Fireproof coating is a special material that is designed to protect any structure from the destructive effects of fire. Most often it is used in construction and industry (heavy, aviation, ship). However, you should understand what types of protective materials are, how they work, and also how they should be used.
The advantages of the presented coatings
First of all, find out what advantages they have. Fire retardant coating has such advantages:
1. Affordable cost.
2. Effective protection of the surfaces of structures from the negative effects of high temperature.
3. The possibility of using materials for metal or wooden products.
4. The choice of protection by type of application.
5. Additional functions of the compositions, for example, the ability to protect the structure from rotting or damage by insects, cracking, the ability to change the color of the treated surface, which allows it to be additionally decorated.
Tread principle
So, fire retardant coating is very important for maintaining the integrity of the structure during a fire. Naturally, it should be used when the product is already ready for final decoration. During a fire, the composition is able to prevent the structure from igniting for a long time. The fact is that it contains special substances - flame retardants - which are not amenable to burning.
While heating the protected surface, they begin to act. In this way, the building owner can provide a reliable barrier to the spread of fire throughout the structure and gain the time required for the arrival of the fire brigade.
Varieties of tread materials
Fire retardant coating may be different. There are such types of materials:
1. Impregnation or varnishes. They can be applied using a regular brush or roller. In addition, a spray gun is also used for this purpose. Most often they have a liquid consistency. Their feature is that they are used to protect the tree and can perform other functions. So, impregnations help maintain the integrity and structure of the structure. Varnishes provide a change in their decorative properties. In addition, the product protects the surface from rapid fire.
2. Coatings. Their feature is that during the interaction with high temperature, they are able to form a thick protective shield of non-combustible foam. Under normal conditions, such a coating is almost imperceptible and reflects heat well.
Where exactly are the substances presented?
Naturally, it is not possible to use such coatings everywhere, although the spectrum of their application is very wide. For example, wood is most often treated with such varnishes or impregnations. You have already read about the advantages of such a finish above. In addition, such processing is necessary in the process of laying communication cables (electrical). In addition to the fact that they must be isolated, they should be painted over with a special flame retardant.
Naturally, a fire-retardant coating of metal structures is produced, which are used in the construction of residential buildings or industrial buildings, and also lend themselves to periodic heating. For example, materials such as those used in the construction of aircraft engines and various mechanisms should be processed.
Interestingly, even home furniture, curtains, carpets, daily household items can be soaked with flame retardant. Naturally, this should take into account how safe the selected composition is.
Features of the protection of wooden structures
So, wood processing is one of the stages in the construction of any building. Otherwise, the materials may crack, be damaged by insects, or catch fire quickly. To prevent such troubles, various flame retardants or coatings exist. Moreover, they can be both colorless and have a shade. Decorative varnish with flame retardant properties can be used for processing solid wood, plywood, and chipboard. Moreover, the tool is used both indoors and outdoors.
For processing wood structures, not only flame retardants can be used, but also ordinary paints in which they are contained. In order to more reliably protect the structure from dangerous heat, it is advisable to use deep impregnations that penetrate into the product.
The surface of the structure can be treated with a brush or spray gun. The second method is considered more economical as well as effective. Apply varnish in dry weather, so that it dries faster. Note that you will have to paint over the surface several times. However, each subsequent coat should be applied at least 3-4 hours after the previous treatment.
Fire-retardant coating of wooden structures is not only cost saving, because products can last much longer, but also the confidence that you will save your property in time, and maybe life in case of fire.
Features of the processing of metal products
It is difficult to attribute metal structures to flammable ones, however, under the influence of high temperature they are able to melt, deform, and even burn out. Naturally, in this case, the integrity of the entire building is threatened. Therefore, to protect structures made of metal or concrete, flame retardants must be used. They will ensure the impossibility of moving open fire from one room to another and significantly reduce the risk of building destruction.
Most often, in such cases, water-based paint is used, which, when exposed to high temperature, foams and forms a durable non-combustible layer of foam. It should be used both inside the building and outside. It should be noted that such a tool is not toxic and is mandatory for use in those buildings that are at high risk of fire. In addition, such liquids have good adhesion.
It is very important to use a fire retardant coating for ductwork. It is through this design that a fire can spread rapidly. In this case, it is better to use an inorganic thermal insulation coating that does not change the appearance or properties of the ducts.
That's all. Be careful!
