relief cut, but place adhesive
where the membrane folds
over itself to ensure a water-
durable connection. Overlap
butt joints by 1-1/29 and
use the mastic to ensure a
water-durable connection.
Apply adhesive to the vertical
and horizontal legs of the butt
joint. Work the material care-
fully into position and smooth
out, using the flat edge of
the trowel.
