The first time I decided to repaint my interior doors, I was staring down a set of old ‘70s or ‘80s veneered wood flat doors that had definitely seen better days. I remember wondering, “Can I really make these look good?” After trial, error, and practice, I’ve learned a reliable method for painting doors—no matter what style you’re starting with. From old flat veneers to paneled and French doors, here’s my step-by-step guide to help you achieve a fresh, polished look.

How to Paint Interior Doors Step-by-Step
1. Identify Your Door Type
Before you dive in, take a moment to size up what you’re working with:
- Old Veneered Flat Doors: Often found in older homes, these might have chips or scratches that need a little TLC.
- Paneled Doors: Raised or recessed panels mean a bit more attention to detail.
- French Doors: Multiple glass panes call for careful taping and a steady hand.
- Hollow-Core Doors: Lightweight and smooth, these are usually the easiest to paint with a roller.
Understanding your door type helps you tailor your approach for better results.
2. Prepare the Surface
I’ve found that proper prep is half the battle. Look after these things before you begin to prime or paint:
- Remove hooks
- Wipe down the door with a damp cloth
- Tackle any grime with a gentle degreaser if needed
- If you see scratches or chipped veneer, use wood filler and sand once dry. This is especially important for older flat doors to create a smooth base.
3. Prime if Necessary
If you’re dealing with a major color change or painting over darker finishes, consider using a primer. Many high-quality paints include a built-in primer—I’ve had great success with these on veneer doors—but if in doubt, a separate primer can ensure even coverage and durability.
4. Gather the Right Tools
Quality tools matter. I like angled brushes for detail work and a foam roller for large, flat areas. Foam rollers give a smooth finish on flat and hollow-core doors, while an angled brush is perfect for getting into the grooves of paneled or French doors.
5. Plan Your Painting Technique
Apply the paint in thin, even coats—patience pays off:
- Flat/Veneered Doors: Use a foam roller with long, even strokes.
- Paneled Doors: Start with the panels and recessed areas, then do the horizontal and vertical sections, painting with the grain.
- French Doors: Tape off the glass, use an angled brush, and go slowly.
- Hollow-Core Doors: Similar to flat doors, a roller usually does the trick, with a brush for edges, if needed.
6. Don’t Rush the Dry Time
Let each coat dry fully according to the manufacturer’s instructions. Multiple thin coats will always give you a better result than one heavy coat.
7. Address Edges and Hardware
If possible, remove the door from its hinges and hardware to lay it flat before you begin. This makes achieving a smooth finish easier. If not, carefully tape around hinges and knobs to keep them clean.

FAQs
You can—laying it flat makes for a smoother finish—but you can paint it in place if you’re careful and tape off hardware.
Two coats typically provide good coverage, but if you’re covering a dark color with a light one, a third coat might be needed.
Often, yes. Still, if you’re covering a very dark finish or dealing with stains, a dedicated primer can help ensure the best result.
I prefer satin or semi-gloss because they’re easy to clean. Gloss can add drama, while matte feels more understated. It’s all about your personal style.
