Pool pads, wall foam, and cove molding are used to provide protection for and increase the life of your above ground pool liner. Pool pads provide an important protective layer between a vinyl swimming pool liner and its sand or soil base. Wall foam helps protect your liner from rust and corrosion, and it will improve your pool's heat retention. Cove molding helps eliminate stretching, pulling and tearing at the bottom, and is easier to use than trying to mold your sand.
