Preparation

It's essential to correctly prepare the area for application before starting. Otherwise, you risk not having optimal results. You should clean the surface by removing any contaminants that can hinder the adhesion, including impurities such as dirt, dust, oil, grease, etc.

Application

1. Cut the top of the cartridge, ensuring you do not damage the threaded screw.
2. Cut the top of the nozzle at a 45° angle and screw it onto the top of the cartridge.
3. Place the cartridge into the standard sealant gun/applicator.
4. For perimeter pointing, you should apply an even, continuous pressure along the gap. When bonding two surfaces, you should cover one surface with a zig-zag motion using the silicone and bring them together.
