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)

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

Great products exactly what I ordered and needed

This is a great product and a good value for the money. It expands well when thoroughly mixed and sets very hard once cured. It worked well for foundation washouts, concrete pads, and walkways. Definitely wear gloves during application—it can get messy. Pros: expands well, cures very hard, good value, great for repairs Cons: can be messy to work with Would I recommend? Yes—solid option for concrete and foundation work

Works well. Not good for foam filling tires though. It breaks down after a short time.

I use this often. Very strong, hard. Can add more. Plenty of time to mix with wand and pour if access to area is open/accessible. Best to set a cover over, plastic sheet between, and trap it right where you want it. Use lot of weight to hold until set because will “ push out/distort” just put what you need

No where near the expansion I was hoping for

Replaced foam under floorboards in my boat and this product worked extremely well.

Measure equal parts into 2 containers. Pour into a 3rd container and stir for 20 seconds then pour into what you want filled. I used this in an aluminum sectional flag pole to make it rigid for use as an antenna mast. Worth noting, when this starts expanding it does it FAST if it’s hot outside. 1 1/2 fluid oz. of each part (3 oz. total) expanded to fill 13 inches of a 2 inch hollow pole and this stuff is hard as concrete but super lightweight. Wear gloves as you don’t want to get any on you and it does heat up when expanding and curing. It only takes 5 minutes or less for full expansion. Expands probably 10x the volume when mixed properly. This is great stuff.

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
