How to Paint Old Weathered Wood

Save

Weathered wood can be made to look new again by applying a fresh coat of paint. If you use an opaque paint, you can keep the aged look of the wood while adding color and giving the wood a protective coat. You can paint (or repaint) your barn, your shutters, an old bench or just about any other piece made with older wood. To paint old weathered wood, you will need to prepare the surface of the wood prior to applying paint.

Weathered wood can be repainted while preserving the aged look.

Things You'll Need

  • Cat's paw or hammer
  • Pencil
  • Paint scraper
  • Paint remover
  • 100 grit sandpaper
  • 220 grit sandpaper
  • Paint
  • Paintbrush
  • Tape
  • Sanding block (optional)
  • Oil-based primer (optional)
Step 1

Remove any nails or other metal objects from the wood, and assess the damage to the wood before you begin. Use your fingernail or a pencil to check the wood for rot by poking random areas of the wood. If the pencil goes into the wood more than one-eighth inch, the wood may need further treatment or may be discarded.

Step 2

Scrape the wood with a paint scraper to remove old paint or finish from the wood. If the old paint or finish does not come off easily, use a paint removing solvent available at any hardware store. If the wood is bare, skip to Step 3.

Step 3

Sand the entire surface of the wood with 100 grit sandpaper. This will clean the surface of the wood, allowing the paint to properly adhere to it. Repeat this process with 220 grit sandpaper to create a smooth and uniform surface.

Sand until uniform.

Step 4

Test the wood to verify the paint will adhere properly. In the article "Paint Problems on Exterior Wood" at Extension.iastate.edu., Iowa State University forester Dean Prestemon explains that you may perform a simple test. Paint a small area of the wood and allow it to dry for at least two days. Apply a piece of tape or other adhesive to the dried paint, and remove it in one swift movement. If paint sticks to the adhesive, repeat the cleaning and sanding steps. If the tape comes off clean, you are ready to paint the entire surface.
