Fire retardant for wood: processing

Recently, there was a fashion for natural materials, bringing people back to the roots and allowing them to live in harmony with the inner worldview. The favorite material for the construction of residential low-rise buildings, their decoration, as well as furniture is natural wood. This material, along with a large number of positive qualities, there is a serious drawback. Wooden structures are easily flammable, and fire spreads rapidly throughout the house. How to protect your home from an unexpected tragedy? This will help the latest technological developments, such as fire retardant for wood.

An interesting feature of wood

Before you start talking about a special impregnation, it is not superfluous to learn about one curious feature of wooden buildings. Yes, the tree can ignite with lightning speed and is in its structure rapidly combustible material. What, besides environmental friendliness, explains the popularity of buildings from it, despite the increased fire danger? It turns out that with rapid charring, the inertness of wood burning also increases. If the log house of the house is supplied from logs of large cross-section, the design has an increased fire resistance limit and can for a long time maintain the load-carrying capacity in case of fire. That's why people willingly build wooden houses, for insurance, additionally applying a coating of fire retardant composition.

Impregnating functions

Despite the minimal loss of working cross-section in case of fire and the durability of wooden structures in comparison with reinforced concrete or metal objects, safety standards do not particularly welcome wood as the main building material of the future building. According to the requirements of fire protection norms, the owners of each wooden structure should strive to reduce the estimated flammability. Fire retardant composition for wood, applied to the surface of the structure, well delays the combustion.

How to choose the perfect composition? Warnings

Impregnation, which increases the hygroscopicity of the material to be coated, may impair its mechanical properties. Therefore, it is difficult for an uninformed person to choose the ideal composition for his structure. There are many factors, conditions and features of a particular type of wood, each of which must be taken into account. So, if the moisture does not affect the structure in excess of the norm, then a water-based washout is suitable for treatment, on top of which a layer of varnish is applied.

Impregnation should take into account the acid-alkaline balance of space. The increased acidity of the fire retardant composition, practically equating it to concentrated acids, can harm the health of the family living in the house. There have been cases when such a fire-retardant composition for wood destroyed copper or galvanized roofing. Choosing the best composition, it is necessary to remember about its possible corrosive aggressiveness and carefully study the indicators presented on the label.

Preservation of the appearance of the structure

Each consumer wishes that the impregnation applied to the surface of the walls does not affect the appearance and does not damage their texture. In this regard, many pay attention to paint and varnish materials, which have the same properties as fire retardant. If we talk about deeper protection, then it is produced only by professionals who have the necessary license.

Efficiency

To ensure 1 group of fire safety, it is necessary to produce deep impregnation under pressure. In the residential sector such technology looks very problematic. However, specialists do not stop and are developing new and new ways of deeper application. With the help of the "Plasas" design, the fire-retardant composition is able to provide the required impregnation depth.

Active and passive means

On the market there is a large selection of compositions for professional application, performing several different functions. Active means of protection can from the inside influence the process of ignition itself, playing the role of a kind of fire extinguisher. Passive compounds are often used in the form of prevention of inflammation, and in case of fire only reduce the intensity of the fire. Even at the stage of erection of the building, some designers provide for the laying of layers of structural protection. This kind of fire-retardant composition during the installation of the building is covered with thermal insulation, the surface is plastered, additional screens reflecting the heat are additionally installed.

Kinds of used formulations

In the conditions of fire safety in wooden structures, in addition to popular impregnations, use sprinkling, paints, varnishes and fabrics. The material chosen as a protection must have a SES certificate. Sometimes impregnation with a fire retardant composition requires preliminary preparation before application. To determine the correctness of the choice of a particular tool, the professional conducts a test for the smoldering and burning of the cut chip covered with the test compound. The protective substance will be recognized as successful if it begins to blacken over direct fire not earlier than in 20 seconds. When the flame is diverted to the side, the test sample should not smolder. Metal, galvanized surfaces and concrete also require a certain level of protection. To prevent the burning of metal frames and air ducts, use "Plasas" - a fire retardant compound specially developed for this purpose.

Practical tips

In order not to worry about the appearance of the walls, after application of the impregnation, the means providing the control tinting of the surface are used. Sometimes the formulations are even before application, they are dyed. Treatment with fire-retardant composition of different sites in the house can mean different in structure and quality of the substance. The composition suitable for walls, is not suitable for exterior decoration due to the difference in street temperatures. For the application of impregnations on the facades of houses and their external elements use special fire-retardant antiseptics, capable of preserving their properties at temperatures up to -25 degrees. Such chemicals can serve for a long time.

Professionals rush to the rescue

A person who wants to protect his structure from fire, it may seem that he himself will cope with the choice, testing and application of impregnation. However, it's not for nothing that all the compositions are subject to compulsory certification, and organizations that professionally provide services to the population have licenses. Choosing a fire retardant for wood, you can simply get confused, so why not trust the experts? Chemicals are such a dangerous thing that, protecting from fire, can, in turn, harm the health of the household.
