Application Guidelines

Application Temperature:
Above 40°F (4°C). If used under 40°F, tooling may be required.
Service Temperature Range:
-75°F to 300°F
Method of Application:
Cartridge/caulking gun
Tooling Time:
For a 1/4" bead, approximately 10 - 15 minutes, depending on temperature and humidity.
Application Directions:
1. Surfaces must be clean and free of any material that may prevent adequate adhesion. 2. Remove nozzle, cut tip of the nub and puncture inner foil seal. 3. Screw nozzle onto cartridge and cut tip on slant to appropriate bead size and place in cartridge gun. 4. Allow sealant to flow smoothly over backer rod into the joint. No tooling is required. It is the sole responsibility of the user to thoroughly test any proposed use with all substrates to determine project suitability.
Painting:
May occur one hour after application with an exterior, water-based (latex-based) paint. For other paint types, a compatibility test is recommended.
Cleanup:
Clean uncured material with acetone or isopropyl alcohol. After curing, excess sealant must be cut or scraped away. Follow solvent vendor's precautions when using solvents.

Limitations:
Not designed for continuous submersion or use below the waterline. Air, sealant and surface temperature should be above 40°F. If used under 40°F, tooling may be required. Do not apply if rain is expected within one hour. Cure time is dependent upon ambient conditions including temperature and humidity. Painting may occur one hour after application with an exterior, water-based (latex-based) paint. For other paint types, a compatibility test is recommended. It is highly recommended to use backing material. Allow sealant to cure 48 hours before exposing to traffic. For best results, store in a dry location at or below 75°F.
