The surface must be fully cured & structurally stable . Make sure the surface is dry, clean and free from contaminants such as dirt, dust, loose material, oils and chemicals.

TIP: For cleanest possible result and a perfectly straight line sealant application, especially in hard-to-reach places, use masking tape. Apply the tape covering both sides of the line to be sealed, and then remove the tape before the sealant is dry.



1. Application

a. Use a standard caulking gun to dispense the sealant.

Note: The use of a caulking gun ensures even distribution for a professional finish.

TIP: Hold the sealant gun at an angle of 45° while pulling the gun towards yourself. Find the right working speed to properly fill the necessary gaps.

b. Ensure the sealant is in contact with both sides of joints and gaps. Use foam backer rods to establish good bonding at the sides and to control the depth of the sealant.

2. Finishing Remove excess sealant and tool with flat knife. Depending on humidity & temperature, applied sealant is touch dry after 30 minutes. Note: Protect from water exposure for at least 4 hours after application.
