Popular ways to install a wet facade

The design of the facade of the building is as important as its internal execution. Modern manufacturers produce a lot of practical materials that can be used for exterior decoration of houses of any size and layout.

What is behind the name?

Not every homeowner knows exactly what is included in the definition of a “wet facade”. Before proceeding to familiarize yourself with this method of finishing, you should answer this question. The memorable name of the wet facade speaks for itself. In this case, it implies the use of high-quality adhesive solutions in the liquid or semi-liquid state. Thanks to the introduction of this well-thought-out technology, residential premises are reliably protected from the appearance of dew points - with a wet facade they are brought out, and do not penetrate into the ceiling.

In addition, the definition of a wet facade includes three main ways of finishing private houses.in which fasteners insulation, reinforcing mesh and cladding occur with the help of special adhesive mixtures. Even if there is a sharp temperature difference inside and outside the building, disastrous condensate will not accumulate in houses with a wet facade. This technology was released as early as the 60s – 70s of the last century, when the question of efficient energy saving of buildings arose. It is worth noting here that it is the high-quality external insulation of the walls in this case that is the optimal solution, since it makes it possible to move the dew point as far as possible from the interior spaces to the dwelling.

Technology features: pros and cons

Currently, homeowners can choose for themselves the best option for insulation - outdoor or indoor. However, the lion's share of consumers refers to reliable external systems in which the insulation is located outside. Today, many homeowners are turning to this design of the facade of private houses, because it allows to extend the service life of building and facing materials.In this case, as in many others, you first need to prepare a high-quality facade. After that, you can go directly to its insulation with suitable materials. The choice of insulation today is greater than ever, so you can choose the best option for any price.

Only after this, the masters start applying a special adhesive to the insulation material. Following the technology, then it is superimposed reinforcing mesh, resistant to the effects of alkaline compounds. The final stages of all works are plastering the base, as well as the application of the finishing layer of decorative trim. To make a wet facade reliable and durable, it must be a multi-layered cake. This rule should not be neglected, otherwise the lining will be less durable and reliable, and it will be cold inside the dwelling.

Such carefully thought out systems can boast many positive qualities for which many homeowners choose them.

  • One such system combines both a decorative and insulating function, which is very convenient and allows you to save time on additional work.
  • If the walls of the house are too light or thin, then a wet facade is the perfect solution. With such a system, the house will become not only much more attractive, but also much warmer and more comfortable.
  • Using a high-quality warm facade, you can significantly save on heating, since the housing does not require excessive heating.
  • Wet facade is also good because it can be used for any reason.
  • With the help of such a system, it is possible to provide the living space with additional sound insulation.
  • Due to the wet facade, the life of the house will increase significantly, as it will be reliably protected from negative external factors.
  • With a similar design of the house look much neater.
  • Over the years, ugly salt spots do not appear on a wet facade, which is very difficult to get rid of.
  • Overlappings with such a design do not add to themselves, therefore, they do not need to make a reinforced foundation.
  • According to experts, a wet facade is cheaper than its counterparts.
  • In the presence of a wet facade, the inside of the dwelling will be protected not only from frost, but also from high temperatures. The rooms will not be overheated and stuffy.

Today, those technologies are used by those who are accustomed to taking care of their home and want it to maintain an attractive appearance for as long as possible. However, one should not think that a wet facade is a flawless solution, devoid of flaws.

It is worth paying attention to the disadvantages that are inherent in such a system.

  • Many homeowners are upset that the installation of a wet facade can be started only at a temperature of +5 degrees Celsius. Otherwise, all materials may fail at the application stage.
  • In no case can installation work be carried out if it is raining outside the window (even weak and shallow). Yes, and during wet weather installation wet facade is better to move "for later."
  • When performing such a facade, it is necessary to ensure that all construction and facing materials fit together.
  • Direct sunlight falling on a wet facade can lead to excessive drying of the mortar on the floors, which can adversely affect the durability of the lining and its durability and wear.
  • Plastered substrates must be provided with good wind protection.This is due to the fact that in the process of settling dust and dirt may stick to a fresh coating. Type of finish while spoil.

How serious are these disadvantages - everyone decides for himself. However, you will never encounter many of them if you follow the technology of arranging a wet facade. Not the last role is played by the quality of purchased materials. Low-grade solution and adhesive mixtures will not last very long, and their application can cause many difficulties.

"Pie" stuffing

As mentioned above, the prerequisite for high-quality wet facade is a competent device "pie". The composition of the latter includes several important layers, without which reliable coverage will not work. In the role of the base in such a system is a special front wall. It can be any - brick, wooden, monolithic, foam block or sheet. The main requirement that the base must meet is a perfectly flat surface. If we neglect such a condition, air will constantly circulate between the floor surface and the insulation materials, due to which the insulation in the room will not reach the desired level.

The next important layer of the "cake" is the insulating layer. Experts recommend buying nets that are not afraid of contact with alkalis. After the thermal follows a reinforced layer. As a rule, it contains mineral glue and reinforcing mesh. Next, you will need a layer of high-quality facade paint or decorative plaster. It is also allowed to purchase special facade plates of low weight for finishing.

Among other things, it should be borne in mind that the entire "cake" of the wet facade should be waterproof. That is why all materials need to be selected so that each new layer in the direction from the inside to the outside was more vapor proof than the previous one. Only if this requirement is observed, the dwelling will “breathe”. And it should also be borne in mind that the thermal contour of the "cake" must remain uninterrupted. It should not be cracks, holes or cracks.

Types: recommendations for use

A multilayer system called a wet facade is very popular today. It is chosen by many homeowners, however, not all of them know that there are several varieties of such facade design.For a start, it is worth considering in detail which subspecies are divided into wet facades according to the materials used.

  • Organic In such systems, cheap foam will usually act as a heater. As for the reinforcement, it is performed using a special reinforcing mass of organic origin. The final finishing coating in this case is the silicone plaster mixture, although organic plaster can be used instead.
  • Mineral If you decide to turn to the mineral wet facade, then you should purchase high-quality mineral wool for insulation. Reinforcement in such a system occurs with the help of a special reinforcing solution of mineral origin. For the final decorative coating suitable the same material as for organic options.
  • Combined. With such a system, inexpensive foam is also used for insulation. Minerals are used for further finishing.

Modern wet facades differ in the method of fixation.

  • In the heavy version, the insulation does not need to be installed directly on the ceiling.Instead, plates of heat-insulating material are put on dowels, equipped with small hooks. These fasteners are pre-inserted into the wall. In this case, a reliable grid made of metal is placed on the insulation. This element is attached to the special pressure plates. After this, you can proceed to the plastering of the bases and their finishing with a finishing layer of material. With such work it is quite possible to do it yourself.
  • Light facades are much more common. In this version of the finish insulation is attached directly to the walls. For this, it is permissible to use suitable glue together with plastic dowels.

The choice of insulation

One of the main roles in the wet facade is played by properly selected insulation. Today, for this, as a rule, choose either foam sheets (their thickness should be from 5 to 10 cm), or mineral wool of increased density (it is better to take basalt products).

It is necessary to choose the warming material for a wet facade very carefully and carefully.

At the same time, experts recommend paying attention to the following important parameters.

  • Cost With regard to this criterion, then the foam, no doubt, wins the mineral wool. This material has been used for a very long time and is inexpensive, so many consumers choose it, despite its fragility.
  • Vapor permeability properties. Such qualities are inherent in the popular, but expensive mineral wool. According to the professionals, the house “breathes” with such insulation, therefore it is more comfortable to be in it. In addition, "breathing" homes are not subject to the formation of fungus and mold. The foam does not have a special vapor permeability, yielding in this case the mineral wool.
  • The complexity of the installation work. If we compare foam plastic and mineral wool in terms of installation complexity, we can immediately say that the first one is simpler and more pliable. This is due to the rigid structure of the foam.
  • Fireproof. Characteristics of fire safety are also very important for insulation. So, foam plates are combustible, so they must be treated with flame retardants. Basalt wool does not burn. It can withstand temperatures up to +1000 degrees.

And also it is necessary to pay attention to the thickness of the purchased insulation.Today, in stores building and finishing materials, you can meet a lot of insulating materials with different dimensional parameters. The thickness of the plates is different and can be from 25 to 200 mm. As a rule, the pitch in this case is 10 mm.

It should be borne in mind that too thin sheets of insulation may be ineffective. But one should not rush to extremes, because too thick materials are also not recommended to be used, since they only lead to extra money, and in a dwelling with excessive heat insulation will not be very comfortable. Experts strongly recommend purchasing high-quality insulation materials from well-known manufacturers for building facades. Excessive savings can lead to the purchase of low-quality product that will not perform its basic functions and will require replacement, and this is an additional expense.

Materials and tools

To build a high-quality wet facade can and ordinary home wizard. However, for this you need to stock up not only patience, but also all the necessary tools and consumables.All materials and tools should be of unsurpassed quality. It will be much easier to work with such components, and the result will definitely not disappoint.

It is worth considering all the positions that may be useful for such works.

  • You will need a start or base profile. It is necessary to ensure that the parameter of its width corresponds to the thickness of the insulation. The quality of the profile here must correspond to the perimeter of the trimmed floors.
  • It is necessary to get reliable details of connection for a socle profile. Thanks to these components, it is possible to achieve ideally correct joining of all profiles in a single plane. In addition, these components allow you to form the correct joint (temperature gap) between the profiles.
  • Fasteners for frame profiles. It is necessary to ensure that the expansion dowel-nails had a length of not less than 40 mm, if the walls are finished with solid brick or concrete. For ceilings consisting of hollow bricks, it is recommended to choose fasteners of 60 mm, for aerated concrete and gas silicate - 100 mm. It is easy to count the fastener points.If the layer of insulation is 80 mm or more, the pitch will be 300 mm, and with a thickness of less than 80 mm, the installation can be done in increments of 500 mm. At each mounting point will need a spacer washer made of plastic. This part is useful for the most accurate and correct alignment of profiles.
  • It is necessary to purchase high-quality primer to prepare the floor for gluing plates. In this case, for brick, plastered or gas silicate bases, it is recommended to buy a deep penetration primer. Its average consumption is 300 ml per 1 m². For foundations of concrete, it is better to buy a “concrete contact” type soil. The average consumption of such a solution is usually 400 ml per 1 m².
  • It is necessary to purchase high-quality adhesive composition for fixing insulation boards. Choose only those adhesives that are designed specifically for such tasks.
  • It is worth buying high-quality insulating plates with a pre-calculated thickness. Their average consumption, taking into account cutting and possible waste, takes from 1.05 to 1 m².
  • Dowel fungi will also be needed. They are needed for the mechanical strengthening of insulating material. In total, the length of the dowel should correspond to the thickness of the insulation, as well as the length of the spacer element.
  • It will be necessary to stock up on materials for the application of a base reinforcing layer that goes along insulation plates. To do this, most often acquired specialized plaster mixture or a reliable adhesive composition, which is also used for the installation of warm plates.
  • Need to buy a reinforcing mesh. It is recommended to purchase durable and durable products from materials that are not afraid of alkali.
  • Be sure to stock up with water-dispersion primer, decorative plaster and paint specifically for outdoor use.

Preparatory work

When all the necessary components have already been prepared, you should proceed to the next important step - this is preparation of the bases for the future installation of a wet facade.

It is necessary to disassemble this process on the example of fixing insulation for a suitable adhesive composition.

  • Plates of insulation can be attached with glue only if the base is carefully cleaned of all that is unnecessary. For example, if a former paintwork is present on the facade, then it will need to be removed right up to the base itself or the plaster layer.
  • Past plaster is allowed to leave only if it is still in perfect condition. To ascertain this, it is necessary to conduct a thorough check of the base with a light tapping. If unstable areas are found, they should be quickly cleaned.
  • If there is mold or fungus on the walls, they cannot be used to decorate a wet facade. Such defects must be removed from the walls.
  • After the elimination of fungal deposits of the overlap, it is necessary to lubricate with a special “healing” agent. It is allowed to start other works only when the antiseptic on the bases is completely dry.
  • It should be noted that the walls should be smooth. Any irregularities, cracks, cracks and gouges need to be repaired. It is necessary to seal them with primer, sanded.
  • It is necessary to examine the plane of the walls both horizontally and vertically. If deviations exceeding 20 mm were noticed, then they will not be able to level them a little later with the help of plaster, therefore problems should be solved as soon as possible.
  • Pre-install on the walls of the component parts of the metal, which is used for the installation of antennas, gutters, lighting and other similar things.
  • When the repair and plaster layer on the floors dry out completely, the surface must be primed. It is possible to apply soil by means of the roller or a brush. We must try not to lose sight of a single plot on the ground.

Installation and plastering

If the base is prepared correctly, then you can proceed to the installation of starting basement profiles and the further installation of insulation material.

It is worth considering step by step instructions for carrying out these works.

  • Base profile must be set strictly horizontally. It will be installed on it the first plate of insulation. Monitor the evenness of the location of this part should be using a level.
  • You should never set profiles overlap. It will be more correct to mount these parts exclusively end-to-end, maintaining a spacing of 2–3 mm.
  • At the outer and inner corners, the profiles need to be bonded with preservation of the gap. To this end, these details are cut at an angle of 45 degrees.
  • If the density of insulation exceeds 80 cm, then you should take care of temporary stops for mounting the starting profile. These parts must not be bent. After installing the insulation support simply removed.
  • When all the supports are ready, you should proceed to the preparation of the solution. It is necessary to adhere to the instructions indicated on the package.
  • Pour the dry solution into the right amount of water. To bring all the components to a liquid state, you need to use a drill with a nozzle-mixer.
  • Mix the composition should be until a single mass without lumps. As a rule, it takes 5 minutes. Next, you need to make a short pause for 6–8 minutes and mix the solution again.

Adhesive is permissible to lay on the material of insulation in the following ways:

  • strips of 100 mm along the perimeter, leaving 20–30 cm from the edge;
  • small slides with a diameter of about 200 mm, while the height of the applied solution can be 10 or 20 mm.

If the wall being insulated is fairly smooth, then the glue can be applied to its entire surface with a spatula with cloves. It is recommended to apply the adhesive as follows:

  • a small amount of the mixture must be rubbed into the coating of the insulating slab, making a small effort;
  • transfer the required amount of adhesive composition.

Further, the plate, smeared with glue, leans into place and firmly pressed against it.It is necessary to distribute the glue, slightly moving the part to the sides, up and down. Excess glue that comes along the edges should be removed as soon as possible. The next slab of insulation should be placed as close as possible to the previous one, leaving no gaps. If it is impossible without them, then they can be closed with wedges from the mineral wool. As a rule, laying insulation start from one corner, moving on in rows.

At the same time it is necessary to follow the following rules:

  • the initial row must be installed in such a way that it rests against the first profile along the board (limiter);
  • Plates must be laid with a displacement of vertical joints of at least 200 mm;
  • at the corners, use the "gear lock";
  • plate parts close to corners, partitions or slopes should not have a width greater than 200 mm;
  • as soon as possible you need to connect the insulating layer with overlaps and slopes.

Finishing laying insulation, you need to make sure that there are no gaps or gaps left anywhere. All defects must be eliminated with remnants of mineral wool. After laying insulation should install a reinforcing mesh. It is needed for the finishing layer.

Finishing

When the reinforcing layer is completely dry (it takes from 3 to 7 days), you can proceed directly to the finishing of the bases.Apply a thin layer of plaster mixture should be evenly, using a semi-liter in position at an angle. The resulting surface will be the ideal basis for processing reliable facade paint or other selected material. This procedure is the last stage of warming the outer part of the house.

Tips and tricks

When mounting the wet facade, you should follow the advice of experts.

  • For work on the facade you can only use such materials that are not afraid of temperature changes, otherwise as a result you can get a plaster covered with cracks.
  • It should hold a hand on the surface of the base. If there are traces of chalk on it, and something is showered from the wall, then the floors should be cleaned as thoroughly as possible.
  • The base profile after installation should be in line. There should be no gaps or cracks in the joints.
  • Experts strongly do not recommend to choose home insulation fiberglass plates. Such materials can not boast of sufficient strength. Moreover, they are afraid of alkalis, without which plastering and adhesive mixtures are not complete.
  • The heat insulator should not be pressed to the base again. Its offset after a few minutes is also not recommended. If the insulation does not stick as it should, remove the glue solution, and then put it on the plate again and press the part to the surface.
  • In the process of insulating slopes, it is necessary to ensure that the insulating material extends beyond their limits by about 10 mm. With this option to join the main facade insulation will be much easier.
  • During installation, the dowel is considered to be correctly installed, if its head is located in the same plane with the insulating layer.
  • The reinforced mesh can not be laid by installing on a heater that has not been smeared with glue before, because if the reinforcing layer is rather thin, then cracks will appear at the joints.
  • If you decide to do all the work yourself, you should stock up with branded materials and mixtures from well-known manufacturers, despite their cost. It is advisable to purchase products that have good customer feedback.
  • Facade work should be carried out in late winter or early autumn.It is advisable to get acquainted with the weather forecast before proceeding to the design of the facade.

Beautiful examples

A wet facade with a rough peach finish looks impressive on almost any house, from small to large and high-rise. You can dilute the pastel paint with light side panels and a dark roof.

Light coffee facades with white window frames look very tender. In tandem with overlappings of a similar shade, a dark chocolate roof will harmoniously look, as well as a fence made of wood and brick.

Wet facade, decorated with snow-white or cream paint, will look spectacular if you add it inserts under the gray wild stone. Such a building can be decorated with stony paths and wrought iron fences around the site or balcony.

The original wet facade with coffee curbs can be supplemented with stonework at the bottom. On such a house will look organically the roof of burgundy color, which effectively dilute the pastel palettes.

The most common mistakes made during the installation of a wet facade are described in detail in the video.
