Structural plaster - photo of finishing walls and facades with structural plaster. DIY structural plaster

IN lately The walls of apartments or offices began to be decorated more often with decorative plaster. It is convenient for finishing; some types of plaster can even be repainted frequently without changing the pattern of the walls. There are several types of it, one of them is decorative structural plaster.

First of all, you need to understand what kind of decorative plaster used for interior wall decoration is:

• textured;
• Venetian;
• structural.

Textured and structural plaster is characterized by roughness and unevenness, while Venetian plaster is smooth and has a glossy surface.

Textured plaster has three types:

• fur coat;
• lamb;
• bark beetle

This plaster will perfectly help hide uneven walls; they will not need to be leveled in advance. It is often used for finishing loggias and balconies..

The Venetian type is made on the basis of lime and marble chips. The surface, depending on the application method, will be either glossy or matte. Fireplaces are often decorated with this plaster to make them look like stone. However, it has a significant drawback - high cost.

Structural plaster is an inexpensive and original material , which has excellent performance properties, it is distinguished by a wide range of textures and shades and an attractive appearance.

Features and Benefits

Structural plaster is a heterogeneous mixture based on different components (binders and others). Among them:

• granules;
• flour;
• sand;
• synthetic and natural fibers.

With its help you can create decorative wall coverings on balconies, kitchens, bathrooms or toilet rooms, as well as residential premises.

The surface texture is directly related to the fractionation of the filler. Thus, sandstone or stone can be imitated using grain of the desired size.

Structural plaster has the ability to adhere well to different types of surfaces:

• brick;
• metal;
• chipboards;
• concrete;
• cement;
• tree;
• drywall.

Cladding has many advantages compared to other types of coatings. So, structural plaster has the following advantages:

Structural decorative plaster is good because its different fillers form one or another texture.

The material contains small fractions of the following elements:

Depending on the size of the fraction, the material consumption also differs. It can be 1−3 kilograms per square meter.

The texture of the wall has one form or another depending on the filler and the method of applying plaster. It may look like this:

• precious stones;
• stone surface;
• sand wall;
• cracked skin;
• fish scales;
• antiquity and more.

The cost and purpose depend on the type of structural mixture for the walls. Each type has its own unique properties. Among them:

• Mineral plaster - has the form of a white dry substance based on cement and lime. This option is the cheapest. Right before application, it should be diluted in water in the specified proportion according to the instructions for the material. Then it is stirred with a special construction mixer or a drill with a whisk attachment. This plaster is fireproof, environmentally friendly, but not elastic. Over time, cracks may appear;
• Synthetic - based on acrylic resin, it is elastic, durable and environmentally friendly. It goes on sale ready-made;
• Silicone - the main ones are polymer compounds. Features high performance characteristics(water resistance, vapor permeability, wear resistance, durability and more). Such a composition on sale may be ready for use and cost more than others. However, the high cost is entirely justified by the remarkable external effect and durability of use.

You should choose one or another variety in the store depending on your plans for repairs and financial expectations.

If you don’t want to spend money on a finished product, you can make structural plaster for interior work with your own hands.

To prepare a composition with a pronounced structure, prepare the following materials:

• 6 kilograms of dry putty;
• 2 liters of water;
• 0.2 kg of glue-plasticizer;
• fillers (optional - pebbles different forms and sizes, broken glass, foil, sand, parts of tree bark, beads, etc.).

To prepare the material yourself, you need to take a large plastic container and mix dry putty with water in it using a construction mixer. Then add glue and filler there and mix everything well.

If you have no experience working with decorative plaster, it is better to try the prepared composition on one wall in small room, for example, a small pantry or hallway. If the coating does not look as expected the first time, clean the wall and reapply the layer..

Finishing work

Regardless of whether you use a factory-made composition for finishing or one prepared yourself, you need to be able to apply it correctly.

Prepare everything in advance necessary tools for work:

• building level;
• plumb line;
• rule;
• trowel;
• scoop;
• wide and narrow spatulas;
• construction hammer;
• acrylic dyes or pigments;
• hard bristle brushes different lengths;
• patterned and textured roller;
• rubber and foam sponge;
• spray gun or texture gun (if a large area of ​​the wall will be processed).

Work begins with preparatory work. They won't take much time. You need to do the following:

• Remove the old wall covering, especially strong fragments are beaten off with a hammer;
• Use a file or putty to remove the most visible effects, such as cracks, unevenness or bulges;
• Clean the surface thoroughly damp cloth, it is allowed to use detergents to remove dust and dirt. Oily stains removed with degreasing compounds or acetone;
• Apply primer to the wall.

Don't try to make the surface perfectly flat. This makes no sense, since minor imperfections will be removed by a decorative plaster layer.

Algorithm of actions

Before starting work, add pigment or paint to the mixture and stir well. If necessary, the composition is used white. Remember that silicone painted plaster will make finishing faster and more efficient.

The stages of work are as follows:

After the structural mixture has been applied, it must be allowed to dry. The average drying time is about two weeks and depends on the level of humidity in the room, weather conditions, temperature and layer thickness.

All that remains is to complete the final finishing. To this end, carefully remove dust from the surface of the walls using soft fabric and sand it down with sandpaper. Clean again and apply paint if you previously applied the white mixture. And in order not to disturb the texture when painting, use a rubber sponge soaked in paint. After drying, saturate the walls with wax in one layer.

Decorating walls with structural plaster is excellent design solution, which will be appreciated by creative individuals and those who do not like routine and strive to experiment in everything.

Today, during renovations, it is often craftsmen opt for decorative structural plaster. Thanks to its special composition, it protects the surface, allows air to circulate, and also gives a special, unique, original relief.

Meaning and features

In addition, depending on the manufacturer and type of material, the composition may include wood fibers, mica and quartz.

They are used during finishing premises. The coating is based on a fraction of stone chips.

If you use the finest fraction, the surface will be smooth, but still, you will see small textured elements. If a plaster is used that contains slight granulation, the finish will have a relief coating.

It is optimal to carry out internal work with medium granular fractions. They lie flat on the walls and create an incredible pattern.

The color of the plaster is usually white, but not many consumers are happy with this. You can add the desired shade yourself. For this purpose, professional pigment is sold in stores; it is selected according to color scheme premises.

A small amount is enough to make the color brighter, the shade is adjusted as pigment is added to the mixture.

Structural plaster can be distinguished from other analogues thanks to:

• source material and color;
• viscosity;
• obedience of the mixture;
• stability of the finishing coating;
• thickness of the ball;
• hardening speed.

Most often, future repairmen purchase ready-to-apply mixtures, which are sold in plastic container already packaged.

The composition may include mineral components or synthetic materials.

Depending on the components included, the mixture will perform different functions. For example, the more minerals there are, the easier it will be for the walls to “breathe.”

They pass steam fairly quickly, but they often need to be additionally treated with paint or other coating to improve technical performance.

Also currently on the market there is a wide variety of dry mixtures packaged in paper bags.

To use them, simply dilute them with water.

If you pay attention to polymer plaster with special components and purchase it, you will soon understand how it is resistant to impact high humidity , promotes the death of fungi and stops the formation of mold.

Color abundance can be obtained in several ways:

• during production;
• before applying;
• after you have applied.

The first option is the most convenient to use, because no special preparation is required here, as for the latter, it can be purchased, as a rule, in the form of a regular paste white, which will be painted in parallel after creating structure and complete hardening.

Pros

Structural plaster composition characterized by a number of advantages that successfully distinguish them from a long list of other types of plasters. Some of the main benefits are described below:

• versatility. It is used not only for interior but also exterior decoration;
• ease . Ideally contacts and lays on any surface. Has good adhesion to cement, brick, concrete, wood and other surfaces that require treatment;

• masking flaws and irregularities. Created perfectly smooth coating on any wall;
• resistance to mechanical damage;
• ease of cleaning the surface from any contamination. In this case, the plaster will not be damaged at all. Cleaning is carried out with cleaning and detergents, containing no solvents;

• favorability to temperature changes. Ideally tolerates fluctuations between +38 and -55 °C;
• the material is very plastic. Thanks to this, it is very easy to apply it to the surface; it creates an original relief;
• coating strength. There is air circulation in the walls, they seem to “breathe”, which will prevent the formation of fungus;
• perfect relationship between price and quality.

Cons

Despite the fact that there are so many advantages, there is still one disadvantage: the very high price. Not every resident of the country can afford to carry out such interior decoration.

Species

Despite its versatility, structural plaster can also be divided into different types. Most often they differ from each other in the composition of the main ingredients.. The leading positions in the market are occupied by the following types.

It is used during interior work.

Its main ingredient is cement, so you can purchase the mixture in dry form, then it must be diluted with water immediately before application.

The only minor inconvenience when working with these components is the need for surface painting of the themes paint and varnish material what you have chosen. It is rational to apply it to any surface: concrete, wood, brick, metal; it is not exposed to water.

The composition included separate elements that prevent the well-known blurring, Thanks to this, the treated surfaces can be cleaned with water. This composition is an ideal heat insulator, and it is consumed quite economically.

Used for exterior and interior decoration.

Its use is as simple as possible; the material has unique adhesion to the mineral surface, regardless of its type.

Plaster can be used to treat any wall; it is not affected by temperature changes and moisture, but it can become deformed and lose its original characteristics when exposed to sunlight. This is why it is inferior to its mineral and silicate analogues.

Plaster is a universal finishing material that can be used for external and internal work.

It is characterized by excellent elasticity and adhesion. Complements well with almost all types of surfaces.

In addition, you will never notice dirt and dust on it, they simply do not accumulate there, and those that do get in can be easily removed using a damp cloth. Characterized by a huge variety of colors. This is what makes it easier for customers to choose; many colors are also divided into tones.

The base of the plaster may include water or a solvent.

It's worth looking at what you want to get as a result. If you don’t know how your room will look after applying structural plaster, be sure to look for relevant photos on the Internet or in special magazines.

Among the variety of finishing materials for construction on the domestic market, the most popular is considered to be Rotband putty from the famous Knauf company. Plaster is high quality and reliability.

Wall finishing, which is carried out outside, plays a huge role and is considered one of the main stages of work. By clicking on, you will become familiar with the wall façade panels.

The screed is a mandatory component of the structure of any floor, which is located under floor covering, and ensures durability and resistance finishing. You can learn how to properly screed a floor.

In addition to all the drawings, you will find application techniques and even step by step instructions on creation decorative flowers and other geometric shapes that can be visually similar to a high-quality 3D print.

With your own hands

Don't have enough money to buy a ready-made composition in a specialized store? Don’t be discouraged, because armed with some knowledge and skills and applying them in practice, you can make good structural plaster.

• The basis should be a lime-cement mixture. In addition, you cannot do without gypsum or clay. Natural solids are added to this mixture. It can be a crushed shell, stone chips, sand particles, and even special flour;
• if you chose acrylic resin as a base, which is not so easy to use, you should mix it with synthetic granules required sizes or crumbs near a stone;
• Basically, craftsmen mix plaster from a cement-lime or clay composition on their own, all because the necessary components will always be available for purchase.

It is also necessary:

• Surely those who have dealt with repairs know about the existence of M400 cement. Directly he will be most suitable for achieving the intended goal;
• to create plaster for you you can't do without lime. But, remember that you should only purchase slaked or bring it to such a modified composition on your own;
• When choosing sand, focus on river quartz. Consultants often suggest purchasing orange sand, but it contains clay impurities. Before adding a component, it should be sifted, the more times, the better;
• When preparing plaster, you can’t do without water, but don’t rush to run to the bathroom, it’s better to go to the nearest spring and get water from there.

To speed up the process, you can add a little glue or plaster to the composition. If you want to achieve the exact opposite result (for example, when drawing three-dimensional decor), add a few milliliters of detergent to the future mixture.

It is not enough to know what materials are needed; if the sequence and proportions are not followed, a positive result should not be expected. The volume of material is calculated individually. But, nevertheless, it is worth taking the proportion as a basis: 1x3x0.7, where the first number is cement, the second is sand, and the third is lime.

Lime is prepared as follows.

The quicklime mixture is poured into a metal container, filled with water so that the top ball is completely covered, the lid is closed and an additional weight is placed on top.

During the reaction, a large amount of heat is released, which provokes the appearance of numerous vapors. After some time, the resulting mixture should be filtered through layers of gauze and the resulting solution should be left for another 24 hours.

“What should be the ratio of sand and cement?” – the answer is simple: regardless of the area, connect these two elements 1:3.

Surely there will be those craftsmen who are ready to argue and say that it is more rational to take the ratio 1:6 as a basis, but if you apply this knowledge in practice, they demonstrate that in this case you will create low-elastic plaster, which will be very difficult to work with.

After completing all the previous steps, begin introducing decorative particles.

Dry components are poured using lime mortar, which is mixed until smooth. The resulting plaster will remind you of light gray water.

If you've been dreaming of a completely different shade, add a little mineral coloring pigment.

Clearly see

If you want to see what structural plastering options are offered by advanced international companies, be sure to watch several videos that are presented on this channel.

There you will find a detailed discussion of what Rollputz structural plaster is, as well as a video about useful equipment that will be needed during the application of plaster.

You will find information and detailed information about Triora “lamb” structural plaster here:

If you don’t know how to apply structural plaster correctly, this video will help you:

The main thing here is that not only the composition of the purchased material is taken into account, but also the technique of its application; various inaccuracies only make the result more attractive, this is how a unique finish is obtained

Structural plasters have appeared on the sales market for quite some time. It is quite practical and the price is not high, you just need to apply it correctly. After all, this is perhaps the most important thing in this coating.

Today we will look at how decorative structural plaster is applied. You can also see everything clearly in the video in this article.

Structural decorative plaster is divided into three main types:

• Smooth surface, having different color shades.
• Plaster with a certain texture obtained using ready-made stencils.
• , as a result of using arbitrary drawing techniques.

Features and advantages of the material

The basis of structural plaster is made up of polymer or mineral binders, in combination with various fillers in the form of sand, granules, crumbs, synthetic and natural fibers, etc.

Structural facade plaster different in relief, for example, 0.3 mm in size, they create an imitation of sandstone; with the help of grains 1.5 mm in size, you can get the look of untreated stone. The widely known one has a filler with grain sizes of 2 mm, and to achieve the effect of real tree bark, you will need decorative plaster with grains of about 3 mm in size.

Structural plaster application technology can have both a smooth and rough surface. If you plan to have a smooth, structured surface, then you should carefully prepare the base, since this type of plaster will not be able to hide surface defects.

If we compare ordinary plaster with structural plaster, the latter has a number of advantages:

1. It can be applied to all types of surfaces: concrete, brick, wood (see), stone, drywall and metal.
2. It is able to hide all surface defects.
3. Has increased resistance to mechanical damage.
4. Characterized by excellent water-repellent properties. It can be washed using any cleaning chemicals.
5. It can be operated at temperatures from -50°C to -75°C, which expands its application environment.
6. Technical characteristics indicate its high ductility, which allows you to create a surface of any texture.
7. She is able to "breathe", and this makes it possible to create the necessary microclimate inside housing and administrative buildings.
8. Surfaces lined with structural plaster have a long service life.
9. During operation, it can be repainted in any color you like.
10. The composition of structural plaster allows you to create, in principle, any ornament on the plane.

Application of material

Structural decorative plaster can be easily applied with your own hands. Only everything must be done in order and according to technology. To decide on the pattern of the structural surface, you should contact a designer who has the entire range of such surfaces that are stored in the photo, or choose it yourself. Then you will save on this.

After looking at such photos, you can decide which design is more suitable or likes better.

Attention: When choosing structural surfaces, it should be taken into account that they are capable of collecting and retaining dust or excess moisture. Therefore, it is very important that they are not used in the kitchen or bathroom.

Preparatory work

Decorative structural plaster is applied to a properly prepared surface.

It is desirable that the plane be smooth and strong:

• If the surface is not smooth and durable, then everything must be done to make it so. As a rule, such surfaces are possible using a mesh - chain-link.

Attention: If you already have a coating and at first glance it holds well, you should take the ground one and tap it. Anything that does not hold must be removed. And if there are cracks, then we simply crush them with a chisel.

• After this, the plaster must be given time to dry completely, only after which further work can be continued.
• The next mandatory step is priming the surface with a deep-penetrating primer. As a rule, structural plasters are able to hide small irregularities, so very careful preparation not required.

To carry out such work you will need the following tools:

• Trowel, plaster trowel.
• Spatulas of several sizes.
• Plaster float.
• Angle spatula.
• Construction level, plumb line, rule.

Application process

Application of structural plaster video will show you the procedure for applying the material, everything is done as follows:

• First you need to apply the plaster to the surface and distribute it in an even layer over the entire surface, using a trowel for this. At the same time, you should not adhere to ideal uniformity of the layer. The thickness of the layer depends on the pattern, as well as on the size of the filler grains, plus a millimeter and a half of the required margin.
• To understand the meaning of applying this type of plaster, especially for those who have decided to master this technology on their own, you need to practice on a small piece of drywall. As a rule, mastering occurs very quickly, since there is nothing complicated in that technology.
• Ready-made mixtures have the ability to harden slowly, which gives the master time to correct the design. If you use homemade solutions, it is better to decide in advance on the texture of the surface and apply the plaster in small areas.

Adding texture

In order to obtain this or that drawing, they can be used various instruments, such as:

Final stage and decoration

After completing the stage of forming the texture of the plastered surface, you should begin the process of designing and protecting the textured surface. As a rule, one layer is not enough.

• If desired, you can highlight the relief of the design using paints. To do this, the first layer of paint is applied with a long-haired roller. To apply the next layer, use a short-nap roller. In this case, a lighter paint is selected for the second layer.
• If painting is not planned or another type of plaster is used, then such a surface can be protected with several layers of colorless varnish.

You can also use various compositions in your work:

• To create unique drawings, it is possible to use various fillers that are introduced into the main composition of the plaster. As an example, you can take bark beetle plaster, which contains polymer granules or natural stone chips.
• The technology of its application is that such plaster is applied to the entire surface of the wall, leveled in an even layer and allowed to set a little.
• After this, take a grater in your hands and rub it over the surface of the plaster, using various movements for this. At the same time, the granules that are part of the plaster are pulled behind the grater, leaving behind specific grooves.
• Depending on the direction of movement, they can be located vertically, horizontally or have various directions, making the design unique.

At the same time, the use of structural plasters is not limited only to these technologies described above. There are many interesting techniques that allow you to get truly unique drawings.

• Take, for example, the use of multi-colored balls in structural plasters. These granules are made of such a material that when you press on them, they are crushed, leaving behind multi-colored marks. At the same time, the technique of applying such plaster is no different, for example, from the technique of applying “bark beetle”.
• If you use more liquid solutions, you can get a surface with a smudge effect. To obtain patterns that have a clearly defined structure with deep grooves, thicker solutions should be used. At the same time, you should always remember that the deeper the grooves, the more dust will collect in them.
• As a rule, ready-made plaster mixtures are sold in pure white color, which makes it possible to use plasters using various technologies: They can be dyed any color after application or dyes can be added directly to prepared plaster solutions. To get desired shade, it is better to contact specialized stores where they can accurately select the required shade, taking into account the drying of the paint.
• If at this stage it is very difficult to choose a color, then it is better to use painting. In this case, the shade is selected experimentally by adding one or another dye directly to the paint. After this, small marks are made on the plastered wall with freshly prepared paint, and after drying, the color saturation is determined and compared with the intended one. Once the colors begin to match, you can begin painting.

How to make structural plaster video will help you choose the right tool for applying texture. After all, decorative structural plaster is not difficult to apply; it is important to know how to apply the desired relief.

Nowadays, structural plasters are widely used for cladding interior and exterior walls. Why? They are durable and attractive, the technique of working with it is simple and, if desired, structural plaster can be applied with your own hands.

Features of the material

The basis of the material is mineral or polymer binders and various fillers - sand, granules, crumbs, flour, natural and synthetic fibers.

Classification

The surface texture depends on the fractionation of the filler. An imitation of sandstone is created by a grain size of 0.3 mm; the texture of raw stone is obtained using plaster with grains of 1.5 mm. implies the use of filler with a size of at least 2 mm, and if you want to achieve the effect of tree bark, you will need material with a filler size of 3 mm.

Both smooth and rough. Smooth wall cladding needs to be prepared more carefully, since it cannot completely hide surface defects.

The photo shows different textures of plaster

Advantages

Structural plaster cladding has a number of significant advantages over traditional types of coatings.

1. Applied to all types of surfaces: brick, stone, concrete, drywall, wood, metal.
2. Hides surface defects.
3. Has significant resistance to mechanical types damage: impacts, scratches, chips.
4. Waterproof. the walls are easy to clean without losing their appearance and strength. In this case, you can use any means household chemicals, which do not contain a solvent.
5. Withstands temperature changes from -50 °C to +75 °C, this significantly expands the scope of use of this product.
6. Has high rates of plasticity and elasticity. Therefore, textures of any complexity can be recreated on the surfaces of walls, ceilings, and columns.
7. The lining is microporous. Thanks to this, structural plasters breathe, which has a beneficial effect on the microclimate interior spaces buildings.
8. Has a significant service life.
9. Can be freely repainted during cosmetic repairs.

Application technology

A thin layer of coating can be applied with a trowel (price - from 150 rubles)

At the first stage, the surface is cleaned of dirt, potholes and cracks are sealed. There is no need to achieve a completely flat surface; structural plasters mask small flaws well.

Instructions for carrying out work:

Preparing walls for, unlike other types of decorative coatings, does not require puttying the surface. It is important that they are durable, visually smooth and dry.

The cleaned walls are primed. Do not skimp on deep penetration soil, it improves the adhesion of the cladding to the base. For all walls, in addition to wooden ones, regular soil is used. Wood requires a special mineral primer.

To be on the safe side, you can use an additional coat of primer paint. It is applied after the soil has completely dried. The paint will strengthen the butt joints typical of sheet substrates - plasterboard, OSB, chipboard.

Prepare the plaster mixture. Mix the dry mixture with water in the proportion specified by the manufacturer in the instructions. Mix the solution using a construction mixer or a drill with an attachment, let the plaster sit for 10 minutes and mix again.

Start the main work from the ceiling or the top of the walls if the ceiling is not covered with a structural coating.

Apply the first layer of the mixture by spraying. Level it, carefully work out the corners and cornices. After the spray has set, apply a second layer - a covering layer. Flatten it and let it set, but not completely. The third step is to rub the plaster.

In the described sequence, recesses, niches. The cladding is applied to the bottom of the walls last.

If a thin layer of coating is planned, work with a spatula or trowel. The movements should be performed in cross directions, the ridges that protrude from under the tool will form the pattern.

Dry the plastered surfaces for 6-8 hours. It will take 24-48 hours for the coating to completely cure. After this, sand the ridges, remove dust and dirt with a damp sponge.

Important points

In most cases, structural plasters are sold unpainted - white. Color can be imparted to the coating using two methods. Buy a dye (preferably from the same manufacturer as the plasters), add to the mixture and mix well.

The technology also fully allows for painting surfaces after the facing layer has hardened. To obtain color transitions, rub the dye with a rubber sponge. If you want to create the effect of an old coating, you can imitate scuffs with a slightly damp foam sponge. When the painted surfaces are completely dry, they must be treated with protective wax.

Important! Structural plasters are difficult to remove from any type of surface, so you need to seal it with masking tape and plastic film all areas adjacent to the workplace.

Pay close attention to processing external corners. Apply the plaster first on both sides of the corner, then finish it using a corner trowel or by installing an external metal profile.

A slightly set coating can be given a different finish. What is good about structural plaster is that its application technology allows you to achieve a wide variety of effects and textures. You can roll it with rollers with reliefs, smooth it with a notched spatula, create circular and curvilinear patterns using sponges, washcloths, pieces of polyethylene, and brushes.

Summing up

We hope our material was useful to you. All we can do is wish you good luck and invite you to watch the video in this article.

Photo gallery

Structural plaster for interior work has been known for a very long time. It was used as a material for wall decoration several centuries ago. The classification of this type of coating is quite diverse. These are also used for indoor ceilings.

When considering the question of what structural plaster is, you should also take into account the possible need to use a finishing finish such as wallpapering or painting. Different ones may have independent decorative value and do not require final finishing.

Classification of structural plaster by composition

Structural plaster is available in a wide variety on the market today. The most popular are 4 classes, among them:

• silicone;
• mineral;
• silicate;
• polymer.

Mineral ones are also called lime-sand, and polymer ones are called acrylic. The main substance in mineral plaster is cement; this mixture has high vapor permeability and good water absorption. After drying, the mixture is subject to moderate contamination. Inorganic substances are used as pigments.

Mineral-based plaster has low elasticity, but is resistant to ultraviolet rays. It has average microbiological resistance and low abrasion resistance. When considering the advantages, you can take into account that mineral structural plaster is resistant to atmospheric precipitation.

Description of acrylic, silicate and silicone plaster

Structural plaster for interior work can be acrylic, silicate and silicone. In the first variety, the main substance appears in the second and third - liquid glass and silicone resin, respectively. As far as vapor permeability is concerned, acrylic plaster does not allow steam to pass through well, but the other two varieties are excellent.

Water absorption is low, silicate is average, silicone is low. If you do not want to see dirt on the walls, then you should choose silicone plaster; it has a low susceptibility to dirt, like silicate plaster. But acrylic is high. Pigments in latest version can be inorganic and organic, like the silicone version. As for silicate plaster, the pigment will be inorganic. Acrylic or silicone plaster has a high degree of elasticity, while the silicate variety of this decorative material has average elasticity.

Reviews of lime-sand plaster

Lime-sand structural plaster for interior work is often prepared with the addition of gypsum. This variety, according to buyers, is the most environmentally friendly. In terms of wear resistance, the layer will be inferior to competitors.

Buyers choose mineral plaster for finishing walls and ceilings in the bathroom, because such a surface, after drying, is not afraid of moisture. Consumers also like the affordable cost, because the components are based on low price. That is why lime-sand plaster is the most common.

Reviews of polymer and silicone plaster

Polymer structural plaster for interior work has high plasticity, which buyers really like. It is resistant to humidity and aggressive environments, durable and strong. But many consumers do not like the fact that polymer mixtures have limited vapor permeability. As an alternative solution, you can choose a silicone mixture that can be applied to old coatings.

Buyers note that they like this finish due to its resistance to sunlight. Among other things, the walls and ceiling will not attract dust and will begin to exhibit self-cleaning qualities. This is explained by the fact that water and dirt collect in drops and then flow off the non-wetted surface, which is important for rooms with high pollution. Silicone plaster also attracts consumers due to its long service life. It is produced in the form of convenient ready-made mixtures, due to which application does not require any effort on the part of the master. However, silicone compounds are quite expensive, which sometimes limits their distribution.

Reviews of silicate structural plasters

Looking at the review of structural plaster for interior work, you can understand that the silicate variety is resistant to mold and putrefactive formations. Consumers like that the dried layer exhibits water-repellent characteristics.

Among the advantages, it is worth highlighting fire safety and a wide variety of shades and tones. Consumers emphasize that silicate mixtures have phenomenal service life, because durability sometimes reaches 60 years. However, in terms of cost, this type of plaster is one of the most expensive.

Types of structural plasters according to decorative qualities

Structural plaster for interior work, the types of which were described above in terms of composition, is also classified according to its decorative properties. For example, on sale you can find mixtures interspersed with large particles. When applied with a trowel, the elements leave an uneven mark. The most common type of such surface is the “bark beetle”, which imitates wood damaged by insects.

Recreates a surface that imitates natural stone. The surface turns out to be uneven, which is very popular among designers. The most popular type of such coatings is “Graffito” or thin-layer. As a result, it is possible to obtain a surface that conveys the appearance of:

• moire silk fabric;
• porcelain stoneware;
• velvet;
• wood;
• genuine leather.

By using textured plaster you can hide wall defects; there is no need to carry out preparatory work. The main difference is that such structural decorative plaster can be applied to any surface, namely: plastic, wood, brick and concrete.

Description of flock plaster and composition based on marble chips

Structural plaster in interior decoration is used quite often today. This includes flock plaster, which contains natural cellulose, mineral dyes and fillers, as well as silk fibers.
