We used a latex primer, but with the thickness of the vinyl, and the type of paste, I'm sure you're right about the gasses. I'll research the pastes you suggested and try a different one next time.
Thanks for such a quick response...I was wondering if I should take action now, or wait--and on your advice I'll tackle the larger ones now and wait on the smaller ones. This mural is huge, and I know that we laid it down almost perfectly. So I can't afford to spend several more hours trying to poke holes in the thing! We had a spot where the wall may have been irregular...but the rest of them sprang up overnight and look fairly large.
I've heard of a "holenpoker" (sp?) but I think I'll be able to use a small exacto knife with success...as long as I don't have to make big slits in the thing (!) Or I'll could bring some sewing pins, but I'm not sure those are going to be tough enough to perforate it easily.
Well, about the adhesive, that's just me pre-emptively worrying about the edges/seams of this mural coming loose. When I last checked on it, it looked alright, but I'm already nervous about it and would like to be prepared to fix it.
I suppose I'll have short life if I keep this up, eh?
