Certa heat-resistant enamel: the nuances of use
When repairing and finishing works, ordinary paints are most often used. Heat-resistant enamels are mainly used for painting metal products. They have a protective function, protect the surface from exposure to high temperatures and adverse environmental conditions.
Key Features
The heat-resistant anticorrosive Certa enamel is made in Russia by the Spektr company. For the convenience of consumers, it is packaged in cans weighing from 0.5 to 20 kilograms. Some types are commercially available in aerosol form only. The temperature range at which the composition can be operated is from -60 to +900 degrees.
The color variety of enamel gives 26 options. Black paint is considered the strongest.
Certa enamel differs from usual paints in heat resistance.
It can be used when painting metal products, on heating mains and gas pipelines, while working with furnaces with other bases.
All products have the necessary certificates confirming its technical characteristics.
The composition of heat-resistant enamel is more complex than conventional paints. It includes more components.
When coating metal products need additional insulation. One of the properties is resistance to the accumulation of static electricity. In addition, if a current flows on the surface treated with this enamel, the mixture is able to protect it from exposure.
The composition has anti-corrosion effect and prevents the appearance and spread of rust. It withstands the effects of chemicals and severe temperature fluctuations, while maintaining its properties. It should be noted plasticity of the material, which prevents cracking of the paint when heated metal surfaces. It also gives the subject durability. The paint is suitable for indoor use..
Among the specific properties of this enamel can be noted the presence of a toxic solvent, the mandatory preparation of the base and drying under the influence of high temperatures. It takes 2-3 coats to achieve full effect.. Drying of heat-resistant enamel at a temperature of 20-25 degrees will take at least 2 days.
The paint has undergone numerous checks, after which the shelf life of the coating was set to 25 years.
Kinds
All heat-resistant enamels can be divided according to the methods of packaging, application and shelf life. Certa's different packaging volume allows consumers to choose according to the required surface area. Aerosols are packaged in cans up to 0.5 liters, which is not very convenient for using them over a large area. Per 1 square meter requires about 250 grams of heat-resistant enamel.
Information about the shelf life of the product is indicated on the label, it is usually 18 months.

Application Methods
The enamel of this brand protects the treated surfaces from moisture and corrosion, has refractory properties. Thereby it is often used in the processing of pipes and furnaces, automotive parts, in heating systems, as well as in baths and saunas.
The paint is quite easy to apply, it can be used to treat both metal surfaces, and concrete and cement bases. After drying, an even, uniform coating is formed.
Principle of operation
Before work should be trained. The jar with enamel needs to be opened and thoroughly mixed, waiting for the sediment to disappear. After that, the paint should be left for a few minutes to disappear bubbles, which can create discomfort in the work.
For dilution of the mixture using special solvents, but their composition should not exceed 30 percent.
When the work is finished, the jar needs to be tightly closed.
Enamel is applied with a roller or brush. The layer must be thin for better adhesion to the surface. When using an aerosol or spray gun, the coating is more uniform, however It is not recommended to use this method of application for working with large objects.. When applying aerosol toxic emissions into the air more than with manual, so it is better to handle small items. Experts advise to carry out all work on the street, and at the same time use a protective mask.
The number of layers depends on the type of surface being treated. For painting braziers one is enough, when working with a chimney you need 2, and brick and plaster bases are recommended to be processed 2-3 times.
Safety
Certa heat-resistant enamel incorporates solvents with pronounced aromatic properties. If the basic conditions are not followed, the materials may become unsafe for the consumer.
First of all, you need to ensure that work is done in the fresh air. If this is not possible, care must be taken to ensure that the room in which the dyeing takes place is properly ventilated and ventilated.
