There are two different types of adhesive you can use to install the backsplash panels. The first type is to use a notched trowel (1/4″ x 1/4″ x 3/4″) and apply the adhesive directly to the backsplash. ACP, the manufacturer of Fasade, recommends using Loctite PL Premium. The second type of adhesive that can be used is a High-Bond Double-Sided Tape. This is applied in strips to the wall or the back of the panel. See our Fasade Backsplash Installation Guide for more information.
