Lumber / | Protection of wood |
Before a person who is going to build a country house, a cottage or a country house, one of the first question arises: what to build? The most natural and environmentally friendly, but also not the most expensive stuff — tree. The building, constructed out of it, the person feels most comfortable. But the tree has a lot of disadvantages, among which there are quite objective: it burns easily and is subject to the action of fungi, bacteria, mold, etc. Therefore, since ancient times tried to protect the wood from both the flame and from decay, insect pests, and the actions of other external factors.
Where are those same mold and fungus?
Almost from the air — fungal spores and bacteria only need to get to the favorable conditions to start its dirty work. Wood can mold already during transport or during storage prior to construction. Imagine this common situation: — Materials bought in the spring, and the building is postponed until August. For a better safety, many covered with wood and polyethylene wrapped as tightly as possible — not to leaked moisture. It was then formed and treacherous greenhouse — Grace for mold. Rule one — wood must be ventilated and during storage and have built the house. If we talk about the finished buildings, the mold loves all wet and stagnant air — damp corners of the rooms and especially the cellars.
Protect the tree, you can use special substances — antiseptics. Traditional methods such protection — This wood treatment solution of copper sulfate or potassium dichromate — simple and available reagents. It certainly gives some protective effect, but it changes the color of the wood and also unsafe. Vitriol — poison, and potassium dichromate — a strong oxidizing agent, which must be handled with gloves.
Modern household chemicals for wood protection are very diverse. For a long time, perhaps only existed in the sale of the Finnish vehicle was « pinotex » alkyd-based with minor antiseptic additive. This was a warning to the bank, which in the process of applying can not breathe fumes. This is inconvenient and dangerous, so now, as on the shelves of a wide range of wood protection, the most attractive antiseptics, which are harmless aqueous solutions.
It is not necessary to wait until the tree can be exposed to mold, the material is better to treat as soon as he comes to the consumer, without waiting for the start of construction. A few years ago it was believed that antiseptics are only able to prevent the loss of timber. Recent domestic developments, such as the company « Lovin », can also treat wood-destroying. Once processed by modern means, wood is resistant to fungus and decay for at least ten years, and after re-processing — indefinitely.
Earlier woodwork was the work of professionals. Now, this process was very simple and accessible to everyone. Simply apply the solution onto the surface of the tree any tool — roller, brush or spray. It is also possible to dip the material into a solution, but it is not very convenient, also difficult to determine how much active substance remains in the solution.
Most revolting has antiseptic activity against wood pests, but does not destroy them. But there are special compounds that kill borers, bark beetles, longhorn beetles, burrowers and other bugs destroyers, usually alcohol-based. Processing technology is completely different, because the pests are taken deep into the solid wood. The fluid with a syringe or pipette is pumped into the flight holes Zhuchin mink coat with surface and near these holes.
Notice damage to wood is a snap: dark spots, gray patina, raw wood ... Wood, began to rot, and even do not need to describe. As a rule, woodwork is made in the construction, but it can also happen that the house has already been built, and the defense did not apply. If the tree has not been painted with oil paint and covered with varnish, processing, certainly will result. Otherwise, the antiseptic solution is simply not absorbed into the solid wood. If the damage appeared only in some areas, it is not necessary to handle all of the walls and floor, enough to remove plaque and mold and cover the drug only to the affected areas.
The worst enemy of wood — white house fungus. He successfully masquerades as a common mold, and at first it is able to distinguish only professionals. But this is only as long as the fungus does not show character. Under certain conditions, this month it is capable of « eat » entire oak floor thickness of 4 centimeters! No wonder that in the old hut, where the plant a mushroom, burnt immediately, so as not to infect other buildings. Until recently it was thought that it is impossible to resist, and that recently the researchers have found that anti-white fungus brownie effective treatment of a third brand of domestic antiseptic « Woody healer ». But this is only the results of laboratory tests.
So it makes no sense to read in an old book retseptik, diluted vitriol to impregnate wood. If not less, but more reliable and safer to turn to the achievements of modern household products. In the next issues we will continue this theme and talk about the protection of wood from the fire.
