No need to do extra waterproof layer. Save your time and money. * Thickened Aluminum Foil: Thickened aluminum foil insulates fire effectively, also resists melting and deforming during transportation or after long time use, keeping construction from mess and maintains sealing result more than 30 years. * UV Resistant Surface: The grid aluminum surface is designed specifically for outdoor exposure and can efficiently reflect strong sunlight. Comparably cool down the working surface. Instruction for use: 1. (Important) Make sure the construction surface is dry and clean. 2. Remove the release film and expose the adhesive. 3. Stick the tape onto a clean surface. 4. Press the tape to clean any air bubbles.

Review: ممتازة
Review: Did not work at all. - I had a small leak in a garden watering system pipe that fed a water tank. The leak was in a joint and caused by the adhesive not being properly applied when the pipes were joined. I tried to use this tape to seal the leak, but it failed. I do not recommend this product. They claim it will fix leaks exactly like this, but it does not work.
