When the construction of the house comes to an end, it is the turn of finishing work. This is one of the most important and, at the same time, interesting stages, on which the final result of the entire construction depends.
Today there are hundreds of ways to decorate walls and one of the most beautiful options, by right, can be called decorative plaster, which is distinguished by a wide range of colors, affordable price and practicality. Decorative plaster allows you to create an original unique style and embody any design ideas.
Plastered facade of the house
If you properly prepare decorative plaster and adapt it correctly, you can create a magnificent decor on the walls, nothing not different in appearance from a fresco.
But many reject this building material as a decorative finish, considering it very difficult and time consuming. In fact, this is not at all the case. In this article we will tell you about the advantages, features of this material and dwell on the process of making decorative plaster from ordinary putty with our own hands.
Features of facade plaster
Due to the fact that the material contains modern plasticizers, the plaster is plastic, which allows even a beginner to work with it. It is universal, it can be applied to almost any surface (foam concrete, drywall, brick).
Thanks to the correct application, textured plaster allows you to give a building an expensive and presentable look. Therefore, it is a pleasure to work and create designer masterpieces on the wall using ordinary putty.
It is not difficult to apply plaster
Before rather than moving on to the process of creating decorative plaster from ordinary putty, let's understand these two concepts. In general, it is customary to call plaster a building mixture that is intended for leveling walls. It is also customary to call a putty a building mixture for leveling walls, but, unlike ordinary plaster, we are talking about small errors.
What is the difference between putty and plaster
What is the difference?
The larger the fraction of substances included in the mixture, the stronger and more durable the material itself will be.
Starter plaster with coarse dispersion
In order to understand the scope and performance of various types of plaster and putty, let's take a closer look at the composition and types of these two materials.
There are several types of plaster on the market today, which differ in composition and bonding.
| The composition includes a mixture of quartz chips, marble, lime hydrant, light mineral fillers, plasticizers and Portland cement. The advantages of this material are high strength, moisture resistance, long service life and low price. To decorate the material, pigments or marble chips are often added to the mixture, which allows you to play with the design of the walls.
|In addition to sand and coarse cement, the composition is added acrylic resin, which gives elasticity and high strength. It is quite easy to work with such plaster, it lends itself to leveling, has good water-repellent properties. But there is also a serious drawback. Plaster has a high degree of flammability, so it is not recommended to use it near mineral wool insulation.|
| The main connecting link here is natural silicone, which gives extraordinary plasticity to the material.
Despite the rather high price, silicone plaster has a number of unique qualities (insensitivity to UV rays, plasticity, strength, high adhesion, resistance to mechanical damage and a wide variety of colors). Another plus is the speed of work. The composition contains antiseptic substances, therefore, preliminary priming of the walls before application is not required. The only drawback of this mixture is, perhaps, the complexity of the finish. That is, the walls before application should already be sufficiently well prepared, since the silicone plaster is applied in one layer.
|The main link here is liquid glass, which gives excellent astringent properties.Silicate plaster is characterized by a high rate of fire resistance, so it can be used on almost any surface. It is one of the most durable finishing materials with a service life of over 50 years.|
|One of the most common species, which from plaster differs only in grain size.|
| Can be attributed to very exotic options for building material, which not often found on sale.
The manufacturer uses varnish oil as the basis for the thickener. It is highly resistant to moisture and is excellent for treating walls before painting.
| Epoxy resin is used as a base here, which makes this building material is very versatile to use. It can be applied to concrete, metal, plastic, drywall, wood. Differs in a very high degree of strength and resistance to external factors.
|Latex is great for both external wall treatment and and for indoor use. The base is ordinary latex, which gives the material high elasticity. With such a composition, it is easy to seal all cracks, potholes on the plane. The plaster sets quickly, dries and does not crack.| Plaster
If you decide to choose a regular putty as a facade finish to create an intricate decor, you will have to work hard and practice in applying the finish to get a really high-quality finish.
But the result is worth it.
Decorative plaster is, first of all, a play of textures. And already the second part is played by the color scheme. It is important to understand, when starting work, that it is due to the texture, relief that you will achieve a complex texture on the wall.
Facade plaster for stone
Textured plaster has the following qualities:
The possibilities of decorative plaster are not limited only to the creation of an original texture. You can create intricate patterns and paintings with decorative plaster.
Decorative plaster at home
It is best to use silicone putty mixtures as a base. They are more elastic, allow you to achieve a perfect texture and the required relief, and also have a high resistance to mechanical damage.
Despite the intricacy of the texture, this material is quite easy to clean. Dust and dirt can be easily removed with conventional detergents.
There are two types of decorative plaster for facade works:
It hides all roughness, irregularities and before applying it does not require particularly careful preparation of the walls. Depending on the pigment, composition and structure, textured plaster can perfectly imitate natural stone, marble, wood.
The following options are classified by texture:
Plaster bark beetle
The composition of such a plaster includes large stone grains of the same fraction. In relief, such a pattern resembles a rump;
Before than to start cooking, stock up on convenient tools. This will simplify the work and allow you to quickly prepare the desired consistency.
You will need:
Spongy plaster trowel
Step 1. We carry out preparatory work on the surface. We clean off all paint, varnish and other debris.
Wash the wall thoroughly.
Cleaning the brick facade
Step 2. Prime the surface. This will allow to close all cracks, level the walls as much as possible and stop the absorption of the putty by the wall surface, since the primer has excellent waterproofing properties.
Facade primer will prolong the life of walls and outdoor decoration
Apply an antiseptic and anticorrosive protective layer. If decorative plaster is applied to a surface where there are metal nails, screws, pipes, then a protective layer must first be applied to all these parts. Otherwise, in the future, a rusty stain may appear through the plaster. An antiseptic will protect the surface from the formation of fungus, mold and other microorganisms.
Let the primer and protective layer dry well for at least 12-14 hours. It is very important to wait for this period of time, otherwise, after a short period of time, the plaster will lag behind the surface. If, after the first priming, a layer lag is visible or there is a suspicion of surface flowability, then it is recommended to carry out priming in several layers, each time waiting for complete drying. The average time for polymerization and drying of the mixture is 15 hours, but before starting work, be sure to read the instructions on the package, since depending on the chemical components, the period can be significantly increased.
Important! All finishing works must be carried out at a temperature not lower than + 5 ° C.
Otherwise, the quality of the result and the operational properties of the facade finish will be low.
Step 5. Determine the level of alignment with the building level. Keep in mind that the flatness of the walls should be checked in several positions: horizontally, vertically and diagonally.
Now that the walls can be finished, we are preparing decorative plaster.
You can prepare textured plaster from almost any ordinary putty.
In order to decorate the walls with textured putty, the following materials must be prepared:
Step 1. We take a deep vessel (bucket) and mix in it in equal proportions ordinary putty, water and mortar for sealing the joints.
You can first mix only the bulk ingredients, and then slowly add cold water. This will speed up the mixing process and avoid clumping.
Filling dry components
Step 2. Mix the mixture thoroughly with a construction mixer or an electric drill with a whisk attachment.
If the final version assumes a certain color, then after thorough mixing enter into a finished consistency pigment.
Step 4. Check the texture of the finished material. If you feel that the consistency is too thick and does not allow you to work and create the necessary patterns on the surface, then you can add a little water, but do not overdo it, otherwise the material will roll or drain over the surface for a long time.
The consistency of the solution should be like mashed potatoes
Tip! Prepare just as much of the mixture as you need it soon.
The solution will thicken quickly enough and it will be difficult to work with it.
Take a small amount of the prepared mixture with a spatula and apply a thin layer to the wall surface. The layer thickness should not exceed 2-3 mm. Use a special facade trowel for work and start stretching from the lower right corner.
Base coat application
Wait for a technological pause (10-30 minutes) before proceeding with the relief. The drying time of the base depends on the technical characteristics of the working mixture.
Step 1.We mark the wall .
This is an important point if, say, you are planning to translate a design masterpiece into an idea and do not want to limit yourself to the usual application of textured putty. We mark the area of work with masking tape, and the solution can go onto the paper. When finished, this tape will need to be carefully removed.
Step 2. Take a spatula, pick up a small amount of putty again and apply the mixture to the wall .
It can be applied in several movements, depending on the design idea: scarring, circular movements, horizontal or vertical strokes. If you want to create chaotic strokes on the wall, without a specific pattern or relief, then you can alternate the technique. If your idea involves a certain pattern, then choose movements in one direction.
Applying decorative plaster
After each application of the mixture to the wall, thoroughly clean the trowel or trowel before adding a new portion of the mortar. The rest of the mixture must never be put back into the bucket with plaster.
Important! Practice applying the relief to the drywall sheet first. This will give you the opportunity to "feel" the material and create exactly the drawing that you intended.
With a spatula with a notched edge, you can create a specific pattern, and a special roller with a ready-made pattern can be used to transfer beautiful patterns to the wall. The structure and relief of the wall can be adjusted in the process. If the strokes are too harsh and thick, grab the trowel and lightly touch the wall and walk over the surface.
Style "bark beetle" is performed by translational continuous movements performed in a horizontal or vertical position. The drawing will depend on the movement of your hand and it is better to apply it with a float, it will appear already during the application of the mixture to the wall. But individual strokes can be created with a float, applying to the wall and pressing lightly.
The consistency of the solution should resemble thick sour cream, otherwise the mixture may drain from the wall, disrupting the pattern. After applying one layer with a trowel, the "milk" is removed from the trowel with a spatula, in which there are no pebbles.
If this is not done, the relief of the "bark beetle" will not be pronounced. We hold the tool when applying the solution at an angle of 60 degrees.
The layer thickness will depend on the grain size in the finished mixture. The average drying time is 24-72 hours.
Decorative plaster bark beetle: application method
Advice! If you need to take a break from work, then cover the border of the finished drawing with masking tape, on top of which apply a wet solution.
On returning to work, carefully remove the tape and continue the process. This will avoid visible grooves and transitions on the terrain.
"Pebble" texture is achieved by sharp movements in a clockwise direction. It is very important not to interrupt finishing work, as the hardening of the plaster can give a sharp transition on the wall.

To completely dry the pattern, you need to protect the facade from direct sunlight and wind. For this, it is necessary to install a protective construction screen made of mesh or film.
If the film is firmly pressed against the plaster, very interesting patterns will be obtained
Creating a complex relief using a special roller
With the help of a special roller covered with steel mesh, rubberized or with pores, you can create a unique pattern of any complexity on the surface. You can buy such a tool in a store or get creative and make such a roller yourself by wrapping it with twine or cord. Keep in mind that the more often the rope is wound, the denser the relief structure will be.
All work is carried out with a roller, which is carefully dipped into the putty and then the mixture is applied in a thin layer to the wall. Here you can turn on your imagination and work with a roller in different directions.
Now that the desired pattern on the wall has been created, we proceed to the final stage. Decorative plaster can be painted in any color or varnished.
This process is not complicated, but in order for the result to really delight you for many years, several nuances should be taken into account.
Painting decorative plaster
Textured putty is best painted in 2 colors. This will give the surface more bump and volume.
Methods for painting decorative plaster
If you want to focus on the convex parts of the picture, it is better to paint these places with a dry brush. On the other hand, all the dimples and grooves will emphasize the wet brush method, which will slightly blur the color.
If you decide to paint the textured putty in dark colors, then it is better to choose the wet brush method, which will slightly wash out the pigment. When painting the surface in a light range, apply the paint with a dry brush.
After the staining process has come to the finish, let the paint dry well and open it with varnish. Firstly, it will give a beautiful shade to the paint, fix it and protect it from fading and fading. Use a water-based varnish and apply 2-3 coats, each time until the previous one is completely dry.
