Review on Gorilla Waterproof Patch & Seal Liquid - Black 16Oz - Ultimate Solution For Quick Fixes (Pack Of 1) by Abdirahman Mensah

I applied this product on concrete sheeting (USG DUROCK) a week ago today and it still has not cured. Remains unhardened and tacky. Have had a fan blowing to increase air circulation for 5 days and very little change. Asked other customers how long it really takes to dry. One said 24 hours. Another said 1 month. Unfortunately I trusted the reviews boasting what a great product this is. I am in the midst of a has to get done tiling job but sounding like I have no choice but to wait a month. Very disappointed! There was was a review that warned that this stuff never dries. If you got the time, or don't care, cuz it does waterproof, then go with it, but if not look for something else. The product is pure silicon never expected a silicon product would take this long to cure.
