Instructions for Using the Adhesive

Note: The temperature of the adhesive and the temperature of the surface must be between 20 °C (68 °F) to 38 °C (100 °F). The surface must be smooth, clean, and dry.

1. Clean the surface by wiping the surface with a 50/50 mixture of isopropyl alcohol and water. Allow the surface to dry completely.

2. Remove the protective paper from the seal and press the seal in position.

3. Use a roller or a similar device and apply a minimum of 103 kPa (15 psi) over the entire surface in order to bond the adhesive to the surface.

   Note: Pay special attention to the edges and to the corners in order to ensure that these areas are bonded securely. Avoid conditions that would apply stress to the bond for 24 hours after installation.
