Plaster "Bark beetle" is known even to those craftsmen who are far from the issues of finishing walls and facades. With this material, you can form a characteristic surface that will resemble wood affected by a bark beetle. However, this feature is not the only one. The described mixture belongs to textured plasters and is made on the basis of a polymer or mineral binder.
Before going to the store, you need to calculate the amount of material that will be needed, for this you need to know the consumption of bark beetle plaster per 1m2. However, in order to determine the required amount of material, additional factors should be taken into account, among them should be highlighted:
- thickness of final layer;
- properties of dry mixes;
- workable area.
This list allows us to conclude that before buying a material, you should determine the consumption per square meter, and then find out the product of the volume and area of the surface to be treated.
Expense calculation method
Even a specialist needs to know what is the consumption of bark beetle plaster per 1m2. 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 from 2.4 to 4 kg. This parameter depends on the final layer thickness and filler particle fraction.
The exact amount of solution is difficult to determine. For reference, information is taken that is given by the manufacturer. When buying a solution, it is necessary to add about 10% of the stock to the calculated volume. There is another dependence, which is expressed in the consumption of plaster from the manufacturer. Even if there is a slight discrepancy in the amount of the mixture, for large volumes this value can be significant.
For example, with a 10 mm layer thickness per square meter, you will spend about 6.5 kg of composition from the Volma manufacturer. The difference in flow rate may arise from the volume of water that is added to the solution. As for the decorative plaster "Prospectors", its consumption per square meter is 9 kg. When finishing a room of a small area, which is equal to 30 m2, the difference in the mass of the dry mixture will be 270 kg. In this example, a layer with a thickness of 30 mm is considered.
Volume calculation method
If you need to know the consumption of bark beetle plaster per 1m2, then you need to familiarize yourself with the calculation method. This takes into account the factors affecting the finalmeaning. Among the most important are the curvature of the walls and the type of mortar. However, one of the most significant is the layer thickness. For the correct calculation, beacons should be installed, for this a level is used. This approach will allow measurements even on a curved surface.
After all the measurements are taken, add them up 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. It can be imagined that 10 m2 of the area is to be processed. The walls are littered by 5 cm. Beacons are installed in 3 places. The deviation will lie in the range from 2.4 to 6 cm. These numbers are added up, and the result is divided by three. This will give you 4, which will be the thickness of the layer that you will apply to the walls.
When the thickness is known, you can start calculating the flow. It is better to use the data on the package for this. As an example, consider the Knauf Rotband plaster. For one square meter of a layer 10 mm thick, it is necessary to spend 8.5 kg of the mixture. If you have basic indicators, you can determine the consumption per square meter with a thickness of 4 cm.
To work, you need 34 kg. However, the area of \u200b\u200bthe room is larger, so the figure must be multiplied by 10, which will allow you to get 340 kg. It is also important to remember the need for a margin of 10%. As a result, it will be possible to obtain a figure equal to 374 kg. Relative to the number of bags that you will spend to process one square meter, this figure will beequal to 10. "Knauf Rotband" is usually sold in 30 kg. About 13 bags will be needed for high-quality plastering of the surface.
Conclusions on volume calculations
If you need to determine the consumption of bark beetle plaster per 1m2, then you should use the algorithm presented above, focusing on the indicators in the instructions. It is important to take into account also 10% of the stock. With the cost of the mixture, the fraction of granules plays a huge role. The smaller they are, the more economical the powder will be spent. Such solutions are usually used for interior work.
Applying technology
Ceresit bark beetle plaster is quite popular among consumers. Consumption per 1 m2 of this mixture will be 3.2 kg. Application is carried out in the traditional way. The surface of the walls is cleaned, freed from the old finish, dirt is removed from it. If the room is damp, then it is necessary to carry out antiseptic impregnation. If there are rusts or deep cracks on the base, they should be sealed with gypsum putty.
You can allow the presence of height differences within 1 mm per 1 m. If necessary, the walls are leveled. The surface is covered with a primer to prevent excessive absorption of moisture by the plaster. If the coating is processed from a lime-sand composition, then it is possible to refuse to apply a primer. Before applying the mixture, it is important to study the features of use. Consumption of bark beetle plaster per 1m2 to thismoment you should already have determined.
The mixture is applied to a grater or spatula, and then applied to the surface. The tool must be held in relation to the base at an angle of 60 °. The layer thickness should not be less than the grain size. You can determine this visually. If you saw grooves when leveling the layer, then this is the required thickness.
Forming a pattern
Consumption rates of bark beetle plaster per 1m2 are now known to you. But it is also necessary to take an interest in the technology for the formation of a particular pattern. Using a grater or trowel, the 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 strips. A chess structure can be formed by moving the hand crosswise.
You can get a frosty pattern with wavy and circular movements. When grouting the surface with a polystyrene foam trowel, you can get a “cork” if you move the tool around with a small amplitude. Within three days, the maximum plaster will dry. The time can be reduced to two days and will depend on the temperature. Indoors, drafts should be excluded. After 3 days, the surface can be covered with acrylic varnish or painted.
Applying errors
Before startingwork, be sure to study the application technology. The consumption of bark beetle plaster per 1m2 is not the last thing the master should know about. However, it is important to familiarize yourself with the nuances that will eliminate errors during application. They usually occur when the surface is not properly prepared.
"Bark beetle" has excellent adhesion, but the possibilities of this composition are not endless. For example, the application of plaster should not be allowed on the old coating. As the temperature drops and rises, different finishes will behave differently. Under such conditions, there is a possibility of cracking of the layer, and it is quite difficult to repair the coating.
About temperature norms and work breaks
With the help of a primer, you can increase the adhesion of materials, this step should not be neglected. Having studied the features of the bark beetle plaster, you can find out the consumption per 1m2. This was discussed above. However, it is important to take an interest in the temperature range that should be followed when applying the mixture. It varies from +5 to +30 °C.
The described composition is frost-resistant, but at the stage of drying it should be kept at a positive temperature. Applying a layer on one surface should be carried out without interruption. The plaster sets quickly, and the final pattern will depend on the movements. If you increase the breaks, then the picture will be divided into separate fragments, this version of it looks sloppy.
Mix ratio
If you plasterpurchased in dry form, then it will need to be closed with water. To do this, prepare a container that is filled with water. You already know the consumption of bark beetle plaster per 1 m2, it is important to observe the proportions of the preparation of the composition. For every kilogram of powder, add 200 ml of liquid. The temperature of the latter should be equal to the limit from +15 to +20 °C.
Conclusion
Plaster "Bark beetle" consists of a binder and grain. The first ingredient provides for the presence of cement with the addition of polymers and polymer resins. As for the grain, it is it that allows you to get grooves when applying the mixture. Before you go to the store, it is important to ask what is the consumption of decorative bark beetle plaster per 1m2. About 10% of the margin should be added to this value so as not to be faced with the need to interrupt work, because this will negatively affect the appearance of the finish.
