Changes in tone after painting the surface - therefore, it is important to choose the right dye.
Difficulty sanding - after this manipulation, the coating does not look very attractive.
Fast Soiling - Matte backgrounds get dirty faster than glossy surfaces. After using such a dye, the surface will have to be cleaned more often.

Black color has an important drawback - it attracts ultraviolet radiation. The fact is that such a shade has a weak ability to reflect color.

How to use

In order for the application of the dye to be successful, it is important to follow a number of recommendations. In this case, it is important to properly prepare for the application of the substance.

Preparatory work

Before starting work, you need to prepare a number of materials. These include the following:

• primer;
• masking tape;
• respirator - helps to protect the respiratory organs;
• gloves - provide protection of the skin from the ingress of dye;
• rag;
• paper, newspaper or oilcloth - used to prevent dye from getting into unnecessary places.

Before using the dye, you need to equip the workplace. In this case, it is recommended to cover the places that should remain unpainted with paper or oilcloth. Then it is worth preparing the surface for applying the substance. To do this, it is recommended to do the following:

1. Remove the old coating from the surface.
2. Clean material from dust, dirt, rust. The cleaner the coating is, the better the hitch will be. If you cannot remove dirt with a damp cloth, you should use household chemicals.
3. It is recommended to sand the polished surface with sandpaper. It will give the material a certain roughness. The use of sandpaper improves adhesion.
4. Paste the borders of the area to which the dye is to be applied with masking tape. It should be fixed carefully to prevent paint bleeding.
5. Apply a primer to the surface. When choosing it, it is worth considering the type of paint and the base material.

It is important to take into account that it is permissible to apply paint and varnish only after the primer layer has completely dried.

Dyeing

For painting work, it is recommended to do the following:

1. Wear a respirator, goggles, gloves.
2. Shake the can to obtain an even texture.
3. Apply a test coat of paint to the rough surface. A piece of metal or an unnecessary board is suitable for this. This procedure will help you evaluate the quality of the spray pattern.
4. Apply the first coat of paint to the primer. At the same time, keep the can at a distance of about 20 centimeters from the surface. Displacing the torch is slow. The dye layer should not be very thick.
5. Wait for the coating to dry. This usually takes a day. After that, it is permissible to apply a second layer.

If the substance is used for outdoor work, it is permissible to paint the surfaces only in dry and warm weather. Otherwise, it will not be possible to achieve a good grip.

Completion

After painting the surface, it is important to wait until it is completely dry. This usually takes 1 day.

However, a specific period is indicated in the instructions for a specific dye.

Advantages and disadvantages

Matt black paint has many advantages:

1. Versatility (paintwork materials can be used to paint a wide variety of products, including cars and plastic products).
2. Ease of application.
3. The particles are well sprayed, unlike many other paints, where the same effect can be achieved only with the help of expensive professional equipment.
4. Resistant to ultraviolet radiation, due to which the surface retains a rich color even after many years.
5. Heat resistance.
6. Resistant to moisture and other environmental factors.
7. Low cost.
8. Non-toxic (this still does not mean abandoning safety measures when applying paint).
9. When sprayed, no solvent is required to achieve the desired viscosity.
10. Fast drying.
11. The black color emphasizes the shape of the object well.
12. The matt black color makes mechanical damage and dirt less visible.

There are relatively few downsides to matte paint, but they are still there:

1. The cost of painting services is quite high. But even if you do the work yourself, painting will not be cheap.
2. Matte coatings often change their tone after being applied to the surface. Therefore, choosing the right paint is a very demanding task that requires experience.
3. The matte finish is difficult to sand. After sanding, the surface usually does not look very attractive.
4. Matte backgrounds, as opposed to glossy ones, get dirty easily. This surface will have to be cleaned more often. In addition, mud stains always stand out against a matte background, which does not add attractiveness to a painted product.
5. Black itself also has a drawback - it attracts the sun's rays, since the reflectivity of this color is very weak. All things being equal, a black car will always be hotter than a white or red one.

Types of paints for metal

Paints are classified according to composition, purpose and properties. For metal, not only specialized coatings are suitable, but also some universal ones, which can also be used for painting wood, concrete and other types of surfaces. The basis for the manufacture of the coating is of paramount importance - it determines the strength, durability and heat resistance of the composition.

The composition of the following types of paints is distinguished:

• Epoxy. They are extremely toxic, therefore they are not used for internal work. Produced on the basis of silicone resins with a hardener. The coating withstands high temperatures well.
• Oil. Less toxic. The composition is based on natural oils or drying oil. They are used for interior work, as they are unstable to large temperature ranges. Not able to protect metal from corrosion. Therefore, the surface to be painted must be primed.
• Alkyd. They have a low level of toxicity. Used for interior work. They adhere well to the surface even without priming. Cannot withstand strong heating, combustible.
• Acrylic. Non-toxic, odorless. Produced on the basis of polymers. Diluted with water. Versatile in application. Suitable for painting parts that are exposed to heat. Provides protection against corrosion.
• Rubber. These paints are ideal for metal roofs. Toxic, suitable for outdoor use only. Provides additional protection against leaks.Easily removable if necessary.

There are specialized coatings for metal, they are divided according to their properties:

• Anti-corrosion - compounds that protect the metal from moisture and oxygen. Does not require a primer coating.
• For rust - applied directly to oxidized iron. Such paints significantly reduce the time and financial costs for metal processing. Quick drying. Produced on the basis of synthetic epoxy resins with the addition of anti-corrosion pigment.
• Hammerheads - when dried, they form potholes on the surface, similar to hammer blows. They can be produced on an alkyd, acrylic, epoxy base with the addition of small particles of glass and aluminum powder. Resistant to mechanical damage.
• Primer-enamels are formulations that combine the properties of a primer, an anti-corrosion coating and an enamel.
• Nitro paints - such compositions are most often produced in spray cans. They are toxic, so the paint in spray cans is used only for outdoor work. Its advantage is that staining does not leave streaks.
• Blacksmiths are made on the basis of polymers. One of the most durable. They have the highest adhesion rates to the base surface.

As a rule, the more expensive the composition, the longer it will last. The most affordable - oil ones - can lose their appearance and crack in just a couple of years. Nitro paints fade in the sun in one season. The hammer has the greatest durability - even after 10 years of operation, it will not change its appearance, but if necessary, it is almost impossible to remove it. The best paint for metal is blacksmith paint, but given its high cost and high consumption, it is not always advisable to use it.

When choosing, be guided by the following indicators:

• Purpose (for indoor or outdoor use);
• Toxicity;
• Consumption and cost;
• Duration of operation;
• The need for preliminary preparation of the metal.

The condition of the metal surface is also important. If it is required to paint ferrous metal with rust, the choice of compositions is narrowed

Also in the case of products that will be exposed to heat or weather conditions.

Choosing the best paint for metal

Of all the colorants previously listed, hammer effect coatings have the highest performance in terms of basic quality criteria. In terms of external characteristics, the coating has similar features to rubber dyes, since both have a similar consistency. However, these materials have completely different compositions, and a different binder component was used for their manufacture.

In order to protect forged products from the effects of atmospheric agents, it is worth choosing the right paint for metal

The significant disadvantages of hammer paint include only the high price. Its use will be profitable only if a small surface is processed, because the application of this composition is accompanied by a high consumption. If, in financial terms, there are no restrictions, then it is hammer paint that can be considered as an ideal option for finishing metal surfaces in the open air.

Important! Hammer paints must be used in combination with the same brand of primer. Provided that this requirement is maintained, the service life of the coating will be at least 20 years.

Comparative characteristics of dyes

The table clearly shows the advantages and disadvantages of various types of dyes according to the main parameters, where 1 is the lowest and 4 is the highest.

Regardless of the type of paint chosen, the surface should be pre-cleaned from the top layer of rust and dirt

Popular paints for galvanized metal

Not every type of dye is suitable for finishing galvanized metal surfaces. That is why there is a separate category of materials intended for these purposes. Moreover, such paints are produced both in the form of a powder, which needs to be diluted, and in the form of a ready-made mixture. The composition, which does not require preliminary preparation, is packaged in cans, buckets and aerosol cans.

According to consumer reviews, Cycrol paint for galvanized metal is the most demanded in this category. Customers appreciate the ease of use and high quality of the coating on any application, including brush, roller and airless.

No less in demand are the compositions of Zinccomet, which are noted by users as convenient dyes to use with optimal parameters and cost. The only drawback is the only limitation for application to coatings at low temperatures, but most users on the forums consider this nuance insignificant.

Due to its anti-corrosion properties, metal paint is able to protect the roof of a private house from negative external factors.

Basic colors are presented in a small number of shades, which, as a rule, include white, silver, black, brown and green. A separate place is reserved for anti-corrosion silver paint for metal, the price of which is more than affordable.

Possibilities of Hammerayt hammer paint for metal

Among hammer coatings, Hameright metal paints from the manufacturer Akzo Nobel are especially popular, which offers customers a lot of advantages:

• protection of metal surfaces from corrosion damage both indoors and outdoors;
• spectacular appearance is provided due to an unusual texture and a variety of colors, including standard and exclusive shades;
• a high level of adhesion even over rust and maintaining an attractive appearance for at least 8 years;
• operating temperature range in the region from -20 to + 85 ° С.

A thin coat of hammer paint can be used to create an interesting effect on metal fittings.

Under the condition of a short exposure to high temperatures, the coating will retain its attractiveness (up to + 150 ° C). For at least 5 years, the finish will not undergo any changes in shade under the influence of UV. These and many other benefits have made Hammerayt so popular in the market.

The modern range of paints and varnishes offers hundreds of quality finishes. However, there is no universal composition. When choosing a finish, first of all, you should be guided by the type of material of the surface to be treated, the budgetary possibilities and the advantages that the dye can offer.
