Quick answer: Clean the scratch and identify its depth first. For light, superficial scratches that only affect the finish, buff in a matching wood wax stick or blending pencil. For deeper scratches that penetrate the wood, fill with wood filler, sand smooth, and refinish to match. Widespread scratching across the floor usually calls for professional sanding and refinishing rather than spot repairs.
Scratches are almost inevitable on a wood floor that actually gets used, whether from pet claws, dragged furniture, or grit tracked in on shoes. The good news is that most scratches are fixable at home once you understand what type you are dealing with and which finish your floor has.
Identify Your Floor’s Finish First
Before attempting any repair, work out what kind of finish is on your floor, since this determines which products will actually work. Check whether the floor has an oil-based or water-based finish, a wax coating, or is varnished, stained, or has a factory-applied aluminium oxide finish common on some pre-finished hardwood. Using the wrong repair product on the wrong finish type can leave a visible mismatch rather than blending in.
Understanding Scratch Severity
Superficial Scratches
These only affect the protective coating or finish on top of the wood, without reaching the wood itself. They are usually only noticeable in certain light or from specific angles.
Minor Scratches
These penetrate the protective finish and reach the wood underneath, but do not go deep into the timber itself.
Deep Scratches or Gouges
These cut into the wood significantly and are more visible, often needing filler rather than a simple surface treatment.
Fixing Superficial Scratches
- Clean the scratch and surrounding area thoroughly with a soft cloth and floor cleaner to remove dust and grit.
- Wipe away any excess cleaner with a second cloth and water, then let the area dry completely.
- Apply a wood wax stick matched to your floor’s colour, or a small amount of your floor’s specific protective coating, directly into the scratch.
- Once dry, buff gently with a clean, soft cloth to blend the repair into the surrounding finish.
A natural alternative for very light scratches is rubbing a walnut over the mark. The natural oils and dyes released can help disguise light surface scratches, particularly on medium to dark wood tones.
Fixing Minor Scratches
- Clean the area thoroughly as above, making sure the inside of the scratch itself is free of dirt.
- For small, faint scratches, a wood touch-up marker or blending pencil matched to your floor’s tone can disguise the mark effectively.
- For slightly more visible minor scratches, rub a small amount of matching wood stain into the scratch with a cotton bud, then wipe away the excess before it dries fully.
- Finish with a light buff and, if needed, a thin layer of matching protective coating over the top.
Fixing Deep Scratches and Gouges
- Clean the scratch thoroughly, making sure no debris remains inside the gouge.
- Apply wood filler or putty matched to your floor’s colour using a putty knife, pressing it firmly into the scratch so there are no air gaps.
- Level the filler with the surrounding surface using the edge of the putty knife.
- Once fully dry, sand gently with fine-grit sandpaper until the area is smooth and level with the rest of the floor.
- Apply a matching finish or stain over the repaired area to blend it with the surrounding wood.
When to Consider Full Resanding
If your floor has widespread, noticeable scratching across multiple boards rather than a single mark, spot repairs will only mask individual scratches rather than restoring an even overall look. In this case, sanding and refinishing the whole floor gives a far more consistent result. Hardwood floors can typically be sanded and refinished four to six times over their lifetime, depending on the thickness of the boards and the skill of the person doing the work.
A Note on Engineered Wood
Engineered wood floors have a thinner real wood layer on top of a plywood or composite base, and this affects whether resanding is possible. Sanding typically removes at least 1mm of surface material, so an engineered floor needs a real wood layer thicker than this to allow for a full resand. Bamboo flooring cannot be sanded and refinished in the same way as solid wood at all, so scratch repair on bamboo relies entirely on the surface-level methods above.
Preventing Future Scratches
- Fit felt pads to the base of furniture legs, and lift rather than drag heavy items across the floor.
- Trim pets’ nails regularly if scratching is a recurring issue.
- Use a doormat at entrances to reduce grit being tracked in on shoes, which is one of the most common causes of fine surface scratching over time.
- Clean with a soft-bristled broom or a vacuum without a beater bar, since stiff bristles and rotating brush heads can scratch hardwood even during routine cleaning.

Frequently Asked Questions
Can you fix a deep scratch on a wood floor yourself?
Yes, in most cases. Clean the scratch, fill it with a matching wood filler, sand it smooth once dry, and finish with a matching stain or coating to blend it in.
How many times can a hardwood floor be sanded and refinished?
Typically four to six times over the floor’s lifetime, depending on the thickness of the boards and how much material is removed with each sanding.
Does walnut really remove scratches from wood floors?
Rubbing a walnut over a light, superficial scratch can help disguise it by releasing natural oils and dyes into the mark, though it works best on lighter, cosmetic scratches rather than deeper damage.
Can engineered wood floors be sanded like solid wood?
Only if the real wood surface layer is thick enough, generally more than 1mm, since sanding removes a similar amount of material regardless of floor type. Thinner engineered layers cannot withstand a full resand.
Final Thoughts
Fixing a scratched wood floor comes down to correctly identifying the finish, judging how deep the damage goes, and matching your repair method accordingly. Superficial marks need little more than a wax stick and a buff, while deeper gouges call for filler and sanding, and widespread scratching is usually best resolved with a full professional resand.
