Painting your home’s wooden exterior doors is a great way to refresh the appearance of your house or reinvent your home style. And here’s the best part: if your doors are in good repair, you can have a fresh coat of paint on them in no time!

This is how to paint your exterior wood door in 7 easy steps:

1.Grab Your Supplies

To get the best quality finish possible, you’ll need to pick up a few things at your local GNH Lumber. One of the handiest things for this process is an orbital sander. This will save you hours of work and ensure a smooth, ready to paint surface.

Here’s your shopping list (you can also re-use these supplies for painting furniture or other surfaces around the house):

  • Wire brush & Scraper
  • Orbital sander (this will make the process much easier)
  • 60 and 120 grit sandpaper for sander
  • Dust mask or respirator
  • 2-inch paint brush
  • Wood putty (if you have spots you need to fill in)
  • Exterior Primer
  • Exterior Paint

2. Scrape and Sand

Before painting, you will want to scrape and sand the wood door. You don’t ever want to paint over peeling and chipping paint. Using your wire brush and scraper, you’ll want to remove as much paint as possible. Although this is a little bit of work, you should know that 80% of getting a great result lies in properly prepping the surface.

This is the fun part!  Pull out your orbital sander and apply a 60-grit sanding paper disk. This should remove any remaining paint from the surface. You will also want to make sure you get around the hinge and door knob areas too. This may involve removing the knob itself.

Some sanders have a microfilter system that sucks in the debris, but it’s highly advised that you also have a dust mask or respirator on. Even with the dust mask or respirator, there will still be a lot of debris in the air. Put safety first.

4. Make the Surface Smooth

This is an important step and you’ll want to take your time. Apply the 120-grit sandpaper and move the sander gently over the surface. You don’t need to press hard to get the job done. You’ll want to see and feel a flat surface that is free from nicks and gouges. If you have any deep nick and gouges left in your door after sanding, you will need to fill them in.

5. Fill in Nicks

After you have sanded the area, take wood putty, fill in the nicks, scrapes and gouges. After it dries, go over it again with the sander so that it blends with the wood. Yes, it may be a different color but it will be covered in paint so don’t worry. (If you don’t have any nicks and gouges, you can skip this step).

6. Priming

Next, you will want to apply a primer to your exterior door. This will adhere to the wood, seal it, and provide a smooth surface for your paint to adhere to easily. You’ll want to start at the top and apply it in a downward motion. Use nice, even brush strokes, covering the entire surface with thin coats.

7. Painting

Once your primer dries, you can apply your paint color. Remember to use even strokes, starting at the top of the door and go down towards the bottom. Watch for drips and make sure to use long brush strokes. This gives you an even coat that will dry smooth.

Once you’ve painted the surface, all that’s left is to let it dry and then reapply any hardware. Note that if there are high-humidity levels, you might need a little extra drying time!
