Unexpected bumps underfoot often signal trapped air or moisture infiltration beneath your planks. Spotting such raised areas early helps you decide if a quick DIY fix or a professional board replacement is needed. Maintaining a flat, wood-look surface depends on identifying the specific cause—ranging from installation errors to humidity spikes—before the damage spreads across the room.
What Causes Bubbles in Laminate Flooring?
Bubbles in laminate flooring can form for several reasons, including moisture issues, poor installation, and temperature fluctuations. Here are some of the most common culprits:
1. Moisture Exposure
Water is the enemy of laminate flooring. If moisture seeps into the core of the planks, it can cause swelling, leading to bubbles and warping. This can happen due to spills, high humidity, or improper cleaning.
2. Poor Laminate Flooring Installation
A rushed or improper laminate flooring installation can lead to air pockets and bubbles. If the planks are not acclimated adequately before installing laminate flooring, they may expand or contract, causing the surface to lift. Additionally, failing to leave an expansion gap around the edges of the floor can lead to pressure buildup, resulting in bubbling.
3. Trapped Air Pockets
During laminate floor installation, if the underlayment is not laid correctly or the adhesive is applied unevenly (for glue-down laminate), air pockets can form, causing bubbles to appear over time.
4. Extreme Temperature Changes
Laminate flooring is sensitive to temperature fluctuations. If exposed to excessive heat or cold, the planks can expand or contract, creating gaps or bubbles. This is especially common in rooms with direct sunlight or areas near heating vents.
How to Fix Bubbles in Laminate Flooring
1. Address Moisture Problems
If moisture is the cause, it’s essential to dry out the affected area. A dehumidifier can help reduce humidity levels in the room. If water damage is severe, replacing the bubbled planks may be necessary.
2. Roll Out Air Pockets
For minor bubbles caused by trapped air, a rolling pin or heavy object can help press the flooring back into place. Apply even pressure over the affected area to smooth it out.
3. Make Small Cuts for Trapped Air
If the bubble is persistent, you can carefully cut a small slit in the centre of the bubble using a sharp utility knife. Then, apply wood glue underneath, press it down, and place a heavy object on top until it dries.
4. Replace Damaged Planks
The best solution is to replace the affected planks for severe bubbling that cannot be repaired. Many laminate wood flooring options feature a click-lock design, making removing and replacing damaged boards easier.
5. Prevent Future Bubbling
Follow proper laminate flooring installation techniques to avoid bubbling in the future. Ensure the planks acclimate to the room before installing laminate flooring, use a moisture barrier in high-humidity areas, and maintain a stable indoor climate to minimise expansion and contraction.
