  1. What is the minimum recommended acclimation period for solid hardwood flooring before installation in most US climate conditions?

    Answer: 3–5 days

    Solid hardwood should acclimate in the installation environment for at least 3–5 days to minimize expansion or contraction after installation.

  2. Which nail type is the industry standard for blind-nailing solid 3/4-inch hardwood flooring?

    Answer: 15.5-gauge cleat nail

    15.5-gauge cleat nails are the CFI-recommended fastener for blind-nailing 3/4-inch solid hardwood because they hold firmly without splitting the tongue.

  3. What expansion gap is required around the perimeter when installing solid hardwood flooring?

    Answer: 3/4 inch

    A 3/4-inch expansion gap around the perimeter allows solid hardwood to expand and contract with seasonal humidity changes without buckling.

  4. Engineered wood flooring can typically be installed at or below grade because its cross-ply construction:

    Answer: Reduces expansion and contraction from moisture

    The cross-ply construction of engineered wood limits dimensional movement caused by moisture, making it suitable for below-grade or on-grade installations.

  5. When face-nailing the first row of solid hardwood flooring, nails should be placed:

    Answer: 1 inch from the wall edge through the face

    The first row is face-nailed approximately 1 inch from the wall edge so the nail heads will be hidden by the base molding.

  6. What minimum wood moisture content difference between the hardwood flooring and the subfloor does CFI recommend investigating before installation?

    Answer: 4%

    CFI guidelines indicate that a moisture content difference greater than 4% between the hardwood and subfloor warrants investigation and corrective action before installation.
