If you are faced with the task of protecting the surface from rust, then you can use primer-enamel. It is used for cast iron and steel products, as well as bases that are covered with rust. Such mixtures can be applied even on the remnants of the old decorative coating, which is sufficiently tightly adhered to the metal and cannot be removed during preparatory work before applying the composition. This applies to large-sized metal structures that have a complex profile, as well as products with the most various shapes and sizes. If their cleaning is quite difficult (for example, it can be garages, grates or fences), then you need primer-enamels of the above purpose. They will allow you to effectively cope with the tasks, extending the life of the surface.
Specifications
The aforementioned compositions are used when it is necessary to repair the painting of car parts, namely the bottoms, wings and so on. If the mixture is applied in 3 layers, then it can even be used as an independent coating for metal surfaces that will be used under the influence of atmospheric influences. Such processing is also suitable for products used during operation in an industrial atmosphere, which contains aggressive gases and vapors, which especially negatively affect surfaces made of metal and cast iron. After application of the primer-enamel, salts and other chemical reagents can act on the surface, while the temperature of use can reach +60 degrees, the base, which was correctly treated with the described primer, will retain its quality characteristics and attractive appearance.
If necessary, then on top of the protection, varnishes of the type XC, NTs, EP can be applied. However, it is first necessary to withstand the base for 24 hours, drying it under natural conditions. It is important to check how well the enamel adheres to the surface and whether it is ready for further work.
Positive features
Primer-enamels have many positive characteristics, among them it can be distinguished that the compositions perform three functions at once, namely: priming, rust conversion and decoration of the coating. When using the mixture there will be no need to apply protective materials. Work can be carried out at an ambient temperature of -10 degrees. If necessary, soil-enamels can be transported and stored at low temperatures. After application, the surface dries quickly enough. All this makes consumers incline their choice towards this product, which has occupied a worthy position in the market.
Description of primer-enamel
The soil-enamel, reviews of which you can read in this article, is a synthetic resin, and during the production process, target additives, organic solvents, pigments, anti-corrosion additives and fillers are added to the main ingredients. After manufacture, the manufacturer recommends storing the composition for 18 months, which is why before purchasing it is necessary to pay special attention to the date of manufacture. If it is necessary to store or transport it is necessary to keep the container tightly closed, keeping it away from heating appliances. It is important to protect it from direct sunlight and moisture. Of course, metal enamel should be kept away from children. Among the positive features, it can be distinguished that transportation can be carried out at low temperatures.
Consumer Reviews
Rust enamel, reviews of which are presented below, can simplify the process of painting the surface of impressive areas. Consumers argue that these mixtures are easy to use for processing hard to reach places, this is due to the fact that previously there is no need to clean the base from rust. The manufacturer claims that in the conditions of the plant, targeted additives made in Germany are used, which can convert corrosion products into compounds that are difficult to dissolve and prevent the further development of corrosion on the surface. Consumers, in turn, emphasize that the soil-enamel, the characteristics of which are presented in the article, provides long-term protection of metal products and surfaces. It is worth paying attention also to the fact that the composition has high adhesive properties, this suggests that the mixture adheres firmly to a rusty surface. You can expect a short drying step. Thus, each layer dries from 30 minutes to an hour, depending on the temperature of the environment. In the first case, there is a need to maintain the temperature within 20 degrees. Home craftsmen choose rust-based primer-enamel even in cases where there is a need to process the fogging surfaces. After this, a coating is formed that is resistant to oils, atmospheric agents, salt and aggressive gases.
Before purchasing a product, you need to familiarize yourself with the expense, which is quite small. Thus, 1 kilogram of composition will be needed per 7 square meters. If there is a desire to increase the drying period, then you should maintain optimal temperature and humidity, as for the last parameter, then it should not be higher than 70%.
Recommendations for use
If you decide to use soil-enamel on rust, then the surface must be cleaned of the old coating, but this should only be done if it does not hold firmly enough. This also applies to loose scale, as well as rust. It is important to degrease the base with solvent 647 or white spirit. Before use, the soil-enamel must be mixed. Application should be done with a roller, brush or spray gun. If the composition has the wrong consistency, then it can be diluted with solvent 647.
Precautionary measures
If there is a need for internal work, then conditions should be provided that are characterized by good ventilation. After completing the manipulations, it is necessary to ventilate the room during the day. Rubber gloves should be used to protect hands . The container must be disposed of as household waste.
Conclusion
It is important not only to choose the right composition for surface protection, but also to observe the technology of its application. Thus, the primer-enamel must be applied at a temperature ranging from -10 to +35 degrees.
