Osmo Natural Oil Woodstain Effect is ideal for any exterior wood, including doors, windows and window shutters, carports, timber cladding, balconies, fences, pergolas, garden furniture and summer houses.

The transparent colour tone of Osmo Natural Oil Woodstain Effect will be influenced by the woods natural colour, causing the result to deviate from the colour shown on the colour chart. Lightly pigmented transparent finishes have limited protection against UV influences and are therefore not recommended for surfaces prone to strong sunlight.

All colour shades can be mixed with each other to achieve alternative shade variations.

Wooden surfaces to be treated with Osmo Woodstain must be frost-free, dry and free from surface dirt and debris before application.

  • Existing oiled surfaces can be lightly rubbed back with meths then fully cleaned
  • Pre-existing varnishes and sealers must be completely removed via sanding or using a suitable Product Stripper / Remover
  • Use an appropriate porous filler if repairing small dents and holes
  • To protect against blue stain in moist surroundings pre-treat with biocide-free wax impregnation, Osmo WR Base Coat 4005

Always do a test area before starting any project. Follow the manufacturer's instructions on the tin at all times. Stir well before and periodically during use. Osmo Natural Oil Woodstain Effect is ready to use and does not require thinning. Be aware that rough sawn timber is more absorbent, meaning coverage per litre will be greatly reduced.

  1. Apply Osmo Natural Wood Stain thinly and evenly along the wood grain with a good quality hand brush or microfibre roller
  2. Allow good ventilation whilst drying
  3. Apply a second coat as before once the first coat has dried

Please Note: Dried surface is satin-glossy at first and afterwards is satin.

To increase the durability of the finish and improve UV resistance we recommend, after thorough drying, the application of Osmo UV Protection Oil 420 Extra as a top coat.


If renovating, simply re-apply a thin coat of Osmo Natural Oil Woodstain Effect to the clean, dry surface.

Great product by Gloucestershire Harris

Having used another Osmo product on internal flooring was not disappointed on using Osmo Natural Oil Woodstain Effect on our new log cabin. Although expensive it goes a long way.
