How to Apply Fiddes Exterior High Build Wood Oil

Correct preparation and application are important to achieve a durable exterior finish.

  1. Prepare the surface: Ensure all timber is clean, dry and free from previous finishes.
  2. Clean old timber: Remove fungal growth, dirt and moss from existing wood before application. Ensure the timber has been treated with a suitable wood preservative.
  3. Sand the timber: Prepare the surface using medium 120-grit sandpaper or a 120-grit sanding disc, removing all traces of sanding dust.
  4. Choose suitable conditions: Apply Fiddes Exterior High Build Wood Oil only in dry conditions. Ensure the timber is dry before starting.
  5. Stir thoroughly: Stir the contents well before and during use.
  6. Apply the oil: Use a good-quality bristle or synthetic brush, applying evenly and thoroughly in the direction of the grain.
  7. Seal all areas: Ensure all areas are completely coated, including exposed timber surfaces.
  8. Allow to dry: Leave to dry for 4–6 hours or preferably overnight.
  9. Sand between coats: Lightly sand using fine 320-grit sandpaper.
  10. Apply further coats: A minimum of three coats is recommended. Allow the oil to dry between applications.

Coverage and Drying Time

  • Coverage: Approximately 20–24m² per litre per application, depending on the density of the timber.
  • Drying time: 4–6 hours or preferably overnight between coats.
  • Recommended coats: Minimum of three coats.

Please note that longer drying times may occur in damp or humid conditions. Always test on a small area before treating the entire surface.
