How to Apply ZenaSeal White

1. Prepare the Surface

Ensure the application surface is clean, dry, and free from oil, tar, dirt, dust, and other contaminants that could interfere with adhesion.

2. Apply Directly From the Can

Hold the can at approximately a 45-degree angle and dispense a continuous bead of silicone measuring 1/16" to 1/8" onto the mating surfaces.

The convenient self-contained dispensing system eliminates the need for a separate caulking gun.

3. Allow the Silicone to Cure

Curing begins immediately after application. The manufacturer specifies approximately 24 hours for full cure, with optimum strength reached after seven days.

Allow adequate curing time before exposing the completed seal to service conditions.
