Titebond® WeatherMaster™ ULTIMATE MP Textured Sealant is an elastic moisture curing sealant with a textured consistency perfect for use in most construction materials, including asphalt, stucco, concrete, mortar, wood, brick and stone. It will even adhere to challenging surfaces like Kynar 500® PVD and vehicles, such as tractor-trailers, as well as windows, doors, siding, curtain walls, roofs, fiberglass and vinyl siding. It can be extruded in extreme temperatures (down to 0° F/ -18° C) with a unique polyether chemistry to eliminate out-gassing on green concrete and protect against discoloration when exposed to ultraviolet light. It will expand and contract with the changes in weather and temperature and will not crack. ULTIMATE MP Textured Sealant contains no solvents or isocyanates and is VOC-compliant. If touch-ups are necessary, it may be painted with a water-based (latex-based) paint one hour after application.

    • Method of Application: Cartridge/caulking gun
    • 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 prevent adhesion. It is the sole responsibility of the user to thoroughly test any proposed use with all substrates to determine project suitability. To ensure neat sealant lines, mask areas adjacent to joints.
