Rust paint for exterior metal work as a way to protect material
Metal is often used as a material for the manufacture and finishing of many objects. Due to its specific properties and characteristics, it is very much in demand when it comes to structures operated in outdoor conditions. The same features cause the need for the use of paints and varnishes. They prevent premature deterioration of metal products under the influence of external factors.
Metal structures that are used as elements of the facade of the building and need additional protection:
- water pipes;
- elements of the heating system;
- fences on stairways and balconies.
In suburban construction metal structures are used very widely. This type of material is used for the manufacture of gates, greenhouses, arbors, trellises and small architectural forms. Depending on the type of metal, the surface may have different characteristics. Among them, strength, resistance to high temperatures, etc. Despite the numerous advantages of the metal, there are drawbacks that force the use of anti-rust paint for exterior works.
The main disadvantage of the metal is its vulnerability to the effects of corrosion, which affects the appearance of products and their operational life.
Interesting fact! Rust is the result of oxidation that occurs on the surface of the metal. The appearance of corrosion is not provoked by the moisture itself, air is also involved in this process. More precisely, the destruction of the metal occurs when the air contains a large amount of water vapor.
As the formation of corrosion penetrates into the material. It provokes the accumulation of moisture in the metal due to its porous structure. The simplest way to protect the material is to use a corrosion-resistant primer in combination with a dye. But such an approach is costly in terms of material means and time.
The best option for protection will be the application of paint on metal and rust for exterior work, which will form a barrier that prevents the occurrence of oxidative processes.
The main methods of protecting metal products from rust:
- Galvanic tread.
- Cold galvanized.
- Phosphating (corrosion conversion method).
- Cupping with a polymer film.
Dyes for finishing metal surfaces and compositions rust are divided into the following types:
- acrylic water dispersion;
- alkyd on metal and rust;
Alkyd dyes designed for metal and rust, are characterized by good adhesive properties. The cost of most of these compounds is low. Some types of products are designed to finish galvanized and non-galvanized metal surfaces damaged by rust. It does not require pre-priming.
Acrylic polymers are used as the basis for the manufacture of acrylic paints for metal for outdoor use. Their structure includes modifying, anti-corrosion elements. Working with such material is very comfortable, as it does not have an unpleasant smell. Manufacturers recommend treating the metal with a primer before applying wear-resistant acrylic dyes.
To buy a polyurethane paint for metal will have to spend. Typically, these paints are used for finishing metal surfaces indoors. The coating has a silky surface, which is resistant to chemical factors and mechanical damage. Therefore, in some cases, they can be used outside.
Hammer dyes with anti-corrosion properties can be applied over rust. These compounds form on the surface of the coating in the form of hammer embossing. They provide reliable and effective protection against corrosion.
Note! Experts recommend using hammer type paint as a finish for ferrous metals. It is this kind of paint that is best suited for this purpose.
The impact of atmospheric factors has a negative effect not only on metal, but also on wooden surfaces. Of course, wood is not prone to corrosion, but it can be susceptible to fungi, delamination and deterioration by insects. Therefore, such products also need protection.
Decorative characteristics of the hammer black paint on metal for outdoor work just at the height. But is this type of finishing material suitable for wood? Hammeraite paint is optimal for both metal and wood products. Moreover, the use of rust is allowed, as well as application to a previously painted surface.
The technology of preparation of the tree and its coloring practically does not differ from the work performed with a metal base. However, there are certain nuances. Cleaning of the exfoliating paint and varnish covering has to be carried out by the sparing methods. For these purposes, it is better to use sandpaper. Treat the surface very carefully so as not to damage the material.
The use of metal brushes must be abandoned. Wood is soft, and a metal brush can damage the surface and leave deep scratches on it. After the product is cleaned, the base is thoroughly washed and dried. It is necessary to start applying paint only after the wood has completely dried and a preparatory layer has been applied.
Important! Before dyeing with Hammeraite, after stripping the wood, the unprotected areas of the material must be treated with a special primer compound that prevents the development of mold and fungus. The manufacturer recommends the use of primer composition No. 1 Rust-Beater.
The palette of shades of dyes intended for exterior work is not as wide as that of the compositions for interior decoration, however the choice of colors is significant. Consumers can purchase acrylic paint on metal for exterior work with a semi-gloss, matte, semi-gloss and glossy surface.
Ships are made of different materials: for some elements of the transport metal is used, for others – wood. Given the aggressive effects of environmental factors, both of these materials need increased protection. Some parts of the ships are constantly in contact with water, which may include salt (sea water), and the wood is exposed not only to moisture, but also to the wind, direct sunlight.
The modern range of dyes is represented by antifouling and anti-corrosion compounds. The most popular materials are Tikkurila Panssarimaali, Politax and International Paint Interdeck. All of them are suitable for operation in a humid climate and for the finishing of industrial structures. They are used to process steel, aluminum, duralumin coatings.

To find out the opinion of consumers about Hammerite dye, just look at the comments of customers on the forums:
“I heard about the paint Hammerayt on metal and rust, unflattering reviews. One buyer complained that the coating peeled off a year later, but among my friends who used this material, there were no complaints. Therefore, I decided to trust the opinion of people I know personally. And no mistake. The covering has perfectly laid down on a fence and already one and a half year looks like new. Perhaps people who have had a negative experience with Hammerite, violated the technology or did not clean the surface from rust. After all, on a thin layer the material will last, but thick layers should be removed. Information is on the package, so I don’t know why there are problems. ”
Sergey Skorik, Yekaterinburg
“I have been working with dyes for several years. As a professional, I can say that the paint Hammerayt is no better than others, but no worse. With proper preparation and use of the recommended funds, the coating is of high quality. This requirement applies to all dyes. Tested in practice. “
Anton Pankov, St. Petersburg
“I worked the walls of the garage from the inside with Hammeraite. I was pleased with the result. But in the open air dye disappoint. ”

Depending on how the film coating is formed, the range of powder dyes for exterior work is divided into two types of compositions: thermoplastic and thermosetting.
The first type of dyes contains plastic film-forming agents. The coating is formed in two stages. At first particles of the painting pigments fuse, and then are exposed to cooling. It does not require complex chemical reactions. As a result, the composition of the dye does not change at all and remains the original.
The process of baking thermosetting powders of the powder type, on the contrary, is accompanied by complex chemical processes. As a result, the initial molecular composition of the components changes. This type of coating has a higher strength, because the finish does not dissolve and does not melt.
Most often, polyurethane and polyester dyes are used for finishing products used outside. The average consumption of powder paint per 1 m2 on metal reaches 100-125 g / m ?.
Polyester types of paints are resistant to atmospheric and mechanical factors. Most often they are used as a finishing coating for products made of aluminum or steel.
The scope of their application extends to the following objects:
- elements of facade structures;
- roofing materials;
- details of window constructions;
- agricultural machinery;
- metal elements of cars.
Polyurethane powder dyes have a beautiful texture and lasting shine. They are used for processing tanks where reagents are stored, as well as for dyeing chemical equipment. Especially beneficial properties of polyurethane paints for surfaces that are subject to abrasive wear in intensive mode and mechanical loads.
