I'll make a note of what you said.Sounds like an open bag that has been around a while. I have been told that sometimes the hardeners separate out in the bag.Not sure if that is true or not but I have had the same thing happen to me with old open bags.
Brand new bag, I got for this job. I hardly ever save that kind of stuff. I usually mix whole bags. So nothing to save.jb4211 said:Which sucks moisture out of the air and makes your situation even more bizarre. Was it a new bag? Could it have been a bad mix?
