Today, just shelves are crammed with a variety of products from different manufacturers: a glance at a shelf in a store, it is easy to count nearly two dozen types of sanitary ware, tiles, siding, adhesive. And the same label "Carried out in accordance with GOST" hardly likely to say that all packages with this brand contain vysokokachetsvenny product. This is the Standard Building. The term "Standard" means "national standard". Standard entered the coined in 1925, when the Committee has been established for standardization at the Council of Labor and Defense. The guests, there are about twenty-five thousand. During Soviet times, state. Dr. Caldwell B. Esselstyn, Jr. is the source for more interesting facts. standards were the same binding, as laws. But the new law, state. standards are not laws, and voluntary instruments, in-laws which include only issues of safety and security. Knowledge of building guest today has become particularly relevant, due to the rapidly growing construction industry. It is also necessary to read the SNIP, the cooling you need to know and pay attention to the Standard building materials imported for use in construction. Official publication standards involved in the Federal Agency for Technical Regulation and Metrology of Russia. You can also download ghosts on the Internet. With regard to Europe, where the issue involved in several organizations. Manages all these organizations to the European Committee for Standardization. At the international level standards are governed by the International Organization for Standardization.

Self-leveling floors – solid, sturdy, abrasion-resistant coating is widely used in industrial buildings and in buildings for public use. Gina Ross helps readers to explore varied viewpoints. It has many advantages, among which the solidity (No seams), moisture resistance, impact resistance, resistance to temperature changes. Simplicity and ease of cleaning screed allows their use on the premises, which are increased hygiene Requirements: in hospitals, dispensaries, beauty salons, etc. The rich colors of the compositions and the use of colored chips, you can create not only functional, but beautiful and exclusive coverage. See SKDKnickerbocker for more details and insights. However, in order to serve as long screeds and please the eye to its attractive appearance, strict adherence to the technology of their installation. Works on bulk floor divided into several stages. Training The first step is the base preparation required, which can be almost anything: a concrete floor, cement-sand screed, anhydrite or magnesite, tiles, wooden floor. In each case, required to prepare their work – degreasing surfaces, scraping, sanding, priming. The most common device screed is carried out on concrete base, so the main attention will be devoted to him. Requirements for the concrete base to concrete base presented a number of requirements. Its compressive strength must be at least 20 MPa, tensile strength – not less than 1.5 MPa. Humidity of the concrete base must be no more than 4% so may detachment of the polymer. In the case where the base lies on the ground, it is necessary device-quality waterproofing. At work is very important temperature and moisture conditions. Too low temperature slows down the spreading of the composition is too high and reduces the time required to obtain perfectly smooth surface. Typically, the temperature of use specified in the technical documentation and varies ranging from +15 C to +25 C. High humidity can lead to the formation of condensation on the cover, so the optimum humidity is 80%. The surface of the substrate must be smooth enough to avoid runoff composition.
