What paint are the facades painted with? How to paint the facade and is it possible to do it. Photo gallery: facade paint manufacturers
only briefly reduced interest in such traditional way finishes, such as painting facades. Everything today more people they prefer to paint the house outside, having previously prepared the base for applying the coloring layer. There's more to learn, what and how to paint a house is now quite available.
Facade paint for exterior is represented by a very wide range.
Painting the house outside is designed to perform at least two functions - to give the facade an attractive appearance and protect it from the harmful effects of the environment. And in both aspects, modern house facade paint provides a very wide range of possibilities.
Painting the facade of a house with your own hands is quite affordable even without serious professional training, of course, if it is not supposed to be painted multi-storey building. So, for example, structural facade paint allows you to even give the facade coating an original and highly artistic look. It is only important to be guided by practical advice how to apply structural paint and follow the instructions for use, which are mandatory on the packaging. 
Particularly careful surface preparation, in particular, requires facade textured paint - the walls must be covered with durable, preferably reinforced plaster and primed. And preference should be given to materials from the same manufacturer, since otherwise the primer may differ too much in composition and not match the paint. It is also important to first familiarize yourself with how to apply textured paint correctly.
Painting the facade with an airbrush (spray gun) has its own specifics. In addition to surface preparation, you need to know:
- what kind of paint can be applied to a particular facade with this generally practical tool
- paint consumption when using a spray gun
- Should the paint be thinned and by how much?
- at what temperature can you paint with a spray gun
- how to care for the spray gun, not allowing the paint to dry in the internal cavities of the tool
- how long does this paint dry under specific weather conditions
So how to paint the facade of the house with your own hands, how practical is it and where should you start?
First, you should decide how the painted house should look like, how important it is to protect the facade surfaces from negative factors. And, based on this, decide what color the paint is purchased, one or more colors. And also if special paint is required.
It can be just a weather-resistant facade paint, a siloxane facade paint with high moisture-proof qualities, a latex facade paint, which also has good weather-resistant and moisture-proof properties.
When choosing a paint for painting the facades of buildings, it is necessary to take into account what the operating conditions of the building are. For example, in regions with frosty winters, the frost resistance of the coating is especially important. It is necessary to take into account the purpose of the structure and the vapor permeability of the paint.
Latex paint, with all its undeniable advantages, will not best solution for painting the building of the sauna or swimming pool.
The properties of the material from which the walls of the house are built must be taken into account when choosing facade paints that can be painted, and when preparing the surface for painting. So, for example, if, then either a vapor-permeable (most often water-soluble) paint should be used, or the plaster outer layer of the facade should be treated with a primer for painting. It is worth noting that good preparation surface also allows, if not to reduce the consumption facade paint per 1m2, then at least do without a significant excess.
As for the quantity, the packages usually indicate either the consumption of paint per 1 m2 of surface, or the approximate area for which one liter should be enough. Thus, in order to calculate the paint consumption for the entire facade, it is necessary to calculate the area to be painted as accurately as possible and, based on this, purchase paint by adding about 10% for possible unforeseen miscalculations, tool failures, etc.
The main difference between facade paints and interior paints is a higher resistance to external influences, low-temperature conditions, high humidity etc. The types of facade paints that exist today not only delight with their quality and variety, but also puzzle with the choice.
Here is an incomplete list, which includes only a few of the most relevant types of paint.
- facade silicone paints. These include silane, organosilicon, siloxane solutions, which are characterized by high hydrophobic (water-repellent) properties. Facade paints based on silicone protect the material of the walls of the house not only from dampness, but also from the growth of microorganisms, as well as pollution.
- Elastic façade paint (rubber façade paint) is one of the modern developments in the field finishing materials. It also has high hydrophobic properties, is resistant to abrasion and creates an attractive and dense layer that protects the surface of the walls. The disadvantages include extremely low vapor permeability. It should be applied to a clean, dry surface at moderate humidity and positive air temperature.
- Front frost-resistant paint on cement base. It has ideal anti-frost properties and vapor permeability, but does not differ in hydrophobicity and a variety of shades. Basically, these are low-key muted tones, gradually losing their intensity under the influence of the environment.
- Lime facade paints for outdoor use. All-weather and resistant to low-temperature influences, also not distinguished by brightness, but vapor-permeable and resistant to the appearance of fungus, mold, etc.
- – modern high-tech facade textured paint based on crushed natural cork, dyed in various colors. Cork coating has certain heat-insulating properties, allows you to eliminate the so-called "cold bridges" that violate the heat-shielding properties of the building when sub-zero temperature on the street. The undoubted texture can be called a plus.
- Silicate paints are also a good answer to the question of how to paint the facade without difficulty and reliably. Chemical reaction securely binds them to the surface, and the characteristics of the material make it possible to counteract microorganisms and the effects of external environment. The disadvantage, in fact, is one: difficulties in repainting. Their improved variety is polysilicon paints - a formula with the addition of silicone resins.
- Acrylic and acrylic-silicone paints based on organic acrylic resin. Positive properties - resistance to abrasion, good decorative qualities, a variety of bright colors, resistance to microorganisms. Negative - low vapor permeability.
In conclusion, you can add ...
Staining, like any facade coating, has its advantages and disadvantages. Moreover, taking into account how many types of special facade paint have appeared on today's market of building and finishing materials, paint moderately high building maybe even non-professional. But since preparation for painting and painting itself is a rather laborious task that requires skills, tools, and sometimes special equipment, in many cases it is better to entrust the exterior decoration of the house to specialists who have necessary experience and equipment.
Without the final stage of painting the facade, whatever the architectural design, the building looks imperfect. The prepared facade of the house for painting is brought to the final stage, when the layer of finishing plaster has dried up and the color scheme has been selected. Painting works are carried out before the onset of frost, which will contribute to the preservation of the plastered walls. The updated facade will protect the house from adverse external influences, noticeably transform and renew it. We offer the secrets of technology and examples of painting the facade of a private house to use them to update your estate or complete construction.
How to prepare the facade for painting?
Any facade paint is specially designed for facade cladding, but the surface to be painted needs careful preparation. If the wall of the house crumbles or has defects, it must be:
- strengthen;
- align;
- cleanse;
- primed;
- impregnated with an antifungal compound.
Not all materials from which external walls are built in private houses require plastering and painting. However, this may be a conscious choice if the entire architectural ensemble of the estate must be kept in a common style and color scheme. External walls are most often made of the following materials:
- wood (log house);
- reinforced concrete panels;
- brickwork;
- shell stone;
- cinder block;
- adobe;
- cast cinder block, etc.
For each material, a certain type of paintwork is selected, which are produced on a different basis.
Exterior finishing and painting is not needed for all surfaces, for example, facing brick with high decorative properties does not require additional staining. The choice of facade paint depends on the material of the walls. Today, the following external surfaces are quite common:
- textured and decorative plaster;
- siding;
- wild stone;
- aluminum glazing;
- metal-plastic facing panels;
- blocks of composite materials and etc.
Attention: Equipment for painting facades depends on the complexity of painting and the number of storeys. In private houses up to the 2nd floor, a stepladder and a ladder are used, and assembly cradles or equipment for industrial mountaineering are needed for processing and painting. In such cases, they turn to specialized companies that are engaged in painting the facade of an apartment building.
The prepared facade is a surface:
- without dents and bumps;
- without crumbling finishing materials;
- flat and dry;
- primed wall and adjacent surfaces.
Tip: When choosing a material for the facade of a house for painting, it is important to be guided not by your own preferences, but general recommendations technology to:
- extend the life of the coating;
- eliminate bald spots and peeling;
- washing off the paint under oblique downpours;
- cracking from temperature changes.
Attention: On combined surfaces, where various building materials were used in the facade decoration, it is often difficult to choose a universal dye that is most suitable for high-quality coverage of all textures. Then you have to seek advice from specialists who must go to the site and give recommendations on the spot. Advice over the phone will not work here!
Often, even the most daring experimenters are not always ready to radically change the facade of the house, although the modern palette of colors for painting the facade of the house is impressive. If we discard our conservatism and prejudices regarding perfect design and look at the illustrations, it is obvious that a black or red house is also beautiful in its own way! For example, painting the facade of the house, photo:
How to choose the right main color and its companions? Take into account simple tips specialists:
1. When painting houses and facades, the color combination should be in harmony with landscape design and decoration of the courtyard at any time of the year. The same shade looks different in winter and summer, on the shaded north side and the south wall open to direct sunlight. The lush vegetation often contrasts with the facade of the house, but the green house looks ridiculous on the snowy plain.
2. Pay attention to the color of the roof when painting the facade of a private house. It is also easy to repaint if necessary, and the roofing material is suitable for this purpose. If the house is waiting new roof, then it is better to match its shade to the color of the renovated facade. It is better if the tone of the roof is darker, but in harmony with the overall finish.
3. The style of architecture is also important to consider, since the classics do not tolerate extremes and liberties.
4. The shade of the walls should emphasize the natural texture as much as possible. wild stone or decorative plaster. The white and cream finishes are in harmony with the white railings and window frames. Dark colors should go well with wild foundation stone, wooden door or boardwalk.
5. The beauty of a smooth façade is in the detailing, and a little contrasting trim never hurts, especially if the building is large.
6. Do not experiment too much with painting individual wall fragments when painting the facade of the house with your own hands, but it is quite appropriate to highlight:
- individual structural details;
- slopes;
- gables;
- pilasters;
- stucco;
- foundation;
- decor elements;
- columns or supports;
- shutters;
- arched fragments;
- front door, etc.
7. Using many shades or colors is undesirable, it may look ridiculous. Classic combination- 3 colors, where the lightest or darkest background, the rest complement the gamut. Also, a lot depends on the proportions of the color, they can lighten or weight the structure.
Tip: You can check the combination of shades on a preliminary sketch - take a picture of the house and try 3-4 options for painting the facade of the house. It's like a child's coloring book. There are also special computer programs where you can play with color. This is the safest and most secure experiment.
How to choose the right type of paint?
To finish the facade, organic and inorganic dyes are used, which have a different structure and chemical composition. It all depends on what surface they are intended for:
- mineral paints for painting the facade of a house fit well on a concrete wall or brickwork;
- modified silicone base revive and strengthen the old facade;
- acrylic paint is suitable for reinforced concrete products and decorative plaster;
- for structures made of wood and metal, universal resin-based paints are selected.
Each paint has its own properties, and some wash out under the slanting rays of showers, others fade in the sun over time. The thermoplastic base softens from overheating, and on some surfaces painted with dispersion paint with north side moss or fungus takes root well. And silicate-sol paint is very reliable, but it is toxic when working with it.
Lime and silicate-based paint has good vapor permeability, that is, it breathes, absorbing and releasing moisture. Other dyes create an elastic glossy film, are immune to water. But from direct sun rays the walls soften, the paint sticks and collects dust on its surface, which is difficult to remove later.
Attention: Modern organosilicon compounds with high vapor permeability repel water, do not erode under the influence of adverse weather factors. They do not form pollution, which is very important when the wall of the house is located along the carriageway of the street.
What complicates the painting of the facade?
When starting to paint the facade of a house with their own hands, a novice ignorant in this matter rarely realizes the scale of the undertaking. Lack of knowledge in wall painting technology, lack of handy tools and devices for moving along the wall, limited budget and lack of experience create difficulties and lead to errors. Because of this, there is a need for new expenses, instead of saving on self-done work.
Attention: Do not rush to complete the work if something fails on one wall. Do correct conclusions or it is much easier to correct mistakes on a small fragment of the facade than to repaint the entire building.
Works on painting external walls require compliance with all technological standards and phased implementation. If facade work is carried out on a prepared wall, after the completion of a season favorable for repair work, in frosty weather or during a downpour, the result will not be what was expected.
Water is a factor that cannot be ignored. It can damage the foundation or basement painted on the outside. A house that does not have a well-thought-out storm drain will undergo a kind of test for water tightness and waterproofing after every heavy rain. The service life of facade paint on such walls can be halved.
A poorly prepared base is another point that is most often missed by “masters” who are ignorant of painting the outer walls. Depending on the region ground water and precipitation can have different levels of acidity. This is also important to consider when choosing a primer paint. It is difficult to check the acid-alkaline environment of the wall, but when water corrodes the facade, it is noticeable. The walls of such houses have to be additionally impregnated and strengthened.
Attention: Any paint ideally lays down only on a primer! Some paints for painting the facade of the house are applied in 1 layer, but 2 standing up looks better. At the same time, the layers should be of different consistency, it is better to make the 2nd one a little thinner, eliminating bald spots and thick strokes.
Preparing the facade for painting
Before applying the primer, it is important to prepare the wall:
- clean from old paint, grease stains, soot and dust;
- wash off stains, dirt and splashes;
- remove rust stains;
- putty marks from nails and minor defects;
- complete the plastering of the walls;
- let the facade dry well.
Tip: Most contaminants can be easily removed from the surface of the façade. wire brush and a small spatula. Sometimes it makes sense to blow the crumbling surface with compressed air, and then plaster it with finishing or textured plaster.
Before applying the primer, the surface of the walls that is too smooth is rubbed with an emery cloth - in a circular motion. Some primers contain fine-grained sand or other suspension - this contributes to better adhesion. For such vertical surface the paint is well distributed and lays down evenly, and does not just flow down, as happens with a perfectly smooth base.
If the plaster has fallen off in some places, it is worth checking all the walls for integrity - knock wooden mallet. The places where there internal cracks and swelling from the fungus, be sure to fall off, sometimes with whole walls. Do not regret it - it would have happened a little later, but after painting. These places will have to be plastered or sealed (clay, cement mortar).
Golden rule: The more carefully preliminary preparation walls, the better the facade painting!
The prepared and primed surface can be painted:
- special paint sprayer;
- household spray gun;
- vacuum cleaner (in the presence of a special kit for painting walls);
- universal industrial machine for outdoor work;
- paint roller and wide brush.
Most dyes are available in special containers of white or cream color, where the coloring pigment is added and mixed well. Before preparing the paint, it is important to study the instructions, where it is indicated, you need to add a solvent, and in what proportion the pigment is added.
Attention: The proportion of pigment and base is very important to observe when adding new portions of paint to the case!
Facade work must be carried out in a respirator and protective work clothes. Hands and feet must also be protected. It is equally important to think about moving along the walls and insurance so as not to fall and not be injured. It is very convenient to work together with an assistant who supplies paint and tools, moves a ladder, cradle, winch and other devices to move along the walls.

Painting the exterior of your home is the easiest way to update the look of your home. Moreover, the color range of paints is not limited to one or two options, but is provided in a wide range of colors. So you can choose suitable option for every design and every taste. 
Since white paints with the addition of color are now popular, you can create a shade yourself. But for facades it is still better to use ready-made options.
The material is applied with a brush or paint sprayer. The paint acts as a protective layer against moisture and dirt. A painted building will last much longer than an unpainted one. The simplicity of the method allows you to significantly save on work. There is no need to hire craftsmen, the cost of which can cost a pretty penny. You don't need any special tools either. All you need is an application tool, the paint itself and a ladder. 
It can be applied to any type of buildings: wooden house, brick, on the walls covered with foam. Any option is possible. Many refuse paint, remembering this pungent smell from Soviet times. But now they have already learned how to make an odorless solution. Absolutely safe and environmentally friendly, not harmful to humans or the environment. 
But, as is the case with any other cladding material, it was not without its drawbacks. The paint does not protect the surface from mechanical damage. Moreover, there may be scratches on it. You can get rid of them only if you paint over.
If the scratch is large, then the whole house will have to be repainted, because if only one wall is painted over, it will differ significantly in color from the rest of the walls.
Another problem with the solution is burnout. Even the most quality material over time on the sunny side will fade. 
And since there are four walls near the house, not all of them face sunny side. And it will burn unevenly. Periodically, you will have to update the layer of the whole house and align it in color.
Since the work is done from the outside, the painting process should be carried out only at the right time, otherwise it will not live long. The best season for coloring is summer.
In spring, the period of flowering and revival of insects, and all this will settle and stick to the newly painted surface. You can use only the quick-drying option.
It is cold in winter and autumn. And the process of painting at cold temperatures is simply impossible. Summer is also worth choosing the time wisely. On a hot day, do not paint the walls. Otherwise, the solution will dry unevenly. The air temperature should not exceed +25 degrees. Before the rain, too, should not be applied material, because because of the water it will begin to flake and crack. Therefore, before you start painting, carefully follow the weather forecasts. 
The quality of the finish depends on the choice of the desired paint. The choice of material for outdoor work is significantly different from the choice for interior decoration. Materials for painting a house must be resistant to all weather conditions: temperature changes, wind, rain. Therefore, the material must be facade works, and in no case for internal.
The sun's rays contribute to the fading of the material. Therefore, the solution should not be afraid of ultraviolet rays. The material must be durable, so it will last much longer.
Various additives in paints will be an additional bonus. Antiseptic additives will increase the protection of the wall from the formation of mold and insects.
This is especially true for wooden houses that insects choose for their homes. Vapor permeability of paint required condition when staining wooden surfaces. And in other options, it would not hurt to buy just such a paint. If the surface of the walls does not breathe, this will cause condensation and, as a result, the formation of fungus and mold. 
Types of paints
Paint on water based the most common option for facade work. By their characteristics they bypass other species. They do not smell and hide small defects surfaces. Most often sold in white with further dilution. Therefore, you need to knead all the paint at once, so that later it does not differ in shade. If you are not sure what you can do, then you can order already ready-made version at the store where you buy it. Water paints are divided into several types. 
Acrylic paints are suitable for all surfaces except limestone. They are cheap and last all weather. She is not afraid of ultraviolet rays, which means that she will retain her color for a long time. Dries quickly, does not smell. And due to its elasticity, it hides some surface imperfections.
Latex paints are famous for their resistance to water. It is pleasant to work with the solution, it is easy to apply, which significantly saves material consumption. It can be applied to any type of surface. However, the paint does not contain antiseptic substances, so you will first need to treat the surface with a primer without fail.
Silicone paint is made on the basis of silicone resins. The paint is elastic and protects from moisture. It is also vapor-permeable, which means that the development of microflora should not be afraid.
Silicate paints have one significant drawback - only silicate-based materials can be applied to them. Otherwise, you will have to get rid of the paint completely. But in other respects, this species is in no way inferior to others. And of the moisture-resistant options, it even has the highest rates of resistance to water. 
Polyvinyl acetate paints are not recommended for painting the facade. They won't stand the conditions. Cement and lime compositions are rarely used for painting the facades of private houses due to the complexity of the work and the specifics of the application.
Organic paints include alkyd and oil solutions. By and large, they are in no way inferior to water, but there is one parameter that repels them from their operation - toxicity. Because of this, the colors emit bad smell, which does not fade for a long time. 
Oil paints are made from drying oil. The paint gradually fades in the sun and if not primed before painting the wall, it will crack. Alkyd paints are more suitable for outer cladding, but their disadvantage is their combustibility. Plus, they fade quickly. 
Preparatory work for painting
Before you start painting, you need to make preparatory work. Inspect the walls for defects. Tap the wall with a hammer to reveal weak points. Old plaster must be removed if it exfoliates and replaced with a new one. 
If there is an old layer of paint on the surface, then you need to get rid of it. You can simply put water pressure on the walls and the weak areas crumble, and then remove the rest with a solvent. If the paint is still okay, then it is quite possible to apply a new layer on the old one. 
If there are cracks, then they also need to be repaired. Slightly expand them and rinse with a jet of water. And cover with plaster. The surface is left until the composition dries completely. To make the material stronger, you can periodically moisten it with water. Protruding frames and elements must be covered with adhesive tape. 
Technology for painting different types of facade
Faster and better work with the paint sprayer. If the house is very large, then this method will allow you to paint the entire perimeter in one day. If the house is not big and you don’t want to buy a spray gun, then you can get by with a roller with a brush. Since you may not have time to paint everything at once, stock up on white spirit, you can soak the brushes in it, and then rinse with water. 
And they will be like new the next day. Pour the paint into the container. If you are working on scaffolding, then a regular paint bath will do, and if you are working on stairs, you can use a small bucket with a handle. For example, from mayonnaise. So it's more convenient to work. The paint is stirred in a bucket. After that, apply it with a brush to the surface. Movement must be in the same direction.
It is best to paint from top to bottom. This avoids the formation of paint drops. And when you get tired, working from below is much easier.
Coloring various surfaces happens the same way. The difference is only in the preparation and choice of paint. The wooden surface will most likely need to be applied with two coats of paint, as it absorbs water well. But on other surfaces it is better to apply two layers. So the color will be brighter, and the protective layer will be thicker. A new layer can only be applied after the old one has dried.
Before applying paint, it is better to cover the walls with a primer. And then apply a layer of varnish on the paint. This is especially true for wooden surfaces. In no case do not leave part of the area unpainted, when the paint dries, the transition will be noticeable. If this is a tree, then paint the plank to the end, and flat surface you need to paint all at once.
Facade painting is traditional exterior finish. It has been used in practice for many decades. In addition, this method outperforms similar ones in terms of accessibility. Any paints and varnishes able to give the house an attractive appearance. Also, painting the facade of the house protects against any environmental influences.
For each type of facade, there is a type of paint that will give additional protection, help to maintain an attractive appearance for many years. It is necessary to understand in advance which type of materials is suitable for work in one case or another, and how to paint the facade of the house with your own hands.
Water based formulations
This is one of the most popular types. They have the following advantages:
- Steam and gas permeability at a sufficient level.
- Elasticity.
- High hiding power.
- Almost complete absence of unpleasant odors during operation.
Most often, manufacturers choose white colors for such paints. For tinting, so-called black pigments are used. This is very convenient if the owner himself plans to choose several shades at once for future work. It is enough to purchase a white base composition along with the pigments themselves, and then simply mix them in sufficient quantities.
But in some cases it is better to immediately prepare the mixture yourself in the right quantities. This is especially true if most of the work in the future is done independently.
Within the group of water-soluble paints for house facades, there are several subspecies.
- Cement.
They must be diluted with water before starting work. Portland cement is a link in the compositions of this variety. It interacts with dyes and polymer additives, due to which a coating is created on the walls. In the future, it will be vapor-permeable, but moisture-resistant and durable, with an attractive appearance.
- Lime.
An excellent option for surfaces that have previously been plastered. Today, such paints are sold either in the form of concentrated pastes, or as ready solutions. The composition of these substances includes antiseptic elements that are necessary to protect against the formation of fungus. Before you start painting the facade of the house with your own hands, lime mixtures are tinted.
- Polyvinyl acetate.
According to the characteristics, it is worse than compositions with acrylic in the base. Paint quickly loses its original properties. It is also about appearance, and operating parameters.
- Silicone.
At the same time vapor-permeable and water-repellent. Solutions are resistant to almost any kind of external influences. They are not subject to chalking, they are able to self-clean. Resistant to the appearance of fungi and mold. After drying of such compositions, you can not worry about the formation of internal stresses. Painting the facade with your own hands will give a guaranteed result.
- silicate.
This type is based on potash liquid glass. They are excellent for covering mineral surfaces such as plastered surfaces, stone and concrete. Separately, it should be said about the resistance to ultraviolet rays. Coatings applied with this material are always highly resistant. Decorating a house is not difficult.
But in this case, you can not do without special preparation of the facade. It will be necessary to prime it, also using a silicate-based solution.
Currently, manufacturers are producing improved types of silicate-based solutions.
About organic-based paints
Oil paints are made using drying oil. A pigment with a coloring ability is added to it. Usually it is itself made from mineral powders, finely ground. Their consistency is such that the substance does not dissolve in the base.
Alkyd compounds are produced using so-called alkyd varnishes. Pigments are added to them along with solvents. Each composition has its own packaging, on which manufacturers write about the destination. For example, there are enamels specifically for work outside or inside buildings. There are also universal varieties.
Choosing paint for certain surfaces
The main thing is to familiarize yourself in advance with the requirements that are created for materials in certain operating conditions when painting facade walls.
You can describe the main criteria that are advised to rely on when choosing.
- The ability to resist the environment.
Dust and moisture, temperature changes are negative factors that require protection. The packaging must contain information about the purpose for external or internal works and taking into account the resistance to external factors.
- Resistance to ultraviolet rays.
The sun's rays provide Negative influence on any surface. If the paint itself is not resistant to moisture, then the destruction process will only worsen. It is best to choose mixtures with special components that provide appropriate properties to those who perform the coloring.
- Strength.
It is necessary to have a certain margin for this characteristic so that the materials do not fail ahead of time.
- Lifetime.
This information is also usually indicated on the packaging. The more it is, the more quality product is in front of the buyer, the better it is to paint with facade paints.
- antiseptic additives.
They are necessary even if already pretreated walls are to be painted.
- Consumption.
Usually they write about what is the consumption for a house of facade paint per 1 square meter. Not only the consistency becomes decisive, but also other parameters such as: quality during preparation, product texture, material application options. Only the average value is written on the package. You can also pay attention to it for those who want to save money.
- Adhesion.
It is determined by the compatibility between the paint and the surface itself, the quality of the preliminary preparation.
- Vapor permeability.
Steam must penetrate through the paint. That is, the wall must "breathe". Otherwise, condensate accumulates inside the rooms and the walls themselves. It doesn't matter what paint the base is treated with.
What can make painting difficult?
Beginners rarely think about how big a task they have to solve. The following are the most common conditions for errors:
- little experience;
- budget restrictions;
- lack of convenient devices;
- technology unknown.
If something did not work out on one wall, do not rush to complete the work. A small painted area is much easier to fix.
All technological standards, phased processing must be observed. More convenient option– use of surfaces with preliminary preparation.
The main factor that cannot be ignored is water. It easily damages basement floors and foundations, even with the use of a coloring agent inside. Homes that lack storm drains. On such walls, the service life of paint materials is halved.
Beginners can also lose sight of surface preparation itself. For each region, water in soils has its own level of acidity. This is also important to consider when choosing the right paint.
Only a primer guarantees perfect adhesion to the paint. Some materials require 1 coat, but look better with two coats. In this case, it is recommended to create layers with different consistency.
On the video: a master class on painting the facade.
Rules for preparing facades for painting
Preparation includes several stages at once:
- First, we clean the surface of formations such as dust and soot, greasy spots, old paint.
- Washing away stains, dirt and old marks.
- Removing rust stains.
- Puttying traces of nails and other defects with small dimensions.
- Completion of plaster work.
- Full drying of the facade.
A metal brush and a small spatula will be enough to deal with most of the dirt on the painted substrate, if they are small. The crumbling surface can be treated with air under pressure.
If the surface is too smooth, then rub it with sandpaper. The presence of fine-grained sand or other suspensions in the primer improves adhesion. Then the paint will be correctly distributed over the entire surface. The more thorough the preliminary preparation, the better the coating will come out later.
