Has construction or renovation finished? All that remains is a small matter: the design of the facade and surfaces in the house. The most popular material is decorative plaster for interior wall decoration. This is a modern product that has long ceased to be used only indoors. Today, universal decorative plaster is suitable for both interior and facade work. Just imagine how convenient it is.

Features and classification

Our website presents decorative plaster for walls (for external and internal use) in a large assortment. A detailed description, clear photos and price are the main parameters that allow you to independently decide on a purchase. However, the wide variety of materials sometimes causes some difficulties. Let's try to understand this diversity and understand which plaster mixtures are best suited for interior work.

First of all, we note that all building materials are divided into:

  • dry, requiring preliminary preparation;
  • ready to eat.

The second option is much more practical and convenient to use, although its cost is slightly higher. Thus, when you need decorative plaster for interior wall decoration, you need to decide: do you want cheaper or better?


The next important criteria are the base and composition of the plaster mixture. Today there are the following varieties:

  • mineral. This is a class based on lime-sand and cement compositions. Gypsum plaster mixtures are the most environmentally friendly, but are characterized by less resistance to wear compared to other types;
  • acrylic. They are characterized by high plasticity and resistance to high humidity and extreme temperatures. Polymer mixtures are suitable for bathrooms and other rooms;
  • silicone – universal coatings based on polymer resins. They are highly wear-resistant and durable. Silicone plaster is excellent for interior work. It hides any old coating. Thanks to its self-cleaning effect and high ultraviolet resistance, this is the best facade plaster mixture. Easy to use, does not require significant effort for application or further care. The only drawback is the price;
  • silicate - similar in name to the previous ones, but significantly different in characteristics. They are based on liquid glass, which increases the resistance of the material to microorganisms (fungi, mold, etc.) and moisture. They are often used indoors because they are highly fire resistant. In addition, silicate decorative plaster for interior wall decoration is a recognized leader among coatings in terms of service life. The only “but” that can stop a buyer is the price. Although it more than pays for itself after more than 50 years of use.


Dry plaster mixtures (for example, sand gypsum) are most often used to finish the ceiling and walls in the corridor inside the house, and synthetic ones based on polymers and resins are often used for building facades.

Decorative effects


To decide on the finishing material, you need to pay attention not only to the composition, but also to the appearance of the resulting coating. For interior finishing, for example, in a corridor, various plaster compositions are used, which differ in decorative properties.


Let's look at the most popular ones in more detail:

  1. Structural is a ready-made adhesive mixture containing large particles. When decorating walls, marks are formed on the surface, reminiscent of tree bark damaged by insects. They call it “Bark Beetle”. Most often these are external plaster mixtures.
  2. Textured - plaster that imitates the surfaces of natural materials. They are very popular among designers because they allow you to create an original interior. These materials are distinguished not only by their exclusive decorative qualities, but also by their environmental safety and fire resistance. They can be applied to any surface without preliminary work, as they flawlessly hide all the imperfections of the walls.
  3. Flock or silk - consists of natural components (cellulose, silk fiber, mineral dyes, etc.). Plaster allows you to create a surface that is not only unique in appearance, but also practical.
  4. Marble chips are one of the most popular coatings. Granite or other particles of natural materials are added to it, which differ not only in color, but also in size. The resulting coating is characterized by high resistance to environmental factors: temperature changes, precipitation, sunlight, etc.
  5. Venetian plaster is the undisputed leader among finishing materials. It not only elegantly decorates any room, but also has impeccable performance characteristics.

These are the most popular varieties. But if they are difficult to understand, then we suggest contacting the consultants of our virtual representative office. They will provide comprehensive information regarding the material and the specifics of cooperation, and will help calculate the consumption of the plaster mixture.

There is a certain stereotype about performing plastering work, as if the work necessarily involves making a solution of cement, sand and water, which is applied to the wall with a trowel or other tools. Accordingly, when it comes to dry plaster, an association arises with a mixture of bulk building materials.

However, dry plaster for interior work is a well-known plasterboard wall decoration to many, which is the subject of this article.

General information

So, we figured out what dry plastering is. Naturally, it contains gypsum, which accounts for 93 percent of the total material. There is cardboard or paper on both sides of the gypsum layer, so the material does not crumble or crumble. In addition, dry gypsum plaster includes starch and organic substances, which improves its properties.

The main advantage of drywall is its versatility, as it is perfectly suitable for subsequent different coatings. Most often, decorative plaster, wallpaper, tiles, etc. are used for these purposes.

In addition, dry plaster has other advantages, among which are:

  • The material is environmentally friendly, as it does not contain harmful substances, including the release of toxic elements during combustion.
  • Flame resistant.
  • Excellent sound insulation qualities, since the gypsum layer has an increased density, due to which it dampens sound waves.
  • Wall finishing is much faster and easier than with traditional plastering.
  • Low cost of finishing, especially considering that with traditional plastering with high-quality mixtures, the consumption of dry plaster per 1 m2 is 8-10 kg with a coating thickness of about 10 mm.

Advice!
An excellent finishing option is decorative bark beetle plaster, which can look harmonious in almost any interior.

Of course, this also has some disadvantages:

  • The material is not strong enough, as a result of which furniture and household appliances cannot be attached to dry plaster.
  • Even moisture-resistant panels will not be able to withstand exposure to water. Therefore, in the event of flooding from above, the apartment will have to be renovated.

Installation of dry plaster

There are two main types of installation of dry plaster:

  • Gluing with special glue.
  • Frame mounting.

Now let's look at the features.

Glue installation

This method involves attaching drywall to a special glue, for example, Knauf-Perlix or some other - the price for them is approximately the same. The composition is diluted with water in the proportion indicated on the packaging, as a result the mixture should be quite thick, homogeneous and sticky, so that it is convenient to apply it to the walls.

Advice!
Construction boards for dry plaster are quite large in size, so it is unlikely that you will be able to complete the installation alone. It is advisable to call one or two assistants for help.

The instructions for installing drywall by gluing are quite simple:

  • The walls are first cleaned of dirt and dust.
  • Then a primer is applied to the surface, which will improve the adhesion of the adhesive solution to the wall surface.
  • After the wall has dried, rows of cakes are applied around the perimeter and in the center, which should be located at a distance of 30 cm. Or the glue should be applied directly to the panel.
  • Then the sheet is leaned against the wall and leveled using a building level.

The main advantage of this installation is the simplicity of the process, thanks to which you can finish the walls with your own hands, even without having experience working with drywall.

Frame mounting

This technology is radically different from the method described above, since it does not require wet and dirty processes. Drywall sheets are fixed to the metal profile using self-tapping screws.

The work is performed in the following order:

  • First of all, a starting profile is screwed to the floor, which should be located along the wall.
  • Then you need to install the profile on the ceiling so that it is located in the same vertical plane as the starting rail. To do this, you need to insert a vertical stand into one of its edges, not reaching the ceiling 1-2 cm, and apply a level. When the stand is in a vertical position, a mark should be placed on the ceiling.
    Then the procedure must be repeated from the other edge of the rail and connect the marks with a straight line, along which the upper profile is installed.
  • Next, vertical posts are attached to the lower and upper profiles. For intermediate fixation between the floor and ceiling, U-shaped brackets should be used, which must be installed every 60 cm. In this case, the position of the racks must be checked with a building level.
  • After installing the frame, you should install drywall on it. As mentioned above, self-tapping screws are used for this.

Note!
After dry plastering, you need to cut off the edges at the joints between the sheets, then stick a special mesh on them and seal them with putty.
After this, the walls are completely puttied.

In order for the repair to be truly high-quality and last for many years, when performing dry plaster, you must follow the basic rules listed below:

  • Dry plastering should not be carried out in rooms with high humidity or at temperatures exceeding 45 degrees Celsius, as this will cause delamination and deformation of the sheet.
  • In winter, work can be performed at temperatures not lower than 4 degrees.
  • During the installation process, it is necessary to ensure that the panels are installed evenly. However, you should not use excessive physical force to align the sheets, as they can easily crack.
  • In rooms where there is high humidity, it is necessary to use moisture-resistant plasterboard.
  • If an increased fire hazard of the room is expected, then the finishing should be done with fireproof plasterboard.
  • Before installing drywall sheets, it is necessary to lay all communications in the wall. If the installation is carried out on a frame, then the wiring can be laid in the resulting cavity between the wall and the panels.

Conclusion

Using dry plaster is an excellent alternative to traditional wall plastering. Of course, this finishing option cannot completely replace it; for example, dry plaster is not applicable for exterior work. But, in some cases, leveling walls with plasterboard is a much better option.

For more information on this topic, watch the video in this article.

Dry plaster on the modern market of construction and finishing materials is represented by several types.

Types of dry plaster

Blends:

  • dry mix for cement-based plaster (cement-lime plaster, cement-sand plaster);
  • gypsum plaster mixtures.

Dry sheet plaster:

  • gypsum sheets (lined on both sides with soft cardboard);
  • wood fiber sheets (crushed wood is pressed, waterproof and other impregnations that strengthen the material are added);
  • gypsum fiber sheets (88-90% consist of gypsum, the other 12-10% are made of paper fiber).

You can also select plaster for interior and exterior use, finishing coating and plaster for leveling the surface of walls.

Area of ​​application of dry plaster

Cement plasters are more often used as a material for facade and any other exterior work. These are strong plasters that form a moisture-resistant coating tightly adhered to the base of the walls. You can use plasters with a cement base in bathrooms and toilets.

Cement-lime mixtures can be used on concrete, aerated concrete, brick, ceramic surfaces, as well as cement plasters.

VOLMA-Aqualayer (light machine-applied plaster, resistant to fungus formation), OSNOVIT Startwell T-21 (for use on concrete and brick in rooms of any humidity level), KREISEL Putzmortel 560.

Dry plaster for interior work based on a cement-sand mixture has increased moisture resistance, ductility, frost resistance and increased mortar adhesion.

Manufacturers and brands of dry mix: KNAUF Grünband (cement-sand, water-repellent plaster with thermal insulation properties), KNAUF Unterputz facade plaster, KNAUF Sockelputz base plaster.

Gypsum plasters can be used to prepare walls for wallpapering, painting, laying ceramic tiles; they fit well on ceilings, bases made of concrete, brick, and fiberglass.

Manufacturers and brands of dry mix: KNAUF Rotband (universal gypsum plaster), KNAUF MP75 (machine applied), VOLMA-Layer Universal, VOLMA-Layer MN (machine applied).

Sheet plaster.

Construction boards for dry plastering walls are popularly known as “gypsum plasterboard” (GKL). This finishing building material can be used both for finishing premises and for constructing load-bearing walls and partitions with dry or normal humidity conditions. Can also be used for the manufacture of decorative structures.

Manufacturers: VOLMA GKL, KNAUF GKL, KNAUF GKLV (moisture-resistant plasterboard sheet), KNAUF GKLO (fire-resistant GKL), KNAUF-Acoustics (sound-absorbing sheets).

Wood fiber sheets, hardboard or simply fiberboard can be used as a construction and repair and finishing material for sound and heat insulation, leveling walls, erecting wall partitions and roofing.

Gypsum fiber sheets (GVL), unlike plasterboard, are a homogeneous material without a shell. This material is denser and stronger than drywall. Suitable for organizing walls, ceilings, floors. Can be used in rooms with a high level of fire safety.

Above we listed materials, most of which cannot be used as a finishing coating (unless the surface is used for wall painting or painting on dry plaster). Speaking about dry plaster, one cannot fail to mention the decorative component.

So, dry decorative plaster can also be used as an external (facade) coating, and as a material for finishing interior spaces.

Manufacturers and brands of decorative plaster: The most popular among dry decorative plasters are plasters such as “bark beetle”, “fur coat” and “lamb”, presented in the catalogs of most specialized manufacturing companies (like KNAUF or Ceresit). The texture of the coating is achieved through the use of grains of different fractions (size from 0.5 to 4.5 mm) in the mixture.

In addition to its decorative functions, this type of plaster perfectly protects walls from moisture and climate change, the influence of ultraviolet radiation and excess heat loss.

Consumption of dry mixture for plaster

On the packaging of the dry mixture, all manufacturers, without exception, write the approximate consumption of material per 1 m². However, this is not the consumption of dry material - it is the consumption of finished plaster. To determine the consumption of the dry mixture, it is necessary to subtract the consumption of water used to prepare this amount of finishing material from the total cost of the finished plaster.

Dry plaster: price

Depending on the type of plaster, the cost of the material is:

  • Ceresit CT 24 (cement mixture for plastering) - $7/25 kg (ready mixture consumption 1.2 kg/m²;
