What Causes Bubbles in Laminate Flooring?
Bubbles in laminate flooring typically result from moisture, improper installation, or issues with the subfloor. Here are some of the most common reasons:
1. Moisture Damage
Excess moisture is one of the biggest enemies of laminate wood flooring. Spills, high humidity, or leaks can cause the fiberboard core to swell, leading to bubbling. If water seeps between the seams, it can break down the adhesive and weaken the planks.
2. Improper Laminate Flooring Installation
If the planks aren’t installed correctly, bubbles can form over time. Common mistakes include:
- Failing to leave enough expansion space around the edges
- Using too much or too little adhesive
- Not acclimating the planks before installing laminate flooring
3. Subfloor Issues
A damaged or uneven subfloor can create pressure points, causing the laminate to lift and bubble. Before starting laminate floor installation, ensure the subfloor is clean and dry at a high level.
4. Trapped Air During Installation
Failure to press down properly when using adhesive-based laminate flooring can trap air bubbles under the surface. Over time, these air pockets expand, creating visible bumps.
How to Fix Bubbling in Laminate Flooring
The good news is that, in many cases, you can fix bubbling without replacing the entire floor. Here’s how:
1. Address Moisture Problems
If moisture is the issue, locate the source and fix it immediately. Use a dehumidifier to reduce indoor humidity levels and clean up spills promptly.
2. Relieve Expansion Pressure
If bubbling occurs near walls or doorways, the flooring may not have enough space to expand. Carefully remove the molding and trim a small portion of the planks to create the necessary gap.
3. Replace Damaged Planks
For severe bubbling, the best solution may be to replace individual planks. If you installed a floating laminate flooring system, you can remove the affected pieces and install new ones. Match the existing design and follow proper laminate flooring installation techniques.
4. Use an Injection Method
For minor bubbling, try injecting adhesive under the raised area using a syringe and then weighting it down with a heavy object until it dries. This method can help flatten the floor without removing planks.
