Facade plaster silicate – advantages, how to choose and work with material

Facade plaster is a highly versatile option for improving the exterior appearance and longevity of your home, particularly when it comes to formulations based on silicate. Silicate facade plaster is favored by both builders and homeowners due to its many benefits. It offers flexibility in terms of aesthetics as well as weather resistance, enabling a variety of textures and finishes to go with different architectural styles.

Selecting the best silicate facade plaster requires taking into account a number of variables. Durability comes first and foremost. Because silicate plasters have a high resistance to weathering, your facade will continue to look flawless over time. Furthermore, search for plasters with breathability; this helps avoid moisture accumulation behind the facade, which over time may result in structural problems.

Applying and preparing silicate facade plaster requires careful thought. Make sure the surface is dry, clean, and free of any impurities that might impair adhesion before applying. It is essential to mix plaster according to the manufacturer’s instructions in order to obtain the right texture and consistency. Application methods differ depending on the type of finish you want—a smooth, textured, or patterned surface—so it’s important to educate yourself on these methods in advance.

In conclusion, silicate facade plaster is a popular option for homeowners wishing to improve the exterior of their homes because it combines practical durability with visual appeal. Through comprehension of its benefits, appropriate product selection, and application skill development, you can create a facade that is not only visually striking but also long-lasting.

Silicate-based facade plaster is a multipurpose material that is well-known for its brevity and longevity, which makes it perfect for improving the outside of homes. The advantages of silicate plaster are examined in this article, including its capacity to control moisture and its resilience to weathering. It gives readers advice on how to select the best kind of silicate plaster for their requirements and tastes, taking into account things like available color options and application methods. Both professionals and do-it-yourselfers can achieve a successful result by following the helpful advice on priming surfaces and plaster application. Gaining an understanding of silicate plaster can greatly improve both the practical and visual aspects of the facade of your house, whether you’re building from scratch or renovating.

What is the material

Because the foundation of this kind of cladding is liquid glass, the coating is incredibly robust and long-lasting. Furthermore, the plaster offers additional benefits.

• the material is not exposed to ultraviolet radiation;
• not afraid of moisture;
• mold does not live on the surface of silicate plaster;
• The material does not burn;
• plaster passes the air, so the walls under it "breathe";
• The wall covered with this cladding is better protected from the cold;
• The coating has a rough structure, therefore, visually hides the irregularities of the wall;
• The cost of the material is low.

When considering the purchase of silicate facade plaster, the following drawbacks should be considered:

• The material dries quickly after application, so you need to work quickly;
• The wall before work needs to be prepared: clean and apply a special primer;
• Silicate textured paint has a poor selection of flowers, and only a specialist can add a colorer to the mixture.

Despite these drawbacks, brick, block, monolithic, and shield houses are frequently covered from the exterior with this kind of facing.

Technical characteristics and composition of silicate plaster

Silicon-containing autoclave processing is used to turn raw materials into liquid glass, or potassium and sodium silicates. After application and solidification, the resultant substance dissolved in water acquires a smooth "glass" appearance and high strength.

Various mineral fillers (granite, metal and marble chips, colored sand, cement) are included in the plaster’s composition to create an intriguing embossed surface. There are resins and specialty additives in the mixture to increase its plasticity. The color pigments in plaster are what give it its shade.

The primary technical attributes of the substance are:

• density from 1600 to 1850 kg per cubic meter;
• the range of permissible temperature during operation is from -50 to +70;
• The type of surface for application is concrete and aerated concrete, brick, drywall, slag block, insulation – mineral wool;
• consumption of 1m2 from 2 to 4 kg;
• Drunger – water;
• durability from 20 to 50 years;
• Sedimentary resistance occurs 2 days after application;
• application temperature from +5 degrees;
• The coating dries for 3 hours, the second layer can be applied after 12 hours.

Silicate facade plaster is available as finished pasta or as a dry powder that needs to be mixed with water before applying. Pasta has a maximum shelf life of one year, while powder can be kept for up to two years.

Types of silicate plaster

The final surface may have a different texture depending on what kind of extra ingredients were added to the main mixture.

• bark beetle (large sand);
• fur coat (stone particles, from 1 to 4 mm in size);
• mosaic (granite, marble or quartz crumbs).

The pronounced relief surface gives the coating’s color depth and volume, and it also makes it possible to visually conceal minor wall irregularities.

"The builders are highly well-liked for their use of silicate silicone plaster on the exterior. This mixture is easier to work with because it has more elasticity while maintaining all the benefits of the silicate composition.

The best manufacturers of silicate plaster for facades

Materials and tools for working with material

To avoid becoming sidetracked while applying, the entire tool must be ready before beginning work. Within three hours, a solution needs to be applied to the whole painted surface.

In order to work with decorative plaster, you need:

• trowel (Kelma);
• brushes;
• curly spatulas and rollers to give the desired surface structure;
• grater;
• metal brush for cleaning the working surface;
• level;
• beacons;
• Rule.

The task will go much faster if a pneumatic pistol (bucket) is used. Comparably to a spray gun, this device uses a compressor to instantly apply the solution to a sizable surface. Since buying one of these units for personal use would be economically unfeasible, they can be rented.

To prevent breathing in mineral dust, it is imperative to use a respirator and safety glasses when working with the solution. When operating at an elevation of more than two meters, the use of construction forests and insurance is required.

How to prepare the surface for application

The wall is cleared of impurities and the previous coating before a decorative solution is applied. Make use of metal brushes, scrapers, spatulas, and a drill with a special nozzle (a chisel).

A primer is applied to the cleaned wall. It is necessary to have this before handling plaster. Manufacturers of facade mixtures typically also supply primers appropriate for this kind of coating.

Filling the shock or reinforcing mesh on the wall is required if the solution is applied to a wooden surface or insulation (mineral cotton wool). This will strengthen the coating and improve the clutch of the solution with the wall. Using a drill and a cutting circle, notches are made on the smooth concrete surface for the same reason.

In order to employ less decorative plaster, any bumps on the surface (cracks, deep potholes) are first filled with a sand-cement mixture.

Selecting the appropriate facade plaster—such as silicate—can greatly improve the external appearance and longevity of your house. Because silicate plaster breathes well and resists weather well, it can be used in a variety of climates. Because of its mineral makeup, the facade can effectively control moisture, which lowers the chance of mold and mildew developing.

When choosing silicate plaster, take into account elements like texture and color selections to match the design of your house. Because of its strong bonding with mineral substrates, the plaster is long-lasting and requires little upkeep over time. Vibrant colors are preserved for years, contributing to the facade’s aesthetic appeal due to its inherent resistance to UV rays.

When working with silicate plaster, meticulous substrate preparation and application methods are required. To achieve a seamless finish, make sure the surface is clean and clear of dust or other contaminants. Usually, application consists of applying an even layer of base coat, then a layer of finishing coat to get the desired texture and look.

All things considered, silicate plaster provides homeowners with an attractive, long-lasting way to enhance and preserve the exterior of their house. Because of its inherent qualities, it’s a sustainable option that promotes indoor air quality by letting the facade breathe. For a blend of longevity, practicality, and aesthetic appeal, silicate plaster is a good option for new construction or renovations.
