*Flex Tape is a temporary, emergency repair and is not meant to be a permanent fix.

**Flex Tape may not bond to all hoses.


For maximum adhesion on porous surfaces, using a standard blow dryer will help the adhesives bond with the surface.

Flex Tape’s bond will increase with time and pressure. Continued firm pressure will help increase adhesion.

Once fully bonded, Flex Tape cannot be repositioned.

Flex Tape adhesives may resist bonding to some plasticized or waterproof materials, siliconized, greasy, oily, dirty, or porous surfaces.

Certain fabrics such as canvas, nylon, polyester, synthetics, cotton and some other materials may need up to 24 hours to reach maximum hold.

Both!

Remember to cut your Flex Tape larger than the area of the leak. You do not need to drain the pool prior to applying it.
