How to Stain an Exterior Mahogany Door

Mahogany exterior doors are beautiful on their own, but there are times when you might want a darker finish. That is certainly possible, but it is important to remember that you can only stain wood to a darker finish. In order to lighten the finish, paint must be used and the procedure is different. Staining exterior doors is a fairly simple process that can be completed in a day's time.

Mahogany exterior doors can be stained a darker color, but not lighter.
  1. Ensure that the exterior mahogany door is clean and dry. The door should be placed in a well-ventilated area that will remain dry until you are done staining it.

  2. Sand your mahogany exterior doors with fine grit sandpaper to scruff the surface of the door.

  3. Apply a layer of stain and filler combination to the entire door with a high quality paintbrush. The stain and filler combination can be found at building supply stores. It will help fill the pores of the wood and create a smooth base. Allow the filler to dry for four to six hours.

  4. Stain the exterior door with an alkyd-resin based stain and sealer combination using a high quality paintbrush. Wait 4 to 6 hours for the stain to dry.

  5. Sand the door lightly with fine grit sandpaper and apply a second coat of stain. Again, allow the stain to dry for four to six hours. If a third coat of stain is required, sand the door lightly between coats.
