• Make two parallel cuts down the center of the board to be replaced, then remove the
center piece.
• Using a small pry bar, remove the remaining pieces of decking from the tabs.
• Using a reciprocating saw, remove the tabs on the side of the board with the screw heads showing.
• Position new board into place, and carefully drive onto remaining tabs.
• Once the board is set into position, secure the loose edges with L-Bracket, Cortex, stainless steel, or
high-quality coated deck screws.

• When the deck is located in a corner
of the house, start with small
triangular piece of decking in the
corner and work your way out.
• Offset the center 1/2” towards the
long point of the joist, so screw will
not exit the side of the joist when
driven.

• Create a 2” long groove on the edge of
the plank at every joist. Do not groove
the full length of square shouldered
deck planks.
• Use TimberTech’s CONCEALoc Groove
Cutting Router Bit or a Freud model
#56-112 or Bosch model #85610M
1/4” slot cutting bit.
• Flip the plank over and start the
groove 3/8” off the bottom of the plank.
• Set the depth of the cut from 7/16” to
1/2”deep.
Note: Be sure to ID the side of the plank that has the directional
notch; the planks with IDs should be installed to the same side. See
Directional Notch on page 5.
