INSTALLATION INSTRUCTIONS
TOOLS: Scissors or utility knife, staple gun,
caulk gun (Fig. 1).
PREP: Read all instructions completely
before beginning. Place a midspan nailer on
the underside of joist to keep them straight.
STEP 1 Installing the
Trex RainEscape downspout
• Cut downspouts along one 12" or 16" side
on score mark based on joist spacing
(Fig. 2).
• Install all downspouts along one rim joists
and/or ledger board; cut out side towards
open deck bay (Fig. 3).
• Downspout should extend 1" into gutter:
cut or extend as necessary.
STEP 2 : Installing the
Trex RainEscape trough
• When working with the Trex RainEscape
trough material, ensure that the smooth/
shiny side always faces up. Do not seam
or overlap the troughs to extend its
length. Consult the installation guide
or call a Trex RainEscape specialist
at 1-877-348-1385 for options.
• Line up the 1-1/2 " score with the second joist.
• At the ledger slide 3 " of trough under
existing siding or flashing ensuring
trough sits on top of ledger board.
• Place first staple at ledger board on
inside joist to tack trough (Fig. 4).
• Unroll trough to downspout using 1-1/2 "
score mark on inside joist as guide.
• Cut length to back wall of downspout,
cutting a 1" wide by 3/4 " tab at center
edge of trough (fold tab down) to
prevent wicking (Fig. 5).
• To remove memory from sheet, backroll
the last few inches of the trough (Fig. 6).
• Pull trough tight ensuring memory is
released and place second staple on
inside joist through downspout (Fig. 7).
• On outside joist, form a trough into
downspout while lining up the edge of
trough with outside of joist. Place third
staple through trough and downspout
on outside joist (Fig. 8).
• Pull corner at ledger and outside joist
tight keeping entire length of trough
smooth and wrinkle-free; place fourth
staple on outside joist at ledger (Fig. 9).
• To test for correct slope, pour cup of
water on trough at ledger board
ensuring water runs to downspout.
• Continue stapling every 6 " to 8 " from
ledger to downspout on both joists
to secure.
STEP 3 : Remaining joists
• Follow step two for remaining joists
(Fig. 10).
STEP 4 : Tape all seams
• Make sure tape completely covers all
seams and anywhere a screw will
penetrate the Trex RainEscape system.
NOTE: When installing deck boards using a
pneumatic screw system, use extreme caution
to be plum to the joist. Carefully follow
instructions on how to operate the gun and
how to properly install deck fasteners.
1: Ensure the screw is centered on the joist.
2: If the trough or tape is torn during
install, repair immediately.
3: Make sure deck board is secure against
the previous to prevent movement
while fastening.
