2lb Polyurethane Pour Foam

Durable

Even the 2lb is strong and durable when fully cured.

Great product

I won't be draining the water out of the kayak anytime soon. It sets up fast, so be ready to pour and make sure everything is sealed. I didn't notice much weight increase either. Overall it was great to seal up compartments and pouring small batches in every nook and cranny helped not deform my kayak.

Great foam, Competitively priced too.
