Facade plaster for external works: especially material

After completion of construction work, proceed to the exterior walls of the building. Quality lining creates not just a presentable appearance view of the structure, but also protects the structure from the negative effects of precipitation, sunlight and mechanical damage. Facade plaster for outdoor work is the most popular material, details of which can be found in this article.

Preparation of the front surface of the putty for exterior

Before proceeding to the finish cladding the exterior walls of the building should prepare the base, using the façade plaster. It is designed for surfacing of concrete, stone, brick, concrete blocks, aerocrete, gypsum board and other materials. Exterior plaster for external works must have moisture resistance, frost resistance, parapronitsaemostyu and elasticity.

Distinguish start and finish plaster facade. The starting mixture used for the base bottom finishing. Due to the coarse structure it is able to smooth out the bumps, swings. Used for embedding the chips and cracks. The result is a strong base. The working solution should resemble the consistency of sour cream. Putty is applied to a layer of no more than 1.5 cm.

The finish coat having a fine structure is used for final alignment of the base and provides a smooth, flat surface for the subsequent decorative facing. Working solution is prepared thinner than the starting mixture. The layer thickness should be not more than 4 mm.

Depending on the composition, putty or cement may be polymeric. The cement compositions have improved resistance to moisture and low temperatures. The cement composition of the starting mixtures present quartz sand, and in the finishing plaster is added marble dust or ground quartz sand. This modest and inexpensive embodiment, however, the surface may cause cracks during shrinkage of the building. Popular brands of cement fillers are Kreisel 662, SCANMIX CT, Knauf Multi-Finish, Plitonit and facade.

Polymeric fillers, which include polymer binders may be acrylic or latex. Acrylic blend moisture resistant, elastic and plastic through the main component - acrylic. This plaster is applied on the pre-primed concrete or foam concrete surface layer of 1-3 mm.

The latex coat is produced on the basis of latex is discharged in the form of paste without odor and emission of harmful substances. This mixture has a high ductility, which prevents the formation of cracks after drying. Despite the high cost, it creates a durable coating. The most popular brands of polymer fillers are considered SCANMIX LH STANDART, Bolars, Parade Classic.

Now you can proceed directly to the decorative design of the building walls, using facade plaster for outdoor work.

Facade plaster for external works: variety and well-known brands

Decorative plaster for the exterior cladding is different from the materials, which are intended for indoor use. The composition of these mixtures contains additives that give the material ductility, toughness, moisture resistance and frost resistance.

Wondering how to choose a facade plaster for outdoor work should pay attention to compliance with the material the following requirements:

• resistance to temperature;
• presence of water repellency;
• higher degree of vapor resistance;
• sufficient strength to protect the building facade from mechanical damage;
• the coating must create a sound and heat insulation;
• increased resistance to harmful radiation;
• availability characteristics decorative composition.

Any exterior finish creates an additional thermal insulation of the building. However, for the thin walls, choose a so-called warm plaster for outdoor work, which included a special filler will be present. This can be perlite, expanded polystyrene, vermiculite, sawdust or foam glass. They increase the thermal insulation properties of the finishing mixture. Thus, in the plaster layer is able to replace 3 cm in their characteristics brickwork 15 cm thick.

Additional acoustic layer operates via the home plaster. For this purpose, its composition should be present pumice, magnesite or cement with slag or pumice. These porous components can partially absorb noise.

Useful advice! If the building is exposed to high levels of noise, external plaster, as a reliable sound insulator, is ineffective. It is further to use mineral wool or foamed polystyrene plate. Also, you can warm the plaster facade.

Among the proposed range of compositions for the exterior can be identified 4 main types of facade plaster, which differ in their properties, composition and application of technology. There is also a fifth type - gypsum plaster for outdoor work. However, it has a high degree of exposure to environmental influences, which makes it impractical for the external cladding. It can be used for alignment or base to prepare the surface for the subsequent decorative facing.

All façade plasters can form a smooth or embossed type "bark beetle"," Coat "or" mosaic. "

Especially mineral plaster for facades

The composition comprises mineral plaster, slaked lime, Portland cement, crushed stone, clay color, additional elements that enhance the performance characteristics of the finished surface and the components responsible for the texture of the finished facade. To increase the resistance to fungus and molds in the composition of the mixture may be additional excipients.

The mixture was discharged into finished packages in powder form, which should be diluted with a definite amount of water to obtain a final solution. It is applied to any type of surface. Before facing the wall, you need to mount the mesh under the plaster facade, which will allow smooth the surface, to create an additional adhesion of plaster to the base and reduce the risk of cracking.

Cement plaster for outdoor work creates a solid "breathing" decorative coating, which does not smolder, not burn and does not emit toxic substances when heated. The suitability of the composition for use is not more than 90 minutes. After drying on the surface of a wall formed nonflammable solid coating with acoustic and heat insulating properties. Decorative materials provide colored additives, and granules.

Useful advice!Due to its low resistance to vibration, mineral plasters should not be used for buildings, near railways and in areas with high seismic activity.

Mineral coating is capable of withstanding temperature variations from -30 to + 45 ° C. without losing any of its performance properties. The lifetime of the coating is at least 15 years.

The color scheme of the cement plaster is very limited, which reduces the degree of its decoration. The finished surface of the cement plaster can be painted in any color, thus create a more aesthetic appearance of the building.

Today, very popular mineral plaster facade of Knauf Diamant range, which have increased moisture repellent properties and resistance to aggressive atmospheric impacts. Using a mixture of Diamond-240 can be obtained textured surface "bark beetle"And Diamant-260 forms a rough lining, which is called" coat ". Price per pack of 25 kg is about 900 rubles.

Another no less popular option is a mineral plaster facade Bolars, which can be bought at the price of 700 rubles. Having a self-leveling structure due modifying additive within its structure, it creates a perfectly flat and smooth surface.

Acrylic decorative plaster for facade of the house

The acrylic composition instead of plaster cement as binder, the acrylic resin applied. Further, the modifiers are used, which increase the ductility and strength of the coating, pigments and one of the excipients, such as crushed stone, sand or colored pellets, which creates the decorative structure surface.

Acrylic plaster is produced in the form of final solution, which is immediately suitable for application. Layer grasped after 20 minutes, and the total surface drying occurs after 48 hours. During this time, should protect the coating from exposure to direct sunlight, which contribute to cracking the facing layer.

Useful advice! Because of the rapid curing on the surface of the joints may be visible layers, so the performance of work is best left to professionals.

A mixture based on acrylic has a high resistance to temperature extremes. It creates a good moisture-resistant surface with additional protection from strong winds. Due to the high elasticity of the coating, it reduces the likelihood of cracking of the surface. The facade, made of acrylic plaster, will have a high resistance to abrasion and impact, which increases the service life of the surface, which is about 20-25 years.

However, it is able to quickly attract the dirt. For surface cleaning is enough to pour water from a hose lining. Another drawback of the outer composition is an acrylic-based pigment instability to ultraviolet radiation, which fades over time. This plaster should not be applied on the basis of mineral wool and cellular concrete walls.

It should be borne in mind that the very light shades quickly fade and discolor, while too dark shades most strongly attract ultraviolet light, which promotes rapid cracking.

Technology of wet plaster facade. Price per m2

Wet plaster facade is considered finishing technology of the exterior walls of the building in which insulation, reinforced with mesh and lining material are fastened using semiliquid or liquid formulations. Thanks to this decoration dew point, receiving the condensate is driven out of the building, which affects the creation of a favorable microclimate in the house. For wet facade characteristic is the use of adhesives, including plasters.

Wet plaster facade is composed of three main layers:

• thermal insulation;
• a base;
• decorative.

Insulation façade plaster is fixed to the substrate using adhesive. For this often used Portland cement formulations which provide adhesion delicious heater and the support base.

It is important to choose a good facade insulation plaster. There are several varieties of this material. The best option in this case is the use of mineral wool, polystyrene or OSB boards. They provide reliable storage of moisture and heat. The average cost of installation of the thermal insulation layer is 500 rubles / m².

The base layer is a rigid layer which protects the insulation from the adverse effects. As interlayer protrude solutions or polymer-reinforced fiber glass mesh. Mounting base layer cost 150 rubles / kv².

Creating decorative layer is to coat the front surface of the prepared plaster. The cost of operation on plaster walls depends on the application method (manual or mechanical) and texture and an average of 400 rubles / kv². Additional staining facing surface will cost from 170 rubles / kv².

The main purpose of stucco facade is completed, finishing external design of the building walls. This decorative coating is an affordable, durable, and has a number of typical distinctive features that make it one of the most popular facing materials.
