2023 TREX SIGNATURE ® DECKING INSTALLATION GUIDE
S I G N A T U R E ® D E C K I N G CARE AND CLEANING GUIDE
S A F E T Y
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).
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.
All exterior building products require cleaning. Generally, only soap and water are required to clean Trex Signature® decking products. Some cleaning agents or chemicals such as solvents, acids or plasticizers can damage the surface of Trex Signature decking. Examples may include insect repellents, sunscreen products, or degreasing cleaning agents. Always refer to manufacturing labels as well as contact Trex customer care to determine if a specific product is safe to use. Many products will contain warning information regarding damage to plastic and these such products should never be used on Trex Signature decking. IF ANY CONDITION OCCURS WHICH IS ATTRIBUTABLE TO THE USE OF NON-RECOMMENDED CLEANING AGENT OR CHEMICALS, SUCH CONDITION SHALL NOT BE COVERED UNDER THE TREX LIMITED WARRANTY. PROBLEM SOLUTION
TOOLS
SPECIFIC DECK BOARD ATTACHMENT TOOLS
SAWS Miter Saw: When using a miter saw we recommend using the Trex Blade™ or a carbide-tipped blade with 60 teeth or more. The Trex Blade comes in three different sizes and is ideal for cutting all Trex decking and railing products. Jigsaw: For detailed and/or small cuts (i.e., cutting deck board to fit around a post), a jigsaw with a carbide-tipped blade can be used.
The affected area should be sprayed off with a hose to remove surface debris. Use warm soapy water and a soft bristle brush (do not use a wire brush) to remove dirt and debris from the embossing pattern.
Dirt and Debris
A pressure washer with no greater than 3100 psi** that has a fan attachment/adjustment and soap dispenser may be used to remove dirt or mud. Spray deck with soap, then follow by gently scrubbing each deck board with a soft bristle brush (do not use a wire brush). Spray/rinse each individual deck board using a fan tip no closer than 8-in (203 mm) from the decking surface. RINSE THOROUGHLY. If dirty water from cleaning is left to dry, a film will remain on the decking surface. When working with cement, concrete, mortar, or stucco, protect the decking as much as possible to prevent contact with dust particles on the decking surface. When dust particles from these products are exposed to heat or moisture, a reaction may occur causing them to become very difficult to remove. If particles get on the decking surface, Trex recommends using Sakrete™ Concrete Dissolver (www.sakrete.com/products/ concrete-dissolver). BE SURE TO FOLLOW MANUFACTURER’S INSTRUCTIONS. Hard water is water with high amounts of mineral deposits like lime, silica and calcium. When the water dries, deposits are left behind, leaving unsightly spots on surfaces. This is not a defect of Trex products but an issue with the water itself. Generally, these deposits can be cleaned with white vinegar on decking surfaces. Rinsing is required, so care should be taken to not use hard water for this purpose. If hard water must be used, dry with a cloth or use a blower to dry surfaces. In some cases a deck brightener* product may also be used to help clean hard water stains.
Using a Pressure Washer (General Cleaning Issues)
Screw Guns: Some Trex recommended deck fasteners are compatible with screw guns. Refer to the recommended fasteners page for more information.
Issues with Concrete, Cement, Mortar, or Stucco Dust
TigerClaw ® Pneumatic Gun: If choosing the TigerClaw TC-G Hidden Fasteners, the TigerClaw pneumatic gun is a terrific option that allows for quicker install time. Trex Router Bit: Trex decking routs to give extremely crisp edges when using the Trex Router Bit with standard router, and can be used with all Trex Hideaway Hidden Fasteners.
Hard Water Staining
DRILLS Install Trex recommended fasteners with standard power drills, impact drivers (use care if using impact drivers).
Most colored chalks are permanent and may discolor the surface. Use only Irwin Strait-Line® Dust-Off Marking Chalk (purple), DeWalt® Blue Chalk, or DeWalt® Orange High Visibility Chalk.
Chalk Lines
Remove all debris from the deck using a hose or broom. Once the deck surface is dry, apply a deck “brightener”* to the deck as directed by the manufacturer. Deck Brighteners contain oxalic acid, which will also remove tannins.
Tannins Due to Debris

A plastic shovel may be used to remove snow from the deck. Use calcium chloride or rock salt to melt the snow and ice from the deck surface.
Ice and Snow
*Tiger Claw ® is a registered trademark of Tiger Claw, Inc.
All food spills should be removed as soon as possible. The surface must be cleaned within seven days to maintain the stain warranty. To remove, spray off with a hose and use warm, soapy water and a soft bristle brush (do not use a wire brush) to remove spills from the embossing pattern.

S I G N A T U R E ® D E C K I N G CARE AND CLEANING GUIDE
PLANNING AHEAD TREX DECKING:
INSTALLING HOT TUBS, PLANTERS, AND SEATING: » P lan ahead proper joist spanning if required (this is especially important if installing a hot tub). » R efer to page 12 for Trex Decking Span Chart for specific loads.
» W hen installing ANY Trex decking product, 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. » F or added protection to wood framing, use Trex ® Protect ™ Joist and Beam Tape on the top of joists, rim joists, and ledger boards to help prevent rot and wood decay. Refer to trexprotect.com for more details. TREX DECKING TEMPERATURE: Like many other outdoor surfaces, such as concrete, asphalt, beach sand, wood decking, other brands of composite decking, etc., Trex decking can get hot due to weather and sun exposure. On such days, care needs to be taken to make sure skin does not have extended contact with the surface of the deck, especially with young children and those with special needs. Please note also that the darker the color, the hotter the deck will feel. For hotter climates, consumers should consider choosing a lighter color. TREX PRODUCTS NEAR LOW-E WINDOW: 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. This can result in an extreme amount of heat concentrated on areas of the decking surface. This can sometimes char the decking surface or cause the decking to slightly bow. TREX® OUTDOOR LIGHTING™: » P lan locations of lights, power supply, timer, and dimmer. These should be accessible for service if necessary. » Install wiring before decking and railing have been installed. » DO NOT run wires between joists and deck boards. Refer to www.trex.com to view detailed Trex lighting instructions. TREX® RAINESCAPE® DECK DRAINAGE SYSTEM: » P lan ahead for deck layout to allow for proper placement of Trex RainEscape within the joist system. » M ake sure joists are straight and square. See www.trex.com for more information on Trex RainEscape recommendations and installation. Trex RainEscape is manufactured and distributed by IBP, LLC, under a trademark license with Trex Company, Inc.
PROBLEM
SOLUTION
If debris such as pollen and dirt is allowed to remain on the deck surface, mold can feed on the biofilm. Using a hose and warm, soapy water with a soft bristle brush (do not use a wire brush) is recommended to remove the food source and mold.
Mold and Mildew
Call 1-800-BUY-TREX for detailed questions.
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. This condition can be decreased greatly with the use of a product call ACL Staticide®. Two products tested were General Purpose Staticide® and Heavy Duty Staticide®. Both are effective in greatly reducing static electricity on Trex decking surfaces. Apply full strength, using a mop on a dry decking surface, and allow to dry; no rinsing or diluting needed. Products are non-toxic, non-flammable, non-staining (will not change the color of decking surface), completely biodegradable, and safe to use. Product is water-based and may require a second application after rain or other weather conditions. Over a period of time, the effect of static will dissipate naturally on the decking surface. See link for more information on product: www.aclstaticide.com/antistatic_coatings.html
INSTALLING FIREPLACES AND/OR FIRE PITS WITH TREX DECKING: » D etermine if fire will be gas or wood burning. (Note: Most fire pits shown in Trex images are gas burning.) » F or gas, the fire pit is installed by cutting around the Trex decking. It is not to be installed on top of Trex decking. A fire-resistant material is installed under the fire pit and a protective wall made from stone or other fire-resistant material is installed to hold fire pit in place and also protect the decking from heat. » F or wood, fire pits are not recommended on top of Trex decking unless using a product called DeckProtect®*. Wood-burning fire pits can damage the decking due to extreme heat from the bottom of the fire pit and/or burning embers shooting onto the decking. DeckProtect® was tested on all Trex decking and there were no issues with burning of the decking surface when placed directly under a standard size portable fire pit along with the accompanying rack (Note: Rack is not available for all sizes, so check with manufacturer first for verification). Trex does recommend that the DeckProtect® padding/rack be moved from time to time for general cleaning underneath. It should be noted that even when using DeckProtect®, burning embers could shoot beyond the protective mat and burn the deck. For more information about this product, please visit their website at www.deckprotect.net or call 1-800-BUY-TREX. DeckProtect ® is a registered trademark of Infinite Heat Solutions.
Trex and Static Electricity
Use caution when using rubber-backed mats (i.e. welcome mats, etc.) as these may contain substances that can sometimes discolor or lighten the decking surface.
Rubber Mats
At this time, it is not recommended to curve Trex Signature decking.
Curving Trex Decking
Store decking on a flat level surface and ALWAYS use proper supports (dunnage). DO NOT store directly on the ground. When stacking decking bundles, supports (dunnage) should start approximately 8-in (203 mm) from each end and be spaced approximately 2-ft (0.61m) on center. In addition, supports (dunnage) should line up vertically/perpendicular to the decking product. Adjust support blocks (dunnage) accordingly if bundles are loose. For all Signature decking products the maximum stack height is 14 bundles (IMPORTANT TO NOTE THAT PROPER DUNNAGE SPACING MUST BE IN PLACE FOR THESE HEIGHTS). When stacking multiple bundles, ensure that dunnage lines up vertically down through each stack. ALWAYS cover decking products on site until ready to be installed.
Job Site Storage

T R E X ® 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. IN ADDITION ALWAYS refer to manufacturer instructions to ensure that recommended screws can be used for fascia applications. The top screw should be placed 1" from the top of the rim joist , and the second screw 1" from the bottom of the rim joist .
T R E X ® FASCIA INSTALLATION RECOMMENDATIONS
GENERAL NOTES: » Trex 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.
» When using 2" x 8" framing, attach fascia using 2 fascia approved fasteners; when using 2" x 10" or larger framing, attach fascia using 3 fascia approved fasteners. 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. WHEN USING APPROVED FASCIA FASTENERS: » Approved fascia fasteners can only be used with 1 x 8 or 1 x 12 fascia product and cannot be used with decking products that are being used as fascia trim or stair risers.
**IN ADDITION , also use a weather-resistant, construction-grade adhesive (adhesives that work with wood will work with Trex products) as a SECONDARY fastener when attaching deck boards used for fascia. Remember to wipe away any excess before it dries or is allowed to drip onto other Trex surfaces.

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.
FRAMING AND FASTENING TIPS
In most cases, install fasteners at a 90° angle (perpendicular to the board).
FASTENING TIP FOR TREX SIGNATURE® NOTE: When using pneumatic or battery-operated equip- ment, 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.
NOTE: English measurements are shown. Convert to metric measurements if necessary.
3/16" (All Temps)
CLEAN CUT BOARDS
At board ends on the deck's edge, you can install screws placed perpendicularly at the recommended distance, at minimum of 1" (25mm) from the board end and edge, without splitting the board. For butt joints, where boards meet over a single joist, add a 2" x 4" "nailer" board at the butt joint. This allows screw-in at 90 degrees and allows fasteners to be used at end of each board.
1/8" (>40°F) 3/16" (<40°F)
3/16" (5mm)
It is recommended that boards be clean cut on both ends a minimum of 3/16" (5mm). Ensure board ends are cut square. Composite decking is a great alternative to traditional wood decking. When building your deck and railing, it is recommended that code-approved structural material be used as the framing and joists. Check your local building codes for restrictions. Trex decking cannot be used for structural applications. Do not attach Trex decking directly to any solid surface or watertight system.
1/4" (>40°F) 1/2" (<40°F)
DOCK APPLICATIONS Trex decking contains no materials that will harm marine life and is safe for the environment. As long as dock is in intermittent contact with water, i.e., splashing and not in continuous direct contact with water, the durability of the Trex decking should not be affected. For docks, a 3/8" (10mm) width-to-width gap between boards is recommended to allow for increased drainage due to increased contact with water. In addition, stainless steel fasteners should be used. If there is sufficient contact between the dock and gasoline, grounding of the dock is also recommended.

recommends the use of Trex Universal Hidden Fasteners or 2" Starborn Cap-Tor ® xd - Epoxy Coated screws. NOTE: Trex recommended composite decking screws are too long when using 1-1/2" (38 mm) height as this will penetrate through the sleeper. For areas with the potential for debris buildup, a minimum 3-1/2" (89 mm) or greater height is recommended to allow the debris to be removed along with the use of either Trex Universal Hidden fasteners or any Trex recommended screws. » Always consult your local building code authority for proper details on roof and railing installation to the roof structure if required. » A ny deviation from these recommendations could result in voiding of the Trex warranty.
» It is recommended that building-code approved structural material be used as the supports. » T his system should not be allowed to float. It must be attached in a manner that secures the framing/system. » T he sleeper system must be level and have no uneven undulations. Any uneven areas of the substructure will transfer to the Trex decking, resulting in uneven decking. » T rex, when used with a sleeper system, must be supported below its entire length. If using in a roofing application, the supports must run the direction of the pitch of the roof to facilitate proper drainage. Sleeper should be placed perpendicular to the deck board orientation. » F or commercial applications, consult a local building code official for specific requirements. » If installing decking at an angle, decrease spans 4" (100 mm) for each of the above. (12" (305 mm) for residential and 8" (204 mm) for commercial.) » F or sleeper systems where small debris (pine needles, leaves, sand, dirt) can accumulate either between or under deck boards, a minimum of 1-1/2" (38mm) height is allowable.

CODE COMPLIANCE
GAPPING AND O V E R H A N G
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
ADJUST JOIST SPANNING TO ACCOMMODATE ANGLED DECKING PATTERNS
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. » M aximum allowable perpendicular overhang for all Trex decking is 3/4 " (19 mm). » A ll decks require air circulation to keep them dry and looking good. To improve air flow, leave .openings under the decking or increase gapping to 3/8 " (10 mm).

(hereinafter “Trex”) warrants to the original end-use purchaser (“Purchaser”) that, for the applicable Warranty Period set forth in Table I below, when properly installed, used and maintained under normal use and service conditions and in accordance with Trex’s written instructions, Trex® product set forth in Table I below (the “Product”) shall perform as follows: Physical Integrity: The Product shall be free from material defects in workmanship and materials, and shall not split, splinter, rot or suffer structural damage from termites or fungal decay. Fade Resistance: The Product shall not fade in color from light and weathering exposure as measured by color change of (a) more than 5 Delta E (CIE) units for twenty-five years from the date of original purchase, and (b) more than 15 Delta E (CIE) units for the remainder of the Warranty Period, if any. While the Product is designed to resist fading, no material is fade proof when exposed to years of UV exposure and the elements. The Product is designed to resist fading under normal weather conditions and will not fade by more than the number of Delta E (CIE) units indicated above. Stain Resistance: The Product shall be resistant to permanent staining resulting from spills of food and beverage items including ketchup, mustard, salad oils, tea, wine, coffee, fruit punch, barbeque sauce, sodas and other food and beverage related items that would typically be present on a residential deck, or mold and mildew naturally occurring in the environment, provided that such substances are removed from the Product with soap and water within one (1) week of exposure of the food or beverage to the surface or first appearance of the mold and mildew.
