Helpful advice on how to use the rust converter correctly

foto21426-1Metal corrosion is common in the absence of a good coating. The appearance of rust is facilitated by the access of oxygen and being in a humid environment.

To prevent the spread of rust, and to eliminate it qualitatively, special preparations are used - rust converters.

We will tell you about how to use rust converters correctly in the article.

What do you need to know before using?

Corrosion products converters are agents that, as a result of a chemical reaction, stop the spread of rust and form a reliable polymer film on the metal.

They are produced in the form:

  • paste,
  • liquids,
  • gels.
The coating created by the transducers serves as an intermediate layer between the metal and the final paint coat. Without the use of a converter, the metal remains unprotected and can corrode even under a layer of paint.

Studying the instructions for the selected rust converter is a prerequisite for the success of the work.

In order for anti-rust agents to work as efficiently as possible, the metal must be prepared for processing. It needs not only to be cleaned of dirt, but also to remove loose fragments.

foto21426-2Depending on the size of the damaged area and the type of item that needs restoration, can be used to influence:

  • metal brushes;
  • scrapers;
  • grinding machines;
  • sandpaper, etc.

After cleaning the metal mechanically, the surface is prepared for processing by the converter. If the cleaning is done inaccurately, even after using the chemical, areas with active rust may remain.

Negligence in stripping can result in the return of corrosion.

Application methods

Most anti-corrosion agents are ready-to-use... Depending on the consistency and form of release, they can be equipped with a brush for easy application, a spray, etc.

The final result of processing depends not only on the chosen tool, but also on compliance with all the rules for its use.

General instructions for use converters:

  1. Training. Surface cleaning.
  2. Solvent degreasing of the metal area that needs to be removed from the rust.
  3. foto21426-3Shaking the bottle (if specified in the instructions).
  4. Application of the converter (in strict accordance with the instructions for a particular product).
  5. Rinse if necessary.
  6. Solvent degreasing.
  7. For converters that do not form soil, a primer is required.
  8. Application of the final paintwork.

Many preparations, simultaneously with the transformation of corrosive areas, create a soil and do not require subsequent washing and priming. For other cleaning agents, it is a mandatory stage of work, since the substances remaining on the metal can themselves become a source of corrosive processes.

If the converter has not coped with the task of removing rust the first time, the treatment must be repeated. The number of repetitions is not limited.

Prohibitions and nuances

The use of converters should take into account the peculiarities of the composition of the tool and the components included in it. All drugs are divided into two main groups:

  • acidic;
  • acid-free.
The former cannot be applied to a damp surface, which imposes application restrictions. In this case, not only degreasing is required, but also high-quality drying of the metal.

Some converters are capable of reacting with paints and varnishes that cover adjacent areas with the corrosion zone. Such preparations require very correct application.

If you are not sure about the accuracy of the work, it is better to give preference to compositions that are neutral to paintwork... The main prohibition is not to use the transducer on unprepared metal.

Precautions

Rust converters are used in bodywork and, if necessary, restore other metal objects damaged by rust. All products offered by manufacturers are drugs with high chemical activity.

foto21426-4Their use should be carried out with the obligatory observance of precautionary measures:

  • high-quality ventilation at the work site;
  • availability of protective equipment (gloves, goggles, respirator, etc.);
  • use of the product only for its intended purpose;
  • storage in a place protected from children;
  • application before the expiration date.

Advice

In order for the use of converters to be as successful as possible, the following expert advice should be considered:

  1. Work with chemicals must be carried out in personal protective equipment and with good ventilation.
  2. It is advisable to degrease the metal with solvents, since degreasers and thinners may not give a good enough result.
  3. When purchasing a converter, you must first calculate what size the area will have to be processed.
  4. If the treatment area is large, and the work must be carried out in a short time, it is convenient to use the products in packages with a spray.
  5. Acidic preparations are well suited, for example, for treating the car body. But for the protection of rolled metal, fittings, pipes - a product based on an organic compound - tannin - may be the best choice.
  6. Liquid converters are more convenient for small areas of corrosion, as well as for machining small parts by immersion.
  7. To work with inclined metal surfaces, it is advisable to give preference to preparations that have a thick consistency - they will be better distributed and will not drain.
  8. It is recommended to treat hard-to-reach areas from an aerosol can - this will significantly save time.
  9. The application of any of the products should be of high quality, completely covering the damaged area of ​​the metal.
