TAPE ALL SEAMS

» Trim excess trough at seams, keeping overlap so

tape will cover the top of the joist and seams (3G)

» Using Trex® RainEscape® tape, tape ALL seams,

joints and perimeter making sure the ﬂashing is

taped to the trough. (3H)

NOTE: Trex RainEscape Caulk can be used instead of tape,

if preferred. If using caulk, caulk must be applied between

ALL product overlaps and between product and joist on

perimeter of deck. In cases where tape will not stick,

(usually on brick or stucco)

INSTALLING A GUTTER SYSTEM (not included)

» Before installing a gutter system perform a water

test to clean out the system and check for any leaks

» Attach a standard gutter system to collect the

water from the Trex RainEscape downspouts.
