necessary to caulk the join if the overlap is 12" or more*. Insert DMX

Washers™ along the overlap every 8" inches (20 cm).

If you are joining two pieces of membrane horizontally, install the lower

piece first. The upper piece must cover the top of the lower membrane,

overlapping it by at least 6 inches* (15 cm), apply a full bead of sealant

to the join if the membrane is being applied as a wall waterproofing*.

Install DMX Washers™ every 6 inches* (15 cm) along the overlap.
