Imitation of stone with decorative plaster. Do-it-yourself decorative plaster to look like stone Imitation stone putty
IN modern construction many are used finishing materials for decorating the appearance of building walls and other structures.
Still popular classic types finishing with brick, ceramic and granite tiles and natural stone.
The use of solid natural stones for construction is limited to their high cost, inconvenience of use due to their significant weight and lack of great availability.
Therefore, finishing building materials with an imitation of stone structure have now begun to be used. Methods for decorating surfaces a natural stone a lot of.
Among them are wall decoration using.
Modern technologies made it possible to create many types of this finish, similar to various natural materials in texture and color.
So, using this finishing method, you can reliably imitate the look of malachite, marble, granite and other stones.
Decorative economical and effective way external design surfaces of buildings. 
By replacing natural finishing materials with coatings that imitate them, the load on load-bearing walls.
The decorative finishing mixture includes:
- Crushed waste from processing natural stones in the form of stone chips;
- Cement as the main binding filler. In some mixtures, acrylic or its mixture with styrene is used as a binding component;
- Fine lime to give the mixture plasticity;
- Quartz sand as a filling component;
- Mica chips to give the mixture a reflective effect;
- Pigment dyes to give a natural shade when simulating breeds.
Preparation of the composition
Finishing plaster mixture is usually sold dry and is intended for self-made solution.
This type of decorative stone-like plaster is used for finishing the surface, so the preparation of the mixture must be approached with special care. 
The presence of lumps, bubbles, and foreign inclusions is unacceptable. It is better to prepare the mixture in a wide container, convenient for stirring the composition.
Water is poured into it in the volume of a fourth of the amount of dry mixture.
Then the plaster is slowly poured into a container of water and thoroughly mixed with a construction mixer.
You can use a drill with an attachment. After stirring, the mixture is allowed to stand for about ten minutes, and then thoroughly mixed again. 
The finished composition should be used immediately after preparation, so you need to mix the amount of plaster required for a single application.
If you want to apply a deep stone texture, you need to prepare a mixture that has a thick enough consistency so that it does not spread when applying the relief.
We invite you to watch a video on the topic of the article:
The surface on which decorative stone-like plaster is applied acquires the properties of this coating:
- Good tolerance to temperature changes;
- Resistance to ultraviolet rays and color stability for a long time;
- Moisture resistance, promoting protection from climatic precipitation;
- Vapor permeability, resulting in no condensation;
- Resistance to mechanical shocks.
Stone surface imitation technology
Imitation of masonry on a plastered surface is carried out in several ways:
The “Wild Stone” technology involves applying a base to a small amount of surface, then covering it with a finishing coating and imitating a stone surface using a trowel.
After drying, color streaks are applied and rubbed into the surface with a sponge.
The Marmorino technology is based on knocking out rectangular stone boundaries using a chisel on a previously applied and completely dried layer of special plaster mixture.
The formation of the “Ragged Stone” pattern is carried out in a similar way, only the notches are made not along straight lines, but chaotically.
Applying a relief pattern using special forms that replicate the structure of natural stone.
This form with with a little effort apply to the previously applied and not yet set plaster mixture and squeeze out the profile.
They make molds using polyurethane or polymer. They can be in the form of natural stones of different sizes and others.
Stone plaster has a wide range of uses. It is used for:
- External cladding of building facades;
- Coverings of basements and foundations;
- Column finishing;
- Decorative design of fences;
- Finishes interior walls premises, both completely and in fragments in the form of panels;
- For cladding arches, openings, fireplaces, bar counters and other elements of interior decor.
Advantages
Decorative stone coating has many advantages over other finishing materials:
It is lightweight and does not require additional reinforcing devices during application.
Can be used to simulate various facing materials: brick, natural stone, etc.
Can be applied to any surface: brick, concrete, chipboard, plasterboard, foam concrete blocks and others. 
Along with decorative function can perform a leveling role; for this it must be applied in two layers.
Resistant to delamination and cracking due to temperature changes and physical impact.
During operation long time retains its original appearance.
It has a low cost.
Like any building material, decorative plaster, which is used to create an imitation of a stone pattern, is not without some disadvantages. 
These include:
Provoking corrosion metal parts, built into the facing surface, since the plaster is water-based.
Limited use for cladding structures in which mineral slabs are used for insulation, since this affects the vapor permeability of the decorative coating.
If you plan to finish the external walls of a building, it is better to use a mixture whose binder base is cement. 
This plaster composition is most suitable for surfaces exposed to sudden temperature changes and is resistant to humidity.
The thickness of the finishing layer should be no more than 10 mm.

The appearance of the entire house largely depends on the appearance of the basement of the building. The most popular and desired decoration option is natural stone. It is, of course, beautiful, but quite expensive. How you can make a high-quality imitation of stone, thereby saving significantly, is described in this article.
Nothing gives more solidity and solidity appearance buildings like natural stone on the plinth. It would seem that it would be easier, buy required material- natural or artificial, stick it on the concrete or brick base of the plinth and you’re done. However, there are often cases when such an option is simply unacceptable, both from a constructive and financial point of view. It is absolutely clear that ready-made stone slabs are initially quite expensive, and if it is also necessary to prepare a special base for them, for example, if the base is insulated from the outside, then all this will ultimately cost a fairly decent amount. You can save significantly and at the same time get a result that is almost no different both in appearance and in feel from natural stone if you make an imitation of it. We'll talk about how this is done further.
As a role model, let’s take this option for finishing the base with crushed granite slabs:
As a result, if you do everything in accordance with the instructions given, you will get this result:
As you can see, the result is almost identical to the reference one.
Materials and tools
To carry out the work we will need the following materials:
- Plaster mixture - one 25 kg bag per approximately 5 m2. Price - 4 USD e.
- Facade primer - 0.5 kg per 1 m 2 of one layer. A 25 kg bucket costs about 20 USD. e.
- Facade paint - 1 kg. For 1 m 2 one layer. A 25 kg bucket costs about 50 USD. e.
- Decorating paints - base paint plus colors. In total it will cost about 2 USD. e. per 1 m 2.
- Plaster mesh. The thing is quite cheap - about 0.4 cu. e. per 1 m 2.
- The covering film is the thinnest.
Using even initially not cheap quality materials provides savings compared to natural stone at times!
Tools:
- Maklovitsa for primer (not plaster).
- A non-fluffy roller, for example, a felt roller for rolling film and smoothing seams.
- Fluffy paint rollers.
- The brushes are flat and thin.
- Spoon.
- A stiff brush for cleaning baths, to give additional texture to the stones.
- Mixer for dry mixtures.
- Sandpaper.
Making an imitation of stone on the plinth
All work can be divided into three stages:
- preparation of the base;
- production of imitation stones;
- decoration.
So let's get started. We have a base insulated with foam boards. Let's prepare the base.
1. Mix the mixture.
The same mixture, by the way, is also used for false stones.
2. Apply a layer of approximately 3 mm, having previously filled the seams.
3. Cut a strip of façade reinforcing mesh to the required length.
4. Apply the mesh and smooth it with spatulas, hands, whatever, but so that not a single bubble remains. We cut the junctions at the top and bottom to a width of about 1 cm; the mesh should not tuck under.
5. Apply a second layer of the mixture 2-3 mm thick and leave until completely dry.
6. Prime the surface with primer for exterior use, with deep penetration on loose surfaces. We prime the entire base. Leave to dry for at least three hours in dry weather.
7. Mix the same mixture as for the mesh. We apply it to the base coated with primer.
Make the mixture quite dense; it should not flow. Apply a layer up to 3 cm. After drying, apply another layer. As a result, we get 6 cm of final thickness. There’s no need to do a lot at once, just a couple of square meters.
8. While the mixture is wet enough, apply thin film for covering furniture, pre-moistened in water. If the film is not moistened, you risk tearing off the entire mixture.
Wrinkle the film on the surface of the base, as it turns out, and roll it with a fluffy, but not very soft roller - a rope or felt one will do. We skate quite hard.
As a result, we get the following surface:
9. Remove the film moving to the side. We get the texture of natural stone.
The film must be wetted before each gluing.
10. We proceed to the next stage - making false stones. Using the flat end of the brush, apply the jointing pattern. We try not to cut all the way to the ground. Where convenient, we help ourselves with a spoon.
11. We wet the roller that was used to roll the film in water and roll the edges of the seams a little to smooth them out. Next we go through the seams with a wet brush. This will make them neater.
12. To add additional texture, you can prick the surface with a brush. Leave to dry.
13. After drying, knock off debris and burrs with coarse sandpaper,
14. Prime the resulting surface. This should be done crosswise.
15. Apply base paint.
16. We tint the “stone” slabs. A complex process, but quite exciting, not required here certain conditions and artistic skills. To imitate living crushed granite, use red, brick, dark brown, black, and white to lighten.
The colors are mixed directly on the base. We repeat the stained seams with the same base paint.
17. When everything is dry, we add an aging effect and hide imperfections. Take a thin flat brush and get it dirty in a light tone and with the edge or the very tip we touch the surface of the stones. When the paint on the brush runs out, dip it in paint again, hit the end on the cardboard to remove the excess so that there are no mistakes, and apply it to the stones. It is better to repeat one place several times than to overdo it with white.
A close-up view of the surface should look like this:
18. If you want to add gloss to the surface, you can varnish the stone. No varnish is required to fix the paint, modern facade paints durable and last for many years.
19. You can emphasize the seams dark paint. Get a more expressive surface. In the photo, the seams on the left are light, on the right are dark.
20. Upon completion of all work, you will receive almost natural stone on the foam plastic surface of the base insulation.

Stone is one of the oldest materials used by people to build houses. It is durable, has many shapes, colors and allows you to create a reliable structure for centuries. Stone walls create an effect ancient castle, a cozy family hearth.
Build a house from this natural material very difficult and expensive, but achieving a similar effect with the help of decorative stone-like plaster is quite possible. We will introduce you to its types, preparation and application technology in this article.
Stone-like plaster: description, types, composition
The basis of the mixture is powdered natural stone. So that the mass holds its shape and resists impact environment, cement, quartz sand, mica, marble chips, lime, and plasticizers are added to it.
Different types of natural stone coatings differ in the texture of the filler. It can be coarse- or fine-grained, allowing you to create a textured surface, as well as powder-like - to obtain a smooth layer.
Decorative plaster can be used for finishing walls inside and outside the building, basement and facade of the house
Varieties of decorative coatings imitating stone
Thanks to fillers, the plaster looks natural. So plaster " torn stone", after application and hardening, it is susceptible to the action of a chisel or tongue. Using these tools in different places pieces of the mortar are broken off, forming large irregularities.
Please note: when treating the surface to look like “ragged stone” optimal thickness finishing layer - 3-4 cm.
An example of how to make plaster under wild stone forging method
To obtain a surface with a pronounced texture, the plastered wall can be treated with bush hammer. Impacts with the tool are performed until the top film falls off and the filler grains are reached.
An example of how to use bush hammers to give relief to decorative plaster under a stone - in the photo
To create furrows or grooves, the plaster is treated with a Trojan. It can be triangular or rounded, which allows you to create recesses different sizes and shapes. To obtain large or shaped furrows, a scarpel is used.
Scarpel allows you to make vertical, inclined, herringbone and checkerboard recesses on the surface
In order to imitate travertine - Roman stone, decorative plaster is applied in two layers and carefully smoothed with a trowel. After this, the surface of the coating is ruffled and slightly smoothed with the edge of the tool. After 20-30 minutes, the plaster is treated with a trowel using the “ironing” method (a thin fixing layer of cement mortar is applied to the surface).
Decorative plaster “Stone Travertine” looks good in the interior of classical and modern styles
Allows decorative plaster to imitate small stone. It is based on painted marble, quartz, or granite chips. An interesting texture is obtained due to fine-grained stones, which, when processed with a rubber float, create interesting grooves on the surface.
On a note: crumb-based coating resistant to mechanical damage and environmental influences.
The color and texture of decorative chips are achieved through acid etching

Features of applying stone-like plaster
It is not necessary to invite a master to create decorative coating- It’s quite possible to make stone-like plaster with your own hands. To do this, you will need a set of tools and materials for preparing the solution and creating the relief.
Tools for processing decorative coatings
Preparatory stage
Before finishing, you should carefully level the walls - this is the basis for the strength of the future stone covering. The surface is cleaned of chips, large cracks and gouges are sealed. cement-sand mortar, small ones - lime or gypsum.
Attention: The decorative coating is applied to a clean and dry wall.
To improve the adhesion of the decorative mixture to the wall, the surface is pre-primed
The mixture for decorative plaster is prepared from cement, sand and water. The ingredients are mixed in the following proportion: take 4 parts sand for 1 part cement, add water gradually until a homogeneous thick mixture is obtained from which stones can be formed.
Preparation of the solution
The mixture is applied to individual sections of the wall gradually, in equal parts. You should not treat the entire surface at once - the plaster will dry quickly, and you may not have time to give it the desired shape.
Applying the first layer of mixture
You can form irregularities using tools or manually. To do this, wear gloves and dip them in water (this will prevent the mixture from sticking to them). Next, you can start sculpting stones from the mortar applied to the wall.
Plastering the foundation under the stone - forming the relief
When the coating is dry, it should be impregnated with a primer. Then the surface can be painted. For painting, water-based paint is used, or facade paint for exterior work.
Secret: to make the coating look more realistic, the seams between the stones can be painted over dark shade- this will add volume to the drawing.
