To get the best results, proper application and preparation are essential. You can make sure your external metal surfaces are protected and continue to look great for many years to come by being aware of the various types of metal paint and their characteristics.

Basic species

There are the following varieties of enamels for metal surfaces:

  1. Acrylic. Can be used for internal and external decoration. The compositions provide reliable protection with metal bases for 7-8 years. Coating is resistant to negative factors, ultraviolet and oxidative processes.
  2. Oil. The mixtures are usually used indoors, since they are negatively affected by temperature changes and it is not always advisable to use them for external decoration. In addition, the compositions do not protect against humidity, and the design quickly rust.
  3. Alkyd. Well suited for processing galvanized products. But the main disadvantage is instability to high temperatures, and increased combustibility is also characteristic. Mixtures can be used for processing galvanized metal both inside and outside. Differ in resistance to corrosion.
  4. Epoxy. Due to the high toxicity of the mixture, it is rarely used in private construction. But in industry they are used thanks to reliable protection of products from high temperatures.
  • Rapid -drying paint for metal;
  • Powder paint for metal;
  • Soil enamel for metal;
  • Paint in spray can of metal;
  • Hammer paint for metal;
  • Heat -resistant paint for metal;
  • Epoxy for metal;

The use of paint on rust

Metal surfaces need to be well-protected against corrosion. Paints, soils, and soil-enamel mixtures are suggested for this. The characteristics of the material, color, drying time, and processing technology are also differentiated based on the product.

Actions in preparation are needed. Rust, pollution, and other things are taken off the surface. P. Degreasing the base is frequently necessary. Two layers of the mixture are applied to achieve a rich color.

Based on the primary aspects of paint application, they differentiate:

  • color spectrum;
  • long service life;
  • application to rust;
  • quick drying;
  • atmospheric mixture;
  • resistance to negative environmental influences;
  • good covering and reliable adhesion to the base.

However, surfaces of equipment that operate at temperatures higher than 150 °C cannot be processed using paints. Applying mixtures to surfaces that serve as drinking water containers is prohibited because they may be harmful to the body.

Soil is an enamel in rust

When applied to a rusty base free of soil, the mixtures can be used to process various metal bases. Composition: anti-corrosion enamel mixed with primer. This makes work easier.

  1. Clean the base from dust, pollution, fat traces.
  2. Remove the upper layer of rust, Using sandpaper or metal brush.
  3. Process the base any solvent.
  4. Mix the composition thoroughly and apply to the surface in 2 layers. At the same time, the minimum interval between them is 30-40 minutes, although for a better result you need 3-5 hours. But you can not overexpose, because then you will have to postpone the work for a month until the coating gains complete strength. Otherwise, with non -compliance with the recommendations relating to the time between the application of the layers, the processing will be ineffective.

To ensure you have time to complete your work during the day, it is advisable to read the manufacturer’s instructions beforehand.

Anti -corrosion coloring compounds

The compositions lengthen the life of the base by preventing rust and improving the material’s qualities. Paints are one-component, fast-drying mixtures. In addition to offering anti-corrosion protection, the composition gives the coating decorative qualities.

By applying the mixture, you can obtain a surface that is half-material and glossy but matte, resistant to pollution—one of the main factors contributing to rust.

Paints are utilized in both commercial and residential building. Particularly appropriate for handling gas and tap connections, roofs. They can be applied practically anywhere that corrosion protection is needed. Additionally, the mixture has a higher resistance to moisture because silicone components are present in its composition.

Paints can be used in nearly every climate because they can be applied to metal products’ surfaces without the need for primer at -20 to +70 degrees Celsius.

Choice recommendations

It is advisable to consider certain factors when selecting anti-corrosion compounds and products for painting and safeguarding metal bases, as paint intended for external surfaces may not be appropriate for internal use. Furthermore, there are differences in the technologies available for painting the grounds.

The primary things that need to be considered are:

  1. The details of the furnaces are treated with mixtures that can maintain their properties at temperatures up to +450 … +500 ° C.
  2. When staining heating equipment, heat -resistant types of colors are recommended. In this case, the characteristics should allow the compositions to withstand 150 ° C.
  3. Colormetals are treated with specially designed primers.

Numerous factors need to be considered when making a decision, ranging from the operating temperature to the final color of the treated surface. Thus, before making a purchase, it is best to speak with an expert or thoroughly inspect the goods.
