• Cut tube nozzle to desired angle and thickness. Pierce inner foil seal. Place into standard caulking gun.
• Hold at a 45° angle and apply by pushing sealant ahead of the nozzle to achieve a smooth seal.
• Smooth caulk using a wet finger or a damp cloth for a clean, neat appearance. Wipe away excess caulk with a damp cloth before sealant skins. Complete tooling within 20 minutes.
• Sealant normally “skins over” in 5 minutes, dries to touch in 1 hour, and cures and in 24 hours. Allow 7 to 14 days for full cure.
• Allow a minimum of a 2 hour cure time before painting with latex or oil-based paints. The length of time for a full cure is dependent upon the thickness of the application and additional factors such as temperature and humidity.
