Titebond Weathermaster 10 oz. Gray Polymer Sealant is a premium-grade, superior polymer formula designed to provide adhesion to a variety of common building materials including wood, vinyl siding, masonry, PVC, and fiber-cement siding and trim. This versatile sealant is for outdoor applications such as sealing windows, doors, shutters, exterior trim, siding, gutters, and vents. It performs well even in low temperatures, remains permanently flexible without cracking, and resists UV damage. The VOC-compliant formula will not shrink and can adhere to wet or damp surfaces, making it highly reliable for different weather conditions. For results, apply the sealant to clean surfaces of debris, and use a caulking gun to create a bead of 1/4" to 3/8". Cleanup is simple with acetone or isopropyl alcohol before curing; once cured, excess material can be trimmed away easily. Model Number: 46721
