Recommended Installation by Line:
Engineered
Collection: 5” plank allowed for GLUE, NAIL or FLOAT. Can be installed above, on
or below grade.
Engineered Collection: 3 ¼”,
3 5/8” or 4” plank allowed for GLUE or NAIL. Can be installed
above, on or below grade.
Solid Collection:
NAIL ONLY. Can be installed above or on grade.
I. Sub-floors
Sub-floor must be flat, meeting a minimum
of 3/16” within 10’ or 1/8” in 6’.
Concrete sub-floors – Grind high spots or use a cement based leveling material
(minimum
Compressive strength 3000 psi) to fill all low spots. Follow the
leveling compound manufacturer’s instruction. Leveling compounds
must be allowed to thoroughly cure and dry prior to installation of
wood flooring.
Wood sub-floors – For staple down application use layers of 15 lb. felt wooden shims to
fill
low spots. Staples must be able to penetrate for holding power.
Recommended
Sub-floor Surfaces
Concrete sub-floors – concrete
slabs should be of high compressive strength and constructed
to prevent groundwater from permeating the concrete. Engineered
hardwood flooring can be installed on, above, or below-grade. In
addition, it can be installed over above-ground, suspended concrete
floors. The suspended concrete must be a minimum of 1 ½” thick and
must be structurally sound. The exception to this is lightweight
concrete (which usually contains high amounts of gypsum) having a
density of 100 pounds or less per cubic foot. Test for lightweight
concrete by using a nail to scratch the surface of the concrete. If the
concrete crumbles or turns to powder, it is not sound and you should
NOT
install the hardwood flooring.
Wood Sub-Floors – Preferred Sub-flooring ¾” (23/32”,
18.3mm) CDX grade plywood
sub-floor / underlayment (Exposure 1), 4’x8’ sheets or OSB sub-floor /
underlayment grade, PS2 rated, sealed side down, with joist spacing of
19.2” (475) on center or less.
Minimum Sub-flooring 5/8” (19/32”, 15.1mm) CDX grade plywood
sub-floor / underlayment (Exposure 1), 4’x8’ sheets, maximum 16” on
center joist construction. Follow panel manufacturer’s recommendations
for spacing and fastening. Typical panel spacing and fastening for joist
systems, 1/8” (3.2mm) around perimeter and fastened every 6” (150mm)
on bearing edges and every 12”(300mm) along intermediate supports.
Installation of flooring should not be made over joists spacing greater
then 19.2 on center or parallel to the joists unless the sub-floor has been
properly strengthened, applying a second layer of underlayment may be
necessary to bring the overall sub-floor thickness to 1 1/8”.
- Test the moisture content of the wood sub-floor and wood flooring with
a pin type moisture meter. Wood sub-floor must not exceed 13% and
the wood flooring should be within 4% of the wood sub-floor.
-For existing wood floors, install the new flooring at right angles to the
existing flooring.
-Do not glue, staple or nail down hardwood flooring over particle board.
-Do not install over existing glue down hardwood floors.
