GENERAL INFORMATION Safety When working on any construction project, you should wear protective clothing and safety equipment. Wear safety glasses, gloves, a dust mask and long sleeves, particularly when cutting in confined spaces. Trex decking and railing are heavier and more flexible than wood. DO NOT try to lift the same quantity of Trex boards as you would traditional lumber. Go to www.trex.com for Safety Data Sheets (SDS).
GENERAL INFORMATION Trex Transcend®, Trex Enhance®, and Trex Select® Care and Cleaning Guide All exterior building materials require cleaning. Generally, soap and water is all that is required to clean Transcend, Enhance, and Select products.

GENERAL INFORMATION Trex Transcend®, Trex Enhance®, and Trex Select® Care and Cleaning Guide Problem Solution While this is not common, static electricity can occur on walking surfaces in dry climates or in areas where dry winds and dust-borne particles lay on the decking surfaces. Static electricity can build up on occupants walking across any composite decking surface, including Trex, then produce a small static shock if they touch a grounded metal surface such as railing, door, etc.
PLANNING AHEAD PLANNING AHEAD 6
PLANNING AHEAD Trex Decking: Railing (Including ADA Handrail): » When installing any Trex decking product, especially Trex Transcend Tropicals, it is a good idea to mix and match all of the boards on the job site prior to installation to ensure an appealing mix of light and dark tones. » DO NOT combine Trex Select decking with other Trex decking products. Trex Select boards are thinner than Transcend and Enhance boards.
PLANNING AHEAD/CONTINUED Installing Hot Tubs, Planters, and Seating: » Plan ahead proper joist spanning if required (this is especially important if installing a hot tub). » Refer to page 16 for Trex Decking Span Chart for specific loads. » Y ou need to consider the location of your pergola posts with respect to joists. However, you do not have to mount your plates between joists. It is possible to place blocks on the bottom of the joists and mount the Trex Pergola brackets through the blocks.

Decking and Fascia Recommended Fasteners If any condition occurs which is attributable to the use of non-recommended fasteners, such condition shall not be covered under the Trex Limited Warranty.
Trex® Fascia Installation Recommendations General Notes: » T rex Fascia utilized around the perimeter of a deck must be gapped with the same requirements as Trex decking to allow for expansion/contraction of the fascia » W hen using full size 1" x 12" fascia on 2" x 8" or larger rim joist 3 screws are required. Top screw should be placed 1" from the top of the rim joist, the second screw in the center of the rim joist, and the third screw 1" from the bottom of the rim joist.
Trex® Fascia Installation Recommendations WHEN USING DECK BOARDS AND COMPOSITE DECKING FASTENERS FOR FASCIA. While Trex prefers the previous methods of attachment for fascia applications, as these are the very best options, there are also other recommendations that can be followed for deck boards being used for fascia. Use two Trex recommended composite decking screws every 12". NOTE THAT FASCIA APPROVED FASTENERS CANNOT BE USED IN THIS APPLICATION.
NOTE: When using pneumatic or battery-operated equipment, adjust the pressure so that you only shoot the head of the screw to be flush with the board’s cap. DO NOT shoot the fastener head completely through the shell. Trex Products Near Low-E Windows Low-E glass reflects more sunlight. It has been observed that the extra reflectivity, combined with any concavity in the glass, can act like a concave mirror. This mirror effect concentrates sunlight onto outdoor objects, including that of decking and railing.
Rooftop and Sleeper Deck Systems – Pressure-Treated Framing A sleeper system is a substructure between a solid surface and Trex decking. Drainage, access, and airflow are critical. Water must be able to flow through and away from the deck. For repairs and removal of debris, joist system access may be necessary. NOTE: English measurements are shown. Convert to metric measurements if necessary. 3/16" (All Temps) 1/8" (>40°F) 3/16" (<40°F) 1/4" (>40°F) 1/2" (<40°F) 1/2" Max. Overhang Min.

Code Compliance Joist Spanning for Decking Trex decking meets all applicable national model building codes. The joists must be spaced on center according to the chart below. Be sure that joists are level and plumb. Trex decking must span at least three joists. For heavy items such as hot tubs, planters, etc., consult a local building engineer or inspector for span recommendations. If you want to minimize the appearance of joists through the spaces between boards, paint the top of your joists black.
Gapping and Overhang You must gap Trex decking both end-to-end and width-to-width. Gapping is necessary for drainage and the slight thermal expansion and contraction of Trex decking boards. Gapping also allows for shrinkage of the wood joist system. » ALWAYS follow Trex-recommended gapping guidelines. » Maximum allowable perpendicular overhang for all Trex decking is 1/2" (13 mm). » All decks require air circulation to keep them dry and looking good. To improve air flow, leave .
