Fiberglass Supply Depot 2 Lb Density Expanding Pour Foam, 2 Part Polyurethane Closed Cell Liquid Foam for Boat and Dock Flotation, Soundproofing, Filling Voids, and Insulation (1 Gallon Kit)

arrived a day late and the packaging was crushed so I would say whoever loaded it or possibly the driver handled the package very poorly! The foam product is awesome easy to use works very well I will definitely buy again

I wanted to try this foam for setting fence posts instead of buying the stuff at the home improvement stores. Compared to the Home Improvement store post foam this foam is a little lighter weight and not as hard but still seems to do the job and it is, or was, quite a bit cheaper than the store foam. I don’t know if I would recommend it for building a deck but a residential fence would be fine. Mixing is easy enough, I got a couple silicone measuring/mixing cups and a silicone stirring sticks so I could reuse them once the foam hardened.

Great product

Magnificent. I had a sewer vent inside of a wall cavity that was leaking sewer gas inside the concrete slab. Faced with $5000 of work, I instead mixed a cup of each of these and poured it into the cavity. The closed-cell foam blocks sewer gas better than concrete. It worked beautifully! The next day, I decided to fix my tippy mailbox. Instead of mixing a bunch of concrete, I poured in a half-cup of this. Job done. The only thing unclear is that you have to add B to A, not the other way around. (Or maybe it is the other way around. Read the instructions.) The only thing that's annoying is that A and B have different densities so I have to mix it by volume, not weight. I'm probably too careful with that.

It was good stuff and it works fast! I almost didn’t have time to put it where I wanted it before it started to expand. It does get a little hot on the fingers so wear protection. But it was super easy to use just mix the two together and be fast!!

Works

Bought this because our truck camper has a habit of moving around in the bed of my truck. When we got to Florida Keys we centered the camper and filled trash bags with this stuff. It worked great. 1500 miles later and the camper hasn't moved. The only thing I would have done different was I would use heavier trash bags next time.

It works fine but the cells were much larger than the total boat foam. Ide recommend just buying the total boat 2lb foam.

Fait très bien le travail

Easy to pour

I used this kit to fill a 4" x 20' conduit containing plumbing lines. We were well prepared and the expanding foam worked excellently

Good customer service

Worked as advertised, nothing negative to say about it
