Liquid Urethane Rigid Pour Marine Foam 2 Lb Density - Closed Cell (2.5 Gallon Kit)

This stuff is great! I installed a 2 person whirlpool tub in my Master Bath. The tub has to be supported by at least 2# foam. I also used it to fill in some cavities around some heating ducts. This is the ticket. It mixes easily, expands without cracking drywall, and sets hard as a brick. I have purchased this twice, and plan to buy more. Beware - it jumps - it gets on everything if you are not careful....and it's sticky - clean up is hard. Be prepared to throw away mixing cups, stir sticks, and any clothes you get it on!!!

Used this to fill in some air gaps around some projects of mine. I mixed according to directions and had enough time to lay the foam. While the foam is expanding, you can also tilt the project (where possible) to get the foam to adhere to the walls. Hardens nicely, however, if you go to cut/trim it down, you will get lots of foam particles everywhere.Good overall.

I use pour foam for molds and this works exactly as I needed

I bought this because I was replacing a deck on an old fiberglass boat. This worked great. Follow the instructions mix it up and poor it quickly.

We use it to foam tires. Works like a charm

Works great, simple, but i thought i was buying a soft foam. This is rigid

This product worked as expected, uniformly filling approximately 10 cubic feet @ 90ºF, and providing a great sculpting media for large scale plug building.

Perfect works great.Perfect for my boat application.
