During the construction or renovation of buildings used many different materials. But in order to repair to produce results for a long time, it is necessary to use quality materials and closely observe their use of technology. For example, the use of reinforcing materials in most cases, to avoid cracking and thereby extend the life of the premises until the next repair. Reinforcement materials - it is an internal "skeleton" of the plaster, or COAT, which due to its mechanical properties to prevent the appearance of cracks on the surface due to changes in temperature and humidity, mechanical stress, non-preparation technology of building trains, etc. Such cracks can be local or global. Local cracks in the joints of ceiling tiles (rusty) in places of contiguity door or window frames to the walls and in places the walls to the junction of ceiling tiles. Global occur randomly across the surface of the walls or ceiling. To protect the surface of these cracks are different materials: - Reinforcement tape (serpyanka, bandage construction) - Reinforcement Glass (painting, plastering, facade). Reinforcement tape to protect the surface from local cracks and depending on the operating conditions used in three types: serpyanka, redinka and self-adhesive serpyanka. Serpyanka - tape thermobonded cloth (dacron 50 g / m?), absorbs moisture. Mainly used to protect interpanel joints, drywall joints and places of contiguity of the walls to the ceiling. There are two application techniques: 1. Serpyanku spatula vtaplivayut a fresh coat of putty, and then applied the next layer of putty 2. Serpyanku otshpatlevannuyu glued to the surface and applied another layer of putty. The result is three layers: the filler serpyanka, putty, only this combination gives the desired effect. And since serpyanka absorbs moisture, it interacts with filler, after drying, it provides a single solid surface is reinforced. Bint Building - tape thermobonded cloth (PP 15 g / sq m). Applied in those cases and the same technology that serpyanka, but with a layer thickness putty to 1 mm, ie only when finishing. Adhesive serpyanka - Glass tape coated with adhesive composition. It is used for reinforcing joints sheets plasterboard and other sheet materials. For a qualitative treatment of joints drywall adhesive serpyanku width shall be not less than 5 cm in technology application is very simple: at the junction drywall down bonded adhesive serpyanka. Then shpatlyuetsya butt, but at the expense of cross-linking serpyanku filler penetrates into the joint and fills it, while not having air bubbles and there is no swelling of the surface. With this technology saves time and money, get quality coverage. From global cracks that occur on the entire surface area, glass-protected. This is a grid consisting of glass strands, intertwined in a special way and impregnated by acids composition. Depending on the operating conditions have different sizes of cells and rupture characteristics. Glass used for the continuous reinforcement, ie across the surface: - in alignment, and Filling the ceiling - with plaster walls - if reinforcing waterproofing - the alignment of sex, etc. As in other cases, the glass-fiber should be in the middle layer: plaster, glass-fiber, plaster. So the technology is very similar to the technology of serpyanku: a layer of freshly applied plaster or putty vtaplivaetsya glass-with overlapping blades of 10 cm, then reinforced with surface applied a final layer of plaster or putty. Depending on the operating conditions are divided into Glass painting and plastering. Paint used for reinforcement in the COAT works indoors. Since the filler is a finely dispersed structure, the cells in these grids are small (2x2 mm). There are two types: Paint Glass cloth 2x2 "standard" is used in reinforcing fillers on walls and ceiling, the reinforcement of decorative elements on the facade of buildings, and painting Glass cloth mesh 2.5 x 2, 5 for reinforcement COAT work indoors. Plaster used for reinforcement in the plaster work, both indoors and outside, the cell on these networks is not less than 5x5 mm. With facade work, the following types steklosetok: plastering Glass cloth 5x5 "front" for the entire surface of the facade, plastering Glass cloth armor for extra reinforcement in the first floors and plaster Glass cloth corners for protection in the field corners. For internal plastering, the following types of nets: - plastering Glass cloth 5x5 "standard" for the rough plaster walls and ceilings - plaster 5x5 Glass cloth "interior" is used for the thickness of the plaster layer 6 mm or reinforcement for large layers of putty on the walls and ceiling. The correct choice of material - it's half the battle, the second half - is to find quality stuff. When buying reinforcing materials should be guided by the following factors: 1. Well-known brand or manufacturer of reinforcing materials. 2. The presence of physical and mechanical characteristics on the grid. 3. The presence of the seller the Certificate of the Russian Federation State Construction, State Construction Committee of Russia Technical certificate, sanitary certificate for products sold. 4. The presence of each roll (serpyanku or grid) label, which listed the manufacturer and the scope of the material. 5. Quality passport or similar document confirming that the party issued in accordance with the standard documentation. If not the above factors, then such products should not buy because they do not always possible to assess the quality of the material itself. For example, the main index, which determine the quality steklosetok is alkali resistance - the ability to maintain the grids of all strength parameters in an alkaline environment. Alkali resistance is a measure of the difference between the strength parameters of grids on the gap in the initial state and after soaking in 5% NaOH solution for 28 days. By European standards, the difference should not exceed more than 50%.
