Common Reasons for Bubbles in Laminate Wood Flooring
1. Moisture Issues: Moisture is one of the biggest culprits. If water seeps beneath the laminate planks, it can cause swelling or bubbling. This can happen due to spills, excessive humidity, or improper moisture barriers during laminate flooring installation.
2. Poor Installation: Bubbles can also appear if poor artistry is used to install laminate flooring. This includes failing to leave enough expansion gaps or improper adhesive use in glue-down styles.
3. Subfloor Problems: An uneven or damaged subfloor can form air pockets beneath the laminate. These pockets can expand with foot traffic or temperature changes, leading to noticeable bubbles.
4. Delamination: Delamination occurs when the top layer of the laminate separates from the rest. Poor-quality materials or manufacturing defects often cause this.
How to Fix Bubbles in Laminate Flooring
1. Identify the Source: Before you fix the bubble, determine whether it’s caused by moisture, installation error, or structural issues. Solving the root problem prevents it from recurring.
2. Replace Affected Planks: The best way to resolve bubbling is to remove and replace the damaged planks. Floating floors can often be done without disturbing the entire floor.
3. Use a Roller for Minor Bubbles: If the bubble is minor and caused by air, gently rolling over the area with a heavy roller can sometimes fix the issue. This works best with freshly installed laminate.
4. Repair Adhesive Separation: If bubbles are due to adhesive failure, reapplying glue beneath the bubbled area using a syringe and placing a weight on top until dry can help.
How to Prevent Bubbles During Laminate Floor Installation
Preventing bubbles starts with proper laminate floor installation:
- Acclimate your laminate planks to the room’s temperature and humidity
- Use a vapor barrier if installed over concrete.
- Ensure your subfloor is level and clean.
- Leave the appropriate expansion gaps around the room perimeter.
- Hire experienced professionals from a trusted laminate flooring store.
