How long should flooring be stored in the building before being laid to permit acclimation?

Acclimation of flooring materials is a crucial step in ensuring that they adjust to the indoor environment before installation. This process allows the materials to adapt to the humidity and temperature of the building, which helps prevent problems such as warping, buckling, or gaps after installation.

The recommended time for acclimation varies depending on the type of flooring and the conditions of the environment. Storing the flooring for 4 or 5 days generally provides a balanced adjustment period. During this time, the flooring can adjust properly to the moisture content in the air, which is typically sufficient for most flooring types like hardwood or laminate.

A shorter period, such as 3 days, may not allow sufficient time for acclimation, especially in environments with fluctuating temperatures and humidity levels. Meanwhile, lengths such as 1 week or 2 weeks could provide more acclimation time than is necessary, potentially leading to issues with the flooring settling or conforming too much to the moisture levels, which might complicate installation timing. Thus, the 4 or 5 days recommended aligns well with industry best practices to ensure a successful installation.
