OK, we did 500 SqFt floor & none of it set up. I went a scaped off what I could today.The only thing I can think of for failure, is we had a 1.5g kit & a 3 g kit. 1.5 g & 3g kit have same container of A & B units. I was aware of this potential problem, & thought I kept track during mixing. (not that much to keep track of), but that's the only conclusion I can find. Could it be mislabeling? Ok, scraped most off but thin film remains. Anyone have an idea how to remove this film, for future epoxy?
