Understanding Laminate Flooring: What Is It?

Laminate flooring is a popular, cost-effective alternative to hardwood that offers durability and stylistic versatility. It consists of multiple layers fused together, including a moisture-resistant backing, a core layer, a photographic image of natural materials, and a protective top wear layer.

Thanks to its layered construction, laminate flooring resists scratches and dents better than many natural floor types. However, it is sensitive to environmental changes, making acclimation an important part of the installation process.

What Does Acclimation Mean For Laminate Flooring?

Acclimation is the process of allowing laminate flooring materials to adjust to the temperature and humidity conditions where they’ll be installed. This helps the planks reach moisture balance with the surrounding air, minimizing expansion, contraction, or other material stress after installation.

During shipping and storage, laminate is exposed to varying climates. If installed immediately in a drastically different environment, planks may warp or create gaps as they adjust post-installation.

Does Laminate Flooring Need To Acclimate? Industry Insights

Yes, laminate flooring must acclimate before installation. Most major flooring manufacturers, such as Pergo, Shaw, and Mohawk, state acclimation is mandatory or strongly recommended. This is not just a best practice—it is often a warranty requirement.

Ignoring acclimation may result in product failure, visible defects, or voided warranties. Even “water-resistant” or “quick-install” laminates need acclimation for best results.

Potential Problems If Laminate Flooring Isn’t Acclimated

• Buckling: Planks swell and press against each other, raising from the subfloor.
• Gapping: Shrinkage creates unsightly spaces between boards.
• Warping/Cupping: Edges of planks lift or dip, causing uneven surfaces.
• Delamination: Layers separate from each other due to internal tension.
• Warranty Issues: Most manufacturer warranties exclude damage from improper acclimation.

Acclimation is a simple step that prevents these expensive, frustrating problems.

Manufacturer Guidelines On Laminate Flooring Acclimation

Most manufacturers recommend acclimating laminate flooring for at least 48–72 hours in its intended environment. However, the specifics can vary:

Brand	Acclimation Time	Additional Notes
Pergo	48 hours	Flat on floor, leave packaging loosely open
Shaw	48–72 hours	Boxes stacked flat, in installation area
Mohawk	48 hours	Allow airflow, room at typical living conditions
Other Brands	24–72 hours	Always check product guidelines

How To Acclimate Laminate Flooring: Step-By-Step Guide

Proper acclimation is straightforward if basic steps are followed.

1. Prepare The Room:
   • Heating/cooling systems should run as they will when the space is occupied.
   • Maintain 60–85°F temperature and 35%–65% relative humidity.
2. Place Flooring Boxes Properly:
   • Lay unopened boxes flat in the room where flooring will be installed.
   • Do not store directly on concrete or stack more than 3–4 high for airflow.
3. Allow Full Acclimation:
   • Leave flooring for 48–72 hours as per manufacturer’s instructions.
   • If packaging is plastic-wrapped, slit open ends for better airflow if recommended.
4. Check Environmental Conditions:
   • Use a hygrometer to confirm room is within required temperature/humidity range.
5. Inspect Planks Before Installation:
   • Examine boards for visible damage, warping, or defects before starting.

What Happens If You Skip Acclimating Laminate Flooring?

Skipping acclimation is a leading cause of post-installation issues. Floors may expand or contract substantially once installed, resulting in raised edges, separation, or noise. These developments often emerge weeks or months later, leading to expensive repairs.

Even in climates with low humidity swings, acclimation helps ensure boards are at equilibrium with the specific home environment, not just the supplier warehouse.

How Long Should Laminate Flooring Acclimate?

The recommended acclimation period for most laminate flooring is 48–72 hours. If the climate is especially humid or dry, a full 72 hours is safest. Never reduce this time, even if products claim faster installation.

For projects in recently renovated rooms, or after periods of unusual weather (extreme rain or drought), consider extending acclimation by another 24 hours for maximum safety.

Can Humidity And Temperature Affect Laminate Acclimation?

Yes, both temperature and humidity have a direct effect on laminate flooring’s behavior during and after acclimation. Laminate core materials absorb and release moisture depending on the room’s environment. Too much moisture can cause swelling; too little can result in shrinkage and gapping.

Using a dehumidifier or humidifier may help stabilize conditions in regions with extreme seasonal swings, ensuring the best possible outcome for your flooring installation.

Tips For A Successful Laminate Flooring Acclimation And Installation

• Always follow the manufacturer’s acclimation instructions specific to each product.
• Inspect and record room temperature and humidity before and during acclimation.
• Acclimate flooring in the same room and on the same level where it will be installed.
• Never store laminate planks in basements or unconditioned spaces prior to installation.
• Keep airflow around boxes; do not cover with plastic, which can trap moisture.
• Do not unbox flooring unless manufacturer approves; sometimes airflow is best achieved with sealed cartons.
• Use moisture barriers as recommended for installations over concrete slabs or below-grade locations.

Laminate Acclimation Myths Versus Facts

Myth	Fact
No need to acclimate in dry climates.	Acclimation is necessary in all climates; even dry air can cause gapping.
Acclimation isn’t required if installation is fast.	Quick installs do not replace acclimation; sanding or repairs may be needed later.
Leaving boxes for a few hours is enough.	Minimum of 48 hours is required for full adjustment.
Opening boxes helps acclimation.	Only open per manufacturer guidelines; sometimes sealed boxes are preferred.

Seasonal Considerations In The U.S.

Seasonal swings in humidity and temperature across the United States have a major impact on laminate flooring acclimation. In Northern regions, extreme winters can dry indoor air, while Southern states face high humidity.

Plan installations during stable weather periods and control indoor heating/cooling for consistent results. In new homes, wait to install flooring until HVAC is up and running for at least two weeks to avoid surprises.

Acclimating Laminate Over Different Subfloors

The type of subfloor—concrete, wood, or radiant heat—affects acclimation practice for laminate flooring. Over concrete or in basements, ensure proper vapor barriers are in place. Acclimate both flooring and underlayment in the installation space before starting the project.

For radiant heat, follow specific guidelines for gradual temperature changes and verify with the flooring and heating system manufacturers for best results.

The Cost Of Ignoring Acclimation

• Voided Product Warranty: Manufacturers will not cover claims if acclimation protocols are ignored.
• Repair And Replacement Costs: Hiring contractors to fix warping or replace damaged boards can be expensive.
• Reduced Home Value: Poorly installed laminate with visible defects may lower home resale value.
• Time Wasted: Rushed projects can result in delays and rework, nullifying any time saved up front.

Frequently Asked Questions About Laminate Flooring Acclimation

Can Laminate Flooring Be Installed Immediately After Delivery?

No, flooring should never be installed immediately after delivery. The material needs time to stabilize with its new environment before being fixed in place.

Can I Stack Laminate Boxes In The Garage Or Basement To Acclimate?

No, only acclimate in the actual installation room under “living” conditions. Garages and basements often experience temperature and moisture swings.

Does Acclimation Time Vary For Different Thicknesses?

Thicker laminate often needs the full 72 hour period to fully acclimate, though most standard planks follow the same 48–72 hour rule. Always check the box for specifics.

Is It Ok To Walk On Laminate During Acclimation?

Limit foot traffic on boxes during acclimation. Walking on loose planks may cause damage or create minor warping before installation.

How Can I Tell If Flooring Has Fully Acclimated?

Planks should feel stable and consistent in size. A moisture meter can verify equilibrium between laminate and the subfloor, though this is typically not required for standard installations.

Best Practices For Professional And DIY Installers

• Read the full installation manual before starting the project.
• Document acclimation (date, time, room conditions, photos) in case of warranty claims.
• Check for special conditions if installing in kitchens, bathrooms, or basements.
• Consult with product reps or technical support for job-specific recommendations.
