Mullican Hardwood Floor Installation


Engineered Stapled Floors Or Glue Direct

TOOLS

Staple down using 1 1/4” to 1 1/2” staples depending on product. 18 gauge, 3/16” Crown staples. Do not use staples or nails intended for 3/4” solid flooring.

Wood type subfloors should also be checked for moisture using a reliable moisture meter. Wood or plywood subfloors should not exceed 14% moisture content, the moisture content difference between hardwood flooring and subfloor should not exceed 4%. Check with your local distributor for your geographical variances.

SUBFLOOR

5/8” minimum thickness, preferred 3/4” or thicker plywood installed with long edges at a right angle to the 16” on center floor joists and staggered so that the end joints in adjacent panels break over different joists. Nail at each bearing with 6d threaded or 8d common nails spaced 10” on center along intermediate joists.

Solid Hardwood

SUGGESTED TOOLS AND ACCESSORIES

Nailer or Stapler: For installation over 3/4” wood type sub-floors installed over joist or truss systems a minimum 1 3/4” or 2” long cleat, or staple should be used. Use only nailers or staplers designed for installation of 3/4” hardwood floors. 3/4” thick plywood over concrete, 1 1/2” cleats or stapler should be used. See NWFA installation guideline for details. High moisture areas. Room larger than 20 ft. by 20 ft. 1/32 aluminum spacers may be needed for expansion as well as 3/4” at any
vertical obstruction. i.e. walls. Mullican recommends prefinished foot for manual and
air nailers/staplers.

HANDLING AND STORAGE

Flooring must be protected from adverse moisture conditions during the transportation as well as the storage of the material. The material must be stored at least 4” or more off the ground and stored in a dry area. This practice will prevent a significant change in the moisture content. Open the cartons and allow flooring to acclimate. Follow NWFA guideline for acclimation on job site! See general instructions below.

Preparation of Subfloor

Subfloor irregularities and undulation may cause any wood flooring installation to
develop hollow spots between the flooring and subfloor. These hollow spots are NOT the result of any wood floor manufacturing defect and are NOT covered by the
Mullican Flooring warranty.

Thoroughly Clean Subfloor

Remove paint, wax, oil, plaster, “sheetrock mud” and other foreign materials, as well as obvious surface irregularities. #3-1/2 grit open coat paper or equal may need to be used to grind a concrete subfloor. This will loosen any dirt, loose concrete or contaminants. Sweep or vacuum thoroughly. All previous or existing glues or adhesives must be removed before installing new hardwood flooring.
