TAPE

Using Trex RainEscape tape, tape all seams, joints

and perimeter making sure the ﬂashing is taped to

the trough. (4B)

NOTE:

Tape works off of compression and must be

pinched between decking and joist to make a tight seal.

NOTE:

The butyl tape should never be put directly on

wood. The trough material or a downspout must be below it.

4. TAPE ALL SEAMS

Trim excess trough at seams,

keeping overlap so tape will cover

the top of the joist and seams. (4A)
