Fire protection of wooden structures. Fireproof impregnation of wood

A tree is the most common building material. It allows us to design almost any design, create an atmosphere of coziness and warmth. In addition, wood is a natural material that positively affects human health. However, there are cases when such structures are endangered. For example, in case of fire. Therefore, fire protection of wooden structures is a desirable procedure.

Is it necessary to protect the wood in this way?

The answer is unequivocal - yes. Even the simplest treatment increases the resistance to burning. At the same time, you not only protect your house from destruction, but also insure your own life. And a small expenditure on flame retardants will save considerably more money in case of fire.

Fire protection of wooden structures can cost differently. Everything depends on the type of the selected product, its properties and manufacturer. In order to make the right choice, you should first understand the classification of fire retardants and the features of their use.

Advantages

Before you will be made fire protection of wooden structures, you need to consider its advantages:

1. Relative cost of processing. What price you would not have to pay for a tool, it will cost you less than a ruined house.

2. Wide choice of means. And both by types of application, and by properties. That is, different designs can be processed by different compositions.

3. Easy to use. Fire protection of wooden structures can be done by hand. This will also save your money.

4. High efficiency. In the event of a fire, your designs may become charred, but will not light up.

5. Wide accessibility. You can purchase the required composition in any construction shop.

Processing tasks and the scope of its application

Before fire protection is provided, it is necessary to find out exactly where it can be used and what it should provide. The main tasks of the procedure are:

1. Protection of wooden structures from fire.
2. Cessation of the spread of open fire.
3. "Passive" localization of the fire at the very beginning, that is, without the use of any additional means.

Fire protection is applied for almost all structures made of wood:

1. Roof rafters .
2. Floor and walls, both inside and outside.
3. Lumber, which are designed for storage in warehouses.

In principle, such protection is used both in private and in multi-storey construction.

Types of funds

Now let's look at the classification of the substances:

1. Fire retardants. These chemical compounds serve to prevent fire of wood. They are phosphate and swelling. Their peculiarity is that during heating they form a film and inert gases that absorb excess heat and do not give oxygen access to the source of ignition.

2. Lubricating materials. They consist of a binder component, often inorganic (alabaster, lime or clay), as well as refractory filler (mica, asbestos). In order for the fire to be prevented, such a material should be applied in a thick layer. Naturally, this method has one drawback: the surface has no decorative appearance.

3. Fire-retardant paints. These funds are applied to the tree in a fairly thin layer. This creates a film of 1 mm, which when heated to high temperature has the property of foaming and blocking the access of oxygen to the structure. The same characteristics are available and varnishes, but they do not spoil the appearance of wood. On the contrary, they can significantly improve it.

4. Impregnation. In the composition of these funds, it is possible to note both organic components and combustible solvents. Therefore, you should take care when working with them. Fire-retardant impregnation for some time can stop the spread of fire.

5. Combined substances. They can effectively protect the tree not only from ignition, but also from pests (beetles, rodents and others).

This classification is the main one and makes it possible to determine precisely with the means that will suit you most.

How to choose a substance?

Before the fire protection of wooden roof structures or other parts of the building is carried out, it is necessary to purchase a suitable composition. So, during the selection, pay attention to such criteria:

• The ability not to affect the appearance of the structure being processed. Here everything depends on your needs. For example, fire protection of wooden roof structures can be any, because it is not visible in the rooms where you are constantly, and does not spoil their appearance.
• Means must be allowed for indoor use. That is, it should not contain any toxic elements that can cause health problems.
• Fire protection should not degrade the natural properties of wood.
• Please note that the funds presented may have a negative effect on metals.
• Naturally, attention should be paid to the consumption of the composition for 1 square meter. It depends how much money you spend.

Naturally, you should buy it only at certified points of sale. Each composition must have the necessary accompanying documents, confirming its quality.

Useful tips for use

In principle, you can use the funds presented almost everywhere. However, there are certain caveats:

- Do not apply to wet or frozen wood. This will not give the proper effect.

- Do not cover the surface that has already been painted with other paintwork materials.

- Fireproof impregnation for wood can not be used for application to other types of building materials (metal, concrete, brick, plastic).

- It is possible to carry out fire protection work only in the warm season.

Features of application of composition

First of all, remember that work should be in protective clothing, so that impregnation does not hit the bare parts of the body. The fact is that it can cause a burn or other damage. Before you start, you need to collect the necessary tools. Here everything depends on the type of fire protection. For example, you can use a conventional brush or sprayer. You can also apply a normal dive for a short period. However, these methods do not provide deep impregnation.

It is best to apply soak methods. This will ensure deeper penetration. Naturally, this method is more time-consuming and time-consuming.

It is necessary to apply the product with observance of the consumption rates. Before this, it should be diluted according to the system specified in the instruction. This will ensure the effectiveness of the substance indicated in the instruction. Do not work in rainy weather.

Before applying varnish or paint, the structure should be cleaned of debris and dust. If there are any irregularities, then they need to be treated especially carefully.

How often should the funds be used?

Fireproof impregnation of wood should be made periodically. The fact is that the service life of the impregnation can vary from 1 year to 30 years. The coating should be inspected once every 12 months, if the structure is open, and at the next repair, if it is closed.

If the surface of the wood is chipped, peeling off or flushing the protective coating, and they occupy more than 25% of the area, then it is required to repeat the application. Try to use the same remedy that was used before. If you bought something else, then you need to check the compatibility of these two substances. And it is better to remove the old layer of fire protection altogether.

That's all. Impregnation with fire retardant composition of wooden structures can one day save your life. Try to be careful. Good luck!
