This super-strength extreme double sided tape is built for true heavy duty mounting—when you need more than “sticky,” you need a bond that feels welded on. The upgraded 3-layer all-acrylic adhesive delivers long-lasting hold, while the closed-cell foam core helps create a tight seal for waterproof performance and reliable use indoor/outdoor, even in harsh conditions from -40°F to 250°F. To tackle “hard-to-stick” materials, it includes adhesion promoters that boost grip on low-energy surfaces like PP/PE plastics, rubber, silicone, matte/textured and painted finishes. Works on many common materials including plastic, metal, wood, glass, brick, ceramic, and stone. Simply cut into strips, peel and stick—no drilling or tools needed. It reaches maximum bond in about 72 hours, and gets stronger over time. Not recommended for wallpaper, delicate surfaces, Teflon, or other non-stick materials.
