A key component in improving the resilience and visual appeal of home facades is vapor-permeable plaster. This particular kind of plaster prevents water damage to the underlying structure while allowing moisture vapor to pass through. It’s not only intended to serve a practical purpose but also to improve the building exteriors’ aesthetic appeal.
There are several varieties of vapor-permeable plaster, each designed to suit particular climates and architectural motifs. The composition of these plasters strikes a compromise between weather resistance and breathability, allowing moisture from within the building to escape without jeopardizing the integrity of the facade. This gives them versatility in application and makes them appropriate for both new construction and renovation projects.
Vapor-permeable plaster is typically applied in layers to exterior walls to produce a smooth and long-lasting surface. It acts as a barrier to keep out moisture while letting the facade "breathe," which stops condensation from building up and causing mold and structural damage. Because of its dual purpose, it’s perfect for areas with different climates where it’s important to maintain ideal indoor humidity levels.
Vapor-permeable plaster is appreciated for its aesthetic properties in addition to its practical advantages. It can be tailored to match the architectural and interior design tastes of homeowners by choosing from a variety of textures and colors. This plaster allows for creative freedom in facade design, whether it is utilized to draw attention to architectural details or to accomplish a particular aesthetic theme, like traditional or contemporary.
The comfort and durability of exterior walls in homes can be greatly impacted by the type of plaster used. There are several varieties of vapor-permeable plaster that are appropriate for different climates and building materials. This type of plaster lets moisture escape while providing protection from the elements. This article discusses the various kinds of vapor-permeable plaster that are available, when and how to use them, and how they can improve the longevity and visual appeal of home facades. Comprehending these facets can aid homeowners in making knowledgeable choices to preserve the aesthetic appeal and usability of their dwellings’ external surfaces.
What is the vapor permeability of plaster
One criterion used to assess a material’s capacity to let air and steam through is its vapor permeability.
It makes sense that plaster having a high vapor permeability indicator is referred to as "breathing" because it prevents condensate from building up inside the space. This is without a doubt a huge benefit, as high humidity causes mold and fungus to grow on the walls, which can worsen the condition of the building’s supporting structure and cause allergies and other diseases in both adults and children. Additionally, frost resistance indicators are severely ruined by the regular absorption of a significant amount of moisture into the house’s facade. As a result, everyone residing in the home is directly impacted by the walls’ vapor permeability.
Scope of use of vapor -permeable plasters
The following tasks are excellent uses for steam plaster:
- Alignment of the walls. This is relevant if the walls have strong changes and irregularities, as well as if their subsequent decorative decoration is planned.
- Creating the basis for future tile finishing.
- Building facade decoration. Faced plaster vapor permeable is now gaining great popularity, thanks to its qualities and undeniable advantages.
Types of vapor -permeable plasters
Currently available on the market are the following types of vapor-permeable plasters that can be used to decorate facades:
1. Mineral cement. Professional builders typically favor this kind. the cement-infused sand’s composition. resistant to the growth of mold and UV radiation. Applying to the wall was not too hard. Because the raw materials are inexpensive, mineral plaster is relatively inexpensive, but it stands out for having exceptional vapor permeability. Many also mention how resistant and long-lasting such a coating is.
2. Plaster of silicate. It is then mixed with liquid glass, which offers the maximum amount of vapor permeability. does not gather dust on its own. stops the fungus from spreading. Regretfully, silicate plaster can become slightly discolored when wet, but the color returns to normal once it dries.
3. Plaster of silicone. Silicone resin is a component of such a mixture. This type of plaster has outstanding vapor permeability. Furthermore, silicone coating does not suffer greatly from high humidity. A vast range of hues and textures are reflected in the stores. Among the drawbacks are the coating’s exorbitant price and challenging application.
4. In terms of plaster. Such material does not require any surface preparation before use. Furthermore, the cost of this plaster is fairly reasonable.
Since acrylic plasters have a very low vapor proceeding, they shouldn’t be taken into consideration if this metric is crucial. However, this kind of coating is highly elastic and resistant to mechanical harm.
For exterior work where grout may be used, many experts advise selecting vapor-permeable plasters because they have an adequate amount of polymers. Here, though, each person has already selected a good option for themselves, taking into account their unique living circumstances, budget, and the features and accessibility of a specific coating type.
Work tools
Plastering wall tools will make the material application process more effective and uniform. The following instruments are used by the master to apply plaster to the building’s facade:
- Trowel, bucket or kelm for the initial laying of the material.
- Terka for subsequent wall grouting.
- The rail then check how well the plaster is applied. To do this, it is applied both vertically and horizontally. The most acceptable deviations are no more than 7 millimeters.
- Penter will help get rid of the residues of the solution on the walls.
- The beacons are set to eliminate various irregularities on the surface.
- The old plaster layer from the walls is knocked down with a hammer, and the solution is tapped.
- Mixing container.
- Gloves to protect the skin.
- Mixer or a special nozzle for electric drill to mix the mixture.
- Sandpaper (preferably with large grain).
- The rule is controlled by the alignment of the angles.
Rules for working with vapor -permeable plasters
When decorating, the procedure is essentially the same as when using other kinds of plaster.
First things first, you must clear the wall’s surface of all dust and pollutants and remove any irregularities. The walls must also be near if there are any cracks or other damage.
Prime the surface after it has been prepared. You now need to practice patience and allow the primer to fully dry.
The layer reinforcement phase is the following. A reinforcing grid composed of specialized fiberglass is used for this. You shouldn’t cut corners on this procedure because a subpar grid will collapse very quickly due to the plaster’s high-altitude composition. Note that walls do not need to be reinforced by arbolites.
If the exterior of the house was finished with vapor-permeable plaster, then the interior walls ought to be coated in the same substance.
The applied product is periodically misted with clean water during hot weather. This prevents the coating from drying unevenly and developing surface cracks.
Plaster should have an inner layer that is twice as thick as an outer layer.
The air temperature cannot drop below 5 degrees Celsius while operating.

Vapor-permeable plaster is a flexible way to improve the resilience and visual appeal of building facades. It is perfect for a variety of climates and building types because it lets moisture vapor pass through while keeping water out. There are various varieties of this plaster that are designed to fit particular substrate materials and environmental conditions.
When it comes to exterior applications where moisture control is essential, vapor-permeable plaster really shines. By allowing walls to breathe, it helps maintain a balanced indoor climate by preventing mold and structural damage brought on by trapped moisture. This plaster offers a protective layer that increases longevity and lowers maintenance costs, whether it is being used to build new facades or renovate existing ones.
Vapor-permeable plaster has decorative uses for facades beyond its practical uses. With its variety of textures and finishes, architects and homeowners can create a wide range of visual effects. This plaster gives buildings a more polished appearance while maintaining their structural integrity. It can be used to create textured finishes that resemble traditional materials like stone or stucco, or it can be smooth and modern.
