Exterior and interior decoration of premises with paints and varnishes is the most affordable and simple design option. Paints are presented in a wide range, they have different characteristics and properties. Popular with consumers and interior designers latex paint, whose qualities help to create indoor optimal microclimate without a specific smell and release of toxic substances. What are the advantages of this material?
Interestingly, latex began to be used in ancient Egypt. Somewhat later, materials began to be used in painting and icon painting, and only in the 19th century did they find wide application in construction. What is latex paint? Synthetic latex - water-dispersion material, in which particles of a substance are contained in a liquid dispersion. The color of latex-based paint is given by special pasty colors - they are added to the composition to obtain the desired shade.
Features and benefits of latex paint:
If the painted surface needs to be washed periodically, you should choose paints for walls and ceilings with an abrasion index of at least three thousand cycles.
Water-dispersion materials are inexpensive, and any color can be obtained using color pastes.
Latex paints may differ in composition, which determines the possibility of using paintwork materials for interior or exterior use. Ingredients that can be used for exterior finish, introduce additives that prevent the formation of fungus and mold. They are more resistant to UV and precipitation. In addition, water-based paints are classified into several types depending on the binder:
For your information: consumers often have a question, what is the difference between acrylic paint and latex. This is tantamount to comparing apple juice with an apple useful substances more in an apple, but the juice lasts longer. acrylic paint- is a variety latex formulations, in which, in addition to natural rubber particles, synthetic acrylate copolymers are included. That is, acrylic coatings are left on the painted surface for more durable layer, but they contain synthetic acrylic particles.
Name | Compound | Peculiarities |
Water dispersion | Butadiene-styrene dispersion composition | The strength of the coating is higher than that of polyvinyl acetate compounds, but lower than that of acrylic, affordability |
Acrylic by latex technology | Dispersion based on polyacrylates with the addition of latex of various origins | Durable coating plus cost reduction due to the addition of styrene-butadiene component |
Acrylic by latex-free technology | High-quality polyacrylate base without dispersion latex component | Manufactured exclusively in the USA, highly resistant and high price |
Acrylic with latex | Contains acrylic copolymers combined with styrene butadiene | No different from acrylic paint using latex technology |
water emulsion | The composition of water and particles of the coloring matter - latex | The same composition as the water-dispersion latex |
Conclusion: if the manufacturer indicates “Acrylic paint with the addition of latex” on the can, this is a durable composition according to affordable price with optimum consumption. The difference between water-based and water-dispersion latex paint for ceilings and walls from acrylic is a shorter service life and lower resistance to various negative factors.
On the video: water-dispersion paint and its features.
Latex paint creates some effect on the treated base - a matte or glossy surface, a semi-matt or semi-gloss effect, a perfect gloss or a perfect mat. It is necessary to take into account the gloss parameters, especially for interior work. From too shiny walls and ceilings visual perception the room becomes tiresome. Glossy latex paint has the following advantages:
Matte paint, unlike glossy paint, has opposite properties- visually reduces space, is less washed from dirt, well hides defects in the base surface, wears out less during washing and care. Semi-matte, semi-gloss and matte paint- most suitable option for decorating walls and ceilings. The main advantage of all latex compounds is high permeability. Walls, ceilings and other painted surfaces "breathe" well under a layer of paintwork.
The use of interior latex paint is environmentally friendly safe way furnish the premises. The compositions do not contain toxic substances, dry quickly and do not leave a characteristic smell in the rooms.
Dilute water-dispersion paints it is possible only with water - not technical, but drinking or purified. She has optimal indicator rigidity.
There is no fundamental difference when painting walls and painting the ceiling with latex paint. The only condition is that it is possible to process ceilings only in rooms heated in cold weather, otherwise the coating will quickly crack. Can be used in damp rooms. The execution of the work consists of the following steps:
Matte and gloss paint for walls and ceilings must be completely dry before applying the next coat. The average polymerization time of the composition is 6 hours.
It is convenient to use a roller for work: it does not leave marks on the surface, saves the consumption of the working composition. Hard-to-reach areas of walls and ceilings are treated with a brush.
AT contemporary art interior design, a new trend has appeared - interior latex paints. This is a water-dispersion or water-based latex paint with a silicone resin base. They have impeccable quality, rich shades, abrasion resistance and a high price. The properties of interior paints are demonstrated by the composition "Expert" - water-based paint for ceiling and walls:
Interior paint "Expert", according to experts, fits well on the old coating after treatment with a high-quality primer. But since the material is expensive, it means that it is still worth preparing the surface according to all the rules. Latex interior paints can be used to treat plaster, gypsum, cement, and the coating hides cracks in the base base up to 2 mm deep. How to dilute latex paint for interior decoration? Only water.
Latex paint for ceiling and floor different formulations. If the manufacturer does not indicate that the water emulsion is suitable for painting the floor, this cannot be ignored. Latex-based dispersion paint for walls and ceilings not suitable for processing floor covering or, for example, facades.
Coloring latex compounds show high efficiency in interior and exterior work. They dry quickly, stand acceptable, create a reliable layer on surfaces. The compositions are safe and can be used for a variety of finishing works.
Undertaking repairs in own house, the owners try to think through every detail upcoming work and select appropriate materials for it. For decoration internal surfaces wallpaper, tile, stone can be used, but most often in recent times used wall paint. Latex products, thanks to a number of positive qualities, stands out noticeably against the background of other coloring compositions, gaining more and more sympathy from the consumer. For this reason, in today's article we will pay attention to latex paints, we will analyze their types, properties and application technology.
Latex compounds are called with the addition of polymer components that give them special qualities. Successful combination latex and acrylic allowed to improve the performance characteristics of coloring compositions and significantly expand the scope of their application. Coatings on this basis are made for both external and internal work. Information on their use is usually indicated on the packaging.
Wall paint (latex) is produced exclusively in white, so in order to achieve the desired shade, it is necessary to add tinting pigments to it. The resulting composition can be used to paint absolutely all types of surfaces: brick, concrete, covered with wallpaper or plaster.
Latex products have gained their popularity due to a number of positive features. Namely:
No harsh odors
Environmental friendliness;
The ability to pass air through itself;
Excellent thermal insulation characteristics;
Resistance to temperature extremes;
fire safety;
Possibility of dilution with water;
Drying speed;
Resistance to moisture;
Durability and resistance to abrasion.
However, in addition to positive characteristics, several disadvantages that this wall paint has should be mentioned. Latex dispersion cannot be tinted into rich and bright colors, and is also an excellent environment for the development of bacteria and fungi. In order to prevent the appearance of mold, it is necessary to treat the surface with a primer before applying the coating.
Latex-based coloring compositions can be called universal. They adhere perfectly to both previously painted and clean surfaces. The scope of their application depends on the composition and functional purpose of the dispersion. Yes, for external works Acrylic silicone coatings containing an antifungal agent are used. This type is characterized by increased wear resistance, does not fade under the influence of sunlight and is not afraid of moisture.
Latex paint for interior work has 3 varieties: polyvinyl acetate, butadiene-styrene and acrylic compounds. Next, we consider the features and purpose of each type in more detail.
People are used to calling them. The basis of this substance is ordinary PVA glue. Water-dispersion coatings contain no solvents, so they are practically odorless. Aqueous dispersions are characterized by excellent adhesion to the surface and ease of handling. Until the moment of complete solidification, the paint is easily washed off from hands and working tools. The positive features include low cost water products, however, it can not be used everywhere.
Practice shows that even after complete drying, the paint has a chalky effect. If clothes are leaned against a painted surface, it will become white color. It should also be noted that this coating is prone to washing off, so it is strongly not recommended to paint the facade or walls in the bathroom with it.
Most often, this type is used for finishing ceilings in heated rooms.
Styrene-butadiene compounds are all produced on the same water basis, but unlike the previous type, they have increased moisture and wear resistance. This allows them to be used on almost all indoor surfaces. The main disadvantage of latex emulsions of this type is that under the influence of ultraviolet rays, they lose their brightness and color saturation. Nevertheless, this property does not prevent their use in interior decoration. Such paint is optimally suited for the kitchen, hallway, pantry, dressing room and other darkened rooms.
Acrylic latex paint for interiors is considered the highest quality product of all the above options. It is used in cases where it is necessary to create a strong, durable and stain-resistant coating. Surfaces painted with such compositions become less vapor-permeable and more protected from corrosion. Typically, acrylic paint is applied in two layers, while the resulting coating is characterized by elasticity and the ability to hide small cracks in the wall. With this coating, you can safely finish the walls in the bathroom and kitchen, since it can withstand about 5000 wash cycles.
When choosing a coloring agent, it is necessary to pay attention not only to color, but also to such important parameters as: wear resistance, gloss, moisture resistance and hiding power. Any latex composition has one of six possible degrees of gloss, which is indicated on the can:
An indicator of 11-25, or "PM" means that the paint is semi-matte;
The value 30-59, or "PG" - indicates a semi-gloss composition;
Marking 6-10, or "M" - indicates that the composition is completely matte;
Indicator 60-89, or "G" - glossy;
90-100, or "SG" - indicates the absolute glossiness of the substance;
0-5, or "CM" - indicates that this is a completely matte latex paint.
Composition with maximum level gloss allows you to create almost mirror surfaces so it should be used with extreme caution. Matte finish is considered more versatile.
Wear resistance and resistance to moisture are equally important factors. If you are interested in kitchen paint, then you need to choose products with the maximum wear cycles (more than 3000).
Thixotropy indicates how quickly the paint will dry after application, while hiding power indicates estimated consumption means for covering flat surfaces.
When purchasing coloring compositions, do not forget to buy a paint roller. For latex products, you should choose painting tool with a big pile.
Latex paint application technology includes preliminary training surfaces.
It is performed in the following order:
First of all, the walls must be cleaned of dust. This can be done by wetting them twice with water.
A spatula removes old plaster, whitewash or other coatings.
If desired, you can treat the walls with reinforcing acrylic impregnation which will prevent cracking of the base.
If there are defects on the surface, they are eliminated with putty and a wide spatula.
Uneven areas are smoothed and re-primed.
1. Before starting work, wall paint (latex) is diluted with cold water.
2. To apply the first layer, use 1 liter of water for every 5-10 square meters walls. For all subsequent staining, you need to take much less liquid. You can determine the exact amount by studying the manufacturer's recommendations indicated on the package.
3. You can use a roller or a spray gun to finish the walls.
4. When painting in several layers, each new layer should be perpendicular to the previous one. The final staining should be carried out strictly in the direction from the window.
5. The roller is rolled out on a special paint tray or on a piece of thick cardboard.
In general, the technology for applying latex dispersions is not much different from the process of staining with other compositions. However, to create a beautiful, silky and durable coating, completely preserving the original structure of the base, only latex paint can. The price of the product attracts a large number of customers, making it more and more popular. So, the cost of waterproof compositions varies from 1500 to 2000 rubles per 5 liters. Variants designed for dry rooms are much cheaper. In this case, the resulting coating will last long years without requiring repair.
May 15, 2018Greetings, my dear readers!
It is no secret that there is such a problem as the choice of paint for finishing the facade of a building. After all, some types of coatings are excluded immediately, they are suitable only for interior work.
Now manufacturers produce a lot of types of coatings suitable for outdoor use. Among them and acrylate paints. They will be discussed in this article.
The characteristics of the paint used under very adverse conditions must be special. First of all, it must endure all types of atmospheric and mechanical influences.
At coloring composition for external work there must be a set of certain qualities. First of all, it is:
A photo | Description |
Resistance to extreme temperatures
The paint should tolerate negative temperatures well in the cold season (November-March) and heat in the summer. |
|
UV resistance
The coating should not crack and fade from direct sunlight. |
|
Resistant to sudden temperature changes.
They are characteristic of the off-season and can reach 20 ° C during the day. |
|
Resistant to all weather conditions
This is high humidity and dry air, precipitation, etc. |
|
Resistance to chemically aggressive substances |
Paint for exterior woodwork should have additional properties:
Acrylic paint has all of the qualities listed above. In addition, she:
Acrylic and methacrylic are the binders used in paints called acrylics. These polymers are derived substances from the essential elements.
100% acrylic film-forming agent is optimal for façade coatings:
But the paint on pure acrylic, with all its advantages, has one significant drawback - it is very expensive. Therefore, manufacturers often use binders consisting of a mixture of acrylic and other, cheaper polymers. Such compositions are called acrylate-copolymer or simply acrylate.
Most often as an additional binder apply:
Using these copolymers, it is possible to improve the characteristics of coatings. At the same time, the cost of paint drops by almost 2 times.
Water-based acrylate dyes can be applied to almost all types of facades:
Rules for the use of material:
Containers with acrylate paint must be stored at a temperature of at least +5 °C. The room must be dry. Buckets should not be exposed to direct sunlight. Guarantee period material storage is 12 months.
Here are the brands of acrylate paints that can be recommended for work:

Repair-a kind of condition. It borders on an indescribable feeling of novelty and change, but at the same time, the solution of problems regarding the choice of optimal building and finishing materials does not stop. Wide range of construction products can lead to a state of confusion and confusion. Modern directions in interior decoration are presented in the form of unusual colors and textures, which are achieved through the use of various types colors. The most popular are acrylic and latex.
Acrylic paint is a substance that is used in painting various surfaces, consists of acrylic resin. The drying process is accompanied by active evaporation of solvents, and the remaining mastic forms a reliable and durable surface.
This material is universal, it can be used on any surface, drying time is 5-30 hours. The end result suggests a matte finish. Acrylic paint is practically odorless, and the brushes are easily washed off with ordinary warm water after use.
Compound alkyd paint presented in the form:
Paints of this type are distinguished by a rather high price and durability of the coating. This type of paintwork material has a huge scope. Acrylic paints are used in:
Thus, Acrylic is a universal product for painting almost any surface..
Latex paint contains synthetic rubber in its composition, which is referred to on the labels of manufacturers as styrene-butadiene. It makes it possible to obtain a qualitatively painted surface resistant to external factors.
The presence of rubber increases the quality indicators of coatings, especially since many manufacturers supplement the composition with copolymers to attract certain features. Latex paints have a number of properties:
Latex paints can be various varieties: matte, glossy, for outdoor and indoor use.
The common parameter that unites these two products is that they belong to LCM. Also match physical properties colors, their water base. They are distinguished primarily by the main active ingredient: in acrylic, a copolymer, in latex, synthetic rubber. Latex dyes inferior in strength to the painted surface of acrylic counterparts. The pricing policy also differs significantly in favor of more budget option with rubber backing.
But, there is a completely new trend among manufacturers of the chemical and paint industries. Many companies offer consumers some hybrid of latex and acrylic paint. As part of such coloring material both main components of the two colors are present.
Thus, the presence of a variety of finishing materials makes it possible to choose the most suitable option in terms of quality, properties and pricing policy. Democracy and liberalism in choice are the main parameters that drive the building and finishing materials market.
Before proceeding with the repair, users have many questions. Many people cannot decide which paint to use. The most popular are latex and acrylic formulations. On the construction market they are often confused, so it can be difficult for a simple buyer to make a choice in favor of a particular product.
The latex mixture consists of concentrated pigment, various dispersions, preservatives, solvent and water. Often, substances are added to the composition of such materials that make the characteristics of the resulting coating much better. As for acrylic paint, as a rule, there are no impurities in it, but there are concentrated elements.
There are many different colors. However, the most common are latex and acrylic options.
Acrylic options were not always popular, as they were expensive. However, today they are in demand. In their performance characteristics and significant parameters, these paints bypassed other compositions. They are very beneficial to use. In addition, they are used both for outdoor and for interior decoration. Moreover, they are very economical.
There are also special acrylate paints. Hearing this name, many consumers are wondering what is the difference between acrylic and acrylate mixture. There are no big differences between them. Acrylic paint is the same composition as acrylate paint. It's all about marketing strategies- it is better to sell the material under different names, creating the illusion of diversity.
Latex paint is used for interior and exterior finish. To prevent the appearance of mold, a certain substance is included in it. There are several varieties of popular latex paints. For example, to create a beautiful relief on the bases, textural compositions are used.
Let's take a closer look at the popular varieties of acrylic and latex paints.
Polyvinyl acetate paint is one of the varieties of latex compositions. AT Everyday life it is referred to as "water emulsion" or water dispersion paint. It is based on PVA.
There are no solvents in the composition of such products, but it has a slight odor. However, this type is different good qualities adhesion. In addition, when it is still fresh, it can be washed from tools and skin. An equally important advantage is the relatively low price.
The disadvantage of this paint is its washability even after complete drying. It is not recommended to use when painting facades. Moreover, it has a chalky effect on its surface, so you can’t lean against it - clothes can get very dirty.
"Water emulsion" is often needed when painting hard-to-reach places in dry rooms. The disadvantage of such a coating is the lack of frost resistance, so it is not suitable for painting rooms that are not heated in winter. country house She better not paint.
Butadiene styrene varieties of paints are otherwise called water-based and latex. These compounds are resistant to wear and moisture. Washing off such coatings from the base is not so easy. However, styrene-butadiene mixtures have their drawbacks - they do not like contact with light. When exposed ultraviolet rays such paint loses its original appearance.
Such material is applicable for interior decoration, because the sun's rays do not reach all surfaces inside the rooms.
Acrylosilicate varieties of paints have light and moisture resistance. In addition, they are characterized by high vapor permeability, which is especially important when painting facades.
Often, acrylosilicate mixtures are purchased instead of silicate and silicone options. Similar materials finishes are similar in many respects to silicate paints, however, are inferior to them in price.
Acrylic and latex blends are similar in many ways. However, the acrylic composition differs from the mixed latex options in its content.
They are synthetic resins. It is worth considering one more fact - natural latex derived from the rubber tree is not added to these paints.
Very often such paint coatings do not distinguish because they are similar in operational and physical characteristics. These Decoration Materials form a protective elastic film when dried. But acrylic bypassed latex in terms of the strength characteristics of the final coating, because it is more moisture and wear resistant.
To choose a paint, you must select suitable color and understand all the characteristics that it possesses. Special attention should be given to the degree of gloss - there are several.
You should also pay attention to such characteristics as thixotropy and hiding power. The first is responsible for the occurrence of smudges. Thixotropy affects how quickly the paint thickens.
With a long thickening, stains are revealed. Hiding power indicates the formation of a film without baldness - the consumption for a normal coating.
Latex and acrylic compounds are used to finish many surfaces, such as concrete and wood. The ability to apply them in cold climates has made these paints more popular and versatile. However, it is worth noting that it is recommended to work with acrylic options at a temperature of at least 10 degrees.
From all of the above, we can conclude that acrylic and latex coatings are about the same thing. High-quality solutions are used for both interior and exterior decoration. Moreover, modern acrylic compositions are used for creativity - they are often used in painting. Also, these paints are automotive.
