Foam-iT! 5 - Rigid Polyurethane Foam - Gallon Unit

This is much better a product to use than Great Stuff if you are repairing cracks in a fiberglass tub. Offers superior support and hardens quickly. I will definitely order again.

would buy again ,if needed.

Worked great. I was able to make 3 life size skulls out of one box.

My end results were closer to 8 #/cu ft than 5. I was filling a cylinder 26" tall by 2 1/4" diameter. Filled and vented through a 3/8" diameter hole at the top. Maybe the "constrained" expansion played an effect.

Este producto es excelente para todo los artista plásticos y sus creaciones por su peso y su moldeabilidad.

I used this for a science project and it was amazing to see how they kids respond to the expansion. Always do it outside and use gloves.

work great, form hard insulation layer in 5 min

It sets up really rigid. I was expecting it to set up as a softer foam but this is very dense. It was suggested as a tool to work on silicone reborn dolls, mix up a batch, tear it into pieces, and use as a paint applicator. When cut into pieces, it was too firm, and also left a lot of debris behind. And, of course I had to open it to test it out, and so it's not returnable.
