Installation Instructions

Solid strip and plank wood floors can be installed successfully above grade level
or on grade, but are not recommended for installation below grade.
• The entire flooring level is considered to be below grade where soil is present
along any perimeter wall and is more than 3” above the installed wood flooring
level. Ground should be sloped away from the house for proper drainage. (Follow
local building codes.)
SUBFLOORS – WOOD JOIST SYSTEMS
In the Chapter 4 of The National Wood Flooring Association's Installation Guidelines
(Wood Subfloor Guidelines), it states that wood subfloors must be flat, clean, dry,
structurally sound, free of squeaks, and free of protruding fasteners. For installations
using mechanical fasteners of 1 1/2” and longer, the subfloor should be flat to within 1/4”
in 10', or 3/16” in 6'.
If peaks or valleys in the subfloor exceed the tolerances specified above, sand down the
high spots and fill the low spots with a leveling compound or other material approved for
use under wood flooring. However, it is the builder's or general contractor's responsibility
to provide the wood flooring contractor with a subfloor that is within the tolerances listed
above.
If there is movement or squeaks in the subfloor, refasten the subfloor to the joists in
problem areas. Protruding fasteners are easily remedied by driving those fasteners
deeper into the subfloor
SUBFLOORS – CONCRETE SLAB
When installing solid strip and solid plank flooring over concrete, a vapor retarder
is always required over the concrete slab and below the subflooring material. A
minimum 6 mil construction grade polyethylene film, with perm of 0.13, or other
impermeable material with a perm of 0.15 or less is recommended.
Wego does not recommend our solid hardwood floors to be installed by the
direct-glue down method over a concrete slab.
