What is the difference between alkyd paint and acrylic paint: choice of coating. Acrylic paints PEBEO, Studio Acrylic set

Many novice artists wonder which paint is best to choose for their work. People who decide to renovate their home face the same problem. Often the choice is between oil and acrylic paint. It can be difficult for a person who has not encountered them before to make a decision, because he does not know all the intricacies of working with these paints and varnishes. This article will tell you about the main characteristics, advantages and disadvantages of these types, as well as their differences.

Features of oil products

Oil paints are made on the basis of natural drying oil or its synthetic analogue. A coloring pigment is added to the base and ground in drying oil until a homogeneous base is obtained.

Literally 20-30 years ago, this group of paints and varnishes occupied a leading position in the market. Oil paints were used to paint literally everything both outside and inside buildings. However, gradually they began to fade into the background. First they were replaced by nitro enamels, and then by water-dispersed paints.

An artist can work with oil much longer than with any other material, because it remains moist quite for a long time.

Before starting work, you must carefully prime the canvas. After the drawing dries, the paint will not change its color or fade.

The multi-layer nature of oil painting allows you to convey a special depth of image. Only this view art materials helps the artist apply complex combinations, creating the illusion of reality.

Canvas primer

The advantages of this group of paints are obvious.

• Low price category. This factor is very important for many buyers, especially when it comes to processing large areas.
• The product is moisture resistant. It does a good job of protecting wood, concrete and metal from water. This property allows the paint to be successfully used both outside and inside.
• Ease of use. Many people doubt whether it is possible to apply a layer of acrylic coating over an old oil layer and therefore opt for what is already available. This means that many problems with preparing the surface for painting will be avoided.
• There are no additional instructions for working with the product. You just need to add the solvent and mix the composition well.
• The consumption of this group of paints and varnishes is significantly less than that of other products, since it has a high degree of filling.

Have oil paints and a number of shortcomings.

• This type of material is very toxic. It is not advisable to stay in the room until the painted surface has dried.
• This group of paints is not characterized by high coating strength. Layers need to be updated regularly, which requires additional time and expense. Over time, the coating begins to peel off, which also leads to damage to the materials on which the paint was applied.
• The color palette is limited.
• The applied paint takes a very long time to dry (1-2 days).

Features of acrylic compositions

The main components of this group are acrylic composite and water. During the drying process, not only moisture evaporates, but also polymerization of the components occurs, resulting in the formation of a highly durable coating.

Acrylic is suitable for working with glass, metal, wood, canvas, linen and other materials that have a non-greasy base. Fresh stains of this type of paint can be easily washed off with plain water. However, if the stain has already dried, you have to resort to using a solvent.

When working with this group of paints and varnishes, you should remember that the surface to be painted must first be thoroughly cleaned of dirt and dust, and also degreased. You cannot work with these paints at temperatures below 10°.

Advantages of acrylic paints.

• The products are non-toxic and considered environmentally friendly. They are practically odorless and do not contain harmful substances in the composition.
• Wide color palette allows you to choose an option for every taste. In addition, you can prepare the shade you need in a special machine.
• Acrylic paints are resistant to ultraviolet radiation, high humidity and temperature changes. They can be used for finishing both indoors and outdoors. Also, this group of paints and varnishes has a vapor-permeable coating layer, which eliminates the accumulation of moisture in the walls.
• Acrylic coating is durable (it remains in excellent condition twice as long as oil coating).

Wide color palette

The paints are non-toxic and safe for humans

• The layers dry very quickly. There are brands whose compositions dry in 1 hour.
• The quality and aesthetics of the appearance of the painted surface will satisfy the most demanding customers. After drying, the layers do not crack.
• The paints are frost-resistant (freeze at temperatures below – 40°). However, it should be remembered that thawing should be gradual, even if it takes several days. This process cannot be accelerated by using heating devices, hot water etc. After the paint has thawed, it is necessary to check whether thickened particles have appeared in it or whether it has peeled off. Then you should thoroughly stir the composition and dilute it with water, if necessary.

Layers dry very quickly

After drying, the layers do not crack

Quality and aesthetics of appearance

The disadvantages of this group of paints and varnishes include their high cost. Also, acrylic paints will not allow the artist to work “raw”. They cannot convey the full depth of the work, but skillful handling of them allows you to work on a quickly drying layer.

Comparison of two groups of paints and varnishes

The similarities and differences are as follows:

• Acrylic materials are more expensive than oil ones, but they do not have to be renewed every year, wasting additional money and time.
• Both groups allow you to perform work both indoors and outdoors. They are resistant to high humidity and protect the material they cover well.
• Unlike acrylic paints, oil paints are very toxic.
• Oil paints take much longer to dry than acrylic paints.
• The color palette of acrylic is much wider (compared to oil). However, the colors of oil paints tend to be brighter and more expressive after drying.

The paints have completely different compositions. The advantage of acrylic paints is that their solvent is water. Even an allergic artist can easily create masterpieces with them. Oil-based paints and varnishes can also be used by artists with allergies, but only if they are diluted linseed oil, and this is an expensive pleasure. Most often, such paints are diluted with turpentine, white spirit and other strong-smelling solvents.

Both experienced and novice artists care about painting their masterpieces. However, if the former have long ago decided on the choice of optimal paints, then the latter may be somewhat confused. On the one hand, I would like to give preference to bright, thick gouache. However, on the other side of the scale are acrylic paints, which today enjoy wide popularity among creative people. What are the advantages and weak sides these materials? Let's try to figure out how gouache differs from acrylic paint.

Definitions

Gouache– a type of water-soluble adhesive-based paints with a dense matte texture. The product has rich history, because it was used back in medieval Europe. However, the term arose only in the 18th century in France. During the Middle Ages, gouache in combination with watercolor was used to create book miniatures. Renaissance artists used the material to make sketches and other preparatory work. The heyday of technology occurred at the end of the 19th – beginning of the 20th centuries. Domestic artists painted theatrical costumes and posters with gouache, created sketches of scenery and large easel works. By the way, the word gouache is translated from French as “ water paint" It is made from adhesive pigments mixed with white. The latter give the paint a spectacular matte velvety finish. Despite the fact that gouache is independent equipment, it is extremely rarely used by professional artists. Many artists consider it suitable only for creating children's drawings and designing posters.

Gouache

Acrylic paint– water-dispersed paint made on the basis of polyacrylates and their copolymers. It is used both in painting and in construction when carrying out outdoor and interior work. Speaking a worthy alternative oil paints. It can be applied to paper or planes in liquid (with the addition of water) or paste form. The last option is the most popular among professional artists. Acrylic does not crack, lays down as an even film, is slightly shiny and does not require fixing. Sometimes the paintings he painted resemble works done with watercolors or oil paints. However, in most cases, acrylic has a unique color rendition that is unattainable in other areas. visual arts. Largely due to this, he enjoys wide popularity among contemporary artists.

Comparison

The first difference lies in the composition of the products we are interested in. Gouache is made with the addition of white. In this regard, the paint after drying becomes significantly lighter and becomes matte. In general, the composition of gouache is similar to watercolor. Whereas water-dispersed acrylic has a structure similar to oil paints. It dries very quickly, which cannot be said about gouache. As long as the paint remains wet, it will not special labor can be washed off with water. Acrylic is highly durable, it does not fade in the sun, and does not spread when applying a new layer. With gouache everything is exactly the opposite. But it is much thicker and denser than acrylic paint. Due to the high content of coloring pigments, gouache is characterized by a very saturated color, and the pattern it creates is opaque. Acrylic paints lie on the surface much smoother, as if forming an invisible film on it. After drying they darken a little. Gouache gives a thicker and uneven layer. The transitions from one shade to another are quite abrupt.

Another significant difference between gouache and acrylic paint is the area of ​​​​use of materials. As a rule, the first is used for drawing on paper of any thickness, and less often for painting fabrics. Acrylic is characterized by a wide range of applications. It is indispensable for painting ceilings, walls and other surfaces on a wooden or metal base. Creating drawings, painting on glass, decorating ceramic products, applying images to fabric and leather, airbrushing - the list of possibilities of acrylic paints is very extensive. This explains the relatively high cost of the material. If gouache is sold exclusively in sets with a certain number of jars in a box, then acrylic paints are often sold individually. They are bottled in a wide variety of bottles, be it miniature tubes of 20 ml or large bottles with the capacity of a standard glass.

Let's summarize what is the difference between gouache and acrylic paint.

How to choose paint for wood, for example, for the facade of a building? A number of product items are eliminated immediately; they are suitable only for interior work. Here you need to understand that the properties of the paint that will be used in sufficient unfavorable conditions, must be specific: we expect increased stability and durability from such paint.

The modern chemical industry offers a lot of options, including acrylate paints from various manufacturers (Finnish, Canadian, Russian). And in many cases, the use of such paint is preferable.

Acrylate paints on wood for exterior use

Exterior paint must have a formula that is unique in many respects.

Such construction material must demonstrate stability:

• to low temperatures throughout the cold period, from November to March;
• To high temperatures throughout the summer period;
• to possible sudden changes temperature (up to 20 degrees per day);
• to the influence of direct sun rays and high humidity;
• to action chemical substances(in precipitation).

Painting wood: what is important to consider?

When painting wooden surfaces It must be taken into account that wood is a special material. It's natural organic material, which is characterized by such disadvantages as the possibility of rotting, damage by mold, and other harmful microorganisms. In addition, the material has a specific structure (depending on the type of wood), which I would like to preserve without having a destructive effect on it.

Painting is a means of protecting your wooden house, increasing its durability and improving its appearance for decades.

In this regard, we can add new items to the list of requirements for paints for exterior woodwork.

Such building material should:

• have antiseptic properties;
• provide protection from the influence of various microorganisms;
• preserve the structure of the tree, give it the opportunity to “breathe” to maintain the microclimate in the building.

Acrylate paints for exterior woodwork from the Finnish Tikkurila are some of the most popular on the market

Choosing paint: weighing the pros and cons

What offers do we have from manufacturers? The choice among excellent building materials is quite rich. Many specialty modern exterior paints meet most of the above requirements. Moreover, they are different beautiful shade, which does not disappear over several years.

Each type of paint has its own advantages, and to make the right choice you need to understand what characteristics are important in your case.

For example, traditional Oil paint not only has good performance, but also a heavy odor, and when using them there are difficulties with long drying times. Another problem: they quickly lose their brightness. Moreover, their price is acceptable for many.

Oil paint for exterior and interior use

Acrylate paints belong to the family more modern materials. They are environmentally friendly, allow the wood to breathe, and ensure air penetration through the entire surface (important for any type of wood), which makes the house more durable. In addition, they have almost no odor and do not have any harmful effects on performers construction work. Such paints dry in a short time.

A wide range of tools can be used for painting with acrylate paints. In any case, the result of construction work will be excellent: a brush, a spray gun, and a roller of any size will do. The consistency of the paint allows you to change tools without compromising the quality of the final work. The facade will look great! And one more serious argument in favor of acrylate paints: they mix well with each other (which cannot be said about oil paints). This property allows you to create new non-standard shades.

When using acrylate paints, the color layer is highly elastic. This gives the effect of a smooth, even coating on which even small cracks do not appear, despite the shrinkage processes of the building.

Characteristics of acrylate paints for exterior woodwork

The advantages of such paints include:

• resistance to all weather conditions;
• breathability;
• ease of application;
• quick drying;
• excellent adhesion;
• Can be used for any type of wood;
• optimal consumption;
• preventing the formation of rot;
• slow wear.

But the only disadvantages include:

• high price;
• the need to use a high-quality primer.

Application of acrylate paints

Acrylate and acrylic: what is the difference?

Let's look at another nuance: what is the difference between acrylic and acrylate paints. You will see both names on the shelves of building materials stores. Maybe we are talking about the same product, which different manufacturers simply call differently? No, the difference still exists and lies in the addition of specialized chemical impurities: In acrylic paint, the binder is concentrated compounds. No additives or impurities are used. For the production of acrylates, special substances are used: acrylate-copolymer dispersions, which reduce cost and also add beneficial features(for example, they increase the permeability of the paint surface to water vapor - this provides a “breathing” effect).

At the same time, the similarity between acrylic and acrylate paints is not limited to just a certain commonality of name: these building materials have a common base and a certain similarity in properties (dry quickly, do not lose shade intensity).

What is the difference between acrylic and acrylate paints?

Acrylate paints: main manufacturers

Let's look at the main manufacturers of acrylate paints. The buyer should decide in advance which companies produce building materials with a suitable price-quality ratio for you.

• "Tikkurila";
• Dufa;
• Teknos;
• "Olivesta";
• Isaval.

In the ranking the best manufacturers Tikkurila (Finland) is in first place. Finns are great at painting wooden buildings, located in harsh northern conditions - their houses have always been distinguished by bright, rich colors. In Scandinavia, acrylate paints from Tikkuril are the quality standard for painting wooden facades.

Matt acrylate Tikkurila paint Pika-Teho – Pika-Teho

Statistics say that in the Scandinavian countries over 80% of all wooden houses painted with acrylate (and acrylic) paints. The company uses only high-quality raw materials to produce products. If we talk about the shortcomings of Tikkuril, we must admit that the price of paint from this manufacturer is high.

The Canadian manufacturer Forester is also distinguished by its competent approach to the production of paint and varnish products for coating wooden houses located in the temperate zone. An excellent palette of colors, stability, unsurpassed brightness - all this can be said about Forester. The company also offers a wide range of primers and other special materials for processing wooden surfaces. The price of building materials from Forester also cannot be called affordable.

The German company Dufa produces acrylate paints High Quality. Reviews of their products are consistently positive. For example, white paint produced by the Dufa company retains its pristine whiteness for many years.

There are other, lesser-known European manufacturers who produce paints of consistently high quality; among them:

• VivaColor (Estonia);
• Reesa (Germany);
• Isaval (Spain).

Instructions for painting a wooden facade using acrylate paints

The process consists of several stages; let’s look at the features of each of them.

Stage 1. Estimation of the scope of work and materials

Buy paint from the same manufacturer: even if it’s on the packaging different manufacturers The same color is indicated, this does not guarantee a complete match of the shade. For example, traditional White paint, produced by different companies may have noticeable differences.

Step 1. First of all, you need to estimate how much paint, primer and preservative (if necessary) you will need. To do this, measure the area of ​​the facade.

Step 2. Different types of paints use differently, so here you will need to refer to the instructions printed on the packaging of the selected paint. There, the manufacturer always indicates the amount of paint that is spent on painting a particular surface. On average, modern acrylate paints are consumed in a volume of 300-400 ml per 1 square meter. m. However, these are average figures; it is better to clarify this point in the instructions.

Scope of application of facade paints and approximate service life

Step 3. By multiplying the figure indicated there by the area of ​​the facade, you will get the total volume of paint.

Step 4. Divide this figure by the volume of the can of paint you choose to get the number of cans of paint you will need for the renovation.

Step 5. Round this number up to make a margin.

You also need to check the ambient temperature suitable for painting with this type of paint. Modern paints can be used even at subzero temperatures, but it is always better to clarify this in the instructions, and ideally carry out repair work at temperatures above + 5 degrees.

Stage 2. Preparing tools

For painting wooden facade you will need:

• required amount of paint;
• required volume of primer;
• antiseptic;
• several large and medium brushes for painting the borders of surfaces;
• several large enough rollers to paint the main area.

Facade painting tools

Stage 3. Preparing the wooden surface

In order for the paint to apply evenly and better and stay on the facade for a long time, it is necessary to prepare the wooden surface. The wall must be clean, free of dirt, so remove any remaining peeling old paint and mold with a stiff brush or spatula.

Stage 4. Primer

It is better to use the same brand of primer as the paint. Calculate the surface and cost in advance, although with a primer it is somewhat easier - here you are not subject to the risk of color mismatch.

If for some reason you cannot find a primer of the exact same brand, purchase a product from another manufacturer, but suitable for exterior woodwork (plus one that matches acrylate paint). Such preparation will improve absorbency and give a smooth, beautiful surface after painting without uneven spots of a different shade.

Step 1. Clean the surface from dust.

Step 2. Fill all seams with a special wood putty.

Step 3. Apply antiseptic (if there has been a mold problem) along the wood grain.

Step 4. Apply primer (1 coat).

Applying primer to the facade of a wooden house

Step 5. Wait until the primer is completely dry before applying paint.

Stage 5. Preparing the paint

Different manufacturers require different steps when preparing paint for application to a wooden surface. Due to this general recommendations It is impossible to give, you should carefully read the instructions on the packaging. Dilution with water may be required, but the volume of water should not exceed the amount specified in the instructions.

Dilution of paint

Step 6: Painting

Carry out painting on a dry, sunny day. Do not carry out repair work in rain, extreme heat or extreme humidity.

By doing repair work with acrylate paints, you will need to apply two to five coats (to ensure the wood has good resistance to insect damage, mildew, and rich color). When painting large surfaces, it is wiser to use a roller.

Painting the facade of a wooden house with acrylate paint

The sequence of actions is given below.

Step 1. Stir the paint thoroughly.

Step 2. Dip the roller into the paint, make sure it is completely saturated with the solution, then lightly roll it over the piece of material you don’t need. This will help you get an even, high-quality coating without streaks.

Step 3. Apply the first coat of paint. It will take 3 to 4 hours for the surface to dry.

Step 4. Apply at least two to three more coats to ensure color durability and vibrancy. When painting, start at the top level, then work down to the lower areas.

In this article we will talk about choosing interior paint for walls and ceilings. interior spaces. It’s easy to buy paint, but if you want it to fit the room perfectly and make you happy for a long time, you will have to approach its choice with all responsibility.

As already mentioned, for living rooms it is better to use water-dispersion (water-based) paints, as they are the most environmentally friendly clean materials. They do not contain solvents, are practically odorless and have excellent technological parameters.

What is paint made of?

Classification of water-dispersion paints

Water-dispersion or water-based paints

What is the difference between enamels and paints?

What is paint made of?

The paint consists of the following components:

• Binders glue the components (solid particles) and form a paint film on the surface. Many basic properties of paint, such as abrasion resistance and moisture resistance, depend on binders. The binder is also responsible for the adhesion of paint to the surface.
• Pigments or dyes give the final color and affect the hiding power of the paint. They also protect the painted surface from exposure to ultraviolet radiation, and many have anti-corrosion properties.
• Fillers provide the required opacity (hiding power) of the composition.
• Supplements are designed to enhance one or another property of the paint and ensure the manufacturability of the surface painting process. Depending on the purpose of the paint and the manufacturer, various emulsifiers, stabilizers, defoamers, thickeners, waxes, corrosion inhibitors, antiseptics, substances that reduce drying time, etc. are added. Some additives and excipients improve the durability and weather resistance of the painted surface.
• Water And solvents create necessary environment for the listed components and impart the necessary viscosity to the paint and varnish composition.

Classification of water-dispersion paints

In addition to pigments and fillers, water-dispersion paints contain whole line various auxiliary additives, but we are more interested in the type or nature binder(film former), according to which all paintwork materials are classified.

The most popular are the following types water-dispersed paints:

• Acrylic;
• Silicone;
• Styrene acrylic;
• Acrylic silicone;
• Vinyl acrylic;
• Butadiene-styrene;
• Polyvinyl acetate (PVA).

In order to decide what paint to paint the walls or ceiling, we will consider the advantages and disadvantages of all types of water-dispersed paints.

Acrylic paints

Binder (the basis)- polyacrylic (acrylic) latexes (polymers).

Advantages: due to their characteristics - strength, elasticity and durability, the most expensive paints on the market water based. Acrylic paints are practically not afraid of the sun, water, and temperature fluctuations. Like other water-dispersed paints, they can be diluted with water, and after drying they become resistant to water. Suitable for both internal and external exterior finishing premises. Due to low gas permeability, they protect against corrosion reinforced concrete. Over time, acrylic paint pays for itself due to its durability and long term services. Can be used for outdoor work.

Flaws: high price, pure acrylic paint is too expensive and only well-known brands can afford to produce it.

What is the difference between acrylic paints and acrylate paints?

Essentially it's the same thing. Acrylate polymerizes to acrylic. We are purchasing acrylate paint, and applying it to the surface we obtain a coating in the form acrylic films. Thus, speaking of acrylic paint, we mean an acrylate binder.

What is the difference between acrylic paints and latex paints?

With development paint and varnish products marketers have to come up with and introduce more and more new expressions into product descriptions that emphasize the superiority of the product over competing analogues. Manufacturers often call waterborne paints polymer based latex. If natural latex is the sap of rubber plants, the synthetic latex used in paints is a dispersion of the polymers that make up the paint base. Therefore, the use of the term “latex” in the names and characteristics of paints is just a cunning marketing ploy by manufacturers to give their products additional advantages. Naturally, no one added any latex, the phrase “acrylic latex paint“It’s the same as “dairy butter” (although the example is not very good).

Thus, a manufacturer can release 5 types of the same water-dispersion paint onto the market, calling the products, for example, latex, acrylic, acrylic-latex, acrylate, water-based paints (you can also more titles come up with, the main thing is to occupy the shelves in stores). And everything will be sold successfully. And the buyer suffers from the problem of choice. Usually famous brands they will not take such a step, as they value their reputation.

Below in the text several options for acrylic and other water-dispersion paints that enjoy well-deserved trust will be presented. The list may be quite extensive, but these samples can be found on the shelves of hardware stores.

The paints discussed above are usually produced in white. To obtain the desired color or shade, paints are tinted using special tinting dyes. Tinting is carried out either manually before starting work, or at the point of purchase in special tinting machines. Well, of course, not every paint can be tinted.

Designation of water-dispersed coatings based on the type of film-forming substance

Table A.1 GOST R 52020-2003

Water-dispersion or water-based paints

And yet, as it should be, the colors water-dispersed or water-based?

And what's the difference between paint And enamel?

Dispersion is a formation of two or more elements that practically do not mix with each other and do not react with each other chemically. In this case, the first substance (dispersed phase) is finely distributed in the second (dispersion medium).

Emulsion- This dispersive a system consisting of microscopic droplets of liquid (dispersion phase) distributed in another liquid (dispersion medium).

Thus, an emulsion is one of the varieties of a coarsely dispersed system (in in this case liquid). Natural emulsions include, for example, milk, consisting of butter, casein and water.

Both dispersion and emulsion are a mixture of one small quantity substances with another. It is a mixture, not a solution, since the transition of molecules from one phase to another does not occur.

In the case of water-based paint, the first substance (synthetic polymers) is distributed in the second substance (in aquatic environment). Paint particles are suspended in water and equidistant from each other. When the paint dries, the water evaporates, and the particles come closer together and form a dense film on the surface.

Thus, we have come to the point that the phrase “water-based paint” is not entirely correct, since emulsion means a mixture of liquid elements with a liquid medium.

But no one pays attention to these nuances anymore. Just like the fact that, for example, a solution of cement with water and sand cannot be from a chemical point of view solution, but is suspension.

Suspension (lat. suspensio, literally - suspension, from lat. suspendo - suspend) - a mixture of substances, where solid distributed in the form of tiny particles in a liquid substance in a suspended (unsettled) state.

You can also refer to GOST 28196-89, which applies to water-dispersion paints, which are suspensions of pigments and fillers in aqueous dispersions of synthetic polymers with the addition of various auxiliary substances (emulsifier, stabilizer, etc.).

However, GOST 28246-2006 indicates that water-dispersion paint is a “liquid or paste-like pigmented paint material having a paint and varnish medium in the form of a dispersion of an organic film-forming substance in water and forming an opaque when applied to the surface to be painted paintwork».

What is the difference between enamels and paints?

What is the difference between enamels and paints? And what does “enamel paint” mean then?

Initially, the term “enamel” meant a thin glassy coating obtained by high-temperature treatment of oxides on the surface of metals.

This is most likely how the term “enamel paint” appeared in the descriptions for compositions that form a strong, smooth film on the surface. Moreover, GOST 28246-2006 already directly indicates that the term “enamel” means “a liquid or paste-like pigmented paint and varnish material that has a paint and varnish medium in the form of a solution of a film-forming substance in organic solvents and forms an opaque paint and varnish coating when applied to the surface to be painted.” In the previous GOST 28246-89, the terms “paint” and “enamel” meant the same thing.

Thus, enamel implies a solution of a film-forming substance, in contrast to ordinary watercolor or oil paint, which do not have such properties and remain simply “paints”.

Of course, enamel paint cannot be compared with enamel covering metal utensils for example, since these are completely different technologies.

Children love to draw. Many kids show their artistic talent from childhood. The task of parents is to contribute in every possible way to its development. To learn how to draw beautifully, you should not only attend several lessons and master classes, but also choose the ideal paints for the first time. Since the result of the work largely depends on them, and therefore whether it disappears or, on the contrary, an even greater desire to engage in drawing appears. Let's figure out what is the difference between watercolor and gouache, acrylic and oil paints, which we know, as well as what paints for body art are - face painting.

Watercolor not just the name of the paints, but also the name of the painting method of the same name. Great for little kids and beginner artists. These paints are made based on water (“aqua”). The beauty of watercolor is that the shade, whatever it is, can be changed by diluting it completely with plain water. If you wipe a sheet of paper with a damp cotton swab, watercolor paints will go to bed better. It is better to paint with watercolors on paper with a grainy structure.

Gouache differs from watercolors and other paints in its dense and opaque texture. It is better to start painting with gouache at the next stage of improving your skills. Such paints are quite saturated, suitable not only for painting on paper, and of any density, they can be used in any handmade project, painting on fabric. It is enzymes such as kaolin and white that make gouache dense and rich, which distinguishes it from watercolors and other paints. If a child makes a mistake while working with gouache, you can easily correct the drawing by applying light tone darker. Gouache becomes lighter after drying.

Oil paints are produced, as the name suggests, from oils, natural, vegetable oils. It is thanks to their composition that the color of the paints is more than saturated, and the texture is dense and viscous. Most often, only professional artists use oil paints, since thanks to their composition, the paints dry very quickly, creating unique paintings, painted, in most cases, without the help of a brush used by a beginner. It is impossible to correct a painting if you have made a mistake in technique, since the colors cannot be washed out or diluted without spoiling the overall background.

Acrylic paints, unlike oil ones, are made on the basis of acrylic and resin. Thanks to this, the colors dissolve well in water, paint residues that accidentally extend beyond the design can be easily removed, and they dry just as quickly. The main difference between acrylic paint and all others is their ability to retain color, not fade or crumble over time, either from paper or from canvas. Acrylic paints apply very smoothly, as if covering the paper with a thin film. Suitable for creating designs on glass, wood, metal and fabric. At the same time, acrylic paints can also be used for drawings in watercolor style. Acrylic paints take on darker shades after drying.

Face painting– paints designed specifically for painting on skin, even the most sensitive and childish. Face painting paints were invented by cosmetic companies and developed by them. They are hypoallergenic, do not bake, do not crumble, do not spoil the skin, at the same time they retain color perfectly and lie extremely easily on the surface of the skin. The main difference between face painting and other paints is their ability to create extraordinary masterpieces on the skin, and not on paper.

The article compares alkyd and acrylic primers, the main differences in the compositions are revealed. The compatibility of paints with each other and which one is more suitable for coating wood is described.

Comparison of formulations

The basis of acrylic paint is a polymer emulsion - acrylic mixed with pigments. The solvent is ordinary water, so the material does not have a strong odor. Acrylic is known as liquid glass, used as a binder in other construction mixtures. It also contains improving additives that affect the viscosity and temperature stability of the solution and the finished coating.

Alkyd, or oil, enamel consists of alkyd varnish, coloring pigments, and kerosene solvent (white spirit). Can be included additional additives: antiseptics, antifungal, fire-fighting additives. This enamel is often used to coat wood products. When working, careful ventilation of the premises is required: the composition has a sharp, specific odor.

Features of alkyd paint

You can find varnishes and paints.

The varnish is based on alkyd and solvents. It contains no pigments. The solution is used as a primer for other finishing coatings and as an antiseptic for wood.

The paint contains pigments. Can perform the function of surface protection. It can be glossy or matte, but this does not affect the quality of the coating in any way.

Varnish and primer have the same base good compatibility. They can be used on one surface or mixed.

Advantages

• Wide color range.
• Easy to apply, good distribution over the surface.
• The layers dry quickly.
• Resistant to cleaning.
• Suitable for interior and exterior work.
• Affordable price.

Flaws

• Strong smell.
• Low UV resistance. The coating quickly fades in the sun.
• Hardness has a negative impact on service life. Dried enamel is inelastic and does not withstand linear expansion of the surface. After a few years it cracks and requires updating.

If you need to use alkyd paint outdoors, you should choose a composition with additives. It is better to place the painted product in the shade.

Acrylic paint: features of use

Acrylic polymer is plastic. The dried coating layer is capable of stretching and shrinking with minor changes in the size of the base. The paint does not crack after frost. So that the composition adheres well to the surface wooden product, necessary:

1. Remove the old coating from the base and sand the surface.
2. Prime the material special compounds to prevent rotting and pest proliferation.

The acrylic base must be dried and free of dust. The coloring composition is diluted with ordinary water and applied to walls, ceilings, and products with a brush or roller. The paint spreads well over the prepared base.

Advantages

• Does not change color in the sun or at high temperatures.
• Thanks to its elasticity, the coating does not peel off or crack.
• Long service life - at least 8 years for wood, about 20 for metal and plaster;
• The composition protects surfaces from moisture and corrosion.
• No pungent odor. The paint does not emit harmful substances, and it is safe to work with it even without protective equipment.

Flaws

• High price.
• A long period of gaining operational strength - about a month.
• Good, high-quality composition difficult to find.

Main differences

The properties of the materials are presented in the table.

Compatibility of coloring agents

There is no need to combine formulations. Alkyd is a good primer for wooden surfaces. It is also suitable as a finishing varnish if applied in several layers.

Acrylic paint is elastic, it is optimal to use it on products subject to linear expansion due to temperature changes and humidity changes.

Is it possible to combine enamels?

To work on the same surface, you need to use products on the same basis.

Soft compounds can be applied to hard surfaces, but not vice versa.

Alkyd enamel is hard, works as a primer under a varnish layer or more soft covering . Acrylic is an elastic covering material. Can be applied to oily, dry or old base. But in this case, the service life of the finishing layer is reduced by 2 times.

The combination is suitable for wood. On surfaces made of other materials there is no point in mixing layers.

What not to do

Should not be applied alkyd enamel on acrylic surface. If this is still necessary, you need to remove as much of the old coating as possible, sand it thoroughly, then prime it.

Do not mix dissimilar components. Acrylic-alkyd enamel can only be produced industrially using special technologies. It is not used in construction.

Conclusion

The article compares two materials. It's impossible to say which one is better. When choosing, you need to take into account the expected service life of the coating, operating conditions, quality of the finished surface, and budget for repairs.
