The consumption rate of facade paint per 1m2 for plaster (acrylic, bark beetle, etc.)

Advantages

Among them, there is a whole list of various reasons that force building owners to give preference to it:

  • extending the life of the building;
  • low weight;
  • the ability to align roughness;
  • protection from natural conditions;
  • thermal insulation properties;
  • small labor costs for application;
  • optimal price;
  • a wide range of products, etc.

Facade plaster protects walls from aggressive and unfavorable climatic factors, which significantly increases the service life of the building itself.


Facade plaster

Since this material is applied to the walls in a fairly small layer, it does not exert significant stress on them. Therefore, do not worry that the effect of plaster on the load-bearing parts of the building will have a negative effect.

Perfectly even walls are not needed for facade plaster, since it itself is a material that can level them a little. With the help of facade plaster, you can hide some of the flaws, roughness and flaws of previous work on the facade of the building.

Thanks to this, home owners will be able to feel comfortable enough in them, as well as save on heating when they need it. Sometimes, due to the fact that the plaster mixture is vapor-permeable, it is compared to ventilated facades, since it does not allow condensation to accumulate on the surfaces of buildings.

The application of facade plaster is quite simple and easy. This work is quickly performed and does not require significant labor costs. That is why the cost of finishing a house with such material is not very high. Many people in the country can afford it.

If you wish, after the completion of the plastering work, the facade itself can be painted in any color with facade paint.


Application

It is also important to note the protection of the facade wall plaster from some mechanical damage. First of all, this applies to light damage that falls on it, and not directly on the building itself.

A good builder knows many ways to apply any of the materials to the walls, so you can create the perfect finishing solution for the building.

It should be noted that there is no better or worse plaster for the facade. Each of them has specific properties and is suitable for specific homes. The choice must be made based on those parameters that are of greater importance for the building.

Features of use for facades

The mirror surface of the facade is achieved
due to coating with transparent varnish. Additionally, the surface is polished. Glossy
the effect of the composition is expressed by 5-10%. The applied layer must dry 100%
(other layers dry on average ½ day).
Failure to comply with the rule leads to the appearance of visual imperfections and
defects. Complex works on finishing the facade are carried out by the composition,
intended for painting plaster (painting). Dilute acrylic
facade paint, if it is thick according to the instructions on the package.

Consumption for 1 m2

90% consumption per 1 m2 - no more than 0.5 l, at
economical consumption - 0.2 liters. Departures from the norm depend on the number of layers
in the process of staining. Smooth and even, without distortions and grooves of the surface
reduce the indicator to 0.2-0.3 liters, porous and embossed require 0.3-0.5 liters of paint.

Composition and structure of acrylic paint

All binders are present and
adhesion enhancing substances. Colors (pigments with a specific color that help
in the formation of tone or shade) are included in all types - the exception is white
dye. To create the desired viscosity, the composition contains solvents, they
also control the density. Fillers add functionality. Supplements differ and depend on
purpose of the composition. The structure is homogeneous. It can be thick or runny. Acrylate
paint is used to color wood in 90%, as it allows you to pass
air.

Roller selection

The drum is fluffy or made of foam. He
helps to achieve an even application over the surface. Artwork
require the use of a tool with removable nozzles. Foam rubber with large
cells leaves bubbles. The pile of the main area is 6-18 mm.

Facade wood paints "Teknos" for outdoor use

Wood is a traditional, convenient, environmentally friendly building material. In the natural environment, the tree grows and resists natural adversity for decades. Becoming a board, a bar, a log, it darkens, cracks, loses strength. In such circumstances, exterior paint for exterior woodwork is the only effective protection against material aging, loss of attractiveness and strength.

What negative factors affect a wooden house

To paraphrase a famous song, we can say that nature does not have good weather for wood:

  • sunlight in the infrared and UV ranges is fraught with cracking, peeling of fibers, loss of natural color;
  • fluctuations in positive and negative temperatures destroy the structure due to cyclic compression and expansion;
  • high humidity leads to swelling and the appearance of mold;
  • dryness, heat dry out the wood, cause resinification in conifers.

In swampy areas, facade paints for wooden houses protect from putrefactive processes, in industrial areas - from man-made pollution. The destruction of the bearing and facing elements by wood-boring beetles is prevented by special additives in the coloring compositions.

Requirements for facade wood paints

Paints and varnishes preserve the wood to maintain its original characteristics. The goal is achieved using various formulations. The following requirements remain common for oil, alkyd, acrylic paints for wooden facades:

  • high moisture resistance and lack of permeability from the outside due to a dense elastic film on the surface;
  • protection against mold, fungus, bugs, insects, microorganisms;
  • reducing the intensity of ultraviolet radiation;
  • dirt-repellent properties;
  • sufficient mechanical strength to external influences;
  • frost resistance and invariability of characteristics with daily and seasonal temperature fluctuations;
  • vapor permeability to preserve the natural breathability of wood.

The most important aesthetic requirements for facade paints are distinct texture, good color rendering, and a wide range of shades. The time until the next painting is at least 5-10 years.

Types and selection of Teknos wood facade paint products

When choosing a paint, take into account the conditions of use, the type of wood, the type of lumber. Only then are they determined with a color from the existing palette of shades. For painted surfaces, products are purchased that are combined with previously used ones. So water-dispersion coatings are incompatible with solvent-borne paints and varnishes. Wintol oil-alkyd paint is suitable exclusively for old coatings of the same type or unpainted surfaces: external walls, platbands, window frames.

Water-borne acrylic paints for wooden facades

The Teknos catalog contains mainly water-soluble products that are absolutely safe for humans and the environment.High elasticity, vapor permeability, a wide range of saturated colors from the Teknomix palette are common features of all acrylic paints and varnishes.

Nordica - a series of paints Matt, Primer,>

Alkyd paints

Covering water-soluble antiseptics Visa and Visa Premium are combined products containing alkyds and acrylates. Tinted in the same color palette as Nordica paints, but leaving the wood grain visible. They form a durable waterproof film (semi-matte, glossy) while maintaining air exchange. Used on board and log surfaces. They are distinguished by a long interval between repair coats.

Antiseptics and oils for wood

The basis for reliable wood protection is the initial antiseptic treatment and impregnation with oils with deep penetration of biocidal components. For these purposes, Teknos has developed the Woodex and Woodex Aqua lines of organo- and water-soluble paints and varnishes. Products are used to impregnate planed surfaces and logs before finishing painting, and in a tinted version - to protect them from ultraviolet radiation. The color is chosen according to the map of glazing shades or a palette for external surfaces.

For the correct choice of wood facade paint for outdoor use, see the documentation on the website and consult with our managers.

Facade paints

First of all, it should be clarified what qualities the facade concrete paint should have.

In this case, the requirements will be slightly higher than for the main types of paintwork materials, since:

  • firstly, the work is carried out outside;
  • secondly, concrete itself has special requirements.

Material properties for outdoor use:

  1. Perhaps the main requirement for facade decoration is resistance to high humidity and water itself: natural precipitation in the form of rain or snow.
  2. An equally important property of paint for outdoor use is resistance to temperature fluctuations. Even if the surface is not exposed to direct sunlight, the wall heats up during the day and cools down at night. In addition, the paint must tolerate seasonal temperature changes well.
  3. Color stability. Paintwork materials should calmly tolerate the action of ultraviolet radiation, while not changing color, chemical or physical characteristics.
  4. The coating must have good anti-vandal characteristics, be impervious to the effects of various chemically active substances, and withstand mechanical stress.
  5. The paint must be non-flammable. Fire safety of facades is a fundamental requirement for the commissioning of a building.

Colored concrete coating must have a high degree of stability to ultraviolet radiation and atmospheric precipitation

These requirements apply to any facade finishing material.

At the same time, concrete walls add additional characteristics to the list of required characteristics, including:

High degree of adhesion

Poor adhesion to concrete will quickly lead to delamination of the decorative layer and a violation of the integrity of the protective film.
Facade concrete paint must have a high vapor permeability to prevent the accumulation of condensation inside the concrete wall.
The paint and varnish materials should include antibacterial additives in order to avoid the formation of mold on concrete surfaces.
When painting concrete, it is important to strengthen the anti-corrosion protection of the metal reinforcement inside the walls .. Summing up, we can say that paintwork materials for concrete for outdoor use must have high resistance to abrasion and create a fairly strong protective film to prevent the impact of negative factors directly on concrete

Summing up, we can say that paintwork materials for concrete for outdoor use must have high abrasion resistance and create a fairly strong protective film in order to prevent the impact of negative factors directly on concrete.

With the help of staining, you can turn a boring gray concrete facade into an interesting design solution.

Classification of paints for outdoor use

Facade paints are divided into several types, depending on the production method and the quality of the resulting surface.

Solvent

By type of solvent:

  • water dispersible or diluted with water;
  • solvent or based on another organic solvent: white spirit, xylene.

This factor is very important, since water-dispersion compositions can be used only with a positive (plus) value of the air temperature indicator. Solvent paints and varnishes can be used at low temperatures, but at the same time they have a strong unpleasant odor, are toxic and fire hazardous.

Texture

According to the quality of the resulting surface, paints are divided into textured and smooth. Textured paints make it possible to obtain very interesting surfaces with unique architectural solutions. A smooth surface is not as interesting, but it still provides a stronger and denser protective coating.

Possibilities of painting a concrete facade with textured compositions

Colour

Depending on the forming agent, concrete paints have a different color palette. At the same time, almost any paint of the same type allows you to mix compositions of different colors to obtain the desired shade. Also, the surface obtained by painting can have different reflectivity.

According to this property, paintwork materials are divided into:

  • matte,
  • semi-matte,
  • glossy.

Modern paintwork materials have a very rich color palette.

Selection Tips

To choose a suitable facade paint, it is worth considering a number of factors, starting from what kind of work the dye is intended for. If you mistakenly choose a paint for interior work, such a coating will quickly become unusable due to the lack of powerful protective properties. The compatibility of the type of facade paint and the type of coating directly determines the durability of the finishing work. For example, acrylic varieties work well on concrete, brick and wood surfaces.

It is important to take into account the operational characteristics of the dye

If there is no ductility, cracking is likely to form over the entire surface during hardening and shrinkage.
The paint should not contain toxic components that can cause an allergic reaction.
It is worth paying attention to the drying time, temperature and humidity requirements when performing finishing work.
The storage conditions of the facade paint and its shelf life are important.

When choosing a composition, you should pay attention to the protective properties. It is necessary to take into account the environmental factors that characterize the region, as well as resistance to mechanical stress (shock, abrasion, vibration) and the level of moisture resistance

If the coating does not allow air to pass through, the walls will accumulate moisture and damp, becoming unusable (it will be stuffy in the house, a specific smell will appear). The biological inertness of the composition is relevant for areas with high humidity.

In addition, it is worth paying attention to other aspects.

  • Resistance to ultraviolet rays (a particularly important parameter for southern sunny regions, affects the color fading and the integrity of the painted surface).
  • Resistance to drop, minimum and maximum temperature indicators.
  • Resistant to aggressive weather conditions (rain, snow, hail, frost, strong wind).
  • Fire safety of the composition.
  • Resistant to various chemical compounds used to clean the facade or present in the atmosphere due to emissions from a particular plant.
  • Presence of antistatic properties (especially important for houses near roads, where dust from passing cars is a constant phenomenon).

It is worth paying attention to the aesthetic qualities of the facade paint and the warranty period.Whatever the properties of the facade paint, if it is intended for 10 years of service, like enamel paint, for repairs designed for 20 years, it will not work

Types of heaters

Very often, many people who are building their house, the question arises, which insulation is better for the facade under the plaster. Hardware stores offer several options that suit everyone in one way or another, but at the same time have several differences.

Depending on these differences, it is necessary to choose the material as insulation under the plaster facade of the house.

Mineral insulation systems

A distinctive feature of mineral insulation systems is their vapor permeability. In addition to this property, they are non-combustible material and have a fairly high strength index.

Unlike polymer boards, mineral boards are somewhat heavier and can absorb a small amount of liquid, even though they are treated with special water-repellent compounds.


Mineral insulation

For uneven facades, it is best to use two-layer products. Their upper layer is more rigid and dense, while the lower inner layer is soft and easily adheres to the unevenness of the wall surface.

In order for mineral panels, just like facade plaster, to work in addition to each other, only vapor-permeable materials must be used. This will allow the walls to "breathe", which will make the ventilation in the house quite good.

Polystyrene foam insulation systems

Distinctive features of expanded polystyrene, popularly referred to as polystyrene, are its light weight, ease of use, and water resistance. It does not get wet at all and water cannot destroy it.

It is best to use boards with high strength. The ideal option is a material treated with fire retardants, since the foam itself tends to burn and melt. With this additive, this property of this polymer is significantly reduced, since it self-extinguishes when exposed to fire.


Styrofoam insulation

This will not help if the fire spreads from an external source, but self-burning stops within four seconds.

This is important due to the fact that the foam during the melting process emit a large amount of toxic substances that affect people in the building.

There is also a type of extruded polystyrene foam, which has better properties, but more expensive. When used in facade systems as insulation, it is the best material.

Which insulation is better

If the materials are highly vapor-permeable and have low thermal conductivity, it is better to use exactly the same insulation - mineral. This applies primarily to timber frame and walls made of large-porous expanded clay concrete.

If the outer walls were made of sufficiently heat-conducting materials, such as bricks, concrete blocks, slag and expanded clay concrete, both expanded polystyrene and mineral insulation panels can be used.

House facade decoration

After the walls are leveled and the insulation is closed, you can start applying textured coatings. Consider common textures:

Bark beetle. With the help of plaster, the surface of a tree worn out by insects is imitated. The composition of ready-made mixtures "bark beetle" includes mineral grains (for example, marble) with a size of 2 mm. When leveling the mortar on the wall, the rounded grains leave grooves. The direction can be arbitrary, as you like.

Fur coat, Lamb, Shagreen. These textures are also quite simple to create with your own hands - just roll them over a fresh layer of plaster. If a trowel is used, then it is pressed against the wall and pulled back, leaving a rough surface.When working with a cement-sand mixture, you can use a broom or a coarse brush to spray the mortar over the wall. A pneumatic bucket is often used to cover large areas.

Kameshkovaya. It is created with a ready-made plaster consisting of mineral chips and a binder base. The size of the stones is 1.5-2.5 mm. The mixture must be applied to the wall and leveled with a trowel.

Imitation of masonry. Much depends on the skill of the master and the methods of work. The material can be a cement-sand mortar both in pure form and with the addition of fine mineral grains. The stone surface of the façade blends well with the smooth sections of the walls. Often only the basement of the building is trimmed under the stone.

Let's summarize

Facade plastering is one of the simplest and most attractive finishing methods available even to inexperienced builders. A large selection of colors and textures allows you to choose the appropriate option to your taste. All types of facades are available for finishing - brick, concrete and wood.

Varieties of paints and varnishes for painting facades

Each type of paint intended for painting a facade contains an adhesive, color additives and a solvent. In addition to the mandatory components, manufacturers of paints and varnishes are trying to supplement the composition with something special in order to emphasize the originality of the product. Such an addition can be both the technology of ease of application and reliable protection from the external environment. In this case, the basic difference is the content of the sticky substance in the composition.

Acrylic facade paint

Paints and varnishes based on acrylic additives are the most common and popular types of dyes for the facade of the house. These paints have an adhesive called acrylic polymer. It allows you to protect plastered walls from weather and natural influences. In addition, the coloring of acrylic-based products is easy to change, so you won't have any problems with tinting.

Acrylic-based facade paints for home are either organic or with the presence of a solvent (water-dispersed, white spirit).

Organic paints are intended for use in cold seasons, even at low temperatures, as they have the property of fast curing. They come in both glossy and matte types.

Water-based paints have good adhesion to the plastered coating and do not have an unpleasant odor. In addition, they have a fairly low cost compared to other types of paints.

Silicate facade paint

This option is suitable if the facade is planned to be painted in light color shades and without textured coating. Liquefied glass, alkali-resistant additives and calcium borate act as an adhesive in silicate paint. They are designed to penetrate plaster and create internal protection by gluing any cracks. But this tightness does not allow steam to pass through, which is a disadvantage. The application of such a paint implies a good treatment of the plastered surface. In addition, silicate-based paint lacks a wide range of colors, as it contains chemicals.

Silicone facade paint

Silicone-based paint is the most modern type of facade paint, which has incorporated the main advantages of other types of paint and varnish products. It contains silicone resins, which create a reliable water-repellent coating on plaster, the consumption of which is well correlated with the technological properties of analog solutions.

Silicone paint has excellent adhesion even to rough surfaces, including chemical coatings. At the same time, the dried paint does not absorb moisture, but tends to let steam through at almost the same level as that of silicate paints. Its elastic characteristics allow it to bond even wide cracks, which will never unstick under the influence of high temperature, in contrast to acrylic and latex analogs.

Despite the high cost, silicone-based paint is in demand in the field of facade finishing. The reason for this is ease of application, lack of odor and safety for humans.

Other types of facade paints

PVC paint has also found its niche in the market due to its low cost. It has a fairly bright color palette. In addition, the facade can be painted with perchlorovinyl paints and varnishes during the cold season. It protects the surface of the walls from corrosive effects and atmospheric precipitation, showing high resistance to biological and chemical threats.

The disadvantage is that it is easily flammable due to its chemical basis, it is quite toxic and has an unpleasant odor. In addition, PVC dye is short-lived, with a maximum service life of 4 years.

To give the facade an additional decorative effect, many people use structural facade paints, since they have a thick consistency due to the presence of plasticizers in the composition. This type of paint is used as an alternative to decorative plaster.

Paints are divided into a large number of types, so the choice must be made with an orientation to material capabilities and taste preferences.
