How to apply hammer paint on metal?

Acrylic and water-based paints are widely known to consumers. Many people have enough experience to apply them without paying too much attention to the manufacturer's instructions. But the same cannot be said about hammer paint, although its merits are not in doubt. In some cases, only such a coating has to be used.

Hammer paint is intended for painting rusty surfaces. The presence or absence of the original layer of another paint, as well as the performance of external or internal work, does not matter. In all cases, the dye composition shows itself with dignity and quality. It got its name from the external appearance of the applied coating. It seems to be made of metal that has been hand-minted with a blacksmith's hammer.

Initially, hammer paints were used to cover industrial and laboratory equipment, for which external beauty is less important than service life. Until recently, no other hammer paint colors (except gray) were produced.

It is capable of masking significant surface differences and can also be used for re-painting. In recent years, technologists have corrected the flaw of their predecessors, and now this material is made in a variety of colors and shades.

Hammer paints for metal are formed by a combination of acrylic, epoxy and alkyd-styrene substances. To bind them together, finely crushed glass and aluminum powder are used. The liquid dye has a high level of adhesion. As soon as it hardens, the strongest protective layer appears on the metal surface.

The introduction of metallic powders increases the strength of the paintwork, but makes this mixture unsuitable for spray application. We'll have to work by hand (with a brush). Modern examples of hammer paints contain various types of colored dyes.

This material is very resistant to temperature extremes, so it can be used safely up to 80 degrees Celsius. There is no need to scrupulously clean and prime a rusty surface (while other varnishes, paints and enamels necessarily require such preparation, but even with its careful execution, they do not always fit well and stably).

The painting process is very simple and easy, and the painted layer is not sticky.

Even vibration will not be able to destroy its layer, and the anti-corrosion properties remain for at least 6-7 years. Hammer paint is safe for humans... If she tints the defects of the main coating, the difference in their tone will be barely noticeable.

To realize all the positive aspects of hammer paint, it is required to paint correctly:

• It is recommended to apply it with a horizontal arrangement of surfaces, otherwise the liquid will drain, and an attractive pebbled effect cannot be achieved at all.
• In cases where it is impossible to put the object to be painted, it will be necessary to use the compositions with the fastest drying. They will not have time to create ugly streaks before they dry.

• Remove factory grease before painting new metal to expose the actual surface of the structure. This requirement must be met, regardless of the type of dye.

• ML-165 is a heat-resistant hammer paint with excellent adhesion to the surface. It is recommended to apply it where the metal can warm up to 130 degrees. There are other types of coverage. Each has its own specific characteristics.

• Standard paint brushes and rollers will not work with this compound. It is necessary to use tools of a special design. If the substrate is very smooth and polished to a high shine, it may need to be brushed over with a metal brush or emery paper to improve grip.

• Try to remove peeling rust in advance (the coating will lie flat only on a uniform surface). You need to clean this dirt with an angle grinder, or with a drill, which are supplemented with metal brushes.

• Powder coatings that are unsuitable for hammer paint can be removed if they are burned out or treated with special solvents.
• After preparing the base with aerosol cans, hammer paint is applied to minor flat structures. And if the geometric shape is more complicated, you need to choose a brush - it is with it that benches and complex welded products are painted. Always use only diluents recommended by the manufacturer.
