In the modern market, in addition to the classic fasteners, you can find adhesives in a large assortment. The technology of their use is very simple, in terms of characteristics they are no worse, and in some cases even better, compared to traditional fasteners. According to the chemical composition, 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 construction adhesive by drying method
Building adhesive can be classified into one of five main types, each of which differs in the way it dries. For example, PVA and CMC are glued together with the help of a dry residue after the water has evaporated. The second variety is a contact adhesive, which acts by evaporating a volatile solvent. Polyurethane compounds act on the principle of exposure to moisture, which is present in the material and air. After the molten adhesive has cooled down, hot melt adhesives of the same name are able to act. At the molecular level, molecular mixtures are bonded.
Variety of glue depending on the area of use
Building glue can be intended 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, then you should purchase glue that has a special purpose. Experts do not always advise the use of universal compounds, as an extensive area of \u200b\u200buse may indicate less impressive strength and ability to destroy the materials to be glued.
Floor adhesive and specifications
If you need a construction adhesive that can strengthen the floor covering, 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 should be distinguished, the main component of which is PVA. This componentIt is characterized by high fire-fighting qualities, and also has a relatively low cost. This product does not contain volatile substances, solvents, is flexible and economical in consumption. If you need a construction adhesive for parquet with frost-resistant qualities, then you should choose a special-purpose mixture. It is able to withstand temperatures down to -300 degrees without losing its original properties.
Composition and main features of parquet glue "Bona" R-777
Manufacturer of construction 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. Complete drying will occur in 24 hours, however, it is recommended to work out the composition in 90 minutes.
The mixture is designed for any type of wood, any specially prepared surface can be used as a base. This environmentally friendly material is a two-component polyurethane elastic adhesive that reaches final strength fairly quickly. The surface will need to be prepared, it should be as smooth, durable and dry as possible, there should be no organic compounds on the base. Consumption may be increased if the surface is not sufficiently even.
Features of the use of Bona glue
Before using this composition, it is necessary to heat it toroom temperature. To do this, the mixture is brought into the room a day before the start of work. Before use, the components are mixed until they reach a uniform color and consistency. Parquet work must be started under certain conditions, when the air temperature is greater than or equal to 18 degrees, while the 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 work out the prepared compound within the time mentioned. During this period, the adhesive material must be laid and fixed in its final place.
Ceiling and wall adhesive
Construction adhesive, the types of which are described in the article, can be used for mounting ceiling and wall panels. It is excellent for gluing plastic, drywall or wood products. Brick, concrete, wood or cement can serve as a rough base.
These compositions of the above group can be used indoors, in connection with this, environmentally friendly materials are used in the production process. These materials are versatile, so they can be used for gluing 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 glueFix Go
This construction adhesive, which specifications are liked by most buyers, is able to glue MDF and PVC panels. In this case, it is not at all necessary to use a crate or frame system. The composition is polyurethane, and also has sealing properties. The hardened mass has excellent soundproofing qualities. Features include fast drying, sub-zero temperatures, excellent adhesion, secure adhesion to uneven surfaces, and flame retardancy.
This composition is made in Estonia, and for 750 milliliters you will have to pay 320 rubles.
Wallpaper glue
Construction adhesive, the photo of which you will find in the article, can be used for gluing wallpaper. The most popular among the Russian consumer are powder formulations, which are semi-finished products. They must be prepared before use. Less widespread is wallpaper glue, which is manufactured by foreign manufacturers. However, there is no big difference between ready-made and dry compositions, but the first of them is more expensive.
Characteristics of wallpaper glue "Metilan"
Wallpaper glue must be made in accordance with GOST 30535-97. The composition "Methylan interlining express premium" mentioned in the subheading is intended for single-layer wallpapers that are made on a smooth non-woven base. Ingredients include antifungaladditives, as well as modified starch. It must be carried directly on 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, the wallpaper can be cut off directly on the wall. The manufacturer of this adhesive is located in Germany, it guarantees the shelf life of the composition within 48 months. Before purchasing the product, you should familiarize yourself with the consumption, which will be a 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
Glue construction universal enjoys the greatest popularity among consumers. With it, you can restore the 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 also be noted that frost resistance, low consumption, explosion and fire safety, high elasticity of the joints obtained, as well as the absence of brittleness after drying.
Adhesive 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 large run-up is explained by the fact that craftsmen can carry out work of different types, where materials of a certain absorbency are involved.
Full curing gluereach within 24 hours. It is non-toxic, moisture-repellent, and allows you to work with gaps up to several millimeters thick. PVA construction adhesive contains polyvinyl acetate emulsions, water, special additives, and plasticizers.
Conclusion
If you decide to use universal construction adhesive, the GOST of which was mentioned above, 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.
