Restoring a Damaged Oak Parquet Floor with an Oil-Wax Impregnation

Estimated reading time: 9 minutes

An oak parquet floor with an oil-wax impregnation can lose colour, protection, and visual uniformity over time. This often happens because of incorrect maintenance or unsuitable products. However, if the wood is still structurally sound, replacement is not always necessary. With a professional restoration process, the surface can regain balance, beauty, and long-term protection.

In this article, we look at the restoration of a damaged oak parquet floor carried out by the Luigi Bernardi Company from Prato, Italy. Through cleaning, fibre preparation, oil-wax impregnation, and final protection, the floor recovered its original appearance and enhanced the natural qualities of the wood.

The problem: an oak parquet floor damaged over time

The oak parquet floor showed clear signs of deterioration. Poor maintenance and previous renovation work had damaged the surface. As a result, the wood looked whitened, greyed, depleted, and no longer protected. It was also more exposed to dirt absorption and everyday wear.

When an oil-wax impregnated parquet floor gradually loses its protective treatment, the wood becomes more vulnerable. Moisture, dirt, and foot traffic can affect it more easily. Therefore, before applying a new protection, the surface must be correctly restored. This means removing surface changes and preparing the wood for a new treatment cycle.

For this project, the craftsman followed a specific restoration cycle for oil-treated wooden floors. Each step was carried out with care and precision. As a result, the parquet recovered its natural appearance and gained renewed protection over time.

The stages of the parquet restoration

The floor was restored through a sequence of carefully planned steps. Each stage respected the characteristics of the oil-wax impregnated oak. Moreover, every step prepared the surface for the next one and helped create an even, durable, and natural-looking result.

1. Cleaning the parquet with SMACCHIO LEGNO

The first stage involved a deep cleaning of the parquet with SMACCHIO LEGNO. This product is designed to remove accumulated dirt and the grey patina that altered the appearance of the oak.

To achieve this result, the craftsman:

• applied the product evenly across the entire parquet surface;
• kept the wood constantly wet for about 20-30 minutes, reapplying the product where needed;
• worked the surface with a medium-hard pad to remove the grey surface layer;
• rinsed the parquet thoroughly to remove all product residues;
• left the wood to dry completely for at least 24 hours.

Before applying any new protection, it is essential to wait for favourable environmental conditions. This allows the wood to dry properly and prevents problems during the next treatment stages.

SMACCHIO LEGNO is not a paint stripper or a wax remover. It does not remove layers of varnish, impregnating treatments, oils, or waxes. Preliminary tests should always be carried out on a small area.

This stage is essential because it removes surface greying without removing the residual treatment already present in the wood. It also prepares the parquet for the following restoration steps.

2. Recompacting the wood fibres

Once the cleaning stage was complete and the floor was fully dry, the craftsman carried out light sanding with 100/120-grit abrasive paper.

This step was carried out to:

• recompact the oak fibres, which had slightly lifted during washing;
• even out the surface without changing the parquet finish;
• remove small irregularities created during the cleaning stage;
• prepare the wood to absorb the next impregnating treatment evenly.

This was not a full sanding process. Instead, it created the ideal conditions for correct absorption of the impregnating treatment and helped achieve an even final result.

3. Restoring the impregnation with RIPARA PARQUET

After preparing the surface, the craftsman restored the protective treatment of the parquet with RIPARA PARQUET. This oil-wax impregnating product is designed to protect indoor wooden floors.

The product can be used undiluted or diluted with AGRUMOIL or DILUOIL. Dilution can help the product penetrate dense and oily woods, such as teak and iroko.

In this restoration project, the treatment was applied in two coats. This helped nourish the oak in depth and restore even, long-lasting protection. This stage requires care, because the product must penetrate the wood evenly without leaving surface build-up.

For the first coat, the craftsman carried out these steps:

• applied RIPARA PARQUET with a wax spreader fleece, wetting the whole surface evenly;
• followed the natural absorption of the wood during application;
• waited about 10-15 minutes;
• removed the excess product with a cloth or soft disc;
• left the floor to dry for at least 12-24 hours, until the surface was dry and no longer oily to the touch.

Once drying was complete, the craftsman applied the second coat of RIPARA PARQUET. He repeated the same procedure to complete the impregnation cycle.

4. Applying the BIOTOP protective finish

The following day, once the surface was perfectly dry, the craftsman completed the restoration cycle with one coat of BIOTOP. This protective finish is designed for oil-impregnated wooden floors. It protects the impregnation from stains, dirt, and foot traffic wear, while preserving the natural look of the parquet.

For correct application of the finish:

• shake BIOTOP well before use;
• apply a thin, even coat on the floor with a wax spreader fleece, sponge, or soft cloth;
• spread the finish without leaving excess product or standing residues on the surface;
• allow the treatment to dry for about 1-2 hours;
• polish the surface with a nylon brush, tampico brush, or soft synthetic fibre discs.

In general, one coat of BIOTOP is enough. However, a second coat may be needed on wood with a textured finish, such as brushed, aged, or sandblasted surfaces.

In summer, or in very ventilated rooms with temperatures above 25°C, BIOTOP can dry too quickly. In these cases, it is advisable to dilute BIOTOP with 30% water and apply two light coats.

It is important not to leave the finish standing on tannin-rich woods, such as oak, chestnut, and larch. During hot weather, or in very ventilated rooms, it can also be useful to dilute BIOTOP 3:1 in water to make application easier.

After application, the tools should be rinsed with water before the product dries.

Final result: restored and protected oak parquet

At the end of the restoration, the oak parquet regained a warmer, more even, and more natural appearance. The surface, which had become faded, greyed, and deprived of nourishment, was thoroughly cleaned, re-impregnated, and protected with a finish specifically developed for oil-treated wooden floors.

This restoration improved both the appearance and the protection of the wood. The floor is now more attractive, less vulnerable to dirt, and easier to preserve over time with proper routine maintenance.

How to maintain an oil-wax impregnated parquet floor

After a professional restoration, regular maintenance is essential to preserve both the appearance and the protective treatment of the parquet. An oil-wax impregnated parquet floor should always be cleaned with dedicated wood-care products and maintained periodically using compatible maintenance treatments.

• For routine cleaning, use PULIBRILL®, a cleaner specifically formulated for wooden floors and parquet.
• For periodic maintenance, use BIOCARE, a maintenance treatment designed for oil-finished wooden floors.

Using the right cleaning products helps preserve the protective treatment and keeps the wood stable, clean, and protected for longer. By contrast, aggressive or unsuitable cleaners can wear away the protection prematurely and make another restoration necessary.

Conclusion: professional craftsmanship makes all the difference

Restoring a damaged oil-wax impregnated oak parquet floor is not simply a matter of choosing the right products. It also requires the ability to assess the condition of the wood correctly and select the most suitable restoration system.

In this project, Luigi Bernardi Company carried out a carefully planned restoration that respected the natural characteristics of the oak while restoring long-lasting protection without altering its authentic appearance.

When restoration is entrusted to a skilled flooring professional, the parquet is not merely cleaned. It regains its natural beauty, protective performance, and long-term durability.
