Can I change the color of my wood flooring?

Yes, with Osmo Polyx®-Oil Tints, Professional Color-Oil, Oil-Stain and Wood Wax Finish. Apply the finish with a stiff floor brush, roller or a paintbrush. Ensure that the coat is applied thinly. Allow the floor to dry overnight, make sure to ventilate well while drying, and then apply one thin coat of Polyx®-Oil to the finish.

How do I prepare the surface of my wooden floor?

The surface should be sanded along the wood grain, ending with grit P 120-150 sandpaper. Care should be taken when removing any scratches.

What do I do if part of my floor is damaged?

Unlike many traditional lacquers, damaged areas on floors treated with Osmo products can be sanded and recoated with the same products without leaving any visible transitions.

Do I need to sand between the coats?

You should always assess the surface before applying the second coat, as sanding between coats may be necessary.

Is there anything I should pay attention to when treating wood flooring?

Due to the density and the wood extractive content, for example resins and oils, of some hardwoods, such as Jatoba and Merbau, they can absorb little material. Therefore, we recommend treating such woods with Wood Wax Finish Clear Extra Thin or Osmo Polyx®-Oil 2K Pure, which penetrate deeply into the pores.

What happens if too much material is applied to flooring?

If you apply too much Polyx®-Oil, the drying time will prolong considerably. If this happens, provide additional ventilation by opening windows and doors so that the product can dry naturally through oxidation. If damage occurs to the surface as a result, repair the surface as described above.

What happens if too little material is applied to flooring?

If you apply too little product, water spots may appear, the wood may dry out or look dull. In such cases, please apply another thin coat of Osmo Polyx®-Oil.

When is the floor accessible again?

Generally flooring is accessible one day after the final coat is applied. However, you must ensure that the final coat is dry to the touch. The surface will take 14 days to cure completely. As a result, rugs should first be placed on the surface after 2 – 3 weeks.

Does the floor need polishing once the top coat of Osmo Polyx®-Oil has been applied?

No, at this stage no further floor treatment is necessary. However, the surface can be buffed with a single disc machine (white pad) once completely dry. If a higher level of gloss is desired, the floor can be treated after one day at the earliest with Osmo Liquid Wax Cleaner and then polished.

How do I maintain my floor?

This all depends on how much it is used. For regular, gentle cleaning, we recommend adding Osmo Wash and Care to mop water. Osmo Cleaning Kit for Floors and Spray-Mop have proven to be invaluable tools for floor maintenance. If the floor starts to look dull and lifeless, simply restore it with Osmo Liquid Wax Cleaner. This can be done in small areas, e.g. near doors or on high traffic areas, without needing to restore the whole floor area as our products do not leave any visible transitions. If the signs of wear are more substantial, the floor should be recoated with Osmo Polyx®-Oil.


Which wood species should be impregnated in outdoor areas?

With impregnations the lifetime of woods with low durability can be increased dramatically. Especially coniferous woods, such as Spruce / Fir, Pine and Hemlock, are among these wood species.

Why does fungal attack (mildew) occur on wood finishes in outdoor areas and how can I remove it?

The most frequently appearing fungus shows up as a spotty, sometimes brownish, but mostly black attack. Moss and algae, in contrast, appear as a green film on the finish. These organisms discolor wood and might spread over the entire area. This attack is a result of high humidity and other environmental influences – particularly in shady areas and near plants or water. The wood will not be destroyed by this discoloring fungus. The film can easily be removed by using chlorine bleach with a chlorine content of 5% (available at local drugstores).

Do transparent color finishes offer UV protection?

Effective protection can be achieved with a transparent color finish in weathered outdoor areas. Darker pigmented finishes offer more UV protection than lighter pigmented finishes. A top coat with Osmo UV-Protection-Oil extends the lifetime of other Osmo finishes dramatically. As a general rule,
the higher the opacity, the higher the UV protection.

Is there a clear finish that offers UV protection in outdoor areas?

Yes, vertically installed wood in outdoor areas, such as siding and fencing, can be protected with a clear finish. Osmo UV-Protection-Oil contains special clear ingredients that do not allow UV radiation to affect the surface of the wood. The graying process is then delayed and the natural beauty and character of the wood is preserved.

How should I treat hardwoods rich in extractives (resins and oils)?

Exotic woods (Iroko, Massaranduba, Teak, Bangkirai, etc.) and highly resinous wood species (Larch and Douglas Fir) contain extractives that make the wood durable and provide resistance to fungus, blue stain and insects. The wood extractives may prevent binding agents (natural plant oils) from penetrating much like a release film and thereby increasing drying time and decreasing the life of the finish. Therefore, we recommend allowing the wood to weather for approx. 3-4 months before the application. An impregnation is usually not necessary due to the wood extractives. Our specialized Decking-Oil is designed to match the natural colors of the different wood species, enhance their natural features, and give them a refreshed, natural look and a smooth surface.

Note: For the treatment of larger areas, Osmo offers a special Decking Brush which enables a quick and easy application.


Can the colors of various Osmo finishes be mixed together?

Yes. The color of the respective product ranges can be mixed together in any ratio. For example, Osmo Country Colour 2404 Fir Green can be mixed with Osmo Country Colour 2703 Charcoal to create a darker shade.

How long does it take for the surface to dry?

Most Osmo products dry within 8 –10 hours. The surface dries through oxidation and absorption. Please ensure that there is sufficient ventilation for drying purposes.

Why does the finished wood surface look different than the color on the can?

Depending on the wood species they are applied on, the finished surface may have a different color. This color does not always match the swatch on the can. Before starting work on the complete area, we recommend applying the finish to a small trial area, which cannot be seen later, to check if the resulting color is what you want to achieve.

What surface properties are best for applying finish to wood?

The surface must be clean, dry (max. 20 % moisture content) and frost-free.

What does wood treated with Osmo products smell like?

After drying, your wood flooring will have a slight smell of wood and natural oils and waxes. As a solvent, we use dearomatized white spirit, which is less harmful to the health than so-called "Eco" solvents, such as citrus oils. The solvent dissipates 100% after drying and curing.

Do Osmo products contain harmful substances?

Osmo products are based on carefully purified natural oils and waxes. When dry, most of these surfaces are safe for humans, animals and plants (suitable for children’s toys according to EN 71.3 and resistant to saliva and perspiration according to German DIN 53160).

Note on the use of oil based wood finishes:
Cloths and material soaked with the liquid product should either be washed out immediately or stored in a closed airtight metal container (Danger of self-ignition!).
