DAP Weldwood Original Contact Cement

Preparation:

1. Stir Contact Cement thoroughly with a standard paint paddle or stirring stick.
2. Pre-fit all parts before applying Contact Cement.
3. Both surfaces must be clean, dry and free of foreign material. Painted or non-porous surfaces must be roughened before adhesive is applied.
4. The temperature of air, adhesive and surfaces should be above 65°F (18°C) for a minimum of 24 hours before and after application to ensure proper drying and bond strength.

Application:

1. Using a paint brush, short nap roller or finishing trowel, apply an even coat of adhesive to both surfaces.
2. Allow both surfaces to dry 15 to 20 minutes (dependent on temperature and humidity). Dry Contact Cement will feel tacky and appear glossy.
3. Align surfaces into exact position and press together, moving from one end to the other to avoid bubbles.
4. Once surfaces are joined, a minimum of 25 lbs. per square inch of pressure should be evenly applied to surface starting in center and working out to edges.
5. No clamping required. Contact Cement bonds permanently when sufficient pressure is applied and reaches maximum holding strength in 7 days
6. Trimming or finishing operations may be performed immediately after bonding. Allow at least 72 hours of curing before exposing bonded assemblies to direct sunlight or temperatures over 150°F (66°C).
