How to Paint a Door Correctly

A freshly painted door transforms the look of a room instantly. But painting a door correctly — without drips, brush marks, or peeling — requires the right prep, tools, and technique. Here's how to do it like a pro.

What You'll Need

Paint (interior or exterior grade as appropriate)
Primer (if painting bare wood or changing colors dramatically)
Painter's tape
Paint roller (4" foam roller for flat panels)
Angled brush (2" for edges and details)
Sandpaper (120 and 220 grit)
Tack cloth

Step 1: Remove the Door (Recommended)

Painting a door flat on sawhorses gives a much better result than painting it vertical. Gravity causes drips on vertical surfaces. Remove the door by tapping out the hinge pins from the bottom with a screwdriver and mallet.

Step 2: Remove Hardware

Remove the door knob, latch, and any other hardware. Tape over hinges if leaving them in place. This prevents paint buildup on hardware and gives cleaner edges.

Step 3: Sand and Clean

Sand the door with 120-grit to scuff the existing finish, then wipe with a tack cloth. For bare wood, sand to 120, then 220. Clean off all dust before painting.

Step 4: Apply Primer (If Needed)

Prime bare wood, stained surfaces, or when making a dramatic color change. Let dry fully per manufacturer instructions before painting.

Step 5: Paint in the Correct Order

For a paneled door, paint in this order to avoid lap marks:

Recessed panels first (brush)
Horizontal rails (brush or small roller)
Vertical stiles (brush or roller)
Door edges last (brush)

For a flat door: use a foam roller on the face, brush on the edges.

Step 6: Apply Thin Coats

Two thin coats always beat one thick coat. Thick coats drip, sag, and take forever to dry. Apply the first coat, let dry fully (check manufacturer time), lightly sand with 220-grit, wipe clean, then apply the second coat.

Step 7: Let Cure Before Closing

Paint may feel dry to the touch in 1–2 hours but takes 24–48 hours to cure enough to close without sticking. Leave the door open or off its hinges during this time.

Pro Tips

Use a foam roller for the flattest finish with no brush marks
Paint the door edges the same color as the room it opens into
Always paint the top and bottom edges to seal against moisture
Remove painter's tape while paint is still slightly wet for cleanest edges
