USE TWO FASTENERS ON
EACH SIDE OF JOINT
• For premium results use Cortex
®
Collated Fastening System. Use a standard 18V cordless impact
drill. Set the Cortex® fastener perpendicular to the trimboard using the Cortex setting tool. Place
the PVC trim plug into the hole with the trim surface side up and gently tap until it is flush with the
trimboard. See packaging directions for detailed installation tips.
• For best results, use fasteners designed for wood trim and wood siding. These fasteners have a
thinner shank, blunt point, and full round head.
• A #8 trim screw may be used and works well with AZEK Trim and Moulding products.
• To take advantage of the performance of AZEK Trim and Moulding products, use a highly durable
fastener such as stainless steel or hot dipped galvanized.
• Staples, small brads, and wire nails must not be used.
• The fasteners should be long enough to penetrate the solid wood substrate a minimum of 1 ½".
• Standard nail guns work well with AZEK Trim and Moulding products. If using pneumatic tools,
the air pressure should be regulated so fasteners slightly penetrate the surface.
• Like wood, use 2 fasteners per every framing member for trimboard applications. Trimboards
12” or wider, as well as sheets, will require additional fasteners, not to exceed 8” on center. See
illustration below.
• Fasteners must be installed within 2” of the end of each board. See illustration below.
• There must be 2 fasteners on each side of a board joint (scarf, miter, etc.).
• All fasteners must hit a solid framing member.
• AZEK Trim and Moulding products should be fastened into a flat, solid substrate. Fastening AZEK
material into hollow or uneven areas must be avoided.
• Pre-drilling is typically not required unless a large fastener is used or product is installed in low
temperatures.
• 3/8” and 1/2” AZEK Sheet product is not intended to be ripped into trim pieces. These profiles
must be glued to a substrate and mechanically fastened.
• AZEK BEADBOARD AND COLUMN WRAP FASTENING
CONSIDERATIONS
(Use one of the following):
• #7 trim screw
• 16 gauge T-nail
• 15 gauge round head (for 1/2” Beadboard only)
• Fasteners should be a minimum of 1 ½” in length
FASTENING
STORAGE & HANDLING
• Store AZEK Trim and Moulding products on a flat and level surface.
• Since AZEK Trim and Moulding products are more flexible than wood, they may conform to uneven
surfaces. Ensure that storage areas, as well as all framing and substructures, are flat and level to
minimize uneven surfaces.
• AZEK Trim and Moulding products have a density comparable to pine and should be handled in a
fashion as pine would be handled to avoid damage.
• Units of AZEK Trim and Moulding products are shipped from the manufacturer in a protective
covering. If covering has been removed, take care to keep product free of dirt and debris at jobsite.
If product gets dirty, clean after installation.
• Care should be taken in handling the individually wrapped column wraps to prevent tearing of tape
or cracking at miter lock corner joints.
• For trim with protective film, trim should be kept dry prior to installation. Do not expose film
to direct sunlight for extended periods. Protective film can be removed prior to, during or
immediately after installation.
CUTTING
• AZEK Trim and Moulding products can be cut using the same tools used to cut
lumber.
• Carbide tipped blades designed to cut wood work well. Avoid using fine tooth
metal cutting blades.
• Rough edges from cutting may be caused by excessive friction, poor board
support, or worn or improper tooling.
DRILLING
• AZEK Trim and Moulding products can be drilled using the same tools used to drill
lumber.
• Drilling AZEK Trim and Moulding products is similar to drilling a hardwood. Care
should be taken to avoid frictional heat build-up.
• Periodic removal of AZEK shavings from the drill hole may be necessary.
• AZEK Trim and Moulding products can be routed using standard router bits and
the same tools used to rout lumber.
• Carbide tipped router bits are recommended.
• Routing AZEK Trim and Moulding products provides a crisp, clean edge.
