For decking, cladding and other exterior applications

Protecting from the inside, Osmo End Grain Wax is absorbed into the natural fibres of the timber, blocking the movement of water in to and out of the board. Controlling the moisture in the timber in this way, Osmo End Grain Wax stabilises the board and prevents swelling and shrinkage of the timber in wet and dry conditions.

Application & Maintenance Advice

Application Areas

End Grain of decking, cladding or timber roofing applications of softwood and hardwood species such as Western Red Cedar, Pine, Larch, Douglas Fir, Spruce, Teak, Yellow Balau, Cumaru and Thermowood.


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

Osmo End Grain Wax is ready for application, do not dilute, stir thoroughly.


Osmo End Grain Wax is easily applied to the end grain with a thick brush.

To ensure optimal protection of the end grain, we recommend applying a secondary coat once the first coat has dried.

Please apply to end grain surfaces only. Excess wax can be wiped from other surfaces clean with a cloth.

Drying Time

About 3-4 hours (at 23°C / 50% relative humidity). At low temperatures and / or high humidity, please allow for an extended drying time.

After drying, it is recommended that the rest of the timber is finished with an Osmo wood finish such as:


Osmo End Grain Wax can be stored for up to 5 years if container is kept tightly sealed.


Natural products

Osmo uses food safe, natural ingredients for the basis of their wood finishes, waxes and pigments, including sunflower, soya, linseed and thistle oil, which is good for customers and wood alike.

Osmo products contain disaromatised white spirit to ensure finishes spread easily, removing the need for so called "Green solvent" materials which can cause allergies.

Natural beauty of oils and waxes

Wood is a natural material, the cell structure, similar to our skin, can take on and release moisture, it breathes. To ensure that this exchange is not prevented we have created finishes especially suited to the character of the wood.

Osmo natural wood finishes are based on oils and waxes, the oil penetrates into the wood surface, protecting from deep within. The waxes form an elastic, micro-porous surface which protects the wood from external influences. The wood remains naturally beautiful, protected and durable.
