Why is moisture testing important before floor covering installation?

Moisture testing is critical before floor covering installation primarily to ensure proper adhesive bonding. Excess moisture in the subfloor can negatively affect how adhesives perform. If the moisture levels exceed acceptable limits, it could prevent the adhesive from curing properly, leading to poor adhesion of the flooring material. This could cause the flooring to lift, buckle, or have other structural issues that compromise its integrity over time.

While other factors such as material quality, project timelines, and warranty compliance may have their importance, they do not directly address the immediate technical necessity of assessing moisture levels for adhesive bonding. Proper adhesion is the cornerstone for a successful floor covering application, meaning adequate moisture testing can prevent significant issues that stem from improper bonding, ensuring the longevity and durability of the installed flooring.
