What Is The Best Paint For Metal Surfaces Outdoor And Indoor?

Paint is one of the best ways to protect metal surfaces from rust and other weather damage.

It can be used on both indoor and outdoor metals. Several types of paints – oil-based, water-based, acrylic, and enamel – are used in single or multiple layers. But what is the best paint or protectant for metal surfaces outdoors and indoors?

Rust-Oleum, Krylon color master, Behr pro-E600, and Rexpro metal sealers are the best paints and protectants for metal surfaces. You can use them both indoors and outdoors and they have better drying time and longevity. The painted surface can even withstand minor external abrasion.
Paint increases the longevity of metal surfaces by resisting corrosion. It also enhances the look and restores the original finish. Learn more below.

Best Paints For Metal Surfaces Outdoor And Indoor

Paints help keep metal surfaces secure and corrosion free. It prevents weather damage and helps it last longer than average. There are various types of paints on the market for metal surfaces, both indoor and outdoor such as oil-based, acrylic paint, latex paint, or spray paint. Don’t worry because we will show you the five best paints and protectants for metal surfaces on the market.

1. Rust-Oleum Protective Paint

Rust-Oleum helps protect metal surfaces from rust because of its corrosion-resistant formula. This paint is suitable for metal surfaces outdoors and indoors. The pigment is mainly oil-based, and it dries in about two hours. It can sustain extreme weather and says it can go up to 1200 degrees Fahrenheit. The protective layer is pretty durable. It can also withstand abrasion. The faster drying time gives you the ability to put the surface back into service relatively quickly.

2. Krylon Color Master

Krylon is an acrylic-based paint. It also integrates the process of painting and priming into a single easy process. It will save you time and effort to paint metal surfaces indoors and outdoors. It also comes in a variety of finishes and colors. The paint will dry in just 10 minutes. Such aquick dry time is pretty handy, especially when painting outdoor metal surfaces.

3. Behr Pro E600

Behr Pro E600 is one of the best oil-based acrylic paints for metal surfaces. You can directly apply it to metals and the paint will adhere to virtually any metal surface. You can also wash the painted surface with soap and water without degrading the look. It resists corrosion and other harsh materials outside. You can even do multiple layers to improve wear resistance.

4. Majic Paints Interior And Exterior

Majic Paint is a water-based paint with a stain finish. It requires only a single coat without priming or sanding. It’s a versatile paint because you can use it on outdoor and indoor metals, glass, wood, and other surfaces. This paint is also ideal for DIY projects. The paint dries in 8 hours. However, after such a long time, it will give a stained finish because of the enamel paint.

5. Rexpro Metal Sealer (Our Recommendation)

Rexpro provides a specialized metal sealer that can be applied directly to bare or painted metal. It is commonly used on heavy machinery, in marine environments and on transportation applications to prevent steel and other metals from rusting and oxidizing.
Perhaps most importantly it can be used over other paints to dramatically improve the longevity of metals that have already been painted. It will also add a shine to the painted metal and greatly improves abrasion resistance and UV breakdown of the paint beneath. On decorative metals such as copper which tend to oxidize it will prevent the green patina from forming keeping its bright orange luster for years.

Benefits Of Using Rexpro Metal Sealer and Painted Metal Sealers

Paint and sealers on metal surfaces have several benefits.

Paint and sealers on metal surfaces have several benefits. It would be wise to know the benefits if you want to protect your metals from rusting and to avoid changing them frequently. Here are the benefits:

Paint Longevity

A good quality metal paint will stay longer on the metal surface. As a result, you don’t need to go through the same hassle of painting the metal more frequently. You can also use metal sealers to indirectly protect paints and the metals.

Resists Wear And Corrosion

The main enemy of metal is rust and corrosion. But with a painted surface, the metals can’t get in contact with oxygen or water. When there’s no oxygen or water contact, there is no possibility of corrosion. So, paint can resist wear and corrosion. So, your metal surfaces, both outdoors and indoors, will stay last much longer.

Improves And Maintains Color

Frequent application of paint on metals will keep the surface looking fresh and new. The paint will fade over time. Using a metal sealer like RexPro will keep the paint looking better for longer.

It Makes The Surface Harder

Metal sealers can give the surface an extra layer of protection. That’s because it can harden the surface. So, the metals can easily resist minor external impact, chipping and abrasion.

Resists Salt And Other Chemicals

Sealers are made of particularly inert components. That’s why it doesn’t react with salt and other chemicals. Without chemical reactions, the metals won’t be damaged. So it will last longer than a typical unprotected metal.

Restores Shiny Look

The look of the metal surface degrades over time because of sun, salt, water and debris. But with the painted metal sealer, you can restore that shiny look.

Easy To Apply, Spray, Or Wipe

Most metal paints come in aerosol cans to provide even coverage. RexPro sealers can be sprayed, rolled or even wiped on to surfaces easily.

RexShield Metal

Can you use RexShield Metal to coat bolts to prevent rust?

Yes, steel bolts when exposed to air, salt or water over time will start to oxidize and rust. Once this happens it can become increasingly difficult to screw and unscrew the bolts. Even though repeated abrasion can wear down the RexShield coating the bolts will last much longer. RexShield Metal is a transparent penetrating sealer that prevents moisture and oxygen from coming in contact with the surface of the metal. This prevents rust and oxidation.

Will RexShield Metal prevent iron from rusting?

Yes, iron is highly susceptible to rusting and RexShield can greatly improve the longevity of iron. It does this by penetrating into the surface of iron so that it cannot oxidize.

What is the best paint to apply to metals to prevent rust?

There are a wide variety of paints used on metals to prevent rust. This includes enamels, organic paints, powder coatings and epoxies. Eventually, due to their surface bond most paints will wear down and degrade. One of the best paints to use on metal is a mineral based paint because they use silicates which have a longer life expectancy.

Can RexShield Metal be applied to painted metals?

Yes, RexShield Metal will improve the bond of paints to metal. It will also make them harder. For aesthetics it will restore the brilliance of a faded paint. There is some preparation required, such as a light abrasion with a scotch guard, or similar. Contact our technical staff for more information.

Can RexShield Metal be used as a rust prevention spray for metal?

Yes, RexShield Metal can be applied with a microfiber or sprayed with a variety of sprayers. The simplest way to spray it is with a pump sprayer but it can also be applied with an airless sprayer or HVLP. There is often less material waste when RexShield Metal is rolled or wiped on a surface but this is not always practical. Some metals like heavy machinery, tools, gears and other equipment do not have smooth surfaces. It is therefore much easier to just spray these surfaces. Be sure to spray from the bottom up and don’t overspray or you can get drips!
RexShield provides an extremely durable and corrosion resistant surface. This is a technology that has been used in the marine industry for over 75 years. By using RexShield you are providing your steel with long lasting protection against the elements.
