Stretch the tape to at least double its normal length. Apply it tight on the surface and overlap it tight around itself.

To serve the best purpose for standard electrical applications wrap 3 time with 100% overlapping.

For high pressure leaks (e.g. sealing of pipes) the tape should be stretched very tight and several layers should be used. Depending on the leak and pipe material the tape can withstand a pressure of 12 bar max. Please use max. 4 layers with approx. 100mm tape on both sides of the damaged pipe.

Due to the self-fusing process, after applying the tape on itself, a permanent bond is created. Therefore, the tape can be used once.

Please be aware: Xtreme Condition is not compatible with drinking water
