Knotty Alder Doors

We recently had a request on how to faux paint a steel door to look like knotty alder.   
Here is a summary of steps.
  • Prepare the door by repairing the  dents and imperfections with several coats of Bondo.      Skim coats are the best.   Allow each skim coat to dry then lightly sand it smooth. Continue to apply the skim coats until the surface is smooth and imperfections are gone.
  •  Seal the repaired imperfections with a spot primer.
  • Apply under coating and allow it to dry.  The color of knotty alderwood you want will determine the color of undercoats and final coat you use. 
  • Continue to apply undercoatings of different color to obtain the depth and richness you desire.
  • Apply a final coat and hand draw the wood grains and knots.
  • Allow the final coat to dry thoroughly.   This time will vary depending on the weather and temperature.
  • Apply a clear sealant coat to protect the wood design.
There are books available to help you.  They describe the process with more details and pictures.  If you are willing to take the time, it can be a very satisfying project.
Here is an example of metal casings, woodgrained to match the real knotty alder wood doors.
