Metal paint not only decorates the metal, but also protects it, especially when it is iron or steel, which are more exposed to the risk of corrosion. However, you should be aware that there are many different types of metal paints, depending on the metal concerned, but also on the desired effect.
Finally, it is important to know that the application of a metal paint follows a particular method.
Best Paint For Metal You Can Use
You need the right type of metal, and you need to know what kind of paint will work on a given metal.
Here are the top 3 paints you can use for metal:
- Majic PAINTS Interior/Exterior Satin Paint – paint for metal, wood and more

Types of Paint for Metal
Metal surfaces of any kind is not very adhesive. Any type of paint doesn’t suit it. Acrylic-type paints are not suitable for metals. It is better to use oil-based paints such as glycerol paint or epoxy paint. Usually used as a floor covering, polyurethane lacquers can also be used to cover metal.
Caution: All oil-based paints are highly toxic and should always be used in a well-ventilated room or outdoors (ask for free quotes from professionals for your metal painting work).
Each Metal Has Its Own Special Paint
Not all metal paints are suitable for all metals. Indeed, aluminum does not have the same characteristics as steel or iron. The same applies to zinc or bronze.
Iron Paint, Treatment against Rust
An iron paint is mainly composed of anti-corrosion agents. It is more of a treatment with the aim of protecting the iron permanently, especially when the iron part is outdoors. However, other non-iron paints can be used, provided they are combined with one or two coats of anti-rust paint.
Metal Paint for Aluminum
Aluminum is a particularly smooth metal with little grip. It is therefore advisable to use a metal paint specially designed for aluminum. It will be a more viscous paint that adheres more easily and quickly to a smooth surface.
To ensure that the paint will hold on aluminum, it is often recommended to lightly sand the aluminum before applying the paint. This may, of course, affect the characteristics of the aluminum part. Another solution is to apply an undercoat to provide adhesion.
Note: Contrary to popular belief, aluminum can show traces of oxidation. Before applying the paint, therefore, make sure to treat it with a rust converter product.
Paint for Special Metals
Zinc, cast iron, bronze, these are metals that we are less used to painting. Their beauty often lies in their patina. Nevertheless, it is still possible to paint them. Iron paint is suitable for them but there are special paints for zinc, cast iron or bronze which are more in keeping with their characteristics and do not risk distorting them.
Tip: to paint special metals, use special raw metal varnishes instead.

Application Tips for Metal Paint
To obtain the desired effect, it is important to choose the finish of the paint you are going to apply. But the result depends mainly on the proper preparation of the surface. Whatever the type of metal, two coats of paint are always recommended.
Preparation Prior To the Application of Metal Paint
The preparation consists of cleaning the metal surface. Use soapy water for this purpose. In the case of rust marks, it may be necessary to sand lightly. Be sure to use a fine sanding paper for aluminum type metals. Otherwise, white vinegar can be used to remove small stains. Then allow the surface to dry before applying the paint to the metal.
Apply the Metal Paint in Two Coats
For iron, it is imperative to provide a coat of anti-rust if the paint does not contain any. For other metals, two coats are essential: one for protection and treatment of the metal and the other for finishing. You can use a roller or a brush, but there are also paint sprays that are easier to use but more expensive.
