How To Install

HydraShell Supreme SA features a split-back release film that peels off for easy installation. The clean, easy-to-handle, self-adhering application makes installation quick and efficient.

Step 1

Tack/secure the end of the roll with a nail. Unroll the membrane 3 to 6 feet.

Step 2

Carefully remove the upper release liner, align the membrane, and continue to peel the release liner from the membrane. Stop frequently to press the membrane in place with heavy hand or roller pressure.

Step 3

When finished with the desired length, repeat the process at the starting point by removing the remaining poly release film and pressing the membrane in place with heavy hand or roller pressure. Side laps (horizontal laps) must be a minimum of 3 inches and end laps a minimum of 6 inches.
