    Ways and features of drawing

    Experts identify two methods of applying the composition: manual and machine. It is necessary to adhere to the main provisions. The maximum indicator of the thickness of the plaster is 2 centimeters, while the average value is 5 millimeters. Density varies from about 600 to 1200 kg / m ^ 3. Other finishing materials are applied only after the coating has completely dried.

    The time spent on drying may vary. It depends on the indoor climate (humidity and temperature).

    Myths and delusions. Terms of use

    Since the product first appeared on the market, it immediately attracted the attention of buyers.As a result, many opinions and myths about the product appeared.

    Negative reviews about the material formed as a result of numerous violations in the process of application. To save money, many carry out their own styling, without the necessary experience and tools. Due to irregularities, the positive characteristics of the composition decrease significantly.

    Be careful when applying a decorative layer over plaster. This material can clog its pores, while depriving acoustic protection. For work, choose the special "breathing" compounds that are recommended for use with special plaster.

    What you need to know before starting work?

    Acoustic plaster is ideal for use in rooms with different dimensions. It is recommended to use for the design of compact apartments. Additional finishing practically will not occupy free space. If the size of the room allows, for greater efficiency, you can join several layers. This technique will help to significantly increase the level of protection of the room from the sounds - the noise is extinguished in contact with the porous texture of plaster.

    If you decide to carry out the installation procedure yourself, be sure to read the instructions for the composition. For rooms with high humidity, experts recommend the use of cement formulations. Gypsum-based plaster is ideal for rooms with dry air.

    Wall preparation

    Before applying acoustic plaster, you must first remove from the wall the old finish. It should rid the walls of exfoliating materials that may fall off during the operation of the new composition. It is also necessary to eliminate traces of rust and grease stains. Large defects, such as potholes, chips and cracks, are overlapped with cement mortar.

    To enhance the noise absorption function, metal mesh is mounted along with the plaster. The cell size is 10x10 millimeters. The material will set better if you hold the primer in two layers.

    Making a solution

    It is advisable to prepare the solution at an air humidity that does not exceed 75%. Optimum temperature conditions range from 16 to 26 degrees above zero Celsius. You must first prepare a large container of about 30 liters.There should be filled with dry plaster. It is in this form that the product is sold in a store.

    In the process of breeding rely on the instructions to the product. All necessary information should be indicated on the package, such as dilution proportions, volumes, consumption. To dilute the dry mixture, use water at room temperature.

    The mixture must be thoroughly mixed until a homogeneous mass is formed. A construction mixer is perfect. Experts recommend mixing the composition several times. The finished composition has a uniform structure without lumps.

    Finished plaster must be applied to the wall within four hours. After it begins to harden. Reuse of the composition is not possible, so watch the time carefully.

    Drawing

    As soon as the wall is prepared and the mortar is diluted, it is time to apply the material to the surface. First, create a thin layer - grout. At the end of the day should be applied to the control layer. The composition is distributed on the wall evenly.

    As we noted in the article, the thickness of the layer may be different. The higher this figure, the more effective sound-absorbing properties.

    Do not overdo it with thickness.

    If you apply a too thick layer of plaster on the wall, then in the process of drying it will crack. Rules are used to level the surface. Excess material is removed using a half-liner. For the subsequent finishing it is recommended to use water-based paint or plaster of a decorative type.

    What to look for when choosing?

    At the time of purchase, the main thing is to calculate the amount of material needed. Make it easy. Each package indicates the consumption of funds per square meter of surface. Knowing the exact dimensions, it is necessary to calculate the amount is not difficult. Experts recommend to buy plaster with a margin.

    Depending on the composition of the plaster, it is used under various conditions, whether it is high humidity, heat or extreme cold.

    A quality product - a guarantee of durability, reliability and environmental friendliness. Purchase only certified products from official manufacturers.

    The choice is available both domestic and foreign plaster. If you purchase goods in stationary stores, check the packaging for integrity.
