Wet facade is a facade finishing technology using several layers of materials (thermal insulation, rigid layer, decorative plaster). The basis of wet facade technology is the use of construction and adhesive mixtures. This technology for finishing walls and building facades is widely used in both the commercial and residential sectors. Suitable for various types houses and wall materials, looks presentable, easy to maintain.

1. Thermal insulation (facade insulation).
   The first layer of a wet facade is thermal insulation (slabs of mineral wool or penoplex), which is attached to the wall material using a polymer-cement mortar. The solution reliably glues the insulation to the rough walls.
2. Base material (hard layer).
   The second layer is a polymer cement solution together with a reinforcing mesh. This combination of materials simultaneously protects thermal insulation material and serves as the basis for finishing walls
3. Decorative coating (plaster).
   The third layer is decorative plaster or special paint. A wide selection of textures and colors opens up great opportunities for decorative design facade of the house.

Advantages of wet facade technology:

• Low price (compared to other options for major façade finishing);
• Minimum load on load-bearing walls(due to light weight materials);
• Wide selection of decorative finishes and textures (implementation of any design ideas);
• Possibility of painting in any color or various color combinations;
• Excellent compatibility of the technology with elements of decoration and lighting of facades.

A ventilated façade is modern technology façade repairs and exterior finishing walls using a frame made from a system of profiles and facing materials(porcelain tiles or composite panels). The supporting structure in the form of a frame ensures even and rigid fastening of materials at the required distance for free air circulation.

• 
  Heat-insulating material for insulating a house (mineral wool or expanded polystyrene) with a moisture-proof film can also be used.
• 
  The basis of the design is the supporting structure - a universal subsystem of profiles and components specially designed for quick and durable cladding of any type of building and structure. Allows you to easily and quickly prepare walls for further cladding.
• 
  According to the air gap between the cladding and load-bearing wall air circulates freely, which protects the structure from moisture and condensation.
• Facing material (porcelain stoneware or alucomposite material).
  Special composite panels or porcelain tiles are used as finishing materials. Today there are many manufacturers finishing materials provide a wide choice of colors and textures, allowing you to realize a variety of ideas.

The main advantages of hinged ventilated facades:

• Possibility of quick installation, regardless of the time of year;
• The versatility of the design and material allows the use of ventilated facade technology for cladding any types of buildings and structures, as well as various architectural forms and elements;
• Durability of the cladding, supporting system and components ( average term service - 50 years);
• Large range of colors and hundreds of options for imitation of natural materials;
• Convenient operation, maintenance and repair in case of damage;
• Heat and sound insulation, no overheating of walls and removal of the “condensation point”.

Facade plastering is a repair using facade plaster, carrying out preparation and plastering work external walls building. Characterized by accessibility, simplicity and speed of implementation repair work. Depending on the wall material, the optimal type of plaster is selected.

Before plastering the facade, you must first prepare the walls - clean and prime the surface. The plaster is applied in 3 layers - base, main and finishing. For optimal adhesion of the plaster, a reinforcing metal mesh is attached to the walls or insulation.

The plaster solution is applied using a special pneumatic bucket or manually. Next, the solution is leveled along special guides. The next layer of plaster creates adhesion to the finish. Finishing layer rubbed over or decorated with a relief (pattern).

Types of plaster for facade finishing:

• Acrylic (based on acrylic polymer resins with low vapor permeability);
• Mineral (based on quartz or marble chips);
• Silicate (based on " liquid glass"—a solution of sodium and potassium silicates);
• Cement (cement is used as the base);
• Silicone (based on silicone resins).

Advantages of decorative plaster:

• Low cost, ease of implementation and lightness of materials;
• Optimal material quality and strength level;
• Heat and sound insulation, moisture protection, resistance to weather conditions and temperature changes;
• Wide selection of colors and textures for painting and decoration;
• Perfectly combined with decorative elements for finishing external walls and facades.

Siding finishing involves external cladding building walls with panels. This finishing method has become widespread due to its reasonable price combined with the simplicity and quick implementation of installation. Siding is used for finishing residential and commercial buildings of all types.

Types of siding (panel materials):

• Wooden (wood-polymer).
  For exterior finishing siding made of wood-polymer materials is used on the walls - a mixture of wood fibers and plastic. Service life - from 15 years, easy to maintain - no need to tint, impregnate, or varnish. The material does not absorb moisture and is not flammable.
• Vinyl (made of PVC plastic).
  Vinyl siding is the most common type of siding due to its low price combined with a wide selection of colors, as well as durability and ease of installation, operation and cleaning. The material is suitable for all types of buildings and climatic conditions.
• Metal (galvanized steel).
  Metal siding is most often used for commercial and industrial buildings, but is also suitable for residential buildings.
• Fiber cement (made from cement with the addition of cellulose).
  Non-flammable, durable and durable material increased resistance to moisture, mold and mildew. Mainly used for commercial and industrial buildings.

The main advantages of finishing facades with siding:

• Minimum terms for installation, regardless of the time of year (preferably from +5);
• Universal material and installation system - suitable for finishing any type of building;
• Wide selection of colors and types of material (many shades and textures);
• Easy to operate, maintain and repair;
• Protection of walls from moisture, temperature fluctuations and condensate drainage.

Facing the facade with clinker tiles or bricks is a premium option for finishing the facade with imitation brick or stone. The material is based on natural clay, fired special technology. Clinker tiles - affordable option brick-like cladding, both external and interior walls building.

• Thermal insulation (wall insulation).
  Thermal insulation material (mineral wool or polystyrene foam) with a moisture/windproof film is used to insulate the house.
• Subsystem (steel or aluminum frame with components).
  A design made of profiles and components specially created for finishing with clinker tiles. The elements of the subsystem allow the finishing process to be carried out quickly and efficiently.
• Air gap (ventilation).
  A special distance between the cladding and the walls ensures the necessary air circulation to protect against fungus, moisture and condensation.
• Facing material (clinker tiles or bricks).
  Clinker tiles are made from clay and sand, which are pressed, molded and fired at temperatures of more than 1200 degrees. The desired color of clinker tiles is achieved by different firing temperatures, so each batch of tiles is individual and may vary slightly in shade.

Possibilities of clinker facade technology

Work on insulating the base walls of a building represents a complex of works on the preparation and installation of a heat-insulating layer. At the moment, there are two main options for insulation for external finishing - mineral wool slabs or expanded polystyrene.

The technology for insulating walls from the outside is correct, both in practical terms (savings usable area), and the technical side (protection of walls and removal of the point of condensation formation). The base walls are prepared and primed, then the insulation is installed using an adhesive solution and additionally reinforced with dowels.

Mineral wool slabs
Basalt mineral wool is inexpensive and effective method insulate any type of building. The mineral wool layer must be protected with vapor and waterproofing. Insulation with this material is ideal for wooden houses, and also goes well with “wet” facade technology.

Foam plastic (expanded polystyrene, penoplex)
Polystyrene foam is an economical, very lightweight and easy-to-install material that also has good sound insulation. However, foam plastic does not allow air and steam to pass through, which requires equipping the house with a ventilation system. Also, foam plastic requires reliable waterproofing, because... susceptible to moisture. The use of foam plastic is recommended in combination with ventilated facade technology.

The main advantages of facade insulation:

• Increased energy efficiency, reduced heat loss and heating costs;
• Universal materials - suitable for insulating any buildings;
• Protection of walls from moisture, temperature fluctuations, external influences and removal of the “dew point”.

Facade repair

Facade repair

Facade repair– restoration or reconstruction of old coatings, as well as a complex of facade works to replace technologies for finishing the external walls of private houses, administrative buildings, industrial complexes and residential buildings.

We are not considering the option of new construction (you can read about technologies for creating building facades on other pages of our website). Reconstruction of facades involves working with existing defects in the walls of the building, the consequences of poorly performed facade work, and the results of using the facade for a certain time.

The Bau-Group company identifies three main problems with the condition of the façade in need of reconstruction.

1. Poor execution related work or improper operation building.

   There are many harmful and aggressive factors affecting the condition of building facades. These are temperature fluctuations, frost and wind, ultraviolet radiation and oxides, exhaust gases and dirt, microorganisms, etc. The façade is “afraid” of water. Water destroys the facade quickly, and in combination with weather conditions in Russia (numerous zero crossings) - even faster. Therefore, first of all, in order not to constantly repair the facade, it is necessary to ensure that there is no access of water to the facade of the building and inside the system. We are not talking about “slanting rain”. And we are talking about the roof, parapet covers, eaves and window sills, impeccably executed basement waterproofing and proper operation of the building in winter period, control of drains, etc.

2. The quality of the work is the quality of the materials.

   Materials. Naturally, saving on materials reduces the service life of the facade. But, from our point of view, this is not the main problem of repairing the facade of a cottage or administrative building, although it is also significant. Because a professional will refuse to work with low-quality or “weak” material. We have extensive experience in repairing building facades. And this experience says that WE are responsible for everything. Even for the Customer. We don't want this, believe me. Imagine how you can be responsible for a Customer if he is a year old!!! installs parapet covers, but the already installed façade suffers and water enters it. Therefore, we simply do not undertake to work when the selected materials or technologies do not lead to high-quality results. This means this is not our object, not our Customer, not our philosophy.

3. The quality of the work is the qualification of the builders.

   It is impossible to do well what you cannot do or do rarely.

   Interior specialists who believe that the repair of facades of residential buildings and the renovation of premises are one and the same thing, introduce interior mesh, gypsum putties into the facade system, confuse technologies, etc. Firms and teams that fail to organize work save on everything. They hire unskilled workers, do not have engineers on staff, and simply do not like this work, do not know how, and most importantly, do not want to waste time on solving the problems that have arisen. Everyone makes mistakes, it’s almost impossible to take into account and provide for everything (try to take into account the shrinkage coefficient of the building, if during the examination of the facade “curved” beacons are found in the basement of the house - not a single facade insulation system will withstand it, no matter how well you make it) - but the question in how we solve problems that arise, how we worry about the results of our work, and how much effort we put into it.

   The teams know how to do something, they know the façade operation “A”, but they forget the operation “B”. And often they simply don’t know the technology and do things on the façade that are prohibited by SNIPs.

4. Repair and finishing of facades - common mistakes and difficulties.

   The first paragraphs describe the main criteria that lead to negative results. construction work on the facades of buildings. To this we add general trends in the construction industry:

   • weak or incorrect design decisions. For example, they put decorative element on the facade of the house, but they forget to protect it from above with low tide. The decor will stand, but dirt from snow and rain on top will cause a dark streak on the façade. A trifle, but, unfortunately, a common one.
   • desire of customers to save on facade work. There is enough money for the monolith, but they are starting to save money on the facades. The façade comes at the end. There is no funding left.
   • difficult situations, related to the specifics of a particular object - shrinkage of the building, wind load, approaches to organizing work by customer services, etc.

Types of repairs

Cosmetic repair of facades- easy updating of the “freshness” of the facade. Fill out the cracks, putty, and paint the facade. Sometimes, to significantly increase the maintenance-free service life of a facade, it is possible to use separate processes from SFTK technologies - applying reinforcing reinforcements adhesive compositions and finishing plasters.

Major renovation of house facades– complete refurbishment of the façade. Dismantling and repetition of old facade finishing technologies, but using modern materials and other quality, construction work or the use of new technologies on facades - insulation of facades with SFTK systems, curtain facades, reconstruction of facades with changes in the architectural appearance of the building. The type of repair is determined by the condition of the facade and the presence of damage.

Main stages of facade repair

1. Examination of the condition of the facade.

   An important and responsible stage. Damage to the walls is detected. Previous technologies and reasons affecting the quality of operation of the facade are identified, which must be eliminated in the future.

   Project documentation helps to establish the façade technologies used for a particular building, understand the structure of the walls, determine the list of hidden works, and suggest the use of specific materials. Unfortunately, customers often do not have documentation on the construction of facades for one reason or another. Therefore, it is necessary to involve additional expert organizations and research laboratories.

   At this stage, they also check the quality of the roof, drainage systems, parapet covers and ebbs, the work of related organizations (for example, air conditioning), and the work of operating organizations.

2. Determination of technologies, materials and architectural solutions to repair the old façade and create a new one.

   Based on the data from the examination and inspection of the facade, the recommendations of technical specialists, and the requirements of Customers, technologies for repairing the facades of residential and administrative buildings are determined. This could be work to locally eliminate comments, or repeat previous façade repair technologies, but with modern materials by competent construction organization, specializing only in facade repairs. Or the use of new technologies and solutions to create a different architectural facade. Choice low-quality materials, inappropriate technologies, replacement of design solutions, and simply - the lack of competence of construction participants when constructing a new facade or its repair - lead to short term façade services.

3. Repair of house facade

All external wall repair and reconstruction work must be carried out in accordance with approved and agreed upon technical instructions, design solutions, Albums technical solutions and instructions from the material supplier. The entire process of facade work should be reflected in the work production log with marks from inspection services and technical supervision of the customer. Require all participants in the process (including customers) to perform the necessary operations (installation of windows, installation of roofing, parapets, provision of electricity, etc.).

Types of facade systems

Today, two main types of facade systems are widely represented on the market:

• Suspended façade insulation systems – structures with air gap, consisting of cladding (porcelain tiles, composites, fiber cement boards, clinker, etc.) and a substructure that is attached to the wall.
• Plaster heat-insulating facade systems - SFTK (wet facades).

The Bau-group company has been producing facade work and plastering facades since 1998 - our specialization. We have extensive experience in implementing facade repair projects and using modern facade technologies at major renovation sites. We are often invited to rescue and complete work for other contractors when technologies are violated, the quality of work does not meet standards, deadlines are missed and high-quality repairs facade, completion of construction and commissioning of facades. We perform our work efficiently within the agreed time frame and at the agreed cost.

Fast rhythm modern life no delay. Using new materials and technologies that have appeared on construction market, it has become quite feasible to carry out facade works and in winter.

You should not consider the cold season as some kind of obstacle. Cladding the facade of a house in winter will allow you to save time and finish construction earlier. The procedure is as follows:

1) Installation scaffolding. It is performed in the same way as in the summer, without any differences.

2) Installation of a moisture-proof film around the perimeter. It is needed to maintain a stable temperature directly on the external walls.

3) Installation heating devices. For this purpose, devices powered by electricity or gasoline can be used. Heaters that produce soot are absolutely unacceptable, so as not to spoil the appearance of the building.

After installing the film, thanks to heating, the desired microclimate will be formed and it will be possible to carry out repairs at a temperature under the awning of about 5-8 degrees Celsius. In the language of the workers, such a simple structure is called a “heating house.” It provides comfortable conditions for finishing in winter and protects from snow and gusts of wind.

The surface of the walls of the house must be dry, without snow or ice. Work in winter is carried out using special masonry mortars, intended for use in low temperature conditions. Under no circumstances should you prepare the solution using hot water.

Every building needs cosmetic repairs from time to time to update the external appearance of the building, without major intervention in the structure itself. Cosmetic work involves only updating particularly critical parts.

The list of services includes:

• surface preparation - cleaning from dust and complex coatings, eliminating salt and fungal formations;
• restoration of façade surfaces - jointing, filling of cracks, wall putty;
• finishing services - final painting of the facade;
• restoration of architectural elements;
• repair work of the basement;
• repair or replacement of drainage systems, cornices and window sills;
• repair and restoration appearance entrance groups, doors and windows.

Cosmetic repairs are often performed exclusively using the repair method.

A comprehensive renovation involves a complete renovation of the front part of the building. This work is performed only by specialists who are trained in industrial mountaineering. Carried out if total area destruction is more than 30%. This method involves painting and plastering, as well as replacing drainage systems.

Major renovation façade always begins with the preparatory work stage:

1. Complete inspection of the facade;

2. Cleaning all façade surfaces from old coatings;

3. Elimination of salts and fungal formations.

The further progress of the work depends on the task set by the customer. This is either plastering with reinforcement, or putty, or painting or decorative finishing facade.

The basement of the building or even the entire facade can be lined with ceramic or porcelain tiles, marble, granite, wild stone, or wild stone tiles or some other decorative and finishing materials.

The list of services also includes:

• arrangement and restoration of architectural elements of the building;
• repair or replacement of drainage systems, cornices, window sills;
• if necessary, repair, restoration of appearance or replacement of entrance lobbies, doors, windows and stained glass windows.

Restoration of historical buildings - This special kind repair work on the facade of the building, since this very building has a certain historical value. Restoring the facade of a historic house requires a more thorough and thoughtful approach, as well as the use of specially selected materials.

The company "Alpinists", in addition to professionally performing restoration work on historical buildings, provides guarantee for all work performed, as well as post-warranty repairs .

The main enemy when performing facade work in winter is sub-zero temperatures. It negatively affects all work carried out both during “wet” processes and when glazing buildings (when there is a need to open “ warm contour» buildings).

During glazing in winter, there is a high probability that the heating system will defrost and the thermal conditions inside the premises will be disrupted after dismantling the old ones. window designs, doors or stained glass windows. When performing “wet type” façade work, water, which is used in all compositions, begins to freeze at temperatures below +4°C. As a result, compounds that were applied at lower temperatures begin to freeze instead of drying, and this is absolutely unacceptable for high-quality work. To maintain the required temperature conditions, the temperature of the air in contact with the facade must be above +5°C ROUND THE CLOCK.

To comply optimal conditions we create a special thermal circuit. The facade of the building is covered with reinforced polyethylene with ventilation holes, inside temperature regime supported by heat guns that run on gas or diesel fuel.

If openings are opened, we install temporary panels until the translucent structures are installed.

Services from the Mountaineers company mean quality, safety and affordable prices.
