Colors. About colors for water-based paint

In spite of huge selection various shades paints that manufacturers currently offer, a picky consumer does not always manage to find what they need. In this case, you can create the desired shade for yourself and enjoy the chosen color.

Let's first understand the concept of tinting and coloring. The concept of "color" in various fields has several meanings. The so-called "folk" meaning of this term means specific color or shade, and color experts call the composition, which is already ready for use.

Tinting is a process when paint is mixed or diluted, the purpose of this process is to achieve the desired shade of color.

Tinting can be done with your own hands or, there is a doubt about own forces, you can order a ready-made tinting in a company that specializes in this.

In what cases is it necessary to perform tinting? It is performed if:

It is necessary to select a shade in accordance with the design of the apartment.
A small piece of the painted surface has become unusable, and there is no point in repainting the entire surface.
During the repair, you made a mistake with the calculations of the required amount of paint, and now you cannot find the shade you need on sale.
Choose shades that will harmonize.

Thanks to the tinting, a small redecorating will become a successful replacement for the front of intricate painting work.

Currently, there are several types of tinting.

Computer tinted paint

First, consider computer tinting. This is our current version. What is it? You choose the shade that you need, and with the help of a specially created program, you can easily calculate the amount of paint and dye that you will need. With the computer method, you are not limited in the amount of paint. This method is unique.

It has the following advantages:

the tinting will be accurate and fast;
you can tint any kind of paint.

Manual tinting

There is also traditional hand tinting. Of course, this method will not give you as clear results as a computer one. For manual tinting, you purchase white paint and tinting paste. The more you add tinting paste, the more intense the resulting shade will be.

The manual method has its advantages:

tinting can be done independently;
it is convenient and economically beneficial.

But, using manual tinting, you will not achieve dark colors. rich colors. And also, if you need additional paint of a similar shade, then you are unlikely to be able to repeat your result exactly.

Pay attention to the lighting in your apartment - it will certainly affect the shade you choose. So, if the lighting is artificial, then any shade that you choose will have a yellowish tint. Daylight will give a more realistic picture. All items of your interior will be reflected in tinted color.

Cold colors in artificial light will appear darker by one tone. It's green and blue. And orange and yellow, on the contrary, will seem lighter to you. If your interior contains some bright objects (furniture, textiles), then the selected monotonous colors will fade against their background and be lost.

Also keep in mind that paint applied to a small segment and to a large area will seem different in shade to you. Especially if you apply it vertically. Based on all this, before you settle on any shade, consider all the features of your room.

There is in the "painting" world and such a thing as tinting systems. This is the use of base paint and color. Colors are deep or opposite colors. The pigments that make up their composition are organic or inorganic. Organic pigments tend to be used for richer shades.

But such pigments have the following disadvantages:

not every surface can be coated with such a composition;
paint with such pigments is short-lived, under the sun's rays it will burn out over time.

Colors with inorganic pigments have a limited color range, but they are not afraid of the influence of atmospheric phenomena.

The production of colorants is carried out in different versions:

pasta,
paints,
dry mixes.

The composition of the paste includes dispersing resins, such a type of pastes is also possible, where the substance used for bonding is absent.

Pastes are different types- there are generalists that are suitable for any paint, and there are specialized pastes designed for specific paint materials. Pastes are easy to use, when mixed, you can easily regulate the desired shade. But they have drawbacks: pastes do not have the shaped properties of color and saturation. The final shade may be unexpected for you.

The composition of the coloring paint does not differ from the paintwork materials for which they are used:

water emulsion,
acrylic,
oil
others.

By combining white paint and pigments, you will get the color that you need. If you need a very bright and saturated color, then the existing colorant can not be diluted.

The advantage of dry composition lies in their low price. But the color range of such pigments is very narrow, and the correction of the desired shade is very difficult, since such pigments should not be added to a ready-to-use coloring mixture.

What you will need for this process is a container of the mixture, a drill with a nozzle, a small container to hold a test portion, white base paint, color.

Coloring steps:

Sample preparation. Before making a large volume of the mix, run a small sample batch. Otherwise, you can just spoil all your material. Pour some paint (100 ml) and a few drops of the coloring mixture into our small tank. When you get the shade you need, remember how many drops you added.
Carrying out experimental tests on the working surface. As we have already mentioned, the color on the surface may be different from the color of your mixture. Therefore, we take our trial dose and try it on a small area of \u200b\u200bthe working surface. Waiting for it to dry and see what happens. Keep in mind that different lighting gives different shades.
Production of the main volume of the material. If what came out in the trial version and on the working surface completely satisfied you, then you can proceed to the main volume. How to calculate right amount color? Subtract 20% from the trial doses received. That is, if you added 7 drops of one color and 2 of the second to the sampler, then per liter of paint you will need not 70 and 20 drops, but 56 and 16 drops. When the mixture is evenly stirred, test again on the surface. Don't forget about different lighting.

The main thing - do not rush when tinting. Take your time to achieve the desired result. Otherwise, you risk spoiling all your existing materials, or achieving a color that does not suit you. Please note that it is better to prepare more paint than you need.

In case you don’t have enough paint, choosing exactly the right shade is a very difficult task. And, most likely, the shades in different containers will differ. The remaining amount will be useful to you in the future, when the time comes for corrective repairs. Pour the excess into a jar and close tightly with a lid.

You need to tint large paint in one container, otherwise, if you need to repeat the shade, you will have difficulty calculating the required volume. When you are faced with the choice of color, it is better to choose the one contained in bottles with a narrow neck - it is more convenient to calculate the number of drops. If you choose another one, you can use a syringe for these purposes.

In order to choose the desired color and the amount of color needed, you can use a special table for mixing colors.

In order for the resulting material to be evenly mixed, nozzles of various sizes can be attached to the drill.

It is better to choose paint and color from the same company, this guarantees the achievement of maximum results when mixed. As a rule, information about required volume base paint.

When painting an apartment, study the range of colors in advance. It is known that some colors have a calming effect on a person, while others, on the contrary, cause irritation and aggression.

As for the complex color, those colors that include several shades are called such. The main thing here is not to get confused in the definition of colors.

What are the colors for paint?

Colours, as a rule, are produced in the form of a consistency, which is called a paste. Such a paste is aimed at obtaining softer and more natural, natural colors. There are also a number of rules for diluting paint with color, which are written in the instructions for each product.

You can not add in any quantity, because it has a high saturation. If you add too much, you can spoil the paint. That is why you need to follow the strict instructions that manufacturers create.

Color properties are achieved by adding organic and inorganic pigments to it. Most often, organic ones are added, as they provide rich color to the color scheme. But, at the same time, the color for paint, enriched with organic pigments, has a low light fastness.

How to choose the right color?

First of all, you do not need to look towards foreign countries, since the colors of our domestic manufacturers no worse, and, in some cases, even better. In addition, domestic colors will save you money.

To begin with, you should pay attention to the container or vial that contains the material. The container should have a narrow neck so that, during the tinting of the paint, you can easily count the number of drops you need.

Also, when buying a color for yourself, do not forget to ask the seller for a color card with which you can provide yourself with the desired color.

If done 3 or more hours before painting, the color will not be as saturated, as the color will settle in the paint and lose some of its saturation.

Basic foundation

Tinting is done on the basis of the base paint. It can be white, colored or transparent. The paint is mixed with a pigment substance, it is he who gives required shade.

The most commonly used base for tinting is white. Not even just white, but snow-white, without the slightest impurity. But not every white paint can make a good base.

Manufacturers began to produce special white paint of several types at once with different content connecting element.

Paint tinting technology

The technology of tinting is the addition of color drop by drop, so it is most convenient to carry out this process using a tint with a narrow neck. If the preliminary result turned out to be lighter, you can always add more, but it is very difficult to lighten the dark one. You also need to remember that the paint in the colors tends to thicken, and the colors must be shaken before use.

It is somewhat more difficult to get the same shade of paint poured into different buckets. In order for the shade not to differ, the color must be dosed using disposable syringe, in small portions, add the same amount of color to the same buckets of paint, mixing thoroughly until the desired shade is obtained. The paint must be stirred with horizontal rotational movements.

Important Rules:

It is necessary to try the resulting shades not just on the walls of the room, you must definitely look at them both in daylight and in electric light. Electric light should be final after the chandelier has been hung. This is the main secret of how to achieve the desired tone. Tinted paint is first applied to a fragment of the wall, allowed to dry and see what the color will be in both daylight and electric lighting.
On a large vertical area, the selected tone will look richer than on a small sample. This must be remembered when mixing paints and adjust the tone recipe, taking into account this feature.
Painting surfaces treated with primers, sealants or mounting foam may give unintended results. It is necessary to carry out a trial painting.

Work process

If the color on the wall matches, tint the paint in a larger proportion from the following calculation: if 2 drops of one tone and 5 of another were added to 100 ml of white paint, therefore, 20 drops of one tone and 50 drops of another are needed for 1000 ml of white base paint .
If the color on the wall turned out to be darker, it is necessary to dilute the tinted paint according to the following scheme: if it is a little brighter than necessary, then 20% must be subtracted from the number of drops. The result will be: for 1000 ml of white paint - 16 drops of one tone and 40 of another.

The mood of the residents depends on the type of living space. Painting has become one of the most popular options for decorating interior and exterior walls. The choice of paint colors expands the possibilities design solutions, creating an individual interior. What to do if there is no product of the required shade on the market? Then color is used - with it it is easy to get the paint of the required color, saturation.

What is paint color

The word "color" is translated from the Latin "color" as a color or tone. AT chemical industry color is a special highly concentrated pigment composition, with which you can get almost any shade of paint. Moreover, not only water-based, but also facade, oil, acrylic products can act as a basis. Depending on the concentration of such a pigment composition in the paint, it is possible to achieve both saturated and bright colors, and muted, pastel shades.

The use of color helps property owners to translate into reality almost any design ideas. The process of mixing and diluting paint and varnish material with pigment is called tinting. Its use is suitable not only for finishing works inside the object, but also outside it. With the help of a special pigment solution, you can get unique shades, for example, copper, mother-of-pearl, bronze, golden tint can be given to the paint.

Kohler can be used on concrete, brick, plastered walls. Compositions with its use can also be processed and other surfaces: drywall, wood, fiberboard, chipboard. The use of tinting is necessary in the following cases:

the original layer has small defects;
you need to choose a shade according to color solution interior;
you want to decorate the interior using several shades of one or more colors;
you need to correct the errors that occurred when calculating the volume of paint or the absence of the color used earlier.

Kinds

When planning to buy a color for water-based paint, acrylic or any other, check out the types of these products. You can order it in a specialized online store with delivery by mail. According to the range of application, it can be universal, i.e. combined with any paint and varnish materials, and highly specialized. Colorants are produced in the form of paint, dry composition, paste. The latter option is more convenient to use, but there is a possibility that the intensity of the finished paint will be uneven. According to the composition, color is distinguished:

With organic pigments. Products of this type are distinguished by a more saturated range of colors, but the paints and varnishes obtained on its basis lose their brightness and saturation over time due to exposure to sunlight. For this reason, compositions with pigments of organic origin are not considered the best choice for facade paints.
With inorganic pigments. Such products are more resistant to aggressive influences. external factors including burnout. True, such a color scheme for paint cannot boast of a wide range of shades.

You can tint the paint manually or by computer. Thanks to the first option, you can save a significant amount of money and perform the procedure directly at the repair site. There is also a drawback: it is almost impossible to repeat exactly the same tone. The second type of tinting is controlled by special program. The operator only needs to select the color of the color scheme, and the program will determine the proportions itself, after which it will issue the finished composition.

Deciding to breed the pigment yourself, consider the technique:

Decide on the amount of color you need. It is better to buy more initially than to look for identical products later.
It is recommended to choose a color scheme for painting surfaces with the manufacture of a probe. To do this, fill a small container with 100 mg of white paint and add a few drops of a pigment substance to it. By mixing, get the desired shade.
Check how the resulting composition looks on the wall or other surface that needs to be painted. Not always color ready solution matches the shade of the paintwork material applied to the wall. Consider the result under the prevailing lighting in the room (artificial or natural), after the composition has dried.
If you know how many drops you had to add to get desired color, then recalculating the consumption of the composition per liter of paint, you can dilute and get required amount color.
Add the pigment composition to the paintwork material in a thin stream. At the same time, do not forget to mix everything thoroughly to get a concentrated composition with a uniform color.

How to choose a paint color

To begin with, depending on the goals, choose between organic and non-organic products, taking into account the features of each option. Then decide on the state of the color scheme: liquid composition, paste or loose pigment:

The first option contains the same components as in the paintwork material (LKM): if you are going to use water-based paint, then the color composition should be the same.
Bulk pigment is inexpensive, but it has a limited palette.
The most convenient option is color paste.

Select suitable color:

You can choose a shade using the catalog - it is in every specialized store. Please note that the shade looks different depending on the lighting.
If the room where you want to paint the walls is light, then give preference to synthetic pigment. Under artificial lighting, colors that contain organic substances look great.
The color scheme of the surface should be in harmony with the background floor covering, furniture. If the floor is made in a green-blue tint, then it is better to decorate the walls in a golden or yellowish tone. With a brown floor surface, it is better to make the color for the walls beige.
The range of wall coverings can be saturated and bright: it is known that juicy shades can lift your spirits. These include juicy green, golden, brown or ocher tones. Please note that blue shades in evening light they appear more faded than in daylight.

The use of colorants or coloring pigments allows you to get any color of the surface. You can use the service offered by building markets. Paint tinting is an opportunity to prepare construction material immediately prior to work. Minus manual tinting - if the resulting composition is not enough, it is extremely difficult to get exactly the same shade.

Material selection

Get new color in two ways - glazing, tinting. Glaze - mixing paints of two colors to get a third. For example, red plus blue makes purple. Tinting - in paint white color dye is added.

There are several rules that must be observed when tinting paint:

Colorants must be from the same manufacturer as the paint.
The color should be selected according to the lighting of the room where the painted surface will be used.

Note! The basis should be not just white, but snow-white paint. Only in this case it is possible to achieve the required shade. For walls, paint “for walls” is selected, for the ceiling - “for ceiling”. These materials are not interchangeable!

Usage organic compounds allows you to get a wide range bright colors. But under the influence of UV they are destroyed. Colorants based on synthetic materials make it possible to obtain a substance that is resistant to atmospheric phenomena. The disadvantage of synthetic materials is the limited range of shades.

Color paints. In their composition, they are close to the coloring liquids for which they are intended - water-based, oily, acrylic, etc.
Pastes. They can be universal or designed for a specific type of paint. In the absence of a binder component in their composition, the proportions should be strictly observed. For water-based materials - their volume should not exceed 20%, for oil - 1.5%, the rest - 5% - 7%.
Powder. To achieve its uniform dissolution, you first need to prepare a working solution based on the substance used - water, solvent, drying oil, etc. Before use, the solution must be filtered.

It is better to purchase tinting liquids packaged in bottles with a narrow neck, syringes. Pigment pastes and powders are more suitable for mixing with tinting machines.

Before purchasing any type of pigment tinting agent, you should carefully read the instructions that come with it.

There are special tinting compounds for varnishes. They give these materials pearlescent, copper, gold and other metallic hues.

Stages

First you need to get "probes".

In jars of a small volume, paint is diluted with the addition of a few drops of a pigment substance. Moreover, the amount of materials used is recorded.
Then it is painted with the colors you like small plot working surface. After drying, it is evaluated under all types of lighting.
The desired shade is determined experimentally.
The material is prepared in the required volume.

Note! When cooking, the coloring composition is stirred, not whipped.

Manual tinting is convenient to use only when painting small areas.

If you need to carry out painting work in large volume, then it is better to take advantage of technological advances. But it must be taken into account that when choosing a color in a building market on a small sample under artificial lighting, it is easy to make a mistake in tone. It is better to have your own sample of the desired shade with you - a piece of wallpaper, fabric.
