Glue on all occasions, wallpaper paste, dispersion glue, PVA glue

CMC wallpaper glue. One of the oldest and most trusted wallpaper adhesives are adhesives based on carboxymethylcellulose (CMC). The fact that the carboxymethylcellulose has the temperature of coagulation, ie, when dissolved in hot water it does not form precipitation and clods. Simply put, when preparing the adhesive on the basis of the substance water temperature does not play a strong role. To understand the market CMC-adhesives is not easy, their range is constantly growing and changing. Therefore, in order not to fall for bait bungler and not buy low quality goods, we recommend that you follow a few simple rules. First and foremost: CMC-glue is a white powder. If so, then he will be glued superbly, quickly dissolve in water without forming lumps while. If I buy the glue is yellow and powder in a package instead of chips, it is a clear sign that before you produce poor quality. Especially dangerous is it for paper wallpaper, this glue can easily seep through them and their yellow spoil the appearance, moreover, it is long and poorly soluble in water. Not recommended for domestic import wallpaper adhesives, since the results can be unpredictable, there were cases when they change color, messing with the colors of wallpaper. All the errors in the selection can be avoided if you buy the adhesive well-known brands such as: "Quelyd" (France), "Dufa Tapetenkleister" (Germany), "TD 2000 (England)," Papa "(Germany), or use a glue the same brand as the wallpaper. Different adhesives on the basis of carboxymethylcellulose not only in quality but also on the intended use. There is a CMC-adhesives for light, medium and heavy wallpaper. Their main difference from each other - is the concentration of carboxymethylcellulose. The higher it is, the higher the viscosity of the adhesive. This is particularly important for heavy-wall paper, adhesive with low viscosity will not be necessary to force them to grasp and they may come off. Therefore, we must follow the rule: the thicker the wallpaper, the thicker should be the glue. For rooms with high humidity is perfect CMC-adhesive with the addition of antibacterial substances, it will prevent the process of decay. Another kind of wallpaper adhesives are vinyl adhesive. It is ideal for bonding vinyl, foam, fabric or embossed wallpaper. Also with him is very easy to work, wallpaper on the freshly deposited adhesive vinyl it slides along the surface and are easy to align and dock. If necessary, wallpaper canvas (if the glue has not dried up), we can tear off and stick again, without adding glue. Technology dissolution of dry wallpaper adhesives is the same. In the enamel, or plastic bucket poured water temperature of 25 degrees, then in the tank creates a whirlpool, into which, without ceasing to stir, and go to sleep dry mixture. Until ready adhesive must defend from 3 minutes to several hours, the time is always indicated on the packaging. Apply glue to the surface in several ways. It can be spread on a cloth and just paste, it is usually used when gluing light paper wallpaper. Or the second option: the glue is applied to the surface, then he gets to soak in the base and then another layer of plaster. Only after this wallpaper blade is attached. Typically, the procedure works with the wallpaper is described on the packaging or the accompanying instructions. For gluing velvet, textile, vinyl or glass fiber is also used dispersion adhesive. From other varieties of wallpaper adhesives it is distinguished by its high durability, wallpaper, glued on him, not so easy to tear off the wall. Another advantage of the dispersion glue is that it is waterproof and can withstand high humidity. However, it should be noted that use it in the bathroom is still not recommended. Dispersion adhesive, in contrast to the usual dry, producing a ready to use, and applied it directly on surfaces, rather than on themselves wallpaper. Glue dries so about 12 hours. Liquid nails ". This name was based adhesive aqueous dispersion of acrylic copolymer, which has been specially designed for quick and easy, without using nails, installation. On the "liquid nails" can be glued decoration materials of wood, chipboard, fiberboard, gypsum, plasterboard, cork, cardboard, until the ceramic and metal. In fact, it is a universal glue that allows finishing materials and stick to various surfaces, and glue them together. Apply adhesive to a dry, clean, degreased surface, but not a continuous layer, while the dots (if the material is easy), or snake (under the heavy stuff). The drying time of the glue - 12-24 hours, depending on the thickness, temperature and humidity. Glue on the latex-based. This adhesive is versatile and is used for virtually all types of domestic work. They are glued parquet, linoleum, ceramic and tile, and many other materials on almost all the bases. Application method is traditional: the surface should be cleaned of dirt, degrease and impose on it a thin layer of glue, then glue can be mounted almost any material. Setting time of the adhesive from 30 minutes to an hour. What can stick tiles? Ceramic tiles can be glued to the surface of an ordinary cement, the adhesive solution of cement-based, or a special paste. Clay, cement-based pastes are much cheaper, so use it at work more often. It is used for attaching tile, ceramic tiles, tiles made of natural or artificial stone, large sizes and with a pronounced relief of the back of the tile. First, the prepared surface is applied first thin layer of glue and leveled it, then applied another layer, which actually laid the tile. This "cake" is done in order to ensure maximum shvatyvaemost with the surface. Glue dries in a day, and after two more gains maximum strength. Mastic based on sodium silicate applied to the surface somewhat differently. It is placed on a flat surface a thin layer of 0,5 - 1 mm, on an uneven surface layer of mastic is placed necessary to align the surface, then lay the tile. Paste hardens after 3 hours, and finally dries up in 5-6 days. PVA glue. When repair and construction work may have to be glued wood. For this purpose, would be the best adhesive based on an aqueous dispersion of polyvinyl acetate (PVA). Any tree, he practically glues "tightly." He is able to withstand the pressure at the gap of about 100 kilograms per square meter. See Adhesives, PVA produced several species. PVA-P "is universal, they can be glued veneer, plywood, chipboard, fiberboard, just pieces of wood. PVA-M specializes in wood, veneer and particleboard. PVA-T sticks together not only the tree, but also used to add the cement mortars, because it provides a better grasp on the surface. Glue dries so quickly, and a half to two hours. Of course, this is not a complete list of all used in construction adhesives. Full details can be podcherpnut have spetsialistvov who is in any good repair and construction company.
