Features and types of acid-resistant paints, colors and rules of application

Acid-resistant paints are effective materials that provide surface protection against external aggressive factors. These products are not destroyed by acids or other chemical elements. These dyes are used to treat surfaces that need to retain their properties for a long time. There are many products on the market that differ in their composition and colors.

Characteristics of anti-acid paints and varnishes

Acid-resistant paints have the following characteristics:

• The material is based on a mixture of two types of resins. These include alkyd and polyvinyl chloride. These substances are mixed with organic solvents. Additional components can be pigments. In addition, dyes contain plasticizers that improve the properties of the material and increase the resistance of protective coatings to external factors.
• The ready-to-use composition can be used exclusively as part of a combined protective coating. In other words, applying paint to surfaces that have not been prepared for it can lead to unpredictable results.
• Acid resistant compounds can be used for application on various materials.These include concrete, metal, plaster coatings. Paints and varnishes are suitable for painting the interior of buildings and facades.
• After the material dries, the surface acquires the properties declared by the manufacturer. But at a temperature of +60 degrees, substances lose their properties.
• The application of acid-resistant substances is only permitted by spraying. Brushes and rollers should not be used to work with such products.

Appointment

Ready-made liquids resistant to chemicals can be used to create a complex coating.

In other words, applying an acid-resistant colorant to an unprepared coating will result in a loss of its barrier properties. In such a situation, the manufacturer will not be able to give a guarantee of long-term operation.

Only if all technological standards are met, it will be possible to achieve maximum protection of the structure. Acid compositions can be applied to different types of surfaces:

• metal;
• TREE;
• concrete;

The formulations can be used inside and outside of buildings. The application of the substance is carried out by means of a spray gun. The manufacturer does not recommend the use of a roller, brush or brush.

Varieties and features of compositions

Today there are many effective products on sale that can be used to paint different types of surfaces.

Primer

For XB-785 substances, XB-784 varnish is used as a primer.The properties of the material and its quality characteristics are determined by the provisions of GOST 7313-75.

The use of special primer varnishes makes it possible to strengthen the substrate and increase its adhesive properties. Using a primer increases the reliability of the protective coating and allows you to increase its service life.

Two-component formulations

Recently, two-component substances that combine hydrocarbon resins and epoxy dyes are becoming more popular.

These materials are characterized by the following properties:

• Components are sold separately. Therefore, they must be mixed before application. In this case, it is important to achieve complete homogeneity of the substance. Otherwise, the properties of the coating will be worse than declared by the manufacturer. It is recommended to use a drill to mix the ingredients with a mixer installed on it. This should be done at minimum speed. This will prevent the liquid from splashing out.
• For the application of two-component substances, it is permissible to use more than one spray gun. A brush or roller is also suitable for this purpose. The choice of a specific option is due to the defined tasks and the surface you want to paint.
• When working with the substance, protective equipment is required. To do this, you need to use gloves, a respirator, a dressing gown. If neglected, the paint will cause allergies or irritation.
• After a day, the surface dries up. At this stage, it can be used even in unfavorable conditions.

Surfaces painted with acid-resistant dyes can be cleaned with detergents. This will not damage the base or change its properties.

Color pallet

Acid resistant paints are available in a wide range of colors. It may include the following shades:

• White;
• black;
• YELLOW;
• Red;
• gray;
• Green.

The most common are gray paints. They are often used for applications on chemical and industrial equipment.

General work rules

For the use of these funds to be successful, it is important to respect a number of recommendations:

• Do not mix acid resistant paints with foreign ingredients. This will negatively affect the quality characteristics of the coating.
• If rain is expected, it is better to postpone staining. The instructions for these substances indicate that the surface must dry without direct contact with water.
• Only dry surfaces can be painted.
• Before carrying out any work, the coating must be cleaned. It will not work evenly on a dirty substrate. Therefore, it is worth removing debris, oil stains and dust from it.
• It is not recommended to apply such dyes on loose surfaces. In such a situation, it is necessary to abandon staining or take appropriate measures to create a more dense base.
• It is permissible to paint the surface only under a certain temperature regime. It is allowed to do this at + 5-30 degrees.

For the successful application of acid dye, it is important to strictly adhere to the sequence of work:

• First of all, it is recommended to remove dirt from the surface.
• The wet base must be dried. If necessary, it is permissible to use a construction site hair dryer or a heat gun.
• Apply the primer to a dry, clean surface.
• Staining is best done in 2 layers. This is considered a minimum requirement as sometimes 3-4 coats of paint are required.

Special acid-resistant substances contain a number of aggressive chemical components designed to protect surfaces from gases, salts and acids. Such ingredients can be harmful to health. Therefore, when working with these substances, it is important to observe safety rules.

Some types of enamels are flammable. Therefore, when working, it is important to comply with fire safety requirements. Do not use chisels, hammers and other objects near drums which could cause a spark to appear.

It is important to use personal protective equipment when applying paints. If the substance comes into contact with the skin, it may cause allergic reactions or irritation.

Acid-resistant dyes have excellent performance characteristics and protect surfaces from the influence of negative factors. In order for these funds to give the desired result, it is important to follow the instructions for their use.
