Types and subtleties of the choice of facade paint
Facade paints are intended not only to decorate a building, but also to protect the facade from external factors. The walls are exposed to constant negative effects of sunlight, precipitation, sudden temperature changes, as well as the appearance of mold and mildew. That is why experts recommend choosing exclusively high-quality products with optimal characteristics for painting the facade.
Peculiarities
When choosing a paint, be sure to pay attention to the content of binders in the composition. Facade paints contain synthetic resins, but also lime, cement, liquid glass can be included in the composition. The quality of the material depends on the binder.
Cheap paints are distinguished by a small amount of binder. It is often replaced with fillers that increase the volume of paint, but the quality becomes worse from this.
Please note that not all facade paint is suitable for the exterior design of a particular building. Features of the choice of paint depend on the nature of the base. Plaster, silicate, lime, brick, concrete - all these materials require different paints and varnishes.
Properties
Facade paint differs from others in its properties, which is the reason for the popularity of this tool.
Among the characteristic features are the following:
- Waterproof. A layer of paint is used to protect the walls from moisture, which is why the product must have a low absorption capacity. Otherwise, the facade will get wet and dirty. Also, salts are deposited on the walls due to the high level of humidity, and cracks appear. The lower the level of water permeability, the better the paint;
- Wear resistance. Good resistance can be declared when the paint withstands at least 5,000 cleaning cycles until it is completely wiped off;
- Paint consumption. As a rule, this parameter is from 100 to 300 g per 1 sq. m, if staining is done in one layer. For surfaces of different quality, the consumption will also be different.
Facade paints are not used for interior decoration. They are not recommended for use in buildings with high levels of humidity, such as baths and saunas. For cladding such buildings, it is better to use ventilated facades. In order for the paint to adhere better to the facade, the surface must be thoroughly cleaned and then covered with a fungicidal composition.
Views
There are a huge number of types of coloring materials for facades. They differ in quality. Before painting the facade, you need to carefully study the types in order to choose the most suitable material. The most popular are the following varieties:
- Vinyl. When used in finishing works, such water-based paints are diluted with water. The indisputable advantage of this material is its affordable cost, but the quality is far from the best. Often under the influence of chemicals, from mechanical stress, the paint deteriorates. In addition, mold can form on the painted surface;
- Perchlorovinyl. Well protects the surface from moisture. This tool has the following technical characteristics: viscosity - 30-45 s, the material dries no more than a day, paint consumption - 270 g / sq. m;
- Acrylic (latex). They meet all reliability requirements.This material is distinguished by its low water resistance, so the surface will remain intact for a long time, it will not get dirty. The advantages of rubber paints also include the tightness and elasticity of the applied layers. The brightness of the painted surface remains unchanged for many years, such a cladding does not fade under the influence of sunlight;
- Silicone. They are divided into three types: organosilicon, silane, siloxane. Moisture that gets on surfaces painted with silicone paints does not penetrate inside, but simply flows down the walls. Moreover, these materials increase the strength and durability of the facade. Silicone solutions also boast excellent adhesion;
- Calcareous. Such paints must be diluted with water before use. They do not contain organic resins, but there are substances that disinfect the surface. This prevents mold or mildew from forming on the facades. More often than others, white lime paints are found;
- Silicate. They differ in simple composition, durability and wear resistance. On such a surface, fungus and mold are not formed. If you start a renovation, keep in mind that it will be difficult to remove such paint;
- Silicate ash. Silicone resins are added to the composition. Such solutions are easily applied to the surface, they are resistant to high humidity, and have good vapor permeability. Experts recommend using this decorative paint on the facades of buildings covered with dry cement or lime-cement plaster;
- Cement. These materials must be diluted with water before painting. The composition contains a binding element - white Portland cement with polymer additives. Has good vapor permeability;
- Oil. Suitable for painting wood. A characteristic feature is the presence of natural and artificial drying oils and dyes in the composition. In some cases, such paints are used for interior work. They protect the wood from rotting and moisture;
- Dispersive. They are produced on the basis of an aqueous dispersion. They are not resistant to weather conditions and mechanical damage. Such paints and varnishes are not at all popular, since they do not prevent the appearance of mold and mildew.
Decorating the facade with some paint is a great solution. This will make the surface brighter and more "lively".
Various colors can be combined. Textured paint is often used, with which you can create an original pattern.
Criterias of choice
Before buying a paint and varnish material, you need to carefully study all its characteristics in order to choose the best one. Most buyers pay attention only to decorative properties and completely forget about other parameters. The durability and quality of the paint depends on the following characteristics:
- Lightfastness. This factor is important, because under the influence of sunlight, many paints lose their attractive appearance. Do not choose too bright colors, as muted tones are more resistant to fading. Particularly stable dyes have a special marking on the packaging, which allows you to quickly select the appropriate material;
- Water vapor permeability. This property of the coating means its ability to transmit water vapor. The minimum moisture allows the coating to adhere better, retaining its rich shade for many years. Some manufacturers produce paints that allow fumes to pass only from the inside to the outside;
- Resistant to flaking and blistering. These characteristics are related to the adhesion of the coating to the façade. In this case, much attention must be paid to cleaning the surface, as well as adhering to the staining technology;
- Resistance to negative environmental influences;
- Abrasion resistance. This factor determines the number of cleaning and cleaning cycles that the paint can withstand. The type of cleaning is also taken into account: dry or wet.The higher the value, the better the product, the longer it will last. This property is determined by laboratory research.
Compliance with the above criteria, as well as the high quality of the material, must be confirmed by certificates. When choosing a topcoat, it is imperative to take into account the technical characteristics, for example: consumption, drying speed, thixotropy, hiding power. These properties are indicated on the bank, so that they are always available for review.
Also, do not forget that not all paints are universal. So, for some surfaces, only specific paints and varnishes are suitable. For example, for finishing a facade made of stone, it is worth using cement-lime coatings.
Manufacturers
Everyone knows that paints of the same composition of various brands have their own quality features, so you should familiarize yourself with the lines of facade paints from well-known manufacturers:
- Caparol. A feature of this material is its thermoplasticity and low water absorption. Thanks to these properties, dirt will not remain on the facade;
- Alpina. A product with high adhesion, excellent hiding power and wear resistance. It is easy to apply to the facade. To give this paint the desired shade, it is necessary to use colors produced by the same company;
- "Olympus". This company offers products based on acrylic with quartz filler. Paints from this brand can be used for painting both interior and exterior walls. They are appropriate for use in rooms with high traffic, as well as with high mechanical stress;
- "Lacra". One of the best facade paints, which contains a synthetic polymer that does not react to water. Thanks to this, the product is evenly applied to the surface. The paint contains water. The composition can be used indoors and outdoors with high mechanical stress;
- "Tex". Differs in high quality. The paint adheres perfectly to the surface, allows air to pass through, and is resistant to high humidity. Mold and mildew will not form on the painted facade. Over time, the paint does not fade, and even after many years the color will remain saturated. Moreover, the material is resistant to severe frost;
- Terraco. Matt acrylic paint, which is very popular. It hides all surface defects, is elastic, and the wall covered with it is easy to clean. These products are resistant to alkaline environments. Its indisputable advantage is the excellent ratio of high quality and affordable price;
- Ceresit. Water-based paints that are odorless. They allow the walls to "breathe" and also protect them from mold and mildew. This material is a versatile material: it can be used on almost all surfaces. It is also worth noting its resistance to low temperatures;
- Akrial. A paint and varnish product that has received a huge number of positive reviews. This is an acrylic enamel designed for use in difficult climatic conditions, for example: at low temperatures, high humidity. Distinctive characteristics of the material are that it is possible to paint the surface in frost, as well as vapor permeability, resistance to sunlight;
- "Dali". It is used for painting buildings that require frequent renewal of the facade paint layer due to heavy dirt. This tool can be used at temperatures from -40 to +40 degrees. It is odorless, UV-resistant and durable.
Decide on the characteristics that are important to you and choose the best facade product.
If you are at a loss with the choice, then contact the specialists, because the facade is a "visiting card" of any building, so it must be well-groomed.
Consumption
If you plan to paint a large area, then it is best to buy the material with a margin, taking into account the consumption per 1 sq. m. Products from one manufacturer will definitely be the same shades. If you do not have enough money, you should not buy paint from another company - you may not guess with the color. As a result, the facade will look ridiculous.
To calculate the required amount of material, you need to multiply the height of the wall by its width, and then subtract the area of the sections that will not be painted. As you know, all values need to be rounded, and in this case it is necessary to do it upwards.
Note that more paint will be needed for a rough surface. Material consumption for such walls is 15-20% more.
Also, the consumption is influenced by such nuances as the type of surface to be treated and the hiding power of the composition. The manufacturer indicates the information on the last property on the bank.
Paint consumption is:
- for painting flat non-absorbent surfaces - from 6 to 8 sq. m per kg;
- for coloring an absorbent surface with defects - from 5 to 7 sq. m per kg.
Water-based paint is in demand today. When painted in two layers, its consumption is about 300 g per 1 sq. m. One layer will dry for about an hour. In addition, such paints are odorless, and you can easily clean the surface of them.
The consumption of oil paints directly depends on the color: the lighter the product, the more material will be needed.
On average, consumption reaches 200 g per 1 sq. m. Alkyd paints, if necessary, must be diluted with turpentine or white spirit. Any surface can be painted with this material, even metal. The consumption of this composition depends on the color and texture of the surface, as well as on the method of painting. On average, the consumption rate is 150 g per 1 sq. m. A wide range of paints with different characteristics allows you to choose the optimal agent for painting houses and public buildings.
Subtleties of application
Surface painting is a complex process that requires the utmost care. If there is old paint on the walls and it is in good condition, then it does not need to be washed off - you can apply a new layer on it. But, if the old material has already cracked and began to crumble, it will be necessary to thoroughly clean the walls. Before starting to paint, check if the walls are ready to paint. To do this, use a block of wood.
Swipe it over the surface: if there are traces of shavings, then you can start painting. If you find any defects, then they definitely need to be putty.
When all flaws have been eliminated, the surface must be checked for its ability to absorb moisture. To do this, run a damp sponge along the wall. If the trail immediately disappeared, then the wall must be primed. When you start applying paint, divide the entire wall into several sections beforehand. They can be separated by pipes, bends, protrusions, and the like. It is convenient to apply paints and varnishes using a roller with up and down movements. It is more convenient to use a brush in hard-to-reach places.
When one area is already painted, there is no need to wait until the entire surface is dry. Start painting another. There will be no difference in overlaying layers. Note that the direction in which the paint is applied depends on how many coats of paint you plan to apply. For example, if there are only two layers, then the first is best applied horizontally, and the second - vertically.
If three layers are planned, then first and at the end they are painted vertically, and the second layer is applied horizontally.
Can I paint indoors?
The modern construction market offers a huge selection of facade paints. Some of them can be used for indoor work.
When interior decoration, you need to pay attention to the composition of the material:
- Binders. Acrylic and silicone paints can be used to paint interior walls.For their manufacture, synthetic resin is used, due to which the material has high quality and excellent characteristics;
- Waterproof. Note that the higher the number, the better. Especially this factor must be taken into account if you plan to paint the walls in the bathroom, kitchen or sauna;
- Wear resistance. Acrylic paints can boast of this property. After painting the surface with this material, a high density layer is created. As a result, the walls become resistant to various mechanical influences. The facade of the building will remain bright and attractive for many years.
The stores offer paints and varnishes that dry as quickly as possible. Considering all of the above characteristics, we can conclude that acrylic and silicone paints are suitable for painting walls indoors.
Examples of painting facades
Often, even those who like to experiment are not ready to radically change the facade of the house. Most people prefer calm pastel colors. The modern palette of available colors surprises, allowing everyone to make all their dreams come true. The combination of beige and black shades looks luxurious. These two noble colors will allow you to create an aristocratic design.
To create a beautiful facade of a house, consider the recommendations of experts when choosing a shade:
- The color of the facade should be in harmony with the landscape at different times of the year. The same tone will look different in winter and summer. For example, a house painted in green shades will look ridiculous when it snows outside;
- When changing the facade of the house, do not forget to paint the roof as well. It should be several shades darker, while in harmony with the exterior;
- Observe a uniform style on your site, take into account even the smallest nuances;
- Looks spectacular when the walls emphasize the natural texture of wild stone or decorative plaster. The beige finish is in perfect harmony with the white railings and window frames. Dark colors go well with wild foundation stone, wooden door or terrace;
- If the house is large, then pastel colors can be "diluted" with bright details, for example: slopes, window frames, shutters and the like;
- The ideal number of exterior colors to use is three. A landscape that is too colorful will look ridiculous.
In addition to your own interests, fashion trends should also be taken into account. Today, natural dark tones are in demand: brown, dark brown, black. Many people try to avoid black shades, but in vain. This color makes the appearance more noble and respectable. Black is great for painting wooden houses with large windows or verandas.
To create your dream home, you need to choose the right color in accordance with the architectural features of the building. Shades of the same color, differing in saturation, look beautiful. It is appropriate to use natural tones.
If you want to visually enlarge the building, then light shades are an excellent choice, and those who want to emphasize simple and concise forms should choose rich colors. When choosing a color palette, they use the following principle: the basement is the darkest element of the house, the roof is painted with a slightly lighter shade, the facade is medium in saturation. Do not forget to observe the combination of different tones of the same color.
Wooden houses are worthy of special attention. Their feature is environmental friendliness, so natural colors will look best. Green, red and brown wooden houses can often be found.
In order to emphasize the woody texture, experts recommend using transparent enamels that perform protective functions while maintaining structural features.
There are more than enough types of paints. Please note that there are no perfect paints and varnishes.It is necessary to choose products taking into account the operating conditions, as well as the type of facade. If you want not just to paint the surface, but to create some kind of ornament, choose a textured paint. This is the best alternative to decorative plasters. With the right choice of paint and varnish products, you can create a high-quality, durable and durable facade coating.
