Identifying the Type of Scratches on a Hardwood Floor
Before undertaking any repairs, it is crucial to determine the exact nature of the scratches on your hardwood floor. This initial assessment will determine the appropriate repair method and prevent further damage.
| Scratch type | Features | Simple test | Difficulty level |
|---|---|---|---|
| Superficial | Only affects varnish | Disappears with a drop of water | Easy |
| Moderate | Goes through varnish, reaches wood | Visible even with water | Intermediate |
| Deep | Penetrates deep into the wood | Catch your nail as you pass by | Difficult |
To assess the depth of a scratch, gently apply a small drop of water to the mark. If the scratch disappears temporarily, it only affects the topcoat. If it remains visible, the scratch has penetrated deeper. Also run your fingernail perpendicular to the scratch: if your nail catches, the scratch is deep.
Surface scratches: immediate solutions
Superficial scratches account for the majority of damage observed and are fortunately the easiest to repair. These marks only affect the protective varnish layer.
Manufacturer Recommended Products
The first fundamental rule is to use only products recommended by your floor manufacturer. Each manufacturer develops solutions specifically formulated for their finishes, ensuring optimal compatibility and preserving your warranty.
- Colored wax crayons to cover light scratches
- Touch-up markers for fine scratches
- Finishing varnish to restore protection
Application techniques
For very minor scratches, a gentle buffing with a microfiber cloth may be sufficient. When using a wax crayon or marker, follow the manufacturer's instructions carefully. Apply the product in the direction of the grain, let it dry, then buff gently.
Repairing a Superficial Scratch (Step by Step)
- Clean the area with a soft cloth and a suitable product
- Dry the surface completely
- Apply a wax crayon or touch-up marker in the correct color
- Allow to dry according to the manufacturer's instructions
- Polish with a microfiber cloth
Homemade tip: the walnut technique
Some homeowners use a natural trick to camouflage small scratches: walnuts . Simply rub the edible part of a walnut directly onto the scratch. The natural oils in the walnuts penetrate the wood slightly, visually reducing the mark.
Please note : this method hides the scratch but does not actually repair it and works best on dark or oiled floors.

Deep Scratches: Advanced Techniques
Deep scratches that penetrate the wood require a more methodical approach. These repairs require patience and precision to achieve satisfactory results.
Essential preliminary assessment
Before attempting to repair a deep scratch, be sure to consult your floor's warranty documentation. Some techniques may void the manufacturer's warranty, even if performed correctly.
Recommended techniques
- Colored wood paste to fill in large scratches
- Localized sanding followed by a new application of varnish
- Blade replacement for irreparable damage
- Brush touch-up with matching stain and varnish
How to Repair a Deep Scratch (Step by Step)
- Clean the damaged area
- Fill the scratch with colored wood filler
- Allow to dry completely
- Lightly sand the repaired area to smooth it.
- Apply a matching stain or varnish to even out the finish
The process generally follows this sequence: thorough cleaning, application of the filler, complete drying, light sanding if necessary, then application of the finish.
One of the biggest challenges is achieving a perfect color match, as wood ages naturally. For personalized advice, contact our experts .
When to call a professional
Some situations require the expertise of a qualified professional. Call on a specialist for:
- Multiple extensive scratches covering a large area
- Damage extending through multiple floorboards
- Scratches accompanied by deformation of the wood
- Failure of previous repair attempts
- A floor under warranty requiring specific repairs
Home Repairs vs. Professional Repairs
| Type of repair | Homemade solutions (DIY) | Professional solutions |
|---|---|---|
| Light scratches | Wax crayon, touch-up marker, walnut technique | Uniform professional retouching |
| Deep scratches | Wood pulp, local sanding | Blade replacement, complete sandblasting |
| General finishing | Polish or varnish in a small area | Uniform finish across the entire surface |
| Expected visual result | Partial enhancement, variable color | Almost invisible and uniform finish |
Preventing future scratches
Prevention remains the most effective strategy for maintaining the appearance of your floor. Equip all your furniture with protective felt and replace it regularly. Never drag furniture directly across the floor.
Maintain a stable humidity level, which should be between 30% and 45% in winter, according to CAA-Quebec 's healthy home guidelines. Vacuum regularly and install quality entrance mats to better manage indoor air quality.

Common mistakes to avoid
- Use an abrasive product or a rough cloth which can damage the varnish
- Sanding a small scratch too aggressively and gouging the wood
- Applying a wood stain or filler without testing the color first
- Neglecting warranty documentation before any intervention
- Repairing a major scratch without the right equipment or preparation
Conclusion
Repairing scratches on a hardwood floor requires a methodical approach that begins with a thorough assessment of the damage. Following the manufacturer's recommendations remains essential to maintain your warranty and achieve lasting results.
Investing in prevention, combined with regular maintenance, is the most cost-effective strategy for maintaining the beauty of your hardwood floor.

After sanding and applying the varnish, allow approximately 4 days for drying before replacing the furniture.
