When carrying out most of the construction work today, foam is used , which are made by different manufacturers. However, one of the most popular is Technonikol, which is known to the consumer for its quality products. It has been present on the market for a long time, during which time it managed to become a leader in its field.
An example of the material mentioned above can be TechnoNIKOL adhesive foam, which has a wide range of uses and has outstanding characteristics.
Description
TechnoNIKOL glue-foam is intended for fastening of expanded polystyrene and extruded polystyrene sheets to the base when installing thermal insulation to the internal and external walls of buildings, foundations, roofs, floors, and cellars. This material is used for new and reconstructed buildings. Glue-foam can be used for temporary fixing of XPS and EPS boards to vertical surfaces indoors. These include balconies, loggias and interior partitions.
Additional area of use
To warm the facades of the slabs, they are also quite often fixed to vertical surfaces, the described adhesive foam will help. When warming foundations and socles, as well as when sealing gaps between insulation boards, Technonikol adhesive foam is used, it adheres well to various materials.
Composition Consumption
TechnoNIKOL glue-foam is characterized by excellent resistance to aging, moisture and mold. It adheres well to cement plasters, concrete and other mineral substrates. High adhesion is noted with chipboards, wood, and OSB boards. As for consumption, we can talk about cylinders of different volumes. If this parameter is 750 ml, then its volume will be enough for an area limited to 10-12 m 2 . A cylinder having a volume of 400 ml will go onto a coating of 4 m 2 .
TechnoNIKOL glue foam is also consumed depending on the weight of the binder. In a large container, its content is 600 g., While in a small - 260 g. Given that the degree of evacuation of the binder from the cylinder is 85%, then the flow rate for cylinders of different capacities is not a multiple of the volume. Use of this composition is necessary with a limited temperature range in the range from 0 to 35 ° C.
Key Benefit Reviews
If you still have not decided whether to buy TechnoNIKOL adhesive foam, then you should familiarize yourself with the reviews, from which you can find out the main advantages of this material. Among them, consumers distinguish:
- ease of use;
- reduction in time to complete work;
- low consumption;
- minimal secondary expansion;
- excellent resistance to aging, mold and moisture;
- reliable and fast fixation;
- low thermal conductivity.
Mounting method
TechnoNIKOL glue-foam should be used according to a certain technology. The cylinder must be installed with the valve up on the base, then the protective cap is removed, and the valve must be aligned with the gun seat. As soon as the cylinder is installed in the gun, it should be shaken vigorously. Before installing the plates on the surface, it is necessary to install a fixing profile, and the first row of insulation material will rest on it.
It is necessary to apply the composition in the cylinder position up, the distance between the stove and the gun must be maintained, only then will the mixture be applied correctly. It is necessary to deviate from the edge of the slab about 2 cm, then apply foam in separate strips, the width of which should be 3 cm. Through the center of the slab, stretch another stripe, the distance from it to the long sides should be equal on each side.
When TechnoNIKOL glue-foam for polystyrene foam is applied to the surface, it is necessary to wait about 5 minutes, waiting for the full expansion of the composition. The material is fixed on a vertical surface. The plate is installed in place, it is necessary to put a little pressure on it. The plate is fixed until the mixture sets. Cloths should be installed close to each other, it is necessary to observe the spread of the seams. A gap should remain between the webs, the width of which does not exceed 2 mm. TechnoNIKOL adhesive foam allows you to adjust the position of the panels over a period of time from 5 to 20 minutes after installation, everything will depend on environmental conditions. In order to exclude the formation of cold bridges, larger gaps should be filled with scraps of polystyrene foam, as well as adhesive foam.
Physical and mechanical characteristics
You may be interested in some of the technical specifications of the material described above. For example, the evacuation rate of the contents is 85% or more. The polymerization process will begin approximately 15 minutes after application. The mixture hardens in 2 hours if the external air temperature is 20 ° C and the relative humidity does not drop below 50%. Full cure time is 24 hours, but no more. After completing this step, the density of the material will be 25 g / cm 3 . If you purchase TechnoNIKOL 500 universal adhesive foam, you may also be interested in the thermal conductivity of the composition, it is 0.035 W / mK with a concrete surface. The adhesion strength is 0.4 MPa, with regard to expanded polystyrene, the adhesion level is equivalent to 0.09 MPa.
What else you need to know about TechnoNIKOL glue foam
Before applying adhesive foam, the surface must be cleaned of dust and dirt. If you want to accelerate the curing process, as well as provide better adhesion, then the work surface is pre-moistened. Shaking the container before use should occur within 30 seconds. If excess glue has arisen, then you can get rid of them with a foam cleaner of the same manufacturer.
When the glue dries, it should be protected from direct sunlight. TechnoNIKOL adhesive foam, the flow rate of which was presented above, must be stored in a vertical position, while the temperature of the external air can vary from +5 to 35 ° . The conditions must be dry. Lowering the temperature to -20 ° C is acceptable, but under such conditions, the cylinders can be stored for 1 week or less. Do not use the composition after the warranty period of storage, which is 12 months.
TechnoNIKOL glue-foam, reviews of which are often only the most positive, can be transported by any means of transport, the height of the cylinders must be folded in one row. For transportation, you need to choose covered vehicles.
Conclusion
Glue-foam has a wide area of use. It can be used for the installation of gypsum board and expanded polystyrene boards. You can use the composition in residential, public, as well as industrial buildings, apartments and private houses. This mixture can become part of the elements of walls and partitions.
Plaster, concrete, wood, and chipboard can act as a coating surface. After hardening, thermal stability varies from -60 to +100 ° C. At 23 ° C, film formation will occur in 8 minutes, with a relative humidity of 50%.
