Wood is the most common buildingmaterial. It allows us to carry out the design of almost any design, to create an atmosphere of comfort 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 wood in this way?
The answer is unequivocal - yes.even the simplest treatment contributes to increased resistance to burning. In this case, you not only protect your house from destruction, but also insure your own life. And a small expenditure on fire retardant funds will help save significantly more money in case of a fire.
Fire protection of wooden structures can costdifferently. It all depends on the type of agent, its properties and the manufacturer. In order to make the right choice, you must first understand the classification of fire retardants and the features of their use.
Advantages
Before you make fire protection of wooden structures, you need to consider its advantages:
1. Relative processing cost. Whatever price you pay for the facility, it will cost you less than a ruined house.
2. Large selection of funds. And both by type of application, and by properties. That is, different designs can be processed with different compositions.
3. Ease of use. Fire protection of wooden structures can be made personally. This will also save your money.
4. High efficiency. In the event of a fire, your constructions may be charred, but will not catch fire.
5. Wide availability. You can purchase the necessary composition in any hardware store.
Processing tasks and its scope
Before fire protection is performed, you need to know exactly where it can be used and what it should provide. The main objectives of the procedure are:
- Protection of wooden structures from fire.
- Stopping the spread of open fire.
- "Passive" localization of the fire at the very beginning, that is, without the use of any additional funds.
Fire protection is used for almost all wooden structures:
- Roof rafter systems.
- The floors and walls, both inside and outside.
- Timber that is intended for storage in warehouses.
In principle, such protection is used both in private and in high-rise construction.
Types of funds
Now let's look at the classification of the substances presented:
1. Антипирены.These chemical compounds serve to prevent the ignition of wood. They are phosphate and swelling. Their feature 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. coating materials.They consist of a binder component, often inorganic (alabaster, lime or clay), as well as refractory filler (mica, asbestos). In order to prevent a fire, 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 rather thin layer. This creates a film of 1 mm, which, when heated to a high temperature, tends to foam and block access of oxygen to the structure. Varnishes have the same characteristics, but they do not spoil the appearance of the wood. On the contrary, they can significantly improve it.
4. Impregnation.In the composition of these funds can be noted as organic components, and combustible solvents. Therefore, you should be extremely careful when working with them. Fire retardant coating for some time can stop the spread of fire.
5. Combined substances. They can effectively protect a 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 exactly with the tool that suits you most.
How to choose a substance?
Before fire protectionwooden structures of the roof or other parts of the structure, you must purchase a suitable composition. So, during the selection, pay attention to the following criteria:
- Ability not to affect appearanceprocessed design. It all depends on your needs. For example, fire protection of wooden structures of the roof can be any, because it is not visible in those areas where you are constantly and does not spoil their appearance.
- The tool must be authorized 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 adversely affect metals.
- Naturally, one should pay attention to the consumption of the composition per 1 sq. M. It depends on how much money you spend.
Naturally, you should buy it only at certified points of sale. Each composition must have the necessary supporting documents confirming its quality.
Useful tips for use
In principle, the presented tools can be used almost everywhere. However, there are certain cautions:
- Do not apply to wet or frozen wood. This will not give the desired effect.
- Do not cover the surface that has already been painted by other paintwork materials.
- Fire retardant impregnation for wood cannot be used to apply to other types of building materials (metal, concrete, brick, plastic).
- It is possible to carry out works on fire protection only in a warm season.
Features of the application of the composition
First of all, remember that you should work inprotective clothing so that the impregnation does not fall on the exposed areas of the body. The fact is that it can cause a burn or other damage. Before starting, you need to collect the necessary tools. It all depends on the type of fire protection. For example, you can use a regular brush or sprayer. You can also use the usual dive for a short period. However, these methods do not provide deep impregnation.
It is best to apply soaking techniques. This will provide deeper penetration. Naturally, this method is more laborious and time consuming.
Наносить средство нужно с соблюдением норм expense. Before that, it should be diluted according to the system specified in the instructions. This will ensure the effectiveness of the substance specified in the instructions. Do not work in rainy weather.
Before applying the varnish or paint design should be cleaned of debris and dust. If there are any irregularities, they must be treated very carefully.
How often should the presented agents be applied?
Fireproof impregnation of wood shouldmade periodically. The fact is that the service life of impregnations can vary from 1 year to 30 years. The coating should be checked once every 12 months, if the structure is open, and at the next repair, if it is closed.
If the wood surface is chipped,peeling or washing out of the protective coating, and they occupy more than 25% of the area, then it is necessary to repeat the application. Try to use the same tool that was used previously. 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.
That's all. Impregnation of wood-based flame retardants can one day save your life. Try to be attentive. Good luck!
