Understanding Engineered Hardwood Flooring

Hardwood is a natural material that responds to moisture and temperature changes. Whether you’re installing solid hardwood or site-finished boards, accurate preparation and consistent technique are essential.
Correct acclimation and moisture testing are critical prior to installation.

Pre-Installation Checklist

Good installation starts long before the first nail:

Inspect the Material

Check all boards for defects or irregularities before installation. Do not install damaged pieces.

Conditioning & Acclimation

Hardwood should be stored in the installation area for a minimum period to allow the wood to reach equilibrium moisture content with the room environment. Proper acclimation minimizes expansion and contraction after installation.

Testing and Preparing Subfloors

• Subfloors must be level, clean, and structurally sound.

• Use a moisture meter to confirm levels are within acceptable manufacturer tolerances before proceeding.

• Concrete subfloors require a moisture barrier.

These steps ensure that your hardwood performs as intended without future issues like gapping or cupping.

Planning Your Layout

Before nailing begins:

• Decide on the board direction, often parallel to the longest room dimension or natural light source.

• Snap chalk lines to keep the first rows straight.

• Maintain proper expansion gaps around all perimeter and fixed objects.

Hardwood Installation Techniques

Nail or Staple Installation

For most traditional engineered hardwoods over wood subfloors:

• Use approved flooring nails or staples at specified intervals.

• Drive fasteners at the correct angle to secure boards without splitting.

Glue-Down Installation

Approved adhesives may be used with engineered hardwood on appropriate subfloors, following manufacturer instructions.

Staggering Joints

To create stability and visual appeal:

• Stagger end joints at least several inches apart.

• Avoid repeated patterns, random offsets improve the overall look..

Finishing Touches

Once boards are secure:

• Install baseboards and quarter round to cover expansion gaps.

• Inspect the floor visually and listen for any loose boards.

Never overlook small details; proper finishing protects your investment and enhances aesthetics.

Why Following Manufacturer Instructions Matters

While general installation methods apply across many projects, manufacturer-specific instructions ensure you meet product requirements and maintain warranties. Always refer to the official manual for precise fastener patterns, adhesive recommendations, and site conditions.
