Fiberglass Supply Depot 6 Lb. Density Expanding Pour Foam, 2 Part Polyurethane Closed Cell Liquid Foam for Boats, Dock Flotation, Carving, Soundproofing, Filling Voids, and Insulation (1 Gallon Kit)

I used this product to pour through a small hole into an area that an animal was attempting to dig under my deck. It expands pretty rapidly and you need to get it poured as fast as you can after mixing it. You have maybe a 60 second working time before it takes off. It expands very rapidly and voluminously. It filled the area with decently hard cured material. Just don't put it someplace fragile and confined, it will very happily push out thin wood on its way to full expansion. The end material seems acceptably durable. It builds a thin skin on itself and it's not easy to rip apart or dislodge. The resultant material also sticks aggressively to anything, so make sure you are ok with that. Also, don't get the pre-cured material on your hands; it sticks extremely well to human skin and it will be a pain to get off. Overall a great product for filling spaces!

Great for tub repairs.. Injecting under tub floors for support, to lift floors up a bit, prevent tub floor sagging. Also great for injecting into inner tub walls to use as a backer for the rest of your repair once it's hardened. Allows one to continue and complete the repair job in one fell swoop.

Great products exactly what I ordered and needed

Worked great. Easy to mix, poured well, and got into all the holes. I had an hole in the base layer under some concrete that also has pavers on top. The concrete has shifted and no matter how much sand I used to backfill the cracks- the pavers keep shifting as well. I used this, and after a heavy rainy season, the pavers and concrete still have not moved.

This is our go to foam for casting figures from our molds. It is a little expensive, but the 6lb retains awesome detail.

Used this to insulate around a bathtub and it worked great. The foam expanded exactly as expected and provided a solid, supportive fill without over-expanding or creating pressure issues. Once cured, it formed a dense, durable barrier that helps with both insulation and soundproofing. Just be sure to follow the mixing directions carefully and prep your area—it sets fast. Highly recommend for home projects where a strong, stable fill is needed

It worked, expanded and fulled voids. However compared to a leading brand, not even 1/3 the total volume I was able to get from the leading brand. It was still rock hard after expanding, just would have required 2x+ the quantity. For the price if I was doing a small job would have been fine, but for the large volume I was doing wasn’t sufficient.

Just used about two medium solo cups worth on thr 1g kit. Mediocre expansion. Extremely underwhelmed and it was not as dense as other 4 and 6lb foams I have used. There's a reason why its cheaper, its low quality.

Works great for my taxidermy molds Expands roughly 4 times liquid amount and is rock solid ( 6lb )

Works extremely well!

This is good stuff, not soft, squishy foam. Very high density and tough

mixing is important, better mix greater yeild better float. liked the shippers percautions adding insulation for candian weather!!

l expension de ce produit est ridiculement petite, innaceptable
