Is Rustoleum Spray Paint Waterproof? The Science Behind it

As a premium paint brand, Rust-Oleum spray paints are formulated with the finest ingredients. It was originally made with fish oil which naturally protects against rust and corrosion. In its early years of conception, fish and whale oil were the primary ingredients used to make most Rust-Oleum paints. 

Over the years, however, the company has incorporated other innovative approaches into its formulations. Today, oil-based rust-oleum paints no longer contain fish oil but are primarily made with petroleum, petroleum distillates, and acetone. The products also contain epoxies, latex, polyurethane, and resins extracted from alkyds.

Furthermore, the Rust-Oleum company originally specialized in oil-based paints but has since included acrylic and water-based paint options. Rustoleum oil-based paints provide superior durability and adhesion for any material and surface. 

These premium ingredients make Rust-Oleum spray paint highly resistant to water. However, it’s best always to check the product label to know if the spray paint is oil- or water-based. 

Oil-based spray paints have a lot more immense benefits than water-based paints. For example, they provide better adhesion and coverage. Oil-based paints are also less prone to chipping and peeling and can withstand weather conditions well. 

They’re more suitable for outdoor use or projects that require maximum durability. However, oil-based spray paints also contain strong odors. 

Therefore, they are highly flammable compared to water-based options, which largely contain water and pigments, making them less volatile, less durable, and easy to clean. 

How to Spray Paint a Surface with Waterproof Rustoleum Spray Paint?

If you want to use Rust-Oleum spray paint, it’s best to follow a proven procedure that will retain the paint’s quality and offer superior protection against water. Below is a straightforward step-by-step process for spray painting a surface with Rust-Oleum spray paint. 

Some materials you’ll need include Rust-Oleum Spray Paint of your choice, old newspapers, drop cloth or duct sheets, and masking tape. The process is as follows:

1. Organize Everything Together

Before you get the ground running with your project, ensure you have everything you need in one place. These include a drop cloth or old newspapers to spread on your workspace and trap those stray spills. 

You should also wear safety equipment like a face mask, eye goggles, and paint gloves. If you need to mask away specific surfaces or items, include masking tape and painter’s tape in your list. 

Finally, get the right waterproof spray paint of your choice and ensure the can nozzle and other components are in perfect working condition. 

2. Choose a Good Paint for the Job 

As high-end as Rust-Oleum is, not all its spray paints are the same. Most spray paints are compatible with nearly every surface, but some are better suited for specific surfaces than others. Therefore ensure you get the right spray paint for the project you are working on. 

3. Prepare the Substrate for Painting 

Ensure that the object you want to paint is clear of any dirt or surface impurities before applying the first coat. Depending on what you’re painting, consider priming to enhance paint adhesion. 

To do this, test the paint on a particular spot to ensure it’s compatible with your object. If it demonstrates excellent adhesion, you need to prime the surface. 

But if the paint doesn’t stick well enough, consider priming with Rust-Oleum Surface Primer before painting. However, using Rust-Oleum Universal priming is not necessary. 

4. Shake the Can Well

Before applying the first coat, thoroughly shake the can to mix the paint evenly. This helps blend the solvents and pigments to create a consistent formula that will guarantee a smooth finish. 

5. Keep Your Workspace Well-ventilated 

If proper safety isn’t observed, working with oil-based spray paints can have some negative health effects. Most of these spray paints have toxic compounds that may be harmful if inhaled. You want to protect yourself from such effects but ensure your workspace has sufficient airflow. 

It’s best to spray paint outdoors where you’ll have an oversupply of fresh air, but keep the windows and doors open if you must work indoors. You might even want to turn on the fan for maximum air circulation. 

6. Test the Paint 

To be sure your project will turn out as expected, consider testing the paint on an inconspicuous spot or object before you start working. 

Use this step to determine the proper spraying distance, the number of coats needed, and whether or not you should adjust the color of your paint.

7. Start with the Edges

It’s always good to start with the edges when painting a large surface. By tackling the edges before the center of the object, you’ll be able to prevent paint runs and drips and maintain a seamless, consistent process. 

8. Apply Even Coats

Light, even coasts, are known to yield the best results than thick ones. Avoid applying too much paint on a single spot to prevent inconsistency. With each coat, wait for the time specified on the product before recoating. 

We also recommend that you pause to shake the can at various intervals during the painting session to maintain the consistency of the paint. This will also help to unclog the spray paint can for even paint discharge.

A better approach is to slightly overlap each stroke, moving back and forth, up and down, to prevent paint stripping and achieve a balanced, smooth finish. 

Is Rustoleum Spray Paint Waterproof After Drying?

Like most spray paints, Rustoleum is a liquid coating solution. That means it can get ruined if mixed with or submerged in water in its liquid form. However, once it’s been sprayed and the pigments and solvents have hardened, it easily resists water. 

In other words, Rust-Oleum is waterproof after drying, but it’s not 100% resistant to water when wet. A few factors affect Rust-Oleum waterproof capabilities; for example:

  • Paint quality: Water-based Rust-Oleum spray paints do not offer the same durability and protection as oil-based paints. They’re easily susceptible to overexposure to moisture, so it’s best to use oil-based paints on outdoor surfaces that require high durability. 

  • Surface types: Sealing porous surfaces is a great idea to achieve maximum resistance to water.

Do You Need to Seal Rustoleum Spray Paint?

No. Sealing Rust-Oleum spray paint is not necessary. As a premium paint, Rust-Oleum is formulated to dry perfectly and provide a durable finish without additional recoating or sealing. 

The paint is waterproof and corrosion-resistant and bonds well with most surfaces rendering sealing (and in some cases priming) entirely unnecessary. 

However, if you’re painting something that will be exposed to water for longer periods, such as a boat, you should add an extra layer of protection by sealing the final coat of paint. 

A good quality sealant or varnish is recommended for such cases to provide superior protection from peeling. 

Does Rustoleum Spray Paint Come Off in Water?

If the spray paint is still wet, it will come off if submerged in water since it’s not properly hardened. Such spray paints tends to wipe away easily. However, once the binding agents in Rust-Oleum spray paint harden, the paint becomes highly waterproof. This is true with all oil-based paints that have fully dried and cured. 

Such paint can be difficult to remove since they contain naturally waterproof alkyd binding agents. If you need to clean or remove such paints, you’ll need to scrub vigorously with dish soap and lots of water. 

Removing dried Rust-Oleum spray paint on porous surfaces is even more challenging, and you might need a power washer or heavy-duty cleaning solutions to remove them.Β 

How Long Does it Take for Rustoleum Spray Paint to Dry?

Most Rust-Oleum spray paints dries to the touch in 20-30 minutes. Others are designed to dry within an hour before recoating. At best, paint should be left to dry for at least two hours. 

However, Rust-Oleum recommends leaving your painted project to sit for 24 hours to allow the paint to dry and cure optimally. That’s enough time to ensure the paint is 100% waterproof. 

To speed up the process, apply thin coats, and if it’s urgent, a dehumidifier or space heater could help. Always spray paint within 65 and 85 degrees F temperatures to make the paint dry faster.

FAQS: Is Rustoleum Spray Paint Waterproof?

Is Rustoleum spray paint water-resistant?

Yes. Rust-Oleum spray paints are made with natural oil and alkyd binding properties that ensure the paint can withstand maximum contact with water.

What happens if spray paint gets wet?

If your spray paint comes into contact with water or moisture before it’s dry and cured, it will likely wipe away easily and dissolve in water. However, dried spray paint is generally waterproof. Such pants can resist rain, snow, and other harsh elements, although water-based spray paint has less waterproof capabilities than oil-based paint. 

Is Rustoleum paint weather resistant?

Yes, rustoleum is a water-resistant spray paint. Made with the finest ingredients, Rust-Oleum spray paint is a premium product designed to endure all the natural effects of weather. As the name implies, Rust-Oleum can resist rust and corrosion, the primary effects of weather. They can also withstand excess moisture, U.V. lights, or wind. They’re exterior spray paint, meaning they’re made to survive the effects of wear and tear, so they’re best suited for outdoor use. 

Is the spray paint waterproof?

Yes. Oil-based Rust-Oleum spray paint is waterproof when fully dry. Your spray paint should be able to retain its original quality and shine if exposed to water after drying. However, you should ensure the spray paint doesn’t come into contact with water before it’s fully cured since it could wash off, especially if it’s water-based spray paint. 

Do you need to seal Rustoleum spray paint?

No. You don’t need to seal Rust-Oleum spray paint after painting. The premium paint contains high-quality bonding and sealing agents for superior protection. Unless it’s water-based paint or a heavy-use environment, you don’t need to seal your project painted with Rust-Oleum. However, this largely boils down to preference. If you wish to add a new coat of varnish or sealant to your surface for extra sheen and protection, you can do it out of choice, not necessity. 

In Summary: Is Rustoleum Spray Paint Waterproof?

Yes, Rust-Oleum spray paints can be oil-based or water-based. The oil-based options are 100% waterproof, containing powerful binding agents and ingredients to guarantee a long-lasting finish.
