Can Acrylic Paint Be Used Outdoors?
For artists and DIY enthusiasts, using acrylic paint for outdoor projects can seem appealing. Acrylics dry quickly, have vivid colors, and are easy to clean up. But how well does acrylic paint hold up when exposed to the elements outside? Let’s take a closer look at using acrylics outdoors.
If you’re short on time, here’s the quick answer: Acrylic paint can be used successfully outdoors if properly sealed and prepared to withstand exposure to sunlight, water, and temperature changes. Priming surfaces, using weatherproof varnishes, maintaining coats over time, and selecting paints formulated for outdoors will help acrylics endure outside.
Acrylic Paint Basics
Chemistry of acrylics
Acrylic paint is a popular choice among artists due to its versatility and durability. It is made from a combination of pigments and a synthetic polymer emulsion. The polymer emulsion, which is made up of tiny particles of acrylic resin, acts as a binder that holds the pigments together.
This binder gives acrylic paint its unique properties, such as quick drying time and water resistance.
When acrylic paint dries, the water in the emulsion evaporates, leaving behind a solid layer of pigment. This layer is flexible and can adhere to a wide range of surfaces, including canvas, wood, metal, and even plastics.
The ability of acrylic paint to adhere well to different surfaces makes it a suitable option for outdoor projects.
Advantages of acrylics
Using acrylic paint outdoors has several advantages. Firstly, it is highly resistant to fading and yellowing caused by exposure to sunlight. This makes it ideal for outdoor artwork or murals that will be exposed to the elements.
Acrylic paint also has excellent color retention, so your artwork will maintain its vibrancy for a long time.
Another advantage of acrylic paint is its fast drying time. Unlike oil paint, which can take days or even weeks to dry, acrylic paint dries within minutes or hours, depending on the thickness of the paint layer.
This allows artists to work quickly and make adjustments to their artwork without waiting for long drying periods.
Additionally, acrylic paint is known for its versatility. It can be used in thin washes or built up in thick layers, allowing artists to create a variety of textures and effects. It can also be mixed with other mediums, such as gels or modeling paste, to achieve different finishes and add depth to the artwork.
Limitations of acrylics
While acrylic paint has many advantages, it also has some limitations when used outdoors. One limitation is that acrylic paint can become brittle in extreme cold temperatures. If you live in a region with harsh winters, it is important to protect your outdoor acrylic artwork by applying a varnish or sealant to prevent cracking.
Another limitation is that acrylic paint is not as durable as oil paint. It can be more prone to chipping or peeling, especially if the surface it is applied to is not properly prepared. To ensure the longevity of your outdoor acrylic artwork, it is recommended to prime the surface with a suitable primer and apply multiple layers of varnish for added protection.
Preparing Surfaces for Outdoor Acrylic Paint
Choosing the right surface materials
When it comes to using acrylic paint outdoors, selecting the appropriate surface materials is crucial for achieving long-lasting and successful results. Some common surface options for outdoor projects include:
- Wood: Opt for weather-resistant woods like cedar or redwood, as they are less prone to rotting or warping when exposed to the elements.
- Metal: Look for metals that are resistant to rust and corrosion, such as aluminum or stainless steel.
- Concrete: Ensure that the concrete surface is clean, smooth, and free of any cracks or imperfections.
- Plastic: Choose plastics that are specifically designed for outdoor use, as they are more durable and UV-resistant.
By selecting the right surface materials, you can ensure that your outdoor acrylic paint adheres well and withstands the test of time.
Cleaning and priming surfaces
Before applying outdoor acrylic paint, it is important to thoroughly clean and prime the surfaces. This helps to create a smooth and even base for the paint to adhere to, ensuring better adhesion and longevity.
To clean the surfaces, use a mild detergent mixed with water and a scrub brush or sponge. This will remove any dirt, grease, or grime that may interfere with the paint’s adhesion. Rinse the surfaces thoroughly and allow them to dry completely before proceeding.
Once the surfaces are clean, it is time to prime them. Using a high-quality primer specifically formulated for outdoor use will provide additional protection and promote better paint adhesion. Apply the primer evenly with a brush or roller, following the manufacturer’s instructions for drying time.
By properly cleaning and priming the surfaces, you can enhance the durability and longevity of your outdoor acrylic paint project, ensuring that it stays vibrant and beautiful for years to come.

Sealing and Protecting Outdoor Acrylic Paint
When it comes to using acrylic paint outdoors, one important consideration is how to seal and protect the paint from the elements. Without proper sealing, outdoor acrylic paint can be susceptible to fading, cracking, or peeling over time.
Luckily, there are several methods and products available to help ensure your outdoor acrylic paint withstands the test of time.
Picking durable, UV-resistant varnishes
One effective way to seal outdoor acrylic paint is by applying a durable varnish that is specifically designed for outdoor use. These varnishes provide an extra layer of protection against UV rays, moisture, and other environmental factors.
Look for varnishes that are labeled as UV-resistant or have a high level of UV protection to ensure your paint stays vibrant and durable.
Popular brands such as Liquitex, Golden, and Winsor & Newton offer a range of varnishes that are suitable for outdoor acrylic paint. Make sure to read the product labels and instructions to determine if the varnish is compatible with your specific type of paint and surface.
Applying waterproofing topcoats
In addition to varnishes, applying a waterproof topcoat can provide an extra layer of protection for your outdoor acrylic paint. Waterproof topcoats create a barrier that helps prevent water damage, fading, and discoloration.
They are especially useful for outdoor acrylic art installations, murals, or any other projects exposed to rain, snow, or high humidity.
One popular waterproof topcoat option is a clear acrylic spray. This type of spray forms a protective layer that is resistant to water and other environmental elements. It is important to apply the spray in thin, even coats, allowing sufficient drying time between each layer.
This will ensure proper coverage and a long-lasting seal.
Maintaining sealants over time
While using varnishes and waterproof topcoats can significantly extend the lifespan of outdoor acrylic paint, it is important to maintain these sealants over time. Regularly inspect the painted surface for any signs of wear or damage, and reapply varnishes or topcoats as needed.
This will help protect the paint from fading or deteriorating due to exposure to the elements.
It’s worth noting that even with proper sealing and maintenance, outdoor acrylic paint may still experience some degree of fading or weathering over time. However, by following these sealing and protecting techniques, you can greatly increase the longevity and durability of your outdoor acrylic paint projects.
