Disadvantages of decorative plaster. The whole truth about wall decoration with decorative plaster

It seems to the ordinary buyer that wall plaster is a specific type of finishing material. Often, ignorance of the classification stops when buying. In fact, plaster mixtures cover a wide range of materials. They differ in composition, purpose, service life. Even a little knowledge from this area will allow you to buy desired view raw materials.

Features and purpose

In the classical sense, plaster is everything that can be coated with walls during the construction process. These are mixtures developed in accordance with the requirements of GOST. Their basis is an astringent. In addition to it, the composition includes various additives. Most of them have a narrow purpose, which explains the wealth of choice.

Each case has its own nuances of using and preparing the base. However, the basic rules for such materials are the same: they are applied to the wall, then leveled.

The purpose of the mixtures is extensive, it depends on the composition of the plaster. Due to it, mixtures can be used for finishing unheated premises (for example, an attic). Other components even provide for operation in harsh conditions. They withstand winter temperatures down to -40 degrees. Others are designed specifically for wet rooms where the resistance of finishing materials to critical conditions is necessary. Some are resistant to temperature changes, differing in a special structure.

Depending on the composition, they differ in starting and finishing compositions.

Draft

Rough plaster is understood as a mixture, which itself is the basis for the finishing material. Usually she trim the surface. Outwardly, it is often unremarkable, its appearance is far from aesthetic. It is a viscous or sandy mass of a gray or clay hue.

Such materials are widely used as base preparation. They are appropriate for leveling the surface, masking potholes, chips, sealing cracks.

This material works as a dental solution for filling and building up teeth. The composition includes a binder that prevents further destruction of the walls. They fill the gaps, then trim and grind the surface. The difference is the fact that this plaster needs a beautiful material on top of it. It can be paper (wallpaper), drywall, lining, wood, plastic, glass (mirror), laminate, siding, metal or finishing plaster.

Finishing

Under the finishing material, it is customary to understand compositions with a decorative purpose. They are not the basis for another finishing material. This is the main difference between the two types of plaster. They are not used as a draft because of the higher cost. As a rule, the price of such plaster is an order of magnitude higher.

The compositions also differ externally. Their structure is viscous, elastic, but the granularity is much smaller. The grains of sand are not visible, they cannot be felt when rubbing the mass between the fingers. Such a mixture falls on the surface differently. Working with her is pleasant and easy.

Apply such compositions in a thin layer. Often to get best result or a special effect in finishing one material is applied in 2 - 3 layers. Separate varieties cover the walls up to 5 times, mixing different shades in order to obtain a unique appearance. The thickness of the layer in this case should not exceed 1 mm..

To achieve this, the method of applying the mass is chosen automated. It allows you to speed up the spraying procedure and saves up to 40% of the raw materials used.

What's better?

It is impossible to single out one of the species or name a universal one for any conditions and needs. For this reason, it is impossible to say which one is better. If you use the plaster mix for other purposes, it will not be durable. This usually leads to its flaking from the base, even with high-quality surface preparation and increased adhesion. If the plaster moves away from the wall, it will not be possible to correct it imperceptibly.

The base color of the plaster depends on its composition (base and additives). For example, sometimes the mass has a concrete tint. If it contains clay, the color may be off-white or brownish. Lime gives White color. The gypsum-based mass, when dried, brightens and becomes bleached sulfur. Decorative mixtures are distinguished by their white tone with varying degrees of purity.

Typically, a manufacturer's brand provides its products with a number of recommendations for the convenience of the buyer. The marking indicates for what type of work the material is intended (for example, leveling, interior decoration). The type of recommended surface is also marked on it (for brick, concrete bases, foam blocks, foam plastic finishes). You need to choose the one that corresponds to the specific basis and type of work.(external or internal, preparatory or finishing).

Even a process such as plastering a doorway has material requirements. The solution used when installing a double-glazed window also differs. One type cannot be replaced by another: the mass will not hold as it should. The sealing mortar will not replace the decorative mixture.

Each type is designed taking into account the different thickness of the applied layer. It differs in terms and conditions of drying.

Advantages of decorative mixtures

Finishing mixtures used to decorate walls have a number of advantages:

They are aesthetically pleasing. Plaster is an alternative to many finishing materials. The idea of decorating her walls is fresh, therefore it is in demand.
Mixes are a quality product. They are performed on modern equipment using new technologies. This improves the performance of mixtures.
Plaster solutions are environmentally friendly. They are safe even for allergy sufferers, during the service they do not emit toxic substances into the air.
Plaster may have different colour. The composition provides for a change in color due to the usual color scheme. You can change the saturation of the color.

Most of the developed solutions absorb noise. This allows you to reduce annoying noise from neighboring apartments or the street.
Materials are wall insulation. Even a thin layer helps to reduce heat loss, which is noticeable in the cold season.
PVA glue can be added to any type of plaster. It improves the quality and performance characteristics of the compositions.
Such materials are base correctors. They are able to trim the surface, if it is almost flat.
Mixes are variable in the choice of effect. You can choose an option for a specific interior style, indicating that it belongs to it.

decorative material strengthens the base. The structure is not destroyed. The finish is applied manually and by machine.
Blends are durable. With the right application and decoration technology, they will last more than 10 years without the need for adjustment.
The materials are UV resistant. They do not fade under the sun, whether it is a finishing facade raw material or a solution for interior work.

The composition includes additives that increase the life cycle of the plaster mass. This increases the time of use and adjustments if necessary. You can apply more solution to complete the drawing with whole, continuous lines.

In addition, decorative plaster is fireproof. It is distinguished by unlimited possibilities for imitating different textures.

disadvantages

In addition to the advantages, plaster has disadvantages:

Not all materials are resistant to condensation. Over time, even cement masses are destroyed from it.
No type of composition can be applied in a thick layer. The time for work increases, non-compliance with the technology leads to cracking of the plaster, the wall may be deformed.
The consistency of any mixture must be correct. Its modification will cause a deterioration in the appearance of the coating, complicate the application of the composition to the walls.

Some categories of compositions do not meet the stated requirements. More often this is due to the counterfeiting of goods of famous brands.
Separate mixtures are washed off with each cleaning. Some compositions have to be coated with diluted varnish, others cannot be protected from abrasion.
Decorative coatings with relief are difficult to maintain. Dust settles into the recesses, it is not easy to remove it, sometimes it hurts the skin of the hands.

Types and properties

The range of plaster products covers a wide range of coatings. You can buy on store shelves different variants- from elastic and flexible to vapor-permeable velvet.

For example, today plaster is in demand among buyers:

sanitizing;
perlite;
polymeric;
gypsum-perlite;

cement;
plaster;
magnetic;
calcareous.

Clay plaster mass is made independently. Today it is rarely used.

According to the binder, the mixtures can be acrylic, mineral, silicone and silicate.

Acrylic

Acrylic coatings are characterized by a special elasticity of the applied layer. The basis is a high molecular weight polymer. The origin of the dyes included in the composition can be organic and inorganic. These are decorative solutions, on store shelves they are presented in the form of ready-made paste in buckets. The disadvantages are a small vapor capacity and instability to ultraviolet rays.

mineral

The main binding component of mineral solutions is cement. These are formulations that are sold in powder form. They are distinguished by a relatively affordable cost, designed for bathroom walls due to moisture resistance. For the same reason they are used in the decoration of facades.

Such compositions are not afraid of weather factors and season changes. They are considered one of the best environmental materials. They are not subject to fading, but are vulnerable to significant mechanical shocks.

Silicone

Such analogues are based on synthetic resinous substances. This is a simple and easy-to-use finishing material. Depending on the composition, it provides for use inside and outside the building and, unlike analogues, repels dust and is resistant to the absorption of foreign odors.

The plaster is plastic, in the process of application it creates a moisture-resistant protection, due to which is an suitable material for use in the decoration of wall ceilings in bathrooms, baths, dressing rooms. Counts good choice for rooms with high humidity.

This is especially true for apartment buildings with broken construction technology, including a ventilation system that is insufficient or completely absent.

silicate

Such options differ from the general line of the main component in the form of liquid glass. It is a mixture of alkaline potassium carbonate, quartz sand and potassium hydroxide. Along with the water-repellent ability, silicate types of plaster mixtures are characterized by special strength. After drying, such a layer is distinguished by reliability and resistance to mechanical damage.

This material excludes rotting of the material for which it is the basis. It is resistant to mold fungi, sufficiently viscous and refractory. On the shelves of shops it is presented in the form finished product with different color.

The silicate finish is considered by craftsmen to be one of the best, reliable and durable. It is designed for 30 - 50 years of operation.

Release form

The building materials market is full of offers for different tastes and budgets. Among the wealth of choice, it is easy to get confused. All products can be divided into 2 types according to the form of release. These are raw materials in the form of a semi-finished product and ready-made plaster materials.

Dry plaster compositions are presented on the modern market in the form of a powder of various types and compositions. They are not bound by gypsum fiber sheets either. Most often they are sold in standard bags with a volume of 25 - 30 kg. Sometimes the packaging is smaller (2, 5, 10 kg). The components are balanced in such a way that the mass meets the stated requirements and practicality. For work, raw materials are prepared using ordinary water at room temperature.

The manufacturer indicates the amount of water on the package itself. Usually 0.2 liters of water is used per 6 kg of the mixture. However, in addition to the basic components, trademarks provide for the combination of components with additives as desired. More often it is color, since the addition of other inclusions will not be transferred to necessary measure. For this reason, certain types of coatings are decorated after they have dried in different ways.

Ready mixes are a self-sufficient finishing material. Unlike dry analogues, this plaster is exclusively finishing or decorative. Release form - plastic buckets of different sizes (5, 10 kg and more). It does not need to be diluted, the mass has the desired consistency, resembling a paste. Often it is already painted, which increases its value.

but color solutions such material is often wished for better. You can find on sale only pink, beige or wood finishing material. Of course, the finished tone is convenient if there is a large amount of work to be done. No need to tint and select each portion of the mixture. However, often the buyer wants to decorate the interior of the home with a coating with a touch that is not commercially available.

An ordinary buyer does not always know that not a single plaster composition is kneaded all at once. Even an experienced craftsman with professional equipment does not use a composition on all walls, the life cycle of which is short. Dry mix would be the best solution.

In order not to doubt the fit of the shade, you need to write down the amount of color and use the measure for each batch.

The finished mass is often thicker than the powder counterpart. When a container is opened, its properties begin to change. Dry varieties also dry out, but their life cycle is somewhat longer. Other factors also speak in favor of the powder. Such material is cheaper, it is easy to maintain, and when using it, excess plaster is almost impossible. This is due to the small portions of the batch.

All types of plaster material can be divided into several categories.

Special

The category of special plaster coatings includes varieties with special fillers. This is a kind of shielding insulating layer. One of the varieties of such material is X-ray protective mixture.

In addition to the basic set of requirements stated in GOST, it has protection against electromagnetic radiation and has an inexpensive price. The thickness of the protective coating is usually small. Work must be carried out quickly, since docking in this process is unacceptable.

An interesting option plaster mixtures is an acid-resistant variety. It is used mainly at facilities where walls are exposed to aggressive acid fumes (in industrial workshops, laboratories). The basis for such raw materials is a product on liquid glass. The composition includes quartzite and stone flour.

To prevent the glass from collapsing due to exposure to air, another 1 layer of plaster is applied on top of such a coating. Usually it is a cement-sand based product. followed by ironing.

Decorative

This category includes one of the best lines of plaster mixtures. These are special mixtures with the best decorative possibilities. Such plaster can be finished or powdered. In the second case, the master has the opportunity to implement the design idea. Particularly advanced finishers sometimes make unusual types of plaster material from classic putty.

Trademarks offer to the average buyer to make their work easier. On sale you can find mother-of-pearl, Italian, Viennese and French plasters. Remarkable roller texture, latex plastic, wet silk. Each mass is different in color, effect and method of application.

For example, in order for Versailles plaster to be transferred correctly, it is sprayed after drying with silver. Venetian is applied in several thin layers. When applying each layer, alternate tiny portions of the plaster mass with stretching them into each other.

One of the fashionable designs is the craquelure technique.(effect of cracks with a glimpse of the fundamental tone). "Bark beetle" conveys the texture of wood carved by a beetle. "Fur coat" obtained by rolling with a pile roller on a fresh plaster surface.

To give texture, you can use different techniques. Rollers wrapped in cellophane, crumpled newspaper, nails, fingers, special plastic trowels and trowels are appropriate. The best decoration of such surfaces is stucco molding over the cladding.

facade

This category includes formulations for exterior finish walls. They differ from internal counterparts in resistance to all weather factors. As a rule, their structure is not destroyed by frost, gusts of wind, precipitation, ultraviolet radiation. These are especially durable types of plaster material. Their main criterion of demand is durability.

However, these types of material are particularly demanding on the choice of base. Options for cellular and lightweight bricks will not withstand heavy compositions. It will not work for them to level such a base, because cement-sand or cement-lime masses can cause deformation of such coatings. Externally, the plaster coating will begin to tear away from the base, covered with cracks.

Acoustic

Acoustic plaster is a special mixture whose task is to reduce noise. Previously, such material was used mainly in the decoration of industrial workshops, as well as cinemas and concert halls. Today, this raw material is indispensable in cases of curvilinear architectural forms. They fully replace acoustic systems where it is impossible to make them due to design features buildings.

These varieties are applicable for decorating rooms with boominess. Usually this is wall decoration in rooms with floor tiles or marble. Such options differ from the basic composition by the inclusion of pumice, expanded clay, slag, perlite or vermiculite. The density of the mass with an acoustic effect varies between 500 and 1300 kg/m.

However, it is undesirable to paint or whiten such plaster: this reduces the level of sound insulation.

Heat shields

Such variants of plaster raw materials prevent heat loss. They isolate the premises or communications. The composition may include granulated polystyrene foam, hydromica or perlite, which is a mineral of volcanic origin. These varieties in the language of builders are called warm.

A characteristic feature of such compositions is a small weight with a significant volume. The heat-shielding plaster itself is light, it is able to maintain the desired microclimate indoors. This often eliminates the need additional insulation facade surfaces mineral wool or expanded polystyrene. The texture of the material is pleasant to work with.

Waterproofing

Waterproofing plaster mixture is a material based on waterproof polymers. Such options are used to protect buildings from moisture and steam. They are relevant in the decoration of bathrooms, combined bathrooms, balconies.. In addition, moisture resistant waterproofing according to fit to work in basements, isolation from moisture of walls of pools, baths and saunas.

Let's apply this material where the plastered surface is subjected to hydraulic loads from constant contact with water. The binder for such plasters are resins based on polyurethane or acrylic, as well as epoxy analogues.

An interesting technique for enhancing adhesion and increasing water-repellent properties during surface treatment is the application method. Such solutions are applied by means of a tonkret gun.

Quality difference: where is it used?

By technological map plaster can be made in 3 versions, which explain its qualitative characteristics. It depends on the application method.

Work with plaster masters are divided into 3 stages:

splatter(base layer for plaster);
priming(trim layer);
covering(finish coat).

Simple

Such a solution can be applied in 1 layer with or without grinding in non-residential premises. There is no need for cover here. Additional layers are not needed: the coating is triturated immediately after applying the mass. To do this, use a plastic grater. The process is far from simply smearing the material on the wall.

The cement-lime mixture is stretched without beacons, leveled with the rule. The maximum layer thickness can be up to 2 cm. The texture of such compositions can be rough, but always smooth.

improved

Such a mass is applied in 3 layers (spray, primer and coating are included), using in residential and non-residential premises. The consistency of the first is more liquid, so it is necessary to enhance adhesion. Wherein layer thickness should not exceed 0.5 cm.

The main load is created on the soil layer. Its thickness can reach 1 cm, but no more: you need to leave it for the third layer.

If you initially plan a thick layer, you can not do without a reinforcing mesh. Suitable composition based on gypsum, lime.

high quality

This variety differs from the previous ones by the identity of all layers. It characterizes the accuracy of the work carried out. These are polymer mixtures with installation on beacons. In the classical method of work, they are fixed by level and cord, achieving vertical and horizontal accuracy. This best variety for interior wall decoration.

The technology includes 3 stages (spray, primer and coating). Usually, lime-based compositions are not used for such work. Grinding is done with a metal spatula or trowel.

The main difference from all types is the size of tolerances in quality control.

Instruments

Working with plaster requires the presence of certain equipment. In each case, it may vary, depending on the type of material used.

The basic kit includes:

container for mixing;
construction mixer with a special nozzle;
container for a set;
spray tool (hopper, airbrush);
trowel or trowel;
rule;

guides;
trowel;
level;
roulette;
pattern forming tool.

In addition, you may need beacons, a grinder or metal shears, a Phillips screwdriver, drills, a hammer and a puncher.

Application

You can use plaster in the construction and decoration of structures of any type. Its use is appropriate for work in multi-apartment and private (country and country) houses. To understand what kind of mass is needed, it is worth starting from the conditions in which the material is planned to be used.

It is useful for industrial facilities, new buildings, as well as public buildings:

polyclinics, hospitals;
pools, baths, saunas;
administrative institutions;
hotels, clubs, cafes;

cinemas, studios;
educational centers;
sports halls;
educational institutions (kindergartens, schools, institutes).

On the market, such products have their own classification. To save time on studying the assortment, it is worth deciding in advance on the type of surface and choosing desired material. Sellers will always tell you which vapor-tight mixture is better, explain the subtleties of products with sawdust, and grain differences. They will definitely focus on best qualities goods, especially if the plaster is refractory, cork, X-ray protective or voluminous.

Almost always note the special properties ready mix and its special effect. Such material gives a lot of possibilities for design. It is comparable to a canvas, on which you can convey the inner world through curly lines or paintings using material of different shades. The basis for the images is a smooth type of finished surface. This is the finishing touch.

Wall decoration with plaster will be durable if you choose it correctly according to the type of base. In some cases, it must be vapor-permeable, and sometimes vice versa, vapor-tight.

Brick

Depending on the type of work (internal or external), it is necessary to plaster brick walls different materials.The right type of raw materials are cement-sand mixtures. Indoors, you can use a variety with an admixture of lime.

The maximum allowable layer thickness is 3 cm. Under the plaster, a chain-link mesh should be fixed. Due to it, the solution will be better kept on the surface.

When adding lime, you need to take not a dry component, but a lime dough. Finishing facing brick a little more difficult. Here, the usual chain-link is not always effective, so you have to select the reinforcing mesh very carefully. Besides, the surface must be primed before applying the solution.

The main composition of the mixture is sand, cement, lime paste and water for dilution.

Concrete

Surface concrete base may be smooth or rough. In the first case, to enhance adhesion, it is necessary to treat it with a primer with quartz chips. As a plaster, a mixture based on cement with the addition of gypsum is used.. Its inclusion enhances adhesion.

For interior decoration, you can use a composition of 3-4 parts of lime and 1 part of gypsum by stirring it with lime liquid.

If the walls are rough, there is no need for complex preparation. The plaster will lie on them well and will hold better. For wall decoration outside, it is better to use cement varieties. It is also possible to process wall ceilings inside with gypsum material.

To enhance adhesion and make the structure homogeneous, it is better to treat the walls before plastering with a primer with a high penetrating power (“Betonokontakt”).

Wood

Wooden house needs special attention when decorating the walls. The mass should protect the wood from rotting, mold formation. In addition, it must be resistant to rodents and termites. Plastering a house from a bar can be carried out a year after construction. It is necessary to wait for the end of the shrinkage process. Facade plastering is usually done with a lime-cement composition..

Besides, use clay formulations. Of all the varieties, it is more suitable for conditions high humidity, compatible with any temperature conditions region. Partitions are finished mainly with lime-gypsum composition. Gypsum analog is suitable only for interior decoration. It cannot be called the best; at high humidity, it exfoliates from the base.

To enhance the decorative effect, after drying, the plastered surface is treated with CMC glue or wax mastic.

GVL

Performing plastering gypsum fiber sheets necessary for sealing and leveling tile joints. It allows you to enhance the adhesion of the GVL base to the finishing materials applied to them. This is also necessary to equalize the absorbent capacity of drywall. For this use dry plaster mixtures on a gypsum and polymer basis and ready-made analogues from polymers.

The fraction of filler grains can be different. It depends on the type of putty used. The layer can fill only the microrelief or it is used as a starting leveler. The putty is tightened in such a way that the seam is almost invisible. Typically, the layer thickness does not exceed 1 mm.

Life cycle material is limited, so you need to apply plaster quickly.

Under wallpaper, painting, tiles

Finishing materials are used to prepare the base for further finishing. Plaster for painting should be fine-grained. These are compositions based on gypsum or polymers. In fact, this is the basis in the form of volumetric plaster, which is painted. Such a decorative technique looks unusual, but it allows you to update the background of the wall ceilings and mask the correction if you have to dismantle the damaged area.

Usually for such coatings use paint on water based. Paint the dried wall with a roller, rolling it over the entire area. If you need to give the painted surface a slight touch of vintage, the protruding dots are sprayed with a silver sponge.

Varieties for wallpaper - gypsum compositions with a pleasant texture. They allow fine finishing. In rare cases, its thickness reaches 5 mm.

If the percentage of humidity in the room is high, cement mortar has to be used instead of gypsum-based materials.

He is not afraid of moisture and dampness, is a universal wall leveler. However, if the fractions in its composition are large, after such plastering it is necessary to use putty (for example, oil or acrylic).

Under the tile use classic cement mortars in bags. It’s easier for a simple layman to recognize them by the mark “tile glue”. Outwardly, it is a gray loose mass that must be diluted with water. The granularity of the mixture depends on the sand. The consistency is selected according to the indicated marking. The composition should not drain from the walls.

In order to avoid rejection of the material from the walls, the formation of cracks, craftsmen add PVA glue to it.

On other surfaces

In addition to traditional materials, today plaster is bought for wall decoration from:

aerated concrete;
foam concrete;
penoplex;
expanded polystyrene;
OSB-plates;
gas silicate blocks.

It is rarely used for finishing adobe walls. tongue-and-groove blocks, from which the structure is built, does not need to be plastered. It is believed that putty is enough for them, and the surface is already even and smooth. Other options are more suitable for accentuating small areas, rather than monolithic coatings around the perimeter. Stucco for penoplex should be light.

The color mixture is made on an acrylic basis with the addition of marble chips. It is good for finishing mineral surfaces. Differs in water-repellent properties and hardness of structure. The range includes about 15 different shades, including beige, coral, terracotta, pink, mustard and turquoise tones. Such material is intended for internal and external works. It must be applied only on a dry base in a thin layer.

For finishing the walls of facades, a roller mixture of natural origin is good.. DSPs can also be used here (for example, when working with siding). Types based on cement and sand are good for eliminating obvious potholes and chips, curved walls in a private or apartment building.

For different types material suitable latex-plastic. It is used for interior decoration of traditional floor materials (concrete, brick, wood), as well as drywall, aerated concrete, foam blocks. This material is resistant to deformation. Due to its elasticity, it does not crack, it is distinguished by the texture of marble.

Metal- not the best type of base for plaster. If the issue of application is fundamental, you can not do without welding the chain-link mesh. So the plaster will hold better. Other ways of working are ineffective. Using a primer will not save the surface from cracking and peeling from the metal base.

Clay walls are plastered from the outside with lime mortars. Cement options are not suitable here. They will crumble due to their severity. Interior decoration can be done with a gypsum mixture. Clay can be white, red, gray and yellow. The reinforcing component of the mixture is sawdust. Due to them, the composition becomes more reliable.

More and more people are abandoning classic wallpapers in favor of interesting and original materials. Decorative plaster one of the types finishing walls, which is gaining more and more fans.
With the help of decorative plaster, you can create a unique pattern on the walls. There are masters who can paint beautiful panels on the walls using this material. Remarkably, it is almost impossible to repeat the same pattern, which gives us a guarantee of uniqueness.

Advantages of decorative plaster:

Original design solutions. With this material, you can create truly unique walls in your home. It's beautiful and unusual.

Strength and durability. If the material is applied correctly, in compliance with all the manufacturer's recommendations, then the walls will delight you. long years. Decorative plaster is resistant to mechanical damage, practically does not crumble and does not crack.

Masking wall imperfections. Even if your walls are not perfect, decorative plaster will hide it. Of course, large cracks and irregularities will have to be processed, but not necessarily brought to the ideal. However, for Venetian plaster, this statement is not true.

Suitable for any surface. Decorative plaster is suitable for wood, concrete, brick, metal. Almost any wall can be decorated with this material. There are types of plaster that are suitable for work outside the building.

Persistence. Decorative plaster is frost-resistant and moisture resistant. Including it has the effect of soundproofing.

It's ecological pure material. The composition of decorative plaster contains only natural ingredients that will never harm human health.

Disadvantages of decorative plaster:

High price. Like it or not, but the material itself is quite expensive. At the same time, in addition to the plaster itself, we need related products. For example, paint, special application tools, etc. If you decide to invite a professional for finishing, then this will also cost you a pretty penny.

Difficult dismantling decorative plaster can also be attributed to the minuses. If you decide to make repairs and dismantle this material, then you will have to sweat. However, this can be called the reverse side of the medal of strength and durability.

Careful preparation of the base may take you some time. The wall before applying the material must be cleaned to the ideal, nowhere should there be a risk that something will fall off. The primer, which is a prerequisite for the preparation of walls, is a tool for tighter adhesion.

Quite a lot of time you will have to spend to decorate the walls with this material. After preliminary preparation of the walls, the application of plaster begins, which sometimes takes several days. Some types of this material require application in two layers, while the first must dry completely.

Difficult to do on your own this wall decor. Of course, with simple options for applying such plaster, you can handle it yourself. But it is the specialist who will be able to create a unique, artistic work on the walls in your home.

We can definitely say that despite the existing shortcomings, decorative plaster is stylish and nice solution for your apartment.

It is not necessary to decorate every wall in this way. In interior design, more and more attention is paid to different wall designs in the same room. Try one wall decorative plaster, and glue the other with wallpaper or just paint. With the right combination of colors and textures, the room will sparkle.

If possible, invite a specialist to create a masterpiece on a small section of the wall. However, before you trust the master, be sure to check the reviews about him and clearly explain what you want to see. Such work is quite highly valued and you should not look for the cheapest option. If you choose a cheaper master, you can lose both money and material and trust in people.

Imagine, create your own unique design, create! All the best to you and easy repair!

One of the ways to quickly and efficiently level the walls in an apartment and any residential and non-residential premises is the use of mechanized wall plastering. What are the advantages of mechanized wall plastering, and what are its features in this material.

About plastering work in the apartment

What is important in finishing works ah in the apartment? Final result. After the completion of repair or finishing work, it seems not important how the work was carried out, only the qualitative result is important. In fact, it's quite the opposite. It depends on the type of repair and finishing technologies used. final result repair. This statement is especially true when you need to plaster all the walls of an apartment or house, while ideally displaying the geometry of the rooms and leveling the surface of the walls with high quality.

Only the plaster layer creates the basic basis for a quality repair.

Features of plaster work

Everyone knows that plastering is the most time-consuming, the most difficult and costly stage of repair and finishing work.

Classic way plastering works This is a manual plastering of walls, sometimes multi-layered, with all stages from spraying to pulling out the solution. If you need to plaster a large surface area, then manual plastering will drag on for a long time. According to the regulations, even an experienced professional will not be able to plaster more than 10 square meters. meters of wall per day, not counting the preparatory work.

A logical alternative to manual plastering is the use of mechanized wall plastering.

What is mechanized (machine) wall plastering

If you look at the process of plastering as a whole, we can distinguish three main stages of work:

Installation of beacons to indicate the level of the plaster layer;
Applying plaster to the surface;
Pulling the solution with a rule and smoothing it.

Do not think that the use of mechanized wall plastering will simplify all stages of plastering work. Unfortunately, beacons and solution extraction will have to be done manually anyway.

The technology of machine plaster mechanizes only the mixing of the solution, the supply and application of the solution to the surface. In fact, this is not enough. It is the mixing of the mortar, which always needs a lot for plastering, and its application to the surface is the most time-consuming processes.

Details about the technology of mechanized plastering on the website: http://shtukaturka-k.ru/

Advantages of mechanized wall plastering

Let's look at the main advantages of mechanized (machine) wall plastering.

Saving money. In fact, plaster mix for machine application is cheaper. Given the required volumes of the mixture, we get a clear cost savings.
The best quality solution. The mechanized method of plastering involves machine mixing of the mortar. Machine-mixed plaster mortar is of better quality and plasticity.
Rapid application of the solution to the surface. From the plastering station, through the supply hose and sprayer, the solution is applied to the wall. The pressure when supplying the solution allows you to tightly apply the solution to the wall, thereby eliminating air bubbles in the solution layer, and the constant supply of the solution reduces the time of applying the solution at times.

After applying the solution to the wall, it is manually leveled according to the previously installed beacons. As it dries, the surface rubs off. The quality of the mortar and the density of the application of the mortar, in some cases, make it possible to avoid puttying work.

In conclusion, a few disadvantages of mechanized plaster.

Cons of mechanized plaster

Work requires the presence of power at the facility;
Cost-effective plastering of only large areas from 100-150 meters.

With the help of a huge range of offered finishing materials for walls, you can get a unique design for any room. The most popular today is decorative plaster.

Decorative plaster can be attributed to one of the methods decoration walls. Due to its environmental friendliness, durability and ease of use, it is rightfully a worthy alternative to traditional wall coverings (wallpaper, painting, tiles). This material appeared relatively recently and has already been able to find its fans, thanks to its unique properties.

Decorative plaster is a heterogeneous paste into which various kinds of decorating additives are introduced. As a result, you can get walls in the form of natural marble, silk, granite or metal. In addition to its decorative purpose, it can also serve as a finish for walls that are planned to be painted in the future.

With the help of such wall decoration, you can create a unique interior and an individual focus in design.

Types of decorative plaster

Structural plaster ("bark beetle", "fur coat") - has a peculiar "appearance": the surface treated with the material has a heterogeneous, granular appearance. The basis is quartz granules. The material can be divided into coarse and fine-grained. By the way, the size of the structural grain varies from 0.6 to 3 millimeters.
Textured - a lesser known material than structural and mineral plaster. In its raw form, it resembles dough - a white mass that is tinted or covered with paint after application. The main advantage of textured plaster is its plasticity, with the help of which various effects are created - bas-relief, panels, etc.
"Venetian" plaster is a versatile material: on the one hand, it is able to imitate valuable types of stone, on the other hand, it is used by designers when creating drawings and other decor on the walls. It has certain difficulties in work: applying in several layers, grouting, etc.
Mineral plaster - based on crumbs, is often used when decorating a room. Among other things, it stands out for its durability, environmental friendliness and relative cheapness.

Advantages of decorative plaster

Like any building material, decorative plaster has its advantages and disadvantages. The advantages include:

Strength, durability, practicality. If the plaster is applied correctly, in compliance with all norms, then as a result you can get an excellent coating that does not crumble, does not have cracks or chips. Also, this material has good resistance to mechanical stress.
Disguise. With the help of decorative plaster, you can level the walls and mask minor bumps and cracks. For such purposes, the most suitable is plaster with the addition of cellulose.
Versatility. This material is suitable for various surfaces. It can be applied to wood, brick, concrete, metal, etc. It can be used both for interior wall decoration and for exterior work.
Resistance to external factors. Decorative plaster has such properties as frost resistance, moisture resistance and sound insulation.
Environmental friendliness. The composition of decorative plaster is made up of only natural ingredients. It is non-toxic and does not absorb harmful impurities from the atmosphere.

Disadvantages of decorative plaster

Despite all these advantages, decorative plaster has disadvantages. And the most important of them is the high cost of this material. In such expensive cost This product also includes the work of applying it, which requires special skill.

Difficulty of dismantling. It will take a lot of time and effort to remove decorative plaster.

surface cleanliness requirements. Before applying decorative plaster, the walls must be thoroughly cleaned and treated with a special primer. This is especially true for metal surfaces to avoid corrosion.

However, having a number of disadvantages, decorative plaster is a versatile material that can be very advantageously combined with other finishes, which makes it possible to implement the most daring and original design ideas.

Material classification

By their own internal characteristics decorative plaster is divided into the following types:

mineral;
acrylic;
silicone;
silicate.

Mineral decorative plaster for walls based on cement. As a rule, they are produced in a dry form and are subject to mixing immediately before starting work. These plasters are highly durable, perfectly resist moisture and have high vapor permeability. This material has a white color, after working with mineral plaster, you will have to paint the walls.

A huge plus of this material is the democratic price. The construction market offers expensive options for mineral plaster with big amount glitter and marble chips. Such mixtures are not combustible and are used not only in interior decoration, but are also great for facades.

The only disadvantage of mineral mixtures is low elasticity. Over time, microcracks and a variety of mechanical damage may appear on the coating.

Acrylic plaster contains a high molecular weight polymer - acrylic resin. The advantage of such mixtures is elasticity. They are very resistant to deformation of the base.

However, acrylic plaster also has a negative side - it is prone to easy ignition. Therefore, it is not recommended to use the material together with wool insulation.

silicone plaster. This material is based on silicone resins, with which excellent coating characteristics can be achieved. This type is considered the most modernized - the finished coating lasts a very long time, has excellent moisture resistance and elasticity. good adhesion and high level vapor permeability allows you to use the material for any base.

It can be used not only for interior decoration, but also for decorating facades, because this plaster is self-cleaning and easily resists atmospheric precipitation and harmful substances that fill the air.

The only drawback of this material is its rather high price and mandatory preparation before application. To prepare the walls, a special silicone primer is used, which also costs a lot of money.

silicate plaster. This material is made on the basis of "liquid" potash glass, most often used for exterior decoration, as it is considered unsafe for health. The material is quite durable, elastic and vapor-permeable. Silicate plaster is sold ready-made. It is also possible to choose a color, but the range of this material is limited.

Wall decoration with decorative plaster of this type requires certain skills and dexterity, since the material dries out rather quickly.

How to work with decorative plaster

Plasters are produced in various types. You can purchase a dry mix, which will need to be kneaded every time before starting work and work it out so that the material does not deteriorate. But the market also offers ready-made layers in buckets, which are ready for use and stored for a longer period.

Working with ordinary decorative plaster will submit even to a beginner, because it is extremely difficult to spoil such a coating. And there is no need to prepare the walls too carefully - it will smooth out all the defects by itself. Such decorative wall plaster will also give a flight to your design ideas.

Wall preparation

It is necessary to thoroughly clean the wall from the remnants of the past coating (paint, wallpaper, etc.). Exfoliated areas are removed, and the cracks are sealed. This will be enough for bark beetle plaster, but Venetian and some other varieties require a perfectly flat surface.

Minimum set of tools:

Spatulas of various sizes
Grater (wooden or plastic)
metal spatula
Tanks for solution and water
Roller for textured plaster

Applying plaster

The solution should be prepared based on the recommendations on the package, then you will get the desired consistency. Moreover, you need to prepare such a portion in order to select it at a time, because otherwise the solution will “grab” right in the container. This is a job that does not tolerate long breaks.

The plaster must be applied with a spatula. When it thickens a little, you can walk on it with a grater without undue pressure, creating the necessary pattern. It is better to practice in a small area first. To create a unique relief, a spatula, grater and own hands. You can use any improvised means.

Most often, beginners create rains of different directions on the walls, circles, waves, crossed lines. The most simple in execution is the horizontal relief. You can also use a special figured roller, then applying the pattern is much easier.

All this must be done at the maximum pace, because the layer of plaster dries very quickly. It is necessary to pay special attention to the joints of the sections in order to avoid sagging.

After complete drying (usually about 24 hours), the plaster must be treated with fine sandpaper, which will remove all excess.

Analogues of finishing materials that have appeared recently have not diminished the role of conventional plaster. There is nothing surprising in that, because it has not ceased to be a resistant and durable material, an excellent tool for leveling walls, a finish available to anyone. It is unfortunate that this preference does not apply to all types of plasters to a sufficient extent. Not so long ago, decorative plaster became available to the mass buyer. Among other materials, this one is one of the best, with undoubted advantages and original advantages.

Textured. Allows you to create a relief form of very different complexity. The main ingredient in the composition of the plaster is lime flour (sometimes a polymeric material), and marble or granite chips act as a filler.
Venetian. Transparent plaster that gives the impression of a wall made of marble. And to create magnificent paintings, color is added to it.
