Application Instructions

1. Ensure all surfaces are clean, dry, and free from dust and grease.

3. Cut the nozzle at a 45° angle to the desired bead size and screw onto the cartridge.
4. Apply using a standard sealant gun.
5. Smooth down within 20 minutes of application using a wetted spatula, piece of wood, or wetted finger. Avoid saturating the surface as this will delay drying.

Limitations

• Not for use in conjunction with bitumen or asphalt.
• Do not attempt to abrade when cured.
• Do not overpaint until a surface skin has formed.
• Certain poor-quality paints (especially certain vinyl matts) have very little movement in the dry film. It is possible for the dry paint film to crack if movement is excessive.

Cleaning of Tools
