board.
Naturally, due to the fact that I'm trying to adhere something to
one side and not the other, I'm finding in my prototypes some
significant warping. I've been using a mixture of PVA and methyl
cellulose to aid in working time, however I'm afraid that the
moisture I'm introducing into the wood (since it is, still with the
poly, not completely sealed) is causing my warping. Again, my
knowledge of wood is very limited!!
Are there better adhesives out there for this application? Perhaps
something dry? Perhaps something specifically for wood?
Do I try to seal the wood better or apply extra coats to the outside
of the boards to try to counteract the adhesive pull on the inside?
Am I missing some variable entirely?
Ugh,
