Laminate Floor Repair: Everything You Need to Know


Laminate floors are a popular choice for homeowners due to their durability and affordability. However, like any other flooring material, they are prone to wear and tear over time. From scratches and chips to gaps between planks, laminate floors can often show signs of damage.

Luckily, many of these issues can be easily repaired without having to replace the entire floor. In this guide, we will walk you through the steps of repairing common laminate floor problems and restoring your floor to its former glory.

Materials Needed

Tools needed for laminate floor repair

Before starting any repair work, it is important to gather all the necessary materials. Here are some of the items you will need for most laminate floor repairs:

Laminate Floor Repair Kit:

These kits usually include a utility knife or a putty knife, colored putty or wax, and a blending brush. They come in a variety of colors to match your flooring.

Replacement Laminate Planks:

Keep some extra planks from the original installation for any severe damage that can't be repaired. Make sure any replacement board will perfectly match your existing flooring.

PVA Wood Glue:

This is a versatile adhesive that's perfect for fixing minor gaps or cracks. It's clear drying and easy to clean up.

Soft Cloth:

Used for cleaning the surface and for wiping off excess glue or putty.

Plastic Spacers:

These help maintain the expansion gap when replacing damaged laminate flooring.

Hammer and Tapping Block:

These tools are used to gently tap new planks into place without causing damage.

Circular Saw or Jigsaw:

These tools may be needed to cut replacement boards to the correct size.

Pry Bar:

This tool can help remove damaged planks without disturbing the surrounding ones.

Repairing Common Laminate Floor Problems

Scratches and Chips

Scratches and chips in laminate flooring

Scratches and chips on laminate floors can occur due to heavy furniture, pet claws, or sharp objects. Here's how you can fix them:

  1. Start by cleaning the damaged area with a soft cloth and a mild cleaner.
  2. Use the putty knife from your repair kit to fill the scratch or chip with colored putty or wax. Make sure to choose a color that matches your flooring.
  3. Use the blending brush to smooth out the excess putty and blend it with the surrounding area.
  4. Let the putty dry completely before walking on it.
  5. For deeper scratches, you may need to repeat the process or use a matching wood stain.

Gaps Between Planks

Gaps between planks can occur due to changes in humidity or improper installation. Here's how you can fix them:

  1. Identify the Gaps: Begin by examining the floor to identify all gaps. They may occur between a few planks or throughout the whole floor.
  2. Clean the Gaps: Use a vacuum cleaner or a soft brush to remove any dust or debris from the gaps. This ensures that the adhesive applied in the following steps bonds effectively.
  3. Apply PVA Wood Glue: Carefully apply a sufficient amount of PVA wood glue or any hardwood flooring glue into each gap. Be sure not to overfill as it might harden and cause a bulge between the planks.
  4. Close the Gaps: Use your plastic spacers to close the gaps. Place them along the wall nearest to the gap, then push the planks towards the spacers until the gap closes.
  5. Wipe Excess Glue and Let Dry: Wipe off any excess glue with a soft cloth and let it dry. Be sure not to walk on the floor until it’s completely dry, as this might reopen the gaps.

Warping or Buckling

Warping or buckling of laminate floors can occur due to excessive moisture. Here's how you can fix it:

  1. Identify and use a floor repair marker to mark the warped or buckled planks.
  2. Use a circular saw or jigsaw to cut out the damaged planks, making sure to leave a small expansion gap around the edges.
  3. Apply wood glue along the edges of the surrounding planks and gently tap the new plank into place using a hammer and tapping block.
  4. Wipe off any excess glue with a damp cloth and use plastic spacers to maintain the expansion gap while the glue dries.
  5. Once the glue is dry, remove the spacers and enjoy your newly repaired floor.


Peaking occurs when the laminate floor planks push up against each other, creating high points at the joints. This can be due to the floor not having enough space to expand and contract with changes in temperature or humidity, or due to improper installation. Here's how you can fix it:

  1. Identify the area where the floor is peaking.
  2. Remove the baseboard or molding around the affected area using a pry bar, taking care not to damage it.
  3. Use a circular saw or jigsaw to cut a small gap between the peaking planks to give the floor more room to expand and contract.
  4. Replace the baseboard or molding, allowing for an expansion gap between it and the laminate flooring.
  5. If the peaking continues, it may be necessary to consult a professional as it can indicate a serious installation problem.

Stains and Discoloration

Stains in laminate flooring

Stains or discoloration on laminate floors can occur due to spills, heavy foot traffic, or prolonged exposure to sunlight. Here's how you can fix them:

  1. Identify the stained or discolored area and clean it with a soft cloth and a mild cleaner.
  2. If the stain doesn't lift, try using a laminate floor cleaner or create a homemade solution of equal parts water, vinegar, and rubbing alcohol.
  3. Dampen a cloth with the cleaning solution and gently scrub the stained area.
  4. Dry the spot immediately with a clean, dry cloth.
  5. For stubborn stains, you may need to replace the discolored plank with a new one, following the process mentioned under 'Warping or Buckling'.
  6. To prevent discoloration in the future, consider using rugs or blinds to limit the floor's exposure to sunlight and heavy foot traffic. Also, clean spills immediately to prevent staining.

Laminate Floor Maintenance

Maintenance on laminate flooring

To prevent future damage to your laminate floors, here are some maintenance tips to keep in mind:

  • Avoid using steam cleaners or wet mops on laminate floors as excessive moisture can cause warping and damage.
  • Use felt pads under heavy furniture to prevent scratches and dents.
  • Sweep or vacuum regularly to remove dirt, dust, and debris that may scratch the surface of your laminate flooring.
  • Wipe up spills immediately to prevent staining and damage to the planks.
  • Use a mild cleaner specifically designed for laminate floors when mopping, and avoid using abrasive cleaners or tools.

Following these tips will help keep your laminate floors in great condition for years to come. Remember, if you encounter any major damages that cannot be fixed with these methods, it's best to consult a professional for repair or replacement.

Commonly Asked Questions

Q: Can I Use Regular Wood Putty to Repair Laminate Flooring?

A: While it’s possible to use regular wood putty to repair laminate flooring, it’s not typically recommended. Laminate flooring has a unique composition and finish that most wood putties can't match. For the best results, we recommend using a laminate floor repair kit that includes colored putty or wax specifically designed for laminate floors.

Q: How Often Should I Replace Laminate Flooring?

A: The frequency of replacing laminate flooring depends on its quality, the amount of foot traffic it receives, and how well it’s maintained. High-quality laminate floors that are properly cared for can last up to 25 years. If your floor shows signs of significant wear and tear, like deep scratches, warping, or multiple chipped areas, it might be time for a replacement.

Q: What Should I Avoid When Cleaning Laminate Floors?

A: When cleaning laminate floors, avoid using excessive water, as it can seep between the planks and cause warping or swelling. Additionally, avoid using abrasive cleaners or tools that could scratch the surface. Instead, use a soft cloth and a mild cleaner designed for laminate floors.

Q: Can I Repair Laminate Flooring Myself?

A: Absolutely! With the right tools and a bit of patience, most homeowners can repair common laminate flooring problems themselves. This guide provides detailed steps to help you through the process. However, if your floor is severely damaged or if you're not comfortable doing the repairs yourself, consider hiring a professional.

Q: Can I Use Any Type of Wood Glue for Repairing Laminate Floors?

A: We recommend using PVA wood glue for repairing laminate floors. This type of glue is clear drying, easy to clean up and works well for fixing minor gaps or cracks. It also bonds well with the fiberboard material in laminate flooring.

Q: Why Are There Gaps Between My Laminate Planks?

A: Gaps between laminate planks can occur due to changes in humidity, improper installation, or the natural expansion and contraction of the material. These gaps can be easily fixed with PVA wood glue and plastic spacers as explained in this guide.

Q: What Causes Warping or Buckling in Laminate Floors?

A: Warping or buckling in laminate floors is usually caused by excessive moisture. This could be due to a leak, high humidity levels, or wet mopping. The best way to deal with this is to replace the damaged planks as described in this guide, and address the source of the moisture to prevent future damage.

Q: What If I Don’t Have Replacement Planks?

A: If you don't have replacement planks from the original installation, you can try getting a match from the manufacturer or a flooring store. However, due to variations in dye lots, it might not be an exact match. If a match can't be found, you might have to consider replacing the entire floor or creating an intentional pattern with a contrasting plank to turn the damage into a design element.

Q: How Can I Prevent Damage to My Laminate Floors?

A: Regular cleaning and maintenance can help prevent many common laminate floor problems. Use furniture pads under heavy items, keep pet nails trimmed, and wipe up spills immediately. Additionally, control humidity levels in your home and avoid wet mopping to prevent warping or buckling.

Q: How Long Does It Take for the Repaired Area to Dry?

A: The drying time can vary depending on the type of repair and the specific products used. Generally, putty or wax from a repair kit dries within a few hours. However, wood glue used for fixing gaps or attaching new planks may take up to 24 hours to fully cure. Always follow the manufacturer's instructions on the product packaging for the best results.
