TREX Porch Flooring Installation

TREX® Porch Flooring Installation Guidelines

NOTE: When installing Trex Porch Floorboards in a non-covered environment, the porch structure should be sloped to help allow for proper drainage. Joists should be sloped 1/8" per foot away from the house to facilitate drainage. Refer to your local building code official for recommendations BEFORE building sub-structure. When installing Trex Porch Floorboards under a covered roof, no slope is required.

NOTE: Maximum spacing of porch floorboards using Hideaway system is 16" on center.

Installing Start Clips and First Porch Floorboard
TREX PORCH
1.  Measure 3/8" off edge of ledger board and install start clip onto ledger board, centered on each joist. Secure clips with screws.
2.  Push grooved edge (longer edge side) of porch floorboard into start clips. Important: First board MUST be straight and well secured.

Installing Universal Fasteners
3.  Insert fastener into grooved edge (shorter edge side) of porch floorboard, making sure to align screw hole in fastener with center of each joist.

4.  IT IS SUGGESTED THAT IN ORDER TO KEEP THE FASTENER STRAIGHT AND SECURE, CUT AN 18" PIECE OF PORCH FLOORBOARD SCRAP BOARD AND USE THIS AS AN AID (USE SMALLER LIP SIDE) TO HELP HOLD THE HIDDEN FASTENER DOWN BEFORE SCREWING THIS IN. This will help make sure the fastener stays straight for remaining boards to be attached.

5.  Fully tighten (but DO NOT over tighten) the screw into each joist while keeping the scrap board in place against the hidden fastener.

Installing Second Porch Floorboard

6.   Slide second porch floorboard into place, making sure fasteners fit into groove. Install the next universal fastener on the other side of the second porch floorboard in the same manner as Steps 3 through 5.

Installing Last Porch Floorboard
Option 1:
Using Fascia Board
7a.   Pre-drill pilot holes at an angle through grooved edge of porch floorboard into ledger board. Install 2½" screws through pilot holes to secure. Attach fascia board flush with porch floorboard surface.

NOTE: In most cases, there will be additional screws that come with the Trex Universal Hidden Fasteners. These screws can also be used for attachment of the last board in the method shown above.

Option 2:
With Porch Floorboard Overhang

NOTE: This side of porch floorboard will have to be cut flush to not show grooves. Note that color of porch floorboard will be slightly different at cut edge.

7b.   Pre-drill pilot holes at 45° angle from below deck surface through rim joist. Seat last porch floorboard into fasteners overhanging rim joist. Secure porch floorboard with 2½" screws using pilot holes. Position fascia board below overhanging porch floorboard.
