Had this conversation with a guy at work the other day. I was talking about a bunch of tile I have to set eventually, and he piped in about using liquid nails instead of thinset mortar. I'd never heard of it before, but I'm not sure I see a big downside other then the cost. It would probably remain more flexible then mortar, no worry about mixing it right, using it before it cooks off, very minimal cleanup, etc. It would certainly cost more - but probably not significant for smaller jobs. Chipping out and replacing a broken tile could be an even bigger PITA I guess. I've set plenty of tile before - I have no problem working with mortar. Just wondering if anybody has any comments/experience/suggestions on the idea?
