How to Paint a Door


So you’re looking to paint door pieces (or the entire door) by yourself? Buckle up, this can be a rewarding experience, but if it’s not done correctly, it can be a massive, expensive headache. That’s the exact reason why we wrote this article: so you can save money, time, and frustration whenever you paint doors in the future.

When you’re getting ready to paint a door (whether you’re talking interior doors or exterior doors), starting off with the right prep work is key if you want to end up with a professional-looking finish.

It’s super important to pick the right tools and materials because they really make a difference in how your project turns out. For instance, if you’re using water-based paint, go for synthetic brushes, but if it’s oil-based paint, natural bristle brushes are the way to go.

Also, you need to get the door ready by cleaning it, sanding it down, and applying a primer. This sets up a great base for painting.

Next, we’ll look into how to actually paint the door and the best techniques to use to get a smooth and lasting finish. This guide will cover everything needed for a successful door painting project.

Key Takeaways

  • Pick the right brushes and rollers that match the paint you’re using.
  • Take the door off its hinges and lay it flat somewhere easy to work on.
  • Give the door a good clean and sand it smooth before you start painting.
  • Use painter’s tape along the edges to keep your paint lines neat and tidy.
  • When you paint the door, start at the top and work your way down to prevent any drips.

Choosing the Right Tools


Choosing the right tools is key if you want your painted door to look like a pro did it. Go for top-notch brushes that match the paint type you’re using. For water-based paints, synthetic brushes are the way to go, and for oil-based ones, you’ll want natural bristle brushes.

A small roller is super helpful too; it helps you get a smooth, even finish on the flat parts of the door, cuts down on brush marks, and makes the job quicker. Also, don’t forget a solid paint tray and some painter’s tape to keep those edges neat and clean.

Spending a bit more on good tools not only makes the job easier but also makes sure your door turns out looking great.

Preparing Your Workspace


Before you start painting doors, it’s important to set up a clean and tidy area to work in. This helps everything go smoothly and safely. If you can, pick a spot outside or in a room with plenty of air flow to avoid breathing in too many fumes.

Put down some old sheets or newspapers on the floor to catch any paint splashes. Also, arrange all your painting supplies like paint cans, brushes, and rollers in one spot where you can reach them easily, but keep them a bit away from where you’re painting to prevent any messes.

Make sure there’s enough light so you can see all the small details of your work, whether it’s from the sun or a lamp.

Removing the Door and Door Hardware


To make painting easier, it’s a good idea to take the door off its hinges.

First, find the hinge pins. You might need something like a flathead screwdriver or even a small hammer to help get them out.

Slide the tip of the screwdriver under the head of the pin and give it a gentle tap with the hammer until the pin comes up a bit. Then you can pull it out the rest of the way. Do this for each hinge.

When the pins are out, grab the door firmly—it’s handy to have someone help you with this—and lift it off the hinges.

Before proceeding, also remove or protect the door hardware and door knob to prevent paint from getting on them. This step is crucial for those working with specific brass + crystal door hardware, ensuring a clean reinstallation post-painting.

Put the door on some sawhorses or lay it down on a flat surface with a drop cloth underneath to keep it from getting scratched or dirty.

Cleaning, Sanding, and Using Painter’s Tape


Alright, once you’ve taken the door off its hinges and have it set up nicely, the next thing you’ll want to do is get it clean and smooth so the paint sticks well. Start by wiping the door down with either a degreaser or some mild soap and water. This gets rid of any dirt, oils, or other gunk that might mess with the paint job.

Next up, grab some fine-grit sandpaper, something like 120 or 150 grit should do the trick. It’s crucial to sand the entire door, going along with the wood grain instead of against it. This ensures the entire door surface is smooth and helps prevent any scratches that might show up after you paint. Sanding the entire door makes the surface nice and smooth, which is key for getting the paint to stick.

After you’re done sanding, be sure to get all that dust off. You can use a tack cloth or just a slightly damp rag to wipe it down. This step is super important because you don’t want dust particles under your fresh paint.

Fixing Imperfections


Before you start painting your door, it’s important to fix any dents or holes. First, take a good look at the door to spot all the imperfections.

For small dents and holes, use a putty knife to fill them in with some wood filler. Make sure to put a bit more filler than you think you need, as it tends to shrink when it dries.

You’ll need to wait a few hours for the filler to set, depending on the weather and the type of filler you’re using. Once it’s dry, grab some fine-grit sandpaper and sand down the filled spots until they’re nice and smooth, blending in with the rest of the door.

This step is super important if you want your door to look great and make sure no previous flaws show through the paint.

Applying the Paint for Painting Interior Doors and Exterior Doors


After you’ve got the door ready and smooth, start with a primer if the door hasn’t been painted before or if you’re switching up the color. Priming is key because it helps the paint stick better and makes sure the finish looks even and lasts longer, and if you can use a primer with the same paint color, it’ll make finishing a lot easier. Primer is super important because it helps your paint adhere to the door, and if you skip this step, don’t be surprised when you start experiencing peeling paint.

Let the primer dry completely, which usually takes around an hour or two, depending on the type and the weather (if you’re doing exterior paint, an interior door typically doesn’t see any weather). Next up, put on the first coat of paint. Applying a fresh coat of paint can significantly transform the appearance of your door, offering a revitalized and updated look. Pick a paint that’s good for doors, like enamel or something made especially for doors and trim. This will give you the best look and make sure it holds up well. For better coverage and a polished finish, it’s advisable to apply a second coat of paint, ensuring the first coat has dried fully. This step is crucial for achieving an even, professional-quality finish.

Don’t forget to stir the paint well before you start painting to keep the color and thickness even.

Techniques for Smoothness


To get a really smooth, professional look on your painted door, try a few simple tricks to keep everything looking even and free of brush lines.

Start with a high-density foam roller—it spreads the paint nicely and avoids the usual brush marks. For the more detailed spots, like around panels and moldings, a good angled brush can really help. It gets right into those tight corners without leaving a glob of paint.

Make sure you always paint along the grain of the wood. This helps keep the natural look of the wood and stops any odd marks that go against the grain.

Also, it’s better to go for several light coats of paint rather than one heavy one. This approach helps prevent drips and keeps the texture nice and even.

Drying and Reattaching


After you’ve painted the door, make sure it’s totally dry before you hang it back up. This stops the paint from getting messed up or sticking.

Here’s what to do next:

  1. Test if it’s Dry: Just give the edge of the door a gentle tap with your finger. If it doesn’t feel tacky and nothing comes off on your finger, it’s good to go.
  2. Put the Hardware Back On: Now, put all the hinges, handles, and locks back on. Take it slow so you don’t chip the new paint.
  3. Hang the Door Up Again: Pick up the door, line it up with the frame, and attach it back in place. Make sure it swings open and shut nicely without any hitches.


To wrap things up on how to paint a door, painting a door is like sprucing up a boring room; it really makes your home pop. For your next door painting project, all you need are the right tools, a set-up space, and careful painting to turn a basic door into something eye-catching.

Being patient while the paint dries ensures it lasts and looks top-notch. Keep in mind, nicely painted doors don’t just make a room look better, they also boost your home’s overall charm.
