Application Instructions

1. Surface Preparation: Ensure all surfaces are clean, dry, and free from dust, grease, and other contaminants. Remove any loose or flaking surface coatings, old sealant, and mastic joints.
2. Priming: Porous surfaces may require priming. Test a small area first.
3. Application: Cut the tip of the cartridge, taking care not to damage the thread. Attach the nozzle and cut at a 45° angle to the desired bead size. Apply using a standard sealant gun, maintaining an even pressure and consistent angle.
4. Smoothing: Smooth down within 10 minutes of application using a spatula or piece of wood wetted with a soap and water solution. For a neat finish, masking tape can be applied to both sides of the joint and removed within 5 minutes of application.
