The 48-Hour Rule: Why Acclimation is Key to a Perfect Laminate Installation

Picture this. The new boxes of planks arrive, the old floor is gone, and every part of you wants to start clicking boards into place that same afternoon. It is one of the most exciting moments of any remodeling project, and the temptation to rush is completely understandable.

Here is the small secret that separates a floor that looks flawless for years from one that buckles by spring. The planks need time to settle into your home first. We at Marshall Flooring have spent years helping homeowners across Cleveland, Cleveland Heights, Pepper Pike, and Chagrin Falls get this part right, and our laminate flooring selection always comes with the same friendly reminder: give it 48 hours.

Why your floor needs to breathe before installation

Laminate is built around a wood-based core, and like real wood, it responds to the air around it. When planks travel from a warehouse to a delivery truck to your living room, they pass through very different levels of temperature and humidity along the way.

If you install them before they adjust, the boards keep changing shape after they are locked down. That movement is what leads to gaps in dry months and buckling in humid ones. The same principle applies to hardwood, which is exactly why acclimation has been standard practice for natural wood floors for decades.

The 48-hour rule explained simply

Acclimation means letting your flooring sit inside the actual room where it will live, so it can reach the same temperature and moisture level as that space. Most laminate manufacturers ask for a minimum of 48 hours, and that window is worth respecting every single time.

The goal is balance. Once the planks match the conditions of your home, they stay stable underfoot for the long haul.

Best practices to remember during acclimation

A few simple habits make all the difference during those two days. Keep these in mind and your installation will thank you later.

  1. Bring the boxes into the actual installation room, not a garage, basement, or covered porch.
  2. Lay the boxes flat and avoid stacking them too high, so air can reach every plank.
  3. Keep your home at normal living temperature and humidity, the same as it will be day to day.
  4. Leave the planks in their sealed packaging unless your manufacturer says otherwise.
  5. Wait the full 48 hours, even when everything looks ready to go sooner.

When moisture deserves extra attention

Some spaces ask a little more of your flooring than others. Kitchens, laundry rooms, and finished basements all carry higher humidity, and that changes the conversation around acclimation.

In those rooms, the subfloor matters just as much as the planks, since trapped moisture underneath can undo even a perfect installation. This is where waterproof flooring often becomes the smarter long-term choice, giving you peace of mind in areas where spills and steam are simply part of life.

When you plan ahead for both acclimation and moisture, you set your floor up to look beautiful for many years to come.
