When carrying out repairs, it is often necessary to face the need for painting metal products. The big problem in this case is that the metal is able to oxidize when exposed to moisture on its surface. In order to eliminate rust, it is necessary to perform mechanical cleaning, after which anti-corrosion paint for metal can be applied to the base for metal, reviews of which are presented below.
Solution
These manipulations are troublesome, and sometimes designs are not available for scraping rust. In order to ensure this process, manufacturers have taken care of creating rust paints that can be used as decorative coatings. These compounds are modern, they have a wide area of use.
Reviews of anticorrosion paints
Anticorrosion paint for metal on rust has many advantages, among them consumers note:
- the possibility of applying directly to rust;
- creating a protective coating on the metal surface that repels dirt and water;
- good hiding power, high adhesion;
- anti-corrosion durability;
- quick drying;
- wealth of colors.
However, it is worth highlighting the disadvantages, among them consumers note the lack of the ability to paint objects that during operation will be heated to 150 ° C and above. Among other things, according to customers, after painting, the surface should not come in contact with drinking water or food.
Types of paints by rust
If you need anti-corrosion paint for metal, you should familiarize yourself with its main types. In order to achieve the desired effect during surface treatment, it is necessary to understand the areas of use of compounds for rust. These mixtures are classified by type of basic substance, maximum temperature, as well as the number of components. For example, water-borne paints containing phosphoric acid can be found on sale. They will have to pay the least, but the resistance of the surface to the environment will be minimal. Among other things, manufacturers offer two-component compositions, the ingredients of which are added epoxy resins, corrosion inhibitors and polyurethanes. Anticorrosion paint for metal on rust can also be:
- epoxy;
- oil;
- alkyd;
- acrylic;
- hammer.
Epoxy compounds are toxic; therefore, they cannot be used in everyday life. They are suitable for heated metal structures. The composition of oil mixtures contains natural oils and drying oil. The surface after drying will be characterized by low resistance to temperature effects. If the product is used outdoors, the anti-corrosion protection of oil paint will decrease, therefore, these compounds are recommended to be used indoors. Anti-corrosion alkyd paint for metal is intended for galvanized metal, it is flammable, therefore it should not be used for heated structures. Application will be very simple, as the mixture has a high degree of adhesion.
Overview of rust paint features
On sale you can also find acrylic paint, which is suitable for highly heated structures. It can be used for heating elements both outdoors and indoors. To restore rusted metal in a short time, you can use special paint on rust, which contains three components. The process using this mixture will be cheaper, the application of paint can be carried out in a short time and even on an untreated surface. Among the ingredients are anti-corrosive substances and resins. The paint dries quickly, and after completion of this stage it will be able to protect the metal for 8 years.
Hammer paints allow you to achieve a rough surface with a metallic sheen. Among the ingredients are alkides, epoxides, aluminum powder and acrylic. Hammer mixes can be used for non-ferrous metals, and the primer may not be used before application. The first layer acts as a primer, while the second is anti-corrosion. But the third is used as enamel. Using hammer paints, it is impossible to protect surfaces that will be heated during operation above 150 ° C.
Application features
Corrosion-resistant paint for metal, the use of which should be carried out according to the instructions, is applied to the prepared surface. The base should be cleaned, degreased and dried, freed from old layers of paint with emery or a brush for metal. The master can get rid of large irregularities by a crusher. Experts recommend pre-priming, which improves the quality of adhesion, making the layer more durable. If you use primer, then this step can be excluded.
The next step will be the application of paint, while remembering that the temperature of the environment should vary within 20 ° C, while humidity should be 80%. The paint is agitated and diluted with a solvent, while using a 9: 1 ratio. It is not recommended to apply more than three layers, the composition should not be dissolved by a nitrocellulose mixture. For work, you can use the spray gun, between the layers should wait for 15 minutes.
Characteristics of paint -0278
If you are interested in the question of what properties paint on metal has on rust grade -0278, then you should familiarize yourself with the information presented below. The opacity of the dried film is from 60 to 120 g / m 2 , the final value will depend on the color. The hardness of the film according to the pendulum device is 0.15 mm The rust conversion conversion coefficient is 0.7, and the film is resistant to the static effects of sodium chloride solution for 72 hours. These compositions are made according to specifications 2313-174-21743165-2000.
Reviews of XB-0278
According to users, long-term protection using the composition of the XB-0278 can only be achieved if the metal structure does not come into contact with electrical solutions, capacitors and oxygen. The rust area will be completely insulated after application of the paint. As another advantage that the described soil-enamel possesses, there is the absence of restrictions on the area and form of processing. Among other things, the protective coating has high decorative properties. The coating can be tinted in different colors. There is another characteristic of such material as paint for metal and rust. Her choice is justified if you need to protect a metal garage, the roof of the house, power lines or other types of buildings. This paint is easy to apply. You can carry out the work yourself. According to customers, the master must use personal protective equipment, providing intensive ventilation indoors.
Conclusion
The above paint for metal on rust is anti-corrosion, the price of which is 118 rubles. per kilogram, it is distinguished by its ability to protect building and other structural elements from the negative impact of the external environment. The above compositions are able to maintain performance in a wide temperature range: from -50 to +80 ° C. This is also true if the design will be exposed to sudden changes in temperature.
