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.
