TOP of the best paints for metal for outdoor and indoor use

Metal is one of the most common and affordable building materials. It is often used for the manufacture of gates, fences, garages, and supporting structures. But among the many pluses, there is one significant minus. This material oxidizes and rusts in a humid environment. Better paints for metal create a durable protective film that can extend the life of sensitive structures.

Varieties of paints for metal

Nitrokraska (NTs)

They can be produced in the form of an aerosol in special cans, in the form of a solution or a dry mixture, which is diluted with any solvent. The advantages include low cost, quick drying, and the ability to remove with a solvent.

At the same time, the number of minuses clearly outweighs - this is poor adhesion to the base, which simply leads to shattering of the coating, great vulnerability to sunlight, high consumption per unit area, extremely pungent odor and high toxicity, which makes this composition practically inapplicable for interior work ...

Pentaphthalic (PF)

This type of paints and varnishes is universal, but at the same time it is not very suitable for use on metal, since it has a low level of adhesion to this material, to improve which special primers have to be used.

The paint dries very slowly and at low temperatures this process can take an infinitely long time. Under intense exposure to sunlight, the coating will fade quickly.

Rubber

Rubber paint is a more modern alternative to its ancestor, the famous bitumen paint, which was made from bitumen tar. She inherited all the unique qualities of her ancestor, but at the same time acquired a more neat appearance. This composition ideally insulates the metal surface from any mechanical damage and environmental influences, which virtually completely eliminates the possibility of corrosion.

Good adhesion allows this mixture to easily adhere to any surface with different coatings. However, the high price and sick expense slightly reduce its popularity.

Hammerheads

The composition of this paint includes polymer resins that have excellent adhesion to metal and form a very strong and durable coating that reliably protects it from corrosion. As can be judged from numerous photos, it is somewhat reminiscent of the prints of a large hammer in its texture, which explains the very unusual name.

This product is sold as a ready-made mixture, mainly in cans. It can be used without preliminary priming, since it itself is to some extent endowed with the qualities of a primer, filling in itself all small cracks and irregularities on the metal surface.

Polymer (blacksmith)

This product is ahead of all its competitors in all aspects, which it makes no sense to list, since they are much better than all previous products. This explains the high cost, which is quite justified, since the service life of such a coating is at least 20-30 years.

Blacksmith paint has one peculiarity, it should only be applied on a special primer designed exclusively for this type of paint.

Acrylic

Previously, such paints were not used to paint metal, they were used to paint mainly surfaces made of wood, concrete, drywall, brick and others. But later it turned out that they are ideal for metal. Such mixtures are made on the basis of an aqueous emulsion with the addition of polyacrylate, dyes and a special anti-corrosion additive.

Acrylic paints are absolutely non-toxic, completely odorless, and when applied, they form a strong and durable coating.They are well suited for painting heating devices due to their insensitivity to high temperatures, they have a large catalog of colors and shades.

Rating of the best paints

Hammerite

One-component acrylic enamel from Hammerite for anti-corrosion and decorative painting of surfaces, which has been breaking sales records all over the world for many years and effectively protects steel and cast iron surfaces.
