Installation instructions

Before applying the Hatch Cover Tape clean the surface to which it is to be applied thoroughly and make sure that the hatch cover is free of any salt from the sea-spray.

The surface must be dry before tape application.

In cold weather conditions use a torch to heat up the tape to achieve a better adhesive performance. The flame should be applied to the black surface after removing the release liner. Be careful not to use the torch in a fire danger areas.

Immediately after heating apply pressure to stick the tape onto the surface before the tape cools. This which will ensure optimum adhesion.
