Fascia and Riser Boards
Using screws with proper installation of TimberTech
Fascia provides the best long-term holding. TimberTech
recommends the use of TimberTech TOPLoc Fascia Fasteners
for best results. Refer to gapping requirements on page 3 for
proper installation.
For Use with TOPloc Fascia Fasteners:
Using the TOPLoc Fascia Bit, pre-drill 2” from the top and
bottom alternating a maximum of 12”. It is recommended
that screws are evenly spaced for the best look.
• Set fascia in place being sure to follow proper gapping
requirements.
• Drive TOPLoc fascia fastener 90 degrees with the fascia
surface so that the screw head is flush with the surface.
Do not completely torque down screw; screw should
serve as a hanging mechanism to allow for expansion and
contraction in the fascia.
• Continue fastening in pattern described being sure to work
left to right or right to left. This will ensure flatness in the fascia.
• If preferred, TopLoc Fascia Fasteners may be installed 2
every 12", 2" from the top and bottom.

Decking
Installation Preparation
Follow these guidelines for best deck installation:
• TimberTech Deck Boards are one-sided products. Deck Boards are to
be installed with the grain side up for the walking surface. Fascia is
to be installed grain side out.
• TimberTech Fascia is one-sided.
• Prior to installation, check to make sure all joists are level,
structurally sound, and there are no nails or screws protruding.
• Ensure that all joists are crowned correctly and that all joists are
level across the top as TimberTech Deck will conform to the surface
contour of the substructure.
• Proper joist spacing is required for proper installation. Joist spacing
should never exceed 16” on center. For a more rigid feel,
12” may be preferred.
16”BASIC INSTALLATION
SUBSTRUCTURE
16” on center maximum joists.
(12” on center for commercial applications)
PICTURE FRAME INSTALLATION
SUBSTRUCTURE
16” on center maximum joists plus additional
support for picture frame structure (12” on
center for commercial applications)
DIAGONAL INSTALLATION
SUBSTRUCTURE
12” on center maximum joists.
More severe angles may require closer joist
spacing.

• For best results, installing solid wood blocking between each joist,
placed every 4’ - 6’ within the structure, can help reduce movement
or twisting of the joists. Limiting joist movement can help reduce
excessive gapping and also ensure more uniform finished surface of
the TimberTech Deck.
