WeatherMaster Sealant

Titebond® WeatherMaster™ Sealant has been specifically formulated to outperform all other sealant technologies, including silicones, tripolymers and urethanes. This superior polymer formula provides the best possible performance on siding, windows, doors and vents. In addition to offering permanent flexibility, it provides unbeatable adhesion to wood, masonry, PVC, fiber cement, siding/trim and most common building materials. WeatherMaster Sealant is available in over 175 colors, all of which match today’s popular siding colors, regardless of material or manufacturer. If touch-ups are necessary, it may be painted with a water-based (latex-based) paint one hour after application.* It is weather-resistant, extrudes in extreme weather conditions and is UV-resistant, making it the ideal choice for exterior applications. Safety is not compromised, as this sealant contains no solvents or isocyanates and is VOC-compliant. *Titebond WeatherMaster - Translucent (#44011) is not paintable.

Tooling Time For a 1/4" bead, approximately 10-15 minutes, depending on temperature and humidity.

Working Surfaces Surfaces must be cleaned down to the original substrate and free from any material that may deter adhesion. It is the sole responsibility of the user to thoroughly test any proposed use with all substrates to determine project suitability prior to using product on your application.

Cleanup Uncured materials may be cleaned with isopropyl alcohol. After curing, excess sealant must be cut or scraped away. Follow solvent vendor’s precautions when using solvents.

Limitations

Air, sealant and surface temperature should be above 0°F(-18°C). WeatherMaster is intended for exterior use. If used indoors, sealant must be painted*. Painting may occur one hour after application with a water-based (latex-based) paint. For other paint types, a compatibility test is recommended. To ensure neat sealant lines, mask areas adjacent to joints. Always apply sealant in a bead form. Once sealant is applied, do not smear, feather or wipe with solvents. Once sealant is dry to the touch and does not transfer, remove masking tape. If joint depth exceeds 5/16”, use backing material. Not designed for continuous submersion or use below the waterline. Store unused product in dry location at or below 80°F (27°C). For questions, please call our Help Line 1-800-347-4583 or visit us at titebond.com.
