Usage instructions: Aquilim 315, contact cement Directions: Make sure that both surfaces are clean and roughed-up so adhesive can penetrate. Apply adhesive to both surfaces by brushing or spraying and allow to dry completely. Adhesive will turn clear when it’s dry and ready for adhesion; this will take 20-30 minutes depending on humidity. Once adhesive is dry and clear, stick the items to be bonded together and hammer or press. Aquilim GL, rubber cement Directions: The Aquilim GL only needs to be applied to one of the surfaces that will be stuck together. Using a brush or a spray gun, apply adhesive to the back or the roughed-up surface of one piece of leather. While the adhesive is still wet, immediately bond the two surfaces; press or hammer together.
