5. Marble plaster is resistant to moisture, UV radiation and temperature extremes. It does not fade in the sun.

6. The material is convenient to use. Surfaces are processed without any special difficulties.

7. It is easy to clean and care for the coating.

8. The presence of special impregnations in the composition of the solution prevents the formation of fungi and mold deposits.

9. Plaster has proven itself in the decoration of exterior surfaces.

- Coverage can not please a low cost.

Types of Marble Plaster

There are two types of mixtures:

• based on marble chips. Granules are small and larger, faceted or spherical.
• the basis is marble flour. Such plaster is called Venetian.

Both species appear in the natural color of the stone or a variety of color shades, while the coloring pigment is introduced into the mixture. Consumption of material per square meter is calculated depending on the size of the fractions of the fillers. For instance:

Where it is appropriate to use marble plaster

Since the constituent elements of the material are completely natural, it can be used for finishing any surfaces. Has a presentable and stylish appearance. It is good at finishing concrete and brick, stone and wood, drywall and chipboard. Great for coating:

• surfaces outside: balconies, columns, various arches, harmoniously decorate the facade of the building and even steps.
• walls inside the house. Although marble plaster for interior work seems quite appropriate, but nevertheless the staircase decorated by it, the corridor and the hall will look elegant. The solution is firmly held on surfaces treated with an aqueous emulsion. Therefore, marble plaster in the interior of the bathroom will also be in place.

Scope of marble plaster

Marble plaster is a product that can be used both outside and inside buildings. It can be applied to the ceiling.

Marble plaster mix is ​​in demand in the construction industry and is often used to equip offices, non-residential and warehouse premises. Industrial buildings, shops, cafes, gas stations and so on.

Composition and characteristics of marble plaster

Marble decorative plaster consists of several gradients. The main component is marble chips. To improve the performance, to reduce the cost of the mixture, add granular granite.

Mineral additives or acrylic-based resins are added to the composition of the product as binders. Not often, but nevertheless, they use active substances to combat pathogenic bacteria, fungus and mold.

Also, you can use certain components to protect the coating from the harmful effects of ultraviolet radiation, active chemicals and so on. Mother of pearl, which is added to the product, works as a decorative element.

Types of material

Marble plaster for interior use includes binders, which are divided into types:

1. Lime.
2. Composition on acrylic basis.
3. Sand and cement.

As for outdoor work, for the most part, acrylic resins are used in the processing of facades. In retail, you can buy marble plaster based on gypsum, meaning dry mix. Although the product is expensive, it is in demand when decorating small or especially complex areas.

It is important to choose the material and correctly determine the size of the fractions of marble. It could be:

Fine grain composite 0.2-1 mm.

The average grain is 1-3 mm.

Coarse grain 3-5 mm.

There are two types of marble mixes on sale:

1. Dry products that mix together.
2. An option requiring only the addition of water.

In any case, buying them you need to know how to proceed. The algorithm and proportions are indicated by the manufacturer on the back of the package. Here, the deadline for the sale of dry marble plaster is prescribed.

The color scheme of the marble mixture

Marble plaster today is a riot of colors and all kinds of colors. Recently, the range was limited to natural tones of marble. What has changed? Everything is simple. Various colorants began to be added to the dry composition. This allowed us to diversify the shades of marble plaster and offer new color combinations.

On a note. Today's marble mixtures with the addition of coloring components can preserve the naturalness of the paint for 15 years when used on the facade. On internal surfaces, color has not changed for 25 years.

Necessary tools

When applying marble plaster, in addition to the mixture itself, you will need a certain set of tools, including:

1. Two types of spatulas: wide and narrow. It is recommended to purchase one rubber, and the second, made of stainless steel.
2. One and a half, grater.
3. Trowel.
4. Set of sanding paper: for work by hand and under the grinder.
5. Plastic container for mixing components.
6. Drill electric principle of operation and nozzle-mixer. It is needed to work with the dry mixture.
7. Stepladder.
8. Building level or plumb.
9. Master OK.

In addition, primer and putty.

Also, when processing a large area, you will need a machine for applying the finished marble mortar.

It is necessary to work in special clothing, using personal protective equipment. When working indoors, you can do without outside help. When processing the facade, it is better to use a pair of assistants.

The technology of applying marble plaster

Marble plastering involves a series of sequential actions that can be divided into stages:

1. Preparatory work.
2. The process of applying plaster.
3. Processing, smoothing.
4. Finishing work.

In addition, in the interior, hand marble plastering is most often used. Works on the facade differ in volume, therefore, the external parts of buildings are often processed mechanically using special devices. How marble plaster is applied in the interior and the algorithm for processing the facade we will disclose below.

Preparatory stage

Preparation includes cleaning the walls of dust and dirt. We work with a brush and carefully inspect the surface. Having discovered crumbling areas and defects, it is necessary to clean them to the base. We work with a metal brush. You can use a grinder with a nozzle.

Thoroughly clean masonry seams. It is in these places that voids form.

If there is fungus and / or mold on the surface, it must be removed and the affected area thoroughly cleaned. Be sure to treat with a chlorine-containing or antiseptic composition. The efflorescences are treated with a special cleaner, which can be bought at a hardware store.

To get rid of chips and protruding parts, use a cement mortar in the proportion ¾: cement - sand.

For high-quality preparation of walls, cracks should be widened before sealing. Again, remove the dust and clean the dirt. Remember to use fiberglass reinforcing tape.

We work as a rule or level: we check the plane of the working surface. If necessary, problem areas are leveled with plaster. After application, the plaster should dry. Only after that process with soil.

Manual plastering

Manually applying marble plaster requires preliminary preparation of the mixture itself. Since the mixture is thick, it must be diluted. To do this, just add water or solvent. The manufacturer indicates the proportions: look for information on the outside of the package.

The algorithm of actions is as follows:

1. The capacity opens.
2. Dry plaster mixes. We work with a mixer.
3. If necessary, a certain portion of water is added.
4. A small amount of the finished solution is taken on the trowel, which must be kept at an angle of 60 0.
5. The mixture is applied to the work surface in an even layer in one direction. In this case, a little effort is applied.
6. Then the applied mixture should dry. For this, 20-30 minutes are enough.
7. When the material begins to set, it is rubbed with a special tool - grout. We work with a grater made of stainless steel, pressing the tool to the working surface. Processing (grouting) is performed in circular motions with the same pressure force.
8. Again, it takes time to dry the plaster, now the final one.

And only after that, you can work with acrylic varnish. Often, instead of it, a water repellent is used.

Mechanical application of marble plaster

To speed up the workflow and cope with a large amount of wall treatment, it is possible and advisable to use the mechanical method of applying the finished mixture.

The pneumatic crumb thrower is ideal for decoration. As can be seen in the figure, this is a small-sized tank with a nozzle located at the bottom of the structure. The working parts include a nozzle and a special nozzle that aggregates with the compressor. The diameter of the hole of the feed solution should be within 4-6 millimeters.

Plaster is applied to the prepared surface, after scooping up the solution in the working tank and pumping air into the compressor. It is necessary to monitor the pressure. It should be in the range of 6-7 atmospheres. When applying the solution, the bucket should move smoothly, without sudden movements from top to bottom. The distance to the wall within 250-450 mm. the consumption of the finished mixture is 1.2-1.5 kg / m 2. It is necessary to control the process, monitor the uniformity of the wall coating with the working mixture.

After applying the solution, approximately 30 minutes, the surface is grouted. We work with a metal trowel. When the plaster is completely dry, it is coated with a protective compound.

Create a drawing

Wall decoration involves the use of not only one color. Often they work simultaneously in two or three colors, thus creating curly inserts, ornaments or stripes. As you understand, the technology is different from the simple application of marble plaster. To create a drawing, you must first prepare a sketch of the facade, as well as stock up on:

1. Masking tape.
2. Level.
3. Ruler.
4. Felt-tip pen or pencil.

A preliminary marking is carried out, all contours are determined. Priority work sites are noted. Adhesive tape is glued along their contour. Next, decorative marble plaster of the selected color is applied to the working surface. It is important not to go beyond the boundaries of the tape.

After grouting the material, the adhesive tape is removed, as shown in the figure.

Proceed to the processing of the next section. Thus, it is possible to make inserts of the same or different sizes. It all depends on your fantasies. In this process, the right choice of colors: the combination of colors comes first.

How to prepare a grout for stucco

In retail, you can buy ready-made dry mixes: facade plasters with marble chips. However, some masters prefer to make marbled stucco with their own hands, using the following components:

1. Slaked lime or cement-sand mixture 1.89 ml.
2. Marble flour or granite chips 1.89 ml.
3. Liquid soap 30 ml.
4. Flaxseed oil 360 ml.
5. Water 180 ml.
6. Coloring pigment.

Production involves a number of sequential actions:

1. At the initial stage, the dry mixes are mixed.
2. Poured with water.
3. Re-mixed. It is important to obtain a uniform viscous mass.

As you can see, to get marble plaster you do not need to be seven spans in the forehead. The process is simple and straightforward, anyone can handle it.

on the procedure for extinguishing lime in lumps, which we wrote about in detail in a previous article. Use personal protective equipment. Work in gloves, respirator.

Material quantity calculation

To find out how much decorative marble plaster is needed, it is important to determine the working area. When purchasing a dry product, refer to the manufacturer's instructions. It indicates what area can be covered with prepared marble mortar.

We only say one thing: you do not need to buy back-to-back mixtures. It is important to leave in reserve 7-10% of the mixture of the total volume. The fact is that part of the material remains on the working tools. Part on the walls of the tanks.

Plaster composition

The composition of the material includes marble or granite chips, slaked lime, special binders and mineral pigment. The creation of a particularly durable coating is possible with the help of a plaster mixture, in the composition of which granite chips are present. If the composition of the plaster mixture contains two such important components as granite and marble, then a practical high-quality granite plaster is obtained.

It is advisable to use such a composition of granite-marble plaster to create the outer basement of the facade or in places of high traffic, for example, in underground passages.

DIY marble plaster

The finished mixture is sold in any construction stores, but this does not mean that you can’t prepare the mixture for marble plaster with your own hands.Moreover, the price of the finished stucco mixture based on marble chips is quite high, it makes sense to make the mixture yourself.

To do this, you need an acrylic putty and two types of coloring pigment, as well as construction equipment: buckets of plastic and a drill for mixing with a whisk.

First, the acrylic filler is thoroughly mixed with a mixer until smooth. The resulting mixture is divided into two parts and to each add a certain portion of the pigment separately dark and light colors. As a result, the composition of the plaster should be obtained, which will adhere well to the wall and at the same time not to drain from the surface.

There is another more complicated recipe for how to make a composition for marble plaster with your own hands. You can prepare a version of the mixture based on the following components: marble chips and slaked lime in an amount of 1100 ml, soap base 30 g, flaxseed oil with a volume of 360 ml, water 180 ml and mineral pigment.

The technique of applying home-made marbled plaster

DIY marbled stucco is not fiction at all. The main thing is to decide and carefully study the application technique:

First step. The prepared mixture is drawn onto a spatula and applied in small, fine strokes to a selected section of the wall, starting from the top corner. Smears should not have gaps and are applied with a spatula in different directions. Upon completion, the layer of the mixture should dry.

The second step is to sand the first layer with sanding paper. Sanding dust should be carefully removed with a soft brush. Next, you need to create an imitation of natural stone. For this purpose, a dark putty is needed, which is applied with a spatula at an angle of about 30 degrees to the wall surface and is spread in different directions. Random strokes create the desired marble effect. After this, the layer of the mixture should dry well.

The third step begins with the application of a third thin layer with a mixture of white. The layer is applied very thinly, so that the dark mixture is noticeably visible. After drying, the surface of the third layer is ground and smoothed with a metal spatula.

Upon completion, the surface of the plaster is coated with a protective coating.

Second phase

Marble chips are applied on a completely dry, even surface. The coating of decorative plaster is done in the following order: Using a stainless steel spatula, with a metal trowel, apply the plaster mixture with sharp strokes and smoothly level it.

Half an hour after application, the mixture dries out a little and then the surface is rubbed to a smoothness with a polyurethane plastic grater. To facilitate the grouting process, the plastic grater is periodically wetted with water. If necessary, the surface of the plaster layer is also ground.

The plaster layer is dried for two days. It should be noted that high-quality application of decorative plaster is possible at a temperature of at least +5 degrees. If the temperature value indoors or outdoors is lower, then shrinkage cracks may appear on the surface of the plaster.

After the plaster dries, the next layer is applied, repeating all the operations. For high-quality coating, it is recommended to apply up to 7 layers of the plaster layer.

After the final drying of all layers, you can proceed to the final process.

If marble plastering is performed correctly, an optical imitation of marble is created..

Third stage

The essence of the final stage is to create a protective coating of the finished marble plaster with wax, which creates the effect of glossy silkiness. Ancient Roman craftsmen used real beeswax for these purposes, and nowadays, synthetic wax is used, which when applied gives a matte finish.

If desired, nacre or sparkles are added to the marble plaster. As a protective coating, you can apply acrylic varnish, applied in several layers. This treatment repels dust well and creates a waterproof coating.

What is it

Finishing surfaces of the internal premises of buildings and facades produce various materials. The stucco finish with marble is a durable, nice looking coating that reliably protects the building structures on which it is applied. To create it, a mortar is used, which after hardening can last up to 20 years, washed with a brush, will not be covered by damp mold. It will delight the beauty of the natural stone inherent in nature tones. The decorative coating is endowed with such qualities by the flour or small grains of marble present in its composition. Marble plaster classification refers to the mineral type of finishes.

Types and composition of stucco with marble

Marble processing wastes are used as filler for stucco mortar: flour (Venetian or Venetian plaster) or calibrated chips (in some cases, with the addition of granite grains or stone of another breed). The coating, often called by common words - decorative marble plaster, depending on the composition of stone inclusions, there are two types:

• Marble, in which of the fillers only marble chips are used,
• Mosaic, in which the filler, in addition to marble, is represented by granite (granite-marble or just granite plaster for indoor / outdoor use), malachite, quartz, lapis lazuli, as well as other rocks.

The fine-grained stone filler may have a spherical (rounded) or angular (crushed) shape. So that the solution can be applied in an even layer of the same thickness, the stone grains are fractionated. Therefore, according to the size of stone grains, finishing mixtures differ:

• fine-grained - with a granulate of 0.2-1.0 mm,
• medium-grained - granules 1-3 mm,
• coarse-grained - marble plaster for outdoor work with grains of 3-5 mm.

The texture of the surface depends on the grain size. The finer the filler, the smoother the surfaces are, the finer, more detailed drawing can be done. Therefore, coarse-grained mixtures are used for exterior finishing works, fine-grained and containing flour - for interior decoration.

In addition to the stone filler, the plaster mass contains binders, fastening the stone particles to each other, with a plastered surface:

• slaked lime, used since ancient Roman times,
• mineral binders (cement),
• acrylic latex water-soluble emulsion increases adhesion to concrete surfaces (polymers of acrylic resin, which in its pure form, hardens, turns into plexiglass, gives frost resistance, some elasticity, as a result of which microcracks do not appear, the durability of the plaster coating increases).

Of the other components of the stucco mixture can be distinguished:

• water repellent additives
• substances with antiseptic effect,
• preservatives
• mineral and artificial coloring pigments
• components from which marble plaster in the interior acquires additional decorativeness, for example, mother of pearl, sequins, etc.

DIY Marble Plaster

Recipes for making decorative mass for DIY decoration:

• filler: 1.89 l. - marble chips / flour,
• binder: 1.89 l of sand-cement mixture or slaked lime,
• color: pigment of the desired color,
• plasticizer: 360 ml of linseed oil + 30 ml of soap,
• 180 ml of water.

• filler 3 hours - crumbs and / or flour,
• astringent 1 hour - slaked lime (vnutryanka), white cement M400 and higher (for facades),
• water.

Obtaining a homogeneous mass in the presence of a drill with a nozzle is not difficult.

The advantages and disadvantages of finishing with the inclusion of marble

The qualities and properties of mixtures determine their components. The advantages and disadvantages of stucco compositions depend on the type and proportions of the composition.

The following positive qualities can be noted:

• durability,
• wear resistance
• not susceptible to fungus, rot, mold,
• strength (the most durable with the addition of granite chips),
• resistance to precipitation (also used in damp areas, for example, in the bathroom),
• resistance to aggressive atmospheric substances,
• vapor permeability (no condensation accumulates on the walls),
• withstands large fluctuations in temperature,
• immunity to ultraviolet (does not fade and does not collapse, no need to paint),
• non-toxicity
• easy application (due to which it is suitable for finishing surfaces of various configurations - columns, figured ledges, niches, etc.),
• universality (fits well, holds on surfaces of various materials: drywall, concrete, brick, etc.),
• practicality (easy to repair, clean)
• incombustibility
• hiding power (helps hide surface irregularities)
• variety of ready mixes,

Disadvantages:

• vulnerability to certain acids,
• greater specific gravity of the coating associated with the presence of stone components,
• plastering is carried out only at temperatures from +5 to + 35 ° C,
• the possibility of plastering the facades only after shrinkage of the building,
• not one of the cheapest (refers more to finished formulations).

Wall preparation

Before applying marble plaster, the surface on which it is applied is properly prepared. A surface that has slight defects before applying the decorative mortar with crumbs can not be leveled. An ideal surface is needed only for the Venetian. Existing unevennesses are puttied or removed with a grater.

The walls are dried and primed (for better adhesion). Metal parts must be cleaned of rust. If solutions with copper sulfate or drying oil were previously applied to the wall, it is coated with PF-115 enamel to neutralize it. To achieve a better decorative effect, as well as to prevent stains from appearing, the surface is painted with a composition with a tone close to the color of the decorative coating (second primer). After applying each preparatory layer, it is necessary to dry it qualitatively.

The technology of applying the solution with marble chips

In order to finish the mortar smoothly and firmly, plastering is carried out at a temperature of +5 - + 30 ° C. And if, for example, mosaic marble plaster for the facade is applied, it is better not to work under the scorching sun. Also, facades do not plaster during rain.

If ready-made mixtures are used (packed in plastic bags), then they are poured before use for mixing into a container, water is added to them in the amount indicated on the package (for packaging 15 kg - up to 1 l). Stir thoroughly using an electric drill with a nozzle. The main thing is that there is no free water left.

Since the mixtures, when dried, lose moisture and shrink (the layer becomes thinner), it is not recommended to take a break in applying one layer. In one day, without long breaks, it is necessary to cover the entire plastered surface, doing this from angle to angle in horizontal rows (row after row). Then the time interval between the application of the rows will be small. Otherwise, after drying, all joints formed during the break will clearly stand out. If the cultivated area is so large that you cannot cope with it in one working day, then its space is limited by masking tape.

Overlay coating

Applying marble plaster is a simple process. The stucco mortar is drawn onto the trowel with a spatula in small portions. Then, with pressure, it is applied to the plastered surface with a thin layer (thickness from 1 to 2 sizes of stone particles). The trowel is first held at a slope to the wall of 15 degrees with a decrease in the angle until the solution is completely transferred from the trowel. The small part of the mixture remaining on the trowel is thrown back into the tank, since the remainder is thinner. After several cycles (3-4) of applying the mixture to the wall, the trowel is cleaned of its residues with a damp rag so that the drying lumps do not lift up the stacked layer.

Begin to apply a layer from the bottom edge of the wall to be coated (from corner to corner). After applying the layer after a short (15-30 minutes), the period of time is overwritten, correcting and smoothing, for which they use a steel grater moistened with water. After application is complete, the layer is dried for at least 24 hours.

To improve the performance, the finishes with stone chips in rooms with high traffic, corridors, as well as the basement of the facades can be varnished. Such a decorative coating can be washed with a brush using detergents. Varnish is applied by roller. The processed surface dries 24 hours.

Briefly, the technology is as follows:

• the base (wall, facade) is prepared, if necessary, defects are corrected,
• a base coat is applied,
• soil coating is dried for a day,
• if necessary, primer is applied with a color similar to the color of the decorative coating,
• a layer of decorative mortar with stone granules is applied,
• after 15-30 minutes it is smoothed and rubbed,
• dries 24 hours
• a protective varnish or wax coating is applied by roller,
• daily drying.

Application on the facade

Street conditions differ from indoor conditions in several ways. Facades are exposed to large temperature differences, precipitation (including aggressive), and sun. More likely to impact. Therefore, for exterior decoration, special facade plaster with marble chips is used.

It is recommended to start plastering the facades in dry, warm time. The facade material to be coated should have a moisture content of not more than 5%. The technology for performing outdoor work is similar to that described above. Is it possible to do everything as in internal work? No, because it has its own nuances.

1. For external decoration, mainly coarse-grained mixtures are used. Their specific gravity is greater, therefore, the quality of processing of facade walls and compliance with all conditions ensuring high adhesion is a special requirement.
2. The mortar protruding from the joints is knocked down on the brickwork, and the brickwork itself is plastered and dried.
3. The primer is applied at least 2-3 layers with drying of each layer. To do this, use a deeply penetrating acrylic primer. Cover it with a brush or roller.
4. Facade marble or mosaic plaster should be stocked in such a volume that it is enough to finish at least one wall as a whole (from corner to corner).
5. It is also necessary that there is enough time for its application. Therefore, if possible, it is better to work together. One person will apply the coating, the other will overwrite it.

Work can be done manually or mechanically. For mechanical application, a pneumatic crusher is used. For spraying, the nozzle is placed half a meter from the wall and lead from top to bottom. After throwing the solution, it is wiped, not allowing to seize.

Having dried the finish, it is wiped clean with a steel grater. Then apply a protective varnish coating. Varnish is selected from those for external use.

Drawing decorative material indoors

In rooms, plaster is used for interior wall decoration. As a rule, this is a fine-grained mixture. The use of a coarse-grained mixture visually aggravates the room, therefore, if it is used, it is only in limited small areas for emphasis. The same applies to such interior wall decoration as decorative bark beetle plaster. The decorative layer should be thin, because they tend to make its thickness no more than 1-1.5 the size of marble chips. If the area of ​​the processed wall is large, then a crusher can be used.

Marble plaster for interior use has a composition slightly different from the composition designed for harsh weather conditions (by the way, it can also be used inside the building). The main difference in the binder component. For facades, a composition with an acrylic binder is used. Compositions with any binder are well suited for covering the walls of a room.

The room should not have cement or lime based on excessive moisture, so it is better to work when it does not rain outside. The direct rays of the sun should not lie on the wall. All electrical appliances mounted in the wall must be turned off until the finish is completely dry. It is recommended to replace the varnish with wax, because when it dries, it releases unsafe substances that are long weathering.

Create a stone drawing

To make the design more attractive, decorative plaster marble chips are used, which are different in color. In the application of decorative elements with straight lines, there is nothing complicated. Masking tape is used so that the two compositions, superimposed next to each other with different colors, do not mix with each other. You will also need a rake of the right length and a pencil for work. If you need a drawing of more complex shapes, use patterns.

First, a drawing is thought out. Then, with the help of a staff and a pencil, he is transferred to the surface of the wall. The site, which is filled with a plaster composition of the same color, is glued around the perimeter with a masking tape tape. Then, the first composition is superimposed on the site. At the same time, you should try not to “paint over” the areas behind the tape by accident. Adhesive tape is carefully removed after 15-20 minutes.

A day later, on the edge of the dried composition laid on the eve, the adhesive tape is also glued. It will help to avoid contamination of the border area with a composition of a different color, which is applied in the neighboring area. The tape is also removed.

Estimated Consumption

The manufacturer on the packaging gives the consumption rate. In practice, the flow rate is more or less. This, first of all, depends on the skill of the plasterer. Decorative plaster masses with rounded grains are more plastic and stack more economically. Fine-grained mixtures per 1 square meter require less than medium- and coarse-grained ones. An online calculator will help you more accurately calculate the consumption of decorative plaster.

Approximate consumption (limits for different manufacturers are indicated):

• mixtures having coarse fractions up to 8 kg / m2,
• with grain of medium fraction - 4-5 kg ​​/ m2,
• fine-grained mixtures - 2-3 kg / m2,
• with a grain size of 0.5-1 mm - 1-2.5 kg / m2.

Conclusion

Marble-based decorative stucco – beautiful, environmentally friendly material with excellent performance and protective qualities, which is easy to make and apply with your own hands.

Marble and its imitations

Natural marble has a fairly wide palette. There are more than 40 of its shades, and they depend on impurities in the rock of certain substances.

It can be various forms of iron: silicates, sulfides, oxides, each of which provides its own color (greenish, black-blue or red). Different concentrations of graphite give variations of gray and blue gamma.

This stone does not have only saturated green and blue shades:

• In addition, the marble body has beautiful veins resulting from the crystallization of carbon compounds in microcracks. It is their imitation that presents the greatest difficulty when performing marble plastering, and to do it yourself, without having the skill, is not so easy.

Variations of marble plasters

There are several technologies with which you can recreate the texture of a stone of any shade. All of them consist of several rather labor-intensive operations and take a lot of time. But for the sake of beauty, you always have to sacrifice something.

Styling marble plaster

What you need to do first of all is to decide on the color of the marble that you would like to imitate. You don’t have to invent anything: just consider a photo of a real stone and choose the model that you like best as the basis.

• To recreate it, it is necessary to distinguish three dominant colors in the original. The main should be only one, and the other two will be used as additional ones. As a rule, they come from the same color scheme and differ only in tones. If you want to get dark marble, then the most saturated color should be the base. To create light marble, everything is done exactly the opposite.

Marble Plasterboard

• Before applying decorative marble plaster, the surface of the walls must be properly leveled, and the screed should be well hardened. It is not necessary to plaster them: it is also possible to sheathe them with drywall, having previously putty the joints between the sheets (see How to putty the joints of drywall according to the technology). We will not go into these details now, as we will talk about the technique of execution and fixing on the surface of the picture.

Attention: Imitation of marble can be done both with the help of decorative paint, and by using plasters with the corresponding effect. For independent work, it is easier for an unprofessional person to use paints.

Factory prefabricated compounds

When working with plaster compositions, everything happens the same way. The difference is that the paint is applied with a roller or brush, and the plaster, since it has a thicker consistency, with a spatula.

The degree of surface preparation can also be different. Under the paint, it should definitely be well aligned and sanded.

• When using plaster, minor surface defects can be hidden in the process of decorating it. It is even applied to an old screed, if only it is well kept. In this case, it is important to use the correct primer (see. Types of construction primers and their scope). Typically, plaster manufacturers offer special insulating fixers that play this role and are applied to the surface in front of the base layer of plaster.

Basic composition for applying Venetian plaster

• It does not make sense to describe this technology, it’s much easier to watch the video “decorative stucco marble with your own hands” and look for exactly the option where the master works with the same composition that you acquired. The fact is that each manufacturer of plasters has their own recommendations on this subject, and they should be followed in work.
• Using a factory-made compound is much easier, but for most people it is expensive. Marble plasters are purchased in the kit: as a rule, these are: basic composition - 25 kg packaging costs an average of 7500-8000 rubles. Its consumption is 630-650 g / m2, which is enough for about 40 m2.
• In addition, two finishing teams are also included. One with the same weight, but higher price (about 10,800 rubles), the second weighing 5 kg, costing 2,400–2500 rubles. Of course, there are smaller packages - they are cheaper, but in terms of the square of the decorated surface, the price will be the same.

Stucco with marble effect in the bedroom interior

• Thanks to the finest grinding marble flour, which is part of the Venetian plasters, the decorated surface is molded with mother-of-pearl and this splendor looks simply gorgeous in the interior. Such a high cost of plasters due to the complexity of manufacturing the material.
• Lime, which is the main astringent, is aged for a long time in underground bunkers. This is necessary to achieve a certain degree of plasticity and saturation with microelements.

Attention: In addition, in modern plasters there are also polymer resins, which ensure the resistance of the coating to external influences and its service life. This is what allows them to be applied to almost any surface, with the smallest number and thickness of layers.

Glossy marble

There is another interesting technology that cannot be ignored - an imitation of polished marble, which is called “ironing”. This term appeared due to the fact that gloss coated with emulsion lime plaster is induced with the help of hot irons (special, not domestic).

• This type of finish can equally well be called both marble plaster and artificial marble. At the same time, factory compositions are not used: a glossy coating is created according to a special technology with the use of mineral binders and fillers. Moreover, this technology can be used not only to imitate marble, but also any other stone.

• Masters in this case can work both on a stencil and create an author’s composition. In general, the surface finish with iron marble is as follows. At first, this is similar to conventional plastering: the surface is primed, beacons are installed, the base layer of lime mortar is applied and smoothed.
• Powder and marble chips are added only to the topcoats, and they are tinted by adding the appropriate pigments to the compositions, by analogy with emulsion paints. And, by the way, each master uses his own recipe. For example, some of them work only on lime-marble solutions, without the use of mastics for polishing.

Glossy plaster with marble effect

• Other experts apply a soap emulsion to the hardened plaster, and then polish the steel with a polished sole. In the third case, lime soap is introduced into the composition for applying the coating layer, after which the layer is smoothed and covered with wax mastic. After two nakryvochnyh layers with the help of colored emulsions, a drawing is performed.
• This is done in the same way as the drawing technology mentioned above. The result is a similar effect. The only significant difference in the technique of ironing a decorative surface with an iron is the gloss inherent in polished marble. This method of decoration is most often used for decoration of columns, ceilings, individual fragments of walls.

If you are interested in this method, you can watch a master class from professionals. And we will further tell how one more option so beloved by many is carried out: coarse marble stucco.

Stucco with marble chips

The option of plastering, when not marble, but natural marble serves as a decorative layer, has been used for a long time and mainly for the decoration of facades. If in Venetian plasters powder and fine marble sand are used, then in this case it is a crumb of stone with a larger fraction.

• It is introduced into the solution as a filler, and the structure of the coating layer is granular. Decorative effects can be different and depend on the amount and fraction of the filler. A plain or multicolor surface is determined by the color of the stone. We will talk further about how to apply plaster with marble chips.

The advantage of this type of plaster is that it is not necessary, although it can be tinted, and the surface is durable. After all, marble does not fade in the sun, does not absorb water. This is ideal not only for exterior walls, but for interiors of public buildings: covered markets, lobby halls of office centers, train stations, etc. Although, now such a plaster is not uncommon in the home interior.

Primer for marble plaster

Plastering traditionally begins with leveling the walls when necessary, or cleaning the surface of dust and dirt if it is relatively even. Minor roughness under the layer of structural plaster will be invisible.

Before applying it, the wall must be primed. The primer should be quartz, and manufacturers usually offer it as a kit.

• It may be necessary to apply two types of soil compositions: first, ordinary acrylic soil, and then quartz, it depends on how much the porous surface will be plastered. For example, concrete or brick always has to be primed additionally. As for the quartz primer, it does not so much play the role of impregnation, but rather should provide maximum adhesion to a sufficiently heavy filler.

In addition, the primer proposed by the manufacturer also tones the base surface in the desired shade. If the wall is very different in color from marble chips, it looks ugly.

The buyer is offered quartz soil in a white version and the desired color is selected for it. After tinting, a composition is obtained that is very similar in appearance to emulsion paint.

Applying crumbs

This type of plaster is available both in finished and in dry form - when water is added before application. We will tell you briefly about how the plastering process is carried out, but if you need more detailed information, see the “plaster marble crumb video”.

There are always some good videos, watching them will help you do the job yourself much better.

• So, according to the manufacturer's instructions, knead the solution. The volume must be such that it can be quickly developed. If the mixture is ready for use, then it must also be stirred, as the crumbs settles to the bottom. The application of the stucco mixture is carried out traditionally using a spatula with a wide canvas.

Colored marble chips

• Due to the polymer binder, the solution is quite flexible. It is applied and smoothed much easier than, for example, gypsum putty. The main thing is not to take too much mixture on the spatula and to spread the material on the surface with a certain effort. The thickness of the screed should not exceed the size of the filler fraction. Practice first in a place that is not in sight, or use a piece of drywall for this purpose.

20 minutes after applying the layer, you need to smooth it with a grater. The tool is held at an angle, slightly pressing to the surface, and lead in one direction.

As a result, each pebble will fall into its niche, the surface will become smooth, but the color will appear fully after it dries. In conclusion, the screed is covered with a protective varnish, which must be purchased with plaster.
