So read on and see how you can simply make your acrylic paints waterproof.

Understanding Acrylic Paint & The Importance of Waterproofing:

Acrylic paint is a popular medium for painting because of its fast-drying, versatile, and durable qualities. While acrylic paint dries quickly, it is still vulnerable to water damage and must be treated to make it waterproof.

As any artist knows, water can easily ruin a wet or dry painting. Paint made with water, like acrylic paint, can be hurt by too much water. The paint can change color or even disappear if it is not sealed correctly. This happens when the paint is exposed to moisture.

Using waterproof paint can help a painting or art project stay in good condition. It will stop the colors from running, smearing, or becoming lighter when it gets wet.To effectively waterproof acrylic paint, you will need the right supplies and a bit of patience.

There are several methods available for waterproofing acrylic paint. The most common is by using sealers, varnishes, and other finishes. You need to experiment with different waterproofing products until you find one that best suits your needs.

13 Best Ways on How to Make Acrylic Paint Waterproof:

#1. Using Varnish: 

Applying a thin layer of spray or brush-on varnish to your painting can create a waterproof seal, protecting it from humidity and moisture.

Using Varnish

Most varnishes are made of acrylic polymers or resins and come in gloss, matte, and satin finishes. If you want to fix mistakes or add texture, you can use a special matte varnish that won’t alter the color of your paint.

#2. Using Epoxy: 

Epoxy resin is a strong adhesive and sealant that can be used to waterproof acrylic paints. This two-part mixture creates an impenetrable protective layer over the surface of your painting, preventing any moisture or air from getting in. 

Epoxy is the most durable option for waterproofing and will last longer than other methods.

But it can also be tricky to apply and is best left to professional conservators. If you plan on using epoxy resin, read the instructions carefully and use a respirator for safety. 

#3. Applying Wax:

Using wax is another way to waterproof acrylic paints. Wax is used to protect paintings. It creates a layer that does not let moisture in.

Wax comes in different forms like liquid, paste, and beeswax. When you apply it, use a cloth without lint. You may need to do it several times.

Make sure you read the instructions and test it on a small part before putting wax on the whole painting. 

#4. Apply Mod Podge:

Mod Podge is a popular sealant for craft projects, and it can also be used to waterproof acrylic paintings. This method works by creating a glossy, protective layer on the surface that will seal the painting and make it look attractive. 

Apply Mod Podge

For best results, avoid applying Mod Podge in one thick coat and instead opt for multiple light coats to prevent air bubbles. Use a foam brush to apply each coat evenly and avoid leaving streaks or clumps. 

Wait until one coat of paint is dry before putting on the next coat. Ensure all the coats are completely dry, which can take 24 hours or more. This way will make your artwork safe from weather and other things that might damage it. It works with both oil and acrylic paints. 

#5. Using Polyurethane:

Polyurethane is another great option for protecting your artwork from damage. It creates a glossy, protective finish that can seal in the colors and prevent the painting from fading over time. 

Polyurethane is also water-resistant, so it can help keep your artwork safe from moisture damage. If you want a glossy finish, you can apply multiple coats of polyurethane. 

Use a brush with soft bristles and spread the product evenly across the entire painting. You should also let each coat dry completely before applying the next one. 

#6. Using Acrylic Sealer:

For a more matte, less glossy finish, you can use an acrylic sealer. This is a great option for protecting artwork from dirt and dust without changing the texture. 

It’s also easy to apply and requires no additional tools or materials. Simply spray the sealer onto the painting in a light and even coat. 

Let it sit for about an hour, and then wipe off any excess with a lint-free cloth. This will help the sealer last longer and protect your artwork from potential damage. 

#7. Using Nail Polish:

Although it isn’t the ideal way to seal a painting, nail polish can be an effective way of doing so. This method works best with artwork on paper or board, as the nail polish can damage the canvas. 

Using Nail Polish

To apply this method, start with a thin layer of clear nail polish over the entire painting. Allow it to dry for at least 24 hours, and then apply a second coat if desired. 

Make sure to keep the nail polish away from any areas that could be damaged by it, such as around the edges or near any textured surfaces. Once dry, you can protect your painting from any humidity or moisture.

#8. Apply Glazing Medium:

Glazing medium is an ideal sealant for painting surfaces, such as canvas or wood. This technique works best when used on paintings with dull colors or needing additional protection. 

Using a glazing medium will help lock in the vibrancy of your artwork and protect it from fading over time. 

To apply the glazing medium, mix it with a small amount of water until it forms a thin paste. 

Then use a paint brush to brush the mixture over your entire painting lightly. 

Be sure to avoid any areas that could be damaged by it, such as around the edges or near any textured elements. Wait until the sealant dries. This will help protect your artwork from dust, sunlight, and moisture. 

#9. Baking the Acrylic Paint:

Baking your acrylic paints can add a beautiful finish to your artwork and protect it for years to come.

To bake the paint, you’ll need to preheat your oven to about 350 degrees Fahrenheit and place the painting on a flat baking sheet. Bake it for around 30 minutes, keeping a close watch on the paint to ensure it doesn’t burn.

Once the paint is hardened and cool, you can take your artwork off the baking sheet and enjoy your creation! Remember never to leave the painting unattended while it is in the oven. 

#10. Acrylic Polymer Medium:

You can use acrylic polymer medium for a professional finish on top of your painting. This will further protect it and make the colors more vibrant. Mix the polymer medium with your acrylic paint to create a paste. 

Use Acrylic Polymer Medium

Brush this mixture onto the painting and allow it to dry overnight. Once it completely dries, the painting should be protected from scratches and fading.

You can also opt for a glossy finish by applying two layers of this mixture. This will give your painting a beautiful sheen and make it stand out! 

#11. Use Uv Protected Laminating Sheets:

A great way to protect your painting is by laminating it. This will protect your artwork from dust, dirt, scratches, and fading. It will also make the colors look brighter and more vibrant. 

You only need to pick up a roll of UV-protected laminating sheets from your local craft store and use a laminator to seal the edges. This will give you a professional finish that is sure to last for years. But make sure you use cold laminating techniques to avoid any heat damage. 

#12. Sealing With Waterproof Glue:

If you want a more permanent way to protect your painting, try sealing it with waterproof glue. This method is simple and effective. Just apply a thin layer of waterproof glue all over the painting and let it dry. 

This will ensure that your artwork is resistant to spills and moisture and will keep it looking great for years to come. Plus, it won’t damage the painting in any way. 

#13. Applying PVA Glue:

If you want to make sure your painting is extra secure, applying PVA glue can help. This type of glue is a clear, water-soluble adhesive that won’t damage the artwork and provides a strong bond. 

Applying PVA Glue

Just apply a thin layer of PVA glue all over the painting and let it dry. Your artwork should now be protected from any kind of water or moisture damage, and it will remain looking great for years to come. 

These are just a few tips for preserving your artwork and ensuring it lasts a lifetime. With these ideas on how to make acrylic paint waterproof, you can ensure that your painting will stay in great condition for many years to come.

How to Seal Acrylic Paint for Outdoor Use?

When you are looking for a way to seal acrylic paint for outdoor use, a few options are available. The most important factor when sealing acrylic paint is to ensure it is completely dry before applying any sealant.

How to Seal Acrylic Paint for Outdoor Use

One option for sealing acrylic paint outdoors is using a clear sealer. This will provide a protective layer while still allowing the colors of the paint to show through. 

When painting outside, buying a sealer that says it is for the outdoors is important. The paint may fade in the sun if you don’t use an outdoor sealer. 

Another option is to use a specialized outdoor paint sealer. These are usually designed for specific paints and finishes, so selecting the right one for your project is essential. 

Outdoor paint sealers can provide a very durable protective layer and can help protect from fading, cracking, and other damage. 

Frequently Asked Questions:

Does acrylic paint come off in rain? 

No, acrylic paint is water-resistant when dry. This means that it will not easily come off in the rain. However, if the paint is not sealed, it can be vulnerable to wear and tear. 

Sealing it with a quality varnish or other protective coating is vital to ensure the paint remains protected for a long time. This will help the paint resist moisture and last longer.

Is acrylic waterproof on different surfaces?

Yes, acrylic paint is waterproof on various surfaces, including wood, metal, plastic, and fabric. Use an appropriate sealer for each surface to ensure the paint adheres properly. 

Additionally, you may need a primer before painting on some surfaces. This will help improve the paint’s adherence and longevity. 

As with any other paint, regular maintenance is important to ensure that acrylic paint continues to look its best. Regularly cleaning and re-applying a sealer will keep the paint from fading or wearing off over time. 

Can you varnish over acrylic paint? 

Yes, you can varnish over acrylic paint. Varnishing is an optional step that can be used to add a glossy or matte finish to your acrylic painting. Varnish also helps protect the paint from dust, dirt, and other environmental damage. 

However, ensuring the acrylic paint is completely dry before applying the varnish is really important. Applying varnish over wet paint can cause the paint to discolor or streak, ruining your work of art. 

Make sure you read the label before you buy varnish. You need to buy a varnish made for acrylic paint. Put on thin layers of the varnish and let each layer dry before adding another one. This will ensure your painting is protected without cloudiness or color changes.
