As an artist, there’s nothing quite like the feeling of completing a beautiful acrylic painting. You’ve poured your heart and soul into the piece, and it’s finally ready to be displayed for the world to see. But before you can show it off, you need to make sure it’s properly protected. That’s where varnishing comes in – a crucial step in preserving the integrity and longevity of your artwork. In this article, we’ll explore the different types of sprays you can use to protect your acrylic paintings, as well as some important tips and considerations to keep in mind.
Why Varnish Your Acrylic Paintings?
Before we dive into the different types of sprays you can use, let’s talk about why varnishing is so important in the first place. Here are just a few reasons why you should consider varnishing your acrylic paintings:
- Protection from UV light: UV light can cause colors to fade and become brittle over time. Varnishing your painting with a UV-resistant spray can help protect it from these damaging effects.
- Dust and dirt protection: Varnish creates a barrier between your painting and the environment, protecting it from dust, dirt, and other contaminants that can damage the surface.
- Moisture protection: Varnish can help protect your painting from moisture, which can cause the acrylic paint to become brittle or even crack.
- Easy cleaning: A varnished painting is much easier to clean than an unvarnished one. Simply use a soft cloth and mild soap to wipe away any dirt or debris.
Types of Sprays for Acrylic Paintings
Now that we’ve covered the importance of varnishing, let’s talk about the different types of sprays you can use to protect your acrylic paintings. Here are a few options:
Acrylic Polymer Varnish
Acrylic polymer varnish is a popular choice among artists because it’s easy to use and provides excellent protection for acrylic paintings. This type of varnish is water-clear and non-yellowing, making it ideal for use on a variety of surfaces. It’s also UV-resistant and can be used on both flexible and rigid surfaces.
Matte Varnish
If you’re looking for a varnish that won’t add a glossy finish to your painting, consider using a matte varnish. This type of varnish is perfect for artists who want to maintain the original texture and appearance of their work. Matte varnish is also a good choice for paintings that will be displayed in a high-traffic area, as it can help reduce glare.
Satin Varnish
Satin varnish is a versatile option that offers a soft, subtle sheen. This type of varnish is perfect for artists who want to add a bit of depth and dimension to their work without creating a glossy finish. Satin varnish is also UV-resistant and can be used on a variety of surfaces.
Gloss Varnish
If you want to add a high-gloss finish to your painting, consider using a gloss varnish. This type of varnish is perfect for artists who want to create a bold, eye-catching effect. Gloss varnish is also UV-resistant and can be used on a variety of surfaces.
Things to Consider When Choosing a Varnish
When choosing a varnish for your acrylic painting, there are a few things to consider. Here are some key factors to keep in mind:

Application Method
There are a few different ways to apply varnish to your painting, including spraying, brushing, and pouring. Spraying is a popular option because it’s easy to use and provides a smooth, even finish. However, it can be messy, so make sure you’re working in a well-ventilated area and wearing protective gear.
Drying Time
Different varnishes have different drying times, so make sure you read the instructions carefully before applying. Some varnishes can take several hours or even days to dry completely, so plan accordingly.
Removability
Some varnishes are easier to remove than others, so make sure you choose a varnish that can be easily removed if needed. This is especially important if you’re working on a valuable or sensitive piece.

What is the purpose of spraying a sealant on acrylic paintings?
Spraying a sealant on acrylic paintings serves as a protective barrier against environmental factors that can damage the artwork. It helps to shield the painting from dust, UV light, and moisture, which can cause the colors to fade or the paint to crack over time. By applying a sealant, artists can ensure that their masterpiece remains vibrant and intact for years to come.
The sealant also provides a layer of protection against physical damage, such as scratches or spills. This is especially important for artworks that will be handled or displayed in public spaces. By sealing the painting, artists can have peace of mind knowing that their work is safeguarded against accidental damage.
What types of sealants can be used on acrylic paintings?
There are several types of sealants that can be used on acrylic paintings, including varnishes, acrylic polymers, and resin-based sealants. Varnishes are a popular choice among artists, as they are easy to apply and come in a range of sheens, from matte to glossy. Acrylic polymers are another option, offering a flexible and breathable barrier that won’t yellow over time.
Resin-based sealants are also available, providing a strong and durable protective layer. These sealants are often used on artworks that will be exposed to high levels of wear and tear. Regardless of the type of sealant chosen, it’s essential to read the instructions carefully and follow the manufacturer’s recommendations for application and drying times.
How do I choose the right sealant for my acrylic painting?
Choosing the right sealant for your acrylic painting depends on several factors, including the type of paint used, the surface texture, and the desired level of protection. If you’re looking for a high-gloss finish, a varnish may be the best option. For a more subtle sheen, an acrylic polymer or resin-based sealant may be a better choice.
It’s also important to consider the brand and quality of the sealant. Look for products that are specifically designed for use on acrylic paintings and follow the manufacturer’s instructions carefully. Reading reviews and doing research can also help you make an informed decision and ensure that you choose a sealant that meets your needs.
Can I use a sealant on a painting that has not fully dried?
It’s generally recommended to wait until the painting is fully dry before applying a sealant. Acrylic paint typically takes anywhere from a few days to a few weeks to fully dry, depending on the thickness of the application and the environmental conditions. Applying a sealant too soon can trap moisture in the paint, leading to a range of problems, including mold, mildew, and cracking.
If you’re eager to get your painting sealed, it’s best to wait at least 24 hours after the paint has dried to the touch. However, it’s always better to err on the side of caution and wait a few days or even a week before applying a sealant. This will ensure that the paint is fully dry and ready for sealing.
How do I apply a sealant to my acrylic painting?
Applying a sealant to your acrylic painting is a relatively straightforward process. Start by reading the instructions on the product label and making sure you have all the necessary materials, including a clean workspace, a spray bottle or brush, and a well-ventilated area. If using a spray sealant, shake the can well and hold it 8-10 inches away from the painting.
Spray the sealant in a steady, back-and-forth motion, making sure to cover the entire surface evenly. If using a brush-on sealant, apply a thin layer to the painting, working in small sections to avoid drips and runs. Regardless of the application method, make sure to follow the manufacturer’s instructions for drying times and recommended coats.
Can I use a sealant on a mixed-media artwork that includes acrylic paint?
Yes, you can use a sealant on a mixed-media artwork that includes acrylic paint. However, it’s essential to choose a sealant that is compatible with all the materials used in the artwork. Some sealants may not be suitable for use on certain materials, such as paper, fabric, or found objects.
Before applying a sealant, make sure to read the product label and look for any warnings or cautions about use on mixed-media artworks. It’s also a good idea to test the sealant on a small, inconspicuous area of the artwork to ensure that it won’t damage any of the materials.
How often should I reapply a sealant to my acrylic painting?
The frequency of reapplying a sealant to your acrylic painting depends on several factors, including the type of sealant used, the environmental conditions, and the level of wear and tear. As a general rule, it’s recommended to reapply a sealant every 5-10 years, or as needed.
If the painting is exposed to high levels of UV light, moisture, or physical handling, it may need to be resealed more frequently. Conversely, if the painting is stored in a cool, dry place and handled carefully, it may only need to be resealed every 10-20 years. Regular inspections of the painting can help determine when a reapplication of sealant is necessary.
