Tutorial Guide on Painting Metal with Acrylic Paint
Before you begin the process of painting, ensure that you have read and understood the manufacturer’s instructions on the type of paint you want to use. This will enlighten you on how you should prepare your surfaces first before applying the paint. The following is a short tutorial guide on how you can apply acrylic paint to metal.
How to Prepare the Metal Surface
- Always clean your metal surface in preparation for the painting process. Cover all the areas that you will not be painting with masking or painting tape. For example, doorknobs, door hinges, or any other fixtures that should be paint-free during the process. Make sure that you tape every place well so that they will remain paint-free.
- Wear protective clothing while removing rust or any old paint. Make sure that you put on a protective mask, especially if you are dealing with dust. You can opt for a wire brush to use in stripping down layers of old paint from the metal. Keep a damp cloth nearby so that you can use it in wiping off dust and dirt particles as you do your project.
- Use fine-grit sandpaper to clear any old paint and residue from the surface. Use an old rag to wipe the surface clean. You can dispose of the rag after use. You can use soapy water to wash the surface clean and leave it to dry. Sandpaper is the best choice to get rid of any uneven surface portions, thus making it smooth.
- Wipe it again with a damp rag that is clean. Always ensure that you thoroughly clean the surface so that your project will not be compromised in any way. Proper cleaning will also enable your paint to stick to the metal. You can also use a detergent mix to ensure that all oils have been properly wiped off the surface. Alcohol wipes also work very well when cleaning the surface and they make the process a bit faster. Then, leave it to dry again.
How to Prime the Metal
For this process to work effectively, you have to apply a primer. Opt for a primer that is highly compatible with acrylic paint. Make sure the primer has been specified for metals. Using the wrong primer will not produce your desired and expected results.
- Choose a primer that is suitable for the paint you will be using. It is best to buy a universal bottle that contains the paint and primer in one bottle. When buying a primer, choose a product that you can apply with ease. Primers come in a variety of containers that include spray cans, buckets, or cans. Your choice of container will also determine the type of tool you have to use during the application. You can use a brush to apply primers that come in buckets and cans.
- Begin the process by applying two coats, being sure to wait until the first coat is dry before applying the second one. It is very important to stick to the manufacturer’s recommended drying time. Once your surface has dried completely, you can begin the process of applying your paint.
- It is advisable to put a double coat of primer when dealing with a metal surface. This is because the metal surface is mostly prone to oxidization. Two coats of primer will ensure that your surface is protected from wear and tear and from being exposed to chemicals. A double-coat primer also enables your paint to stick well to the surface. You can opt for the primer below for better results.
RUST-OLEUM Flat White Clean Metal Primer Spray Paint
This bottle of metal primer can protect both your indoor and outdoor metallic surfaces from rust. You can apply it directly over rusted metal or you can use it on any painted metals to enhance durability and protect the surface from corrosion.
- Weather- and corrosion-resistant primer
- Oil-based formula provides a durable protective coating
- Creates a flat, white finish that can be covered with any topcoat
How to Paint and Seal Acrylics
For the painting process, you can use interior or outdoor acrylic paint. Begin the process by applying two coats of paint. Wait until the first coat has dried properly before painting the second coat. If you are using colors, then paint on top of the first coat of acrylic paint when it has dried properly. The following are important points to note when painting:
- Make sure that you shake the can very well to thoroughly mix the paint inside before you begin painting.
- To avoid drips, spray the paint from a distance of 8 to 10 inches from the surface. Make vertical and horizontal sweeps while spraying the paint.
- Multiple light coats with the proper drying time in-between are better than one single thick coat. This is because a single thick coat can run easily.
You should allow a drying time of at least 48 hours for the project to completely dry before using it. If you opt for exterior acrylic paint, then there will be no need to seal it after painting. Regular acrylic paint on an indoor project, however, will require an arylic spray sealant to protect your project. If you do not want to use a spray paint, you can also opt for using acrylic paints in an airbrush.

Tips and Tricks When Using Acrylic Paint on Metal
- Always wash your brushes whilst they are still wet with paint, because acrylic paint is water-soluble.
- If you want different colors on your project, make sure you paint the first coat of acrylic with another color and leave it to dry before applying the next coat.
- Always wear protective clothing or old clothes when working with acrylic paint so that you do not mess up your clothes.
- Acrylic paints have strong smells and a lot of people react to them. Ensure that you wear a face mask when working on your project. You should also work in a well-ventilated area, because rust and paint particles are harmful to health.
- Conduct thorough research before purchasing an acrylic paint so that you choose a product that is most suitable for your project. You can also opt for a primer from the same brand to save yourself from the stress of checking the compatibility of the paint to the primer.
- The proper use of a primer can help you in protecting your surfaces from rust.
- Make sure the final coat of paint takes at least 36 to 48 hours to dry completely. If you are likely to come into contact with the painted surface, then do your project in an isolated area where you will not damage the painted surface.
