Spray paint is a versatile and convenient solution for a wide range of projects, from DIY crafts to outdoor furniture restoration. However, one of the most common questions is, “Is spray paint waterproof?” The answer depends on the type of spray paint, its formulation, and the surface it’s applied to. In this article, we’ll explore everything you need to know about waterproof spray paint, including is Rustoleum spray paint waterproof, is Krylon spray paint waterproof, and the best waterproof spray paint for wood and plastic.

Is Spray Paint Waterproof?
The short answer is: It depends. Not all spray paints are created equal. Some are designed to be waterproof, while others are merely water-resistant. Here’s a breakdown:
- Waterproof spray paint: Forms a durable, impermeable layer that prevents water from penetrating the surface. Ideal for outdoor use or items exposed to moisture.
- Water-resistant spray paint: Can withstand light exposure to water but may degrade over time with prolonged contact.
If you’re working on a project that will be exposed to the elements, such as outdoor furniture or garden decor, it’s essential to choose a weatherproof spray paint or waterproof outdoor spray paint.
Is Rustoleum Spray Paint Waterproof?
Rustoleum is one of the most popular brands for durable, high-quality spray paints. Many of their products are specifically designed to be waterproof and weather-resistant. For example:
- Rustoleum Painters Touch Ultra Cover: Offers excellent water resistance and durability.
- Rustoleum Protective Enamel: Provides a waterproof, rust-resistant finish ideal for metal surfaces.
- Rustoleum Clear Coat: Adds a waterproof, protective layer over painted surfaces.
If you’re wondering, “Is Rustoleum waterproof?”, the answer is yes—many of their products are formulated to withstand moisture and harsh weather conditions.
Is Krylon Spray Paint Waterproof?
Krylon is another trusted brand known for its high-performance spray paints. Many Krylon products are water-resistant, but not all are fully waterproof. For example:
- Krylon COLORmaxx: Offers excellent adhesion and water resistance.
- Krylon Fusion All-In-One: Specifically designed for plastic, it provides a durable, water-resistant finish.
- Krylon Clear Coat: Adds a waterproof layer to protect painted surfaces.
If you’re looking forwaterproof spray paint for plastic, Krylon Fusion All-In-One is an excellent choice.
Waterproof vs. Water-Resistant Spray Paint
Understanding the difference between waterproof and water-resistant spray paint is crucial for choosing the right product for your project:
- Waterproof spray paint: Completely blocks water penetration, making it ideal for surfaces exposed to heavy rain, humidity, or submersion.
- Water-resistant spray paint: Can handle light moisture but may not hold up under prolonged exposure to water.
For outdoor projects, always opt for weatherproof spray paint or waterproof outdoor spray paint to ensure long-lasting results.
Best Waterproof Spray Paint for Wood
Wood is a porous material that can absorb water, leading to warping, rot, and mold. To protect wooden surfaces, use a waterproof spray paint for wood or a water sealant spray paint. Some top options include:
- Rustoleum Painter’s Touch Ultra Cover: Provides a waterproof, durable finish for wood.
- Krylon COLORmaxx: Offers excellent adhesion and water resistance for wooden surfaces.
- Thompson’s Water Seal Clear Spray: A clear, waterproof sealant specifically designed for wood.
Best Waterproof Spray Paint for Plastic
Plastic surfaces can be tricky to paint because they are non-porous and prone to chipping. For the best results, use a waterproof spray paint for plastic that adheres well and provides a durable finish. Some top choices include:
- Krylon Fusion All-In-One: Designed specifically for plastic, it offers excellent adhesion and water resistance.
- Rustoleum Specialty Plastic Spray Paint: Provides a waterproof, durable finish for plastic surfaces.
- Valspar Plastic Spray Paint: A budget-friendly option with good water resistance.
Waterproof Clear Spray Paint
If you want to protect a painted surface without altering its color, waterproof clear spray paint is an excellent option. It adds a protective, waterproof layer that enhances durability and resistance to moisture. Some popular choices include:
- Rustoleum Clear Coat: Provides a waterproof, glossy finish.
- Krylon Clear Coat: Adds a durable, waterproof layer to painted surfaces.
- Minwax Polycrylic Protective Finish: A clear, waterproof sealant for wood and other surfaces.
Ingredients in Spray Paint
The ingredients in spray paint play a significant role in its waterproofing capabilities. Most spray paints contain:
- Pigments: Provide color and opacity.
- Binders: Hold the paint together and adhere it to the surface.
- Solvents: Help the paint spread evenly and evaporate as it dries.
- Propellants: Gases that push the paint out of the can.
For waterproof spray paints, the binders and additives are formulated to create a durable, water-resistant finish. Look for terms like acrylic enamel or polyurethane on the label, as these indicate a waterproof or water-resistant formula.
Oil-Based vs. Water-Based Spray Paint
When it comes to waterproofing, oil-based spray paint generally outperforms water-based spray paint. Oil-based paints create a harder, more durable finish that is better at repelling water. However, they also contain more VOCs and take longer to dry. Water-based paints are easier to clean up and more environmentally friendly but may require a clear waterproof topcoat for added protection.
How to Make Spray Paint Waterproof
If you’ve already used a non-waterproof spray paint and want to protect the surface, you can apply a waterproof clear coat or water sealant spray paint. This will add a protective layer that repels water and enhances durability.
