Description
Stop leaks fast and seal out water, air, and moisture with Flex Tape MAX, the super-strong waterproof repair tape built for the toughest fixes. A thick, flexible rubberized backing grabs onto almost any surface and conforms to cracks, seams, and curves, giving you an instant watertight bond that even works underwater. Reach for the wide 4-inch by 25-foot roll whenever you need to patch, seal, or hold something fast, indoors or out, wet or dry.
Key Features
- Super-strong waterproof seal: bonds on contact to stop drips, leaks, and drafts in seconds.
- Thick rubberized backing: conforms to smooth, rough, curved, and uneven surfaces for a tight, flexible hold.
- Works wet or dry: grips in the rain, through moisture, and even underwater.
- Gets stronger over time: press firmly and the adhesive builds an even tighter bond.
- UV-resistant and VOC-free: stands up to sun, weather, and extreme temperatures indoors and out.
- Big 4" x 25' roll: covers more in one pass; cut to size with scissors or a utility knife.
Applications
Patch plumbing leaks, seal gutters, downspouts, and flashing, and bond repairs on boats, autos, RVs, and pools. Flex Tape MAX holds on PVC, metal, copper, aluminum, wood, glass, fiberglass, rubber, concrete, EPDM roofs, and more, making it a fast fix for roofs, tarps, vent boots, hoses, and shower or bath surfaces. Clean and dry the surface, round the patch corners, and press from the center out for the strongest seal.
Choose Your Color
