do you have to let the stuff fully cure before it goes in water or just harden..its been about 4 days since i put mine on and its hard as a brick the package says tack free in 48 hrs and fully cured in 7 days ?? thanks
If you are in one of the hot states, it won't take the full 7 days to cure. Remember, the manufacturer puts a little "wiggle" room in its specs to account for variation.
