These vinyl decals are meant for wall applications only. Heavily textured walls are not recommended as they may damage the vinyl during installation. Avoid heavily uneven surfaces as well as plaster, raw concrete, unfinished wood, wallpaper, brick, or stucco. They are also not recommended for cinder block walls or paneling. We also do not recommend applying your wall quotes or decals to freshly painted walls or areas that are exposed to high temperatures or environmental wear. Visit our FAQ page for more information.
