Yellow Glues

Yellow glues, also known as P.V.A. (polyvinyl acetate) glues, include the original white glues, and some of the older yellow glues.

The newer yellow glues, such as Tite Bond II are aliphatic resin glues. They are the mainstay of the woodworking industry, in that they are easy to work with, are water soluable, at least until dry, and have great holding power. They also have the advantage of cross-linking, meaning as the water evaporates, a chemical reaction takes place and renders the glue water resistant.

This glue, while not rigid, as is urea resin, it still has it's place in veneering. One significant advantage is that it can be brushed or rolled onto both surfaces, allowed to dry completely, and the be ironed on, with a household iron. This process is reversable for about 24 hours. After that, it's permanent. This feature is a huge advantage when needing to place a laid up veneered panel in it's exact location, prior to it sticking. Unlike contact cement, where once the pieces touch, your unable to move them. Also any bubbles found after glue up can be ironed down, for up to 24 hours. On example of this would be matching table legs from poplar, and then ironing on an exoctic veneer. The process is permanent, and very cost effective.

Clean up can be done with water, and squeeze out at the joints should be left alone until mostly dry, and removed with a putty knife or chisel.
