Foam-cement "Makroflex" (Makroflex): characteristics, application

Foam-cement "Makrofleks" recently used by professionals and domestic craftsmen quite often, so its name can be considered a household name. This is due to the high quality of the composition and reasonable cost, convenient form of release, as well as unique properties.

Specifications

Foam cement can be used in the temperature range from +21 to +25 ° C, however the manufacturer allows use when the thermometer is between -5 to +35 ° C. If you compare with traditional assembly mixes, this indicates that you have more opportunities to work in the off-season.

Foam-cement "Macroflex" has a density that is 20 kg / m ³ . The film on the surface after application is formed after 9 minutes. The minimum value is 5 minutes. Full hardening should be expected after 30 minutes, but under certain conditions this stage lasts only 25 minutes. The volume change is 5% and can vary in the positive or negative direction. Per day, water absorption is 1% or less, whereas in 28 days this figure can increase to 10%, but not more.

Foam-cement "Makrofleks" is also characterized by good sound absorption, this parameter is 60 dB. It is also important to take into account the thermal conductivity, it varies from 0.037 to 0.40 W / m × K. After hardening, the heat resistance is from -40 to +90 ° C. Without loss of properties on the foam, a very high temperature of +10 ° C can be acted briefly.

On the adhesion strength

The use of assembly foam with the addition of cement excellently demonstrates itself when gluing wood, as well as polymers and materials from woodworking products. For example, if the timber is cemented with cement foam, the strength is 2 MPa. The same characteristics are the strength of adhesion of granite to cement. When carrying out work, when PVC and ABS plastic are used for bonding, it can be stated that the strength is 1 MPa. This adhesion is comparable to the adhesion of concrete and cement slurry.

Sometimes in the work there is a need to use materials that do not have high porosity. At the same time, the average bond strength reaches 0.3 MPa. Here you can include ceramics, glass and concrete. Approximately with the same strength indicators, the composition will bind OSB plates together. Polyfoam and bituminous coatings adhere slightly worse, with adhesion of 0.2-0.25 MPa. Less reliable foam-cement "Makrofleks" manifests itself when there is a need to glue drywall, zinc and mineral wool. If the layer of the mixture is 8 mm, then strength in the range of 0,10-0,15 MPa is expected. Therefore, these materials can only be stuck together when they are not loaded during operation.

Application area

For the reason that the field of use of the material described assumes the performance of external works, the possibility of using it at negative temperatures is a useful property. You can buy this material if you need to link building blocks with each other. The composition will also cope with fixing the insulation panels to the outer walls and foundation. Foam-cement "Makrofleks", the application of which is quite extensive, copes with the installation of staircases and is used in the installation of window sills.

Key Features

The material described can replace cement-like mixtures and cement itself. After purchase, the cylinder is fully ready for use and easy to use. With the help of foam, you can connect building materials with each other, and the composition for internal and external works is suitable.

Makroflex (foam-cement) is a building material that not only effectively glues, but also guarantees heat, sound insulation and airtightness. Use the mixture at low temperatures. Thanks to the fact that recently such an innovative product appeared on the shelves, you can refuse heavy bags, waste of energy, water, additional equipment. The work will no longer be accompanied by the appearance of dirt and dust, you will shorten the time for additional cleaning work.

The product will help to do the job with less effort and allows you to reduce the time spent. The novelty, recently issued by the company - "Macroflex" construction foam, 850 ml - eliminates the occurrence of cold bridges, guarantees high strength of joints and meets the requirements for a solution of EN 998-2. Customers choose this product for the same reason that it does not contain chlorofluorocarbon propellants.

Cost

If you needed Macroflex brand foam, the price of this product should be known to you. For the 0.85-liter balloon it is necessary to pay 450 rubles. This mixture is universal, and its weight is 0.99 kg. The product is a one-component aerosol polyurethane foam, which hardens under the influence of moisture and is characterized by its super-efficiency and versatility.

Apply the composition with a special applicator gun. "Macroflex" (foam, the price of which you already know) after drying is required to protect from exposure to sunlight, apply on the surface of the composition can be paint, gypsum, sealant or mortar. Sometimes other types of coatings are used.

Main advantages and disadvantages

The main advantage of the described assembly mix can be considered convenience of use. Foam is easy to apply, as well as simply control the amount of composition. In this case, you exclude overruns. The glue will reliably isolate the seams from moisture ingress and reduce the heat loss of the building. However, Macoflex foam cement, the characteristics of which were presented above, also has some drawbacks. They are expressed in large shrinkage, however, the foam initially is not very large volume expansion. Therefore, it will not be so noticeable to sit down.

From the high density, another minus follows, which consists in a large consumption of the composition. Before purchasing a mixture, you must calculate the required volume. Thus, one cylinder will be sufficient for 10 m ^{2 of} brickwork, the dimensions of which are 60x25 cm. At the same time, the walls will be 11.5 cm.

Conclusion

Foam-cement, which was described above, is excellent for building bridges and restoring block masonry. You can use the composition for the installation of window sills, staircases, and frames. With its help, finishing and warming the surfaces with tiles. The cost will depend on the basis from which to work. One cylinder will be sufficient for gluing gypsum panels, the area of which reaches 12 m ² .
