Titebond WeatherMaster Metal Roof Sealant

Titebond WeatherMaster Metal Roof Sealant is an elastomeric polymer sealant for sealing and repairing metal roofs. It adheres to all metals, including Kynar coated metals, aluminum, galvanized steel and copper, and to most common building materials.

It can be extruded in extreme temperatures. It stays flexible, does not shrink, adheres to wet and damp surfaces, and resists dust and dirt. It is mold and mildew resistant, UV resistant and compatible with all types of foam. Joint movement capability is ±50%. It is paintable after 1 hour, except the Translucent version, which is not paintable.

1. Surfaces must be clean and free of any material that may prevent adequate adhesion.
2. Remove the nozzle, cut the tip of the nub and puncture the inner foil seal.
3. Screw the nozzle onto the cartridge and cut the tip on a slant for a 1/4 in. to 3/8 in. bead. Place the cartridge in a professional cartridge gun.
4. Force the sealant into the clean joint. Always apply sealant in bead form. Mask areas adjacent to joints for neat sealant lines.
5. Remove the masking tape once the sealant is dry to the touch and does not transfer.

No tooling is required. Do not tool and do not smear. Cleanup of uncured white, clear and colors: acetone or isopropyl alcohol. Cleanup of uncured translucent: mineral spirits. Cured excess sealant must be cut or scraped away.
