When it comes to protecting the surface from chemicals or the effects of acidic elements, a special treatment agent is required. To him put forward special requirements.
One of the best methods of protection is to apply acid-resistant paint to the surface. It copes with all chemical loads and perfectly preserves the surface of structural elements. This paint has many protective effects, which will be discussed later.
general characteristics
A considerable assortment of paints of the presented type is presented on the market. Some of them are already known, are in good demand. One of these compounds is acid-resistant enamel XB-785. The production of this substance has been going on since the time of the USSR.
And as statistics show, this composition was painted a lot of surfaces that were operated in adverse environmental conditions. Paints, depending on the manufacturer and pricing policy, may differ from each other by elements of the composition. The preparation process for carrying out work on their application is unchanged in almost all cases. It may differ only depending on the characteristics of the base.
Paint composition
Acid-resistant paints have a number of special characteristics. The basis of the composition is a mixture of alkyd and polyvinyl chloride chlorinated resins mixed with organic solvents. To improve the quality and increase the protection of the layer from negative influences, plasticizers and pigments are added to the composition.
Ready-made liquids are recommended to be used only to create a comprehensive protective coating. In other words, if anti-acid paint is applied to an unprepared surface, then its barrier properties will be lost during operation. In this case, the manufacturer does not guarantee the long-term use of the coating.
Only by observing all technological standards can the maximum level of protection of structures be ensured. Acid formulations are intended for coloring a wide variety of materials, namely:
- metal surfaces;
- wooden products;
- military equipment;
- industrial equipment;
- plastered objects;
- concrete structures;
- other things.
The tool can be used both inside and outside the building. The application of this composition is carried out using a spray. The use of a brush, roller or fouling in this case is not recommended by the manufacturer.
Varieties
It is worth noting that the product range includes a number of colors. The palette is presented in such shades:
- white;
- yellow;
- red;
- the black;
- Gray.
The most popular is the gray type of paint. They mainly stain chemical and industrial equipment. According to GOST, different colors are allowed for enamels XB-124, 785.
After painting the elements and following all the technical recommendations on the packaging, the surface will be isolated from the adverse effects of the environment. Characteristics of the barrier function are guaranteed by the manufacturer. It is not recommended to use the product at temperatures above 60 ° C, as this will reduce the quality properties of the paint.
Varnish and two-component composition
Before painting any surface or product, it should initially be primed. For this, varnish XB-784 is used. Its characteristics, properties and quality are regulated by the norms of standard 7313-75. The use of varnish improves the strength of the base, helps to obtain good adhesive properties between the elements. Also, this procedure extends the service life for many years, provides reliable protection of the coating.
The primer for painting has two components. These are epoxy paints and hydrocarbon resins. This composition provides high-quality surface preparation before further processing. Paints of this type should be mixed well before use. This is required by the instruction. Partial mixing is not recommended. This may violate the proportion and properties of the composition. So the mixing process takes place using a drill with a mixer at low speeds.
Two-component varnish can be applied both with a spray gun and in any comfortable way, for example, with a brush, roller or mowler. Work with varnish -784 should be carried out at least with gloves. Be sure to adhere to safety regulations.
Surface preparation
Before starting work with acid-resistant paint, a base should be prepared. The surface must be dry. Then the composition will have better adhesion. It is not necessary to apply the composition to a moist base, as this will significantly reduce the quality of the work done.
Therefore, moist places should be dried with a building hair dryer or a warm gun before applying the composition. The surface before applying the paint should be cleaned of dirt and various stains, such as bitumen or petroleum products. After that, you can start repair work.
Features of the work
Before carrying out work, you should pay attention to weather conditions, whether any precipitation is planned. This is explained by the requirement that drying should take place without direct ingress of water.
Also, do not dilute the acid-resistant paint with anything. This will instantly reduce its protective qualities and lead to the need to redo the work. It is recommended to apply the composition to the prepared surface at a temperature of +5 to +30 º.
To work with enamels XB special skills are not required. This paint is very easy to use. The primer for painting should be applied in 1-2 layers. This will significantly improve paint adhesion. After preparing the surface, a first coat of paint is applied. It should dry. Therefore, a second coat of paint must be applied after 60 minutes. Complete drying of the painted object and the acquisition of all operational characteristics occurs in a day. The composition is recommended to be applied in 2-3 layers. The approximate enamel consumption for one layer is up to 150 grams per 1 m².
Security requirements
Special acid-resistant paints for metal, wood and concrete are designed to prevent the effects of salts, acids and gases on the object. Means include a number of components that can be harmful to health. Therefore, it is worth remembering safety standards.
Enamel XB-785,124 has the ability to ignite. Therefore, when working with it, it is necessary to comply with the fire safety rules. When opening cans, it is forbidden to use a chisel, a hammer, as well as any tools that can cause a spark. Apply both the lacquer composition and the paint when using personal protective equipment. For example, it can be a dressing gown, gloves and a respirator. If it enters the skin, the paint may be harmful to health, cause allergies or irritation.
Manufacturer
Almost all acid-resistant compounds are produced at enterprises in Russia and the CIS countries. All products on sale are confirmed by a factory passport, and also comply with the relevant standards. During production, products undergo quality testing at all stages of production. She receives the opinion of the OTK commission on the compliance of the standards with GOST and TU.
Recommendations of specialists
There are certain recommendations of the masters, what you need to pay attention to when acquiring an acid-resistant paint. Such materials should be bought in specialized stores. It is necessary to pay attention to the expiration date and the availability of related documentation. Also, before using the product, you should read the instructions on the package.
Having considered the features of acid-resistant compositions to protect various surfaces, you can correctly select the appropriate type of paint and apply it correctly on the surface.
