Surface fastening and fascia instructions
All brands of Fiberon decking may be surface fastened. Annular
thread, ring shank and spiral shank nails, of sufcient length, have
excellent holding power and produce good results, but screws
have superior holding power. Use only screws designed for
composite decking. Plain, galvanized surface fasteners are not
recommended. Do not use traditional bugle-head screws.
For best results, use either stainless steel composite deck screws,
color match stainless steel decking screws or the Cortex hidden
fastener system. These screws are engineered specically to work
with composite decking and prevent mushrooming, resulting in
better looking nished projects. Screw heads must be ush with
board surface or countersunk for color matching Cortex plugs. Pre-
drilling is recommended for all surface fasteners and is necessary for
end of board screw holes and cold climates to prevent immediate or
eventual end splitting. Pre-drilling all holes will result in better looking
nished projects. Use caution to avoid overtightening fasteners or it
will induce cracking at board ends and can lead to eventual cracking
around other fasteners. Do not surface fasten within 1

in. (4 cm) of
the end of a board or 1 in. (3 cm) from the side of the board.
Tip: Straight rows of fasteners look cleaner and less noticable than
uneven rows. White chalk, straight boards or string lines can be
used as guides for straight lines.

Fascia is intended as a non-structural covering for rim joists, risers
and stringers. Install screws at a maximum 12 in. (30 cm) interval,
with three screws across the face at each interval. For Paramount,
also apply a zigzag bead of high quality exterior adhesive to the
entire length of the back (smooth side) of the board, within 2 in. (5
cm) of the edges and ends. Do not overtighten screws as buckling
and cracking may result. Install with 1/8 in. (3 mm) spacing between
the edges and ends in temperatures above 50˚ F (10˚ C). Leave 3/16
in. (5 mm) space between edges and ends in temperatures below
50˚ F (10˚ C).
Always drive surface fasteners in at a 90˚ angle to the decking
surface with two fasteners at every joist location. Do not toe-nail
screws into the joist. Instead, place blocking/sister joists to allow
perpendicular installation of surface fasteners at board ends.
Fasteners recommended for use with Fiberon grooved (GV) deck
boards include Phantom Hidden Fasteners and Phantom End Clip
Hidden Fasteners.

recommendations, including specic instructions for square edge
and grooved Paramount deck boards.
