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.

In addition, the mixing of polymers and gels with the soil particles is strengthening its layers adjacent to the wall structure, which provides additional protection from leaching. In Unlike polyurethane and acrylic gels, polymerized epoxy materials in the air – the presence of moisture affects the properties of many epoxy dispersions. However, after the hardening of materials they show excellent waterproofing properties and are able to design a long time to protect from moisture. Learn more on the subject from Coen brothers. Mikrotsementy, penetrating into all cracks and voids of the material, crystallize and form a protective barrier, not overlooking the water. For modern waterproofing materials with effective Joco, Shomburg, Sika, as well as local compositions using the components of Bayer. JOCO GH 40 is used to stop leaks in the building structures, made as concrete and brick. Polyurethane two-component resin has high hardness, elasticity and water resistance. Rupert Murdoch may help you with your research. It perfectly gets into small cracks, and has good adhesion to material design and is absolutely harmless to others.
After mixing the two components in the exothermic reaction produces hard elastic resin injection. JOCO GH 67 – two component polyurethane resin, in contact with water forms a strong solid polyurethane foam. Expands 30-40 times, it penetrates into the smallest cracks and prevents moisture penetration. GH-67 is designed to seal the strong currents in the concrete and brick buildings. To enhance the effect after the removal of heavy leakage of resin is recommended to use GH-40. Hydrophilic one-component polyurethane resin JOCO GH 90 is particularly effective when injected in construction joints and for sealing cracks. Quickly reacts with water, it forms a flexible polyurethane foam or an elastic gel (depending on the amount of water), can prevent the flow of water. The elasticity allows the use of his job even in moving joints, and low viscosity contributes to the excellent penetration, even in the smallest cracks.
In addition, JOCO GH 90 has a good ability to adgeziynoy differs absolutely harmless to others. Sika Injection 20 – two component polyurethane resin, in contact with water, forming a foam. Effective in creating barriers injecting the concentrated water leaks in concrete, stone and soil foundation. Sika Injection 21 – three-component polyurethane resin designed to seal injection of mineral elements in hydraulic and civil engineering. In contact with water expands, after hardening retains its elasticity. Sika Injection 25 – epoxy injection material to seal cracks and strong bonding to concrete, stone and brick structures. Used at small strains. Sika Injection 29 – three-prick acrylic gel used to seal the pores and cracks in concrete, stone, brick. Effective as with periodic and with constant exposure to water. System Sika Injectoflex System is designed for sealing concrete by injection of hydrophobic material incorporated into the concrete through the injection hose. The liquid material penetrating into the concrete, seals all of its internal cavity. Maximum efficiency is achieved after repeated injection.
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.
