PRE-INSTALLATION & JOBSITE CONDITIONS

Your solid hardwood flooring must undergo an acclimatization period

(i.e. it must be stored in the room where it will be laid) for at least 72

hours prior to installation or test the floor with appropriate moisture

meter. The moisture levels should differ no more than 4% between the

subfloor and the planks. For wood flooring plank products (products

wider than 3”) there should be no more than 2% moisture difference

between the flooring and subfloor.

SUBFLOOR REQUIREMENTS

The following subfloor recommendations are intended to

complement the installation of hardwood flooring as an interior

finish. Hardwood flooring is not a structural component. These

recommendations are not intended to supersede federal, state or

local building codes, but as with many other interior finish

products, may require modifying existing structural components

for a successful installation.

We recommend 3 types of sub-floors- plywood/OSB, solid wood planks

(1 X 6 or larger), or sleepers (2 X 4 inch). Each sub-floor has separate

installation instructions as follows:

SOLID WOOD SUBFLOOR- Solid planks should be nailed diagonally

across the joists with a ¼” gap between the boards.

CONCRETE- There are several methods of installing solid flooring

over concrete. One method is to use 5/8” or ¾” plywood. It is

recommended that a vapor barrier be used prior to installation of the

floor, preferably, a 4-6 mil. Polyethylene film with enough excess to be

placed under the baseboards. Fasten the plywood to the concrete

using the appropriate fasteners. Another way of laying the plywood on

concrete is to cut the plywood in 4’ X 4’ squares and lay it in mastic. A

moisture barrier must also be used with this method.

Another alternative would be to use “sleepers”. This method uses

treated 2” X 4” lumber laid flat in asphalt mastic every 12 inches at

right angles to the finished floor. Overlap or stagger the sleepers by at

least 4’ and make sure each one is securely imbedded into the mastic.

A polyethylene moisture barrier is then laid over the sleepers. Be

certain not to puncture or bunch up the poly, or it will not create an

effective vapor barrier. Nail the flooring through the plastic into the

sleepers.

BEFORE YOU START:

• Plan your layout and determine the direction of the

installation in the room. Planks installed parallel to windows

accent the hardwood best.

• Remove existing base, shoe molding or threshold carefully.

They can be used to cover the ¾” expansion gap left around

the perimeter of the room.

• Undercut doors and casings using a handsaw laid flat on a

piece of scrap flooring. This will eliminate difficult scribe cuts.

• Sub-floors should be clean prior to the floor installation.

Sweep the area to remove all dust and debris.

• Make sure the subfloor is dry to 12% moisture content or

less.

• Blending of cartons: To achieve a uniform installation

appearance, preselect and set aside hardwood planks that

blend best with all trims and moldings. Install these planks

next to best blended moldings.

• Floor should be installed blending planks from several

cartons at the same time to ensure good color and shade

mixture throughout the installation.

• Be attentive to staggering the ends of the boards at least 4” -

6” (10-15 cm) when possible in adjacent rows.

• Do not install in areas of high moisture such as bathrooms

and powder rooms.

Solid Hardwood flooring may be installed on or above grade

provided that the sub-floor is:

• Flat - within ¼” in a 10’ radius.

• Dry - always test the sub-floor with the appropriate

moisture meter. Installation cannot continue until the

sub-floor moisture does not exceed 12% and the sub-

floor and flooring moisture differ no more than 4%. On

3”or wider the sub-floor and the flooring being

installed should not differ more than 2%.

• Clean – all construction debris, soil, mud and any

other objects on or adhering to the floor are scraped

and swept away before the installation.

• Sound – All damaged or swollen sub-flooring should

be replaced. Check the floor for squeaks / loose

components, repair any found by adding fasteners or

adhesive.

• Do not Install Solid Hardwood Flooring over radiant

heating systems or attempt to glue the flooring directly

to any sub-floor surface.

Do not install Solid Hardwood Flooring over particleboard,

fiberboard, wafer board, or pressed wood panel
