Because some minor collateral damage may
occur during the installation of a prefinished floor,
minor touch-ups with the use of the appropriate
colored putty, marker-stick or filler is considered
acceptable industry practice, provided the these
repairs pass inspection from a standing position.

Using glue-assist and butt-joint glue procedures set the second row in place. Use offcuts if lengths
are suitable and stagger end joints as required (see above). Blind- nail along the tongue as before or, if
working space permits, use the nail gun.
Continue with subsequent rows sing glue-assist and butt-joint glue procedures. To avoid a repetitive or
predictable board patterns, cut some boards to random lengths to begin rows. Open new packages
several at a time and rack and inspect boards as described above. Ensure 1/2” expansion space is
maintained at all perimeter walls and other vertical obstacles. Maintain nailing schedule and keep butt
joints staggered as described above.
In the last couple of rows, there may not be space to use the nail gun, so revert to using the finish nailer
with glue-assist and butt-joint glue procedures as before, blind nailing through the tongue. For the final
row, measure the gap to the wall, allowing expansion space, and rip a row of boards to the required
width. Top nail the final row into place using brads or finishing nails placed 1/4” in from the edge. Install
moldings and transitions as required.

It is a common practice among some installers to
use a ‘full spread glue down’ on the first and last
few rows of a nail down installation in order to
avoid top nailing. This practice is not recommended
by Kentwood for any nail down installation. Any use
of full spread glue down on first and/or last rows
within a nail down installation will automatically void
the product warranty.
a guide. If starting the installation against a wall, place boards with the groove side facing the wall and
remember to allow expansion space.
Top nail along the groove edge with the brad nailer using minimum 18g 1½” fasteners set 10 to
12” apart, with a fastener 1 to 3” from each end of each board. Keep the nailer perpendicular to the
direction of the flooring and set nails no less 1/4” in from the edge of the board.
Using a pneumatic finish nailer, blind nail along the tongue edge at a 45° angle. Follow the nailing schedule
specified above, spacing the recommended fasteners as indicated. Ensure a fastener is placed as
indicated near the end of each board.
At the end of the row, cut a board to fit, allowing 1/2” expansion space.
