Are there surfaces for which Blik is NOT recommended?

Absolutely. Don’t even think about applying Blik to strongly textured surfaces like stucco, concrete blocks, unfinished wood or wood products. Not only will Blik not stick but also the rough texture will most likely puncture the decals. Blik will also not adhere to fibrous materials (fabric), not even unpainted canvas. You can apply Blik to paper-based materials but we do not recommend it unless you are interested in a permanent application. Blik is not removable from paper or wallpaper.
