If your wallpaper is not adhering well or peeling off there are a few things that could be causing this:1) There was dust, oils from skin, or dirt on the walls that was not thoroughly wiped off prior to installation. 2) The walls are too textured.3) The wall was recently painted and was not given enough time to outgas properly.4) Your paint is Low-VOC or has additives in it that prevent adhesion of the wallpaper.5) You installed the wallpaper on matte or latex paint. We recommend purchasing a sample first to test our wallpaper on your walls as our wallpaper is made to order and non refundable
