Instructions / Assembly

On the other side of the board, place a
DeckoRail 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
DeckoRail 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 DeckoRail 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" stainless
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 figure 5).
Drive screw into the
slot so it’s flush with
the bottom of the
groove (figure 5). This
will allow you to prop-
erly fit a DeckoRail
hidden fasten-
er into the slot.
Install DeckoRail
hidden 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 DeckoRail 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 DeckoRail fastener at each joist loca-
tion along the length of the board. For installa-
tions where deck boards are butted end-to-end
at the joist, we recommend adding an 8" block
and using a DeckoRail 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.

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.
DeckoRail deck boards are 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 DeckoRail 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
