Speed up your woodworking projects, improve the quality of glue connections, and make your project look better with these tips for gluing wood.
Dozens of glues claim to work well on wood and a variety of other materials, but regular wood glue is still the best wood glue for raw wood-to-wood joinery. Most wood glues are a type of polyvinyl acetate (PVA). Also sometimes called carpenter’s glue, wood glue is formulated to penetrate wood fibers, making glue joints that are stronger than the wood itself.
How long does wood glue last?
You may have heard that PVA glue goes bad after freezing or sitting around for a long time, but the truth is that it might still be OK. Try stirring it with a stick to mix all the glue particles (don’t just shake it). If it’s a little thick, add some water—up to 5 percent. If glue flows freely from the bottle and feels slippery between your fingers—not stringy or clumpy—it’s probably OK to use. But if in doubt, throw it out. It’s not worth taking the chance.
