Installation Guide

On the other side of the board, place a hidden
fastener into the slot and center on the joist
(figure 3). Install a #7, 1-5/8" stainless steel
screw at a 90° angle through the fastener and
drive flush. Do not over-tighten. The fastener
wings must remain level with the joist for the
next board to fit correctly (figure 4). Install one
fastener at each joist location. Slide the next
board into place so the wings on the previous
fasteners fit into the slot on the side of the
board. Make sure the side gap between the
boards is 1/4".
To keep the interior boards from moving over
time, we recommend pinning the boards at the
center of their length using a #7, 1-5/8" stain-
less steel screw. This holds the deck board in
place at the center
of each board and
allows the decking
to expand/contract
at the ends of the
boards. Pre-drill in
the slot of the deck
board with an 1/8"
drill bit (inset of fig-
ure 5). Drive screw
into the slot so it’s
flush with the bottom
of the groove (figure
5). This will allow
you to properly fit a
hidden fastener into the slot. Install hid-
den fastener clip over the screw and
centered over the joist. Fasten using a #7,
1-5/8" stainless steel screw at a 90° angle
through the hidden fastener and drive flush
with the clip (figure 6). The fastener wings
must remain level with the joist for the next
board to fit correctly (figure 4).
Install one fastener at each joist location along
the length of the board. For installations where
deck boards are butted end-to-end at the joist,
we recommend adding an 8" block and using
a hidden fastener clip at the end of each
board (figures 7 and 8). Be sure to gap the
boards as previously described. Repeat the
process for each board until the outside edge
of the final board is fastened with screws.
Use fascia to conceal the board profile and
inhibit board movement over time. If no fascia
is being used, the entire perimeter of the deck
should be fastened to the rim joist with screws.
Use two fasteners at the end of each board.
These screws will be inconspicuous once the
railing is installed.
Apply these same principles when installing
stair treads.

Color variation: Most composites will have color variations from piece to piece. This is due to naturally occurring variations in wood fibers and polymers. Purchasing all required decking material at one time
is recommended, as manufacturing runs can produce slightly different colors. Do not install if color variation is not acceptable. Composite Decking will lighten over time, and color variation is not covered by the
warranty. This color-tone shift is dependent upon exposure to sunlight and other environmental factors, and is generally completed in 60 to 90 days. Gray products may turn a light brown before changing to
lighter gray. Preventing mold and mildew growth on composite decking: Mold and mildew can be a nuisance on any exterior building surface, regardless of the material. If the conditions are right, they
will spawn on wood, plastic, concrete, metal and other surfaces. Mold formation is most prevalent in consistently wet, shaded areas. Spores from the natural environment are carried by the wind and commonly land
on decks surfaces. It is important to note that the appearance of mold/mildew is a function of nature, not necessarily a deficiency with any of the material on which it grows. Cleaning: Periodic washing with soap/
detergent and water will help remove surface dirt. This will also help prevent the buildup of pollen, debris and spores that can cause and accelerate mold/mildew growth. CAUTION: A pressure washer should not
be used to “blast” mold/mildew or soils from a deck surface. The abrasive nature of the water stream can potentially damage the material by driving the spores into the material, which may create a more challenging
problem to remediate. A pressure washer with a fan-tipped nozzle should be used only to lightly wet or rinse wood or composite deck surfaces. There are many deck wash and exterior cleaning products available at
retail. It is important to make sure you use a cleaner specifically intended for your application. After selecting a product, be certain to read, understand and follow all instructions supplied by the manufacturer. Some
cleaning products and inhibitors may be more effective than others, depending on the environmental conditions your deck is subjected to. Additionally, it is always a good idea to test the cleaner in a small, inconspicuous
area prior to applying it to the entire deck. Mold inhibitors: As with deck washes, there are several mold-inhibitor products available from paint stores, hardware stores, online outlets and home centers to help
prevent long-term mold/mildew growth. For any product selected, be certain to read, understand and follow all instructions provided by the manufacturer. Depending upon the environmental factors affecting your
deck, some preventive cleaning products may be more effective than others. It may be necessary to try more than one product. For ongoing preventive maintenance, follow the manufacturer’s recommendation.
Composite Decking is not suitable for structural use. It should not be used for primary load-bearing members such as posts, joists, beams or stringers. The same common-sense precautions should be taken when
handling Composite Decking as with wood or other building materials. Dust masks and eye protection devices are recommended to avoid possible irritation from sawdust and chips. Gloves will help to protect
the hands. Hands should be washed after doing construction work. The diagrams and instructions in this brochure are for illustration purposes only and are not meant to replace a licensed professional. Any
