For the construction of baths and saunas, wood is traditionally used as building material and as a finish material. Even if the material for the construction of the bath is a brick, then the interior decoration is made of wood. This choice is due to the qualities that the tree has. These include: Ecological purity. Durability. Sufficient thermal insulation. Ease of processing. However, there are factors that lead to the destruction of such convenient material. The main reasons lies in the structure of the bath or sauna. Let’s look at what negative factors affect wood inside the bath: increased humidity. Sudden temperature differences. Pathogenic bacteria. Given these adverse conditions, to preserve the appearance and performance of wooden products in a bathhouse and a sauna, additional care should be done. First of all, you need to make the right choice of wood breed, from which the finish should be made in the bath. But it is worth taking into account the fact that any breed of wood is exposed to negative influences and cannot forever resist. To increase the service life, the tree is impregnated with special compositions. Such processing carries quite a lot of protective functions and allows the use of wood for a long time. The choice of impregnations that can prevent harmful effects is quite large. The main parameters for wood processing compositions are in environmental purity and non -combustibility. Various types of impregnations are widely used, which are based on the oil structure. Most of these impregnations are made on the basis of wax and very well protect the wood from harmful factors. We should not forget that not only the interior decoration of baths and saunas needs additional processing, but also the external walls. Only in the case of the outer walls of the impregnation should have other qualities. The most important necessity is to warn the bath from the possibility of fire. Therefore, compounds that have refractory properties are used for external wood processing. Such compounds are not recommended to be used for processing indoors because they have a large number of chemical compounds. Using the impregnations in the construction and operation of baths and saunas, you can significantly extend their service life.
