Facade plaster can be divided into four types:
- Mineral. It is a cement-sand mixture to which polymers are added to improve the elasticity and adhesion of the plaster. Mineral facade plasters are easy to apply, vapor-permeable, and have water-repellent properties. Due to their vapor permeability, mineral mixtures are suitable for insulating facades using both basalt wool and foam. The disadvantages of mineral plaster include a small resistance to mechanical damage and fragility – after 10 years you will definitely have to repair it, because cracks appear quickly enough. In addition, mineral mixes for facades are sold mainly in bags and in white, you have to paint on top.
- Acrylic. Acrylic resins are the basis of such facade plasters. This type is considered the most resistant to mechanical damage, the facade can last up to 25 years. However, acrylic plasters are vapor-resistant, therefore they are not suitable for thermal insulation of facades with mineral wool. The disadvantages of acrylic mixtures include the fact that they attract dust, which is not washed off by rains. This leads to a deterioration in the appearance of the wall..
- Silicate. This facade plaster, in contrast to acrylic, repels dust, washes well, which allows you to maintain the original appearance of the facade for many years. Plastic, durable, created on the basis of aqueous potassium glass with the addition of plasticizers. It is the plasticity that makes the silicate plaster crack-resistant..
- Silicone. This type of facade plaster is by far the most “advanced” and technologically advanced. It is created on the basis of silicone resin, an even more plastic version with high elongation rates and a long service life – up to 25 years. Silicone plaster is anti-static, easy to clean, can be used on the facades of houses next to dusty roads.
We wrote about the choice of paint for the facade. So, in the case of mineral plaster, it is best to choose silicate paint, which will additionally protect the walls from cracking.
It is important to remember that the smoother the surface, the easier it is to crack. A rough facade will last longer. In our country, the most popular options for plaster texture are corrugated “bark beetle” and a rough “lamb”. “Bark beetle” contains pebbles, this type of texture is often called pebble plaster. The “lamb” can be formed with a roller, simply with a twisted rag, a broom or a scraper, which will provide a different arrangement of plaster lumps.
Important! Gypsum plasters are intended exclusively for indoor use!
As for the price, the most affordable is cement-based mineral plaster, that is, the first type we have described. The most expensive is silicone.
We must not forget that the plastering of the facade is carried out only after the complete shrinkage of the new house has occurred. Of course, first you should complete all work with the roof and wiring communications. The facade must be cleaned of salts, grease and dust, and primed. If the plaster is applied in dry and hot weather, the wall surface should be moistened. The most difficult thing will be to apply a layer of plaster on the mineral wool, if this material was used to insulate the facade.
What are the key features and factors to consider when choosing facade plaster?
When choosing facade plaster, there are several key features and factors to consider. First and foremost, you should think about the climate and weather conditions in your area. The plaster should be able to withstand the elements and protect your building from moisture, UV rays, and temperature fluctuations. It should also be durable and long-lasting to minimize maintenance costs over time.
Another important consideration is the aesthetic appeal of the plaster. It should complement the overall design of your building and enhance its curb appeal. Different types of plaster offer different textures and finishes, so you should choose one that fits your desired look.
Additionally, you should consider the application process of the plaster. Some types may require specialized equipment or experienced professionals for installation, while others can be applied more easily. Cost is also a factor to keep in mind, as some types of facade plaster may be more expensive upfront but could save you money in the long run due to their durability and low maintenance requirements.
In conclusion, when choosing facade plaster, it is crucial to consider factors such as weather resistance, durability, aesthetic appeal, application process, and cost to ensure you select the best option for your building.
When choosing facade plaster, it is important to consider several key factors to ensure you select the right product for your needs.
The first factor to consider is the type of finish you desire. Facade plaster comes in a variety of textures and colors, so you should choose one that complements the overall aesthetic of your building.
Another important factor is the durability of the plaster. Since it will be exposed to the elements, it is crucial to choose a product that is weather-resistant and long-lasting.
Additionally, you should consider the maintenance requirements of the plaster. Some types of plaster may require more frequent upkeep than others, so choose one that fits your maintenance preferences.
Lastly, make sure to consider the cost of the plaster. While it is important to stay within your budget, it is also important to prioritize quality to ensure the longevity and appearance of your facade. By carefully considering these key features and factors, you can choose the right facade plaster for your building.
