To make acrylic paint waterproof, you need to use a sealer like varnish or wax. Acrylic paints are used in a variety of diy projects like painting on canvases, wooden frames, and even on metal or plastic surfaces.
But not all acrylic paints are waterproof, and they can easily get tarnished if exposed to water or moisture for a prolonged period. Therefore, it is essential to make them water-resistant to increase their longevity and durability. The good news is that waterproofing your acrylic paint is quite an easy task; all you need to do is use the right sealer.
In this article, we will explore how you can make your acrylic paint waterproof by using different types of sealers like varnish, wax, and other waterproofing agents.
Understanding Acrylic Paints
The Composition Of Acrylic Paints And How They Differ From Other Types Of Paint
Acrylic paints are made up of pigment suspended in an acrylic polymer emulsion, making them water-soluble and easy to clean with soap and water. One of the main differences between acrylic paints and other types of paint is that they dry quickly, even when layered thickly, allowing artists to build up layers of paint and textures more efficiently.
Unlike oil-based paints, which require solvents for cleaning, acrylic paints are non-toxic, making them the perfect choice for artists who are sensitive to chemicals.
The Properties Of Acrylic Paints That Make Them A Suitable Medium For Artworks
Acrylic paints have unique properties that make them an excellent choice for artists. Here are some of the most important ones:
- Acrylic paints are versatile and can be used on a variety of surfaces, including canvas, paper, wood, and fabric.
- They can be thinned with water to create a watercolor-like effect or used straight out of the tube for thick, impasto work.
- They have excellent adhesive qualities, allowing artists to mix them with a wide range of mediums, including gels and pastes, to create varying textures and finishes.
- Acrylic paints are resistant to fading, flaking, and aging, making them a great choice for artworks that will stand the test of time.
Common Challenges With Acrylic Paints
While acrylic paints have many excellent qualities, they can also present some challenges for artists. Some of the most common issues to watch out for include:
- Cracking and peeling when exposed to moisture or extreme temperatures. To prevent this, artists should ensure that their painting surface is clean and free from dust, oil, or other contaminants.
- Difficulty blending or softening the edges of a painted area once the paint has started to dry. To overcome this issue, artists can employ a range of techniques, including blending mediums, glazing, or wet-on-wet painting techniques.
- Drying too quickly on the palette, making it challenging to mix colors or work on a painting for an extended period. To prevent this, artists can use a palette paper that keeps the paint moist for several hours or use a stay-wet palette.
Choosing The Right Waterproofing Technique
Factors To Consider When Choosing A Waterproofing Technique
When trying to make acrylic paint waterproof, it is essential to consider various factors to ensure that you choose the best technique for your needs. Here are some crucial factors to bear in mind:
- Purpose: Why do you need to waterproof your acrylic paint? Is it for outdoor or indoor use? Will the painting be exposed to water or moisture?
- Surface: What surface will you be painting on? Some surfaces might require a specific waterproofing technique.
- Drying time: How long can you wait for the paint to dry before waterproofing?
- Budget: How much are you willing to spend on the waterproofing technique?
Overview Of Different Waterproofing Techniques
When it comes to making acrylic paint waterproof, several techniques can help protect your artwork from water damage. Here are some of the most popular options:
- Clear sealants: Apply a clear sealant over your acrylic paint to protect it from water damage. This technique is suitable for both indoor and outdoor use and is relatively affordable.
- Acrylic varnish: This technique involves using a varnish that is specially designed for acrylic paint. It creates a protective layer that can withstand exposure to water and moisture.
- Epoxy resin: This technique is suitable for paintings that need robust protection from water damage. A thick layer of resin is applied to the painting, giving it a glossy finish and making it waterproof.
- Silicone spray: Applying silicone spray over your acrylic paint can make it waterproof. However, this technique is not suitable for all surfaces and needs to be reapplied regularly.
- Polymer medium: This technique mixes the paint with a polymer medium, creating a waterproof layer. However, it can alter the paint’s appearance, and the application process can be time-consuming.
When choosing a waterproofing technique for your acrylic paint, be sure to consider the factors mentioned above and weigh the pros and cons of each option. With the right technique, you can protect your artwork from water damage and ensure that it lasts for years to come.
How To Varnish Your Acrylic Painting
Acrylic paintings are a beautiful and vibrant addition to any art collection. However, it’s important to protect your acrylic paintings from moisture, dust and other harmful elements that can damage them over time. Applying varnish on your acrylic painting is essential to protect its surface, enhance its colors, and make it waterproof.
We’ll show you how to varnish your acrylic painting step-by-step.
Understanding Different Types Of Varnish
Before you start varnishing your acrylic painting, it’s important to understand the different types of varnish available in the market. Here are the three most common types of varnish you can use on your acrylic painting:
- Polymer varnish: This type of varnish is water-based, dries clear, and doesn’t contain any solvents. It’s ideal for indoor acrylic paintings as it provides a clear, glossy finish.
- Solvent-based varnish: As the name implies, solvent-based varnish contains solvents such as mineral spirits or turpentine. It’s ideal for outdoor acrylic paintings as it provides uv protection and is more durable than polymer varnish.
- Acrylic varnish: This type of varnish is designed specifically for acrylic paintings, and it comes in both water-based and solvent-based options. It’s versatile, easy to apply, and provides a clear, glossy finish.
Tools And Materials Needed For Applying Varnish
Before you start applying varnish to your acrylic painting, make sure you have the following tools and materials:
- A clean and dry work surface
- A clean and dry paintbrush or foam brush
- Varnish (polymer, solvent-based, or acrylic)
- Flexible sanding pad or fine-grit sandpaper (optional)
- A stirring stick (if using a solvent-based varnish)
- Mineral spirits or turpentine (if using a solvent-based varnish)
Step-By-Step Guide To Varnishing Your Acrylic Painting
Follow these easy steps to varnish your acrylic painting, protect it, and make it waterproof:
- Wait until your acrylic painting is completely dry. Ideally, wait for at least 48 hours or more if the painting is thick or has impasto textures.
- Decide which varnish you want to use depending on your painting’s needs – polymer, solvent-based or acrylic.
- Work in a well-ventilated room and on a clean and dry work surface.
- Grab your paintbrush or foam brush and dip it into the varnish. Be sure to load it with enough varnish, but not too much that it drips.
- Apply the varnish evenly on the painting surface, starting from the top to bottom or from one side to the other, in long, even strokes. Avoid going over the same area twice as it can create uneven textures.
- If you see some bubbles or bumps, gently blow on them or remove them with your brush. Be careful not to overdo it as it can create streaks or smudges.
- Wait for the first coat of varnish to dry completely. Depending on the type of varnish you use and the humidity, it can take anywhere from a few minutes to a few hours.
- Apply the second coat of varnish in the same manner as the first coat. Allow it to dry.
- Check the painting after the second coat of varnish is completely dry. If your painting has impasto textures, or you notice some spots or uneven areas, you can use a flexible sanding pad or fine-grit sandpaper to smooth it out. Use gentle, even strokes and wipe off any dust or grit with a clean cloth.
- You’re done! Your acrylic painting is now waterproof and protected.
