Preparation

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.

1. Old paints and varnishes must be fully removed with a suitable paint and varnish remover prior to application of Osmo One Coat Only
2. Old microporous stains need only be cleaned or lightly sanded
3. Remove any mould or algal growth
4. For wood that has turned silver / grey due to weathering, pre-treat with Osmo Wood Reviver Gel
5. Fill any holes or imperfections in the wood

Application

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.

1. Apply Osmo One Coat with an Osmo Brush or Osmo Microfibre Roller
2. If using a brush, only dip the brush a little into the tin and apply very thinly along the wood grain
3. Apply the product thoroughly and evenly, and allow to dry for approximately 12 hours with good ventilation
4. Remove any excess product immediately with a clean lint-free cloth

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.

Aftercare

Regular Cleaning

Light marks and dirt can be removed by cleaning the affected surface with a mixture of water and Osmo Wash And Care.
