Are Osmo products certified?

Are Osmo products certified?

Osmo products are in accordance with, and certified to, relevant VOC-regulations as per DIN EN ISO 9001:2000 (Quality management systems) and 14001 (environmental management systems), demonstrating that Osmo, as a responsible manufacturer of wood and wood finishes, is committed to developing itself and it's products to meet both the ecological and economic challenges which are faced in modern times. Due to the low amounts of solvents used in our products, the Osmo production facility has not been bound by the German emissions law since 1998, in addition to these technical systems are also encapsulated to ensure that very little emissions can enter the atmosphere.

Where are Osmo products made and how?

Where are Osmo products made and how?

The principal office is located in Warendorf and the production takes place in Warendorf and Münster, Germany. Osmo products are distributed by more than 2500 specialist dealers in Germany and in numerous countries in Europe and all over the world.

The foundation of Osmo wood finishes has been based upon purified and refined natural resources throughout the last 30 years. The dry finish fulfils both the DIN EN 71.3 (suitable for children's toys) and DIN 53160 (fast to perspiration and saliva) and as such is safe for humans, animals and plants. Osmo uses carefully harvested natural oils (sunflower, soya, linseed and thistle oil) and hard waxes (carnauba and candellila wax) for its finishes. The inorganic pigments used for Osmo Color are created from natural ores, these are cleaned and refined until a level of physiological purity has been achieved and only a pure mineral element remains.

Osmo has been working for many years with "High Solid Products" which contain only a small amount of solvent. For years now Osmo has also been working to develop products which are completely free from solvents (VOC's), as a result of this research the Osmo "Full Solid" range of products was launched, Osmo is still striving to develop this technology further for the years to come.

What would happen if I did use Osmo over another finish?

What would happen if I did use Osmo over another finish?

It is likely that the old finish will slow down or block the penetration of the Osmo finish. This could cause extended drying times, as well as creating a sticky or tacky wood surface. Also, if there is excess oil or wax on the surface of the wood then the surface can easily be scratched. To rectify this, we would recommend using white spirit and a cloth to help the finish penetrate and also remove any excess. If this does not resolve the problem then sanding is necessary and re-application onto a clean, dry and raw wood surface.

Can I use Osmo finishes on top of other finishes?

Can I use Osmo finishes on top of other finishes?

We recommend applying Osmo finishes onto a clean, dry and raw wood surface for first application for best results possible. We recommend cleaning or slightly sanding any old microporous finishes such as oils or waxes. But, varnish or lacquers must be fully sanded as these types of finishes can block the penetration of the Osmo finishes. Small cracks and small holes in the wood can be filled using Osmo Wood Putty. Sand carefully before application starting with a coarse paper, final sanding for flooring P100-120, for furniture P150-240. Remove any dust thoroughly from the surface before application using a vacuum cleaner and apply the Osmo finish accordingly.

What is the difference between Osmo Polyx Oil Tints and Osmo Woodwax Transparent?

What is the difference between Osmo Polyx Oil Tints and Osmo Woodwax Transparent?

Osmo Polyx Oil Tints is normal Polyx Oil (satin) which contains a very small amount of coloured tint. It gives a very faint coloured effect. Polyx Oil Tints is a finish in it's own right - just like normal Polyx Oil.

Osmo Woodwax Transparent is a one coat, coloured transparent stain, which contains approximately three times the amount of pigment as Polyx Oil Tints, thereby giving a greater depth of colour to the timber. Being a stain, it penetrates the timber, but still requires a clear finish such as 2 coats of Polyx Oil over the top. 

If you require a faint washed coloured effect, then Polyx Oil Tints is the product to use. If you require a deeper colour, then Woodwax Transparent is recommended, with 2 coats of normal Polyx Oil over the top.

Can you please explain the difference between using your Osmo product as compared to using a polyurethane or Tung Oil. Thanks.

Can you please explain the difference between using your Osmo product as compared to using a polyurethane or Tung Oil. Thanks.

There are 3 main types of floor finishes. An oil will penetrate and nourish the timber, but will not form a film on the surface. Maintenance of oiled finishes is high. A polyurethane or varnish type finish forms a film on the surface of the timber. It does not penetrate into, or nourish the timber. If the flooring timber moves, the polyurethane will crack, and the floor will need resanding. An oil and wax combination finish such as Osmo Polyx Oil is the best of both worlds.

Hi.. thanks for the question. Tung Oil has no UV stability, so it is not recommended for use outside in its pure form. The better option would be Osmo's UV Protection Oil Clear, which is safe for children's toys.

Your timber needs to be thoroughly cleaned first to remove any blackening such as mould and dirt from the timber. A product such as Osmo Power Gel Timber Cleaner is ideal for cleaning your patio setting. Once clean and dry, we recommend using Osmo UV Protection Oil. This is available as a clear finish or in the colour tones of Oak, Cedar and Natural.
