Stainless steel is a widely used material in households and commercial spaces. However, despite its durability, it may start to look old and fade after a while. There are different ways to maintain the quality and appearance of stainless steel, one of which is painting it. But which paint and primer is best?
For stainless steel, an oil-based metal paint is the best option. If you are concerned about rust, use paint that has rust-inhibiting properties. Using an oil-based metal primer before painting the stainless steel is recommended as it will help create an even layer of paint over the surface, increasing durability.
In this article, you will learn:
- The 4 factors to consider when choosing paint for stainless steel

The 4 Factors to Consider When Choosing Paint for Stainless Steel
1. Type of Environment
One of the most critical factors to consider when choosing paint for stainless steel is the type of environment in which it will be used.
For example, if the surface is exposed to saltwater, high humidity, or corrosive chemicals, it will need a more durable coating than in a dry, indoor environment.
Some types of paint are specifically designed for extreme weather conditions, while others are better suited for indoor applications.
2. Temperature Resistance
Stainless steel can endure high temperatures, making it ideal for manufacturing and food-grade applications. If you’re planning to paint stainless steel that will be exposed to high temperatures, you need to choose a heat-resistant paint.
3. Type of Paint
Not all paint types are suitable for use on stainless steel surfaces. Some types of paint may not adhere well to stainless steel’s slick, non-porous surface or may not be resistant to corrosion or fading. Generally, it’s best to choose a paint formulated specifically for use on metal surfaces, especially stainless steel.
4. Cost
Finally, you’ll need to consider the cost of the paint. While it’s important to choose a high-quality paint that will provide the level of protection you need, you also want to make sure you’re not overspending on a product that may be more than you need. Consider the size of the area you’ll be painting, the type of paint you’re using, and the application method.
What Type of Paint Is Best?
Oil-based Paint
Oil-based paint is a type of paint that uses oil as a carrier for the pigment. It’s highly regarded for its durability and rich finish.
Pros
- Excellent adhesion properties
- Resists chipping and wear
- Provides better coverage with fewer coats
- Dries into a smooth, glossy finish
Cons
- Takes longer to dry
- Cleanup requires solvents like mineral spirits or turpentine
- Emits strong fumes that require good ventilation
- Contains higher levels of volatile organic compounds (VOCs)
- May turn yellow
Acrylic Paint
Acrylic paint is a type of paint made of pigment suspended in an acrylic polymer emulsion. It’s water-soluble but becomes water-resistant when dry.
Pros
- Quick Drying
- Easy Cleanup
- Low Odor
- Contain fewer volatile organic compounds (VOCs)
Cons
- May not adhere as well to non-porous surfaces like stainless steel without proper surface preparation
- May not hold up as well in high-moisture or outdoor environments
- Can be sensitive to water
- May require multiple coats for desired opacity and finish
What Paint Finish Is Best?
When it comes to painting stainless steel, choosing the right finish is critical for both the visual appeal and the durability of the result. As a rule of thumb, the glossier the finish, the better the protection against damage, corrosion, and wear.
High-gloss finishes, such as gloss enamel or high-gloss epoxy, are particularly resistant to abrasion, moisture, and chemical substances, making them ideal for stainless steel surfaces exposed to frequent use and harsh environments.
Moreover, glossy coatings form a smooth and non-porous barrier that prevents dirt, grease, and bacteria from adhering to the surface, thus ensuring easier cleaning and maintenance.
Other paint finishes that can be used for stainless steel include satin and semi-gloss. Satin finishes, also known as eggshell or low-sheen, have a subtle shine and a smooth texture that result in a sophisticated look and moderate durability.
Semi-gloss finishes offer a good balance between visual appeal and protection, making them suitable for both interior and exterior applications. As with glossy coatings, semi-gloss paints should be applied in multiple coats to ensure durability and coverage.
