Laminate flooring has become a popular choice for homeowners due to its durability, affordability, and ease of installation. However, just like any other type of flooring, laminate flooring is not immune to damage. One common issue that homeowners face is a bubble in their laminate flooring. This can be caused by a variety of factors such as improper installation, moisture, or uneven subfloor. In this article, we will guide you through the steps on how to fix a bubble in your laminate flooring.

Understanding the Cause of Bubbles

Before we dive into the steps on how to fix a bubble in your laminate flooring, it’s important to understand what causes these bubbles to form. Laminate flooring is made up of several layers, including a moisture-resistant backing layer, a high-density fiberboard core, a design layer, and a protective wear layer. When moisture seeps through the seams or edges of the flooring, it can cause the fiberboard core to swell and push against the other layers, creating a bubble.

Other factors that can contribute to the formation of bubbles include improper installation, uneven subfloor, or inadequate acclimation of the flooring to the environment. It’s important to address the root cause of the problem to prevent future bubbles from forming.

Necessary Tools and Materials

To fix a bubble in your laminate flooring, you will need the following tools and materials:

  • Drill with a 1/8 inch bit
  • Syringe or adhesive injector
  • Wood glue or epoxy adhesive
  • Weight or heavy object
  • Hammer
  • Pry bar
  • Utility knife
  • Screwdriver
  • Replacement baseboards

Steps on How to Fix Bubble in Laminate Flooring

Now that you have the necessary tools and materials, here are the steps on how to fix a bubble in your laminate flooring:

1. Identify the Location of the Bubble

The first step is to locate the bubble in your flooring. Look for any visible bulges or unevenness on the surface of the flooring. Once you have identified the location of the bubble, mark it with a piece of tape or a marker.

2. Remove the Baseboards

To access the damaged area, you will need to remove the baseboards. Use a hammer and a pry bar to gently remove the baseboards from the wall. Be careful not to damage the baseboards, as you will need to reuse them later.

3. Drill a Hole in the Center of the Bubble

Using a drill with a 1/8 inch bit, carefully drill a hole in the center of the bubble. This will allow you to inject adhesive into the damaged area.

4. Inject Adhesive

Using a syringe or adhesive injector, inject wood glue or epoxy adhesive into the hole. Be sure to fill the hole completely, but avoid overfilling it, as this can cause the adhesive to spill out.

5. Apply Weight on the Repaired Area

Place a weight or a heavy object on top of the repaired area. This will ensure that the adhesive is evenly distributed and will help to flatten the bubble.

6. Wait for the Adhesive to Dry

Allow the adhesive to dry completely, according to the manufacturer’s instructions. This may take a few hours or overnight, depending on the type of adhesive you used.

7. Replace the Baseboards

Once the adhesive is dry, remove the weight and use a utility knife to trim any excess adhesive that may have seeped out of the hole. Replace the baseboards by gently tapping them back into place with a hammer and a screwdriver.

Tips to Prevent Bubbles from Forming

Prevention is always better than cure. Here are some tips to prevent bubbles from forming in your laminate flooring:

  • Proper installation: Make sure that the flooring is installed properly, following the manufacturer’s instructions. This includes ensuring that the subfloor is level and that the flooring is acclimated to the environment before installation.
  • Moisture prevention: Keep your laminate flooring dry by wiping up spills immediately and using a dehumidifier in areas with high humidity.
  • Regular maintenance: Keep your flooring clean and well-maintained to prevent damage that can lead to bubbles.


Fixing a bubble in your laminate flooring may seem daunting, but with the right tools and materials, it can be done easily and quickly. By understanding the causes of bubbles and taking preventive measures, you can avoid this problem altogether. Remember to always follow the manufacturer’s instructions and take care when handling your flooring.
