All In One Surface Treatment

Neox insulation foam can be used to protect so many surfaces around your home from leaks to preventing pest. This high-density polyurethane foam can cover up to 20 square feet and it includes a nozzle so you don't have the need of a spray gun. “GREAT” means less expense out of your pocket. It's quick curing and it outperforms other products that use fiberglass and cellulose that has a tendency not to bond as well as Neox with its superior thermal airtight barrier.

works as it should , need a better clip for tips

the foam is what it claims to be and works as it should. only reason it got 4 stars is because only 1 of the 2 nozzles was with the can , 1 for walls and 1 for ceilings, and I was wanting to use it on both. but instead I just stuck with walls and I'll use a different one for the ceiling section. otherwise great foam
