Contour Wall Graphics are simple to install and do not require a professional installer. Simply remove dirt, debris or moisture from the desired area, peel off the release liner, lay the Contour graphic flat on the surface and compress by hand or with a roller, making sure all edges are completely adhered to make it ready for immediate use. If the surface is oily, it may need to be power washed with a commercial degreaser before application to insure a successful installation. The high performance pressure sensitive adhesive provides superior holding strength to ensure the Contour wall graphic looks its best. It can be applied at temperatures at or above freezing.
