Dry mixes for building applications

The number of the currently proposed dry mixes in the hundreds, and the amount of advertising information about them, perhaps thousands. However, objective information on quality of dry mixes to find quite difficult. Leaders in quality and prestige are imported blends. And they - the leaders of engineering and technology. True, and among foreign manufacturers, there are significant differences: the Scandinavian and German quality incomparable, such as Turkish or Bulgarian. For imported mixtures should produce professional domestic producers received, usually with the use of imported equipment and technology. However, according to our producers, the mixture "in no way inferior, and by selected characteristics even surpass" the foreign, as used in the production of imported additives, advanced technology, quality control, etc. No doubt the fact that domestic mix more cheap. But - alas, many builders claim that the quality of Russian blends are still unstable, and essentially depends on the party. So, not to be mistaken as a dry mixture, one should go to a good - a large, long running and respected - building shop. That's where products are "natural selection": a solid trade organization, caring about their image, will not offer the products with which consumers have a problem. Whether the indoor parquet, ceramic tile or plank linoleum - in any case they require flat ground. It was such a ground is provided through self-leveling leveling floor. Principle of such floor is clear from the title: thick solution spreads within acceptable limits and hardens, forming a flat surface. For floors use a dry mix of cement-based additives, which provide the necessary strength, viscosity, hardening time. This may be reinforcing fibers, which improve the strength of surface tension and kink. Sometimes manufacturers offer devices for self-leveling floor system consisting of several kinds of mixtures. It's a mixture for rough alignment: filling gaps, voids, etc., and poured into already formed a frozen surface finish of the usually more subtle and expensive. Another option is a combination of mixtures - the use of one of them for manual sealing of cavities and crevices, before pouring the final mixture. Special case - compositions for the repair of stairs and sealing cracks, chips, uneven, bare accessories. Typically, such mixtures are used in small quantities, they are durable, wear resistance, high adhesion to the repaired surface. In general, the use of dry mixes for the same sex: training grounds, mixture preparation, bottling and hardening. All recommendations and requirements - how much to water, how long the mixture will be ready for use, etc. - are set out in the instructions from the manufacturers. The total in all the following instructions. Surface must be clean of dust layer sites. Sometimes in order to prepare the base for pouring is recommended to apply a primer (primer), which reduces the water absorption base that increases grip with the solution. For the same reason it is recommended to moisten. If used as a reason the old wooden floor, it can be applied to reinforcing mesh. The instructions are given, and parameters such as the recommended thickness, temperature and time of suitability of the solution. These recommendations should not be taken lightly. For example, if intended for use in a thin layer of the mixture will be poured with a thick layer, the surface may freeze before the inner layers and break through when trying to enter the seemingly solid plot. It is not recommended to use "Thick" thin layer compositions: it dries too quickly, that is not conducive to strength. Important as the temperature at which the mixture can be used: as a rule, it is room temperature, but in unheated premises can cause problems. Should be no drafts, sunlight and other factors that may lead to uneven drying of the mixture and, consequently, the cracks on the surface. Nor can overheat the water used for mixing, so in hot water mixture clutch quickly, not having properly spread on the floor. One of the best mixes for floors - a mixture of ABS Grosso, the production company "Optiroc (Finland). The mixture was used as a leveling layer for subsequent coating of the final device of any type. An important advantage of the mixture - quick setting that allows you to walk on the surface within 2-4 hours. ABS Grosso is suitable as a basis for direct laying of the finishing, as well as an underlayment for the final mix ABS Pronto. Among Finnish products and Screeds Scanfloor ("Skanmiks"), with their help, you can also hold the floors in the rooms with different requirements - they will be durable, resistant to abrasion. Domestic self-leveling floors are a number of brands: Glims, "" Plitonit "," Petromiks, etc. Mixtures for Repair of stairs makes St. Petersburg enterprises ASTC "Alita". Get rid of the "wet" plastering help "sheetrock - drywall. But the usual technique of plastering work is not a thing of the past. Perhaps, in many respects it was due to the development of production of plaster mixtures. Their benefits in the plaster case is undeniable: you can adjust the viscosity and setting time, to create textured surfaces, etc. A careful execution of instructions necessary when working with mixtures of dry plaster. We should add that for high-quality repairs using decorative plasters should be simple special tools for applying the mortar, leveling. Base under the plaster should be dry, firm and free from dust, dirt, oils, fats, etc. The smooth surface before applying the plaster coating supply the "notch". To lay down a layer of plaster qualitatively, sometimes base recommended to moisten with water or primed. Plaster can be applied as a putty knife, and a special spray (it's always stipulated in the instructions). The first layer is usually applied to a thickness of 4-5 mm, follow - up to 7 mm. If the wall surface has significant irregularities, we can put a few layers of composition (each subsequent layer is applied after setting the previous). For a full treatment of surfaces using steel ruler, with which the surface leveled. To make the surface more smooth, slightly dried up layer can be wiped with a damp sponge. One example of high quality products presented on the Russian market - plaster Rotband produced by "TIGI Knauf. The material is a single-layer adhesive plaster on gypsum-based, the most suitable for plastering walls and ceilings hand. A mixture designed for use on conventional solid foundation (brick, concrete, etc.) inside the premises. Its consumption is 8,0 kg / m 2 at a thickness of applied layer of 10 mm. From one bag of powder (30 kg) obtained about 38 liters of finished solution. Interesting and Production Company "Atlas" (Poland): the plaster composition - a good foundation for the application of finishes of gypsum, mineral or acrylic plasters. A solution of cold-and waterproof, so it can be used for decoration in unheated rooms. Manufacturers recommend to determine the amount of water, based on the desired consistency of the solution. With one package you can do about 1,6-1,7 m2 of plaster. Solution is suitable for use within 4 h. An important place in the fine finish occupy decorative plaster, with which you can receive a variety of textured surfaces. Such compositions are applied to the prepared layers of plaster, then rubbed with special tools: Depending on the method of rubbing and fractional composition can be different surfaces - "bark beetle", "rustic, rough, etc. Fillers are widely used in the construction and repair work. This is a thick viscous mass that is used to fill irregularities and smoothing the surface. Typically, fillers in the binder contained plaster, varnish, cement or glue. Usually putty mixtures packed up in smaller quantities than plaster and floor fillers: in packages of 3 or 5 kg. Filler mixture is applied with a spatula perpendicular to each other. Surplus putty is removed and then re-use. If you want to align in multiple layers, before applying the next layer, make sure the previous coat is completely dry. Example filler for plasters - Ceresit CT 29, from a respectable family of German dry mixes Ceresit manufacturing concern "Henkel", Germany. Caulking is presented in packages of 5 and 25 kg. Material consumption is 1,8 kg / m 2 wall thickness of 1 mm. Putty allows you to repair the cement and lime plaster, filling cracks and grooves on the walls and ceilings. To align the walls and ceilings in dry, damp and wet rooms and outdoor applications can be used putty mixture of cement-based Plitonit-K. It can be used with concrete, aerated concrete, the masonry or lime-cement plaster. Produced a mixture of white, super-white and gray colors. A special family of cements available for use with plasterboard (Gyproc, Knauf): this mixture is allowed to plug the gap and the traces of fasteners in the plasterboard, providing an ideal surface. Generally, dry mixes - very expensive, therefore application of quality products to tens of kilograms of plastering work or self-leveling floors are not equally shared. More cost-effective mix - dry adhesives, mortars for laying covering materials. Among the dry mixes for tiles, there are two major "families" - for laying and grouting between ceramic products. The most important parameter of a dry mix for paving - carrying capacity. The fact that now facing materials used vary in weight from a few kilograms to tens of kilograms, and that mix that successfully keeps the tile, it may be powerless in front of the granite slab 25 mm thick. Should pay attention to this parameter masonry mixes, like setting time. Another important thing - whether the mixture used for wall and floor veneer, or "specialized" for only one of these directions. Working with marble tiles or other coarse-grained rocks, you must use a special mixture, in particular, this can be found among the above-mentioned German mixtures Ceresit. When using conventional mixtures may change the color and appearance of paint over the stone. When laying tiles on the walls of the base should be firm and smooth, free from dust, dirt, lime and paint residues. Large irregularities should be corrected by using putty. If the surface has the property to absorb water, it is desirable to apply a primer emulsion. Preparedness, Primary coated base with a notched trowel applied adhesive solution, if possible in one direction. Do not apply too much solution on the surface, as it retains its adhesive properties, on average, half an hour. The larger the tile, the larger should be the size of "teeth" on the spatula. For laying floor tiles adhesive solution is applied to the prepared surface of the base. Then, with a smooth float, carry a thin layer in contact with the ground well. Solution is applied to fresh contact layer corresponding to notched trowel, and such a quantity that, during the 30 minutes it was possible to put tile, it is placed on the solution and is easily pressed to the ground. Important nuance floor stowage - no air bubbles in the adhesive mixture: after drying the voids under the tiles themselves will be given a break in the lining. Therefore, as a rule, the solutions for laying floor tiles are bred more elastic. At the top of elasticity are adhesives for ceramic tiles that allow you to pack a layer of tiles over the old layer of cladding. These compounds exhibit very good adhesion and provide a clutch lining, even with glossy surfaces. Dry mixes for the tiles are almost all the leading manufacturers - and among the "Vetonitov" and "Tserezitah", and "Atlas" and other manufacturers. It should be noted St. Petersburg family Plitonit dry mixes, the title is an allusion to the basic "specialization" of these mixtures. As part of Plitonitov besides leveling compounds and compositions for sex, are also represented: a mixture of Plitonit A - for interior use in dry and wet areas; Plitonit In this and for outdoor work, as well as for swimming pools; Plitonit C allows to lay natural stone tiles on ceramic tile and painted with waterproof paint surface. An important aspect of tiling - finish surfaces whose temperature is constantly changing (fireplaces, stoves, etc.). Without delving into the nuances of differences between tiles on a tile, just a good idea to consult with specialists. Information for consumers: a dry mixture on the basis of clay masonry stoves and fireplaces in the family is represented Vetonitov. Application of grout (fugovok) for joints between the tiles can improve its waterproofing properties, improve the appearance. It is important to know when choosing a grout: tolschinushva what they can cover, whether you can use them in locations where a reliable waterproofing. Grouting is performed after hardening solution, which laid tile, ie 1-3 days after completion of tiling, or may be formed cracks. When applying the mortar joints must be clean. After drying the grout can be sanded surface resulting cotton cloth. One of the important properties of the grout mixtures - the color, blending in with the color after installation. The system Sopro ("Stern", Germany) presented several different mixes to fill intertiled seams. Mixture Sopro MFs allows you to fill the seams with width up to 5 mm, it is available in 25 colors. Mixture Sopro MFs + b allows you to work with stitches from 3 to 20 mm in width, it is represented in 10 different colors. When using tiles on elastic foundations are recommended flexible grout. Such grouting process seams on deformable foundations, such as a flexible partition walls, heated "floating floors", etc., such as grout Ceresit CE 37, which allows you to embroider stitches width from 4 to 15 mm. With regard to overhead work, the special mixes for them, perhaps, does not exist. To work with ceilings apply wall compositions, which is usually indicated in the instructions to them. Mixture used for ceiling work, must have good adhesion and a thick consistency. With their help, can be performed plastering work: repairing small defects in the ceiling before painting or papering, plastering, gluing and finishing materials. One of the common tasks for putty - sealing cracks in the junction between the ceiling. To plastering to ceiling with dry mixes, to be used quick-plaster. One of them - a dry mixture of M-150 (Knauf), which can be used to work in both heated and unheated in the premises. Mixture Rotband the same manufacturer is a single-layer adhesive plaster on gypsum-based, suitable for hand-plastering walls and ceilings, designed for use on conventional solid foundation (brick, concrete, etc.) inside the premises. When using glue mixtures should pay attention to their "carrying capacity" in the reconstituted state. When it comes to glueing polystyrene ceiling tiles, or "health" of a mixture is easy to verify by experiment and if it is taping the ceiling wallpaper, it should only apply this glue, in the statement which indicated the possibility of using for ceiling work.
