"Bark beetle" (plaster) - consumption per 1m2: application technology
Plaster "Coroed" is known even to those masters,which are far from the issues of finishing the walls and facades. With the help of this material, it is possible to form a characteristic surface that will resemble wood damaged by a bark beetle. However, this feature is not unique. The described mixture refers to the textured plasters and is made on the basis of a polymer or mineral binder.
Before going to the store you need to calculatethe amount of material that will be needed, for this you need to know the cost of plastering "Coroed" on 1m2. However, in order to determine the required volume of material, additional factors should be considered, among them:
- thickness of the final layer;
- properties of dry mixtures;
- treated area.
This list allows you to conclude that before you buy the material you should determine the flow per square meter, and after you find out the product of the volume and area of the surface to be treated.
Method of calculation of flow
Even a specialist needs to know what the expense isplastering "Bark beetle" on 1м2. The calculation method differs from that used in the case of cement-sand or gypsum plasters. For "Bark beetle" there is a norm per square meter, which is equal to the limit of 2.4 to 4 kg. This parameter depends on the total thickness of the layer and the fraction of the filler particles.
The exact amount of solution is determined fairlycomplicated. For reference, the information given by the manufacturer is taken. When buying a solution, you need to add about 10% of the stock to the estimated volume. There is another dependence, which is expressed in the consumption of plaster from the manufacturer. Even if there is a small discrepancy in the amount of the mixture, this value may be significant for large volumes.
For example, at 10 mm layer thickness per onesquare meter you will spend about 6.5 kg of the composition of the manufacturer "Volma". The difference in consumption can arise from the volume of water that is added to the solution. As for the decorative plaster "Starateli", its consumption per square meter is 9 kg. At the finish of the room a small area, which is 30 m2, the difference in the mass of the dry mixture is 270 kg. In this example, a layer 30 mm thick is considered.
Method of calculation of volume
If you need to know the cost of plastering"Bark beetle" for 1m2, then you need to learn the methodology of calculation. This takes into account factors that affect the final value. Among the most important - the curvature of the walls and the type of building mixture. However, one of the most significant is the thickness of the layer. For the correct calculation, you should set the beacons, this is done using the level. This approach will allow measurements even on a curved surface.
After all the measurements have been carried out,it is necessary to add them and divide by the number of points. This indicator will be the main one in determining the thickness. In order to better understand this issue, it is necessary to consider a specific example. You can imagine that you have to process 10 m2area. The walls are 5 cm thick. Beacons are installed in 3 places. The deviation will lie between 2.4 and 6 cm. These numbers add up, and the result is divided into three. This will get 4, this is the thickness of the layer that you will apply to the walls.
When the thickness is known, it is possible to proceedcalculation of consumption. It is better to use the data on the package for this. As an example, plaster "Knauf Rothband" can be considered. For one square meter of a layer 10 mm thick, 8.5 kg of the mixture must be used. In the presence of basic indicators, you can determine the flow per square meter at a thickness of 4 cm.
For work you need 34 kg. However, the area of the room is larger, so the figure needs to be multiplied by 10, which will allow you to get 340 kg. It is also important to remember the need for a stock of 10%. As a result, it will be possible to obtain a figure equal to 374 kg. Regarding the number of bags you spend for processing one square meter, this figure will be 10. "Knauf Rothband" is usually sold at 30 kg. For quality plastering of the surface, about 13 bags will be needed.
Conclusions on volume calculations
If you need to determine the consumption of plaster"Bark beetle" for 1m2, then we should use the algorithm presented above, focusing on the indicators in the instruction. It is important to take into account also 10% of the stock. When the mixture is used, the granule fraction plays an important role. The smaller they are, the more economical the powder will be consumed. Such solutions are usually used for internal work.
Quite popular among consumersplaster-bark beetle "Ceresite". The consumption per 1 m2 of this mixture will be 3.2 kg. Application is carried out in a traditional way. The surface of the walls is cleaned, freed from the old finish, dirt is removed from it. If the premise is damp, then it is necessary to carry out antiseptic impregnation. If there are on the base of rusts or deep cracks, they should be sealed with plaster filler.
You can assume the presence of elevations in1 mm per 1 m. If necessary, the walls are leveled. The surface is covered with a primer to prevent excessive absorption of moisture by plaster. If the coating is processed from a lime-sand composition, then the primer can be discarded. Before applying the mixture, it is important to study the features of use. The consumption of plastering "Bark beetle" by 1m2 by this time you should already be determined.
The mixture is applied to a grater or spatula, and afteris applied to the surface. The tool must be held in relation to the base at an angle of 60 °. The thickness of the layer should not be less than the grain size. This you can determine visually. If you saw grooves when aligning the layer, then this is the required thickness.
Forming a Pattern
The norms of the consumption of plastering "Bark beetle" for 1 m2 to youare now known. But it is necessary to take an interest also in the technology of forming this or that pattern. Using plaster or poluterk plaster must be leveled. The nature of the pattern will depend on the movements. With vertical movements, you can form a surface called rain. When the movements of the tool are horizontal, this will allow you to get the strips. The chess structure can be formed by moving the hand crosswise.
Frosty pattern you can get undulatingand in circular motions. When trowelling the surface with a polystyrene trowel, you can get a "cork" if you move the tool around with a small amplitude. Within three days, the maximum plaster will dry. Time can be reduced to two days and will depend on temperature. Inside the room, drafts should be eliminated. After 3 days, the surface can be covered with acrylic lacquer or painted.
Errors of application
Before you start work, be sure toshould study the technology of application. The consumption of plastering "Bark beetle" for 1m2 is not the last thing the master should know about. However, it is important to get acquainted with the nuances that will make it possible to exclude mistakes during the application. They usually occur when the surface is improperly prepared.
"Bark beetle" has excellent adhesion, howeverthe possibilities of this composition are not infinite. For example, the application of plaster should not be allowed on the old coating. With a decrease and increase in temperature, different finishes will behave differently. Under such conditions, there is a chance of cracking the layer, and repairing the coating is rather difficult.
About temperature norms and work breaks
Using a primer, you can increase the adhesionmaterials, this step should not be neglected. Having studied the features of plastering "Coroed", the consumption per 1 m2 you can find out. This was discussed above. However, it is important to ask also the temperature range, which should be adhered to when applying the mixture. It varies from +5 to +30 ° C.
The composition described is frost-resistant, howeverAt the drying stage it should be kept at a positive temperature. The application of a layer on one surface should be carried out without interruptions. The plaster quickly grasps, and the final pattern will depend on the movements. If you increase the breaks, then the picture will be broken into separate fragments, such variant looks sloppy.
If the plaster you have purchased in dry form, then itsit will be necessary to shut up with water. To do this, a container is prepared, which is filled with water. You already know the cost of plastering "Kroyed" on 1m2, the proportion of preparation of the composition is important to observe. For each kilogram of powder should be added 200 ml of liquid. The temperature of the latter should be equal to the limit of +15 to +20 ° C.
Plaster "Bark beetle" consists of an astringent and grain. The first ingredient provides the presence of cement with the addition of polymers and polymer resins. As for the grain, it is this that allows you to get grooves when applying the mixture. Before going to the store, it is important to ask what is the consumption of decorative plaster "Bark beetle" for 1m2. To this value should be added about 10% of the stock, so as not to encounter the need to interrupt work, because this will affect negatively the appearance of the finish.
