Waterproof tape is a flexible, adhesive material designed to seal out water and moisture on a variety of surfaces. It is commonly made from rubber, butyl, silicone, or bitumen, and is used for repairs on roofs, pipes, windows, and other leak-prone areas. Most waterproof tapes are UV-resistant, mold-resistant, and suitable for both indoor and outdoor use. Some types can withstand high temperatures, though most are not paintable. Its strong, weatherproof bond makes it ideal for both emergency fixes and long-term sealing solutions.
