What is and what is the ognebiozaschita wood with their hands ?

The design of any building, regardless of what materials it was erected, there are certainly elements made of wood.More often than not because of her settling truss system, various types of base plates (lathing), door and window openings.And the floors, walls, stairs?Yes who knows what else.

growing popularity frame construction has caused an understandable interest in individual developers to question ognebiozaschity.Wood from time immemorial considered a universal construction material, because it has many advantages.But there are significant drawbacks to consider.Features of the application is that any "wooden" preform must necessarily undergo special treatment.Why?

What does need protection from rot

Wood, regardless of breed, can absorb moisture.With varying intensity, but wetting leads to the appearance of mold (mold), the development of a variety of bacteria.

insect

Various zhuchki- "carpenter" for a short period of time can turn wood into dust, furrow any part of the construction tunnel-strokes.And they "work" regardless of the season, and because of them, but to impregnate the material, no.

from contact with the atmosphere

swings humidity levels and temperatures lead to the fact that the wood cracks.And the stronger the effect is, the more often have to deal with repairs.A UV light not only speeds up the process, but also leads to darkening of the surface, which is not the best way affects the appearance.

From fire

The fact that the wood is classified as flammable materials, is known to all.No need to explain why you need protection from thermal effects.

When the question is raised about the most effective means ognebiozaschity, you can often hear the recommendation with reference to the "wonderful" import tool.And here, it seems, requires some explanation.In pursuit of bright labels and catchy titles, we sometimes forget that our "Chemical School" in the days of the Land of Soviets was considered one of the best in the world.

can not believe that it does not have the tradition continue.Moreover, many foreign advertised compositions created on the basis of our development.How they get there (for "hill") were, is another question.But the fact remains, and it will not deny the serious professionals.

How do you know what kind of structure?It is necessary to carefully examine the code consisting of letters and numbers.That's it and you need to pay attention in the first place.

How to "decrypt»

«B»

It means a substance containing boric acid.It gives, above all, and flame retardant properties.

«D»

also protects against fire, since the thermal effect as a result of a chemical reaction timber is covered with a kind of film.

«M»

Typically, this bluestone.It is both a good defense, and of the ignition, and fungus (mold).It has long been considered a folk remedy to combat mold and rot.

«C»

Refers soda (soda).Her close "kinsman", potash, enjoyed "authority" in firefighters.Considered one of the best ways to protect against fire (impregnation of a 40% solution).

«F»

With such compositions should be careful.Sodium fluoride - a poison.Waster to mold and bugs.

«X»

poisonous substance.Is poison for "carpenter".

«HA»

feature of such compositions is that the strong increase in temperature, they emit a gas that prevents the spread of flame and reduces it to nothing.

Note that many of the commercially available drugs are effective only as long as the dry wood.The fact that an increase in humidity, some components simply "washed out", therefore, reduced, and security material.It is therefore advisable to use paints and tools.

Alkyd

differ good efficiency, but there is a significant disadvantage.They are characterized by a surface effect, as it does not penetrate deep into the structure of the material.

Enamels, nitrovarnishes, epoxies

same properties as that of alkyd compounds.However, do not give an antiseptic effect, therefore, considered to be more fire protection means.

paints (enamel) acrylic

Typically, diluted with water.After drying forms a protective film.According to experts, imported products are much more expensive than Russian, while the quality is often inferior to domestic funds.

Practical advice

• Any preparation to protect against biological pests in varying degrees contain poisonous components.It is therefore necessary not only to observe extra care and prevention measures in their use, but also to ensure proper storage of security.Access to these children and pets should be completely excluded.

• effectiveness of any composition is largely determined by the conditions of its application.What wood is processed (dry or wet), in any weather, and so on.Therefore disposable impregnation usually does not result.The majority of funds are designed to handle it well dried preparations.Be aware of this, otherwise this type of work simply makes no sense.

experts recommend protective measures for at least 2 times with an interval of 30 minutes to an hour, and then, if the work is dry and the processing is carried out at a normal level of humidity and a temperature of at least 18 0 C!For other conditions (if permitted by the manufacturer), the number of "reps" must be increased.

• If a composition based on sodium fluoride, it is worth remembering that it loses its properties in direct contact with cement, alabaster, chalk, lime.

• When processing wood "details" that will not be visible after installation and, consequently, their appearance is not important, you can use this way - make them impregnation with a mixture of waste oil (machine), and a solarium.But the peculiarity is that the workpiece is necessary to maintain in the "solution" for several days, but then you can not paint.

unequivocal answer to the question of whether a remedy for heat-biosecurity better, can not be.Processing quality depends on the type of wood, the "process" technology, the external environment.Yes, and on the accuracy and experience of the person who does the job - too.But the most high-quality protection is achieved through an integrated approach - treatment + outer coating (paints, varnishes, mastics).

addition, has a value of quality and further "facing" when the product is wood, for example, part of the internal structure.For example, in the case of truss system, the major role played by hydro and steam.If the workpiece to be dug into the ground, then no impregnation will not help.It should also handle outside.For example, pour hot bitumen.

Conclusion

What is the composition applied, everyone decides for himself.One only has to remember that:

• first, can not be limited to only one agent;
• secondly, selected compositions should complement each other, that is to have some different characteristics.That is a quality protection will be provided;
• thirdly, the work should be carried out only under the appropriate conditions (temperature, humidity).
