Certificate of conformity for the floor AK-070

The primer mixture has a sanitary-epidemiological conclusion of the Central State Sanitary-Epidemiological Service, valid throughout Russia. The composition can be used in the shipbuilding and civil aviation industry.

During the production of the primer, all provisions of GOST 25718-83 are taken into account. The material contains several ingredients that increase the degree of adhesion, covering power and resistance to aggressive factors. These include in particular the following:

• pigments - due to their content, the primer acquires a yellowish tint after drying;
• acrylic resins - used to increase the level of adhesion to the base;
• polymers and plasticizers - have a positive effect on adhesion.

It should be mentioned separately that in the AK-070 primer mixture, a combination of inorganic varnishes is additionally used. However, this information is not on the packaging and in the instructions. A tip is the recommendation to use 648 Series Thinner for thinning.

After application, the substance quickly hardens. In this case, a smooth, homogeneous film is formed, which does not contain additional components and granules.

The non-volatile components represent 13.5 to 16% of the total. The drying time should not exceed half an hour. If after the specified time the composition has not changed its structure, this indicates a marriage or a fake.

At the same time, the material also has some drawbacks. The main drawback is the presence of toxic components in the composition. Therefore, when using the substance, it is imperative to use protective equipment.

Varieties of composition and color

Primer AK-070 is produced in one modification. After drying, a uniform yellow film appears on the surface of the coating.

Separately, it is worth mentioning the composition of the primer, which is marked as AK-070 M. It is a more viscous material, in which up to 39% of non-volatile substances are present.

Soil technology

In order to obtain a reliable primer layer, it is recommended to strictly follow the instructions for applying the material.

Material consumption calculator

Under normal conditions, material costs are 115 to 153 grams per square meter. In this case, the exact consumption depends on the method of application of the substance and the characteristics of the preparation of the metal surface.

Tools required

You can use a gun or a brush to apply the coating. In addition, it is worth preparing degreasing agents and napkins. To clean the surface of the old coating, you will need sandpaper or a special drilling attachment.

Surface preparation

It is much easier to apply a primer to a new product than to an old one. This is due to the need for careful preparatory work. To achieve good results, it is necessary to thoroughly clean the coating from rust and old paint residues.

It is recommended to use a metal spatula for cleaning procedures. However, for large surfaces, it is better to use sandblasting and shot-blasting. You can use sandpaper or mesh to remove the old coating yourself. A drill is also suitable for this purpose.

After completion of the work, dust, dirt, dye residues, moisture, scale, grease should not remain on the surface of the material. After cleaning the surface, no more than 6 hours should elapse before applying the primer.

Application methods

The product mixes easily. It is immediately ready for use.You can use a solvent to dilute the composition. However, such a substance should be used only with an increased viscosity of the solution.

It is recommended to apply the primer no later than 6 hours after cleaning the base. It is very important to ensure that no dust accumulates on the surface. It is allowed to apply the composition with a brush or a spray bottle. It is allowed to do it in 1 layer. However, experts advise doing 2 layers.

Drying time

Drying one layer at a temperature of +20 degrees will take about 30 minutes. Lower settings will take longer for the primer to dry. The service life of a single-layer coating is 2 to 5 years. The specific period depends on the conditions of use and the climate.

Precautions and safety measures

The primer is considered flammable. Therefore, it is not recommended to use it near open fire sources. It is recommended that all work be carried out in good ventilation conditions. In this case, it is necessary to use personal protective equipment.

When applying the composition, it is important to avoid its penetration into the respiratory and digestive organs. If the substance gets on the skin, wash it off with warm water and soap.

Application errors

The main difficulty in applying a primer is considered poor surface preparation. If the metal is improperly cleaned, there is a high risk of the coating peeling off. As a result, the dye will lose its adhesion to the surface, which will lead to a violation of its structure.

Rapid corrosion is considered to be another common problem when applying the composition to metal substrates.This is the case if rust is already present under the primer. In this case, it will be necessary to re-fight against corrosion and apply a primer.

In addition, the paint can peel off if the coating is improperly treated with degreasing agents. If any grease remains on the surface, it will interfere with the even application of the dye. It is necessary to rinse it well and wipe the surface with a towel soaked in white spirit. Then the solution should be washed off with warm water, and the surface should be thoroughly dried.

If the surface is very wet before using the primer, the next coat will be of poor quality. In this case, it will quickly peel off.

If you have to apply several layers at once, it is important to respect a certain time interval. It is indicated on the packaging. Thanks to this, the previous layer will have time to seize, and the next will lie evenly. If this recommendation is violated, the coating will have an uneven thickness.

Cost and storage conditions

It is recommended to store the product in a dry, dark place at a temperature not higher than +30 degrees. The shelf life is six months. Packaging a primer will cost about 200 rubles.
