I’m your friendly neighborhood flooring contractor, and let me tell you, I’ve seen it all when it comes to floors. One of the most common issues I get calls about? Bubbling in fake wood flooring.

It’s frustrating, I know! You chose those beautiful laminate or vinyl planks for their affordability, style, and (hopefully) easy maintenance. But then, BAM! Bubbles pop up, ruining the smooth surface and your peace of mind.

Don’t worry, though. Addressing those unsightly bubbles can be surprisingly straightforward. I’m here to walk you through six proven fixes that can restore your floors to their former glory, saving you a ton of money on professional repairs. Let’s dive in!

Section 1: Understanding Fake Wood Flooring

So, what exactly is “fake wood flooring”? Well, it’s an umbrella term covering several types of flooring designed to mimic the look of real hardwood. The most common types are:

• Laminate Flooring: This is a multi-layer synthetic flooring product fused together using lamination. It simulates wood with a photographic applique layer under a clear protective layer.
• Vinyl Plank Flooring (LVP/WPC/SPC): Vinyl plank comes in various forms, including:
  • LVP (Luxury Vinyl Plank): Made of multiple layers of PVC vinyl.
  • WPC (Wood Plastic Composite): A waterproof core made from recycled wood pulp and plastic composites.
  • SPC (Stone Plastic Composite): An even more rigid and durable core made from limestone and stabilizers.

Benefits of Fake Wood Flooring

I often recommend fake wood flooring to clients for a few key reasons:

• Cost-Effectiveness: It’s significantly cheaper than real hardwood. According to HomeAdvisor, laminate flooring installation costs average around \$4 per square foot, while hardwood can easily reach \$8 or more.
• Ease of Installation: Many types, especially vinyl plank, are designed for DIY installation with click-lock systems.
• Maintenance: Generally easier to clean and maintain than hardwood, resisting scratches and stains.
• Aesthetic Appeal: Modern manufacturing techniques have made these floors look incredibly realistic.

The Dreaded Bubbling Issue

Despite all these advantages, bubbling is a common problem. It can be a minor annoyance or a major eyesore, and it’s important to address it quickly to prevent further damage. I’ve seen bubbles ranging from tiny little bumps to large, raised areas that feel spongy underfoot.

Section 2: Identifying the Causes of Bubbling

Okay, so you’ve got bubbles. Now what? The first step is to play detective and figure out why they’re there. Here are the most common culprits I’ve encountered:

• Moisture and Humidity: This is the BIGGEST offender. Fake wood flooring, especially laminate, is susceptible to moisture. Excessive humidity or water spills can cause the material to expand and buckle, leading to bubbles. I’ve seen this happen a lot in bathrooms and kitchens.

  • Statistic: The EPA recommends maintaining indoor humidity levels between 30-50% to prevent mold growth and other moisture-related issues.
  • Poor Installation: If the subfloor wasn’t properly prepared (level, clean, and dry) before installation, it can lead to uneven pressure and bubbling. Also, not leaving enough expansion gap around the perimeter of the room can cause issues as the floor expands and contracts with temperature changes.
  • Heavy Furniture/Appliances: Placing extremely heavy items directly on the floor without proper protection can compress the material and cause bubbling over time. I always advise using furniture pads!
  • Temperature Fluctuations: Extreme temperature changes can cause the flooring to expand and contract excessively, leading to stress and bubbling. Think about rooms with direct sunlight or uninsulated areas.
  • Chemical Reactions: Harsh cleaners or improper adhesives can react with the flooring material, causing it to break down and bubble. I always recommend using cleaners specifically designed for your type of flooring.

Assess Your Situation

Take a good look at your flooring. Where are the bubbles located? Are they near a water source? Did they appear after you moved heavy furniture? Answering these questions will help you pinpoint the cause and choose the right fix.

Section 3: Fix #1 – Allowing the Floor to Settle

Sometimes, the simplest solution is the best. In some cases, bubbling can occur due to minor shifts or pressure points in the flooring. Giving the floor time to acclimate and settle can sometimes resolve the issue.

Step-by-Step:

1. Identify the Affected Area: Locate the specific area where the bubbling is occurring.
2. Gently Lift the Flooring (If Possible): If the planks are easily accessible and not tightly locked, carefully lift the edge of the affected plank to relieve any pressure.
3. Reposition the Flooring: Gently reposition the plank, ensuring it’s aligned correctly with the surrounding flooring.
4. Wait and Observe: Give the flooring a few days to a week to settle. Avoid walking on the area as much as possible.

Signs of Success:

• The bubble gradually decreases in size.
• The flooring feels more stable and less spongy.
• No further bubbling occurs.

Important Note: This fix is most likely to work for very minor bubbling issues that appear shortly after installation or after moving furniture.

Section 4: Fix #2 – Moisture Management

As I mentioned earlier, moisture is a HUGE enemy of fake wood flooring. If you suspect moisture is the culprit, you need to tackle it head-on.

Practical Solutions:

• Dehumidifiers: Use a dehumidifier in damp areas like basements or bathrooms to lower humidity levels. I recommend models with a built-in hygrometer so you can monitor the humidity.
• Improve Ventilation: Ensure proper ventilation in bathrooms and kitchens by using exhaust fans during and after showering/cooking.
• Check for Leaks: Inspect plumbing under sinks, around toilets, and near appliances for any signs of leaks. Even small leaks can cause significant damage over time.
• Address Spills Immediately: Wipe up any spills immediately with a dry cloth. Don’t let liquids sit on the floor.

Using a Moisture Meter:

A moisture meter is a fantastic tool for assessing moisture levels in your flooring and subfloor.

1. Purchase a Moisture Meter: You can find them at most hardware stores. Look for one that’s suitable for wood and laminate flooring.
2. Calibrate the Meter: Follow the manufacturer’s instructions to calibrate the meter before use.
3. Test the Flooring: Place the meter on the affected area and note the reading.
4. Test the Subfloor: If possible, lift a plank and test the subfloor directly.
5. Interpret the Results: Readings above 12% generally indicate excessive moisture.

Target Moisture Levels: Aim for moisture levels below 12% in both the flooring and subfloor.

Section 5: Fix #3 – Re-gluing Loose Planks

Loose planks can create gaps that allow moisture to seep in, leading to bubbling. Re-gluing them can seal those gaps and prevent further damage.

Step-by-Step:

1. Identify Loose Planks: Locate any planks that feel loose or move when you step on them.
2. Carefully Lift the Plank: Use a putty knife or thin pry bar to gently lift the edge of the plank. Be careful not to damage the surrounding planks.
3. Clean the Area: Remove any debris or old adhesive from the subfloor and the back of the plank.
4. Apply Adhesive: Apply a thin, even layer of flooring adhesive to the subfloor.
5. Press the Plank Back Down: Carefully align the plank and press it firmly into place.
6. Weight the Plank: Place a heavy object (like a stack of books) on the plank to hold it in place while the adhesive dries.
7. Allow to Dry: Allow the adhesive to dry completely according to the manufacturer’s instructions (usually 24-48 hours).

Choosing the Right Glue:

• For Laminate: Use a moisture-resistant wood glue.
• For Vinyl: Use a vinyl flooring adhesive.

I’ve had great success with Loctite PL Premium Polyurethane Construction Adhesive for both laminate and vinyl repairs. Always read the label and choose an adhesive specifically designed for your type of flooring.

Section 6: Fix #4 – Using a Weight to Flatten Bubbling Areas

This is a simple but effective method for addressing minor bubbling issues. The idea is to apply consistent pressure to the affected area to flatten it out over time.

Step-by-Step:

1. Prepare the Area: Clean the bubbling area thoroughly.
2. Place a Protective Layer: Place a clean cloth or towel over the bubbling area to protect the flooring from scratches.
3. Apply Weight: Place a heavy, flat object on top of the cloth. Good options include:
   • A stack of books
   • A dumbbell or weight plate (wrapped in a towel)
   • A large, flat stone
4. Leave in Place: Leave the weight in place for several days to a week, or even longer for more stubborn bubbles.
5. Check Progress: Periodically check the area to see if the bubbling is decreasing.

Expected Outcomes:

• Minor bubbles may flatten completely.
• Larger bubbles may decrease in size.
• This method is most effective for relatively new bubbles.

Important Note: This method works best when combined with other fixes, such as moisture management.

Section 7: Fix #5 – Repairing Subfloor Issues

Sometimes, the problem isn’t the flooring itself, but the subfloor beneath it. An uneven or damaged subfloor can create pressure points that lead to bubbling.

Inspecting the Subfloor:

1. Remove a Plank: Carefully remove a plank in the affected area.
2. Check for Damage: Look for signs of moisture damage, such as rot, mold, or discoloration.
3. Check for Unevenness: Use a level to check for any dips or humps in the subfloor.

Repair Solutions:

• Leveling Uneven Areas: Use a self-leveling compound to fill in any dips or low spots in the subfloor. Follow the manufacturer’s instructions carefully.
• Replacing Damaged Sections: If the subfloor is severely damaged, you may need to replace the affected section. This involves cutting out the damaged area and installing a new piece of subfloor.
• Addressing Moisture Issues: If you find signs of moisture, address the source of the moisture and allow the subfloor to dry completely before installing new flooring.

Important Note: Subfloor repairs can be tricky. If you’re not comfortable doing it yourself, it’s best to hire a professional.

Section 8: Fix #6 – Replacing Damaged Planks

Sometimes, the damage is too severe to repair. If a plank is badly bubbled, cracked, or otherwise damaged, the best solution may be to replace it.

Step-by-Step:

1. Obtain a Replacement Plank: Ideally, you’ll have some spare planks left over from the original installation. If not, try to find a matching plank from the same manufacturer and style.
2. Remove the Damaged Plank: This can be tricky, especially with click-lock systems. Use a utility knife to carefully cut along the edges of the plank. Then, use a pry bar to gently lift the plank out.
3. Prepare the Area: Clean the subfloor beneath the removed plank.
4. Install the New Plank: Carefully align the new plank and click it into place. You may need to use a tapping block and hammer to ensure a tight fit.
5. Secure with Adhesive (If Necessary): If the plank doesn’t click in securely, you may need to use a small amount of flooring adhesive.

Matching the New Plank:

• Check Dye Lots: If possible, check the dye lot of the new plank to ensure it matches the existing flooring.
• Allow for Acclimation: Allow the new plank to acclimate to the room’s temperature and humidity for a few days before installing it.
