Sub-Floor Type: Cork (Acoustic)
Glue-Down Application — Make sure cork is level and permanently bonded to the sub-floor with full spread moisture cured
urethane adhesive. The minimum density required for cork is 11.4 lbs/cubic foot; maximum density should not exceed
13 lbs./cubic foot. The cork should be no more than 1/4" thick and constructed of pure cork with polyurethane binders,
installed to the manufacturer’s specifications. Cork must be rolled into adhesive. Cork is not a moisture barrier. Before
application of cork, concrete must be sealed (StrateStuff Substrate Safeguard recommended).
Sub-Floor Type: Ceramic, Terrazzo, Slate, or Marble
Glue-Down Application — The above tile products should be level and permanently bonded to the sub-floor by the
appropriate methods. Clean and abrade surfaces to remove any sealers or surface treatments to insure a good adhesive
bond. Loose tiles must be re-adhered to the sub-floor, and grout joints that exceed 1/16" must be filled with a leveling
compound. Follow the manufacturer’s recommendation for applying the leveling compound. Any area containing the
leveling compound must be completely dry before proceeding with the installation of the wood floor. Perform appropriate
moisture tests.
STEP 8: INSTALLING THE FLOOR
Helpful Tips
■
Remove flooring from several different cartons to maximize color and shade mixture.
■
Stagger the ends of boards at least 6" in adjacent rows.
■
Installation parallel to the longest wall provides best visual effect.
Doorway and Wall Preparation
Undercut or notch-out door casings 1/16" higher than the thickness of the flooring being installed to avoid difficult scribe cuts
during installation. Also remove existing base and shoe molding as well as doorway thresholds; each can be replaced after
installation is complete.
Establish Starting Point
An exterior wall is usually the straightest and best reference line to start the installation. Direction of finished flooring should
be at right angles to the floor joists whenever possible. Establish a starting line by leaving a minimum 1/2" expansion gap*
around all vertical obstructions. Measure this distance from the starting wall (in at least two places) close to the starting wall’s
opposite corners. Mark these points and snap a working chalk line parallel to the starting wall allowing the required
expansion space between the starting wall and the edge of the first row of flooring.
* Large spans in environments of possible high humidity may require the addition of internal or field expansion to minimize
the possibility of cupping and/or buckling. This can be accomplished by using spacers, such as small washers, every 10-15
rows inserted above the tongue and removed after several adjoining rows have been stapled or glued.
