Installation Guide

Fasteners Continued
Always use screws designated for use with composite
decking material. Always test the screws on a scrap
piece of board to ensure the screws do not cause the
surface of the decking to mushroom or bulge around
the head of the screw. If it does cause this issue,
change to a different brand of screw.
When choosing which screws/nails to use always
check first with your local home centers and hardware
stores to see if they have screws that are engineered
specifically for composite wood. These screws/nails
will always work and give NewTechWood’s products
the best looking outcome, using other screws/nails
that are not recommended for composite could
potentially damage/harm the decking. If you are
unsure which screw/nail to use contact your
manufacturer for more information.
Recommend screws from other manufacturers:
1. Cap-tor xd screws by Starborn Industries
Acclimate
Acclimating at least 2 days prior to installation is
recommended
Acclimating the boards will get rid of any unwanted
shrinkage issues seen during and after installation.
Note: Always remember when allowing the boards
to acclimate at the job site it is important to put it
on a flat and even surface. If put on an uneven
surface there is a possibility that the boards could
warp to the shape of the terrain.

Sealant
NewTechWood recommends the following sealants to
be used on cut ends:
1. Armorseal Rexthane by Sherwin-Williams
2. Corothane I-Aliphatic by Sherwin-Williams
Routing
Solid boards can be routed for hidden fasteners to be
placed in them as shown below.
Note: Boards should never be routed the entire
length.
Fascia boards can also be routed to allow for
expansion and contraction.
