Need glue to attach wood veneer to thin wood panels

Need glue to attach wood veneer to thin wood panels

Need glue to attach wood veneer to thin wood panels

(OP)
I glue wood marquetry veneer, .022 thick, to the surface of walnut wood small box tops that is 1/4 thick, and 2 1/2 inches square. I have been using yellow glue.  The lids warp when fully dry, because I assume the water in the glue causes the walnut fibres to expand.  Thus the glue sets with the wood expanded in size.  The veneer is "set" and then, when the water evaporates from the walnut/veneer, the wood contracts.  The glue is already "set", and cant contract.  This causes the lid to warp, making the surface the veneer is on to be concave.  What glue is there available, other than contact cement, that I can use that does not contain water?  Or do you know of a procedure that would prevent the walnut fibres receiving the water in the glue, and expanding as a result?  Would it work to "size" the walnut with an exterior carpenter glue?  Please help, as I am in desperate need of overcoming this problem. I make a large amount of these boxes, and am scrapping far too many of them.  Thanks, Roger

RE: Need glue to attach wood veneer to thin wood panels

Roger,

You are completely right about the moisture in the adhesive causing this problem.  Most waterbased glues (Titebond "aliphatic", Super Titebond "PVA") contain upwards of 50% water to act as the carrier.  If the wood wasn't porous, it wouldn't cause as much of a problem.  Unfortunately that leaves two alternatives.  You can use either a solvent based contact cement, or a hot melt.  The right glue stick will bond this immediately with good results.

I hope I've helped,
