A small chip or scratch in your laminate or vinyl flooring can be an eyesore, but the good news is that most minor damage is well within a confident DIYer's ability to fix. With the right repair kit and a steady hand, you can have your floor looking near-perfect again in under an hour — no tradesperson required for small jobs.
Understanding the Difference: Laminate vs Vinyl
Before you grab a repair kit, it helps to know what you're working with, as the repair approach differs slightly.
- Laminate flooring has a photographic layer beneath a hard wear layer, bonded to an HDF (high-density fibreboard) core. Chips and deep scratches can expose the core, which is vulnerable to moisture.
- Luxury vinyl plank (LVP) or vinyl composite tile (VCT) is made from PVC layers and is more flexible and waterproof. Scratches tend to be shallower and the material is more forgiving to repair.
If you're unsure which you have, check the edge of a plank in a doorway or under a skirting board — laminate will show a wood-fibre core, while vinyl will look solid and plastic-like throughout.
What You'll Need
For most small repairs you'll need:
- Laminate/vinyl floor repair kit (available from Bunnings or Mitre 10) — these typically include coloured wax or resin sticks, a spatula, and sometimes a grain tool
- Soft cloths and a mild floor cleaner
- Fine-grit sandpaper (for laminate only, used very carefully)
- A hairdryer or heat gun on low (for wax-based kits)
- Matching colour wax crayons or putty sticks
| Damage Type | Best Fix | Difficulty |
|---|---|---|
| Surface scratch (laminate) | Repair crayon or wax stick | Easy |
| Surface scratch (vinyl) | Vinyl repair kit or clear floor polish | Easy |
| Small chip (laminate) | Resin filler or wax repair kit | Moderate |
| Small chip (vinyl) | Vinyl filler or repair compound | Moderate |
| Large gouge or crack | Replace plank | Harder — consider a pro |
Step-by-Step: Fixing a Scratch in Laminate
- Clean the area thoroughly with a damp cloth and allow it to dry completely.
- Choose the right colour wax stick or crayon from your repair kit. Many kits include multiple shades — blend them if needed to match your floor's tone.
- Rub the wax stick firmly along the scratch, filling it in. Apply slightly more than needed.
- Smooth it off with a plastic spatula or an old credit card, working at a 45-degree angle to avoid pulling the wax back out.
- Buff gently with a soft cloth in a circular motion until the repair blends with the surrounding floor.
- For deeper scratches, a second application after the first has set can improve the result.
Step-by-Step: Fixing a Chip in Laminate
Chips that expose the HDF core need a slightly more robust approach:
- Clean and dry the damaged area.
- Use a resin-based filler (often included in laminate repair kits) rather than a soft wax — this gives a harder, more durable finish.
- Apply the filler in thin layers, allowing each to dry before adding the next, until the chip is slightly overfilled.
- Once fully dry, carefully sand flush with very fine-grit sandpaper, then use a matching wax crayon to restore the colour and grain appearance.
- Seal with a small amount of floor finish or clear lacquer to protect the repair from moisture — this is especially important as BRANZ notes that moisture ingress into laminate cores is a leading cause of floor failure.
Step-by-Step: Fixing Scratches and Chips in Vinyl
Vinyl is generally more forgiving:
- Clean the area and let it dry.
- For light scratches, rub a matching colour repair crayon over the scratch and buff smooth.
- For chips or gouges, use a vinyl floor repair compound — apply with a spatula, smooth flat, and allow to cure as per the product instructions.
- Some kits include a grain texture plate you press into the wet compound to mimic the floor's surface texture before it sets — this gives a much more natural result.
- Once cured, apply a thin coat of clear vinyl floor sealer to blend the sheen.
Colour Matching Tips
Colour matching is the trickiest part of any floor repair. A few tips:
- Take a photo of your floor in natural light to a flooring or hardware store when buying your kit.
- If you kept any offcuts from installation, bring one along — this is the best reference.
- Mix two wax colours together on a piece of cardboard to test the blend before applying to the floor.
- Err on the side of slightly lighter rather than darker — you can always add more.
Preventing Future Damage
- Place felt pads under furniture legs.
- Use entrance mats at doorways to trap grit (a common cause of scratching).
- Avoid dragging heavy objects across the floor.
- Keep pet nails trimmed.
- Follow the manufacturer's cleaning guidelines — harsh cleaners can dull the wear layer and make scratches more visible.
When to Call a Professional
If the damage is extensive — covering a large area, affecting multiple planks, or if the floor is lifting, buckling, or showing signs of moisture damage underneath — a DIY repair won't cut it. A full plank replacement is often the better solution, and a qualified flooring installer can do this efficiently, especially with click-lock systems.

Note: Floor repairs don't involve any restricted electrical, plumbing, or gas work, so there are no licensing requirements for this type of DIY job. However, if your floor damage is related to a plumbing leak, have a licensed plumber from the Plumbers Gasfitters & Drainlayers Board investigate the source before repairing the floor.
