How to Repair Laminate Floors: A Complete DIY Guide

Laminate flooring is a favorite among homeowners for good reason—it's stylish, affordable, and easy to maintain. But even the most durable floors aren’t immune to everyday wear and tear. Scratches, dents, gaps, or water damage can pop up over time. The good news? Most of these issues are fixable without calling in a pro. Here’s your step-by-step guide to restoring your laminate floor like new.

What Is Laminate Flooring?

Laminate flooring is made of several layers—a high-density core topped with a photographic layer that mimics wood or stone, finished with a clear protective coating. It’s budget-friendly and surprisingly resilient, but not indestructible. Over time, you might run into:

  • Scratches from moving furniture or pet claws
  • Dents from dropped items or heavy furniture
  • Water damage from spills or leaks
  • Gaps between planks due to humidity or temperature changes

Tools & Materials You’ll Need

Before you start any repair, gather the right supplies. Here’s a basic list:

  • Laminate floor repair kit (color-matched wax, putty, or markers)
  • Soft cloth or microfiber mop
  • Laminate-safe cleaner
  • Putty knife
  • Fine-grit sandpaper
  • Utility knife
  • Replacement planks (if needed)
  • Wood glue or laminate adhesive
  • Rubber mallet and tapping block (for gaps)

1. How to Repair Scratches

Minor scratches are common but easy to fix.

Steps:

  • Clean the area: Wipe with a soft cloth and laminate-safe cleaner.
  • Apply filler or crayon: Use a repair kit that matches your floor’s color.
  • Blend it in: Use a putty knife to smooth it out and a clean cloth to buff.

💡 Tip: For very light scratches, rubbing a walnut or applying a small amount of coconut oil can help mask the blemish.

2. Fixing Dents in Laminate

Shallow dents caused by heavy objects can often be lifted or filled.

Steps:

  • Apply heat and moisture: Place a damp cloth over the dent and gently press a warm iron over it. The moisture and heat may expand the compressed laminate.
  • Use wood putty: For deeper dents, apply filler and smooth it with a putty knife.
  • Finish it off: Once dry, lightly sand and apply color if needed.

3. Repairing Water Damage

Warped or bubbled planks are often caused by water.

Steps:

  • Assess the area: Determine if the damage is isolated.
  • Dry the spot: Use a fan or dehumidifier to remove moisture.
  • Replace planks (if necessary): Carefully cut out the damaged plank with a utility knife. Snap or glue a new plank into place.

💡 Note: If the moisture reached the subfloor, allow it to dry completely before installing new boards.

4. Closing Gaps Between Planks

Seasonal changes can cause laminate planks to separate.

Steps:

  • Clean the gaps: Vacuum or wipe out any debris.
  • Tap them back: Use a tapping block and rubber mallet to gently shift planks back together.
  • Secure if needed: Apply a small amount of wood glue along the seam (only if necessary).

💡 Tip: Ensure expansion gaps were left during the original install. If not, trimming the floor edges can relieve pressure.

Preventing Future Damage

Keep your laminate floors looking fresh with a few smart habits:

  • Use furniture pads under legs
  • Clean up spills immediately
  • Avoid excess water when mopping
  • Keep humidity levels consistent
  • Sweep or vacuum regularly to avoid scratches from debris
