In the modern market, in addition to classic fixing materials, you can find adhesives in a large assortment. The technology of their use is very simple, according to their characteristics they are no worse, and in some cases even better, compared to traditional fasteners. The chemical composition of the adhesive can be divided into synthetic and natural compounds, among the latter, vegetable, animal and mineral. If you are interested in synthetic mixtures, then you should pay attention to polymer and inorganic adhesives.
Varieties of building glue by drying method
Construction glue can be attributed to one of five basic types, each of which differs in the method of drying. For example, PVA and CMC are glued together with a dry residue after evaporation of water. The second type is contact adhesive, which acts by evaporation of a volatile solvent. Polyurethane compounds act on the principle of exposure to moisture, which is present in the material and air. After the molten glue cools down, the hot melt adhesives of the same name are able to act. At the molecular level, bonding is carried out with molecular mixtures.
Type of glue depending on the area of use
Construction glue can be designed for use in a certain area, depending on this, these compositions are divided into parquet, ceiling, wallpaper, and floor. In the latter case, you can work with carpet, linoleum and other similar decorative coatings. If you plan to carry out certain repairs, you should purchase glue that has a special purpose. Specialists are not always advised to use universal formulations, since a wide area of use may indicate less impressive strength and the ability to destroy bonded materials.
Adhesive for flooring and its technical characteristics
If you need building glue that can strengthen the flooring, then you will choose a composition made on the basis of synthetic resins. These mixtures are characterized by high strength and are environmentally friendly. They are resistant to temperature fluctuations, easy to use and economical. Among such compositions, parquet ones should be singled out, the main component of which is PVA. This component is characterized by high fire-fighting qualities, and also has a relatively low cost. This product does not contain volatile substances, solvents, is characterized by ductility and exhibits cost-effectiveness. If you need building glue for parquet, which has frost-resistant qualities, then you should choose a mixture of special purposes. It is able to withstand temperatures up to -300 degrees without losing its original properties.
Composition and main features of the "Bon" R-777 parquet adhesive
The manufacturer of building adhesive for parquet Bona R-777 is located in Sweden. The consumption of this material can be 800-1200 kilograms per square meter, application should be carried out using a notched trowel. Full drying will occur in 24 hours, but it is recommended to develop the composition in 90 minutes.
The mixture is intended for any wood species, any specially prepared surfaces can be used as a base. This environmentally friendly material is a two-component polyurethane elastic adhesive, which quickly reaches its ultimate strength. The surface will need to be prepared, it should be as flat as possible, strong and dry, there should be no organic compounds on the basis. Consumption can be increased if the surface is not sufficiently even.
Features of the application of glue "Bon"
Before using this composition, it is necessary to warm it to room temperature. For this, the mixture is brought in a day before the start of work in the room. Before use, the components are mixed until they reach a uniform color and consistency. Parquet work must begin under certain conditions, when the air temperature is greater than or equal to 18 degrees, while humidity should not exceed 70%. The surface of the base must also have a certain temperature, which is equal to or greater than 15 degrees.
Glue is applied evenly to the surface. After mixing with the hardener, you should try to develop a prepared composition within the mentioned time. During this period, the bonded material must be laid and fixed in its final place.
Adhesive for ceiling and walls
Construction adhesive, the types of which are described in the article, can be intended for the installation of ceiling and wall panels. It is excellent for gluing plastic, drywall or wood products. The rough foundation may be brick, concrete, wood or cement.
These compositions of the above group can be used inside residential premises, in this regard, environmentally friendly materials are used in the production process. These materials are versatile, so they can be used to glue panels to any surface. The product has a high initial strength, and bonding is achieved in a relatively short period of time.
Characteristics of Penosil Fix Go Adhesive
This construction adhesive, the technical characteristics of which is liked by most buyers, is capable of gluing panels of MDF and PVC. In this case, it is not necessary to use a crate or a frame system at all. The composition is polyurethane, and also has sealing properties. The hardened mass has excellent soundproofing properties. Among the characteristics should be highlighted quick drying, the ability to use at low temperatures, excellent adhesion, reliable mounting on uneven surfaces, as well as resistance to the spread of flame.
This composition is made in Estonia, and for 750 milliliters you will have to pay 320 rubles.
Wallpaper glue
Construction glue, the photo of which you will find in the article, can be intended for gluing wallpapers. The most popular among Russian consumers are powdered formulations, which are semi-finished products. They must be prepared before use. Less widespread wallpaper glue, which is made by foreign manufacturers. However, there is not much difference between the finished and dry formulations, but the first one is more expensive.
Characteristics of wallpaper adhesive "Methylan"
Wallpaper glue should be made in accordance with GOST 30535-97. The composition “Methylan non-woven express premium” mentioned in the subtitle is intended for single-layer wallpapers that are made on a smooth non-woven basis. Among the ingredients should be highlighted antifungal supplements, as well as modified starch. It must be carried directly to the wall, and it will be ready for use 3 minutes after preparation. The composition is compatible with cement and lime.
After gluing the canvas wallpaper can be cut directly on the wall. The manufacturer of this glue is located in Germany, it guarantees the shelf life of the composition for 48 months. Before purchasing a product, you should familiarize yourself with the flow rate, which will be the limit of 150 to 250 milliliters per square meter. After cooking, you should get a homogeneous, viscous, smooth, translucent mass.
GOST and characteristics of universal PVA glue
Universal building glue is most popular among consumers. With it, you can restore fallen finish coatings during operation. The mixture is made according to GOST 18992-80. Among the characteristics, it is necessary to highlight the high adhesive ability, which is 450 N / m. It should be noted frost resistance, low consumption, explosion and fire safety, high elasticity of the obtained joints, as well as the lack of fragility after drying.
Glue joints will be able to undergo without loss of quality characteristics about 4 cycles of freezing and thawing, they are stored for about 6 months. You should be interested in consumption: it is equal to 100-900 grams per 1 square meter. Such a big run-up is explained by the fact that craftsmen can carry out works of various types, where materials of a certain absorbency are involved.
The glue will reach full hardening in 24 hours. It is non-toxic, characterized by water-repellent characteristics, and also allows you to work with gaps, the thickness of which reaches several millimeters. The composition of PVA construction glue includes emulsions of polyvinyl acetate, water, special additives, as well as plasticizers.
Conclusion
If you decide to use universal building glue, the GOST of which was mentioned above, then you can glue any decorative finish with it at any time. However, for repair and construction work, it is best to choose a composition that has a special purpose.
