How to glue wood
Dozens of glues claim to work well on wood and a variety of other materials. But regular wood glue is the best wood glue for raw wood-to-wood joinery. Most wood glues are a type of polyvinyl acetate (PVA wood glue). Also sometimes called carpenter’s glue, wood glue is formulated to penetrate wood fibres, making glue joints that are stronger than the wood itself.
Yellow exterior glue (sometimes grey)
Yellow exterior glue is used for outdoor projects but not continuous submersion. It will be labelled water resistant or exterior.
White and yellow interior glue
White and yellow interior glue is the most common, workhorse wood glue, but it’s not for outdoor use.
Liquid hide glue
Use it for furniture repair; very long open time for assembly – up to 30 minutes. Requires a long curing time.
Use it when you need a completely waterproof glue. Also glues metal and some plastics. Long open time for assembly – up to 15 minutes; curing time: up to five hours.
Use it when you need to fill gaps and for great strength. Comes in two parts that must be mixed just before using. Epoxy will glue most materials, and it’s waterproof. Won’t wash off your skin – or anything else.
