If you want some good quality paint brushes, Wooster and purdy brush can be an excellent choice to paint your metal door.
Foam Paint Roller
Rollers are used to paint the flat areas fast, where the paintbrush can’t give a smooth finish.

Choose The Right Paint
What type of paints you are going to use to paint the metal door will make all the difference. Water-based latex paints can be used on both interior and exterior doors. They adhere to the surface well, dry fast and prevent rust.

How To Paint A Metal Door Without Brush Marks (11-steps Complete Guide)
Do you want to paint your metal door smartly? Beginners or experts follow our simple recommendations to paint a door without vertical or horizontal brush marks. Let’s go into the details.
1. Done The Necessary Prep Work
Without a clean and smooth surface, the paint will not adhere properly. So, before starting the paint job on the metal surface, make sure you have done all the necessary preparation.
Take a 220 grit sponge sandpaper to settle down rough areas of the door. It will be more accessible to sand angles and allow you to reach nooks and crannies of the door.
Either you paint the interior or exterior door, make sure you power wash it to clean dirt and debris. Wipe the door using a microfiber towel. If you do that, it will ensure maximum paint adhesion.
You may find small holes or cracks, which you need to fix before painting. Apply caulk or spackle in the holes and cracks. When they dry, lightly sand the area to level up with the surface.
2. Take Off The Door, Handles, And Door Hardware
Removing the entire door from its hinges is your choice. If you hire a professional painter, they will quickly remove it for painting. Another reason is that you can remove the door if you use a sprayer to get the paint done. A sprayer is a quick process of painting on both sides of a door. If you do not remove it from the hinges, the paint may spread out the door.
You can also finish painting without removing it from the hinges. You may take off the handles and other door hardware or tape them carefully with painter’s tape. Complete it before the sanding, and it will protect the metal parts from cosmetic damage.
3. Sand Old Brush Marks
Painting on your previously painted door needs minor work to be done. You may find some imperfections (Brush Marks And Blemish) on it, which must be sanded down properly.
Take a 100-120 grit coarse sandpaper, slightly run it over the old brush marks and inconsistent areas. It will make the surface flat and smooth. Avoid using too much pressure during sanding. Use a vacuum to clean all sanding dust.
4. Apply The Primer
Painting over a new door requires a fresh coat of primer. It will ensure great durability for a long time. Use a brush to apply primer to the edges and inside parts. A small roller helps you to paint outer flat surfaces.
When the primer is completely dry, sand it in between coats to get a smooth paint job.
5. Avoid Brushes On Flat Surfaces
If you want to paint like professionals, avoid using a brush to paint on flat surfaces. Using a brush can leave brush marks on your door. But a high-quality foam roller can end up painting without leaving any marks and bumps.
Not only that, you are able to cover a wide area in a short period of time.
6. Follow The Grain Direction
Door slabs have different parts of grain directions that you have to follow when painting. One of the best ways to avoid brush marks is painting flowing the grain direction. Use a brush instead of a foam roller. This will allow you to get off from unsightly brush marks.
7. Improve Paint Leveling
Brush marks most of the time occur due to poor paint leveling. A common cause of poor paint leveling is wet and unsmooth paint finish.
Add conditioner (floetrol) to paint instead of water. This will turn the paint thin and give a long and smooth coverage. Ensure the temperature isn’t over 90°F. High temperatures will dry the paint quickly and ruin the paint leveling. Sometimes high-quality paint provides proper leveling from the beginning.
8. Apply The First Coat Of Paint
It’s crucial to select the right kind of paint for avoiding brush marks. Semi-gloss latex paints will be a top choice on this occasion. They give a smooth paint job for both exterior and interior doors. You can use them without getting in any trouble. Also, there are few popular metal paints available to use on metal doors.
Take your desired metal paint color, apply the first coat. Let it dry for a day before applying the second coat.
9. Lightly Sand After Every Coat
It’s possible to achieve a smooth topcoat finish if you sand after every coat of paint. Lightly sanding the brush marks and other imperfections areas of the first coat. Remember, don’t rub too hard, just make sure the paint looks smoother than before.
10. Apply The Second Coat/Topcoat And Let Dry

Load your brush with a small amount of paint and dab the paint on those areas. Next, let the paint dry for 24 hours.
