Without a doubt, yellow woodworking glue has adhered its place in the Woodworker’s Hall of Fame. But for complex joinery, veneer work and bent laminations, there is a better choice.

Urea resin adhesives are an industry standard for veneering. Many, however, require high temperatures for proper bonding, so they aren’t suitable for small shops and individual woodworkers. That’s why my choice is Unibond 800; it’s formulated to provide the same bond quality at room temperature (70°) as those “hot” industrial glues. That makes it an excellent choice for just about any small-shop veneering job.

Why Unibond 800 rather than other cold-press urea resin adhesives for use at room temperature? The others I’ve researched have a higher water content. That could be a problem when veneering. Plus, other urea resins, when the powder is mixed with water, can leave a visible glue line in laminations, depending on your project wood. With Unibond 800, you have the ability to tint the adhesive to match your wood.

When fully cured, Unibond 800 forms rigid glue lines. This eliminates glue “creep,” an unwanted characteristic commonly associated with yellow glue, which forms glue lines that remain flexible.
