Instructions for Use
-
Clean the substrate thoroughly; ensure it is dry, free of oil, and free of dust.
-
Apply masking tape on both sides of the joint. If the joint is wide, fill the joint with appropriate backing material.
-
Remove the aluminum seal at the rear of the cartridge, cut open the cartridge, attach the nozzle, cut the nozzle to the required size, and extrude the sealant using a caulking gun.
-
Apply the sealant continuously and evenly, moving smoothly to ensure the joint is fully filled. Avoid applying too quickly to prevent air bubbles or voids.
-
Finish and smooth the joint within 10 minutes after application, then remove the masking tape.
