DEKS Blue Line EPDM Washer Installation Guide

DEKS Blue Line EPDM Washer Installation Guide

BUILDING IT RIGHT TO MAKE IT WATERTIGHT

DEKS Blue Line EPDM provide an excellent waterproof seal— even under the most severe weather conditions— if properly installed.

The trick is not to overdrive or underdrive the screws.

If the screw is not tightened enough, moisture leaks around the washer. An overtightened screw squishes the washer too thin, which can also result in leaks.

Important Tip:

Replace worn sockets immediately if they cause the screw to wobble during installation. Crookedly driven screws can cause water leaks.
