Exterior paint (paint and varnish material - LKM) is intended both for protection and decoration of the building at the same time. Today's market can offer the user a wide range of its colors, with different consistency and specialization in a narrow area of facade work. Usually, exterior coatings are used to finish already plastered facades, but modern samples are already able to process a poorly prepared surface, perfectly lying on wood, concrete or brick. In any case, the choice of coloring material for exterior decoration will largely depend on the natural conditions of the area where the object of work is located.

The compositions under consideration are particularly durable, they are resistant to the manifestation of external influences, are characterized by vapor permeability and elasticity. Their minimum service life is 10 years. The facade coloring material is made in such a way that it can evenly be applied even to complex-shaped bases, but most samples from the middle price segment are preferable to be applied to a pre-plastered surface.
Facade paints must perform the following functions:
The composition of the considered coatings includes various binders, fillers and solvents, suspensions and hardeners. All of them form the main technical parameters of the mixture and determine the direction in a narrow specialization in the field of application. The main mandatory parameters include:
They are categorized according to their structure. The determining component, as a rule, becomes the type of solvent. Thus, two large groups are water-soluble and organic-soluble coatings.
This type is used for painting brick/concrete substrates, and they can also be used on facades that are finished with lime. The basis of the structure of such mixtures is liquid glass or silicate glue. The advantages include resistance to mechanical stress, successful resistance to dirt deposition, UV protection and a long service life.
This type of material is produced on the basis of drying oil and contains protective inclusions along with coloring pigments. Oil-based materials are rarely used today for exterior decoration, due to their outdated and very weak protective properties.
These paints are almost universal and can be used both outside and inside structures. Most often they are made on a water basis, they are distinguished by good qualities in terms of adhesion (adhesion to the base), resistant to premature abrasion and excessive contamination.
Such material is rightfully considered the most popular among all exterior paints. It can perfectly protect the treated surface, has good weather resistance, and has a long service life. It is applied very simply, it comes in sufficient containers at an adequate price.Most acrylic paints are water-based, although there are some samples made on the basis of organic solvents.
These paints have a highly specialized decorative purpose and are used to cover relief walls (for example, made in the Baroque style). They contain a variety of fillers that allow you to apply the substance to brick, concrete, wood, plaster. Moreover, they are especially unpretentious to the level of preparation of the painted surface. Their use is allowed on the bases, replete with small cracks and chips.
In order to ensure that the facade parts of buildings retain their appearance for a long time, the paint for their coating should be selected based on the material that was used during construction. The table below reflects the ratio of the capabilities of paintwork materials and building bases:
IMPORTANT! For long-term preservation of the cleanliness of the facade, it is preferable to use self-cleaning mixtures. They are made on silicone bases and pigments that have been processed with synthetic polymers. The greater the percentage of resins present in their structure, the easier the treated surface will be cleaned. In extreme cases, the final washing of such facades can be done manually using plain water.
On plastered bases, facade mixtures retain well and even improve overall integrity. As a rule, they work on plaster with water-based acrylic, silicone / silicate compounds. Such paints do not have a pronounced unpleasant odor. The layer formed by them leaves open pores in the plaster, which ensures unhindered removal of moisture from its surface. Among other things, the plastered surface will be properly protected from the negative effects of weather conditions, the occurrence of fungus and mold, and the formation of the smallest cracks. The applied layer will last at least more than ten years.
Water-based acrylic paints are usually used for this type of exterior walls. They easily provide the wall with adequate protection against temperature changes, contribute to the filling of the smallest cracks, while completely preserving the concrete structure for a long period of time. Also, water-soluble compositions can be used for concrete, in which the base component is acrylic resin and its copolymers. However, before applying such coatings, the surface will require preparatory work, namely the application of a primer. In order to increase the service life of the painted surface up to 20 years, it is preferable to cover the concrete with two layers of paint. A two-layer coating will help increase protection against mechanical stress, prevent the damaging effects of various chemicals, and also provide good moisture and weather resistance.
Oddly enough, outdated oil formulations will become optimal for wooden facades. In their structure, they contain astringent, coloring and protective inclusions, which penetrate very well into wood surfaces, firmly fixing there. For oil coatings, the main advantage is their low cost. Nevertheless, the tree from the outside can also be finished with modern types of alkyd compounds, which have the following advantages:
At the same time, it is worth mentioning that acrylic substances will increase the environmental friendliness of wood and increase its wear resistance.
The materials used to cover brick facades are simply required to have an increased level of adhesion, as well as breathability, while adequately protecting the brick surface from ultraviolet radiation and weather precipitation. For such requirements, silicate samples are the ideal choice. It is always worth remembering that the brick is laid using a solution containing alkali, which can burn through a fragile coating. Thus, the super-strength qualities of brick paint, in terms of interaction with alkaline substances, are extremely important.
For painting metal objects, mixtures should be used that will not only decorate the surface, but also protect it from corrosion and the negative effects of moisture. Also, the mixture must have the qualities of fire resistance and heat resistance. For example, oil and alkyd materials can withstand temperatures up to +80 degrees Celsius, and individual acrylic and epoxy mixtures up to +120 degrees. The compositions created on the basis of silicone resins will freely restrain the temperature effect of +600 degrees Celsius. It is worth noting that for metal facades it is even allowed to use oil-based coloring materials, but they will not cope well with the effects of water, which is why their use on this front of work is not very successful (except perhaps only for arid regions).
Acrylic variations are considered the classic choice for metal processing today, which will allow the protected surface to “breathe”. However, acrylic is extremely weak in resisting low temperatures, which is why the coating will quickly lose its original external presentability. It is allowed to re-apply alkyd layers on top of each other, which are able to tolerate the negative effects of the environment well, have an increased degree of adhesion, and can give the surface an attractive sheen of a glossy shade. The disadvantages of alkyd include only high toxicity, which does not play a big role in outdoor conditions (but the staining process should be carried out exclusively with the use of personal protective equipment).
IMPORTANT! Professionals do not recommend the use of so-called universal coatings, which are positioned as "suitable for all types of facades." Practice shows that they have unimportant technical characteristics and have a short service life. It is preferable to use a specific type of paint for a specific surface.
Coloring materials for outdoor work are designed to "preserve" the treated surface, creating a reliable layer of protection on it. This layer should not absorb water, but should repel it, because permanent contact of snow / rain with the wall will necessarily (over time) lead to the destruction of the cladding or the formation of cracks in the erected monolith. At the same time, indicators of heat resistance and frost resistance are important for street paint. Such a finish is simply obliged to withstand multiple freeze-thaw and heating cycles.The presence in the mixture of inclusions in the form of UV filters will not allow the color of the cladding to fade and will slow down its overall fading. It must always be remembered that mineral pigments are better able to withstand sunlight than organic ones.
Important parameters also include vapor permeability, whose sufficient indicator for facade use starts from 130 grams per cubic meter. Here it is necessary to make a reservation that if waterproofed metal structures act as a facade, then vapor permeability will not be important. Antiseptic additives will also contribute to the safety of the treated base, because they will not allow mold and fungi to develop. And the presence in the composition of additives that improve the level of resistance to mechanical stress will add additional “points” to the selected coloring composition.
It is always important that the chosen shade of the facade decoration of the building harmonizes well with the surroundings, neighboring buildings, without getting out of the general picture with the ridiculous colors of windows, roofs and walls (unless this is the purpose of the artistic design). Modern manufacturers offer their customers such an extensive range of colors that it becomes difficult to choose just one. Thus, during the purchase, you must follow a few simple rules:
