What is dry plaster and features of working with the material. Choosing a plaster mixture for interior work Types of dry plaster

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 (consumption of the finished mixture 1.2 kg/m²;
HP Start KNAUF (gypsum plaster) - $3.5/25 kg (consumption 1.58 kg/m²);
TEPLON-Bark beetle (decorative, heat-protective plaster) - $15.9/25 kg (consumption 1.52 kg/m²);
VOLMA gypsum board sheets - $6.25 per sheet 9.5/1,200/2,500 mm;
fiberboard sheets - $4.5 per sheet 25/1 220/2 400 mm;
KNAUF GVL sheets - $33.5 per sheet 10/1,200/2,500 mm.

One of the most labor-intensive types finishing works, perhaps, is especially true if you carry out this work yourself, without resorting to outside help. It will be a pity for the money and effort spent if, after drying, the walls become covered with cracks or the material completely moves away from the surface, which happens very often if the master does not have the appropriate experience in construction work. But, of course, the type and quality that you will use to carry out the work also play an important role. Therefore, the choice of composition should be approached seriously, since the success of plastering the walls will also depend on this.

For reference

You can make good plaster yourself. To do this, you need to select the ingredients, sift the sand, mix everything in the required proportions and add water. But all this will take a lot of time, and the mixture may turn out to be of poor quality. Therefore, it is best to purchase a ready-made composition that already has the required amount of dry mixtures, requiring only the addition of liquid.

Features of choosing plaster for walls

You can choose a solution for plaster depending on the surface of the wall, the time allocated for the work, as well as the expected cost of the composition. In order not to make a mistake, you need to know what plasters are on sale today. If you need to improve the facade, you should choose cement-lime or cement plasters. Internal walls are best finished with cement-lime or cement mixtures, as well as gypsum compounds. Depending on the fillers, the plaster may have different quality characteristics. For example, cement contains a substance of the same name as a binder, and sand acts as a filler. Among the advantages of this solution are long pot life after preparation, a durable surface after drying, and low cost. One cannot fail to note the versatility, because such compositions are suitable for both interior and facade work.

Long pot life makes work easier because you can mix several bags at once using a concrete mixer and without fear of the solution setting before you have time to work it out. Such mixtures are very suitable for inexperienced craftsmen. And after drying, the surface becomes resistant to mechanical stress.

If you choose such a dry mixture for plastering walls, then you should be prepared for some disadvantages. Among them are poor adhesion to concrete and smooth surfaces, the inability to perform a large amount of work per day due to heavy physical activity, as well as the formation large quantity mud. The cement will harden for quite a long time, so the repair work will take a long time, and further finishing can only be resumed after 2 weeks. The work requires preliminary plastering of the walls. During drying, high humidity will remain in the room; water is needed to crystallize the particles, so during the drying process you need to spray the surface with water, which complicates the process. If there are wooden structures in the room, then high humidity can cause them to deform.

Since the solution will have to be thrown onto the wall, a fairly large part of it will fall on the floor, forming a lot of dirt, in addition, this can lead to overuse of the mixture. But this is not the only source of dust, since when mixing the solution, cement particles will rise into the air, entering the respiratory tract, and this is known to be harmful to health.

Cement-lime plaster

If you are thinking about the question of which plaster is better, then you can pay attention to cement-lime mixtures, which also consist of sand. The advantages are the ability to use the composition for interior and exterior work, as well as for rooms where conditions are characterized by high humidity. After being applied to the walls, the cement-lime composition gives them antibacterial properties, eliminating the development of fungus.

The composition is convenient to apply, as it has an elastic consistency and adheres well to the surface. But the plaster solution will dry for about 4 months, in addition, the mixture is demanding in terms of technology. If the surface preparation is not carried out correctly or the recommendations for drying are not followed, the wall will become covered with cracks and will turn out to be loose. Dust from lime plaster is no less harmful than from the composition described above. If the solution gets on the skin, it may cause irritation and ulcers.

Gypsum plaster

Gypsum has fillers in the form of mineral additives. The color of the composition can be gray, white or cream. It dries quickly, which allows you to reduce the time for finishing work. To prepare the walls, there is no need to putty them, the mixture is plastic, during work it does not slide off the surface, and it can be applied in two layers, which allows you to process about 40 m2 per day. Less dirt and dust will be formed; among other things, the composition is non-shrinking and does not develop cracks after drying.

Disadvantages of gypsum plaster

If you are faced with the question of which plaster is better, then perhaps you should think about whether to purchase a gypsum composition, since it has many disadvantages. Among them it is worth highlighting: low viability, instability to mechanical stress, as well as moisture. You will have to work out the prepared mixture within 40 minutes, which requires professionalism and special skills from the master. Gypsum compositions are not used for external work, as they are not resistant to atmospheric influences.

Adhesive plaster

The mixture for plastering walls can also be adhesive. It consists of polymer additives, sand, special fibers and cement. As a rule, this mixture is used for installing insulation, but it can also be used for plastering walls using mesh. Due to the high cost of adhesive plaster, its scope of application is very limited.

Making your own plaster

After studying the ratio of ingredients, you can prepare your own solution for leveling the walls. The proportions of lime plaster are as follows: 1 part 3 parts sand. The proportions can be slightly changed if the fat content of the lime is excessive or insignificant. Thus, for one part of lime you may need from 1 to 5 parts of sand. After combining the ingredients, the composition should be mixed, gradually adding liquid and sand.

Cement-sand plaster: preparation

Materials for plastering on a cement-sand basis are also combined in accordance with the proportion. To carry out the work you will need cement, sand, lime and water. First, part cement and 4 parts sand are mixed, then you can add 0.1 part lime. Liquid is gradually added to the solution until the mixture reaches the desired consistency. Depending on the brand of cement, the proportions may vary. If you want to prepare a mixture for plastering walls from M200 cement, then you should combine sand and cement in a ratio of 1 to 1. When using M500 cement, prepare sand in the amount of 5 parts and cement in the amount of 1 part.

Other criteria

If you still cannot find the optimal mixture for plastering the walls, then you should be guided by the materials they are based on. If you have a foam concrete surface that has a porous structure, it is best to purchase a gypsum mixture. You can also buy it, but it should be taken into account that foam concrete has good absorbency, and the plastered surface will require splashing of water. If you have to work with wooden walls, then cement- and lime-based plaster, which is applied over a shingled sheathing, is best suited for them. In terms of price, gypsum plasters are more expensive compared to cement plasters. However, if you take into account the consumption of gypsum plaster, cement plaster will cost much more. After all, if you apply the first option with a centimeter layer on square meter, then 10 kg will be consumed, while the cement composition will be consumed in the amount of 16 kg.

When choosing a mixture for plastering walls, you should not purchase it in large quantities. First you need to take two packages, and then try them out. If the setting time corresponds to the instructions, then you can purchase the required amount of the mixture. It is important to avoid improper storage of gypsum plaster, as in this case it will harden within 10 minutes after adding water. But if the required amount of cement is not added to the cement plaster, it will crawl along the wall during the application process.

Choosing the best plaster by manufacturer

As experts recommend, you should not purchase mixtures that are made by little-known manufacturers. The most popular products on the modern market are those supplied by the German company Knauf. It produces high-quality mixtures, and the price of these products is slightly higher compared to domestically produced goods. Among the latter, the companies “Starateli”, “Osnovit”, “Yunis”, “Volma” and “Kreps” have established themselves. The quality of “Prospectors” is not inferior to Knauf. But if you purchase a large batch, the difference per package of 30 kg can become noticeable.

Characteristics of gypsum plaster brand "Knauf Rotband"

If you decide to use the Knauf Rotband mixture for leveling the walls, you should familiarize yourself with its characteristics. It is intended for high-quality plastering of walls and ceilings that have a solid base. This includes brick and polystyrene foam surfaces. Smooth concrete surfaces are especially easy to process. This composition can be used for finishing rooms with normal humidity and in bathrooms and kitchens.

Gypsum plaster “Knauf Rotband” (30 kg) is applied in a layer, the thickness of which can vary from 5 to 50 mm. With a 10mm layer you will need 8.5kg per square meter. When kneading, it will take approximately 20 liters of water per 30 kg bag. The surface will dry within 7 days, but the finished solution must be used within 25 minutes. Compressive strength will exceed 2.5 MPa, while flexural strength will exceed 1.0 MPa. Gypsum plaster "Knauf Rotband" (30 kg) is a universal mixture that provides increased adhesion to almost all materials. Packaging of the above volume will cost the consumer 370 rubles. If you have to work with highly absorbent surfaces, then a primer is first applied to them.

Characteristics of gypsum plaster “Volma-layer”

Volma plaster, the price of which is 280 rubles, does not require preliminary puttying and can be applied manually. Approximately 9 kg of dry composition will be needed per square meter with a layer thickness of 10 mm. This layer will dry within 24 hours, and brick, gypsum or cement plaster, concrete or aerated block can be used as a rough surface. After preparation, it is necessary to develop the solution within 45 minutes. Volma plaster, the price of which is quite reasonable, is not used for facade work. It can be applied in a layer of 5 to 60 mm.

Today on the market there are many materials intended for finishing walls. Among finishing materials, decorative dry plaster occupies a special place due to the uniqueness and uniqueness of the surface created. The variety of textures, colors, and application methods allows you to bring any design solution to life.

The main advantages of its use in the interior:

1.	Versatility.	Decorative plaster can be used for both internal and external walls (see Decorative facade plaster: choosing the right one) with almost any base - concrete, brick, plasterboard.
2.	Can be used for all shapes and surfaces.	Plaster can be used on any shape - flat, convex, concave, and the coating is seamless.
3.	Exclusivity of the created texture.	Each application is unique, even two rooms made by the same master using the same technique will have their own characteristics.
4.	Durability.	Decorative plaster is one of the most ancient finishing materials. It was used in ancient Egypt and has survived to this day.
5.	Strength.	Decorative plaster coatings are significantly stronger than other finishing materials and can withstand significant mechanical stress.
6.	Abrasion resistance.	Plaster is practically not inferior to artificial stone and allows repeated wet cleaning, which allows it to be maintained in its original condition for many years.
7.	Exceptional tactile properties.	The coating is incredibly pleasant to the touch; various textures create a relief similar to natural materials.
8.	Environmental friendliness.	The coating is environmentally friendly, and protective waxes are made from natural materials.
9.	Ease of preparation.	Decorative dry plaster can be prepared (mixed with water) in the quantity required for use.

Among the disadvantages, several technological features of applying the material can be identified:

Decorative dry mix plaster or ready-to-use paste is applied using “wet” technology, the process is quite lengthy and requires drying of each layer.
Continuity, the coating is applied to the entire wall in one go to eliminate the formation of visible joints.
Difficult to remove (see How to remove old plaster from walls without problems). If you need to replace the coating, the plaster will have to be knocked down, which is quite labor-intensive.

Types of plaster

Dry decorative plaster is produced:

Based on gypsum.
Cement based.
Acrylic (see Acrylic plaster for facade: how to use).
Silicate-silicone.

The difference between decorative plaster and ordinary material is the addition of mineral components, various fillers and additives:

As a rule, marble chips with fractions of various sizes are used as a filler.
The particle size determines the depth of the pattern and usually does not exceed 5 mm.

Note. The gypsum-based composition is used only for interior decoration in dry rooms.

Cement compositions can be used in any premises and for exterior decoration.
Acrylic and silicate-silicone compounds are used to create complex textures for both exterior and interior decoration.

The price of the mixture varies depending on the manufacturer, type, weight of the package and can range from 300 rubles for cement-based plaster and up to 2,000 rubles for a silicate-silicone-based mixture per 25 kilogram bag.

Application technology

So:

Finishing with plaster is not particularly difficult and can be done with your own hands:
It doesn’t matter what will be used - ready-made mass or dry mixture, decorative plaster is applied the same way.
The instructions for preparing the working mixture establish the proportion that must be observed when mixing the dry mixture with water.
Before use, it is necessary to prepare the walls or ceiling - remove the old coating, prime and level.

Advice. It is recommended to apply the first pre-coat before applying the base coat to avoid gaps. If you plan to apply a fairly thick coating, then careful preparation is not required; the plaster will hide minor defects.

Applying decorative plaster opens up unlimited possibilities in choosing the application method to create texture.

Plaster textures

However, there are several proven textures that look most advantageous in any interior:

Lamb - the result is a rough, evenly grained surface.
Fur coat is a rough surface with irregularities that imitate slight hairiness.
Bark beetle - the most famous texture, imitates the furrows of wood eaten away by insects.

Application instructions:

The work is carried out by sealing an area of approximately 0.5 square meters.
The material is applied with a spatula in an even layer of the required thickness.
After that, the desired texture is created on the surface using a grater or other tool.

For example, the “bark beetle” texture can be created by movements in a vertical, horizontal or chaotic direction. After the desired result is achieved, they begin to work on the adjacent site, without allowing any interruption in work.

Material consumption

The consumption of dry mixture of decorative plaster for each application method is individual and is determined by the texture, particle size and layer thickness.

Note. When applying the “bark beetle” texture, the depth of the grooves, and accordingly the thickness of the layer, is determined by the size of the solid particles in the mixture.

The approximate dependence of flow rate on particle size is given in the table:

Particle size, mm	Mixture consumption, kg/sq.m.
1,5	1,5-2
2-3	2,5-3
3-4	3,5-4

Color solutions

Dry decorative plaster is supplied in white color:

Looks most impressive in bed or ocher tones.
To obtain the required color, it is possible to tint the material in bulk.
For tinting, special pigments are used, mixing which in a certain proportion to achieve the desired shade.
Please note that the shade of the material on the wall may look completely different from the one in the container, so before applying it to the wall you should check the color on a test section of the wall.
Painting on the finished surface is also allowed. Almost any paint can be used for this.

When painting a plastered surface, use various techniques decoration - adding sparkles, showing protruding or recessed parts of the texture, glazing, etc.

Material protection and care

To impart additional decorative properties and greater resistance to external influences, special finishing materials are used - waxes, glazing compounds, varnishes.

Natural material based on beeswax or artificial wax gives the plastered surface water-repellent properties, reveals relief, adds shine and depth. The wax is sold ready-to-use. It can be transparent, pearlescent, with a honey or golden tint. In addition to factory colors, wax can be tinted to the desired shade.
Glaze is a translucent coating designed to add depth or additional shade. Glaze can be transparent, white, or have shades that imitate gilded, silver or bronze surfaces.
Ordinary acrylic varnish can also be used as a protective layer, giving additional shine or matte.

Note. To apply them, use a brush, rubber spatula, sponge or fur mitten. After drying, the wax or varnish forms a durable protective film.

The dried coating can be washed using a soap solution or moderate detergents.

The catalog of the online store Skladom.ru presents high-quality and affordable interior plasters. Such compositions are in great demand among home and professional craftsmen. That is why manufacturers produce dry construction mixtures for capital and cosmetic repairs using modern technologies and in a wide range.

Areas of use

For bathroom. Particular attention is paid to finishing rooms with high humidity levels. Cement-based mixtures are designed specifically for wet rooms. They have a porous structure, therefore they promote good adhesion between the tiles and the wall. In addition, the cement coating can withstand the weight of heavy porcelain stoneware and will not crack under pressure and will not move away from the walls.

Materials that do not retain their original properties during temperature changes and high humidity should not be used, as repairs will soon need to be made again. These include gypsum compositions. Of course, there are internal moisture-resistant gypsum plasters, but they are used with caution and careful adherence to the rules. The price for such compositions is significantly higher than for conventional gypsum mixtures.

For ceilings and walls. In dry rooms, gypsum interior plasters are usually used to level walls and ceilings. They are noticeably lighter and cover the base better than cement plasters, so using them will be more convenient for leveling ceilings.

After using cement plasters, it is necessary to apply putty (laying tiles can be done without putty). For plaster, a putty layer can be applied only before painting.

Work with gypsum and cement internal plasters can be done either manually or using special equipment. Some manufacturers produce mixtures specifically for machine application.

Plaster mixtures for interior work are a popular and inexpensive way to level the surface of walls. Before starting repair and construction work on finishing walls using the plastering method, it is necessary to have a brief basic understanding of the types of construction dry mixtures for plastering inside buildings and premises. An incorrectly chosen plaster mixture will not give the required result and you can only later regret the time spent and wasted money.

Types of plaster mixtures

Relatively recently, walls were plastered using mortars that were made independently from individual components. This preparation process was inconvenient, labor-intensive and required additional labor for the delivery of material for the solution and its preparation.

With the development of modern construction technologies, manufacturers began to produce a wide range of building mixtures in the form of ready-made materials for plaster and dry mortars.

Composition of dry plaster mixes

Dry bulk mortars for plaster are classified according to the base filler material and are divided into the following types plaster mixtures:

mixture or the well-known and popular dry “cement mortar” in construction. Probably every person has heard about this type of building material and knows that it is a very strong, durable, durable and inexpensive type of plaster. To obtain the desired consistency when leveling walls, dilute with water in a certain proportion. The resulting solution has a universal purpose; it can be used for all types of plaster with the exception of residential premises.
dry plaster mixture includes a component such as slaked lime. As you know, lime has plasticity and antibacterial properties. Thanks to this additive, the cement-lime composition can perfectly level walls wet areas. It is also convenient to work with because of its elasticity and good adhesion to any surface.
dry plaster mixtures are made on the basis of building gypsum with mineral additives. Gypsum-based plaster is ideal for plastering interior walls of residential premises. This mixture is easily applied to the walls; the surface of the plaster quickly hardens and after drying is white. If semi-dry gypsum plaster is moistened with water and rubbed with a polyurethane plaster float until smooth, you can get a smooth, durable, glossy surface that does not need to be covered with putties and can be directly glued to wallpaper. The disadvantages of gypsum plaster include the speed of hardening of the finished solution.

The dry plaster mixture is packaged in double paper bags of varying volumes and weights. A standard bag of this finishing bulk material weighs from 20 to 25 kg. For small volumes of wall surfaces, you can find packaging of 1 and 5 kg.

Selection of dry plaster mixtures for leveling walls

When choosing a mixture for plastering work, you should pay attention to the material of the walls intended for plastering. If the walls are made of brick, then it is possible to use all types of dry mixtures: from cement-sand to gypsum plasters. If the wall is made of concrete, then the best option would be to use gypsum plasters. In construction, it is allowed to use cement or cement-lime dry mixture for plastering concrete surfaces only over a metal plaster mesh previously fixed to the prepared surface. When plastering wooden walls, it is best to opt for gypsum dry plasters.

An important factor in choosing dry mixtures is the time for finishing work. The lime mixture is the most convenient to work with; it can be left unused for several days.

Gypsum plaster quickly “sets” and loses its properties, so you will have to work with it very quickly.

Comparative characteristics of plaster mixtures

As already mentioned, dry plaster for interior work is used to level and create a protective coating on the surface of walls. You can compare these Construction Materials by main technical specifications and after that make the right choice in favor of one or another plaster mixture.

Vapor permeability of dry mixtures is an important indicator that characterizes the ability of plastered surfaces to transmit or retain water vapor. For cement, lime and gypsum dry plasters it is almost the same, so moisture will not accumulate inside the plaster layer from all types of solutions.
The material consumption of dry mixes varies. Gypsum solutions have a minimum consumption, about 10 kg per 1 m2 with a plaster layer thickness of 10 mm. For cement and lime mortars, the consumption is from 10 to 20 kg for the same area.
The hardening time of mixtures for plastering works varies for different types material. A solution of a dry cement-sand mixture “sets” after 2 - 3 hours, and a gypsum solution hardens after 1 hour. This means that the gypsum mixture must be mixed in small portions and immediately applied to the walls.
Specific heat capacity is one of the important technical indicators when carrying out repair and construction work. Lime-based mortar will be the warmest of the entire family of dry mixes, and cement-sand mortar plaster will be the coldest.

Thus, a house or apartment where the internal walls are plastered with lime mortar will be warm and comfortable with a microclimate pleasant for humans.

It is rare to find perfectly smooth wall surfaces in private houses or apartments. Depressions, vertical deviation, curvature - such defects in internal walls are a fairly common phenomenon that almost every homeowner has encountered.

Plastering or leveling curved surfaces can present some challenges in applying the plastering mixture and creating a smooth, straight wall.

To significantly facilitate this difficult process, it is recommended to use plaster beacons made of galvanized metal slats in the form of a profile. Such beacons are attached to the wall using a plaster mixture (preferably gypsum) strictly level and at a distance of up to 1 m in width. The construction plaster mixture is applied to the wall between the beacon slats and leveled using a metal plaster rule, while the excess mortar is evenly distributed over the surface.

Another option to make finishing work easier using plaster mixtures would be to pre-glue the surface of the walls with a plastic reinforcing mesh, over which it will be very convenient to apply layers of plaster.

A small addition of detergent directly to the mixing water will allow you to increase the plasticity and increase the mobility of the plaster mixture.

You can familiarize yourself with the instructions for plastering beacons by watching the video:

Ready-made plaster mixture

Ready-made wall plaster is a ready-to-use, homogeneous construction solution for plastering all types of surfaces. Ready-made plaster is sold in plastic and metal buckets or cans.

This solution does not need to be diluted with water; you just need to open the lid, mix the finished mixture with a construction mixer with a nozzle, and it can be applied to the wall, which must first be cleaned of dust and dirt. Some manufacturers recommend that before using ready-made solutions, pre-treat the walls with special primers, which will enhance the decorative effect of a particular plaster. The price of finished plaster is significantly higher compared to dry mixes, but the consumption is 2-3 times less.

Ready-made plaster has only a decorative purpose and is not used for leveling walls.

Types of ready-mixes for plaster

Since it has already been said that ready-made mixtures are used to create decorative coatings on walls, they can be divided into several types based on the type of filler and the texture of the created surface:

Textured plaster contains natural fillers from flax fibers, wood fragments, marble or granite chips. After applying the mixture, the surface of the walls has a pronounced texture. An example is the popular decorative coating “bark beetle”, which imitates tree bark.
Structural plaster contains quartz sand. It is applied in a thin layer and, if desired, such a coating can have a smooth and even or pronounced textured appearance. The well-known “fur coat” plaster is a classic example of structural plaster. This ready-made plaster mixture has such a remarkable indicator as moisture resistance and therefore it can be used for plastering walls in rooms with high humidity.
Venetian ready-mix is the most expensive type of ready-mix plaster; it is made on the basis of marble and, after application to the walls, looks like natural marble.

All types of ready-made plaster mixtures are united by the method of their application: using steel spatulas, combs and brushes - brushes.

Advantages of ready-mixed plaster

Ready-made plaster mixture for interior work has many advantages:

Highly decorative and aesthetically pleasing finished wall coverings.
The finished mixture can be applied to any walls made of concrete, brick, wood and plasterboard.

Ready mixes for plaster have two disadvantages - they are high cost compared to dry mixtures and the short shelf life of the mixture in an open container.

Ready-made mixtures for plasters can create a unique and very beautiful design for apartments or private houses.

When choosing plaster mixtures for repair and construction work, preference should be given to well-known brands and trusted manufacturers of mixtures specializing in the production of finishing materials.
