Make sure the adhesive is placed 24 hours in advance at the location where you intend to use it. The temperature of the environment is important for the level of adhesion. This way, the leather, adhesive, and wall will have the same ambient temperature.
Apply the adhesive to the wall using a notched trowel. Allow the adhesive to air dry until it becomes transparent, taking into account the amount applied, the absorbency of the surface, ambient temperature, and humidity. This process will take approximately 10 minutes, depending on the substrate.
Afterward, you can install the leather wall tiles. Rub or roll the tiles without applying tension.
