Not a bad thing, but tender and if you don't mix 100 percent you'll end up with either sticky mush or crumbly mush. If it heals properly, it's decent, but it can break or tear easily. It also has a very odd setup time and never gets to the point where it's operational. Essentially, it's super watery or hard, no semi-sticky time. Handling it during construction will also destroy it. I would only use this to fill something where it will settle.
