Tonkosloynyie plasters of new generation on an example of plasters ATLAS’a

One of the important decisions during building or house repair is the choice of a finishing layer. With complete reliance it is possible to tell, what exactly the facade (decorative front plasters of a choice quality) depends on aesthetic tastes proektanta and the investor and simultaneously represents a protective barrier of a building from atmospheric effects. Fortunately, there have passed those times when to receive a plaster solution or decorative front plasters of a choice quality, it was necessary to stir izvest, sand and cement.

Now decorative front plasters are made in the form of ready mixes which it is necessary to prepare according to with the instruction indicated on packing. Several years ago at building of one-family and large-family houses in Poland all decorative front plasters of bad quality with poor koloristikoy and the invoice were applied almost. Very often in connection with the financial reasons of a wall of buildings kept without a proper protective plaster layer or painting that led to their damage and corrosion.

And if oshtukaturivanie also it was executed, quality, durability and an aesthetic kind left much to be desired. The similar situation occurs also to the facades painted by front paints. As usually used smooth zatirku plasters, and the invoice was limited to one kind – "lamb" with the help nabryizga with application venichkov. All these factors did not promote a good aesthetic kind of a facade and depreciated the Polish architecture. However, within several years we notice significant improvement of this situation.

Together with economic changes in Poland there were materials (decorative front plasters of a choice quality) which not only did not concede import, but also surpassed them in quality. In the market there were accessible decorative front plasters or structural plasters which allowed to vary the big colour scale and invoices thanks to what facades took an aesthetic form and durability. Technical and technological progress has affected changes in surface furnish. Modern decorative front plasters of a choice quality which were characterised by high technical parametres and spetsialisticheskim appointment were even more often applied.

Development opalubkovoy technicians, accuracy of fulfilment of construction materials, and it means more equal surfaces of the executed walls, have caused necessity of opening tonkosloynyih plaster weights. Now decorative front plasters execute very important role both for furnish of the traditional mineral bases, and for systems of warmings of buildings a method "easy-wet".

Manufacturers of construction materials offer ready decorative front plasters of set of kinds and a choice quality. It tonkosloynyie mixes which guarantee to a facade an effective kind. These decorative front plasters are accessible in many colours and invoices. Except decorative character have also the protective. These decorative front plasters form a layer proof to atmospheric effect, including to light, and in particular to ultra-violet radiation, and also possible mechanical damages. In this connection tonkosloynyim to plasters very rigid demands (the parametres characterising plasters together with conducted experiences, Plaster mixes for ottenochnyih solutions ”are reflected in PN-B-10106„) are made.

These decorative front plasters are evaluated from the point of view of appearance, behaviour at temperature 5°C, consistences, working properties, morozo-shcheloche - and kislotostoykosti, colourfastness, firmness to blows and the accelerated effect of atmospheric factors, adhesion to the basis in a dry condition and after saturation by water, capillary absorption of water and diffuzionnogo resistance.

Still actually Standard principles of conservation of energy conduct warming by plaster to acceptance of the measures directed on restriction of losses of energy. In this connection the increasing quantity of investors make decision to execute thermomodernization of buildings. And so, the structure of products for fulfilment of warmings of outside walls of buildings, covers many materials which in all system execute a certain role in this connection it makes corresponding demands.

Undoubtedly, the most important thing is protection of the materials which are under a layer tonkosloynoy plasters. It is possible to assert, that a facade strong until an outside layer strong. It is necessary to indicate, that the majority of damages of a facade results from that decorative front plasters contain water under the layer. The plaster coat is subject also to effect of many outside factors and as a result these loads he grows old more fast from all warmed elements. Protective properties depend, first of all, on protection of a facade against atmospheric, mechanical, chemical effects and fire.

Easy plasters, and also warming decorative front plasters improve termoizolyatsionnyie properties of outside walls. A problem of plasters even more often is also preservation of the necessary microclimate in premises or fulfilment of special requests, for example, shielding of radio-waves, protection against x-ray radiation, protection against noise etc. Separate group make the plasters applied in restoration works.

Protecting plasters are applied to the damp and salted walls – impervious a moisture, one-and multilayered kompressnyie the plasters which are a barrier from hit of mineral salts. The main principle at fulfilment of restoration works is the principle, consisting that all blankets (decorative front plasters and painting layers) should not hinder diffusion of water steam.

At fulfilment of restoration works for the plasters used in premises, it is required, that the equivalent thickness of an air bed satisfied condition Sd
However, undoubtedly, the biggest group are tonkosloynyie decorative front plasters in the thickness of 1-3 mm stacked as in the form of furnish of traditional cement-limy plasters, and making a definitive layer in systems of warmings of buildings.

Updating of a facade of buildings is the expensive process requiring a professional knowledge. Depending on a building image, a plan proektanta or the investor and character of an updated facade it is possible to use various decisions.

Except an estimation of aesthetic qualities of plasters and others pokryivochnyih the systems applied to updating of a facade, we should pay attention to quality, availability, repeatability and durability of these products also. GROUP ATLAS products fulfil all above-stated requests, and their wide choice allows to adapt a kind pokryivochnoy mixes for each type of the basis, a kind of a facade and character of a building in which facade updating is executed.

MINERAL PLASTERS

Mineral decorative front plasters the cheapest but because they are made in the form of the dry mix requiring working out with water and stirring on building, require more expenses and time in comparison with akrilovyimi. Mineral plasters also require more condensed technological mode (a careful dosage of the water, corresponding atmospheric conditions) – especially it concerns the painted plasters.

Mineral plasters become with the course of time more and more strong, that is connected with process karbonizatsii, an event under the influence of carbon dioxide. During operation they perfectly pass check in designs in which good diffusion of water steam is necessary, and also in places without too big industrial zaryazneniya. These decorative front plasters have the big firmness to ultra-violet beams and ozone, however, in connection with the chemical character and concerning small elasticity, they less proof to mechanical damages, for example, to washing by a high pressure.

Mineral plasters are made only in light pastel colours. Alternative application for the ready painted plaster mixes is application of mineral plasters ATLAS CERMIT SN and DR, and also ATLAS CERMIT SN-MAL and fulfilment of a painting layer from recommended silicate paint ATLAS ARKOL S or silikonovoy ATLAS ARKOL N.

AKRILOVYIE PLASTERS

Akrilovyie plasters are decorative front plasters based on high-molecular polymer in the form of a water suspension. Used akrilovaya pitch, on the one hand, gives to a material the big elasticity, small water absorptivity, however, on the other hand, that is very important for this substance, process of diffusion of water steam and carbon dioxide is hindered. As a matter of fact, these parametres especially influence occurrence of drops under a plaster coat that leads to cracks and otsloeniyam from the basis.

Akrilovyie plasters have richer colour scale thanks to the contents both inorganic, and organic pigments. They are made in the form of the ready weight requiring only stirring before drawing. As a result of it work becomes easy, faster, the risk of occurrence of technological errors decreases.

Akrilovyie decorative front plasters more proof to undesirable repainting as a result of changed conditions during time shvatyivaniya a solution, in comparison with the mineral. In turn, at them smaller paropropuskaemost, that sometimes limits possibility of their application. Defect is smaller paropropuskaemost as a result of ageing under the influence of atmospheric factors and ultra-violet radiation.

For especially exacting clients ATLAS has entered on the market akrilovuyu plaster for colouring in weight. Thanks to it the investor can zaproektirovat the, unique and unique colour of plaster. Akrilovyie decorative front plasters ATLAS FOR COLOURING In WEIGHT are made in the form of white (for light colours) or sulphur (for more dark colours) weights which before the use needs to be painted. Akrilovaya pitch on which basis plaster is made, allows – without harm for durability – to paint plaster in the necessary colour. For colouring use the standard pigmentary pastes admitted to application in building.

SILICATE PLASTERS

The basic substance in silicate plasters is liquid glass. These decorative front plasters with success are made already over hundred years. They have kleyuschimi, knitting and impregnating properties. As initial substance quartz sand SiO2, alkaline carbonic kaliy and gidrookis kaliya (KOH) serves. All these components in the course of fusion at the temperatures exceeding 1400 0C form liquid glass – substance for silicate plasters. Thanks to applied substance silicate plasters well pass steam and proof to microbiological corrosion. They perfectly approach for industrial regions as, entering reaction with carbon dioxide, harden definitely.

The important factor in the course of facade pollution is the plaster pliability to electrostatic pressure. If in it organic substances contain many, it is faster elektrizuetsya and in this connection becomes soiled more fast. From here follows, that the facades plastered by mineral or silicate plaster, become soiled less. Considering process shvatyivaniya and plaster drying, the especial attention needs to be paid on changed atmospheric conditions during fulfilment of works. In this connection applying silicate and mineral decorative front plasters it is very important to protect a facade not only during fulfilment of works, but also during time shvatyivaniya. Plasters on the basis of mineral substances (mineral and silicate plasters) are characterised by higher water absorptivity, however, they also give a moisture outside thanks to what dry up more fast much more fast. Now progress is in colouring of silicate plasters at such level, that despite many restrictions (for example, high schelochnost plasters), there was a possibility to make plaster in wide colour scale. GROUP ATLAS has expanded recently the range, there were silicate decorative front plasters ATLAS SILKAT. It is made in 355 colours. It is accessible in two invoices: rough – thickness of grain to 1,5 mm (designation N-150) and to 2 mm (N-200), and also rustikalnaya – thickness of grain to 2 mm (designation R-200). Before oshtukaturivaniem it is necessary to put lining plaster weight ATLAS SILKAT ASX which it is in regular intervals allocated on all basis by means of a brush or the painting platen.

SILIKONOVYIE PLASTERS

The problem of restoration of facades is not limited only to giving of an aesthetic kind by it for short time. It is necessary to pay attention that plasters give in to pollution. Definition of level of firmness pokryivochnogo a layer to pollution very much a difficult task. After realisation of some researches it is confirmed, that decisive influence on firmness pokryivochnogo a layer to pollution has a corner of humidifying of a material from which the definitive layer is executed. The above it is, the the layer will be more waterproof, that does not allow pollution to get into the basis.

Practically, on a surface of a facade we can observe, so-called, effect of partial self-cleaning of a facade. It is possible thanks to application in plasters, in the form of the substance, modified silikonovyih pitches. Thus, receive silikonovyie decorative front plasters - the newest generation of the plaster mixes ready to use. Their success consists in a successful combination of excellent properties of covers of mineral plasters with the modified synthetic pitches.

As we already recollected earlier, binding substance in silikonovyih plasters is silikonovaya pitch, in insignificant degree modified akrilovyim substance which does not incur a sealant role as akrilovaya pitch (akrilovyie decorative front plasters), it improves moving of water steam, limits water absorptivity and thanks to the structure and absence of formation on its surface of electrostatic pressure, improves removal of all pollution under the influence of an atmospheric precipitation (effect of self-cleaning). Silikonovyie decorative front plasters are characterised by the big firmness to many chemical factors (exhaust gases, ozone, acid rains, ammoniac evaporations, sulphur and phosphorus oxides).

From here it is visible, that they can be used with success in the polluted industrial regions. These plasters more dense, than mineral. They are characterised bolshey by elasticity and adhesion, especially to the smooth bases. Silikonovyie pitches more proof to heats, than the majority of similar synthetic pitches. In connection with possibility of application both organic, and inorganic pigments it is possible to receive very wide colour palette of plasters. In trading range of firm ATLAS silikonovyie plasters ATLAS SILKAT N and R are offered almost in 600 colours!.

Durability of colour in plasters is reached by strong shvatyivaniya a pigment by an inorganic part silikonovoy pitches, and the organic part of substance is responsible for the reduced humidifying of plaster. Silikonovyie decorative front plasters are accessible in two invoices: rough, thickness of grain to 1,5 mm (designation N-150) and to 2 mm (N-200), and also rustikalnoy, thickness of grain to 2 mm (designation R-200). Before drawing silikonovoy plasters apply means ATLAS SILKON ANX. It is ready plaster lining weight which thanks to the contents of a small crumb, improves adhesion of the basis, and also limits occurrence on a surface of plaster of the stains caused by properties of the basis or its inappropriate preparation. All above-stated decorative front plasters are accessible in the colour range corresponding new, to considerably expanded colour palette of paints of firm ATLAS.

Taking in attention all above-stated facts, difficultly unequivocally to tell, what plaster the best and what should be used for facade furnish. All depends on the accepted criterion of comparison. If for criterion of comparison the price or paropronitsaemost starts, the best decision for a choice will be mineral or silicate shtukaturka.-Akrilovye, silicate and silikonovyie decorative front plasters get advantage when more important koloristika or simplicity of fulfilment.
