Can You Use Acrylic Paint On Metal?

Acrylic paint is trendy due to its versatility. You may use acrylic paint on a variety of surfaces. However, some characters require preparation for the acrylic paint to adhere correctly. Acrylic painting on metal is doable, but it necessitates some preliminary work.

When applying acrylic paint to metal, you can create a range of intriguing projects. Acrylic paint on metal may be challenging, but it is relatively simple. While working with metal surfaces might be scary, acrylic paint can change your metal project with some simple preparation.

Is Acrylic Paint compatible with Metals?

Acrylic is a versatile paint that you may use on various surfaces. You may use acrylic paints on metal for several tasks. Painting metal requires some prior preparation, regardless of which job you tackle first. Depending on the type of metal you choose, the methods for priming and sealing the paint into the metal will differ.

Many acrylic paints for external things, for example, come in spray cans and have a sealer. To put it another way, they don’t expect you to protect the paint. Old metal goods with corrosion, on the other hand, may require a specific priming coat.

Acrylic Paint for Metals:

There are three options in acrylic paint for metal projects:

Oil-based paints: Oil paints are excellent for painting exterior metal surfaces without priming, but they are significantly more expensive than water-based paints.

Water-based paint: Water-based Acrylic paints are perfect for painting interior metal surfaces. They dry quicker than other solutions, but they still need to be primed and sealed.

Spray paint: Spray paint is suitable for novices and works well on metal, but it does not last long as other paint alternatives.

Most metal items may be painted using regular acrylic paint. Although acrylic paint isn’t required for metal, the sealer and primer must match the color of the paint.

Acrylic paints are available in oil and water bases, spray cans, and standard containers. Some are designed for use in the outdoors or with metal. Even severe heat isn’t a problem for certain types. Check the paint bottle for instructions on how to use it properly.

Priming metal surface

It would help if you used a primer for this technique to operate correctly. Choose an acrylic paint primer that is very suitable. If you use the improper primer, you will not get the effects you want.

Pick a primer that’ll work with the paint you will use. Spray cans, buckets, and cans are among the many containers available for primers. Choosing a universal bottle that includes both the color and the primer is preferable. Choosing a multipurpose bottle for both the paint and the primer is preferable.

Apply two coats of priming with a brush, waiting till the application is dried before adding the second. You can start painting when your material has dried thoroughly.

When working with a metal surface, it’s best to apply two coats of primer. Your character will be shielded from excessive wear and chemical exposure with two coats of primer. A two-coat primer also improves the adhesion of your paint to the surface.

Is primer necessary for metal surfaces?

While you may apply oil paint directly on metal, acrylic paints usually require the metal to be primed first. Because of the moisture in the paint, you should first use primer on the metal surface or risk rotting it over time.

Acrylic paint is porous and may include water-resistant components, although it is not waterproof. Moisture erodes the color, causing rust issues. Primer also ensures that the paint adheres adequately to the smooth surface. Traditional metals with exposed surfaces are the only metal surfaces that require special attention.

How to Seal Acrylics

Because acrylic paint isn’t waterproof, you’ll need to seal the metal after painting it. You can use acrylic paints in an aerosol instead of spray paint if you don’t want to use spray cans. If you choose exterior acrylic paint, you won’t have to seal the surface afterward.

However, regular acrylic paint will need an acrylic spray sealer to protect your work on an indoor job. Most sealers are available as a spray polish or as a paint-on sealer. Allow at least two days for the product to dry completely before utilizing it.

How to Paint Metal with Acrylic

Before you paint with acrylics, prepare your work area. Safety requirements call for ventilation when you’re painting. You’ll also want to protect your surroundings by laying down a drop cloth or newspaper. Keep a cleaning rag nearby to wipe away any spills.

Protect yourself with gloves and wear an apron or protective clothing as well. The U.S. Consumer Product Safety Commission warns that some of the ingredients in solvent-based acrylics are toxic to inhale. Wear a mask and work somewhere with proper ventilation, like outside or in a garage. If you have to paint inside, open a window.

Another safety concern is the metal itself. If there is a chance the item you want to paint could contain lead, you need to wear protective clothing and take precautions. The Centers for Disease Control and Prevention (C.D.C.) says the information is absorbed into the human body whether you breathe, swallow, or drink it, causing adverse health effects.

Using acrylic paint on metal may seem complicated, but the process is less intimidating than it looks. Use these step-by-step instructions to transform your metal project.

Get your tools ready

Start by collecting the materials you need. First, prepare your work area. Clean any dust or debris away and protect the surface. We’ll look at preparing the metal’s surface next.

Collect the following:

Drop cloth

Preparing the area, you’ll be working in is essential for keeping dust, dirt, and paint out of your workspace and belongings. If the space is small, place a tiny bit of plastic or a similar insulating layer between your craft and the surface you’re working on. Plastic or cotton drop cloths, such as those illustrated below, are an effective solution to cover your space or valuables for more significant regions.


Cleaning cloths are helpful in a few distinct stages of this procedure. Keeping a few available will aid in the smooth running of your job. Microfiber material is an excellent material for trapping debris from your project, which helps achieve a smooth finish.

Painters tape

While using painter’s tape to keep paint from getting on particular parts of your craft may seem like a waste of time, it will be well worth the extra effort. you may use painter’s tape to cover areas that you do not need to get paint on while painting the surrounding areas. Painter tape is designed to leave no sticky residue behind when removed, preventing harm to surfaces.


Cleaning dust and dirt from your metal before painting is essential for the prep work. While soap and water may suffice for little chores or surfaces with no tenacious residue, other projects will necessitate the use of a cleaning solution. After scrubbing and sanding, cleaning up dust and debris from your craft should be done with a rag dipped in warm soapy water.


Gloves are helpful when working on a metal project since they protect your skin from dust and paint. Keep a package of disposable gloves accessible to swap out between tasks during your project.

Wire brush and Sandpaper

A wire brush features stiff wire bristles that are strong enough to scrub off old paint, corrosion, and other debris from your surface. Meetings of various sizes, such as the tiny wire brushes shown below, may be beneficial for cleaning hard-to-reach places on your metal object. 150 grit sandpaper is also used for this purpose.


For a few reasons, primer is required on your scraped metal item. It coats a metal surface with a protective coating that covers previous rust and prevents the area from rotting in the future. It also serves as a coherent substrate for the paint, attracting and holding it. Spray primer, such as the one seen below, is a practical alternative to traditional priming paint since it uniformly and quickly coats your surface.


If acrylic spray paint isn’t suitable for your craft, you could use a paintbrush to paint it. To reach difficult-to-reach areas, many sizes of brush may be required.


Sealers are used to preserve your final dry object from moisture and Damage while also giving it a polished appearance.

Please remember that the acrylic paint you buy may differ depending on your project. Acrylic spray paints are easy to use and give a smooth, uniform finish. There is no need for a sealer when using outside paint because the sealer is already included in the color. If you’re using regular acrylic paint and want to add extra protection, a sealer like the one depicted below can help. If you’re painting an outside metal object, you’ll need exterior or outdoor paint.

Peel off paint and rust

Once you have all of the supplies, scrape the whole metal surface you want to lament using a wire brush. The brush’s firm bristles come in various sizes, so they should be able to reach any hard-to-reach places. Clean the whole metal surface using a scrubbing pad. As you work, clean the particles with a wet towel.

Scrub the Metal

After completely covering the metal surface with the metal brush, use the fine-grit sandpaper to smooth it out. If you’ve worked with power tools before, seek a wire brush extension to quickly remove paint from an extensive surface.

You may also use a cordless drill instead of the wire brush and Sandpaper. Any leftover rust or paint is removed with 150-grit Sandpaper.

Clean the Metal

Clean the metal after that. The material’s surface usually holds oils that you won’t detect just by glancing at it. You should use soap and water to clean this as thoroughly as possible. If the metal remains unclean, you can use a cleaning solution to dissolve stubborn residue, grease, or dust particles.

Some individuals prefer to use alcohol swabs instead of a towel and soapy water to clean their metal. If you don’t clean the metal thoroughly enough, the paint finish may appear bad or peel off rapidly.
Even if the metal looks clean to the human eye, never omit this step. Galvanized metal, in particular, needs a thorough cleaning. You must thoroughly clean the oils with a detergent solution for new galvanized metal.

Use Primers

Check to see if your primer is suitable for acrylic paint and metals. Start applying the primer to the surface after you’re confident it’s safe. The zinc-chromate should be used as a preliminary layer to help the primer adhere better. Depending on the primer you choose, the steps you do may differ. The best primers for metal are those developed specifically for metal. A standard oil-based primer will suffice. Two coatings safeguard the metal from oxidation, corrosion, and Damage caused by prolonged contact with the environment. Apply two even layers of primer, allowing for at least 2 hours of drying time between applications.

Start Painting

Apply the paint once your metal has been primed and dried thoroughly. Acrylic paint is also available as a spray or a liquid. Regardless of the option you pick, apply at least two equal layers of paint and let them dry completely between applications. Regular acrylic paint works nicely for painting interior things. It’s possible to apply up to 7 thin coats of spray paint.

Coat the metal with a paintbrush or spray it with a can, following the recommendations on the container. This may result in a sloppy, thick application of paint. If you’re using more than one color, tape off the parts and allow the first one to dry before proceeding.

You may also put a logo or letters to a metal object by painting the first layer one color and then covering it with another. You can use painter’s tape to mark off any surface areas where you would not want to paint them paint. If you’re using acrylic spray paint, read the label to determine if it has to be sealed afterward. If you’re using a paintbrush, take caution not to overfill the bristles.

Apply sealer

It is not usually necessary to seal acrylic paint on metal. Sprays and liquids are used as sealants for painted metal. In addition, the sealer gives longer-lasting protection. A primer is required for conventional metals or those constantly exposed to the environment. The majority of possibilities are clear, although some may have stains of various hues. Apply the sealer according to the manufacturer’s instructions. There are many different types of sealants.

Look for a sealer that’s appropriate for the surface you’re painting. Whether or not your metal needs a sealer, you may apply it to give your item a glossy appearance.

Ensure the metal is clear of dirt, oil, grease, and corrosion before applying the sealant. Exterior paints and certain spray acrylic paints, on the other hand, already contain a sealer, so there’s no need to re-seal them.

Can Acrylic Paint endure Water-damage?

While acrylic paint is generally long-lasting and won’t fade or decompose without much work, it isn’t waterproof, especially if it’s put on a slippery surface like metal and left outside regularly. Apply a water-resistant sealer over the paint to guarantee that your painted product can endure rainfall, snowfall, or another calamity.

Brush vs. Spray Painting on metals

Acrylic paint may be applied to metal using a paintbrush, a roller, or a spray can, which is excellent news. You can use a spray to paint a metal table completely white, but you’ll need a brush if you want to add carefully painted features to the surface afterward.

Some companies sell an acrylic spray designed exclusively to be used on metallic surfaces and is weatherproof. If you’re working on a big project that requires a lot of paint on a metal surface, a spray like this is the way to go.

Can acrylic paint be washed off the metallic surface?

You might think you can easily wash acrylic paint off metal if you got it wrong or wish to erase it. Acetone and varnish remover are two great products for this purpose.

You have a couple of possibilities for different home-based solutions. A carefully designed remover would be the safest approach to removing acrylic paint from any metallic surface. A good paint remover is better since it removes dried paint without causing Damage to the object.


So, can acrylic paint be used on metal? It’s easy to become perplexed by the laws around the paint kind you employ for your project. However, it is well worth the time and effort to learn how to prepare correctly, paint, and protect acrylic paint on metal.Your newly painted items will undoubtedly last for many years. At first glance, metal projects appear to be a daunting endeavor. Following a few easy steps to prepare correctly and complete your project will help streamline the process and ensure that it is a success.
