Self-leveling screed (this monolithic flooring, running from mobile samorastekayuschihsya polymer-sealant on pre-prepared base or screed. Depending on the type of resin, the compositions are divided into epoxy, polyurethane, acrylic (PMMA-based) and polyester. By changing the composition, varying the thickness coating can be, depending on the requirements for the coatings are abrasion-resistant, durable, elastic, decorative and durable coating with a number of specific qualities: quiet operation, chemical resistant, hygienic, easy care and others. - Epoxy (based on the reactive groups), self-leveling floors are used in areas with tyazhelogruzhenym transportation, travel, corridors for trucks, etc., that is to be exposed to considerable mechanical stress. minimal shrinkage, good adhesion to the ground floor, the mechanical strength and high resistance to chemical attack allows you to use epoxy resin as a binder for devices such floors. The most widely used two-component epoxy water-soluble composition. - Polyurethane poured floors are resistant to abrasion, mechanical and chemical (especially acids, oils and gasoline) exposure. These floors are slip resistant to the action of bacteria and fungi, have no smell. Polyurethane composite formulations represent two, sometimes three-component system containing the basis of reactive oligomers, modifiers, curing agents. products based on polyester resins for solid flooring (resin + fine-grained quartz sand). Curing time - a few hours. The surface of the solid floor and dry, allowing the next day walk on it, ride the lifts, etc. These floors are characterized by high hygienic (no pylyat, environmentally friendly). Acrylic mass is used for device self-leveling floors in kitchens, dairies, in grocery stores, office premises, etc., for objects that are possible effects of chemicals on the floor (especially acidic). Floor coverings of plastics masses often layered with a thickness usually ranges from 0.5 mm to 2 mm. If the flow of such compounds at 1 m2 floor surface - 0,3 l / m 2, such a floor rather be called colored than tankers. To make the high decoration to the surface (varnish) layer is introduced mosaic cereal. Optionally matches the color and shade, a corresponding picture or ornament. Process sequence of the device coatings self-leveling floor for a finished bottom: vacuum dust removal - Primer - Putty - the basic layer - lacquer. Following the solidification of the base layer of putty sanded carborundum stone (grinder) and cleaned from dust, then primed. Primer secures the top layer of the base, strengthens dustable particles in the pores of the base, provides a strong connection to the ground floor of the film. primer applied spray gun with a thin even layer, avoiding the formation of puddles on the ground surface. The prepared base coat is applied after drying the lining layer of mastic (the first operation to fill the floor) . Second (front) layer of the floor is applied to the dried first. The second layer of mastic more than fat, for rapid aging is necessary to ensure good ventilation when the air temperature + 12 ° C + 25 ° C - in the operation can be administered in 5 - 7 days. Water-soluble composition after hardening does not dissolve in water. The final operation device flooring - is covering it with lacquer. The first time varnish, as the adhesive dries (becomes solid), the second time - finally, together with a decorative filler - chips - the next day. Varnish forms a strong hydrophobic film which prevents penetration of moisture and specks of different indentation in the floor covering. Epoxy resins have high strength values ??that they attach to the materials on their basis, the maximum toughness - 18,5-20 KpaM. With an average annual traffic of pedestrians wear in mm: - epoxy putty and varnish 0,1-0,15 - 0,15-0,2 polyester - polyurethane 0,05-0,1. The total thickness of the coatings self-leveling floor is determined depending on operating conditions: Residential - 2 - 2 5 mm, the public - 2,6 - 3 mm.
