Finishing home decorative plaster. Finishing technology of the facade of the private house with a silicate brick and other materials
In the process of finishing country houses, special facade plaster is becoming increasingly used.
This is a universal material that is ideal for decoration of residential buildings, garage, laundry and different fares.
The versatility is also based on the fact that the plaster can be applied to a variety of surfaces - plasterboard, concrete, silicate brick, cement and.
Brick, stone, block and other masonry
Give the acid to act well, then rinse thoroughly clean water. Remove all foreign objects and burrs. Remove salt, dust and sand with brush or rigid brush. When the asbestos cement leaf is used outside, cover both sides of the sheets to prevent water absorption, which activates alkalinity and can cause flowering.
Concrete must be cured at least 28 days and be dry before the start of surface preparation. Fill out emptiness, cracks, honeycombs or other visible defects cement mortar And let's harden. It is important to check whether there is a high humidity that migrates through concrete, which can cause the problems of take-off, and the results allow us to make a reasonable choice of paint type for use. To do this, attach plastic films using a camouflage tape to the checked areas. After the required time, check the humidity. If there is no moisture, apply one of the alkyd or latex paints. If humidity is present, latex paint or false floor with a steam cutter can be applied. Allow the acid to act until the bubbles stop on the surface of the concrete.
- Surface dust should be removed with a brush or rigid brush.
- Moisture test: Test of surface moisture in 4 or 5 places.
- Firmly rinse the surface with clean water before it dry.
- Repeat the process until the concrete becomes rude.
- Rinse thoroughly with clean water.
The most important thing is that the surface is carefully prepared. In addition, the plaster is characterized by high strength, reliability and elasticity.
To select the optimal option of plaster, it is important to first determine for which purposes it may be required - as an aligning lining or for decorating. In addition, it is necessary to determine the climatic conditions in which it will be used, since the composition may have different technical qualities and characteristics, in different ways to protect against moisture and from seismic activity.
Below are the following steps. Collect surface circular motion with 100 gram grinding paper. This grinding removes the shine and creates a profile on the surface to ensure maximum adhesion of the primer. Before applying paint for finishing, let the soil completely dry before easy grinding and polishing of the surface. It perfectly meets the requirements of furniture and cabinets and provides better leveling than ordinary latex paints.
- Then rinse with clean water.
- Follow the instructions for using the product.
- Apply on a professional brush or short pile roller.
Among the main types of such a mixture, the following can be distinguished:
- - It is used in regions with private temperature differences and with high humidity.
- - provides a durable and reliable coating that has such properties such as moisture resistance, hydrophobicity, resistance to UV rays and temperature differences. This is the best and most expensive mixture.
- or plaster - applied to final stage Works with walls. Can be used in a wide variety of climatic conditions. The composition is distinguished by exposure to pollution and has low indicators Parium permeability. The cost of the product is relatively low.
- - Applied to design design. It may be different on the texture - smooth and embossed. Very often there are such additional components as stone crumb, quartz sand and so on.
Sand of the joints, if there are grains and roughness, then dust, and you need to know that in Syo now there are paints that do not require primer, such as Kashmir paints, Shamua and Syo Evolution. Make sure the plaster was dried and flew in favorable conditions and that the room was ventilated sufficiently. Dry plaster should not contain moisture more than 6% when measured using a moisture meter. Re-seal any cracks using plaster, which will be filled after cracking expansion.
Remove the grains and roughness by the scraper. The surfaces, already painted, must be clean, dry, without dust, dirt, fat, oil, wax, rust, chips, or any other pollutants who can adversely affect the adhesion of paints. Product selection manual. Cross the edges of the scale and, if necessary, compare the surface with a suitable placeholder. Clean carefully and make the defatted surfaces of the recommended primer.
Among these species are popular with decorative and silicone plaster. The first is ideally imitated by different surfaces, and the second is distinguished by the high quality of performance and operation.
How to cook stucco with your own hands
For the preparation of a solution and a mixture of facade plaster, you will need to take the main cement substance, gypsum, clay or lime, as well as a filler - water or sand.
Dark circles, food spots and graffiti
The product is prepared in the laboratory in a creamy form, ready for spraying by a simple airless airless sprayer. The product can be pigmented as desired during the preparation stage. This behaves as our skin does not create a "continuous film". Visual appearance And the type of spongy plaster plaster, the feeling and pleasantness is slightly soft if they are removed when removing, the product immediately returns to its original form.
Components of the mixture give the product high elasticity and stability over time. In addition, it can be pigmented directly at the construction site. Visually, he resembles a spongy, the alveolated two-layer plaster, which at the same time is pleasant and slightly soft to the touch; When pressed, it immediately returns to its original form, as soon as the weight rises.
In the process of mixing different components, it is always necessary to be guided by the ratio of the most surround parts. After cooking, it is important to draw attention to the general consistency.
If the mixture obtained in the process of mixing is strongly sticking to the tool, this means that it lacks the filler, if it does not stick to the tool at all - this is a mixture in which the lack of a binder is present.
Coconut plug, sprayed in context
The product is always elastic at any temperature. These characteristics allow you to significantly save energy to cool the summer and warm up. winter. Prevents water penetration into the walls. Eliminates the rise of mold and disputes on the walls. The product is resistant to sea salt. The product prevents water absorption with water and eliminates the risk of mold and dispute.
In addition, it is resistant to sea salts. It can be covered with metal beams of all kinds. It can be used as an anchor base for subsequent finishes. With commercial products or plaster. It does not even create problems in marine areas.
At the normal level of fatty, the adhesion of the solution is average. Without experience in this case, it will be difficult to understand enough, because at first it is better to use certain rules for the relationship.
In the process of cooking a mixture designed to finish the facade, sand and cement are used as the main volumetric components in proportion 1: 3-1: 6, it all depends on the required level of strength of the coating from the grade of the cement used. Cement, when you need to take M400 brands, as this is the highest quality product.
The product can also be used to cover metal farms of any type. It can be used as an anchor base for further finishes created with commercial products or pockets. It can also be used in marine areas.
This is because its properties prevent the water and sunlight into the forest, but at the same time allow you to breathe and move, just think that the plug in nature and the natural protection of the tree. Its functions, in essence, prevent water and sunlight to the forest, but at the same time allow it to breathe and move: because the wild cork acts as a natural defender of trees.
The order of preparation of the solution is quite simple. Initially, the main equity parts of the cement and pre-sifted through the sieve of sandAnd then water is introduced into the solution, with which the plaster solution is brought to the desired consistency. To facilitate work with cement, in it need to add detergents - liquid soap, washing powder, as well as shampoo. These funds are added to the calculation of the tablespoon on the bucket plastering. Such an additive will not give a solution very much, moreover, it will make it soft and pliable.
The product is a ready-to-use single-component component, just add a dye, then mix the product with color and first put on it harmlessly, then apply the second layer by adding inert and large grain for uniform operation. Naturally, the surface is prepared on the basis of the carrier, since the material copies what is lower.
Mix the product and dye and apply the first layer using an airless bunker; Now create a second layer by adding inert material with large grains to align the application. At this stage, just graduate grinding machineto get characteristic white dots. Apply two layers of the protective product on the roller. Since the product reproduces the appearance of the underlying surface, the latter must be prepared in advance in advance.
Preparation of the surface to apply
For high-quality application of plaster, it is important to carefully prepare the walls, as even the highest-quality plaster will not manifest itself in all its glory, if the walls are not properly prepared.
In the process of preparing the walls, it is necessary to thoroughly clean from the old paint coating, from the remains of the old plaster and whitewash. At this stage, you can not strive to achieve optimal smoothness.
The plug applied directly to the screed prevents the transmission of movements on the ceramics. The plug sprayed for use under the tile consists of a special mixture. Inserted various cork granular letters that allow them. High thickness in a short time.
The plug that can be used under the tile can be laid either with a spatula or spraying. When applied directly to the screed, the cork prevents the transmission of motion to the ceramic surface. The sifted tube for applying under the tiles is a special mixture with various plug sizes, which allows you to quickly get the thickness. Apply a plug for tiles or with a spatula or spraying it.
As soon as the initial cleaning of the surface ends, you can proceed to more solid surface preparation.
It lies in the following steps:
- The surface of the facade is prepared as well as. Walls need to thoroughly align, close all chips, cracks and scratches.
- If the surface does not have sufficient density, it can be treated with special regenerating or strengthening soil. Such formulations are ideally strengthening the walls, are an additional protection against destructive dampness, and also improves the adhesion of the coating itself with the surface. If the plaster is applied to the walls of the building located under conditions with high humidity, they will be required to be treated with special antifungal compositions.
- Present cracks need to fully exudeAnd then fill in a special putty composition.
- If several layers of plaster are used, each of the layers need carefully for a day to dry. Each of them needs to be covered with special acrylic soil of special deep penetration.
The decorative drawing does not have to be only in the interior, but it can also be applied to external spaces, where it creates the non-traditional and distinctive character of the whole house. Before the application itself, you need to revise several factors. First of all, this is the plane of the substrate, i.e. Is the maintenance layer suitable for plastering. In addition, the penetrating coating is used, and at the last stage, the grain size and the degree of coincidence of the color shade with the project are checked.
In principle, these are four main steps. At the first stage, the basic layers are roughly applied, most often with a spatula of stainless steel. Excess layers of plaster are removed and the surface is flattened. The plaster structure is first made with a plastic spatula designed to apply decorative plasters. At this stage, it should be noted that polystyrene or rubber spatulas are also available. The thinner structure of the plaster is then performed with a light pressure using a plastic spatula for alignment and combining the structure of the stones.
To polish the surface, finely irrevocable sandpaper. Before making plaster, it is worth producing several paint processes. This will help to pre-assess the texture of the finished coverage, you can also adequately appreciate the color of the future coating.
Reinforcement and priming
After this event Special is applied on the walls . It is necessary in order for the apparent mixture of plaster very well at earlier.
What are the most common mistakes and what to take into account?
The most common mistake is non-compliance with the same layer thickness on the same surface. The protrusions or "sinks" are instantly visible during the daytime, because they discard the shadows. This error most often occurs due to the fact that the excess layer of plaster is not removed, and the structure is immediately converted. A malfunction may also be poorly mixed material or uneven pressure under pressure. Inhomogeneous source material can also cause so-called smooth spots. However, this is not recommended, because it is very difficult if not impossible to achieve the same results.
Competently selected and installed grid will play the role of protection and strengthening.
In the process of applying the grid, it is pre- need to cut on meter segments. More dimensions are not used, as the plaster can simply dry even before its distribution is completed.
After gluing the grid, it must be lost using special mixtures of plaster or construction mixtures.
Difficulties can also cause mechanically more intense areas that have not been reinforced with underlying cloth. In the case of a smaller movement of the house, cracks may occur in the plaster, which in itself is not very flexible, so it is necessary to check and, if necessary, make sure that these problems can be properly verified before applying. Another common error is the structuring of too fresh material. In this case, there may be two factors or simply non-compliance with the recommended period by the manufacturer, or by diluting the plaster, which limits the ability to structuring the grains to create locally smoothed structures.
NOTE!
For facade work It is required to use the mesh, the density of which is 140-160 g / sq.m. It is possible to choose a grid and higher density.
With it, you can get a more flat plastering layer. The only thing to pay attention to what the more dense the grid, the harder it behaves when processing the corners.
Removing a biological attack in an external - colorless cycle
Since there are many opportunities to create unnecessary errors when creating a structured plaster, it is important to consider whether to hire a professional company or at least leave detailed instructions and descriptions. The aesthetic appearance of the existing finish does not change much, and local interventions can be carried out.
This cycle provides very good passive protection against further biological attack, but in the event of a set of unfavorable environmental conditions, it is impossible to exclude green algae or mold in the future by 100%. The cycle consists of three phases, which are described below.
Walls are not only carefully reinforced, but also ground. If the wall adsorbs moisture from all applied materials, 2-3 layers of primer will need 2-3. This is a very important process, since it is the primer that significantly increases the clutch of the surface coating and thereby help overcome the overall wall unevenness of the drying layer.
Also primer serves as protection against different biological formations, which can be called fungus or pests of a different plan. After that, some technological pause is withstanding before applying the primer. Only after that the process of applying facade plaster begins with their own hands.
How to finish a facade of a private house with plaster
Stucco must be applied to the surface of the walls according to a specific instruction. Only so can count on the fact that the facade coating will be not only high-quality, but also attractive.
Here is the algorithm of actions that you need to adhere to the process with plaster (photo below):
- The first layer is applied "splashes" and it is made from enough liquid plaster. The thickness of this layer should be no more than 0.5 cm. The layer purpose is to provide the desired level of clutch of materials. The layer will dry about 2 days.
- After that, the wall is covered with a more thick solution, that is, soil. Its value is to ensure a high level of thermal insulation, as well as waterproof. In addition, this layer perfectly levels the surface. The thickness of this layer is already 2 cm.
- In about 2-15 days, it is worth a special layer of "covering" with a thickness of 0.5 cm. It is necessary to apply it tightly, completely excluding all the gaps and pouring into such a tool like half-sash. How will the subsequent layer be applied, directly depends on the next stage of the facade processing.
One of the most common methods for processing a fully plastered surface is special textual processing.
In this case, special wools are applied, as well as ordinary sponges. Its appearance directly depends on the general properties of the material used, as well as on the degree of coating.
Applied facade plaster be sure to handle. If lime is present in the coating, it can be processed in a plastic condition. Cement composition can be processed after final grasp.
During the processing process, it is possible not only a smooth surface, but also to give a special rough surface. In the second version it will be necessary to use special rubber and metal brushes. The process is carried out at the stage of frozen composition.
Quite often, the surface roughness is attached with brush endingwhich is handled not yet dried decorative plaster.
Fully finished coating is painted and decorated strictly in accordance with the taste of owners. Finishing material It can be used as part of the main fox or marble crumb. Also in the composition may be a quartz sand, which gives the coating an attractive aesthetic appearance. It is also possible to give plaster a certain color, which eliminates to avoid the subsequent staining of the facade part of the building.

Conclusion
The properly selected and applied composition of the facade plaster is able to effectively reflect the overall appearance of the structure, ideally hides quite essential flaws or defects. The plaster performed by its own hands can not only protect the building from destruction, but also gives the perfect appearance to facilities.
High rates of protection of buildings and structures with plaster are based on the fact that all modern compositions are characterized by such important preferential qualities as fire resistance, ability to push water, perfect thermal insulation, as well as sound insulation.
In addition, it is very durable layers that are distinguished by stability to different adverse events, to moisture, it is for this reason that they are protected for the house itself.
If using right plaster, you can be sure that it will be breathable material, frost-resistant and different mechanical strength. Breathability is very important, as the walls get the opportunity to display in environment Excessive moisture, which will automatically accumulate indoors.
If you use poor-quality plaster, it will not remove water, which will automatically lead to serious destruction of the walls. As for the qualities such as frost resistance and mechanical strength, ensures the perfect quality of the whole structure as a whole.
