1.

Mechanically secure loose penetrations at the interior of the wall before detailing. Install non-gassing polyethylene foam backer rod backed by spray foam around electrical fixtures, conduit or plumbing to form a back dam.

2.
Apply FastFlash or Joint & Seam Filler around the wall penetration at a minimum thickness of 12 mils (FastFlash) or 20 mils (Joint & seam Filler). Use a dry trowel or spatula to tool and seal the joint. Create a joint profile that directs bulk water away from the opening.

3.

Provide a minimum 1" overlap of FastFlash or Joint & Seam Filler with the selected PROSOCO primary air and water-resistive barrier.
