ith wide plank over 4in extra care is
necessary for good performance since the
units move more with changing conditions.
Proper acclimation before and after installation is critical. After acclimation and
before installation, sealing the back surface
may help prevent some cupping normally
associated with wider widths.
This flooring is normally made in 3in to 8in widths and
may have countersunk holes for securing planks with
wood screws. These holes are then filled with wood plugs.
Random width Plank is installed in the same manner
as strip flooring, alternating courses by widths. Start
with widest boards, then the next width, etc., and repeat
the pattern. Manufacturers' instructions for fastening
the flooring vary and should be followed.
The general practice is to blind nail through the tongue
as with conventional strip flooring. Then countersink one
or more flat head screws, No. 7 - No. 9 phillips head or
dry wall screws at each end of each plank and at intervals
along the plank to hold it securely. Cover the screws
with wood plugs glued into the holes. Take care not to use
too many screws which, with the plugs in place, will tend
to give the flooring a "polka-dot" appearance.
Be sure the screws are the right length. Use 1in if the
flooring is laid over 3/4in plywood on a slab. Use 1in to 1-1/4in
in wood joist construction or over screeds. Some manufacturers
recommend face nailing in addition to other
fastenings.
Another practice sometimes recommended is to leave
a slight expansion crack, about the thickness of a putty
knife, between planks. Consult manufacturer's installation
instructions for details.
