I have to tile a bathroom wall. I have PLENTY of ceramic tile adhesive (AcrylPro, from Home Depot) left over from a previous tile job about 4years ago. I checked and it looks and feels just like a fresh gallon of the same.
Does anyone have experience with using "old-ish" adhesive?
know the argument of "why take the risk?" but asking for anyone with practical experience using older tile adhesive and whether it holds.
