Subfloor adhesives: Safe footing guaranteed!

When installing flooring in your home or cottage, a quality subfloor adhesive can make a real difference in ensuring longevity and stability. Read on for the fundamentals of subfloor construction adhesives.

What are subfloor adhesives?

The strength and solidity of floors are essential components of any building. When installing flooring, a subfloor adhesive is applied below the panels to secure them at the panel-to-joist connection, minimizing squeaks and preventing uneven flooring. A subfloor adhesive must be strong enough to remain durable over time, but also provide enough elasticity to absorb the regular movement, impact, and potential shrinkage most floors face.

How to use subfloor adhesive

Applying a subfloor adhesive when installing flooring makes a huge difference when it comes to the strength and resilience of your floor. Follow these basic steps and enjoy level, noise-free floors.

As with all strong adhesives, take safety precautions when using subfloor adhesives. Wear gloves, work in a well-ventilated area, and wash hands after use.

Like most adhesives, subfloor adhesives work best when at the right temperature. Check your products’ specifications to determine ideal conditions. 

Surfaces to be bonded should be thoroughly cleaned of any dust, grease, particles, or contaminants. Before starting application, pre-fit all materials and panels.

To apply, use a caulking gun. Apply the adhesive in a steady flow to joists or studs, moving in a zigzag pattern to ensure all edges are adequately coated. Lower the subflooring panel onto the joists and join surfaces within 15 minutes. If repositioning is necessary, do so within approximately 30 minutes.

Clean tools and any residue immediately with mineral spirits or paint thinner. Any unwanted cured adhesive can be chiseled away with a sharp-edged tool, taking care not to damage surfaces.

When installing floors yourself, be sure to consult your local building codes for requirements such as fastener spacing, size, and type. When in doubt, refer to your design professional’s specifications.
