how long did you let the joint compound cure ? never used it for anything but sheetrocking but if you let it cure long enough it gets nice and hard and will last |

It cured about 10 hours. I put it on, went to sleep an hour later, slept 8 hours, and an hour after I woke up started putting the ground cover on. It should be given 24 hours to cure. Maybe more since with this you'll probably have some spots that are thicker than on a wall. One spot I put it on fairly thick and it was still a little soft, and cracking a little. But yes if you let it dry all the way its about as solid as plaster. I remember a sheetrocking job and trying to get that stuff broken out of a bucket after 4 days sitting to dry. A few whacks on a rod of rebar into it busted out a 3 inch thick disk of it quite nicely :)
