Choosing the Right Adhesive for Moisture Control

The success of any flooring installation relies heavily on the selection of the appropriate adhesive. Moisture control is paramount, particularly with hardwood floors, where excessive moisture can lead to warping, buckling, and other costly repairs.

Understanding Moisture

Before selecting an adhesive, one must understand the level of moisture present in the substrate. Acceptable moisture readings for hardwood floors range between 4% to 6%. Higher readings indicate excess moisture that needs to be addressed prior to installation.

Types of Adhesives

Water-based Adhesives

• Low VOC (Volatile Organic Compounds), environmentally friendly.
• Easy to apply and clean up.
• Not suitable for areas with high moisture levels.

Solvent-based Adhesives

• Stronger and more water-resistant than water-based adhesives.
• Higher VOCs, requiring proper ventilation during application.
• May cause discoloration of some floor finishes.

Moisture-cured Urethane Adhesives

• Excellent moisture resistance, making them ideal for areas with high humidity.
• Permanent bonding, providing long-lasting durability.
• More expensive than other types of adhesives.

Selecting the Right Adhesive

The selection of the right adhesive depends on the moisture level of the substrate, the type of flooring being installed, and the specific installation requirements. It is recommended to consult with an experienced flooring professional to determine the best adhesive for each situation.

Additional Considerations

• Use a moisture meter to accurately determine the moisture level in the substrate.
• Follow the manufacturer’s instructions for proper application and curing times.
• Allow sufficient time for the adhesive to cure before exposing it to moisture.

By carefully considering these factors, you can ensure that the right adhesive is selected for your hardwood flooring installation, resulting in a durable and moisture-resistant floor that will provide years of enjoyment.
