How To Seal Acrylic Pour Paintings: An Easy Beginner’s Guide

Sealing acrylic pour paintings is essential for their protection and longevity. Two main methods are brush-on and spray varnish, each with its own pros and cons.

Preparing the painting surface is important, including applying an isolation coat. Some tips and tricks for sealing include using PVA glue, epoxy resin, or silicone oil.

Major supply stores like Michaels, Hobby Lobby, Amazon, Home Depot, Lowe’s, Blick Art Materials, Jerry’s Artarama, and Walmart offer sealants for purchase.

Different Ways to Seal Acrylic Pour Painting

When it comes to sealing your acrylic pour painting, there are two main ways to go about it: using a brush-on varnish or using a spray varnish. Each method has its pros and cons, so let’s explore them in more detail.

Using Brush-On Varnishes

If you prefer more control over the application process, using a brush-on varnish might be the best option for you.

This method allows you to apply the sealant in a more deliberate and precise manner, allowing you to create brush strokes and texture that can add to the overall aesthetic of your painting.

There are various types of sealants you can use for brush-on varnish, including acrylic sealers, acrylic polymer varnish, acrylic resin varnish, and polyurethane sealer.

Each type offers a different type of finish, from a matte varnish to a high-gloss finish. It’s important to choose the type of finish that best suits your painting.

When applying a brush-on varnish, it’s crucial to make sure your painting is completely dry before starting. Apply the first coat with a wide base coat brush, making sure to go in the same direction (horizontal or vertical) using the width of the brush.

Wait for the first coat to dry before applying a second coat going in the opposite direction of the first coat. Repeat this process until you achieve the desired level of protection and finish.

Using a Spray Varnish

If you’re looking for a quick and easy way to seal your acrylic pour painting, using a spray varnish might be the best option for you. Spray varnish allows you to apply the sealant evenly and quickly, without the need for a brush.

There are different types of spray varnishes available, including removable varnish and protective coat. Spray varnish comes in different finishes, including matte, satin, semi-gloss, and high-gloss finish. It’s important to choose the type of finish that best suits your painting.

When using a spray varnish, make sure to apply the sealant in a well-ventilated area, following the instructions on the can.

Hold the can about 8-10 inches away from the painting and spray in a sweeping motion, making sure to cover the entire surface. Allow the first coat to dry before applying a second coat if necessary.

In conclusion, whether you choose to use a brush-on varnish or a spray varnish to seal your acrylic pour painting, it’s important to choose the type of sealant that best suits your painting and to follow the instructions carefully.

With the right sealant and application method, you can achieve a smooth and protective finish that will enhance the beauty of your painting.

Preparing the Painting Surface

When it comes to sealing your acrylic pour painting, preparation is key. Preparing the painting surface involves selecting the right surface and applying an isolation coat.

Choosing the Right Surface

The type of surface you choose for your acrylic pour painting can greatly affect the outcome of your sealant. Here are some options to consider:

Smooth surfaces: Smooth surfaces, such as glass or metal, are ideal for acrylic pour paintings. They allow for a smooth and even application of sealant.

Wooden surfaces: Wooden surfaces such as wooden panels are also a popular choice for acrylic pour paintings. It is important to ensure that the surface is sanded and smooth before applying any sealant.

I actually did an acrylic pour on old wood furniture like a wooden chair and then coated it in an epoxy resin. I wish I had kept it now.

Uneven surfaces: If your acrylic pour painting has an uneven surface, it may be difficult to apply sealant evenly. In this case, it may be best to consider sanding the surface or using a spray-on sealant.

Applying an Isolation Coat

Before applying any sealant to your acrylic pour painting, it is important to apply an isolation coat. An isolation coat is a thin layer of clear acrylic medium that is applied to the surface of the painting.

This layer helps to protect the painting from any potential damage caused by the sealant.

To apply an isolation coat, follow these steps:

  1. Mix together equal parts of water and clear acrylic medium.
  2. Use a wide brush to apply the mixture to the surface of the painting.
  3. Allow the isolation coat to dry completely before applying any sealant.

By taking the time to properly prepare your painting surface, you can ensure that your acrylic pour painting is properly sealed and protected for years to come.

Sealing the Acrylic Pour Painting

When it comes to sealing your acrylic pour painting, it’s important to use a protective layer to ensure that your artwork lasts for a long time. Applying a sealer will protect the paint layer from dust, dirt, and other environmental factors. Here are some tips on how to seal your acrylic pour painting.

Applying the First Coat

Before you start sealing your painting, make sure that it is completely dry. Applying a sealer to a wet painting can cause the colors to blend together and ruin the artwork. Once your painting is dry, you can start applying the first coat of acrylic paint sealer.

It’s best to apply thin layers of sealer, rather than one thick coat. This will ensure that the sealer dries evenly and doesn’t take too much time to dry. If you apply too much sealer at once, it can take much time to dry and can ruin your painting.

When applying the sealer, use a wide brush to ensure that you cover the entire surface of the painting. Make sure that you apply the sealer in the same direction, either horizontal or vertical, to ensure that the coat is even.

Applying the Second Coat

Once the first coat is completely dry, you can start applying the second coat. This coat should be applied in the opposite direction of the first coat. For example, if you applied the first coat horizontally, apply the second coat vertically.

Make sure that you apply thin layers of acrylic paint sealer to ensure that it dries evenly. Applying too much sealer at once can cause excess water to build up on the surface of the painting, which can ruin your artwork.

Different types of paint may require different amounts of sealer. For example, darker colors may require more sealer than lighter colors.

Different paint brands may require different amounts of sealer. It’s always best to follow the manufacturer’s instructions when it comes to applying a sealer to your acrylic artwork.

Sealing your acrylic pour painting will ensure that it lasts a long time. By applying these thin layers of sealer in the same direction, you will get the best results.

Remember to let each coat dry completely before applying the next coat. With these tips, you can protect your artwork and enjoy it for years to come.

Tips and Tricks for Sealing Acrylic Pour Painting

When it comes to sealing your acrylic paint pour art, there are a few tips and tricks that can help you achieve the best results. Here are some methods or materials you can use when learning how to seal acrylic pour paintings:

Using PVA Glue

PVA glue is one of the most popular methods for sealing acrylic pour painting. It is a water-based sealant that becomes water-resistant once dry and can protect your painting from environmental damage. Here are the steps to using PVA glue:

  1. Mix equal parts of PVA glue and water in a container.
  2. Use a clean cloth or paper towel to apply the mixture to your painting in thin, even layers.
  3. Let each layer dry completely before applying the next one.
  4. Apply at least three layers of the PVA glue mixture to ensure maximum protection.

Using Epoxy Resin

Epoxy resin is another popular method for sealing acrylic pour painting. It provides a glossy finish and is perfect for outdoor use. Here are the steps to using epoxy resin:

  1. Mix the epoxy resin according to the manufacturer’s instructions.
  2. Pour the mixture onto your painting, spreading it evenly with a clean cloth or paper towel.
  3. Let the resin cure for at least 24 hours before handling the painting.
  4. Apply a second coat of epoxy resin if needed.

Using Silicone Oil

The use of Silicone oil is a great way to create cells in your acrylic pour painting, but it can also be used as a sealant. Here are the steps to using silicone oil:

  1. Mix equal parts of silicone oil and water in a container.
  2. Use a clean cloth or paper towel to apply the mixture to your painting in thin, even layers.
  3. Let each layer dry completely before applying the next one.
  4. Apply at least three layers of the silicone oil mixture to ensure maximum protection.

Remember, the key part of learning how to seal acrylic pour paintings is choosing the best sealant for your acrylic pour painting depends on your personal preference and the type of surface you’re working on.

Always use a clean cloth or paper towel to apply the sealant, and avoid exposing your painting to direct sunlight or UV rays. With these tips and tricks, you’ll be able to seal your acrylic pour painting with ease and confidence.
