the product was hard as a rock. it must have been subjected to cold weather or too hot and it is all dried up. we cut open the tube in the middle and had to use a skill saw to do it. It was that hard! I will never buy caulk from internet again.

easy to apply, very workable with putty knife
Top quality stuff
Johnny•July 13, 2016
The foam is a bit easier to apply, but residential grade foams are garbage and commercial foams are much more expensive. For caulk it adheres well and sets quickly.
Great compound

Easy to apply, sandy texture with fibers in it. Cures fast, and keeps its form. Holds to drywall and plastic much better than the smooth rubber silicone type.
