Who is OSMO

OSMO is a German manufacturer based in Warendorf, North Rhine-Westphalia. The company Osmo Holz und Color has a history of more than 140 years that began with timber trading and a sawmill. Alongside wood products, it has been developing wood finishes since the late 1970s. Today it makes finishes for interiors and exteriors, for DIY users, tradespeople and industrial applications.

OSMO finishes are based on plant oils and waxes. They penetrate the wood and form a microporous surface that does not crack or peel, while the wood underneath can continue to move naturally.

Main product groups

Hardwax oils

Hardwax oil is intended for interior use on wooden floors, stairs and furniture. The surface resists water and dirt and is usually applied in two thin coats. It is available clear in several sheen levels, in coloured tints, and in an Effect version that keeps the look of raw wood.

Wood waxes and other interior finishes

Wood wax finishes are suitable for cladding, walls, ceilings and furniture, in transparent and intensive shades. The interior range also includes TOP oil for worktops and tables, oil stain for colouring floors before the top coat, and a wax finish with UV protection that slows the yellowing of light-coloured wood.

Decking oils

Decking oils protect horizontal wood outdoors. They come in shades matched to different wood species, such as Douglas fir, Bangkirai, Garapa, Massaranduba or red spruce. The range also includes an anti-slip hardwax oil for surfaces where safe walking matters.

Woodstains and UV protection oils

Natural oil woodstain and UV protection oils are designed for exterior wood such as facades, fences, carports, windows and doors. According to the manufacturer, UV Protection Oil Extra is intended for vertical surfaces, not decking. Transparent shades let the wood grain show through. Darker shades usually offer better protection from sunlight than lighter ones.

Country Colour

Country Colour is an opaque exterior finish for wood. It suits places where you want a uniform colour and the grain does not need to show, for example facades, fences or garden sheds.

Maintenance and accessories

The range also includes cleaners, a wood reviver for restoring greyed wood, impregnation, and application tools such as brushes, rollers and application pads.

How to choose the right product

Ask yourself four questions:

Interior or exterior? Exterior finishes must withstand sun and rain, interior finishes mainly wear and dirt.
Horizontal or vertical surface? Floors and decks take foot traffic, cladding and facades mainly take the weather.
What look do you want? Clear, a transparent shade or an opaque colour.
What wood are you finishing? The species and how much it absorbs affect the final shade and the consumption.

Always test the shade on your own wood first. Many OSMO finishes are available from us as a 5 ml sample for €2.

Caring for finished wood

Oiled surfaces are easy to maintain. Clean them regularly with a suitable cleaner and renew the finish at the first signs of wear. Renovation usually means cleaning the surface and applying one new coat, without sanding the whole area back to bare wood. How often depends on the load and the weather. Decks and surfaces facing the sun are the most exposed. The manufacturer gives exact procedures in the technical data sheet for each product.
