Always be sure to check and cut the factory cut
ends of all boards to ensure they are square.
• In areas with obstructed airflow such as roofs and
on-grade applications, a minimum of 1-1/2”, sleeper
system,is required.
• Sleeper system must be supported by and connected to
the substructure over which the deck is built.
• To further minimize expansion and contraction, proper
ventilation and airflow should be considered.
• On-grade decks must have additional provisions for
drainage beneath the deck structure.
• For best practices, decking should not be installed in
applications where ventilation and airflow cannot be
achieved.
• Do not use CONCEALoc Hidden Fasteners or L-Bracket
for stair installation.
• For gapping requirements, see page 3
• 100-square-foot coverage box. Includes stainless steel
clips and screws.
• Bulk Bucket – 1,000-square-foot coverage. Includes
stainless steel clips and screws.
• CONCEALoc Gun Pail – 500-square-foot coverage for
use with the TigerClaw pneumatic installation tool
sold by FastenMaster. Includes quality coated
pneumatic fasteners. Stainless steel fasteners for
coastal applications available through FastenMaster.
Pneumatic tool must be tuned specifically to install
lightweight AZEK Deck. Failure to do so can result
in less than desired securing/tightness of fastener,
boards lifting from joists, boards feeling loose or
movement and could generate squeaking/noise.
• L-Bracket – avoid face-screwing by using the L-Bracket
on first and last boards or as a butt seam clip to ensure
a fastener-free surface.
• CONCEALoc Router Bit – cut a 2” wide groove on a solid
board for a perfect CONCEALoc fastener fit – even allows
for cutting an installed board over a joist.
• CONCEALoc screw packs available on TimberTech.com
• If using the CONCEALoc Gun Pail with the TigerClaw
Installation Gun please refer to the retail packaging for
further installation guidelines.

• Pre-drill with 5/32” drill bit and fasten outer
edge of the first board at each framing support
3/4” from the edge using TOPLoc for PRO &
EDGE. For a complete fastener-free surface,
the L-Bracket or Cortex can be used on first and
last boards. (Except PRO Terrain, EDGE Prime,
EDGE Prime+ and Reliaboard.)
• For further instructions for the L-Bracket or
Cortex, please refer to the instructions in the
package.
