Compared to most materials and surfaces, metal is one of the toughest surfaces to paint on since it involves a lot of techniques and preparations. Keeping this in mind, you need to dedicate some time to preparing the surface properly before moving on to the painting process.
Firstly, we recommend removing any rust from the metal surface since it will hamper the adhesion of the acrylic paint. You can remove the rust by using fine-grit sandpaper or a wire brush to eliminate the traces of rust from the metal surface. In addition, you should also remove any old paint present on the metal surface; otherwise, it will result in an uneven texture.
While sanding the surface, make sure to even it out thoroughly and wipe the dust with a damp cloth. Besides this, you can use alcohol wipes to clean the metal surface you have been preparing all this while. Once you have completed this process, you will need to coat the surface with a primer.
Nowadays, most brands manufacture unique primers that can work efficiently on all types of metal surfaces. However, some acrylic paints already have primer added in the main formulation, making it cheaper and ideal for any metal project.
Moving on, the final step will require you to seal the surface using a sealant. This allows the paint to survive any harsh weather conditions. On that note, some acrylic paints are developed to suit outdoor metal surfaces such as gates, railings, outdoor furniture, and many more.
What Types Of Paint Can You Use On Metal?
When it comes to painting metal surfaces, there are three types of paints that are most commonly used to get the job done. Here are the top three highly recommended paints for metal painting.
A. Oil Paint
Oil paints are well known for being an ideal option for outdoor and indoor use. However, most artists prefer to use oil paint since it doesn’t require any additional coat of primer for metal surfaces. The oil present in the formulation acts like a primer to keep the paint durable for a long period.
Although it might seem like a convenient option, oil paints usually cost more than regular acrylic paints.
B. Spray Paint
Spray paints are an excellent option to go for when painting metal surfaces, especially if you are a beginner. You don’t require any prior techniques or skills since the paint can be applied through the spray can directly. But, when it comes to longevity, this paint falls short compared to other paint options on the market.
C. Acrylic Paint
Lastly, acrylic paints are water-based paints that are ideal for indoor metal surfaces. This paint is well known for having a quick-drying process, but you must prime the metal surface before applying the acrylic paint.
How To Make Ordinary Acrylic Paint Waterproof?
Generally, acrylic paints are fairly durable and versatile as they can be used on all types of surfaces without any difficulty. Besides that, they can last longer since they require a lot of effort to break down. As such, acrylic paints tend to be waterproof, but you will require to take a few precautions in some situations.
For instance, if you plan to do an outdoor acrylic paint project, we highly recommend applying a water-resistant sealant over the acrylic-painted metal surface. This gives the painting an additional layer of protection against snow and rain. It can also be used for customizing furniture and making them waterproof.
Which Is The Best Way To Apply Acrylic Paint On Metal?
When it comes to acrylic paints, you can use several different forms of application to apply them onto a metal surface. Some of the most common tools for applying acrylic paints are spray cans, rollers, and brushes. This allows the painters to be extremely flexible as they can repaint over an acrylic-painted metal project.
While some may prefer to use a brush or roller, others might use spray cans as a convenient application method. However, there are cases where you might need to use both spray cans as well as brushes to achieve the required results.
For example, you can use a spray can to paint an entire table in one uniform color. On the other hand, brushes can be used to add intricate designs to make them look more stylish. Some brands even manufacture acrylic sprays to be extremely durable, so they are suitable for painting outdoor metal surfaces.
Besides this, spray cans are ideal for large-scale acrylic paint projects, while brushes and rollers can be used for small-scale and medium-scale ones.
Can Acrylic Paint Be Used On Metal Without A Primer?
No! When it comes to acrylic paints, you need to use a primer on the entire metal surface first since it prevents moisture and rust. In fact, acrylic paints contain water as a part of the main formulation since they are water-based paints. Therefore, excess exposure to water will eat up the paint and cause the metal surface to rust.
On that note, a primer’s main purpose is to prevent moisture from damaging the metal surface; however, not all surfaces need a primer. For instance, stainless steel doesn’t require a primer since it is manufactured to prevent rust and oxidation from occurring. Primers can also be used to provide better adhesion for acrylic paint.
What Is The Best Primer For Metal Surfaces?
While working on a metal surface, it is important to prime it since it helps give the paint a better grip. You can use liquid or spray primers on a metal surface as long as you follow the required instructions given by the brand.
You will need to shake the spray cans for at least one minute before applying the primer onto the surface. Also, you should make sure that you are using oil-based primers, as they are extremely compatible with acrylic paints and help maintain durability.
Usually, it is recommended to apply at least two coats of primer. You should give each coat a minimum of two hours to dry before applying another layer of primer. These coats will protect painted metal surfaces from corrosion, damage, or oxidation and help the paint last longer.
Additionally, if a metal surface is covered in rust, you should apply a zinc-chromate primer before using any regular primer. This step is important since the zinc-chromate primer will provide better protection from rust.
Can Acrylic Paint Be Washed Off From Metal Surfaces?
There can be instances where you will need to remove the paint you have applied on the metal surface. In this type of situation, you can wash off the acrylic paint from the metal surface, but you will require the right tool to get the job done.
The easiest and safest way to wash off acrylic paint is by using a remover specially formulated for all types of acrylic paints. Similarly, you can use household options such as isopropyl alcohol to remove the paint; however, we recommend wearing some protective clothes.

How Can You Prevent Acrylic Paint From Chipping Off?
Ideally, we recommend applying an additional layer of topcoat on the metal surface if you are planning to use the surface quite often. Regularly using a metal object or surface can cause the paint to chip off easily; therefore, an extra final coat of acrylic paint will give you better adhesion and protection.
You can apply a polyacrylic coat through a paint sprayer to give the metal surface an even finish.
What Are The Best Brushes For Acrylic Painting?
When it comes to acrylic painting, round brushes are well-known for coming in different sizes and can be used for both large scales as well as small-scale projects. Apart from this, you can purchase an angled brush since it can add a unique depth to the painting.
Can You Paint A Metal Surface Without A Primer?
Normally, you will have to apply a coat of primer on the metal surface before using any acrylic paint. The main reason is that the elements in the metal can react with acrylic paints, and this will cause the paint to oxidize over time.
For instance, aluminum products usually don’t hold acrylic paints well, so you will need to seal the surface with a primer before working on them.
How Do You Clean Your Acrylic Painting?
The easiest way to clean acrylic painting is by using water and soap. After the painting has completely dried and cured, you can clean the acrylic painting by using the detergent solution gently.
First, wet the surface with a wet cloth and apply soap so that it will remove any residue from the surface. Then you should use a clean cloth to remove the remaining soap and let the surface dry completely before using it again.
How Long Do Acrylic Paints Last?
There are several factors that can influence the longevity of acrylic paints. For instance, acrylic paints can lose their durability in moist weather conditions or if the surfaces are not primed properly. Apart from this, excessive use of the metal surface can chip out the paint over time.
Nevertheless, acrylic paint can last for a few days to a few years, depending on the type of surface you paint on and how you preserve the painting.
