Questions and answers

Many people consider that treatment of the substrate by primer is not required. And the worst of all, when so considers those who are employed to. Treatment of the surfaces by primer is not only necessary but it is obligatory! By using the primer, we are strengthening substrate, bonding the dust, increasing adhesion with overcoat layer of plaster, adhesive mortar and etc.

After mixing dry-set mixture with water, it must be exposed for 5 minutes in order to dissolve all chemical additives included in the dry-set mixture during this time. After aging, the so-called "maturation" of a mixture, mortar must be mixed thoroughly again with low-speed drill with paddle-mixer, correcting the consistency of the mixture. Thus, all of the chemical additives will be activated. If you do not expose 5 minutes and do not mix again the mixture then the mortar properties specified by manufacturer will strongly be reduced.

No. First of all, it is to follow the manufacturer's instructions, in which recommended ratio of ANSERGLOB EG 61 with water is 1:6. By mistake some people believe that if the emulsion will be diluted 1:2, then they will get more efficient primer. In this case, glossy layer of polymer film is appeared, on which application of plaster or paint will be difficult.

The main application of this emulsion is priming weak water sorption substrates such as concrete, sand-lime brick, front part of the cladding tiles in order to increase adhesion. ANSERGLOB EG 62 used in the exterior insulation finishing system ANSERGLOB for temporary closing-down of the facades for winter period. Besides, ANSERGLOB EG 62 is recommended for applying as undercoating of decorative plaster. In these cases, the adhesive emulsion must be tinted in similar color of the finishing coating.

Excessive addition of water to the mixture leads to delaminating of all the area of screed (segmentation). If you value quality of the coating, then it is required to follow all manufacturer's recommendations about application of this material, as well as to comply with the proportion of water to the mixture. As a result, you get a strong covering which will last for a long time.

Screed is an intermediate smoothing layer, which serves to level the surface of the underlying layer or framework, for distribution of stress on the sound insulation layers, for giving to the coating the specified slope and covering the heating elements.

After 28 days all the basic processes of shrinking are passed, and the screed is gaining the standardized strength specified by the manufacturer.

No, it is not. For cladding the tiles on the drywall surface it is recommended to use ANSERGLOB BCX 44. So this dry-set mortar unlike ANSERGLOB BCX 33 is elasticized and durable to periodic deformation (atmospheric pollutions and dynamic stress).

Filler fraction of dry-set mixture is 0,63 mm. In order to discover the high adhesive strength of the mixture to maximum, the layer thickness must be three times larger of filler fraction, i.e. 2 mm.

Freeze-thaw stability is the ability of a material to withstand a water-saturated state of reusable alternately freezing and thawing without significant loss of strength and mass. Characterized by cycles of freezing, one cycle is equal to one freezing and thawing.

In order to EFIS functionates for a long time, you must take care of correct installation of insulation boards. After 3 days of bonding insulation boards to the wall, you must make an additional mechanical fastening with special rawplugs, since the adhesive mortar acts on shear and rawplugs on tear off. According to quantity and arrangement of rawplugs you must follow the requirements of “Technological map of installation of exterior facade insulation system of buildings and structures using materials ANSERGLOB” or DSTU B V.2.6-36_2008 "Facade insulation".

Extruded polystyrene (XPS) is completely non-permeable, so because of it the application in insulation systems is limited. It is recommended to use extruded polystyrene for insulation only the socle of the building. And bonding this insulation board must be provided by bitumen based adhesives. However, it can be used in EFIS, but if the building has good mechanical ventilation. It should be noted, that surface of XPS is excessively dens. Therefore, when applying extruded polystyrene board as heat insulating material before bonding to the substrate, both sides of its glossy surface must be sanded mechanically. The cost of such XPS is high and its usage in insulation systems is not economically advisable.

To strengthen the adhesive layer on the surface of the insulation boards the facade mesh made of wicker glass fiber must be used, forming cell 5x5 mm, with the factory impregnated anti-alkali coating. The mesh significantly increases the mechanical strength of waterproofing layer which protects the insulation panels from external influences and is the basis for applying the decorative layer. The mesh must be resistant to alkaline medium of waterproofing layer. The density of the mesh for the basic reinforcement should be not less than 145 g/m². (Recommended 165 g/m²).

No, can’t. To avoid the appearance of cracks in the finishing layer of plaster applied to AAC the mixture with high water-holding capacity must be used. Otherwise, AAC, having a porous structure, will sorb all of the water from the topcoat. In the future, all the plastering coat will fail to gain standardized strength and will crack. For this type of work masonry mortar ANSERGLOB BCM 12 can be applied, which suits for laying and plastering of the surface from the heat insulating cellular concrete, such as concrete, foam concrete, gas silicate, etc.

By adding modified fillers in the composition, the bulk density of the mixture is decreased. This results in an increase in volume of the mixture. So, the standard bag contains 15 kg only. Due to this composition, we are gained the simplification in the plastering work.

Product consumption, specified in the catalogue, is obtained in the laboratory and is intended for preliminary calculations. Causes of product overconsumption at a construction site can be a lot: it's bad leveled wall surfaces, multiple loss of mixture during application, using of low-quality tools for the job, a violation of technology application and forming of the structure, and etc.

If you do not protect surface of mineral plaster by additional paint coating, there is the risk of efflorescence - white salt-lime deposits on the surface of the facade. Such efflorescence appears because of water entering in watrproofing finishing layer, it washes out unbounded lime and various salts. Even if all the materials are bonded (which is virtually impossible), falling rain on the wall, polluted by gases, contained in the atmosphere, has a slightly acidic reaction, which also promotes the formation of such salts. It loses the esthetic look of the facade. In order to ensure there is no efflorescence and to strength finishing of the facade, you must paint it surface.

We recommend to tint adhesion emulsion ANSERGLOB EG 62 if we plan to use it as undercoat before applying decorative plaster with the corrugated texture "Koroiid". It is required when forming corrugated texture of plaster, in the areas where appears furrows applied white adhesive emulsion will not be visible. This tinting is required only in the case of already tinted plaster. If you use mineral plaster with the corrugated texture and plaster layer then is painted by facade paint, the tinting of the adhesive emulsion is not obligatory.

The thing is that usually the builders do not wait, when all the layers are carefully hydrated and dried. In the autumn-winter season it is also a high humidity of the ambient air. Thus, in the thermal insulation, waterproofing and finishing layers the excess moisture presents, even when it seems that everything is dry. If it is applied acrylic plaster or paint, then due to the very low vapor permeability of acrylic products in the substrate moisture is conserved and more moisture is coming out on both sides of the acrylic coating additionally saturates substrate. Later, when severe frosts occur, especially on a clear sunny day, the wall is heated, at this point the difference between the partial pressure of water vapor is maximal and increased migration of accumulated moisture from the insulation system to the atmosphere is taken place. Because of the acrylic layer can not cope with moisture transfer and it is detached from the substrate. Therefore, in such cases, it is better to apply silicone paints and plasters. And also it is possible to apply cement based decorative plasters ANSERGLOB.

For cladding the socle, you can apply all kinds of tiles made of natural, artificial and cast stone. And you can insulate the wall. The best of all it is carried out by the extruded polystyrene board. For finishing coating decorative acrylic mosaic plaster ANSERGLOB labeled "SOCLE" suits, that is durable and can resist to all adverse atmospheric factors and to abrasive the resulted of the rain, reaching the finishing coating. In addition mosaic plaster is washable by water.

Yes, it is an integral part of the finishing coating of mosaic plaster ANSERGLOB, if it is applied outdoor. If the plaster is used indoors, then treatment by acrylic lacquer ANSERGLOB ES 86 is optional.
