Wet facade plaster - technology, photo, video. The field of construction in the modern world is used with great success for new technological developments and building materials. The relatively recent buildings look neat, elegant and beautiful. In addition to the aesthetic side of the medal, we also note the quality indicators. These houses can be used for a long time and they can withstand the negative influences of the environment.
A particularly attractive design is obtained when wet plaster is used for the facade. It makes the building beautiful, as well as insulates and protects against wind, mechanical type of impact and moisture.
Let's take a closer look at the issue and find out what types of plaster are suitable for decoration, as well as how to properly organize work on applying plaster to the facade.
The name of this building material was not derived from unusual appearance, and taking into account the fact that to carry out the required work, you will need special finishing materials. Compositions for this design have a high water content.
This technology appeared in Russia due to the fact that domestic builders borrowed it from the countries of Western Europe in the 70s, and gradually the technology became popular among the local population.
Let's look at all the pros and cons that experts were able to note in the composition of wet plaster.
Based on the described advantages, you can add high-quality and practical materials to the list, but do not forget that there are disadvantages.
The surest action in such a situation would be to create a high-quality waterproofing layer.
For this reason, to ensure a long service life and preservation of the building, finishing materials should be used that will have all the necessary technical characteristics.
The main and first difference between the compositions is the way of finishing. With dry plaster, drywall is used, therefore this method is practically not laborious and not costly.
For the technology of wet plaster of the facade, it takes much longer to apply the composition and make great physical efforts. This finishing method is suitable even for walls that suffer from high levels of humidity. The plaster will absorb condensation and the dew point will be moved outside the house.
But inside the premises it will be warm and dry enough, and the microclimate will be better. Dry plaster is more suitable for finishing work inside the building, since it does not have high technical characteristics and does not tolerate low temperatures poorly.
Both types of plaster are used to finish a previously prepared facade, since the final thickness of the coating should not be more than 0.5 cm.
In addition, the walls must be covered in addition to plaster with special mixtures - this will make it possible to ensure the surface evenness and maximum adhesion to the putty. Both types of mixture can be finishing, as it is used for the final finishing of the outer surface of the walls of various buildings and structures.
The intriguingly named "wet plaster" finishing method has many advantages, especially when the walls of your house are very damp and dry plaster is simply not suitable.
This material will easily absorb moisture, thereby helping to provide a warm, dry indoor climate.
Important! The main feature that appears when working with wet plaster is the organization of multi-layer finishing.
Each layer has its own thickness. In a standard application, the finish will look like mineral wool, initial plaster, fiberglass mesh and decorative putty / paint. If you want high thermal protection, wet plaster can be of different thicknesses, as well as other layers.
If there is such a problem as wet soil near the house, then additional finishing will be needed for the basement of the house.
Despite the fact that it takes a lot of effort to apply wet plaster, and all this will be accompanied by a lot of dirt, this technique has a huge number of advantages.
Advantages of the technique:
Each of the qualities described above makes wet plaster a practical and versatile material. In addition to the described characteristics, other indicators should also be noted, namely the ease of application and the elasticity of the material. When choosing a putty, you should consider the type of binder, the manufacturer and the cost.
Ideally, you should buy finishes only from trusted companies, as this will guarantee the high quality of the products on sale.
Before starting the facade finishing with wet plaster, preparatory work should be carried out.
In general, they are quite simple and even a beginner can do them.
Please note, that all slabs that are used to create thermal protection of the facade must be planted on the glue.
It is very important that they are securely fastened and that they can withstand the rest of the finishing steps.
An important preparatory stage is the installation of a reinforcing layer on the facade. This event is held after three days from the date of installation of thermal insulation. To do this, you first need to apply a layer of glue, and then you can start laying a reinforcing mesh on it and cover it with special plaster. After the walls have dried, you can begin to finish the facade with wet plaster.
When the wall surface is ready for the final finishing, a profile bar should be installed, which will make it possible to protect the walls from moisture absorption in the first row of insulation, as well as for the most even fit of the heat insulator plates.
Installation of the profile strip is carried out on the basement floor and for this use dowels and self-tapping screws. Fasteners should be installed in 0.2 meter increments. It should be borne in mind that the height from the ground should be no more than 40 cm.
the gap between the strips should be 0.3 cm. To ensure protection of the corners of the structure, an angle profile should be used.
All previously applied layers will dry for a week, after which the last one is required - the application of an outer layer of putty. The composition should be applied to the prepared reinforcement and for this use the finishing building mixture, which is used for outdoor work.
You can also additionally use a special adhesive if you plan to apply a layer of decorative plaster in the future.
After 4-8 days for the applied layers to dry, you can start to apply the leveling layer. There are several nuances of plastering, which play a significant role in the facade decoration. If the walls of the facade are exposed to excessive moisture, then instead of insulation, it is worth using mineral wool, as it will perfectly resist the development of fungus or mold.
In some cases, the plaster should be applied in a thick layer and then the weight will be higher.
This should be done to reduce heat loss. It is the thickness that will play a big role in this case. The first layer of plaster should be applied with a thickness of at least 0.2-0. 3 meters.
It is important that the insulation layer is of the same thickness. Naturally, the mass in this case will turn out to be quite large, therefore, additional dowels are used for fixing, as well as a plinth strip and hooks.
The protruding mesh for reinforcement must be rubbed with a certain adhesive composition with a thickness of 0.5 cm. After that, the mesh should be reapplied and the last layer of 2-3 cm should be applied.
Finishing should be done in 2 layers. The technology of finishing the facade with wet plaster should be supplemented by finishing the basement walls, provided that the soil near the house is wet, and this will require the use of moisture-resistant and non-absorbent material. Before you start applying the leveling layer, you should impregnate the walls with a primer that has antiseptic properties.
This video tutorial presents a master class on applying plaster with your own hands:
Wet plaster has become quite popular in the past few years and is often used for finishing buildings. The facade of the building, which is decorated in this way, has a beautiful appearance and is highly durable.
It is also important that it will perfectly absorb moisture and will become an additional means of protection against negative influences - moisture, wind and rain. When using this material, you can increase the life of the building by several years and get an excellent finish. Wet plaster lasts a long time, and also does not deform or burst.
