Restrict the construction of even a high-quality home is not enough. It is necessary to think about the upcoming protection of wooden surfaces of all structures using lag, i.e. impregnation, on which finishing canvases are laid, whether it be the floor or the roof. If this is not done, the tree will rot over time, keep bark beetle clutches in it, and also suffer when the humidity is higher than expected, for example, due to battery leaks or heavy rains.
The lags for a residential house should be treated with environmentally-friendly impregnations that will protect the wood from moisture and various pests.
Now that it has become clear that impregnation for better preservation of wooden buildings cannot be avoided, the question arises: how to infiltrate floor logs? There is no definite answer, you need to disassemble in more detail. First you need to decide on the purpose of the floor in the room: a residential building is a bath or terrace, open and closed.
The composition of the impregnation and its safe application depend on where the lags are used.
For bath lags, you should choose an impregnation with the inscription "for the bath and sauna", which has an increased water resistance.
It is worth knowing that the durability of impregnation lag is directly proportional to the type of wood. Coniferous trees contain resin, which only enhances the water-repellent qualities of impregnation, but they cannot be used in baths. Inhalation of the needles does not heal - it only works with brooms steamed according to the rules. Therefore, for different gender requires a different tree.
When purchasing wooden building materials, you should not flatter yourself, even if the manufacturer assures quality drying. This may be true, but there are still storage conditions, and storage rooms often do not meet the requirements of ventilation. After bringing materials to the construction site, you need to dry them thoroughly again, then the impregnation of the lag with chemical compositions will be much better.
It is better to use antiseptics on a bitumen or silicate basis, but strictly in accordance with the purpose of the marking.
It is necessary to pay attention to the quality of draft floors. That is, on the surface, where lags spread. If it is a concrete base, then impregnation should be abundant and in several stages. Concrete does not let water through, so possible leaks on such a floor will linger for a long time until they evaporate in a natural way. This process can cause the rotting of the lower parts of the lag, and the floor will not last long. If the foundation of the floor is a layer of soil or sand, then one should not be afraid of the accumulation of moisture: it will simply go away.
Lag thickness. It is necessary to make it moderate so that the floor does not fail, and the impregnation penetrates as deeply as possible. The depth of a good impregnation should be 3-15 mm, therefore, the thickness of the lag exceeds this value by at least 10 times.
Ventilation. The most important condition for the preservation of the floor. If you do not make it sufficient, no impregnation of floor lags will not save. Enough air cushion between the draft and finishing flooring in 5-10 cm. By the way, the logs themselves should not lie on the bare floor, ground or concrete.
Antiseptics. Preparations preventing the occurrence of mold and fungus. They are the most toxic in comparison with other impregnations for the lag. Their use is conducted with extreme caution, according to the label for the intended purpose. Silicate compositions, bituminous and clay, are more popular in everyday life.Some of them can be cooked at home to protect yourself and others as much as possible.
In order for the logs to have fire-fighting properties, they must be impregnated with flame retardants.
Flame Retardants. These compounds include boric acid, phosphates. Lags treated with this composition have fire-fighting properties. When the temperature on the surface rises, the chemicals melt and form a protective film that prevents the fire from burning. Fire safety - an important point in the impregnation of wood lag;
Protection against biological organisms: fungi, bugs. Antiseptic should be labeled that way. If in the process of building parasites was not observed, this does not mean that they are not. They can insidiously arise after several years of operation at home. Organisms have the intimidating ability to completely “eat up” wooden structures, including logs. If the house has a characteristic smell of mushrooms, then you have to lift the entire structure of the floor, in order to make sure that the existing damage.
This is done only if the careless owners did not bother with the impregnation of the lag from the very beginning of construction. However, not all antiseptics can cope with the resulting fungi and bugs. In this case, you need to process the lags as much as possible, replace the elements that have been damaged. The main thing - to find the epicenter, laying eggs.
In Russia, the huts, subjected to mold and fungi, were often simply burned. Now, of course, this is impossible, so you have to work with your hands. Damaged places are either completely replaced or cleaned with sharp objects: a knife, sandpaper. After that, everything peeled off, including paper, is burned.
The lesions are washed with a solution of hydrogen peroxide or potassium permanganate.
And then the floor and lags are copiously treated with impregnations. All these actions do not guarantee the complete destruction of biological parasites, but ignoring the application will cause an even greater percentage of destruction.
Many home builders do not use modern products, but use proven "old-fashioned" methods. Such impregnation, for example, can be ordinary oil and its waste.
You can make a wonderful impregnation for wood by yourself: mix one liter of water with a glass of vegetable oil and an antiseptic.
It is not recommended to use a machine: its smell can last for a long time, irritating everyone around. An emulsion is prepared on the basis of vegetable oil - a liter of water + a cup of oil + an antiseptic.
This composition is aged, agitated, then lags are impregnated with it. Some craftsmen use homemade mastic - oil + wax. Such compositions are expensive, but very reliable.
But in the case of protection from beetles and mushrooms, they are not suitable, unless wax is replaced with bitumen on the floor, which, when heated, gives the smell of impregnation of railway sleepers, which is unacceptable in residential premises.
Wood - a beautiful material, environmentally friendly, durable, but defenseless. To make its beauty long not only possible, but necessary — there are a lot of ways to do this.
The choice of impregnation for the lag is huge, and if all the above conditions are met, the floor supports will last a long time.
