Silicone facade plaster and its application

When there is a need to update the facade of the house, the question arises of the choice of finishing material. It is necessary to use a sufficiently strong, wear-resistant, with a long service life, having a spectacular appearance composition. These properties are characterized by silicone plaster for the facade.

Varieties of facade plaster

Finishing mixture is distinguished by the components that make up its composition:

• Mineral (see Mineral facade plaster: material features). Belongs to the cheapest, contains cement, so it is used to create a solid surface.
• Acrylic, which contains acrylic resin. The solution is characterized by elasticity, high resistance to ultraviolet and temperature fluctuations.
• Silicate is particularly durable, the longest life, endurance against mechanical damage, the harmful effects of the external environment, this facade is not prone to deformation and for a long time maintains an impeccable condition.

Silicone facade plaster for outdoor work is very popular today, it has good strength, elasticity, the solution is universal, but costs significantly more than other types. It turns out a "breathing" facade, to ensure high-quality thermal insulation, mineral wool (polystyrene foam) is laid.

The main types

Types of silicone decorative plaster

Types of silicone facade plaster, the most popular of them are:

It is convenient to use silicone plasters for the facade:

• They are packaged and sold immediately ready for use.
• The composition contains silicone resins (the main component), which give self-leveling properties.
• She cleans herself in the rain. Therefore, they are characterized by greater elasticity, stretch better than acrylic solutions.
• The surfaces of such facades do not crack. It is odorless, suitable for covering wooden structures.
• Its composition includes various pigments, which gives the mixture specific colors.
• When it is necessary to obtain a specific shade, the composition is tinted. The surface thus formed does not require additional care.The mixture has dust-repellent properties.

Note. Finished surfaces are resistant to precipitation, they do not fade under the sun, fungus, mold does not develop on them.

The solutions retain heat well, the coating serves as an auxiliary insulating layer.

Key Features

The development of technology has led to the creation of the best plaster in many respects.

It is chosen for outdoor decoration with high humidity:

• Heavy rainfall is not able to destroy its structure, because the mixture has low water absorption.
• Strength, elasticity gives it the ability to maintain its integrity in the process of shrinkage of a new building.

Note. Silicone decorative plaster for the facade is characterized by good vapor permeability. Thanks to this property, a favorable microclimate is maintained inside the building. In winter, condensation does not form under the finish, so the walls do not get wet.

• The ability to repel water allows mixtures to perfectly pass moisture (slightly weaker than mineral ones) and allow the walls to “breathe”.
• Depending on the design of the facade, you can choose the appropriate texture, shade of the solution.
• You can combine the insulation of buildings with decoration. The mixture has all the qualities of other finishing materials.

Facade silicone plasters, like mineral mixes, withstand high temperatures and do not burn. The color of the solution can be given any shade.

Important benefits

Stucco Benefits

The advantages of this finishing material:

• High strength, elasticity.
• Appearance.
• Suitable for outdoor use.
• Good performance.
• It does not contain toxic, fire hazardous elements.
• Provides protection against aggressive environmental influences.

Let's consider in more detail:

• Facade silicone plaster is characterized by excellent adhesion with various substrates, which are often silicone putties (after removing defects on concrete facades).
• It is recommended to pre-coat the walls with a silicone primer to ensure reliable adhesion to the base. Only after this is the solution applied.
• This mixture combines the best qualities of classic mineral, acrylic plasters.

Note. It differs from other types of decorative mixtures, combining their best properties. Final paint finishes are not always applied on top. The mixture itself is able to decorate the walls of the facade.

Application Principles

There are a number of ways to apply silicone plaster for the facade:

• Manual, which can be studied on video, this article describes common points.
• Using special devices.

Before application, the mixture is stirred until uniform:

• A layer is laid no thicker than the filler fraction that is part of the composition. First, you should clean the surface of various elements that reduce adhesion to the surface.
• If deep cracks are present, then they must be reliably repaired with putty (the instruction describes this process in sufficient detail).

Tip. In order to avoid color differences, it is recommended not to wait until the first layer has completely dried. This method has been called wet to wet. Coatings are leveled, and later the image is applied.

Conclusion

Facade silicone plaster makes it possible to depict any finish (brick, stone, granite, marble, wood, Venetian, etc.). It allows you to form relief images for subsequent painting. For the drying period, the surface should be closed from the sun, wind, precipitation. After drying, you can safely start painting.

When working with this plaster, you must follow the safety rules. For example, avoid contact with the eyes, and the solution should be worn with gloves with goggles.If the composition gets into the eyes or other parts of the body, rinse immediately with plenty of water.
