Question
We are currently working on a large project that requires veneer to be applied after fabrication (post-veneered). We are using the dreaded contact adhesive. We veneer the panel, flush trim, and sand, and the next day the veneer has expanded 1/8"-1/4" beyond the extent of the fixtures. We have rolled/pressed the veneer extremely well. This problem is not isolated to one fabricator. 7 custom fabricators have had this problem. The species if pecan. We have had problems with pecan before. We are also laying up ash currently, and are having no problems whatsoever. The veneer is wood on wood. The shop is not climate controlled. Any help?

From John Van Brussel, forum technical advisor:
I assume you are using a water based contact. If you are using a j-roller for pressure, stop. You need to use a shop built scraper or a veneer hammer. J-rollers do not give enough pressure for veneer. You may want to try FSV, which is a fast tack PVA which is applied similarly to a contact, except that you only have to coat the core.
