Installing solid hardwood flooring is an exciting step in upgrading your home, but the key to a flawless finish often comes before you lay a single plank. Proper acclimation of your solid hardwood flooring is essential to prevent gaps, warping, squeaks, or long-term damage. Acclimation allows the wood to adjust to your room’s humidity levels and temperature, ensuring your floors stay stable and beautiful for years to come.
If you’re wondering how to acclimate solid hardwood flooring, this guide will walk you through the process, including tips on climate control, monitoring moisture content, and maintaining proper humidity levels.
What Is Acclimation of Solid Hardwood?
Acclimation is the process of allowing your solid hardwood flooring to adjust to the temperature and humidity levels of the room where it will be installed. Because hardwood is a natural material, it expands and contracts depending on moisture in the air.
By letting your wood reach its equilibrium moisture content (EMC), you can avoid post-installation problems such as gaps, buckling, or shrinking. Typically, solid hardwood should acclimate for 48–72 hours, but thicker boards or varying climates may require extra time.
Why Acclimation Matters
Solid hardwood is more sensitive than engineered wood because it consists of a single piece of wood. It absorbs moisture from the environment and responds to changes in humidity levels and temperature. Proper acclimation ensures the flooring:
Prevents Shrinkage and Expansion
Without acclimation, boards can shrink in dry conditions or expand when exposed to excess moisture, leading to gaps or warped planks.
Reduces Long-Term Damage
Incorrect moisture content can cause cracks, checks, or other structural problems over time.
Ensures Stability
Acclimation allows the floor to settle in the environment, minimizing squeaks and movement caused by subfloor shifts.
How to Acclimate Solid Hardwood Flooring: Step-by-Step
Step 1: Store Hardwood in the Installation Area
Move your solid hardwood planks into the room where they will be installed. This helps them adjust to the same humidity levels and temperature they will experience post-installation.
Unbox and Open the Planks: Remove the packaging to allow air circulation around each plank. Avoid leaving them sealed in plastic.
Cross-Stack the Boards: Stack planks in a cross-stacking pattern a climate control, moisture content, humidity levels few inches off the ground to maximize airflow. Use shims or blocks for elevation.
Step 2: Monitor Climate Control
Proper climate control is essential during acclimation. Fluctuating temperature and humidity can negatively affect solid hardwood.
Use a Thermo-Hygrometer: Monitor both temperature and humidity levels. Aim for 35–55% relative humidity and temperatures around 60°F–80°F.
Adjust Humidity if Needed: Use a humidifier in dry rooms or a dehumidifier in high-moisture environments to stabilize the conditions.
Step 3: Allow Acclimation Time
The acclimation period depends on plank thickness, wood species, and initial moisture content.
Check Moisture Content: Use a moisture meter to ensure the wood and subfloor are at compatible levels.
Prepare the Subfloor: Make sure it is clean, dry, and level. For concrete subfloors, moisture testing is critical to prevent future damage.
Step 4: Ensure Proper Air Circulation
Good airflow is crucial for uniform acclimation.
Use Fans: Circulate air around the planks without directing fans straight at the wood.
Avoid Sunlight: Keep boards away from vents or direct sunlight to prevent uneven drying and warping.
Common Acclimation Issues
Even with care, some problems can arise during acclimation:
Excess Moisture and Warping – Use a dehumidifier if the room is too humid.
Drying Out and Shrinking – Keep humidity stable to prevent gaps between planks.
Inconsistent Acclimation – Ensure planks experience the same conditions as the installation room.
Installing Your Acclimated Hardwood Flooring
Once acclimated, follow these basic installation steps:
Prepare the Subfloor – Ensure it is dry, level, and clean.
Lay the First Row – Leave an expansion gap along the walls.
Secure Planks – Use a flooring nailer or stapler according to the manufacturer’s instructions.
Continue Installation – Lock each plank in place and use a tapping block to prevent edge damage.
Finishing Touches – Trim edges and install baseboards to cover expansion gaps.
Caring for Your Hardwood Floors
Proper care maintains stability and appearance:
Regular Cleaning: Sweep or vacuum to remove dirt. Use a microfiber mop for deeper cleaning.
Avoid Excess Moisture: Wipe spills immediately and use rugs in high-traffic areas.
Maintain Humidity Levels: Consistent humidity levels prevent expansion or shrinkage. Use humidifiers or dehumidifiers as needed.
