It is crucial that the bio-jel™ and bio-film™ are applied to a clean dry surface.

The bio-adhesive™ is capable of remaining bonded to the skin while sweating, but any moisture present during application will compromise the performance of the product. This is true of sweat, hair gel, hair wax, sun block, water, lubricants or moisturisers. These should be removed before application.

When the bio-film™ is applied to the skin the bio-adhesive™ reaches its maximum bond strength to the skin between five and fifteen minutes later.

A good time to apply Impact is in the dressing room while togging out. While Impact has been designed to be worn by itself it can be worn under a scrum cap or tape.
