Repair Laminate Floors: A Complete DIY Guide

Laminate flooring is known for its durability, affordability, and sleek appearance—but even the toughest floors aren’t immune to wear and tear. Over time, everyday accidents like dropped items, water spills, and moving furniture can leave behind scratches, dents, or warped planks. Fortunately, many of these issues are easy to fix without calling in a professional. This guide will walk you through the most common laminate floor problems and how to repair them step by step.

What Is Laminate Flooring?

Laminate is a multi-layered synthetic flooring product designed to mimic the appearance of natural wood. It consists of a fiberboard core, a photographic image layer, and a clear protective top coat. While it's scratch-resistant and generally low-maintenance, damage can still occur—especially in high-traffic areas or homes with pets and kids.

Tools and Materials You’ll Need

Before starting any repair, gather these essentials:

  • Laminate floor repair kit (includes color-matching putty or filler)
  • Soft cloth or microfiber mop
  • Mild cleaning solution
  • Fine-grit sandpaper
  • Utility knife
  • Putty knife
  • Replacement planks (if needed)
  • Adhesive glue (for loose boards)
  • Rubber mallet and tapping block

Common Laminate Floor Issues—and How to Fix Them

1. Scratches

Minor scratches are the most common problem with laminate flooring, but they're also the easiest to repair.

Fix:

Clean the area thoroughly to remove dirt.

Apply the filler or wax from your repair kit, matching the color of your floor.

Smooth it out with a putty knife.

Buff the surface gently with a cloth to blend the repair.

Quick Tip: For very light surface scratches, rubbing a walnut over the area can help mask the mark naturally.

2. Dents

Heavy furniture or sharp impacts can leave dents or compressed areas.

Fix:

For shallow dents: Place a damp cloth over the dent and use a warm iron on top. The heat and moisture may help the laminate fibers expand.

For deeper dents: Use a wood filler or repair compound to fill the dent. Smooth with a putty knife and let it dry before lightly sanding and buffing.

3. Water Damage

Moisture is the enemy of laminate flooring. If water sits too long, it can cause boards to swell, warp, or even peel.

Fix:

Dry the area thoroughly with fans or a dehumidifier.

Assess the damage—if the plank is swollen, you’ll likely need to replace it.

Remove the damaged board using a utility knife.

Install the new plank, securing it in place and ensuring it matches the surrounding floor.

4. Gaps Between Planks

Changes in temperature and humidity can cause planks to separate slightly.

Fix:

Clean the gap to remove dust or debris.

Tap the planks gently back into place with a rubber mallet and tapping block.

Apply a small amount of glue along the seams to hold them together if the gap reopens regularly.

How to Prevent Future Damage

Prevention is the best repair. Keep your laminate floor in great shape with these habits:

  • Use felt pads under furniture legs.
  • Avoid dragging heavy items across the floor.
  • Mop with a slightly damp (not wet) mop—never let water pool on the surface.
  • Keep pet nails trimmed to avoid deep scratches.
  • Maintain consistent indoor humidity levels to minimize expansion and contraction.

Frequently Asked Questions
