Polyurethane Glues

Polyurethane glues expand as they cure, filling gaps and creating waterproof bonds in wood, metal, ceramic and stone.  They are excellent for outdoor projects and assemblies exposed to moisture.

What makes polyurethane glue different from other adhesives?
Polyurethane glue reacts with moisture to cure, creating a strong, waterproof bond. Unlike PVA glues, it expands slightly as it sets, filling small gaps and making it suitable for woodworking, construction, and outdoor applications.

On what materials can polyurethane glue be used?
It bonds wood, stone, ceramics, concrete, metals, and many plastics. Its versatility makes it useful for projects where multiple materials need to be joined together.

How do I use polyurethane glue correctly?
Lightly dampen one surface with water to activate curing, apply glue sparingly to the other, and clamp firmly. Wipe away excess foam that squeezes out as it expands during curing. Full strength is usually reached in 24 hours.
