Features of dilution with water
Acrylic paints are a water-dispersion mixture that adheres perfectly to almost any substance. The material differs in consistency and color. Water is used very often as a diluent as it is an affordable product.
The technology of dilution with water is quite simple and involves the implementation of several sequential steps:
- Initially, you need to choose the optimal proportion for breeding. It is advisable to dilute in the ratio recommended by the manufacturer. The required volume of paint and water is collected in separate containers.
- When everything is ready, add the diluent to the mixture in small portions and mix thoroughly. If the volumes are large, you can use a construction mixer, which will allow you to get an even consistency. When mixing, foam may form on the surface of the solution. You can use the paint only after it has settled and the solution becomes homogeneous.
Dissolve the paint in water in small portions in order to accurately control the selected proportion and achieve the desired result. There are several popular ratios that are found when mixing acrylic and water:
1: 1 (water: paint). This option is the most optimal and demanded. After mixing, the paint turns out to be thick, which allows to obtain an even thick coating.
- 2: 1. Adding a lot of water makes it a liquid formulation. It can be applied only with a roller. If you do not need such a consistency, then in order for the paint to harden, you should leave it for a while. With this concentration, a thin layer can be obtained. This approach is very often used when decorating living spaces.
- 5: 1 and 15: 1. These proportions are rare. They are mainly used by professional designers. With this dilution, the paint becomes very liquid and almost transparent. With these solutions, it is easy to obtain the effect of translucency or halftones.
What is the Difference Between Thinner and Thinner
Before choosing one of these tools to solve a problem, it is worth understanding their differences and features. The solvent is a volatile organic liquid such as alcohol or ether. It can also be a mixture of these fluids. It is used to dissolve film-forming substances and give the desired consistency to paints.
Thinner also refers to volatile organic liquids used to reduce the viscosity of the paint formulation, thereby achieving a consistency suitable for good application to the surface.
Liquids are quite similar, so they are often confused. Solvents are often used in paint manufacturing and are introduced during the manufacturing phase. The base of the paint and varnish material is a solid or viscous substance. Therefore, the solvent allows you to achieve a form of the composition that is convenient for work. When this substance is added, the paint will remain in a liquid state and will not dry until the surface is covered with it. Due to the ability to influence the structure of the composition, the solvent belongs to rather aggressive products.
The thinners are not as aggressive. Their composition does not dissolve the resin, they only dilute it to the desired degree of viscosity. Dilution is the key task. That is, a change in viscosity, but not in structure, therefore they are more gentle.
Solvents are often used in paint manufacturing and are introduced during the manufacturing phase.
What is better to use, is it possible to use water
When the composition has dried up, the question arises of how to dilute acrylic paints. Due to the fact that they contain quite a lot of water, it can also be used to change the consistency for the better.
If the material is dry, water will not help. When added to a jar, a suspension is formed, consisting of pigments and acrylic particles in a liquid. The material will lose strength, coils of the composition will appear on the surface.
You can dilute acrylic with water. But, only strictly observing certain proportions and do it once. Constantly resorting to this method will not work.

There are many factors to consider when choosing the right dilution mix, including:
- Temperature. The room should have temperature indicators in the range from 15 ° С to 20 ° С heat;
- Composition. You should know what is the degree of purification of the substance, which is planned to be diluted. No impurities are allowed. In the case of water, it must be settled or distilled;
- Proportions. If you make mistakes, then the consistency will turn out to be too thick or liquid. The quality of the material will be spoiled.
You should know what is the degree of purification of the substance, which is planned to be diluted.
In addition to water, thinners and solvents can be used. There are several main groups that are used for paintwork:
- Artistic. They are used for interior decoration and painting.
- Specialized. They are issued for specific areas and take into account the characteristics of these sectors.
- Universal. Can be used with any acrylic paint, regardless of its area of application.
Also, solutions are divided according to the degree of drying:
- Slow. Can be used in high temperature environments. Allows you to slow down the drying of the composition.
- Average. They are used at temperatures from 15 ° C to 25 ° C heat.
- Fast. Can be used at low temperatures, down to -15 ° C.
The latter option is suitable for paints used to paint the facade.
Universal thinners can be used for any acrylic paint, regardless of its area of application.
Choosing exactly what to dilute the composition with, you should rely on the following recommendations:
- When working indoors and painting walls and ceilings, use water as a thinner;
- For working with furniture or wood, diluents are suitable to improve the interaction of paint and wood;
- A solvent is suitable for metal.
It is worth considering the surface on which the composition is applied, and the desired effect.
When working with furniture or wood, thinning agents are suitable to improve the interaction between paint and wood.
What if the acrylic paint is dry?
It happens that due to improper storage at home, even for a short time, the composition has time to thicken or dry out strongly. To remedy this situation, you need to do the following:
- Acrylic mixture differs from simple enamels in that it can be diluted with different degrees of drying of the basic composition. So, with an increase in viscosity, water is simply added to the solution and mixed well. The main thing is to close the container tightly. This rule is also true for those cases when there is a small residue after painting.
- If clots are observed in the composition, then a little alcohol is added to the water. The mixture is thoroughly mixed until the lumps disappear completely. A small amount of solvent is poured on top, the container is well sealed.
It is more difficult to restore the dried composition. For this, a whole range of actions are performed:
The hardened material is removed from the container and broken into small pieces
It is important to exclude the ingress of dirt and dust.
Lumps must be crushed as much as possible.To do this, you can use a piece of pipe or fittings of a suitable diameter.
The resulting powder is poured into a convenient container and filled with well-heated water
The solution is not stirred, but shaken several times. After a minute, the liquid is drained.
A new portion of hot liquid is added, the procedure is repeated.
A special thinner is poured in, the mixture is mixed well until the desired viscosity is obtained. But such a material will no longer have all the properties.
If the paint has time to dry to a stone state, then it is better to refuse to restore it. Although you can follow the previous procedure, which will take effort and time, the resulting composition is best used for utility rooms.
What can be diluted
The marking of any acrylic paint indicates that it must be diluted with water and thoroughly mixed with a mixer before use. This is due to the fact that any mixture on acrylic has an increased density and density. If the instructions are not followed, the material will be difficult to apply. Thick paintwork materials are drawn behind the roller or bakeware. Tools leave a mark that is difficult to repair. In addition, this mixture will not stick so well to the wall. The formulations can be diluted with different substances.
Water solution
Most often paintwork materials are mixed with water before work, because it is the main component of the mixture. Depending on the type of work, the liquid is added in the following proportions:
- 10% by weight of the substance - this small volume makes it possible to prepare paintwork materials well for finishing application;
- 1: 1 - obtaining a composition for rough application;
- 1: 2 is a liquid substance suitable for the repair and restoration of walls.
- 1: 5 is a liquid substance used for application to structural surfaces.
Special means
Pigments are special agents used to dilute acrylic paints. All acrylic based water emulsions are available in a white or clear base. The combination of dyes will give the building material a new shade to taste. Pigmentation can improve the physical characteristics of the material.
Solvents
Acrylic enamels are diluted with special solvents, because with machine painting, dilution with water does not provide the necessary performance for work. In addition to elasticity, when applied, solvents can increase the level of gloss or, conversely, impart a matte effect.
Other paints
Sometimes there are cases when there are remnants of several types of paints at once. The reluctance to go to the store for acrylic paint or the inquisitiveness of the mind forces people to experiment, mixing different compositions. In this case, you need to look at the binder from which the paintwork material is made. In addition to acrylic, there are:
- silicate;
- silicone;
- oil.
If there are mixtures of acrylic, but of different colors, you can make one paint from them by adding water. However, the original tone will change. It is difficult to predict what shade will result from such a mixture.
In other cases, it is not recommended to mix materials of different composition. Because they are incompatible and will not dissolve into each other. As a result of such an action, an unusable paintwork material will be obtained. During application, it will be noticeable that the liquid has separated into layers. And after application, there is a high probability that the coating will crack and peel off in a short period of time.
How can you replace a special solvent for oil paints
If for some reason it is not possible to use the ready-made solvent sold, then you can replace it with other options. The most common remedy is to use regular gasoline.
The most common remedy is to use regular gasoline.
Artists know exactly how to make oil paint thinner.They like to use ordinary vegetable and linseed oil, the advantage of such an improvised product is the lack of smell, but the disadvantage is the long drying time. Also, an odorless option can be used to mix white spirit with turpentine. The proportions are made equal.
The main thing with self-dilution is to introduce the agent in small portions in order to check how the composition has changed, whether the properties have been violated. To do this, apply a small amount to the canvas or material to see how the product will stick to the surface.
Artists love to use common vegetable and linseed oil.
Dissolving oil paints can be used for different purposes. In this case, the dilution rules specified by the manufacturer should be observed in order to obtain the desired result, and not to face the problem of changing the properties of the product. For artistic paints, slightly different solvent options are used compared to building paints. It is better to select products that do not emit an unpleasant odor, and they comply with safety rules when working.
Selection of substance
Given the variety of uses for acrylic, the choice of dilution method and type of fluid often differs. Liquid paint is required to paint furniture or create decor. This approach does not allow to eliminate irregularities and defects. Water is more commonly used in this area, and solvent for alkyd paint should be avoided.
But we will pay attention to what kind of solvent to dilute car paint. There are 2 leading solvent types that are typically preferred by professionals:
- Water. The liquid is part of the paint and in the correct proportion will definitely not harm the quality. The creation of optimal density is possible without the use of aids. The method is cheaper and easier to use.
- Special solvents. If you make a choice of how you can dilute acrylic paint, except for water, you need to take into account the dependence of the quality of the solvent on a particular manufacturer. Usually, the recommended dilution liquids are reported on the packaging or official website. Such formulations are popular due to the ability to thin thick paint and additionally give a matte or glossy appearance.
If, for comparison, consider how to dilute alkyd paint, then only a special solvent is used. Many manufacturers make the formulation suitable for reconstitution with universal solvents, while others create specialty liquids and sell them separately.
What are acrylic paints used for?
The paintwork material requires dilution before use. The thick mixture must be diluted to obtain a solution of the required consistency and obtain a smooth and correctly painted surface. Acrylic paint can be diluted:
-
By water
... The easiest way to get it is to dilute the acrylate. The downside is that the dried composition cannot be washed off either from tools or from stained surfaces. -
Solvents
... Allows to influence the final properties of acrylic paint. They can give the final composition either a gloss or a matte finish. It turns out that solvents, unlike water, need to be selected according to the desired result. -
Paints
... Acrylic paints are mixed with each other to obtain new shades and colors. Such manipulations are rarely resorted to, since the available variety of the palette is quite enough to meet any needs. -
By special means
... There are quite a few liquids that are designed to dilute acrylic paint to the desired consistency. They are recommended for use by manufacturers.
The specific agent is selected taking into account the desired result.
The better to dilute the paint PF 115
To understand the nuances of dilution, you need to learn about the components that make up the paint, and its features.PF 115 is an alkyd enamel, its field of application is wide, it can be used to paint wooden, metal, plastered, concrete surfaces.
Its popularity is also due to its low cost. It includes:
- Alkyd varnish;
- Solvents;
- Pigments;
- Pentaphthalic varnish (precisely because of the presence of this varnish in the composition, the abbreviation PF is present in the name). This varnish is a mixture of resin with vegetable oils, rosin, glycerin.
By mixing varnish with alkyd enamel, PF 115 is obtained.
In addition to its low cost, it has good characteristics and is able to protect metal surfaces from rust formation and from harmful atmospheric influences.
The paint has good characteristics and is able to protect metal surfaces from rust formation.
Before thinning the paint PF 115, you need to read the instructions on the package. Where the recommended solvent will be indicated. This is due to the fact that the production of different brands may differ slightly. In production, they go through some stages of preparation, but they are often released for sale with the addition of solvents. In such cases, a specific type of diluent may be written on the packaging, which is compatible with the type already added.
Which solvent for PF 115 is suitable:
- Turpentine;
- White-spirit;
- Solvent.
You can also use a number of other types, they will be discussed later.
They begin to dilute immediately before the start of staining, you should not do this in advance.
How PF 115 alkyd enamel differs from acrylic paints
When choosing a coloring agent, there is a desire to compare it with others to make sure that it is the one that is best suited for specific work. Now two types of paints and varnishes that are popular will be disassembled.
The composition of alkyd paints includes:
- Drying oil;
- Glyphthalic and pentaphthalic varnishes;
- Oil-phenolic varnish.
For a better understanding of the differences between alkyd and acrylic paints, it is worth understanding the positive and negative qualities of both.
The main difference, of course, lies in the basis of the composition. So, speaking about alkyd enamel PF 115, the following advantages can be distinguished:
- Has good performance in protecting surfaces from harmful effects;
- Complete drying occurs in a day;
- Budgetary price;
- Large assortment of colors and shades;
- When painting, it is enough to apply two layers, sometimes you can limit yourself to one, which also makes it more economical;
- Resistant to moisture, temperature extremes.
The disadvantages are:
- Toxicity and fire hazard, however, after drying, the paint ceases to be harmful. During drying, it is better not to enter the room where the painting work was carried out and the painted object is located for a day;
- The service life is lower than that of acrylic.
Has good performance in protecting surfaces from harmful effects.
Acrylic paints also have their positive properties:
- Long service life;
- Non-toxic;
- High UV resistance;
- Able to withstand high temperature performance.
The downsides are:
- High price;
- It takes a long time to dry completely;
- It's hard to choose a good lineup.
Also, to dilute alkyd paint, you need to use solvents, and for acrylic paint, plain water is suitable.
Able to withstand high temperature performance.
How to dilute?
PF or GF enamels are sold ready for application and with the degree of density that best matches the composition of the material. However, if the formulation is to be diluted, only the smallest amount of diluent must be added, for example:
- If external painting is required, then the finished paint should be diluted by adding a thinner in an amount of not more than 3% of the total enamel volume.
- For interior work, the finished paint should be diluted with the amount of thinner no more than 5% of the total volume.
- If the composition is diluted with a large amount of thinner, then the enamel flows (in particular, from vertical planes), forms drips. In addition, the performance of the paintwork is reduced.
It should be noted that the material composition and percentage of ingredients in painting materials is not accidental and is the result of many years of experience. Therefore, the desire to improve the quality of the painted surface by adding a thinner in an arbitrary amount, often leads to a deterioration in the characteristics of the coating.
Thinning technique
The most important parameter in paint dilution is viscosity. The quality of the coating will depend on how correctly you select the viscosity of the composition. Too thick material will not allow filling all the small pores and roughness, and it is impossible to get rid of them even with careful surface treatment.
Many finished enamels are now on sale. They are already diluted and ready to use. Nevertheless, even using the factory compound, it is necessary to dilute it with a solvent for better application to the surface of the structure. This will also provide quick drying and added corrosion protection.
All solvents are divided into three groups depending on the rate of evaporation. Each climate requires the selection of a special solvent. It depends on what the coating will be after drying. The main types are:
- fast - used in low temperature conditions;
- slow - suitable for work in hot weather;
- universal - used under any conditions.
Surface painting is carried out with a spray gun, so it is necessary to select the density that the equipment can handle
The main parameter that you need to pay attention to when working is temperature. Spreading and drying of paint completely depends on this indicator.
At the moment, there are many thinners produced specifically for work at different temperatures. Unlike solvents, they are more expensive but more effective.
It is not recommended to determine the amount of diluent by eye. Mixing should be carried out in small portions and after each time measure their content in the paint. Therefore, inexperienced people are better off using universal solvents suitable for any temperature regime.
On each can of paint, the manufacturer indicates the correct ratio of solvent and composition. The first step is to adhere to the recommended parameters. However, depending on the date of manufacture and the type of solvent chosen, the mixture does not always get the required consistency. Therefore, it is worth doing a few experiments with small portions of materials.
On each can, the manufacturer indicates the correct ratio of solvent and composition, but this does not always allow achieving the required consistency
Where to dilute acrylic paints
As mentioned earlier, it is recommended to prepare a small amount of dye for dyeing. For this reason, it is better to reanimate the dried composition not in the jar itself, where the entire volume is located, but in another container.
The reason is also the possibility of leaving the entire volume in a closed container, because the addition of a thinner can lead to the loss of the original properties, color brightness. Therefore, it is better for this purpose to choose a palette where it will be possible to adjust the components without rushing. Then it will be easier to get the required brightness.
For a beautiful coloring, a different level of liquid consistency may be required (it will be used as a ground or first layer, or in places where shades change). You may also need to stir several colors together to get a new shade.
It is better for this purpose to choose a palette where it will be possible to adjust the components without rushing.
How to keep paint from drying out
It is very important to understand why the paint has dried. The fact is that acrylic is based on water, which evaporates a little even with the lid closed.
This, in turn, leads to polymerization. You need to know that when dry, the properties of the mixture also evaporate. In order not to bring the stock to this state, you need to follow simple rules:
- It is strictly forbidden to dilute paint or add coloring pigments in a common can. After all, you do not know if all the material will be used up. Better to pour the required amount into a separate container and dilute in it.
- Remember, water from acrylic evaporates quickly, so close the lid on the tube or can as tightly as possible. This will slow down the drying process.
- Quite often, the lid is glued to the base of the can. To prevent this, after work, immediately clean the edges of the container from the remaining dye and only then close the lid.
- Do not store paints at high temperatures. This helps to neutralize moisture and properties.
How to determine paint viscosity using a viscometer
To determine the viscosity of paint, varnish or soil, we take a viscometer and completely fill it to the brim with the selected material, while closing the hole with our finger, measure the time using a stopwatch, while opening the hole in the viscometer, which was previously kept closed. We follow the stream flowing through the hole. As soon as the jet stops flowing in a single stream and turns into drops, the stopwatch must be turned off. The time in seconds, which is recorded on the dial, will be the measured viscosity, indicated in DIN seconds.
For finished paints, the viscosity is indicated on the can or in the technical specifications for the paint and varnish material. However, it is not always worth trusting what was written, sometimes it is worth rechecking this data after verification, if the data indicated on the bank and the calculations performed using the viscometer differ, for example, the viscosity turned out to be higher than the recommended one, then such paint will need to be diluted. Sometimes the viscosity of the paint is determined "by eye", however, relatively accurate data in such a determination can be achieved only with extensive experience in painting work.
When diluting the paint, measuring rulers and containers are used to maintain the proportions. The measuring container is part of the toolkit with which the paint is diluted and is a transparent plastic jar on which proportions are marked with the help of serifs. Dilution of paint can be done using an ordinary plastic cup, however, before work, it must be checked for solvent resistance - pour a small part of the specified liquid into it and after a while see if the solvent has leaked out. If everything is in order, no chemical holes have formed in the glass, then you can safely use this glass to dilute the paint.
After diluting the paint, it is imperative to get rid of insoluble elements and debris. To do this, it is filtered through a sieve, or gauze folded in several layers is used as a filter.
Types of paints
1). Water-based paints
Water-based paints and varnishes consist of pigment, water and the material that binds them. This type of paint includes watercolor, gouache and acrylic, which is the most popular and demanded because of its waterproof properties. Acrylic paints are used both indoors and outdoors, dry quite quickly and are considered environmentally friendly. This purity factor is due to the fact that for dilution acrylic paints on water-based use clean cold water.
2). Oil paints
They are great for outdoor use due to the fact that they create a protective layer that does not allow moisture and water to pass through. Oil paints are made from all kinds of essential oils and dyes. That is why, when diluting oil paints, white spirit, drying oil and oil-resin varnish are used.
3). Enamels
Enamels are represented by the largest variety on the paint market. This is due to the fact that they can be diluted with almost all solvents: turpentine, white spirit, gasoline, solvent, xylene, solvents R-4, R-6, No. 646 and No. 645.
Types of paints
1). One-component (1K)
This type includes base enamels, they are diluted only with a solvent.
2). Two-component (2K)
This type includes acrylic enamels and varnishes.
The dilution technology is as follows: first, a hardener is added, after which the composition is brought to the required viscosity using a thinner.
The main difference between two-component paints and one-component paints is polymerization, i.e. drying. One-component paints dry naturally, while two-component paints dry by reaction with a hardener. Acrylic interacts with the hardener, as a result of which the chains of molecules are connected - the material polymerizes.
The solvent in two-component paints is used only to obtain the desired viscosity. If you add more hardener to the material than required, then the required hardness may not be obtained, because the number of molecules for bonding is greater than the number of polymer molecules from acrylic.
It is important to remember that paint drying is temperature dependent. Trying to adapt to it, you can not guess and make the solution either too thick or too liquid, which is fraught with loss of gloss, drips, increased shagreen
To prevent this from happening, three types of diluents are used, depending on the temperature regime:
- fast, applied at a temperature of 15-20 ° C, evaporate in a short time, accelerate the drying of the paint;
- normal, used in good conditions for painting at a temperature of 20-25 ° C, help to dry, prevent drips;
The nuances of using a solvent
There are no special rules for the use of a solvent. All recommendations depend on the purpose of the staining. Manufacturers produce special solvent compositions that can add new properties to paintwork materials. With their help, you can give them dullness, shine, change the consistency of the mixture. All these characteristics of the solvent are indicated on its packaging. It should describe exactly what a particular composition is suitable for. The fresher the solvent is, the better the result will be.
A small amount of solvent is enough to keep the color vibrant and rich. To obtain a transparent effect, its volumes are increased several times.
If the paint will be applied with a spray gun, the material needs to be made more fluid. For this, only special types of solvent are suitable. It is they who make it possible to give the mixture such a consistency so that the spraying occurs in an even layer.
It is important to understand that the use of such a substance can provoke some changes in the characteristics of paintwork materials, both for the better and for the worse. This applies to shade, strength, drying and appearance.
It has already been noted how solvents are separated according to the drying rate and how they are affected by the temperature index in the place where the compositions are mixed. This is important to consider when choosing the right product.
If the paint will be applied with a spray gun, the material needs to be made more fluid.
