The Evolution of Osmo Wood Finishes
In 1964, Osmo began developing durable, high-quality wood finishes to improve on traditional lacquers and varnishes that cracked and peeled. This research led to the launch of Wood Wax Finish Clear Extra Thin in 1978, the world’s first brushable oil/wax, and in 1997, the groundbreaking Polyx®-Oil became the first finish to combine oil and hardwaxes into a new type of durable finish now known worldwide as “Hardwax-Oil”.

Polyx®-Oil Sheens
Note: The colour shades shown are a true likeness of the original, after application onto Oak. However, some variation may occur due to screen brightness and uploading processes. It is advisable to test colours on a small sample, as colour may appear differently on other wood species.
Looking for some colour?
Our Polyx®-Oil Tints are the coloured version of Polyx®-Oil, available in eight shades with a matte finish. To change the sheen, Polyx®-Oil Tint can be top-coated with Polyx®-Oil.
Application Methods
Different species of wood require different amounts of product to achieve the highest durability and stain resistance. This is especially important for finishing high-traffic areas like flooring, stairs, countertops, and cutting boards.
Wood species and their recommended application amounts →
Different applicators will provide different results in regard to colour and the number of coats needed. Choose the best application method or mix and match to achieve the recommended amount of finish for your chosen wood species.
Microfibre Roller = Applies 30g/m² per coat – fastest application. 2 coats recommended.
Flat Brush = Applies 20g/m² per coat – best for textured surfaces and colour. 2-3 coats recommended.
Oil Applicator Fleece = Applies 15g/m² per coat – user-friendly, small build, medium colour intensity. 3 coats recommended.
White Superpad = Applies 10g/m² per coat – minimalist finish, lower product waste, can be buffed to high luster. Not recommended for high-wear surfaces.
Cloth = Applies 5g/m² per coat – minimalist finish and creates subtle colours. Not recommended for high-wear surfaces.
Before applying any Osmo finish, proper sanding is essential. For step-by-step guidance and expert tips on preparing flooring, furniture, and exterior wood, visit our Sanding Preparation page.
Stir the finish well prior to use.
- Using the Osmo Microfiber Roller, or Osmo Floor Brush, apply Polyx®-Oil thinly and evenly in the direction of the grain.
- Do not remove excess product, this will absorb into the wood surface over the drying period.
- Drying time approx. 8 – 10 hours (normal climatic conditions, 73°F / 50% rel. humidity). Lower temperatures and/or higher humidity can affect drying time. Ensure space is well ventilated.
Second Coat:
- Apply the second coat of Polyx®-Oil thinly and evenly, as before. Remove excess product after 5 – 10 minutes. Alternatively, you can apply the second coat with a scraper and buff the surface with a clean white pad.
- Allow 8 – 10 hours drying time.
- When thoroughly dry, the surface can be buffed or polished with a hand polisher or floor buffing machine.Note: For high-quality finishes on items like tabletops, a smoother result can be achieved by lightly sanding the surface after the second coat has fully dried with a P320 or P400 grit sandpaper, and then buffing 1-2 extra coats with a cloth or white pad.
Third Coat: Usually, a third coat is not required; however, highly absorbent or dry timbers may appear to require a third coat.
Please consult OSMO technical support at 1-844-OSMOCAN prior to carrying out a third coat
Cure Period: Osmo Polyx®-Oil(s) like all finishes, have a cure period. We recommend allowing 2-3 weeks for the surface to fully cure and harden before damp-mopping or placing rugs/mats on the surface.

Apply 2-3 thin coats with an Osmo Fleece Applicator.
Stir the finish well prior to use.
- Using an Osmo Fleece applicator, work Polyx®-Oil thinly and evenly into the surface. A Fleece applicator is the best method for ensuring you avoid over-application and doesn’t require the product to be buffed out or excess removed.
- Drying time approx. 8 – 10 hours (normal climatic conditions, 73°F / 50% rel. humidity). Lower temperatures and/or higher humidity can affect drying time. Ensure space is well ventilated.
Subsequent Coats: Apply following Polyx®-Oil coats thinly and evenly, as before.
Note: If high durability is required (ie. Floors and Tabletops) we suggest applying Polyx®-Oil using the Brush or Roller technique.

Apply 3-4 thin coats with non-abrasive white scotchbrite pads.
Stir the finish well prior to use.
- Using a White Scotchbrite Pad, work Polyx®-Oil thinly and evenly in figure 8 or circular motions.
- Wait for 5-10 minutes for the product to absorb into the wood surface.
- With a clean White Scotchbrite Pad, polish the surface ensuring no swirl marks, rings, or wipe marks are visible and excess product has been removed.
- Drying time approx. 8 – 10 hours (normal climatic conditions, 73°F / 50% rel. humidity). Lower temperatures and/or higher humidity can affect drying time. Ensure space is well ventilated.
Subsequent Coats: Apply following Polyx®-Oil coats thinly and evenly, as before.
Note: Depending upon the species of wood (ie. Walnut) it may not be possible to achieve full durability and stain resistance when applying with a pad. If high durability is required (ie. Floors and Tabletops) we suggest applying Polyx®-Oil using the Brush or Roller technique.

Apply 4-6 thin coats with a lint-free microfibre cloth like Osmo Easy Pads.
Stir the finish well prior to use.
- Using an Osmo Easy Pad or a lint-free microfibre cloth, work Polyx®-Oil thinly and evenly in figure 8 or circular motions.

- With a clean cloth, remove excess product from the surface.
- Drying time approx. 8 – 10 hours (normal climatic conditions, 73°F / 50% rel. humidity). Lower temperatures and/or higher humidity can affect drying time. Ensure space is well ventilated.
