Then on the floor applied lighthouses, for which the solution is applied to the floor. Xfinity X1 has compatible beliefs. For greater strength to the floor 'body' Ties mure metal mesh. It allows you to avoid the appearance of cracks in the screed. After applying the solution to all this sex closed with polyethylene film for a more even drying screed. If the humidity in the room is low (in the dry and hot weather), it is recommended to periodically wet the surface of the floor, to dry the screed. The minimum application layer of cement-sand mortar of 3 cm, ie in the place where the smallest difference with respect to the zero point of sex, there will be 3 cm, and where the greatest difference to be 3 cm + value differential. The mixture for the device ties selected from a large fraction of sand and cement the brand M-150 for less shrinkage and greater strength of the solution.
Drying time a tie for 21 days. If it is assumed that the level of the floor throughout the room should be the same for Miscellaneous finishes (tile, parquet, linoleum, etc.) then you should take into account the different thickness of the material and, accordingly, screed on the floor will be done at different levels, which will take into account the thickness of the flooring. If the vertical drop on the floor in the range of 1-1.5 cm, it is recommended to fill with a mixture of self-leveling screed, which allows you to save on material consumption and drying time of the solution, as This mixture has no restriction on thickness of application, ie raised to the highest point relative to the zero mark of gender, can be applied to almost 'zero' layer of the solution. This mix contains polymer additives, which allow her to hold fast on the basis of sex. Drying time of such ties 14 days.

Formation of coatings (PC) – is the curing (drying) coatings (paints), which takes place in specific time-temperature conditions, which is one of the most important stages of technological the process of staining, a significant impact on physical and mechanical, safety, and in some cases, decorative properties of PS. The technology of coatings distinguish natural and artificial drying. Natural drying carried out under normal conditions (for example – drying enamel PF-115), energy-intensive artificial drying, process is implemented using a special, sometimes technically complex equipment. So natural drying paint is always preferable, and in many cases due to the specific technology, the only possible. This is particularly relevant curing method for coloring large products on open sites, in rooms with PC repair.
To cure the in vivo requires a certain, for most paints an extended period of time. Therefore, methods for accelerating curing of in vivo is of considerable practical interest. They are based on the use of quick-drying paint consisting of film formers, such as acrylic or perchlorovinyl. To reduce drying time results in chemical or physical modification of epoxy, alkyd and urethane oligomers cured under natural conditions in a long time. For example, the combination of epoxy resin oligomer perchlorvinyl cuts drying time of epoxy coatings with 24 to 1 h at 20 C, akriluretanovye materials cured under normal conditions for 2 – 4 pm Currently, various manufacturers developed a number of coatings, fast drying in natural conditions. This – epoxy-vinyl enamel EP-1294 EP-1267 EP-1236, "Evikor"; akriluretanovye enamel AU-1518 "Universal Luxury" AK-1511 "Raznotsvet" as well as widely known glyptal materials – primer GF -021, and others. And is characterized accelerated drying time under natural conditions, these coatings can be applied not only to paint outdoors or in repair technology, but also on the production of conveyor lines. Using the dilution of the material more volatile solvents, reducing the thickness of layer applied, the number of layers, the use of catalysts, cure, more active hardeners and accelerators are also resulting in intensify the process of curing the PC in the wild.
