Fixing Bubble in Laminate Flooring: A Step-by-Step Guide

Bubble in Laminate Flooring

Bubble in laminate flooring occurs due to insufficient room for boards to expand, leading to raised edges that may resemble bubbling. This issue is exacerbated by moisture entering exposed joints.

It can be fixed by bursting minor bubbles with a damp cloth and applying wood glue. In cases of severe water damage, damaged boards must be replaced. Proper installation with adequate spacing is crucial to prevent future bubbling in laminate flooring.

Laminate flooring offers a cost-effective and aesthetically pleasing alternative to hardwood floors. However, issues like bubbling can arise if not installed correctly or maintained appropriately. Understanding the root cause of bubble formation and knowing how to fix it is essential for preserving the lifespan and appearance of laminate flooring. Whether you’re a homeowner dealing with bubbling floors or a DIY enthusiast looking for solutions, this guide provides practical tips and insights to address and prevent bubble issues in laminate flooring effectively.

Identifying The Bubble

Laminate flooring bubbles are a common issue that can detract from the beauty of your floors. It’s essential to identify these bubbles early to prevent further damage.

Visual Inspection

During a visual inspection of your laminate flooring, look out for irregularities such as raised edges or blister-like formations. Bubbles are usually visible and can vary in size.

Tapping Test

Perform a tapping test by gently tapping the area with a blunt object. A hollow sound indicates the presence of a bubble beneath the surface.

Preparation For Repair

Before fixing bubble issues in laminate flooring, proper preparation is essential to ensure a successful repair. Adequate preparation helps in addressing the problem effectively.

Gathering Materials

Ensure you have the necessary materials ready for the repair: wood glue, a damp cloth, sharp knife, replacement laminate flooring boards, measuring tape, and a clean cloth for wiping.

Clearing The Area

Prior to repair, clear the area around the bubbled laminate flooring. Remove any furniture or obstacles to provide easy access to the damaged area.

Fixing The Bubble

Fixing a bubble in laminate flooring is an essential task to maintain the aesthetic appeal and functionality of your floors. While bubbles can be unsightly, the good news is that they can be repaired effectively. Here are the steps for fixing the bubble in laminate flooring:

Creating A Slit

First, create a small slit on the bubbled area using a sharp utility knife. This allows the trapped air to escape and prepares the area for the application of wood glue.

Applying Wood Glue

After creating the slit, carefully squeeze wood glue into the opened space. Ensure that the glue is evenly distributed to effectively secure the affected area back to the subfloor.

Weight Placement

Once the slit is made and wood glue is applied, place a heavy object, such as a stack of books or a weight, on top of the repaired area. This pressure will help the laminate flooring bond firmly to the subfloor and eliminate any remaining air pockets.

Prevention And Maintenance

Bubble in laminate flooring can be a frustrating issue, but with proper prevention and maintenance, you can keep your floors looking smooth and pristine. In this section, we’ll explore some essential tips to ensure your laminate flooring stays bubble-free for years to come.

Ensuring Proper Expansion Space

One common cause of bubbles in laminate flooring is the lack of proper expansion space. When laminate flooring is installed, it needs room to expand and contract with changes in temperature and humidity. Without sufficient space, the boards can strain against each other, causing raised edges that mimic bubbling. To prevent this issue:

  • Measure the room carefully before installation and leave a 1/4-inch expansion gap around the perimeter.
  • Use spacers to maintain the correct gap while installing the flooring.
  • Ensure the expansion gap is not blocked by baseboards or other obstacles.

Avoiding Water Damage

Water damage is another common culprit behind laminate flooring bubbles. When water seeps into the joints or gets trapped beneath the laminate, it can cause the boards to swell and bubble. To prevent water damage:

  1. Wipe up spills immediately using a dry cloth.
  2. Avoid wet mopping the floor and instead use a damp mop or specialized laminate floor cleaner.
  3. Place mats or rugs near entrances and high-moisture areas to catch dirt and moisture.
  4. Use a moisture barrier underlayment during installation to protect against subfloor moisture.

Remember, prevention is key when it comes to bubble in laminate flooring. By ensuring proper expansion space and taking steps to avoid water damage, you can maintain the beauty and longevity of your laminate floors for years to come.
