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.

Perfect sized product for a test we were doing before ordering larger quantities. Easy mixing instructions and a decent work time of 1.5 minutes. Super strong once it has set up.

Great and versatile product. I have used it for body casting and reinforcing faux rocks for photography props.

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.

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.

would buy again ,if needed.

When l received the item and opened the box the plastic lid was cracked. l've used this stuff in the past and often the lids end up breaking even when l'm trying to be careful. l end up having to repair the lids or cover the bottle with something else. The lids are too brittle and too thin. The foam its self works okay.

work great, form hard insulation layer in 5 min
