Why Use a Metal Door?
In this article, we will look at the best types of paints for metal as well as how to paint a metal door. But first, let us consider the metal door. Metal doors are very popular for public buildings as well as commercial and industrial spaces. They are usually paired with a metal frame and created hollow to reduce weight. What follows are some reasons why you would want to repaint your metal door rather than discarding it for a wooden or aluminum alternative.
Unpainted stainless steel doors can add a chic, industrial look to any space. It is also easy to clean. There are many different colors and shades of paint available for metal. There are also quite a few different types of finishes to choose from. Metal doors can be customized fairly easily. Mail slots can be installed as well as weather strips.
Customizing doors in this way may require the assistance of a professional unless you have had some experience with power tools.
Along with resisting forceful impact, metal doors also stand up to the elements and resist extreme hot and cold temperatures as well as frost, moisture, and humidity. Stainless steel doors will resist corrosion even without a coat of paint. However, mild steel doors will require high-quality exterior metal paint to seal them off from corrosive environments such as coastal areas.
Metal doors offer an almost Fort Knox-like security to your building. This is because metal is naturally stronger than the toughest wooden door. You may think that a hollow metal door will not stand up to punishment; however, a hollow metal door absorbs far more impact than it would if it were solid.
A solid door will transfer the shock of this hypothetical impact to the edges which could damage the frame.
Considering all the benefits of having a metal door installed on your property you will find that hollow metal doors are far more affordable than you may think. Consider purchasing a metal door as an investment in your security.
Types of Paint for Metal
With all the types of paints for metal, you may be wondering which one is the best paint for garage doors or which one is best for interior metal doors. In this section, we will take a look at the different types of paints for metal to help you get a better understanding of what to expect from different metal door paints. It is important to note that you will get the best results from your paint by first applying a primer to the metal. This will ensure proper adhesion of your paint as well as increase the durability of your metal doors paint.
Water-Based Paint for Metal Doors
Latex or water-based paints are very convenient as they tend to dry faster than oil-based paints. Water-based paints are also much more pleasant to work with as they tend to have a low odor in comparison to oil-based paints and cleanup does not require any solvents, water will do the job just fine.
While applying a primer is always recommended it is especially the case when it comes to water-based paint but even then, water-based paints are not as durable as oil-based paints.
Water-based paints do not stand up to the rigors of use as well as epoxy or oil-based paints. However water-based paint is generally more affordable than oil-based paint and once it has dried it is very easy to clean.
Oil-Based Metal Door Paint
While there are specialized door paints on the market, most of these will be oil-based, and for good reason. Oil-based paints are tough and do not chip or scratch easily. These types of paint come in a wide variety of colors and finishes from flat and matte to high gloss and semi-gloss. Oil-based paints can smell bad as they tend to contain chemicals like solvents. Working with these paints requires you to do so in a well-ventilated environment and it is also advised that you don a respirator.
Oil-based paint comes in many formulations that can be rolled, brushed, or sprayed on. Choosing to use a can of spray paint for a metal door is less than ideal as spray cans are more suited to smaller projects. Generally speaking, oil-based paints take longer to dry than other paints but there are quick-dry formulas to look out for. While some paints on the market are specifically formulated for metal doors, oil paints are a good option too because of their durability.
Epoxy Paint for Metal Doors
Epoxy is tough and it is a great choice for painting a metal door. These types of paints are usually used in industrial settings such as the automotive industry as well as the pressure vessel manufacturing sector. The one inconvenient part of working with epoxy paints is that it requires you to manually mix a hardener with the resin paint.
This hardener acts as a catalyst that sets the curing process in motion.
Depending on how much you put in can affect how rapidly your paint begins to cure, which can make things tricky if you put too much hardener in and it begins to set mid-project! The best part of using this paint when painting a metal door is that it is extremely hard-wearing. It even resists solvents! Epoxy paint resists chipping as well as cracking and can withstand very high temperatures.

- Small paintbrush
- Painters tape
- Drop cloth
- Tools (for removing hinges and fittings)
- Sawhorse (optional)
- Paint stripper (optional)
- Nitrile gloves
- Tack cloth or lint-free cloth
Choosing to take a bit of time to prepare before you get to paint a metal door can make the difference between a quality-looking finish and making a botch of things. Use the list of supplies above as a checklist to be sure you have everything you need.
Removing the door from the door frame can make the job a lot easier and so will remove all the fittings such as the doorknob, letter trap, and peephole. If you can not remove the door for some reason or another, you can paint the door while on its hinges just be aware that there is a greater chance of drips forming when the door is vertical. If you managed to remove the door and the fittings, place the door on a sawhorse or across trestle legs. Use a drop cloth to protect the floor and anything else you do not want to mess paint on.
Make sure to work in a well-ventilated area and be aware that it is advised that you wear a respirator while stripping paint, sanding, and painting.
Cleaning and Sanding
First, remove the grease and grime from the surface of the door using a commercial degreaser. This will increase the bond of the paint. Once you have degreased the door and you are confident that the door is clean, it is time to lightly sand the surface. Use 320 or 400 grit sandpaper to create a decent surface profile for the paint to bite into. You can paint over existing paint but it is a good idea to use sandpaper and a putty knife to remove any chipping and flaking paint. Stripping old paint using a chemical stripper is also an option when painting a metal door.
Chemical paint strippers are toxic and should be used with caution. If you choose to strip the old paint from the metal door, apply the paint stripper and allow it to sit. The old paint should begin to bubble and lift from the metal. Use a putty knife or scraper to remove the paint and use steel wool on more stubborn areas. Make sure to wear latex gloves and safety goggles. Give the metal door a good rinse with water to make sure the chemical stripper is completely washed away. Any residue left behind can affect the bond of the paint negatively.
Once the metal door is dry, proceed with light sanding. Always refer to the manufacturer’s safety precautions and instructions for use.
Priming the Steel
Applying a primer increases the adhesion of the paint to the steel which increases the durability and it also makes for a more even coat of paint. If you are using a combination of paint that has a built-in primer then you can skip this step. If your paint is dark use a gray primer and if your paint is light in color use a white primer. This will prevent the chances of your primer showing through your topcoat. Before you begin applying the primer to your metal door make sure that it is free from dust, grit, and debris.
Tack cloth does a great job at this. Alternatively, you can use a lint-free cloth. At this point, you will want to mask any areas with painter’s tape that you do not want to paint. This includes fittings that you could not remove. If the door you are working with has recessed panels use a brush to cut these in with a paintbrush. Once you have done this proceed to apply the primer using a short-nap roller or a foam roller.
Let the primer dry for the time suggested by the manufacturer and then apply a second coat if you feel it is necessary.
Painting a Metal Door
Paint the door with your metal door paint. First, cut in any recessed door panels and other areas that may be tricky to reach with a roller. Once you have done this, continue applying the metal door paint with the roller. To achieve the best finish, aim to apply multiple coats of paint while allowing the paint to dry between each coat. This is a far better strategy than applying a single thick coat. If you are working on a sawhorse you will have to flip the door over to address the other side.
Just make sure that the paint completely dries before you do so to avoid damaging the paint. If you have chosen to paint the door while it is still on the hinge in the frame, you may want to plan to apply one coat of metal door paint, allow it to dry, and then proceed with the second coat the following day. By doing this you will be able to close your door in the evening instead of leaving it open all night. Once the metal door paint has completely cured it is time to put the hinges, doorknobs, and the other fittings back onto the door.
Reassembling the door prematurely can risk damaging your fresh coat of paint. Rather be safe than sorry.
