Facade paint on decorative plaster. Facade paint on plaster - characteristics, types, features
If the facade of the house is finished with plaster, it not only looks beautiful, but also protects the walls from outdoor atmospheric and biological phenomena. For the durability of such protection, it is necessary to properly process the coating of the facade walls. With the help of facade paint on plaster, you can simultaneously give the surface an aesthetic appearance and practicality.
Competent selection of paint for the facade
As you know, the exterior decoration of the house is influenced by various natural phenomena, including rain, snow, frost, humidity and even the ultraviolet rays of the sun.
In this case, it is necessary to take into account the temperature of the air flow constantly affecting the surface of the facade, not to mention the dust and dirt that remains on the walls. When talking about biological threats, it must be remembered that the surface of the walls of the house is exposed to moss, mold, fungus and harmful insects.
This is not all, but the main reasons for the adverse effect on the walls of the house from the outside. Therefore, it is necessary to choose the right facade paint for the plaster and correctly cover the walls. Below is a list of how to paint the front surface of a house:
- roller;
- putty knife;
- paint sprayer;
- a set of brushes;
- solvent;
- sandpaper.
So, for reliable protection of facade walls, paint must meet the following requirements: performance characteristics, technological bases and decorative features.
Performance characteristics
First of all, paint with performance characteristics must be sufficiently resistant to external environmental influences, while not losing its properties under the influence of frost, heat, air flow and humidity, which manifests itself as a result of precipitation.
In this regard, the facade paint is divided into 2 types: weather-resistant and limited-resistant.
When purchasing a dye for, it is necessary to pay attention precisely to the weather resistance of the products offered, since this option is the only correct choice that can provide reliable protection of the wall surface.
Weatherproof paints provide vapor permeability to the plastered walls of the house. This is necessary so that the condensate remaining on the surface of the facade can evaporate into the air, otherwise it will begin to collect under an impervious coating, which will lead to the appearance of bulges, and ultimately to external damage to the walls.
This property can be revealed by paying attention to the sponginess of the applied layer. It depends on the type of binder in the content of paints and varnishes.
In addition to steam permeability, performance must include resistance to exposure to sunlight, which can damage the painted layer. In addition, this paint will not fade in the sun and will always look like freshly applied.
An important quality is the increased adhesion. This property makes it possible to ensure high-quality adhesion of the dye substances with the facade plaster. With its help, swelling and bulging of uneven areas of plastered walls are prevented. But it is worth remembering that no paint will provide high-quality adhesion to walls that are poorly prepared for its application.
This is what paint applied to the facade looks like /
At the same time, paint for outdoor use must be water-repellent so that the walls do not absorb moisture. This will protect the facade from the formation and development of moss, fungus, and harmful bacteria. It does not hurt to pay attention to the resistance to mechanical damage, that is, the dried paint should not crumble or scratch with accidental contact.
Technological fundamentals
The technology of high-quality painting is based on the convenience of applying paints and varnishes. Painting of facades requires the thinnest coating layer, since a thick layer tends to chip off after a certain amount of time. Therefore, facade paint for a home should have the property of not being absorbed into the plaster and retaining its colors even with light application. In addition, it will help save on paint and varnish materials and prevent you from problems with drips that can form due to drips.
Facade paint acquires its protective characteristics only after it dries. Accordingly, it should have a drying quality in a short period. This will allow you to paint the facade even at the most inappropriate time of the year, for example, in the pre-winter period. As a result, the painting technology largely depends on the properties of the paint and varnish products themselves.
Decorative features
The paint must be susceptible to discoloration using special colors designed to match the desired color. Also, the painted facade of the house must have reflective properties, that is, the dried dye must repel the ultraviolet rays of the sun and prevent contamination of the facade coating. According to their decorative features, paints are conventionally divided into 3 types: glossy, semi-gloss and matte.
Glossy paint works well on elements such as window openings, doors and façade details. This is due to the fact that under the rays of the sun, the glossy effect creates glare, due to which unevenly processed sections of the facade are noticeable. But at the same time, such paint is easier to wet clean and has increased resistance to weathering. However, glossy painting is not recommended for uniform areas of the exterior walls of the house. It is better to paint the front area with matte paints, as they hide possible defects in the plaster coating.
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 a sticky substance 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.
With all the environmental advantages of acrylic paint, mold or mildew cannot form on it.
Acrylic-based facade paints for home are either organic or with the presence of a solvent (water-dispersed, white spirit).
Organic paints are designed 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 bonding any cracks. But this tightness does not allow steam to pass through, which is a disadvantage. The application of such paint implies a good treatment of the plastered surface. In addition, silicate-based paint does not have 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 that 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 on 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, unlike acrylic and latex analogues.
Despite the high cost, silicone-based paint is in demand in the field of facade decoration. The reason for this is ease of application, lack of odor and safety for humans.
Other types of facade paints
Vinyl perchloric paint also found its niche in the market due to its low cost. It has a fairly bright color palette. In addition, painting the facade with perchlorovinyl paints and varnishes can be carried out in the cold season. It protects the wall surface from corrosive effects and precipitation, showing high resistance to biological and chemical threats.
The disadvantage is that it is highly 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 additional decorativeness, 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 subdivided into a large number of types, so the choice must be made with an orientation to material capabilities and taste preferences.
Plaster is one of the most popular finishing methods both indoors and outdoors, but, often, it needs finishing in order to give aesthetics and protect the leveling layer from the effects of an external aggressive environment.
In this article, we will make an overview of which is the best exterior plaster paint for outdoor use, and which composition should be used for indoor decoration. We will analyze the main stages of the technology for painting plaster layers of different compositions, talk about the manual and mesh method of surface coating and analyze the consumption of materials.
Exterior paint on plaster - main tasks
Here the question is relevant: why does facade paint for plaster for outdoor use stand out in a separate category? The answer lies in difficult operating conditions. So, materials for painting the plaster of building facades must be resistant to the effects of external aggressive environments:
For a high-quality result, a well-prepared plaster of walls for painting is required
Types of paints for outdoor plastering
The market of finishing materials is replete with offers of paints, here it is important to understand that they have a different base, and, depending on the composition, have their own characteristics. Let's figure out the components and on this basis we can conclude which of the paints for plaster for outdoor use most fully meets the requirements stated above.
Silicate based
Silicate facade paint on plaster is a base made of silicate glue (liquid glass), to which mineral pigments and fillers are added. The composition guarantees a durable and strong outdoor coating, inert to UV and chemical impurities in precipitation, does not lose its attractiveness for about two decades. It has excellent vapor-permeable characteristics, the facade will breathe, ventilate, and as a result, it does not threaten to get damp. vapor permeable: the wall will not get wet under the painted layer. The disadvantages of silicate-based paint on plaster are low resistance to mechanical stress, abrasion, it is not elastic, which leads to cracking.
The structure of silicone paint formed by different tools
Lime
The lime-based paint is based on slaked lime. This is the most budgetary option for finishing the plaster outside and this plays an important role when choosing. But having saved on the purchase, in the future, significant financial investments will be required, the fact is that the paint gets dirty, washed off by rain, you will have to renovate the walls once a year. Although this material cannot be called practical, it has bactericidal properties and a high degree of vapor permeability, with the correct technology for finishing the facade, mold and mildew will not form on it. The color range is limited to white and pastel shades, of course, you can add bright pigments, but such paint for the facade of a house on plaster will quickly fade in the sun, the finish will lose its visual appeal.
Cement base
Painting the facade over plaster with cement paint has the same features as the lime material. The mineral base is white Portland cement, different colors are added to the palette. In relation to limestone competitors, cement-based paint for exterior plastering is weather-resistant, but does not have bactericidal properties. Despite the very low price of the material, it is rarely used in individual construction.
Acrylic facade paints for plaster
Acrylic paints for plastering are at the peak of popularity, today it is the optimal combination of high quality and a pleasant price. But here too there are pitfalls, the acrylic composition has poor vapor permeability, but this disadvantage is more than compensated for by low hygroscopicity, resistance to mechanical damage. Acrylic paints are divided into two types: water-based and organic-solvent, the latter is an excellent solution for difficult work, including painting external walls on plaster with high wear. Consumption 0.5-0.7 l per m 2.
Acrylic lays down smoothly, without a pronounced texture
Silicone
At the moment, silicone-based paints are recognized as the best of the whole range of proposals. The plaster layer becomes hydrophobic, does not absorb precipitation and dew, but at the same time high vapor permeability rates remain, the walls breathe and do not get damp. Silicone paint for plaster has good adhesion and hiding power, it does not fade by UV rays, is not afraid of frost and heat, does not attract dust. Usually, these are water-based compositions, they are somewhat inferior to acrylic in terms of resistance to abrasion and elasticity. The consumption of facade paint for 1m 2 for plaster is 0.1-0.15 liters.
There are also structured latex paints, to which plasticizers are added, thick, after application in appearance - this is a textured finish, a good alternative to decorative plasters, according to the method of applying a fur coat type.
Technology for painting plaster on facades
It is better to paint large areas mechanically, using a spray gun, you can do it with a roller on a long stick, but the work will take much longer. You will also need:
- the woods;
- brush to rub the nodules and paint over hard-to-reach places;
- grooved paint tray for wringing out brushes and rollers.
Training
If the surfaces were previously painted, you should peel off the weak layers, fill in the potholes. It is also necessary to check the compatibility of the existing layer and the new material.
Compatibility table
The next stage - we treat the surfaces with an impregnating, antiseptic primer, then a covering, this will increase the adhesion of the paint to the surface. The walls should be smooth, even, run your hand, there should be no grains and dust on the palm.
Good to know: An opaque gray primer is suitable for all types of paint. For whites and pastels - light, for bright ones - dark.Painting external walls over lime-cement plaster requires additional filler. It is recommended to make a putty layer with fiberglass reinforcement, nylon mesh. After drying, the layer is sanded, cleaned of dust, primed and you can start painting.
We paint the plastered facade with our own hands
We mix the paint, it is better to do this with a mixer. To save material, you can mix the paint for the first layer with the primer gel. If the plaster is smooth, the paint is applied with uniform strokes, it is rubbed well along the edges slightly diagonally, the next strokes are performed with an approach to the previous ones, which will avoid more saturated stripes at the joints. The second layer is applied only after the first one has completely dried. It is recommended to use a thick paint for better coverage. Almost all paints, except for water dispersion ones, are designed for 2 application layers. But if you are not satisfied with the result, thin the paint to a liquid consistency and apply 3 coats.
Painting of decorative plaster with a pronounced texture, such as rain, begins with working out all the grooves with a brush. And only after that the main layer is applied. If you start painting the embossed plaster with a continuous layer, painting cannot be avoided, and additional strokes in the protrusions will noticeably differ in color.
Interior paint for plaster
For finishing plaster indoors, acrylic, silicate, silicone, water dispersion, lime and even oil paints are used - the whole range of bases, as well as for outdoor works, but other additives are added to them. But such painting of decorative plaster with your own hands is good if the texture does not require additional touches. The rating is headed by materials based on acrylic, then water-based, in bathrooms - silicate and silicone. Often, it looks simple, without chic, the interior seems impersonal.
Blurring is a great way to visually change the geometry of a room.
Manufacturers have responded to the needs of modern design, and today you can buy decorative paint with various effects - this is a great opportunity to apply a structural pattern to smooth, even walls and ceilings.
Let's talk about the most popular ones:
- Multi-effect - various plastic, colored additives are added to the white paint, the compositions are applied alternately, through masking tape.
- Antique walls (aging) - first the base is applied, then the patina is rubbed.
Plaster coating with aging effect - relevant for modern interiors
- Craquelure - two-component mixtures, the first layer is background, the second is decorative, cracking is achieved thanks to hardeners.
- Metallized coatings are an ideal solution for modern styles: gold, bronze, flat, silver, etc., used for accents in combination with conventional paints, applied with a semi-dry sponge.
Various metallic effects on smooth plaster
- Natural, natural surfaces - painting of walls after plastering with compositions with small inclusions: sand, stone dust, fragments of shells, fibers.
- The effects of northern lights, mother-of-pearl, pearls, chameleon are achieved by applying a protective layer of varnish with special components to the paint.
Important: Material consumption depends on the degree of hiding power and color, as well as on the thoroughness of surface preparation, for example, the consumption of oil paint per 1 m 2 for plaster can vary significantly: 1 kg of white is enough for 7-10 m 2, and black or bright for 15 m 2. Specify the data in the instructions on the package.
Technique for applying paint to plaster indoors
We clean the surfaces from dust, greasy stains, dirt. If necessary, putty, grease. Apply a deep penetration primer, let it dry. Paint for decorative plaster is usually applied in 2, sometimes in 3 layers. First, you need to paint over all the embossed places with a roller with a long pile or a brush, then you can apply the main covering layer.
If you apply a few tones darker to the protruding parts of the relief using the dry brush technique, the wall will visually become more voluminous. To reduce contrasts and smooth out borders, the upper dark layer should be rubbed with a rubber roller or a regular glove.
Decorative, textured paint with the effect of Venetian plaster
Metallic effects are best applied with a sponge. A roller with a short, hard pile achieves the effect of a bark beetle over a thick layer of paint. To get the blur effect, you must first apply a light tone, then a darker one, wait for it to dry and, as it were, rub it with a damp cloth.
Exterior finishing is an important component of construction, and every owner wants to get a beautiful and tidy home, but at the same time save money on finishing materials. Painting the facade over plaster is the cheapest and easiest way to improve the exterior of a building. Even a person inexperienced in painting science can cope with such work, and in today's article you will learn how to choose facade paint and apply it to the walls.
Not any paint is suitable for painting facades. Before deciding on the color and cost of the material, it is necessary to understand that there is building paint for internal and external work. In our case, compounds for outdoor work are needed, since any others are not able to withstand specific operating conditions: temperature and humidity drops, exposure to ultraviolet radiation, etc. Ordinary paint will simply peel off after the first rain or crack with the onset of frost, and work will have to start over.
So, we need paint for outdoor work, but there are also some nuances here. For example, different formulations can differ in the range of temperature stability. So, if you live in the south, where summers are very dry and hot, it is better to choose a paint that can withstand high temperatures and will not fade in direct sunlight. If we are talking about a house in the northern region, frost-resistant paint is needed.
You should also make a choice based on the material of the walls. For example, to paint the facade of a house made of foam blocks without plaster, you will need a good moisture-resistant paint that can mask irregularities and minor cracks on the surface. For concrete walls, a different paint is needed. Usually, professional builders follow one simple rule - what kind of plaster, such is the paint. This means that if the plaster is based on silicone, then you need silicone paint for it, and if you used acrylic plaster for the facade, then you need to take acrylic paint. Otherwise, materials that are different in nature can conflict, leading to premature destruction of the building.
For a better understanding of the specifics of the choice of paints for the facade for plaster, we suggest considering the properties of various compositions:
Most often, builders choose facade paint for acrylic-based plaster, since it is inexpensive, durable and easy to use.
Calculation of the amount of paint
So, if you have decided on the type of paint for plaster, it's time to calculate how much it will be needed for the entire facade. To do this, pay attention to the packaging of the selected paint - it always indicates the consumption in liters per square meter of surface in one layer. In some cases, it can be written the other way around - how many square meters of surface can be covered with a liter of this paint.
Manufacturers often write the consumption of the composition in a certain interval like 0.1-0.25 l / m². A lower consumption figure here means painting smooth surfaces, and a large one - rough or unprimed walls.
To save your time, you can go to the website of the manufacturer of the selected paint and look for an online calculator there for calculating the number of cans depending on the area of \u200b\u200bthe facade. Usually there you need to enter data on the type of surface and its square, after which the calculator will automatically calculate the amount of paint.
To find out the amount of paint yourself, you need to multiply the area of \u200b\u200bthe painted surface in square meters by the paint consumption, then multiply the resulting number by 2, since you need to apply two layers and add a safety factor of 1.1. When buying any building materials, you need to take a little more than the estimated amount, just in case.
It is clear that painting wooden facades, brick or concrete walls will take a long time, and therefore the paint needs to be stored somewhere. To do this, choose a shaded and dry place. Packages should not be exposed to direct sunlight, they should be protected from frost (temperatures can vary from + 5C to + 27C, for detailed storage conditions, see the package). If you opened a new can and saw that the paint has stratified, that is, there is a transparent liquid on the surface, and the pigment has settled a little lower, mix it thoroughly with a stick or a construction mixer. This is completely normal and a well-mixed paint will fully meet the stated specifications.
Paint application
The durability and quality of the exterior finish is directly influenced by the thorough preparation of the substrate before painting. Facade plaster for painting must match the pigment used and vice versa. This will provide better adhesion and wear resistance. Any plaster should be pre-primed. In this case, the primer will serve as additional protection against moisture and will seal the base.
If you are working on an old wall, check the condition of the plaster layer. Severely cracked plaster should be removed and cleaned. This can be done with a strong pressure of water or by hand with a stiff metal brush and spatula. If you notice areas of accumulation of moss or mold, clean them and treat them with an antiseptic. If you don’t do this and just paint the wall with fresh paint, after a while mold or moss will grow back and destroy the finish from the inside. All cracks, holes and chips in the wall should be sealed with putty. The same applies to areas with peeling plaster.
To determine how strong the wall of the house is, and whether it needs strengthening and new plastering, glue a piece of ordinary transparent tape to the surface, smooth it well and tear it off with a sharp motion. If pieces of the wall remain on the adhesive tape, then the base is fragile, and it needs to be strengthened - to clean off the old plaster and apply a new one. If the tape remains relatively clean, you can start priming and painting.
Facade plaster painting technology boils down to the following:
- The newly plastered facade should be left to dry for 30-60 days (the period depends on weather conditions, the thickness of the plaster layer and the characteristics of the plaster itself).
- Apply a primer. If you are working with an unplastered sand-lime brick house, the walls can be coated with a colorless protective primer and then painted. However, regardless of whether there is plaster on the facade or not, it must be primed.
- Facade painting.
The only material that is better not to be painted is facing ceramic bricks. But this is not because the paint will not stick to it - it's just that such a material itself is quite beautiful and self-sufficient. If you are working with a new baked brick house, it is best to plaster and paint the facade as soon as possible so that efflorescence does not appear on the surface of the brick wall.
Wall priming
Many people do not understand or underestimate the importance of a primer before painting a wall. The primer composition works as follows: it penetrates a few centimeters deep into the wall and solidifies there, filling in microcracks and forming a protective film on the surface. Thus, the wall material becomes denser, stronger and better adheres to the paint. Since all cracks and pores of the wall material are filled with primer, the surface becomes smoother and less moisture absorbing. Moisture is contained in any paint, and if the base is too porous, it will quickly absorb, and you will need several times more paint.
The primer significantly reduces the consumption of facade paint by blocking pores and cracks in the plaster and wall. Its cost is much lower than that of the cheapest facade paint. The choice of a primer should be based on the coloring composition used. This information is usually found on the packaging. Ideally, you should use a primer and paint from the same manufacturer.
Helpful Hint: To improve the quality of the paint, use a primer of the same tone as the exterior paint. In some cases, instead of a primer, you can use the exterior paint itself, diluted with water in a 1: 1 ratio.
After priming the surface, leave it to dry for 1-2 days.
Tool selection
As you can imagine, painting the facade is a very laborious undertaking, and a narrow paint brush is clearly not enough here. However, the choice of tool for applying primer and paint depends on the consistency (degree of viscosity) of the composition, as well as the characteristics of the surface texture and your skills in this area.
The most common tools are brushes and a roller. If you are working with fairly smooth walls, choose short-nap tools. The roller is much more convenient in this regard and will allow you to finish the job faster with less paint consumption. You may need a brush to paint hard-to-reach places, for example, near doorways, behind pipes, near a window sill, etc. If you're working with textured plaster, use a wide, long-bristled paint brush.
A few words about spray guns. These devices allow you to quickly paint large areas, but the consumption of dye increases significantly. Spray guns are convenient to work on embossed surfaces, but this will require a little practice. There is nothing complicated in the work, it is only important to understand how to control air pressure and learn how to handle the tool. It will take an hour of your time and some paint. It is important to choose the correct viscosity of the paint and the diameter of the spray nozzle - if the paint is too thick and the nozzle is too small, it will simply clog.
Painting technology
When you have prepared the paint on the plaster for the facade of the house, primer and tools, you can get to work. If you're painting the walls of a low-rise building, you'll need a stepladder. However, constantly rearranging the ladder is very inconvenient and tedious, therefore, ideally, it is necessary to build scaffolding (made of planks or rent from a specialized company). For houses with 3 floors and above, equipment for high-rise work is already needed. This is associated with a certain risk, and therefore it makes sense to entrust the work to specialists. Alternatively, you can paint the first two floors yourself, and entrust the work at a height to an employee.
Painting technology:
- The day before work, check the weather forecast - on the day of painting and a couple of days after it should be dry and moderately warm weather. If there is a wind, cooling to + 5C and below. Rain or fog, outdoor finishes are best set aside.
- Remove dust and dirt from the surface with a wire brush.
- Apply a primer and let it dry completely.
- Cover all parts of the facade that should not be painted (windows, slopes, blind areas, etc.) with polyethylene or masking tape.
- Apply the first coat of paint to the wall, being careful not to take long breaks from work. It is better to work here with several hands so that there is no difference in color shades and streaks.
- Apply the second layer of paint after the first one has completely dried. Drying time depends on the composition of the paint and is indicated by the manufacturer on the packaging.
Helpful hint: To avoid washing the paintbrush or roller from the paint every time during breaks, wrap them in a plastic bag - this will prevent the paint from drying out.
Painting facades with plaster is not only one of the cheapest and easiest ways to get a beautiful and original home. Correctly selected and well-applied paint will provide additional protection against moisture and extend the life of the walls of the house.
Plaster is an integral part of any facade, and it also remains in construction. However, for all its functional qualities, it looks rather unsightly outwardly, remaining a gray and ugly mass. And to correct this defect will help painting the facades with plaster, which will immediately give the whole building a bright and interesting appearance.
All about paints
Interestingly, speaking of facade painting materials, one can emphasize not only the color change that they carry for the exterior, but also positive practical points for the walls of any structure.
After all, high-quality paint for facade work on plaster allows you to preserve and increase all the positive aspects of the plaster layer, and these include:
- Strengthening the moisture resistance of the walls, which always has a positive effect on the duration of the structure's operation.
- Hygroscopicity. The material does not close the pores of the base of the walls of the house, therefore, steam removal from the premises to the outside functions normally.
- The paint coat adds extra durability to the finish and is weather resistant.
- Enhances the tolerance of the finish to temperature changes, increasing the frost resistance indicators.
- Counteracting the spread of fungi and microorganisms on the facade surface.
Important! The colors of the facade paint on plaster, thanks to a special technology for making the color scheme, do not fade in sunlight, and the exterior design will be presented in bright colors for a long time.
Types
All main types of facade paint can be roughly divided into three types:
- Silicone.
- Acrylic.
- Silicate.
Moreover, each type has its own distinctive advantages.
So, for example, in acrylic and silicone paints, it can be noted:
- The almost complete absence of pungent odors, because the material is simply based on water.
- Painting can be carried out in already functioning premises, and not only at the end of construction and finishing work.
- The service life of acrylic paint for outdoor use is about 10 years, and silicone paint is 2.5 times longer.
Important! The silicate paint is based on liquid glass, therefore it is recommended to work with it with greater care. But the silicate base of the material copes well with the appearance of small cracks on the walls.
From the point of view of appearance, after application, the facade paint Bark beetle on plaster looks interesting. It is obtained in the form of eaten bark of a tree, from which its name comes, but in practice, there is simply a small grain in the paintwork material, which is responsible for the effect of the bark beetle.
Application
Naturally, the instruction for painting external walls always presupposes the complete completion of the main construction and installation work at the facility. That is, the roof should already be installed, windows and doors installed, slopes and window sills made, all the necessary communications carried out.
There are also requirements for weather conditions and they must be met:
- The air temperature should be stably positive.
- The average daily temperature at the time of work should not be lower than 10 C.
- Do not apply paint during or after rain.
- The wall surface must be completely dry.
- It is not recommended to apply paint in hot weather, especially in direct sunlight.
Training
Preparation can begin by calculating the required amount of material. It is necessary to understand that increasing the consumption of facade paint on plaster can only be "hindered" by respect for the material and the correct calculation of the area.
On average, 1m2 of plaster can take up to 300 grams of paint, respectively, 1 liter is enough for an average of 3-5 square meters. An important clarification must be made here at once, we are talking about the consumption when applying one layer! Accordingly, with the second or third layer, the flow rate will increase.
Naturally, paint is always purchased with a margin. The price of the entire facade increases from this, but the moment of getting into the color is important here, because if the paint ends at the wrong time, it will be quite difficult to get into the color and it will be too clearly noticeable on the facade.
After calculating the estimate, you can start preparing the surface. For this, the plaster is cleaned of dirt and dust. If there are oil stains on the walls, they must be removed without fail. Over time, oil will definitely penetrate any finish.
If there are obvious defects, they can be corrected with your own hands with cement mortars or glue, after all, the paint will not hide everything.
Once all primers are dry, which is a few hours, paint can be applied.
Paint application
Facade painting technology on plaster involves three options for applying material to the wall surface:
- A simple brush. The method is suitable for a small area, plus the presence of forests is necessary if we are talking about a private two-story house.
- Roller. The most common method.
- Spray gun. With this method, paint is simply sprayed in a thin layer over the surface.
This is not to say that there is a best or most suitable technique, each method has its own advantages.
In terms of coloring rules, the following can be noted:
- It is recommended to apply all material at one time and without long interruptions.
- Painting goes from top to bottom to eliminate drips and drips on the finished surface.
- Paint application The bark beetle is carried out, and the grains in the material are responsible for the “eaten bark” effect.
Output
Everything is good in facade paint, from practical use to appearance. The incredible ease of application () is also a huge plus.
All the positive qualities of the material will be shown in the video in this article, and together with the qualities it will be possible to "spy" on the practical use of paint.
