Pur Black was developed especially for outdoor use.
The black color blends into the surrounding environment and never looks dirty. It will seal and stop the passage of air, gases, water, dust, fibers, and sound into a building. Sealing air leaks also reduces the number of places than insects can use to enter a house.
Pur Black is a rigid, low expanding, closed-cell foam that is applied with the foam gun we sell. One 750 ml canister will produce 2,820 cubic inches of cured foam, making 1,200 linear feet of 1/2" bead. It is tack-free in ten minutes and trimmable in thirty minutes. Note that an application gun is not provided with each can of foam, and must be purchased seperately (see related products).
