Hi everyone, I'm trying to seal in cigarette odors in a basement before painting. I heard Zinsser BIN is the way to go. I was able to pick up the Sherwin Williams branded shellac (the white pigmented shellac, the real deal, not synthetic) during the 40% discount weekend. Ended up being cheaper that BIN. Is it just as good or should I not take the chance and go ahead and get the BIN? I heard it's the same product but hoping I can hear from someone's first hand experience. Goal is to seal in the odors.
Thanks!
Thanks!
