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 rst with your local home centers and hardware
stores to see if they have screws that are engineered specically 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: 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 at and even surface. If put on an uneven surface there is a possibility that the boards
could warp to the shape of the terrain.
Routing
Solid boards can be routed for hidden fasteners to be placed in them as shown in Diagram 4.
Note: Boards should never be routed the entire length.
Fascia boards can also be routed to
allow for expansion and contraction.
