Effectively air seals and insulates homes and buildings while enhancing R-Value, and providing Class A fire resistance. The patent-pending technology offers a wide broadcast spray pattern similar to two-component systems, but in an easy to use one-component solution that can be applied in a wide temperature range of 40°F to 120°F. Ideal for rim joists, touch-ups or smaller repairs and projects. Applicator Included.

This product sprayed out of the can in clumps - not a wide spray as claimed. The aerosol only lasted for half of the can. The price of it was four times the cost of a regular can in the hardware store and did not function properly leaving me with nothing but a mess. This was not easy to use.

Make sure to but an extra bottle as your first practice one. After you get the hang of it and the spray down it's easy to use. We used it in a well house to do all the edges on the roof and the gaps the big bottle missed. It did exactly what we needed to do. There's a lot in the can and if you do it right it can go a long way.

Don’t waste your money. This product doesn’t work as advertised.Not enough propellant to spray it accurately and it doesn’t stick on vertical surfaces. Tried it on Rim Joists not successful at all

Ok at first, then the sealant started spraying air rather than foam while I still had 1/2 can left. Attempted to use after a couple hours, however, when I returned the can (on its own) had released extreme amount. Might consider doubling up as 1/2 can is wasted.

Spraying the can upside down made it difficult to use for our application as there was not really any room for the can. Didn't stick to the board as well as it showed it should. Wont know exactly how well it worked until outside temps get below 10 degrees for a 3-5 days. Hopefully the pipe thats near that space will not freeze again

I have a cedar 4"x4" window sill that was beginning to get soft in a couple places. We were getting ready to have our house painted. I cleaned out all the rotted wood and used this to fill in the holes. I shot it in, let it set until morning and shaved off the access. Worked like a charm. Didn't have to pay to have the beam replaced. $20 well spent. Wear gloves with this stuff. Worked for what I needed.

Coverage seems a little over estimated, but then again I held the can upright for the first few pulls of the trigger. Read the directions. Greatstuff also has a version that seems to adhere a little better. Neither is as good as the 2 part tank systems and mix gun. If doing anything other than small repairs, go that route.

I thought this would be great for insulating rim joist cavities. Nope. I experienced a number of problems.1) The can is too long. I understand the can must be held upside down. The problem is, when you do that, there isn't enough space to get the can in a position cover the bottom corner of the cavity. It hits the floor above before you can get the right angle.2) One can could only cover three cavities. With a little practice, you could probably get it a little thinner and maybe cover four. But, at the cost of this can at about $20-25, it's not going to be cheaper than buying a Froth Pack if you're doing an entire house.3) The foam didn't stick. I cleaned the cavities with a vacuum before spraying. The foam sort of slipped or peeled away from the surface. I think it'd be better to just use a fine point foam to seal the cracks and then use foam sheets or fiberglass insulation to finish the job.
