Titebond® WeatherMasterTM ULTIMATE MP Sealant is specifically formulated to outperform all other sealant technologies, including VOC solvent, silicones, tripolymers, and urethanes.
It offers unbeatable adhesion to aluminum, painted metal, PVC, concrete, wood, masonry, vinyl, glass, plastic, steel, asphalt roofing and most common building materials such as wall panels, siding, flashing, and sheet metal including KynarTM and HylarTM 5000 coated metal panels.
Titebond® WeatherMaster ULTIMATE MP Sealant adheres well to damp surfaces and provides a weather-tight seal against water, wind, dust and dirt.

If touch-ups are necessary, it may be painted* with a water-based (latex-based) paint two hours after application. This sealant extrudes well in cold weather conditions (down to 0°F/-18°C) and is UV-resistant, making it the ideal choice for exterior applications. It will expand and contract with the changes in weather and temperature and will not crack. ULTIMATE MP Sealant contains no solvents or isocyanates and is VOC-compliant.

Air, sealant and surface temperature should be above 0°F(-18°C).WeatherMaster ULTIMATE MP Sealant is intended for exterior use. If light colors are used indoors, sealant must be painted. Painting may occur two hours 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 wipe with solvents. Once sealant is dry to the touch and does not transfer, remove masking tape. If joint depth exceeds 1/2", use backing material. Not designed for continuous submersion or use below the waterline. Store unused product in dry location below 75°F (24°C). Do not apply ULTIMATE MP Translucent to polycarbonate due to solvent cracking.
