Guide on How to Oil Your Oak Door

Preparing Your Door

Set Up Your Workspace

Ensure that before you begin, your workspace is clean, dry, and well-ventilated. Lay your door flat in this area to prepare for oiling.


Always test the oil or stain on a spare piece of wood or the underside of the door before full application. This ensures the finish meets your expectations without unexpected surprises on visible areas.

Applying Clear Hardwax Oil

First Coat

  • Clean the door thoroughly, ensuring it's dust-free.
  • Using a lint-free cloth, apply a layer of Treatex Hardwax Oil Clear evenly across all areas of the door. Be sure to wipe away any excess or drips.
  • Allow the door to dry for 24 hours.


  • After the first coat has dried, lightly sand the door to smooth out any imperfections.
  • Remove all dust and debris resulting from sanding.

Second Coat

  • Apply a second layer of Treatex Hardwax Oil Clear.
  • Allow another 24 hours for drying.

Additional Coats

If the door will be fitted in a bathroom or a high-moisture environment, a third coat is recommended to ensure extra protection.

Applying Colour/Stain

First Coat of Stain

  • After preparing the door as above, apply your chosen stain or colour evenly using a lint-free cloth.
  • Wipe any excess as you work to ensure an even coat.
  • Allow to dry for 24 hours.

Sanding and Second Coat

  • Lightly sand the door to prepare for further treatment.
  • If a deeper colour is desired, apply a second coat of stain. Allow it to dry as before.

Clear Coat Application

  • Apply a coat of Treatex Hardwax Oil in Clear over the stained areas to seal and protect the colour.
  • Sand lightly between coats if necessary.
  • Apply a second clear coat for optimum protection and finish.
  • Allow the door to dry completely.

Final Steps

Once the final coat is dry, your door is ready to fit or hang. Remember, the key to a professional-quality finish is patience between coats and meticulous preparation.


  • Always ensure proper ventilation during application and drying.
  • Follow all manufacturer's instructions and safety guidelines for the best results.

By following these detailed steps, your oak door will not only look splendid but also stand up to the rigours of daily use, maintaining its appearance and integrity over time.
