How to Make Acrylic Paint Waterproof: Exploring the Art of Preservation and Beyond

Acrylic paint is a versatile medium beloved by artists for its vibrant colors, quick drying time, and ease of use. However, one common challenge artists face is making acrylic paint waterproof. Whether you’re creating outdoor murals, painting on surfaces exposed to moisture, or simply want to ensure the longevity of your artwork, waterproofing acrylic paint is a crucial step. In this article, we’ll explore various methods to achieve this, delve into the science behind acrylic paint, and discuss creative ways to enhance its durability. Along the way, we’ll also touch on how waterproofing connects to broader artistic practices and philosophies.


Understanding Acrylic Paint: The Basics

Before diving into waterproofing techniques, it’s essential to understand what acrylic paint is and how it behaves. Acrylic paint consists of pigment suspended in an acrylic polymer emulsion. When the paint dries, the water evaporates, leaving behind a flexible, water-resistant film. However, this film is not entirely waterproof and can still be affected by prolonged exposure to moisture.

Why Waterproofing Matters

  • Outdoor Artwork: If your painting is exposed to rain or humidity, waterproofing ensures it remains intact.
  • Functional Items: Acrylic paint is often used on surfaces like ceramics, wood, or fabric, which may require washing or exposure to water.
  • Longevity: Waterproofing protects your artwork from damage over time, preserving its vibrancy and integrity.

Methods to Make Acrylic Paint Waterproof

1. Using a Varnish

Varnishing is one of the most common and effective ways to waterproof acrylic paint. Varnishes come in various finishes (matte, satin, gloss) and provide a protective layer over the paint.

  • Steps:

    1. Ensure your painting is completely dry.
    2. Apply a thin, even coat of acrylic varnish using a brush or spray.
    3. Allow it to dry according to the manufacturer’s instructions.
    4. Apply a second coat for added protection.
  • Types of Varnish:

    • Polyurethane Varnish: Highly durable and waterproof, ideal for outdoor use.
    • Acrylic Varnish: Less toxic and easier to clean up, but may require more frequent reapplication.

2. Mixing with a Medium

Acrylic mediums can be mixed directly into the paint to enhance its properties, including water resistance.

  • Popular Mediums:

    • Acrylic Gloss Medium: Adds a glossy finish and increases water resistance.
    • Acrylic Matte Medium: Provides a matte finish while improving durability.
    • Gel Medium: Thickens the paint and adds texture while enhancing waterproofing.
  • How to Use:

    1. Mix the medium with your paint in a 1:1 ratio or as recommended by the manufacturer.
    2. Apply the mixture as usual, ensuring even coverage.

3. Sealing with a Waterproof Sealant

For surfaces that will be frequently exposed to water, such as ceramics or outdoor furniture, a waterproof sealant is a reliable option.

  • Options:

    • Epoxy Resin: Creates a thick, glass-like coating that is fully waterproof.
    • Polycrylic Sealant: A water-based sealant that dries clear and provides excellent protection.
  • Application Tips:

    • Apply in a well-ventilated area.
    • Use a brush or sponge for even application.
    • Allow ample drying time between coats.

4. Heat Setting

Heat setting is particularly useful for acrylic paint on fabric. This method uses heat to bond the paint to the fabric, making it more resistant to washing.

  • Steps:
    1. Allow the painted fabric to dry completely.
    2. Place a piece of parchment paper over the design.
    3. Iron the area on a medium-high setting for 3-5 minutes.
    4. Let it cool before testing its water resistance.

5. Layering with Clear Gesso

Clear gesso can be used as a base coat or top coat to add texture and improve the paint’s adhesion and water resistance.

  • How to Apply:
    1. Apply a thin layer of clear gesso to your surface before painting.
    2. Alternatively, use it as a top coat after the paint has dried.

Creative Applications and Philosophical Musings

Waterproofing acrylic paint isn’t just a technical process; it’s also an opportunity to explore the intersection of art and science. By experimenting with different methods, artists can push the boundaries of their creativity while ensuring their work stands the test of time.

The Art of Preservation

Preserving artwork is akin to preserving memories. Just as we protect our creations from the elements, we also strive to safeguard the emotions and stories they convey. Waterproofing becomes a metaphor for resilience, reminding us that art, like life, requires care and attention to endure.

Beyond Waterproofing: Exploring Texture and Depth

While waterproofing is practical, it also opens doors to new artistic possibilities. For instance, using epoxy resin not only protects your painting but also adds a glossy, three-dimensional effect that enhances its visual appeal. Similarly, mixing mediums can alter the texture and finish of your work, allowing you to experiment with different styles.


Frequently Asked Questions

1. Can I use hairspray to waterproof acrylic paint?

While hairspray can provide a temporary protective layer, it is not a reliable long-term solution for waterproofing. Over time, hairspray may yellow or become sticky, compromising the integrity of your artwork.

2. How many coats of varnish should I apply?

Two to three coats of varnish are generally recommended for optimal protection. Ensure each coat is completely dry before applying the next.

3. Is waterproof acrylic paint safe for skin?

Even when waterproofed, acrylic paint is not intended for use on skin. For body art, always use products specifically designed for skin application.

4. Can I waterproof acrylic paint on canvas?

Yes, varnishing or using a sealant is an effective way to waterproof acrylic paint on canvas. Ensure the paint is fully dry before applying any protective layer.

5. How do I remove waterproofing from acrylic paint?

Removing waterproofing can be challenging. For varnishes, you may use a solvent like mineral spirits, but this can also affect the underlying paint. Always test on a small, inconspicuous area first.


By mastering the art of waterproofing acrylic paint, you not only protect your creations but also unlock new avenues for artistic expression. Whether you’re a seasoned artist or a beginner, these techniques will help you create durable, long-lasting works of art that can withstand the test of time—and the elements.
