  • Ensure the adhesive glue is suitable for laminate flooring.

Common Mistakes to Avoid

1. Using Too Much Adhesive

Reason: Excess adhesive can seep up through the seams and create unsightly bubbles.
Solution: Use a minimal amount of adhesive, spreading it evenly and thinly.

2. Improper Acclimation of Flooring

Reason: Flooring not allowed to acclimate to the room's temperature and humidity can expand and contract unevenly, leading to bubbling.
Solution: Acclimate the laminate flooring in the room for at least 48 hours before installation.

3. Ignoring Underlying Subfloor Issues

Reason: Uneven or damaged subfloors can cause the laminate to buckle and bubble.
Solution: Ensure the subfloor is clean, dry, level, and free of any debris or imperfections before installation.

FAQs

What kind of adhesive should I use to fix laminate bubbles?
Use a construction adhesive specifically designed for laminate flooring. Avoid using anything that could damage the laminate surface or cause discoloration.
