How to Avoid Hollow Spots in Glued-Down Floors

Buildix logo with Building Materials Intel Hub text

Hollow spots are one of the most common complaints in glued-down flooring installations. Whether it’s hardwood, engineered wood, or resilient flooring, these voids beneath the surface create an audible “click” or “drum” sound underfoot and can lead to long-term performance issues.

For Buildix ERP users managing flooring projects across Canada, avoiding hollow spots means implementing the right materials, methods, and monitoring systems to ensure consistent, defect-free results.

What Causes Hollow Spots?

✅ Inconsistent Adhesive Coverage

Uneven troweling or using the wrong trowel notch leaves gaps in adhesive layers.

✅ Substrate Irregularities

High or low points in the substrate prevent full contact between adhesive and flooring.

✅ Environmental Conditions

Humidity swings and temperature extremes can cause adhesives to skin over too quickly, preventing proper bonding.

✅ Premature Traffic

Allowing foot traffic or furniture placement before adhesives fully cure can break bonds and create voids.

Risks of Hollow Spots

Structural Integrity: Weakened bonds can lead to plank movement or lifting.

Acoustic Issues: Unwanted noise with every step.

Moisture Intrusion: Voids provide pathways for moisture, potentially leading to mold or subfloor damage.

Best Practices to Prevent Hollow Spots

1. Substrate Preparation

Ensure subfloors are clean, dry, and level within manufacturer tolerances.

Perform moisture testing and remediate high RH conditions before installation.

3. Monitor Open and Working Times

Apply flooring within the adhesive’s working time to prevent skinning over.

Use Buildix ERP to set timers and alerts for crews on large job sites.

4. Roll the Floor Properly

Use a flooring roller immediately after placement to press flooring firmly into adhesive and remove air pockets.

5. Allow Proper Cure Time

Restrict traffic on newly installed floors until adhesives achieve full cure strength.

Buildix ERP can log cure times and notify teams when areas are safe for use.
