  • Preservative Wood is not recommended for furring
  • The spacers may never be longer than 10’.
  • There must be a 1/2” gap between the spacers.
  • There should be 21 screws in a 4’x 8’ board.
  • There should be 24 screws in a 4’x 10’ board.
  • All holes must be pre-drilled over-sized using a 5/16” carbide tip drill bit.
  • Remember to install the center screw first then continue in a spiral.
  • The screws should only be snug against the panel & not screwed in as tight as possible.
  • Over-tightening the screws will restrict movement & destroy the board.
