Not every mark on a timber floor is a sanding job. Gaps, scratches and dull patches are three of the most common complaints we hear from timber floor owners, and in almost every case, the right product can fix the problem without a single pass of a floor sander.
The trick is matching the fix to the problem. A gap filler, a scratch repair product and a dulling treatment are three very different things, and using the wrong one can leave you no better off. In this guide, we'll walk through each scenario separately, so you can find your issue and go straight to the fix.
Fixing Gaps Between Floorboards
Gaps between boards are one of the most common timber floor complaints, and they're rarely a sign of a problem with the floor itself. Timber is a natural material that moves with the seasons, shrinking slightly as the air dries out over winter and swelling again as humidity rises. Small gaps opening up over the colder months is normal, and in most cases, they can be filled rather than left to widen over time.
For one-off gaps, Berger-Seidle Aqua-Seal FlexFill is the easiest fix. Tape either side of the board, fill the gap straight from the tube, level it off with a putty knife, then leave it to dry. It's elastic and colour-matched, so it moves with the timber and blends straight into the surrounding boards.
If gaps run across the whole floor rather than a few spots, that's usually tackled during a full sand and refinish using Pafuki or Pak Stop, which are designed to be sanded flush and coated over.
You'll find the full range, including sizes and colours to match different timbers, in our Timber Gap Fillers collection.
Fixing Scratches on Oiled or Waxed Floors
Oiled and waxed floors handle scratches differently to floors finished with a hard lacquer or polyurethane. Because there's no hard film sitting on top, a scratch on an oiled floor is usually a surface-level mark in the finish rather than damage to a coating, which makes it a more straightforward spot repair.
To fix a scratch on an oiled or waxed floor:
- Clean the affected area with WOCA Intensive Wood Cleaner and allow it to dry completely
- Apply WOCA Maintenance Gel to a scourer sponge or hand scrubber, working it into the scratch in a thin, even coat
- Wipe down immediately with a clean, dry polishing cloth to remove any excess gel
- Leave the area to cure before walking on it or exposing it to moisture, following the timeframes on the product
Because Maintenance Gel is designed specifically to remedy minor scratches and blemishes on oiled surfaces, it blends the repair into the surrounding finish rather than leaving an obvious patch. If your floor is finished with a hard wax oil rather than a straight oil, the same underlying principle applies. Our guide on Hard Wax Oil vs Polyurethane Coatings explains why these penetrating finishes are generally easier to spot-repair than a hard film coating.
Restoring Dull, Faded or Worn Patches
A dull patch, especially in high-traffic areas, doesn't automatically mean your floor needs a full refinish. In most cases, it simply means the surface treatment in that spot has worn thinner than the rest of the floor, and the right fix depends on what your floor is finished with.
Oiled and waxed floors
On an oiled or waxed floor, a dull patch usually means the oil has worn down with foot traffic and needs replenishing, not that the floor needs sanding. WOCA Maintenance Oil is designed to revitalise worn oiled timber, restoring the glow and grain in patches that have lost their shine.
If you'd rather stay ahead of dull patches before they appear, the WOCA Floor Care Bundle pairs a weekly natural soap clean with a quarterly oil-refreshing treatment, which keeps the whole floor topped up before any one area starts to look tired.
Lacquered, vinyl and laminate floors
On lacquer, vinyl or laminate, dullness is usually a haze sitting on top of the finish rather than a worn-through coating. Berger-Seidle Brilliance Everclear is a maintenance treatment built to restore shine to sealed wood, vinyl and laminate floors between full recoats. The Berger-Seidle Floor Care Bundle pairs Everclear with a regular neutral cleaner in one kit, so you've got everyday cleaning and periodic shine restoration covered together.
If you've tried a maintenance product and a patch is still visibly duller, rougher or more worn than the rest of the floor, that's usually a sign the finish itself has broken down in that spot rather than just picked up surface grime. At that point, a light screen and recoat of the affected area is generally the next step, and it's worth getting in touch with our team to talk through the best option for your specific floor.

FAQs
Do I need to sand before using a timber floor filler?
No sanding is needed beforehand for spot filling. Clean the gap of dust and debris, apply the filler, level out with a putty knife and let it cure.
Can I use gap filler on a floor I plan to oil, versus one I plan to varnish?
Yes, timber floor fillers are suitable for use under both oil and varnish finishes. The main thing to check is the drying and curing time on your chosen filler, since it needs to be fully cured before you sand it back and apply your finish.
Will WOCA Maintenance Gel work on lacquered floors?
No. Maintenance Gel is formulated specifically for oiled and waxed floors. For scratches or dullness on lacquered, vinyl or laminate floors, a product like Berger-Seidle Brilliance Everclear is the better fit.
How do I know if my floor needs a full sand, or just a repair?
If the damage is limited to a scratch, a gap, or a patch of dulling that responds to cleaning and a maintenance product, a targeted repair is usually all you need. A full sand back is generally only necessary when the finish has failed extensively across the floor, boards are cupping or warping, or there's damage that goes beyond the surface finish and into the timber itself.
