## Description

Smooth-On’s FOAM-iT! Series are two-component water blown rigid foams that are versatile and easy to use. FOAM-iT! products are available in 3lb., 4 lb., 5 lb., 8 lb., 10 lb.,15 lb. or 26 lb. per cubic foot densities. Parts A and B are measured and mixed in equal amounts by volume. The mixture is then poured into a mold or other form (apply release agent if necessary). The mixture will expand many times original volume (depending on which FOAM-iT! product you are using) and develop a uniform cell structure. FOAM-IT! 3 is tack-free in about 4 - 6.5 minutes, developing handling strength in 20 minutes and full cure in 2 hours.

### ⭐⭐⭐⭐ MOTHER's BEWARE!!
*by  on Reviewed in the United States November 2, 2025*

I see all kinds of reviews with mothers talking about making "squishes" with this product. Mother's BEWARE! When you mix this product together, it is an exothermic chemical reaction and it produces heat and TOXIC fumes. You may not smell them, but the fumes produced are toxic. Your children may not get sick now, but those chemicals are ingested in the lungs, and years down the road may result in not good. Do Not use this product in the vicinity of your Children unless they are wearing aspirators.

### ⭐⭐⭐⭐⭐ Fun product for making squishys
*by  on Reviewed in the United States July 20, 2020*

My child, supervised, loves making her own squishys!! Product works fast and is fun to try different things and shapes out with. Humidity and temps play a HUGE roll in the processing of the product just so you know
