Rust-Oleum offers a range of products that can seal and protect metal surfaces from corrosion and moisture. For example, the Rust-Oleum Stops Rust range provides spray paint and brush-on paint that can defend outdoor metal objects against rust and corrosion. However, it is unclear if Rust-Oleum paint seals in moisture on steel. To answer this question, we must first understand the preparation and priming process required before applying paint to rusty metal surfaces, as well as the specific properties of Rust-Oleum's paint products.

Rust-Oleum's 2-in-1 Rust Reform & Seal
The Rust Reform & Seal paint is part of Rust-Oleum's range of products aimed at protecting metal surfaces against rust. For instance, the Stops Rust Protective Enamel spray paint can be used on a variety of objects, offering long-lasting results and coming in over 50 popular colours and four finishes (gloss, semi-gloss, satin, and flat). Before applying spray paint, it is recommended to use a primer, such as the Stops Rust Clean Metal Primer for uncoated metal or the Stops Rust Rusty Metal Primer for heavily rusted surfaces.
In addition to spray paint, Rust-Oleum offers a range of other products to prepare and protect surfaces. These include traditional, specialty, and spray primers, household cleaners, and professional cleaning solutions. For high-traffic areas, the Modified Urethane Latex Epoxy coating is a good option as it is abrasion-resistant.
Rust-Oleum also offers solutions for specific types of surfaces, such as their DIY epoxy garage floor kit, which seals and protects garage floors, and their Industrial Choice 1600 Multi-Purpose Spray Paint, which is a popular choice for professionals. With such a wide range of products, Rust-Oleum gives users the power to enhance or protect nearly any surface, from metal to wood to concrete.

Rust-Oleum's Stops Rust range
The Stops Rust spray paint and brush-on paint are designed to defend outdoor objects and a wide variety of surfaces against the elements, including rust. It is available in over 50 popular colours and four finishes: gloss, semi-gloss, satin, and flat. The Protective Enamel with Custom Spray 5-in-1 offers five different spray paint patterns in a single dial, allowing you to select the most suitable output for your project.
For surfaces that are heavily rusted, the Stops Rust Rusty Metal Primer can be applied before painting to create a paintable surface. The Rust Reformer can also be used on heavily rusted metal, bonding directly to rust and creating a durable, flat black finish without the need for sanding or stripping.
To prepare metal surfaces for painting, the Stops Rust range offers different types of primers depending on the surface. For uncoated metal, the Clean Metal Primer can be used, while the Universal Bonding Primer is suitable for difficult-to-adhere surfaces. The range also includes the 2-in-1 Rust Reform & Seal, a flexible, rubberized paint that seals rust and protects metal surfaces from corrosion and moisture. It provides a chemical and abrasion-resistant barrier, making it ideal for cars, trucks, trailers, and other recreational vehicles.

Priming steel before painting
There are different types of primers available, and the selection depends on the type of metal, surface condition, and paint used. For steel, common primers include etching primers, acrylic primers, rust-inhibitive primers, and epoxy primers. Etching primers are ideal for non-ferrous metals like galvanised steel, while acrylic primers are suitable for interior steel surfaces with minimal exposure to harsh conditions. Rust-inhibitive primers, such as the Rust-Oleum Rust Reformer, are recommended for rusted steel surfaces, converting them into non-rusting, paintable surfaces. Epoxy primers, known for their strong adhesion and chemical resistance, are versatile and can be used on various metals, including steel.
Before priming, it is essential to prepare the steel surface. This includes cleaning the surface with mineral spirits to remove grease and dust, sanding the area to smoothen it, and addressing any rust or corrosion. If the steel surface is new, a simple cleaning and sanding may suffice. However, if there is rust, it must be removed by brushing off loose rust, sanding, and then applying a rust-inhibitive primer.
After priming, you can proceed with the painting process. It is important to follow the manufacturer's instructions for the specific primer and paint products used. Ensure that you allow adequate drying time between coats and provide proper ventilation during application.
By following these steps and properly priming the steel before painting, you will achieve a high-quality, long-lasting finish that protects the steel surface from corrosion and enhances its appearance.

Using a water-based primer
Rust-Oleum offers a range of products to protect metal surfaces from corrosion and seal in moisture. One such product is the Rust-Oleum® 2-in-1 Rust Reform & Seal, which is a flexible, rubberized paint that seals rust and protects metal surfaces from corrosion and moisture.
Now, when it comes to using a water-based primer on steel, there are a few important considerations to keep in mind. Firstly, it is crucial to ensure that the water-based primer is specifically designed for adhesion to metal. Some primers may not be suitable for steel, so checking the manufacturer's instructions is essential. Additionally, proper surface preparation is critical. The substrate should be thoroughly cleaned and, if necessary, treated with a rust converter to prevent rust bleeding through the primer. It is also important to note that oil-based contaminants on the steel surface can interfere with the adhesion of water-based primers, so it is crucial to remove any oil residue with a suitable solvent, such as lacquer thinner.
Another consideration is the environmental conditions during application. Water-based coatings may not dry properly in cold temperatures, resulting in a sticky film known as a cold cure. Therefore, it is important to ensure that the steel surface is not too cold, even if the surrounding air temperature is within an acceptable range. Additionally, humidity can also affect the performance of water-based primers, as higher humidity may impact the drying process and the final finish.
It is worth noting that while water-based primers are more environmentally friendly and have lower VOC (volatile organic compound) levels than oil-based alternatives, they may have a shorter shelf life. Therefore, it is essential to follow the manufacturer's guidelines regarding the lifespan of the primer in liquid form.
In conclusion, when using a water-based primer on steel, it is crucial to select a primer suitable for metal adhesion, ensure proper surface preparation, address any oil-based contaminants, consider environmental factors, and be mindful of the product's shelf life. By following these steps, you can effectively use a water-based primer on steel and benefit from its advantages, including enhanced adhesion, a smoother finish, and environmental consciousness.

Rust-Oleum's Moisture Stop Fortifying Sealer
The application process is straightforward and simple. Users are instructed to apply the sealer and let it penetrate the surface for approximately 45 minutes, with each gallon covering up to 200 square feet. While some customers have reported positive experiences, with the product effectively solving their moisture problems, others have expressed that it did not work for them, even after following the instructions carefully.
It is recommended to always test for moisture before applying any coating and to perform the moisture test again after using Moisture Stop. This product is available for purchase at various retailers, including Amazon and Home Depot, and comes in a 1-gallon container.
While Rust-Oleum does offer a range of products to protect metal surfaces from corrosion and moisture, such as the 2-in-1 Rust Reform & Seal, the Moisture Stop Fortifying Sealer is specifically designed for concrete floors and may not be the most suitable option for sealing in moisture on steel.

Frequently asked questions
Rust-Oleum® Stops Rust® spray paint and brush-on paint defend metal surfaces against rust and corrosion. It is not clear whether this paint seals in moisture, but given that it protects against rust and corrosion, it likely seals in moisture to some extent.
First, remove as much loose rust as possible from the steel surface using a wire brush or sandpaper. Then, remove any remaining grit, grime, and grease with a soft cloth dampened with a mixture of liquid dish soap and warm water. Allow the steel to air-dry completely before applying a primer.
You can use either a water-based or oil-based interior-exterior rust conversion metal primer.
