How to Paint a Metal Front Door

The front door is often the focal point of a home’s exterior. A freshly painted metal front door can help enhance your home’s curb appeal and create a welcoming first impression. While metal front doors are durable, the paint can chip and fade over time from exposure to the elements. Painting a metal front door requires proper preparation and technique to achieve beautiful, long-lasting results. Follow this step-by-step guide to learn how to properly prep, prime, and paint a metal front door.

Choose the Right Paint

When selecting paint for a metal front door, there are a few important considerations:

Type of Paint

Oil-based enamel paints provide the most durable and glossy finish on metal front doors. The hard, protective surface resists chipping, scratching, and fading better than latex paints. Alkyd enamel paint is another good oil-based choice.

Latex paint can also be used on metal doors, but the finish may not hold up as well over time compared to oil-based paints. Latex enamel paints formulated specifically for metals and exterior use provide better durability than standard latex paint.

Rust-inhibitive primers containing anti-corrosive properties help prevent rust from developing under the new paint. Opt for an oil-based rust-inhibitive primer for best results.


Semi-gloss or high-gloss sheens are ideal for front doors, as they are easier to clean and more durable than flat finishes. Glossy enamels also enhance the beautiful, bold look of a front door.


With so many colors to choose from, select a shade that complements your home’s exterior color scheme. Darker, bolder colors like black, navy, red, and green are popular front door colors. Softer neutral tones are also welcoming on an entryway.


Invest in top-quality exterior grade paints and primers from reputable brands. This ensures maximum durability against weathering and prevents early cracking or peeling.

Prep the Metal Surface

Proper prep is crucial for getting paint to adhere correctly to metal. Follow these steps:


Use a degreasing cleaner or solvent to remove any dirt, oil, grease, and mildew. Rinse thoroughly.


Lightly sand the metal door with 220-grit sandpaper to rough up and degloss the surface. This helps the paint adhere better.

Remove rust

Eliminate any rust spots using sandpaper, steel wool, or a wire brush. Sand down to the bare metal.


Apply a rust-inhibitive metal primer to all surfaces. This provides corrosion protection and improves topcoat adhesion. Allow primer to fully dry per manufacturer’s instructions before painting.


Caulk around all seams, corners, and hardware using a high-quality exterior caulk. This prevents moisture from getting under the paint.

Tape off

Tape off door handles, hinges, windows, and hardware using painter’s tape. This keeps splatters and brushstrokes off these surfaces.

Paint the Front Door

Follow these tips when painting the primed metal:

Work in thin coats

Apply paint in multiple thin, even coats rather than one thick coat. Thin coats create a smoother finish.

Remember all sides

Paint the door on both exterior and interior sides for full protection.

Follow dry times

Allow proper dry time between coats as indicated on the paint can. Rushing the process can ruin the paint job.

Lay paint smoothly

Use a high-quality nylon or polyester brush, or a microfiber roller, to smoothly apply the paint without leaving brush marks.

Maintain a wet edge

Maintain a wet edge as you paint by brushing back into edges before moving onto new areas. This prevents lap marks.

Watch the weather

Avoid painting in direct sunlight or if rain is expected. Heat and moisture can ruin fresh paint.

Work top to bottom

Paint from the top of the door down to avoid drips running through fresh paint.

Apply multiple coats

For maximum durability and vibrant color, apply two to three coats of high-quality exterior grade paint.

Tips for a Flawless Paint Job

Follow these pro tips to ensure your painted metal door looks beautiful and lasts for years:

  • Lightly sand between coats using fine (320-400 grit) sandpaper for an ultra-smooth finish.
  • When spraying paint, keep the can 10-12 inches from the surface and apply light, even coats.
  • Use painter’s tape with delicate surfaces for the cleanest paint lines. Remove tape immediately after painting before the paint dries.
  • Paint on a dry, low humidity day with temperatures between 50-90°F for ideal paint drying conditions.
  • Allow the full recommended dry time between coats. 48 hours is ideal in cooler temperatures.
  • Use a small brush to neatly “cut in” around hinges, hardware, windows etc. before rolling larger areas.
  • To avoid brush marks, keep a wet edge and maintain a steady painting pace.
  • Coat door edges and the side jambs so all exposed metal is covered.
  • Properly clean brushes after use in the appropriate solvent.

Following proper metal door painting techniques will help the paint cling tightly and deliver that fresh painted look for years of welcoming arrivals to your home. With a little time and effort, you can achieve stunning results!

Frequently Asked Questions About Painting Metal Front Doors

Painting your metal front door can enhance curb appeal while protecting it from the elements. Here are some common questions about prepping and painting metal entry doors:

Should I remove the door to paint it?

  • You don’t necessarily need to remove the door for painting. It’s often easier to paint it in place. Just tape off hinges, hardware, and glass to protect these surfaces.

How long does it take to paint a metal door?

  • Plan on a full day for proper prep, priming, painting, and dry time between coats. The project could take 2-3 days depending on drying time needed between steps.

What kind of primer should I use on a metal door?

  • For best corrosion resistance, use an oil-based or alkyd rust-inhibitive primer specifically made for metal. Allow for full drying time before painting.

How many coats of paint should I apply?

  • For long-lasting color and protection, apply 2-3 coats of a high-quality exterior enamel paint. Allow proper dry time between coats.

Should I use spray paint or brush paint?

  • High-quality brush painting generally provides the most even coverage and professional looking finish. Spray painting requires less brush skill but doesn’t provide the same level of control.

How do I get paint drips out of freshly painted metal?

  • Carefully scrape off fresh drips with a plastic putty knife, then touch up with paint. Avoid drips by painting top-to-bottom and maintaining a wet edge.

What kind of caulk should I use on a metal door?

  • Use a high-quality, flexible exterior-grade caulk designed to last. Make sure the surface is clean before applying.

Should I paint the door’s interior side too?

  • Yes, for maximum protection paint the interior side with the same high-quality exterior enamel paint used on the outside.

Can I paint over rust?

  • No, rust should be removed by sanding, wire brushing or other means before priming and painting metal surfaces.

Following the proper prep work, priming, painting method, and dry times will help ensure your metal front door paint job protects and beautifies your entryway for years to come.
