Multifunctional tape, easy to use. The tape is thicker, more viscous, and has a longer service life. Repair wall cracks and use roof for waterproofing. The smooth surface band has high reflectivity and higher thermal insulation. Aluminum foil material is not afraid of scratches, friction resistance and high temperature resistance. Material: aluminum foil + butyl note: 1. Ensure that the construction surface is dry. 2. There should be no impurities on the construction surface, otherwise it will affect the viscosity of the tape. 3. The tape is too narrow to affect the waterproof effect. 4. Can not be used on the back of water, it will fall off. 5. The roof waterproof finds the leak point and does not work. size: Width: 5cm / 10cm Length: 5m Package Included: 1 x tape how to use: Before construction, make sure the surface is clean and dry. Peel off the released film and apply RV roof sealing tape. Press the butyl sealant repeatedly until the tape is completely stuck to the surface. Tools needed (not included in the package): cleaning tools, scissors, trimming tools, gloves. Size: 5cm x 5m / 10cm x 5m These tapes have butyl rubber, a high-tack and pressure-sensitive sealant with tack. They can form an instant seal, prevent water, air or dust from entering, and remain permanently soft. This tape is specially used for occasions that require moisture resistance and chemical resistance, thermal conductivity, flame retardancy, heat and light reflectivity. Do not use with benzene, benzene, vinyl, silicone and other waterproof materials. feature: Resistant to chemicals, heat and weather. High viscosity cold weather adhesive. It has excellent adhesion even at low temperatures. Block moisture and odors. Excellent insulation properties. Water resistant and UV resistant. Due to the strong stickiness, please wear gloves to prevent your hands from sticking. In winter, it is best to use a hair dryer to heat the camper’s roof before installation. After applying it within 24 hours, do not peel it off.
