4 Main Causes of Contraction in Laminate Flooring and Ways to Prevent it

Author : Lamiwood Floors | Published On : 10 Jan 2024

Laminate flooring is a popular choice for many homeowners because it's durable, affordable, and looks great. However, like any flooring, laminate can face issues, and one common concern is contraction. To ensure your laminate flooring lasts, it's important to know why contraction happens and how to prevent it. Let's explore the four main reasons for contraction and simple ways to keep your laminate floors in top shape.

  1. Moisture Imbalance

The primary cause of contraction in laminate flooring is moisture imbalance. Laminate is made of wood fibers and resin layers, and changes in moisture levels can make it expand or contract. Too much moisture causes expansion, while low humidity levels lead to contraction, resulting in visible gaps between the planks.

  • Prevention Tip

Maintain consistent humidity levels by using a dehumidifier in humid areas and ensuring good ventilation in drier spaces. During installation, use a moisture barrier under the laminate to protect against moisture issues.

  1. Poor Installation

Improper installation is another culprit for contraction issues. If the planks aren't acclimated before installation or are spaced incorrectly, it can lead to problems later on. Inadequate expansion gaps and improper spacing prevent the laminate or herringbone flooring from adjusting to the room's conditions, causing contraction.

  • Prevention Tip

Let the laminate planks sit in the room for at least 48 hours before installation. Ensure proper spacing by following the manufacturer's guidelines, allowing for expansion gaps around edges and obstacles during installation.

  1. Subfloor Problems

The condition of the subfloor directly affects laminate flooring performance. Uneven or damaged subfloors can stress the laminate, leading to contraction. If the subfloor isn't prepared properly, irregularities can cause warping and contraction over time.

  • Prevention Tip

Thoroughly inspect and prepare the subfloor before installation. Use a leveling compound to create a smooth surface, and consider installing a quality underlayment for extra support and insulation.

  1. Temperature Changes

Extreme temperature fluctuations can harm laminate flooring. Sudden temperature changes, especially in areas like basements or poorly insulated rooms, can cause the material to contract, resulting in gaps between planks.

  • Prevention Tip

Maintain a consistent temperature in your living space. Use rugs or carpets in high-risk areas to regulate temperature and consider heating and cooling systems that provide gradual temperature changes.

 

Preserving your laminate flooring's beauty and longevity involves a proactive approach to prevent contraction.. Following these simple tips and practicing proper maintenance will enhance your satisfaction with your laminate flooring investment.
