Professional-grade sealing tape with high-tack acrylic adhesive for difficult-to-stick surfaces. UV-resistant, waterproof, temperature-resistant from -40°F to 176°F. 4 rolls per case, 12 in x 75 ft each.
3M™ Sealing Tape 8777 is a premium translucent sealing tape engineered specifically for difficult-to-stick surfaces, including damp and moisture-prone areas. This self-adhered tape features a proprietary film backing combined with high-tack acrylic adhesive, delivering reliable sealing performance on surfaces where traditional tapes fail. The tape is available on a convenient split liner that enables fast, accurate application with minimal waste and precise positioning.
This professional-grade sealing tape is UV-resistant for up to 12 months and features an adhesive that will not melt or stain when exposed to high temperatures, making it ideal for both exterior and interior applications. The waterproof membrane creates an effective moisture barrier, while the tough yet thin and conformable backing resists punctures and tears during application while fitting conveniently into corners and tight spaces. The aggressive acrylic pressure-sensitive adhesive maintains superior adhesion across a wide temperature range from -40°F to 176°F, ensuring reliable performance in extreme conditions.
Perfect for deck joist and header board sealing, window and door opening seals, and other demanding construction applications, 3M™ Sealing Tape 8777 combines durability with ease of use. Each case contains 4 rolls of 12-inch width tape with 75-foot length per roll, providing ample coverage for both small repairs and large-scale construction projects. This product is compatible with many building sealants and is designed for industrial and occupational use by trained professionals.
