Decorative plaster is a mortar that is used to finish walls outside public buildings and homes, as well as inside offices, apartments and premises. The main purpose of the material is to increase the aesthetic and decorative qualities of the surface. Lately widespread acrylic plaster, in which a high molecular weight polymer acts as a binder, it provides excellent elasticity of the applied layer.
Structure
The acrylic resin of the same name plaster is a polymer, in addition to which inorganic and organic pigments can be added to the ingredients . Thanks to the latter, the composition acquires a color. The mixture contains mineral fillers, modifiers, as well as an aqueous dispersion of synthetic polymers. Modifiers are designed to improve the quality characteristics of the composition.
Varieties and their description
Acrylic plaster can be textured, it has a coarsely dispersed, highly viscous structure, in which mica, linen fibers, and also small pebbles act as a filler. Such a composition is used for decorating concrete, brick, plastered and wooden surfaces. These mixes are excellent for interior and exterior wall decoration.
In the manufacturing process, special particles are added that are able to hide irregularities and large defects. That is why application can be done on surfaces that almost do not require preparation. It will be enough to clean, dry and remove peeling elements. After applying the adhesive composition or a special solution of the type of concrete contact.
Textured plaster reviews
Textured acrylic plaster, according to users, has high hardness and water-repellent characteristics. After application, an air-permeable coating forms, which can imitate natural stone, fabric, wood and genuine leather. If we consider decorative plasters, then the most popular, according to users, are textured, which differ in low cost. Such acrylic plaster can be tinted upon application or painted after drying. On average, 2 kilograms of a mixture will take per square meter. Before purchasing, you must remember that a larger filler contributes to a high consumption of the composition. Users are not advised to apply this plaster in the rain or in wet weather, as well as in the event that the temperature drops below +7 degrees. Home masters argue that the application of textured composition can be carried out without the use of highly specialized tools, among other things, there is no need to involve professionals in the work.
Subtypes of textured plaster
Textured acrylic based plaster is divided into several subspecies, among them: lamb, fur coat, and bark beetle. In the manufacture of the first type, stones of different fractions are added. After completion of the work, it will be possible to obtain a surface that will be characterized by uniform granularity and roughness. The plaster of the fur coat texture used allows you to create a wall that is made in the form of a small hairiness. Acrylic bark beetle plaster is a composite composition, which has a small stone filler among the ingredients. During application, the master receives a furrowed texture that resembles a surface corroded by bugs. As a feature of textured plaster, the relief appears immediately.
Structural plaster
These materials have a thin layer structure and are made on an acrylic basis. Elements of quartz or marble chips are used as a structure-forming substance. Outwardly, the composition looks heterogeneous and grainy, and is used to decorate facades and decorate walls indoors. If fine-grained elements are added to the ingredients, the wall will look almost smooth, but with medium-grained components, the surface will receive a peculiar relief after completion of work. Application can be made on chipboard, mineral surfaces and drywall, with which the described mixture has excellent adhesion.
Reviews of structural acrylic plaster
According to users, structural plaster forms a layer that is breathable as well as weather and moisture resistant. It is not permissible to add coloring pigments to the composition, and the application should be done with a trowel on a clean and dry surface, which is pre-treated with a deep penetration primer. According to home craftsmen, the average consumption per square meter is 3 kilograms. If you are interested in structural acrylic facade plaster, then it is recommended to apply it in dry weather, while the temperature should not drop below +7 degrees. When carrying out the work, it is permissible to use different methods and tools, namely: a spray gun, a roller or a flat spatula. Experienced builders claim that to get the effect of the waves, you should use coarse-grained plaster, which is applied in a circular motion. As practice shows, the created layer is resistant to mechanical damage, impact resistance and allows wet cleaning during operation.
Reviews of Venetian Plaster
Venetian acrylic plaster for interior work, according to users, is quite expensive material, but the effect justifies the price. Most often, such compositions are used in rooms whose interior is supposed to be decorated in a classic or antique style. Using appropriate application methods, a glossy or matte surface can be obtained. The mixture is intended for application exclusively indoors, while it can be tinted. The surface must first be cleaned, leveled and dried. Experts recommend reinforcing the wall, and then cover with putty and primer. Buyers claim that if technology is broken, cracks can form on the surface, which will be very difficult to get rid of. The mixture is perfect for small rooms, as the Venetian acrylic plaster allows you to achieve the effect of increasing space. Using this composition, you can get a base that simulates precious stones. This is ensured by coloring with special pigments.
Acrylic Venetian plaster is a multi-layer coating, which is carried out with the addition of hydrated lime and marble chips. The structure is quite homogeneous. The finished layer visually resembles a surface made of onyx or natural stone. In order to achieve a positive result during application, it is necessary to have special skills and knowledge. During the work, flexible rubber spatulas are used, with which you need to apply the composition with thin strokes in several layers.
Mosaic plaster
Acrylic mosaic plaster is intended to create a finishing layer for the arrangement of plaster facade systems . This mixture is a thin-layer composition with a texture, which is represented by multi-colored stone chips. Grain size can vary from 1.4 to 2 millimeters. The material is ready to use, resistant to contamination and easy to clean during use. It can be used for both external and internal work, available in 38 color compositions.
The layer shows the quality of resistance to abrasion and precipitation.
Application can be made to cement-sand and cement-lime plaster, as well as drywall, hard putty and particle boards. This plaster is a transparent polymer binder, which has rounded quartz or crushed marble chips. The pigment is a polymer composition, which gives the mixture different colors.
Application Method
To all of the above recommendations, it is worth adding that acrylic plaster, the composition of which was described in the article, can be applied by yourself. During operation, the ambient temperature should not go beyond +5 to +25 degrees. When conducting outdoor work, you should not start manipulating if there is a strong wind outside, and the humidity is above 70%. It must be remembered that the operational characteristics of the layer will depend on compliance with the application technology. The surface should be prepared if the use of heat-insulating material is not provided. When working with a block or brick wall, the seams between the products should be cleaned by going one centimeter deeper. You need to get rid of dirt. Expansion joints can be cut to increase the penetration depth of the composition. The plaster should not be excessively fluid, you should not apply a layer at a time, the thickness of which will exceed 2 centimeters. If there is a concrete surface, then in advance it is necessary to apply a layer of lime plaster, which will be between the acrylic composition and the final coating.
Conclusion
Grouting should be done in a circular motion, a few hours after application. It is necessary to begin this stage when the composition will have the desired viscosity, sufficient to maintain a given shape.
