Before opening the 5ml sample sachets, squeeze the packet several times to ensure that the oil and pigments inside are thoroughly mixed.
Please Note: Using this product on rough sawn or featherboard wood will significantly reduce it's coverage.
Ensure that the wood surface to be treated is clean, dry (maximum moisture content 20%) and free from dust, dirt or any other surface contaminants.
Always do a test area before starting any project to check suitability and compatibility. Follow the manufacturer's instructions on the tin at all times.
Osmo One Coat Only HS Plus should be brush or roller applied only. It is not suitable for spray application. Stir well before and during use for a consistent finish.
Please Note: If applied too thickly, this product may leave shiny areas. However, these shiny areas will weather naturally within a short period of time, leaving an even, satin-matt appearance.
For windows or other surfaces exposed to weathering, apply a coat of Osmo UV Protection Oil Extra over One Coat HS Plus when fully dry. This will give the surface a slightly satin appearance and improved durability of the finish. If possible apply to all sides of the wood.
