How to remove rust from metal at home

To make the house look attractive and constantly create a festive atmosphere, everything absolutely must be beautiful in it. Particular care is required to ensure decorative and high-quality protection of metal structural elements. Modern paint and varnish materials for metals will help in this. So, if you are wondering how to remove rust from metal, then everything will be concerned with this particular issue.

What are we dealing with?

In everyday life and modern construction, a huge number of steel structures are used, which must be carefully protected from the negative environmental factors that lead to corrosion - the destruction of metal under the influence of electrochemical and chemical processes. Over time, corrosion leads to a decrease in the strength of metal products and their destruction, gradually they lose their appearance and lose their structural qualities. Corrosion processes occur at different rates, depending on the conditions in which the product is manufactured and used. Since it is almost impossible to completely eliminate atmospheric effects on metal structures, therefore, the protection problem is in the foreground. Or the question arises: how to remove rust from metal?

The simplest way out

In practice, it has already been repeatedly proven that any metal construction is easiest to protect by applying special paints. In comparison with other types of protective coatings, there are a number of advantages in paint and varnish: ease and high speed of application, the possibility of obtaining a coating of the desired color. Quite an important point concerns the possibility of processing metal structures of complex configuration and large dimensions. Thanks to the use of modern paint and varnish materials and tools, it is possible to maintain metal products in good condition without much effort. With the right care, you can count on years of service.

However, in any case, before painting, you need to get rid of the effects of corrosion processes, which could well have started. That's why the question arises, how to remove rust from metal?

Substrate preparation

From the surface of the metal it is required to remove the old coating, so that the adhesion of the paint is more qualitative. The next step is to clean the surface of various contaminants, as well as from rust, which could already appear there. The cleaning method can be chemical, thermal or mechanical. If you continue to talk about how to remove rust from metal at home, it is worth considering each of them.

The first method involves the use of alkaline detergent compositions or active solvents to remove a variety of organic compounds. This is what will help you in deciding how to remove rust from metal chemically. A mechanical method is understood as the attraction of abrasive materials, it can be shot, sand, a mixture of water and sand, sandpaper and others, or special tools - grinders, brushes, knives, etc. By this method, a cleaned surface with a uniform roughness is obtained, which promotes an increase in the degree of adhesion to the paint film.

The thermal method involves the use of a thermofan or a flame of an acetylene burner.

Treatment

So, when it became clear to you how to remove rust from the metal, it's time to talk about further surface treatment. After cleaning, the following preparatory procedures should be carried out - priming and puttying. The first operation is carried out to create a sufficiently strong connection between the painted surface and the remaining layers of paintwork materials. Priming also provides a high degree of metal resistance to corrosion, blocks pores and other defects. So, if you already understand how to remove rust from the metal before painting, then it should be said that the priming is the following procedure after the surface cleaning work is completed. It consists in applying to the surface a thin layer of a special composition called a primer.

Types of compounds

So, if you are interested in how to remove rust from the metal of the car, the primers, which are rust converters, are quite convenient in practical terms. This is due to the impossibility of completely removing traces of corrosion from items of complex or intricate shape. Use this composition is quite possible after the mechanical removal of the top layer of rust, which looks very friable. In the composition of such primers there are special modifiers that transfer iron oxide to a new state - tight adhesion to the surface of the metal. Such compounds do not interfere with the corrosion resistance of the coating and its adhesion. Often the modifiers are derivatives of phosphoric acid, as well as a number of tannins.

Next stage

After completion of priming, the time of the next operation - shpatlevaniya - comes. This method is designed for sealing gaps, leveling the surface, giving it uniformity. Putty is a mixture consisting of a plasticizer, a filler, a binder and special additives.

Mixture for shpatlevaniya can be sold in dry or ready for use form. Usually, the putty is applied to the surface by means of a spatula and its further leveling. And when the base is completely cleaned, primed and zashpatlevano, you can start painting the paint, which is the finish.

The paint on metal surfaces can be applied by means of brushes, sprayers or rollers. The number of coating layers depends on its hiding power. So, now you not only know how to remove rust from metal, but also how to protect it so that in the future such problems do not arise.
