It's Oracals version of air egress. Had some spots that just would not stay down. Wall was painted with Kilz approximately 2 weeks ago.
This is mostly true. I have had some luck with flat or eggshell...problem is many new gloss paints have that anti-stain additive that makes it tricky. One trick we have learned is to take alcohol to the paint with a rag, and then stick your graphic on.decals do not like flat paint, they need something to grip on
