Prepare the wall by removing old wallpapers. Scrub the wall clean of any mold or mildew. Seal all cracks, crevices and nail holes using a vinyl sealant. Sand it down smooth.
Coat with a layer of acrylic or latex primer to protect walls from moisture seepage.
Dip the Easy-Walls wallpaper in water to activate the pre-adhesive on the back. Paste the first strip straight and perfectly vertical with the use of a plumb line or level.
Activate and paste remaining strips all over the wall. Let the wallpaper dry overnight.
