Paint for galvanized metal for outdoor works: types and features

In modern construction, galvanized metal is used quite often. It became popular due to its reliability and practicality. But the zinc coating has its drawbacks, expressed in a low resistance to corrosion. The material though is not as much exposed to this effect as steel, but if you want to achieve long-term operation, it should be covered with a special paint.

The main types of paint are galvanized

If you need paint for galvanized metal for outdoor work, then you need to deal with some varieties of such coatings. They are:

• Acrylic;
• Vinyl;
• Alkyd;
• Rubber.

Acrylics are usually made on the basis of organic solvents, on the sale can also be found water-dispersion compositions. Among the ingredients they contain anti-corrosion additives. Using acrylic paint and varnish materials, it is possible to create a matte layer on the surface. The main advantages of these mixtures are: excellent resistance to external influences, ultraviolet, excellent adhesion, excellent water-repellent properties, durability and low cost.

Overview of the features of alkyd paints for galvanizing

The paint for galvanized metal for outdoor work can be alkyd. If you compare with the above material, then with the help of the first one you can create a glossy coating. In the manufacturing process, an anticorrosive active pigment is used. Among other things, these paints have outstanding performance. In a wide range of modern markets, alkyd compounds can be found that can be used in industrial environments and marine climates.

Overview of the features of vinyl paintwork for galvanizing

Paint for galvanized metal for outdoor work can also be vinyl. Recently, it began to gain popularity, which is due to some of its properties. The paint has high weather resistance and copes well with the effects of high temperatures.

On the surface covered with a material, the temperature can be constantly influenced up to 70 ° C, temporarily the temperature can be increased to 90 ° C. However, the vinyl cover also has some disadvantages, which are expressed in high cost. The price is justified by some positive qualities in terms of durability.

Overview of the features of rubber paint on galvanizing

The paint for galvanized metal for outdoor works is also presented with a rubber coating, which is made on the basis of acrylic. Among the distinguishing features - high elasticity. After drying, the top layer of such a material will resemble rubber, thanks to this is not terrible impact on the surface of mechanical forces, such as bumps.

Such paints for metal surfaces are distinguished by their durability, chemical resistance, excellent weathering, environmental friendliness and high decorative properties.

Than to paint a roof from the zinced metal

If you need paint for galvanized iron than paint the roof, you should think about it. The most common coatings today can be called: acrylic dye, oil paints, as well as compositions with anti-corrosion properties. For such surfaces, special dyes should be used for the reason that in galvanizing the surface is more passive than conventional metal. Therefore, the paint should be chosen taking into account the high elasticity.

When choosing a paint on galvanized surfaces, experts advise to pay attention to the acrylic matt dye "Cicrol", which has high adhesive properties and excellent anticorrosion properties. Among the advantages of this paint and varnish material are: resistance to atmospheric influences, excellent tolerance of low temperatures and moisture resistance. This paint after drying quickly enough, under the influence of ultraviolet does not burn out and has water-repellent properties. Apply it to a dry and clean surface with a sprayer, roller or brush. If necessary, the composition can be diluted with a solvent P646 or butyl acetate. Such a protective coating significantly extends the life of the galvanized roof.

Reviews of the paint "Circle"

This anticorrosive paint for galvanized metal is a primer enamel, which is made on the basis of acrylic resins and polymer additives. As additional elements are organic solvents. According to customers, this mixture has a high hiding power of the surface to be painted.

Protect the mixture will be able even from exposure to salty air. Consumers emphasize that this primer is easy to use, has hydrophobic characteristics and is suitable not only for galvanized steel, but also drainage systems, gutters, galvanized pipes, profile, corrugated board, iron and galvanized iron.

The application of the mixture should be carried out on a surface that has been cleaned from rust, and xylene or ethyl acetate may be used as solvents if necessary.

Consumers are advised to work at a temperature range of -10 to +50 ° C. Full drying should wait for 18 hours, this is true if the temperature of the outside air is + 20 ° C.

Conclusion

The application of a special paint and varnish coating on the galvanized surface will protect it from the negative impact of the external environment. However, to begin these manipulations experts recommend only a year after the completion of the installation of roofing structures.

During this time, the atmosphere will prepare the substrate for staining, cleanse the rust and make the surface a bit rough. If you want to do work in a short time, then you can prepare the surface yourself, but in this case, you should try not to spoil a thin layer of galvanizing.
