Parquet is one of the most durable floor coverings there is, but it can happen that it gets damaged as it ages or after an incident, causing scratches, holes, warping or squeaking. The solution is not necessarily to change the flooring, because in many cases the parquet can be repaired to restore a like-new appearance at a lower cost.
For the repair to be effective, the diagnosis must be correct, and you must choose the right method and the right products to avoid making the damage worse. Woodpartners helps you identify the different types of damage a parquet floor can suffer and how to repair it step by step.
How to repair a parquet floor in brief?
-
In the vast majority of cases, a damaged parquet floor can be repaired without having to change the covering, provided you use the right products depending on the type of floor (solid, engineered or laminate).
-
The most common damage to a parquet floor is scratches, holes, warping and squeaking.
-
Repairing a parquet floor follows 5 steps : make the right diagnosis, clean the area, fill the damage with the appropriate product, let it dry and sand, then apply the original finish.
-
Preventive maintenance is the best protection to avoid the vast majority of repairs.
Which parquet floors can be repaired ?
There are three types of parquet floors that can be repaired when they are damaged :
-
Solid parquet : this is the most premium and most robust parquet, made of a single thickness of wood, which offers the best repair capabilities because it can be sanded down to bare wood several times over its life and accepts all finishes (oil, wax, varnish/sealer).
-
Engineered parquet : also called floating parquet, it is made up of three layers, the top layer of which is a noble wood. The thicker the top layer, the more possible and long-lasting the repair of the floating parquet will be.
-
Laminate flooring : this is a composite material made of a wood fiberboard panel. There is no real wood on the surface, which makes sanding impossible, and repair options are limited to filling products (hot wax, acrylic filler) or replacing the plank.
What is the most common damage to a parquet floor ?
The most common damage to a parquet floor is :
-
Scratches that appear as linear marks caused by moving furniture without felt pads, repeated wear from stiletto heels, or pet claws. A distinction must be made between superficial scuffs, which only affect the finish layer, and deep scratches that cut into the wood itself.
-
Holes and impacts generally come from dropping a heavy object, a natural knot in the wood that comes loose over time, or in some cases from wood-boring insect activity. Depending on the size of the hole, the repair method will not be the same.
-
Warping, also called cupping, is almost always a reaction linked to a moisture problem. Since wood is a living material that continuously absorbs and releases moisture, when moisture is too high (water infiltration, excessive humidity, poorly installed underlay) the boards lift at the edges or bulge in the center.
-
Squeaking indicates mechanical friction somewhere: between two boards, between a board and its substrate, or between the parquet and its joist. This is a structural issue, not an aesthetic one, and it can often be repaired without having to completely dismantle the floor.
-
Varnish wear: over time the varnish/sealer film that protects a parquet floor ends up deteriorating. This shows up as dull areas, halos around high-traffic paths, or slight generalized micro-scratches on a sealed (vitrified) parquet floor.
What are the steps to repair a parquet floor ?
Repairing a parquet floor is done in 5 steps:
-
Make a diagnosis
-
Clean the damaged area,
-
Fill the damage with the appropriate product
-
Let it dry and sand off the excess
-
Apply the original finish.
Step 1 - Make the right diagnosis
This involves identifying the problem and the type of parquet: solid, engineered or laminate, because the repair will not be exactly the same. You will also need to identify the underlying cause of the problem and address it beforehand. For example, a warped parquet floor will swell again after repair if the moisture problem is not resolved.
Step 2: Clean the area to be treated
To start a repair properly, you need a clean, dry surface:
-
Carefully clean the area to be treated: remove dust, grease and residue with a slightly damp cloth and a neutral cleaner.
-
If you are working after water damage, make sure the wood is perfectly dry before applying anything, because residual moisture prevents fillers and finishes from adhering properly.
-
If the existing finish needs to be removed locally (peeling sealer, overly built-up waxed area), use a wax remover or appropriate stripper before starting to avoid touch-ups peeling off a few weeks after the work.
Step 3: Fill the damage
This step will depend on the type of damage the parquet has suffered : scratch, holes, warping. But whatever the damage, you must always use a product compatible with the existing finish (wood filler paste, putty or hot-melt wax). For example, if your parquet is oiled and you need to fill a hole with wood filler paste, you will not be able to apply a sealer/varnish over it because the varnish will not penetrate into the wood and will eventually peel off.
Step 4: Let dry and sand
Once the repair product has been applied, let it dry completely; you can expect between 30 minutes and 24 hours depending on the product used and the thickness applied. The putty or wood filler paste shrinks slightly as it dries; this is normal: that's why it is always applied with a slight excess thickness in the previous step.
Once dry, gently sand by hand with fine sandpaper (180 to 220 grit) to bring the repaired area exactly level with the surrounding floor, without gouging or leaving a residual bump. Note: on laminate flooring, sanding is impossible !
Step 5 : Apply the original finish
Once the hole is filled or the scratch is repaired, the original finish must be applied to the treated area so it blends into the rest of the floor.
-
On an oiled parquet floor, apply a maintenance oil in the same shade to the repaired area.
-
On a sealed (vitrified) parquet floor, light sanding with 120-grit followed by two thin coats of sealer helps restore a uniform appearance.
-
On a waxed parquet floor, applying a touch-up wax in the exact color of the floor is sufficient in most cases.
Our Woodpartners tip
Before applying your finish to the repaired area, always test it on a sample plank taken from under a baseboard or inside a closet. Wood reacts differently depending on its age and porosity: a sealer that is too glossy or a slightly off shade can make the repair more visible than the original damage.
How to repair a scratched parquet floor ?
To repair a scratched parquet floor, you must assess the depth of the scratch—whether it is light or deep.
Repairing a light scratch
For a superficial scuff on an oiled or waxed parquet floor, the simplest solution is to start by rubbing a freshly cracked walnut kernel on the scratched area. This tip works particularly well on dark woods such as walnut or stained oak. You can then apply damaged-parquet wax in the matching shade.
For a sealed (vitrified) parquet floor, a metallizing renovator or parquet polish can very quickly restore the floor’s shine.
Repairing deep scratches
When the scratch cuts into the wood itself, you must :
-
Carefully clean and degrease the area
-
Apply wood filler paste in the closest possible shade to the floor, using a plastic spatula. Above all, never use a metal spatula !
-
Apply the wood filler paste with a slight excess thickness to compensate for shrinkage while drying.
-
Once dry (allow between 30 minutes and a few hours depending on thickness), gently sand by hand and then apply the original finish, staying localized on the treated area.
On laminate flooring, there is no real wood on the surface, so it cannot be sanded. To repair a scratched laminate parquet floor, the recommended method is a parquet repair kit with hot-melt wax.
How to repair a parquet floor with holes ?
Repairing holes in a parquet floor mainly depends on the size of the hole :
-
If it is a small hole (up to 5 mm) : on a solid or engineered parquet floor, wood putty is the cleanest and most discreet solution. On a floor installed on joists, prefer a two-component water-based powder filler, which is more flexible and just as compatible with oil, wax and sealer.
-
If it is a large hole (more than 1 cm) : when the hole is significant, filler alone may sag during drying. The right technique is to fill the first half of the cavity with wood shavings of the same species and then finish with the filler of your choice on the upper part. On laminate flooring, the same logic applies with MDF or HDF shavings, then a two-component renovation paste or a wood-colored acrylic filler on the surface.
Good to know
If you notice many small round holes of 1 to 2 mm accompanied by fine white sawdust nearby, these marks are characteristic of wood-boring insects, whose presence requires curative treatment by injecting fungicide and insecticide.
How to repair a warped parquet floor ?
A warped parquet floor is almost always a reaction to excess moisture, so you must treat the cause of this excessive moisture before repairing.
Once the cause has been treated, you must :
-
Absorb standing water
-
Install a dehumidifier for several days
-
Do not dry the parquet floor abruptly, as you risk splitting and cracking the boards
-
During drying, place heavy weights on the areas that are warping.
In most cases, if drying is controlled and pressure is well maintained, the parquet regains its flatness without further intervention.
If the warping is linked to a lack of expansion rather than moisture, remove the baseboards and check that the gap between the boards and the walls is at least 8 to 10 mm.
Our Woodpartners tip
Do not prematurely replace warped boards before letting them dry completely, because replacement is only necessary when the boards are cracked, permanently deformed, or when mold has appeared under the wood.
How to repair a sealed (vitrified) parquet floor ?
A parquet floor damaged by abrasion or simply worn out over the years does not necessarily require a full sanding. Depending on the original finish — sealer/varnish, oil or wax — and the level of wear, there are more or less light restoration solutions. The finish determines not only the repair method, but also the final appearance.
A sealed (vitrified) parquet floor gradually deteriorates with natural wear because the varnish film wears out, but as long as the wood is not exposed, a metallizing renovator or parquet polish is enough to restore its shine.
When the sealer is truly degraded and there are peeling areas, if stains have penetrated the grain, or if there is bare wood in places, you need to :
-
Lightly sand the entire surface with 80-grit
-
Sand with 120-grit to remove remnants of the old varnish
-
Apply two thin coats of new sealer with sanding between coats.
This is a repair that takes about a day, but the result easily lasts 10 to 15 years with proper maintenance.
Good to know
To find out whether your parquet floor is sealed, oiled or waxed, pour a small drop of water on an inconspicuous area. If the drop beads without penetrating, the parquet is sealed. If it penetrates slowly leaving a slight halo, it is oiled or waxed. This information determines the choice of maintenance and repair products.
Repairing a parquet floor rather than replacing it is often the first choice for an authentic interior, a valued material and a more responsible approach.
