Doors are one of the most unforgiving surfaces in a house. Every brush mark, drip, and missed spot shows at eye level under direct light. The good news: a clean, professional-looking painted door is well within reach once you understand the prep, the products, and the painting order. This guide covers everything from removing door hardware to rolling on the final coat of paint, with specific product picks from Paint Outlets and tips that work for both trim and door paint projects.
Key takeaways
1. Remove all door hardware and lightly sand glossy surfaces before any paint touches the door.
2. A bonding primer is essential on bare wood, metal doors, and previously painted doors with a glossy finish.
3. ADVANCE® Waterborne Interior Alkyd is the go-to for interior doors, delivering oil-like leveling with waterborne cleanup.
4. Use a 2-inch angled brush for door panels and detailed areas, and a 1/4-inch nap mini foam roller for flat surfaces.
5. Paint a front door early in the day so it can dry without having to be closed while wet at night.
Why door painting demands better prep than walls
A wall forgives minor inconsistencies because you view it from a distance and at varying angles. A door sits at arm's length, catches sidelight across its flat surfaces, and gets touched, bumped, and swung open hundreds of times a week. That combination of close visibility and heavy wear is why door painting starts well before you open a can.
Skipping sanding on a glossy surface is the most common mistake. Paint cannot bond properly to a slick finish, and the new paint peels or chips within months. The same applies to dust, grease, and old paint residue. Spending an extra thirty minutes on prep saves the headache of stripping and redoing the entire door later.
How to prepare a door for painting
Start by removing all door hardware: hinges, handles, strike plates, and any door stops. If you can take the door off its hinges and lay it flat on sawhorses, do it. Painting flat prevents drips and runs.
Clean the entire door with soap and water, then wipe it down with rubbing alcohol to cut any grease or silicone residue. Fill gouges and nicks with wood filler, let it cure, and then sand smooth. For previously painted doors in decent shape, a light sanding with 220-grit sandpaper is enough to scuff the old paint and give the new paint something to grab.
Bare wood or rough surfaces benefit from starting with 120-grit, then finishing with fine grit 220. Wipe away all sanding dust with a tack cloth before moving on to primer.
Do I need to primer a door before painting?
Yes, in most cases. Primer blocks old colors, seals bare wood, and gives your topcoat stronger adhesion. It is especially critical on bare wood, metal doors, and any surface with a glossy or semi gloss finish that resists new paint.
For slick surfaces like a previously painted door with a high-gloss finish, a standard primer may not cut it. Stix® Waterborne Bonding Primer is purpose-built for hard-to-coat substrates. It bonds to glass, tile, PVC, and metal, so a glossy old paint surface is well within its range. Apply one coat, let it cure for 24 hours, then topcoat. Browse the full range of options in the interior primers collection when you need stain-blocking or specialty products.
If the previously painted surface is in good shape with a similar or darker color, a light sanding alone may suffice. A bonding primer is still the safer move when in doubt.
What kind of paint do I use on a door?
A standard wall paint (flat, eggshell, or matte latex paint) is not the right paint for a door. Doors need a harder film that resists chips, scuffs, and fingerprints. That means a trim paint in a semi gloss or satin finish.
ADVANCE® Waterborne Interior Alkyd in Semi-Gloss is Benjamin Moore's flagship product for doors, trim, and cabinets. It is a waterborne alkyd, not a standard latex paint. That distinction matters: the alkyd resin gives you the self-leveling and hardness of an oil based paint, while the waterborne formula means soap-and-water cleanup and lower odor. It brushes, rolls, or sprays to a smooth finish that hardens over time.
For homeowners who prefer a softer sheen on bedroom doors or closet doors, ADVANCE® in Satin provides the same leveling with a subtler look. Coronado® Door, Trim & Cabinet Enamel in Semi-Gloss is a strong alternative at a different price point, delivering a durable, scrubbable finish well suited to high-traffic interior doors and trim.
Is it better to brush or roll paint on a door?
Both tools have a role, and the best paint application approach depends on the door type.
For paneled doors with recessed door panels, horizontal rails, and vertical stiles, an angled brush is essential for the detailed areas. A 2-inch angled brush lets you cut into panel recesses, molding edges, and the hinged edge without leaving paint buildup in the corners. After brushing the panels, switch to a small, high-density foam roller (1/4-inch nap) to roll the flat surfaces, the stiles, and the rails.
For flat slab doors with no panels, a mini foam roller alone can handle the entire door. Roll in vertical strips, maintaining a wet edge to avoid lap marks. The short nap covers flat sections evenly and leaves a smooth finish without orange-peel texture.
The key to avoiding brush strokes on any door is thin coats and enough product on the brush to flow smoothly. Overworking paint that has started to tack up causes visible brush marks. Apply paint in one direction and let the first coat dry fully before adding a second coat.
How to paint interior doors step by step
Once the door is prepped, primed, and laid flat, follow this painting order for paneled doors: start with the recessed panels, then the horizontal rails between the panels, then the vertical stiles on either side, and finish with the edges. Work in the same order for each coat of paint so the overlap pattern stays consistent.
Apply paint in two coats rather than one thick coat. A thick coat sags, shows brush marks, and takes longer to cure. Let the first coat dry fully, then lightly sand with 220-grit sandpaper between coats. Wipe off the sanding dust and apply the second coat in the same order. Allow at least 24 hours before reattaching door hardware and closing the door fully to prevent sticking.
A well-executed interior doors project splits time roughly evenly between prep and painting. That ratio produces a finished result that lasts years.
How to paint a front door
A front door carries extra weight in a project because it faces weather, direct sunlight, and every person who approaches the house. It is one of the fastest ways to boost curb appeal, and the right front door paint color makes a noticeable first impression.
The painting process follows the same steps as an interior doors project: remove door hardware, clean, sand, and prime. Use a high-quality exterior paint or a waterborne alkyd rated for exterior use. Most front door projects require two to three thin coats of paint for full coverage, especially when changing from a lighter shade to a dark color.
Timing matters. Paint early in the day so the door dries as long as possible before closing at night. Avoid door painting in direct sunlight, which traps brush marks and creates uneven sheen. Keep the door open or slightly ajar overnight while the fresh paint cures.
Choosing the right front door paint color is one of the most personal decisions in a painting project. Deep navy shades, classic reds, warm blacks, and bold greens are all strong door colors that complement brick and siding. Browse Benjamin Moore's curated front door colors for proven combinations that deliver curb appeal without guesswork.
Can I just paint over old paint on a door?
It depends on the condition of the old paint. If the existing finish is sound, meaning no peeling, flaking, or heavy chipping, you can paint over it after a thorough cleaning and a light sanding with 220-grit sandpaper to scuff the surface. This gives the new paint a profile to grip.
If the old paint is in poor shape, peeling, or built up from multiple layers, strip it back first. A chemical stripper or heat gun removes old paint effectively. For a previous home built before 1978, test for lead paint before sanding or scraping, and follow EPA RRP Rule guidelines if lead paint is present.
Switching from an oil based paint to a latex paint or waterborne alkyd requires a bonding primer between the layers. Stix® Waterborne Bonding Primer handles that transition cleanly, giving the fresh coat a surface it can lock onto. When in doubt about what is underneath, prime first.

Frequently asked questions
What is the correct way to paint a door?
Remove all hardware first, then clean, sand, and prime the surface. Lay the door flat if possible to prevent drips. Paint the door panels first, then the horizontal rails and vertical stiles, finishing with the edges. Apply two coats with adequate dry time between them. Use a 2-inch angled brush for detailed areas and a 1/4-inch nap foam roller for flat surfaces.
How do you paint a door without leaving brush marks?
Apply paint in thin, even coats and avoid going back over sections that have started to dry. Use a high-quality angled brush with fine bristles and load it properly. A paint conditioner (like Floetrol for latex paint) extends the open time, giving the paint more time to level before it sets. Switching to a mini foam roller on flat sections also reduces visible brush strokes.
How to paint a metal door?
Clean the surface with a degreaser, then lightly sand with 220-grit sandpaper. Apply a bonding primer designed for metal, such as Stix® Waterborne Bonding Primer, and let it cure. Follow with two coats of a waterborne alkyd or acrylic enamel in semi gloss. Metal doors conduct heat and cold, so paint in moderate temperatures and avoid direct sunlight during application.
