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)

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

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

Good stuff, There's definitely a learning curve, but that's on me. Using between thin fiberglass sheets (Boston Whaler resto) I appreciate it's ability to maintain some density even when allowed to expand freely, without deforming the skin.

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

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.

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.

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 repairsCons: can be messy to work withWould I recommend? Yes—solid option for concrete and foundation work

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

Meet expectations.

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

Works extremely well!

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

l expension de ce produit est ridiculement petite, innaceptable
