Car paint has thickened, how to dilute it

How to thin car paint?

Acrylic paints flooded the market, reducing the position of other varieties. Car experts recommend using acrylic for painting most elements of the body, and sometimes the interior. The paint is based on water, it quickly evaporates and the mixture hardens. The substance can dry out even before application; if storage conditions have been violated or the shelf life has expired, it is also recommended to dilute the thick paint. Many people prefer to buy new liquid rather than dilute acrylic paint; in reality, the dilution process is easy and does not require much time.

Features of using water as a solvent

To dissolve acrylic, take cold purified water and a container in which to dilute the paint. Then the proportion is selected experimentally:

1 to 1: the resulting paint is suitable for creating a base layer, since it is not very thick, adheres well to the surface and evenly paints parts.
1 to 2: the result is a coloring composition that tends to penetrate well into the structure of the soft part of the roller and does not spread. This proportion gives a smooth surface with a thin layer.
1 to 5: liquid structure leading to loss of original color. Painting surfaces without adding pigment is allowed in the case of multi-layer processing.
1 in 15: more like slightly colored water. This proportion is recommended for creating a gradient (a smooth transition from one color to another).

To maintain the ratio of parts, water can be measured using a graduated glass or a large-volume syringe. The liquid is added to the acrylic paint gradually, the resulting composition must be constantly stirred.

Decorative coating and its components

The paint is easy to apply on most surfaces, providing adhesion and sufficient durability. The problem is often the inappropriate consistency of the paint product. Thick paint creates an uneven layer; in some places the saturation is excessive, while in others the original color of the body is visible. The easiest way to solve the problem is to dilute the substance. Having decided what you can use to dilute acrylic paints and take a readily available liquid for dilution, it will not be difficult to create a high-quality coating.

Acrylic paints are easy to apply on most surfaces

The paint always contains 3 main components:

The most important component is an emulsion made of polymer materials, containing acrylic. High technical and performance qualities and ease of application allowed the paint to be used in many areas. Advantages of the composition:

Paint application does not require professional skills

Thinning is an important procedure to ensure that the car is painted evenly and with high quality. In some cases, the addition of liquid is optional, but in some situations it cannot be avoided.

Information on how to dilute paint for spray guns and other painting methods is applied to the container, but specialists are additionally based on current tasks. For the rough layer, a thick solution is often used, and the final coloring is performed with a thinner substance. Everything here is individual, but there are some norms that are not recommended to go beyond.

Types of hammerite paints

There are the following types of enamel:

Hammer. In addition to the main components, this paint contains aluminum shavings, which gives the painted surface the appearance as if it had been beaten with a hammer. This feature helps create the now fashionable “aging effect” on a variety of interior items, and is also used for processing metal products - fences, fences, industrial equipment, etc. Main characteristics:

high degree of adhesion to rust;
increased hydrophobicity;
quick drying;
variety of shades.

Smooth, compares favorably with coloring compositions from other manufacturers with the following advantages:

the composition includes active anti-corrosion components, thanks to which hammerite paint provides long-term protection against rust;
can be applied to areas affected by corrosion;
high degree of adhesion and good hiding power;
has a “3 in 1” effect - can be used as a primer, sublayer and finishing layer;
easy to apply;
dries quickly;
the ability to create a glossy or semi-matte texture.

Hammerite hammer paint

Regardless of the type, hammerite paints are suitable for protecting, decorating and giving the desired color to both metal surfaces and wood, glass, and plastic.

Peculiarities

An important feature of acrylic is its naturalness; the environment does not suffer from the use of an automotive composition. There are no fumes or strong odor from the paint. The advantage of acrylic is the variety of shades; it is easy to obtain any color using special pigments in the appropriate dosage.

Due to its water base, the substance is resistant to fire. The listed qualities contribute to the use of acrylic in residential premises and small spaces. Water evaporates quickly, causing the material to harden faster than its analogues. An important advantage of the composition is that acrylic can be diluted even after drying, so the substance will return to its original form. You just need to know how to dilute acrylic paint and the recommended dilution rates.

Features of acrylic

Acrylic paints are a type of water-based solutions. They are produced in the form of a thick consistency of various colors. In order for the solution to be applied evenly to the surface of the material, it should be diluted beforehand. Acrylic paint consists of several components:

Dye. The pigments are various types of powder, which are crushed into very small particles. This element is made from natural or synthetic substances.

Acrylic resin. It is used to connect all components together. It is the resin that, after drying, forms a durable film that holds the pigment on the surface of the material.

Solvent. Many manufacturers use ordinary water for this. But some types of acrylic paints are made based on organic solvents.

Fillers. Various substances are used here that can change the physical and decorative properties of paints. With their help, acrylic is given strength, durability or resistance to moisture.

The popularity of acrylic paints is due to several of their advantages:

Versatility. Acrylic can be used to paint almost any material. These paints are not used only for a few types of plastic, which are almost never found in everyday life.

Practicality. These solutions are relatively easy to apply, so even beginners can use them. In this case, a uniform layer is formed on the surface. Safety. The paint does not emit any harmful substances into the air, as it consists of safe components. There is no unpleasant odor during the application period, which allows you to work with acrylic without a respirator

The paint does not burn, which is important for domestic or industrial premises. Resistance to moisture. Acrylic resin dries to a durable layer that easily repels water

Therefore, these paints can even be applied to building facades.

Selection of substance

Given the variety of uses of acrylic, the choice of dilution method and the type of liquid often differ. To paint furniture or create decor, liquid paint is required. This approach does not eliminate unevenness and defects. In this area, water is more often used, and solvent for alkyd paint should be avoided.

But we will pay attention to what solvent to dilute car paint with. There are 2 leading types of solvent that are usually preferred by professionals:

If, for comparison, we consider how to dilute alkyd paint, then only a special solvent is used. Many manufacturers make the composition suitable for dilution with universal solvents, while others create special liquids and sell them separately.

There is an opinion that thinking about how to dilute car paint is an absolutely unnecessary point. They say that it is already fully prepared for further use. Some of the varieties of automotive enamels, however, already contain a certain amount of solvent. However, it is worth remembering that during storage (and the paint did not reach you immediately from the factory), all such materials thicken. It’s not for nothing that they often come with thinners: it’s wiser to dilute the composition right before use, without guessing how much solvent has evaporated since the enamel was packaged in a jar.

Solvent and its use

The solvent is sold in bottles and is a clear, colorless liquid with a specific aroma. Most companies simultaneously sell acrylic-based paints and special solvents. Their use is justified to impart additional decorative properties to the coating. Mobihel, Duxone, Body, Kartex, etc. have a similar approach.

Solvent for acrylic paints Bulmat

Using a special thinner, it is possible to achieve:

Metallic painting is popular in cars; the required solvent is available in most stores. Sold in jars, you can select them in a store or on a thematic forum. A solvent is often used to speed up the hardening process, which helps get the job done in a short time.

When choosing an option with what and how to dilute car paint with special properties, you should prevent a decrease in the main characteristics of its composition. An example is “Polistil” paint with increased temperature resistance; if you select any solvent with a tendency to burn or deform from heat, the coating will lose up to 40% of its qualities.

There are several ways to distribute such liquids, the most common classification is by drying speed:

Thinner for acrylic paints Mr. Color Thinner 1

The key influence on the characteristics is the ratio in which the composition is planned to be diluted. The range of output liquids obtained varies greatly; they are selected taking into account specific requirements. You can paint with acrylic paint either in an almost transparent layer or in a very rich color.

Features of automotive acrylic paint

The composition of this paint is based on acrylic resins of synthetic origin. They provide high performance characteristics for the applied coating. In particular, such resins do not age, retain color and do not fade in the sun, and are able to withstand temperatures within 180 degrees Celsius. Also, acrylic resins are inert to acids, alkalis, water and thermoplastic.

Acrylic-based resins are a colorless material; to obtain paint, a pigment with the desired tone is usually added. In addition, varnish is also made from these materials, which is also applied as a protective coating on the car. After drying, this paint forms a polymer film that protects the metal from corrosion and partially from mechanical damage, as well as environmental influences.

To paint a car with acrylic paint, two-component paint compositions are usually used. An additional hardener is added to the base enamel in a ratio of 1:3 or 1:4. This helps reduce the drying time of the coating by several times. Also, the paint itself is diluted with a solvent in a proportion of 10% - 20% of the total volume of material (paint and hardener). To prepare the composition, it is better to follow the instructions indicated on the package. When purchasing consumables, it is better to buy paint, varnish and thinner with a hardener from the same manufacturer.

Surfaces that are painted with acrylic enamel do not need to be varnished. But if you wish, you can do this and in addition to an additional protective layer for the coating, you will get the effect of depth. The varnish is also applied in 2 - 3 layers.

Both acrylic-based varnishes and paints come in two types of hardness: soft (MS), hard (HS). Soft varnish and paint are applied in several layers; they are easy to polish, but the strength of the layer itself is lower. When using hard varnish and paint, they are applied in 1 - 1.5 layers and it is more stable and reliable.

As mentioned above, in order to obtain the desired consistency of the material, you will need to use a solvent for acrylic paints. It is also used to prevent paint from thickening until it is used. When the coating dries, the solvent evaporates.

If you use acrylic-based paint, you also gain in time, since it dries quickly and the time required for painting work is minimized. Thus, a drying period of 5–15 minutes is allocated between layers; when applied wet, the highest degree of adhesion between layers of paint is achieved. Pay attention to the temperature in the working environment, if it is above 20 degrees Celsius, then the drying period is reduced, and if it is lower, then the material takes longer to dry, and without taking this moment into account, paint sagging and smudges may form.

How to breed

The dilution method is much simpler than enamels, but depends on the method of application. If the painter paints the surface with a spray gun, the liquid becomes more diluted.

There are many solvents available, but you should choose ones that are suitable for metal surfaces. They are purchased at construction or automotive stores. If you plan to use water, it must be distilled and free of additives, since acrylic is somewhat more demanding than enamels. When in doubt about consistencies or types of solvents, it is recommended to do trial mixing in small batches.

Today, several basic proportions and methods have been developed for diluting car paint:

Solvent for acrylic paints X-20A

All paints are sold in the form of a thick mixture, so the question of how to dilute paint for a spray gun is obvious and justified. If you want to achieve a uniform layer using a sprayer, it is better to use liquid options - from 1/2 to 1/5.

Painting with hammer paint

In most cases, enamel does not require baking at elevated temperatures - it is applied at normal room temperature. In addition, the use of putty and primer can be avoided. The need for the latter is eliminated by the content of epoxy resin or anti-corrosion additives in the enamels under consideration. Leveling the surface is achieved by applying several layers of paint: the high density and thickness of the layer allows you to eliminate minor unevenness.

It is not recommended to dilute enamel that contains a solvent further, otherwise it may not dry completely or dry incorrectly. However, the solvent recommended by the manufacturer or included with the paint can be replaced to enhance the surface relief. Some solvents contain additional corrosion protection or allow you to edit the color of the enamel.

When using a roller or brush, two layers of paint are enough, but if the car is painted with a spray gun, 3-4 layers are required. The nozzle diameter recommended for the sprayer is 4 mm, the working viscosity of the material is regulated by a viscometer. Applying enamel in two layers will require an intermediate drying time of 20-30 minutes, and spray application will require 15-20 minutes between each layer. At normal humidity and temperature, final drying is achieved with hammer paint after a few days (minimum 2, maximum 5). After drying, the painted surface of a car becomes so hard that it can only be sanded with great difficulty, but there are two substances with which this enamel reacts poorly: the enamel does not lie on top of the acrylic primer and is easily corroded by brake fluid.

Which solvent to choose for car paint

Car painting jobs require attention and knowledge. To make a car look beautiful, it is necessary not only to carefully prepare the surface of the car body, but also to choose a high-quality paint coating. Moreover, the material must be prepared correctly. To achieve a better result, a special car paint solvent is added to it.

Which paintwork to choose for a car?

There are several types of paints that are used for painting a car. Today, four types are most often used:

acrylic enamels, which have the ability to dry quickly, forming a durable, shiny layer;

To choose the right solvent, you need to know the composition and properties of the paint used.

alkyd car paints that require long-term drying and form a surface resistant to mechanical or chemical influences;
nitro enamels, the coating of which has low resistance to external factors; one of the most popular nitro paints is synthetic enamel with a metallization effect (metallic);
water-based paints, which have been used only recently, but are already gaining popularity due to their environmental friendliness.

Each owner must decide for himself which material to choose for painting a car based on its properties or cost.

Types and features of the choice of solvents and thinners for automotive paints

All existing types of solvents can be divided into several groups, each of which differs from each other in the rate of evaporation. The solvent that will be added to the car paint is selected depending on climatic conditions. There are 3 types of funds:

Paint diluted with a solvent is applied using a spray gun. In order for the coating to be smooth and uniform, the degree of thickness of the product should also be selected so that the equipment can work effectively.

Important! When working with paints, it is necessary to take into account the outside air temperature. This is the main parameter on which the quality of the future coating depends.

Manufacturers of paints and varnishes produce several types of special thinners, which differ significantly from solvents in their effectiveness. And this difference is significant. The diluent is simply added to the product, thereby diluting it to the required concentration.

Types and composition of enamel

Any industrial automotive paint consists of the following components:

After applying auto enamel to a part or body structure element, the solvent gradually evaporates, leaving a durable and strong composition of color pigment and binder. The long service life and impeccable performance of the selected automotive paint are determined by the degree of its hardness and elasticity.

Depending on the chemical composition, there are several types of auto enamel, which is important to consider before choosing a solvent:

Tips and tricks for proper paint dilution

There are a huge number of paints and varnishes, but only some of their representatives are used to paint a car:

All of them differ from each other in performance characteristics, but at the same time they are effectively used by car owners. For a 100% high-quality result, these products are diluted with solvents. What solvent should you use to dilute car paint?

Acrylic paints

This is a two-component liquid, which contains a thinner and a hardener. The desired color is achieved by applying a certain number of layers of material.

For acrylic paints, a specialized automotive solvent is used, which is more expensive than conventional organic solvents (646, 647), but it is worth it. If such a product could not be found, then you can use its analogue - solvent 651 or P 12.

Alkyd paints

Such products are rarely used for painting car bodies, only because they require a more careful approach. The resulting surface should be varnished and polished, but the finished products are distinguished by high performance characteristics and good appearance. The coating prevents the formation of corrosion and performs well in adverse conditions.

For dissolution, white spirit, gasoline, solvent, turpentine and its mixtures are used. There is a universal solvent P 4, but it is better to choose according to the product labeling.

Nitro enamels

They have a mirror effect, for which they have received wide appreciation from car enthusiasts. The body, painted with nitro enamel, differs from other cars in its gloss and metallic sheen. The only significant drawback is toxic fumes during painting work, which are harmful to human health.

Before application, the body surface must be perfectly cleaned and prepared for painting. Nitroenamel dries quickly and lasts quite a long time. It is diluted with organic products, for example, transparent 646.

Advice. This solvent is highly flammable and belongs to the category of aggressive solvents, so it must be handled with extreme caution. To play it safe, you can use the universal product P 4.

Water-based paints

This type of paint is considered the most suitable for painting a car, although it requires expensive equipment to achieve maximum effect. Such products are environmentally friendly and have a number of advantages:

The only negative is the long drying time. Water-based paints are dissolved with plain water or alcohol.

"Pros" and "cons" of using paint

Like any product, this paint is endowed with positive properties, but also has negative aspects. The advantages include the following:

To paint the surface, you need to make a minimum of preparation; For painting you need a minimum of tools, including just one stripper; Any beginner can handle the processing process; you don’t have to pay for the services of specialists; It takes only three hours for the layers to dry, which will significantly affect the repair work; Obtaining a water-repellent and dirt-repellent coating is possible thanks to the silicone included in the composition; Prevents the appearance of rusty areas; Any surface structure that is selected from the proposed range - matte, semi-matte, glossy - will look attractive on the surface; No harmful or unpleasant odor, which is especially important when you have to work inside a building.

The negative side is the inadmissibility of covering a surface that has a layer of bitumen paint.

If it is not possible to determine what material was used previously, then you should paint a small area with paint and wait for the material to react. There should be no swelling or cracks on the surface.

It takes only three hours for the layers to dry, which will significantly affect the repair work.

Features of metallic paint dilution

Metallic is considered a complex paintwork and requires precise application technology. The product is widely used for painting vehicles (cars and motorcycles). The surface has a metallic reflective sheen. This effect is explained by the presence of special aluminum powder in the material. The finished coating is not affected by corrosion, and the result will please the eye for a long time. However, mechanical stress and disruption of the integrity of the coating will ultimately lead to its destruction. The paint does not fade under the influence of ultraviolet rays of the sun.

The quality of the coating depends on the degree of viscosity of the material, so the solvent for such paint is carefully selected. A product that is too thick can harm the result because it will not be able to completely fill the rough surface of the car body. Modern metallic paints and varnishes are diluted directly by the manufacturer and are ready for application. The cost of such materials is much higher than others, however, the quality of the coating will amaze with its splendor and beauty.

There are the following types of enamel:

Hammer. In addition to the main components, this paint contains aluminum shavings, which gives the painted surface the appearance as if it had been beaten with a hammer. This feature helps create the now fashionable “aging effect” on a variety of interior items, and is also used for processing metal products - fences, fences, industrial equipment, etc. Main characteristics:

high degree of adhesion and good hiding power;
has a “3 in 1” effect - can be used as a primer, sublayer and finishing layer;
easy to apply;
dries quickly;
the ability to create a glossy or semi-matte texture.

Hammerite paint
Regardless of the type, hammerite paints are suitable for protecting, decorating and giving the desired color to both metal surfaces and wood, glass, and plastic.

Preparation of enamels and varnishes, determination of their viscosity

Cocktails are different and not all of them are intended to be taken “on the chest”. The paints and varnishes that we use to restore a car's paintwork are also cocktails - properly prepared mixtures of several ingredients. And since we strive to ensure that the restored car (fender, door) after repair sparkles brighter than a new one, and the paint lies evenly, then our “paint cocktail” must be prepared competently, carefully and carefully, and not concocted anyhow.

Transition solvents

In addition to universal ones, there is also a solvent for transition. They are not intended for thinning varnishes and enamels. Their purpose is to create an invisible transition between old and new paint or varnish. To do this, apply the transition solvent from a paint sprayer or aerosol can onto the dry “spray” in the transition zone of the varnish or acrylic paint.

It is extremely important to note that the solvent for transferring over varnish or acrylic paint and for transferring over the base, also called “Binder,” are completely different products. A paint binder is something like a transparent base. It is used so that the metallic grain does not stick out like a “hedgehog” in the transition zone, but “settles down” correctly, which will ensure a high-quality invisible transition.

Ingredients

First of all, let’s decide on the type of our “paint cocktail”: will it be regular acrylic enamel (which is less likely), or metallic or pearlescent paint (most likely).

Regular acrylic enamel is two-component, with a hardener. The “ingredient kit” for such materials consists of three jars. For example, a liter of paint, half a liter of hardener and 100-150 ml of thinner. That is, when buying a liter of paint, you actually get about 1.6-1.7 liters of diluted paint.

This must be taken into account when selecting paint: some laboratories indicate prices for “thick” paint, and some for “thinned” paint. The difference, as you yourself understand, is huge.

In the case of “metallic”, the base paint is necessarily covered with a transparent varnish on top - without it, spectacular coatings look inconspicuous, and the weather resistance of two-layer coatings is much higher. Transparent varnish, like acrylic enamel, is two-component, with a hardener. But the “base” does not need a hardener - it is one-component.

Thus, the “set” for two-layer coatings already consists of five cans. For example, a liter of “base”, 500-700 ml of thinner for it, a liter of transparent topcoat varnish, half a liter of hardener and 100-150 ml of varnish thinner - a total of 3.3 liters! At the same time, the diluted paint itself was no longer there, the same 1.7 liters.

How to mix paints correctly.

Beaker
Measuring ruler.

Each has its own advantages and what to use is purely everyone’s choice. The measuring ruler is reusable and will last a very long time, unlike a measuring cup. Measuring rulers are double-sided (each side has different mixing proportions). Basically like this: 2:1 and 4:1 and another option is 3:1 and 5:1. How to use the measuring ruler and glass in the photo below, there is nothing complicated about it. Before mixing paints, be sure to read the instructions on the packaging in what ratio to dilute the material. Below I will tell you in what proportions to mix different paints.

Mixing acrylic paint "acrylic":

For Vika paint this is a 4:1 ratio with hardener and 20%-30% thinner. And for Mobihel 2:1 with hardener and 10% -20% thinner.

Mixing base:

The base paint is generally mixed 2:1. That is, the base itself and half of it is the solvent. It can also be mixed 1:1.

Mixing varnishes:

The story with varnishes is almost the same as with acrylics. The varnish is diluted 2:1 with hardener and thinner from 0% to 20%. Depending on what viscosity you need it. All the above mentioned figures are approximate and may vary depending on specific needs, type of work, and application technique. In general, read the instructions before use and there will be no problems.

To accurately determine the viscosity of paint, there is a special tool called a viscometer. The operation of the viscometer: the viscometer is immersed in paint, taken out and timed for how long it takes to empty. As soon as the stream begins to drip, the stopwatch is stopped.

Measuring viscosity

Any painter should be able to control such a vital indicator as viscosity. For what? So that it corresponds to the recommended size. Again, why? To evenly apply the material to the surface and obtain a coating of the required thickness with the required properties - beautiful and durable.

“Viscosity” (from Latin viscosus - sticky, sticky) is a value characterizing the fluidity of a liquid.

Why measure viscosity?

For more details, use the example of filler soil. The surface on which we apply it has various kinds of micro-irregularities left after preparation (grinding marks, pores, etc.). In other words, protrusions and recesses. From the deepest to the highest point - approximately 50 microns.

So, if we apply too liquid a filler to this surface, its thin film will not be able to cover these irregularities, and even with a margin for grinding (by analogy: if you put pebbles on the bottom of a jar and pour water without covering the stones “overall” ). As a result, the surface will remain uneven, and the soil, by and large, will be wasted. You have to do extra work - reapply the filler, spending twice as much time on repairs.

Let's take the opposite situation with applying too thick filler. It would seem that there certainly shouldn’t be any problems here. No matter how it is. A filler that is too thick and non-flowing, again, will not be able to properly fill all the micro-irregularities - its penetrating ability is too low and it is simply not able to flow into these small depressions (just as a soccer ball cannot fall into a golf hole).

The coating turns out to be loose, poorly adhered to the surface, and subsequently the filler begins to peel off. Not a very rosy prospect, but the troubles don’t end there. A filler that is too thick will not be able to spread over the surface in a smooth layer; increased shagreen is formed, which leads to torment and excessive consumption of materials during sanding.

And this is just a filler primer! What can we say about paints and varnishes? Gloss, shade, texture and adhesion again... All this directly depends on viscosity.

Someone will ask: “What if you dilute it thinner so that it flows everywhere, adheres well and spreads smoothly, and apply it thicker so that there is room for sanding?”

Not the best solution, to put it mildly. A thick layer of liquid material contains a large amount of solvent - the coating will remain soft for a very long time (until it dries completely, not hours or days, but weeks and months), and enamel applied over a wet primer can lead to wrinkling of the coating and poor adhesion between the paint and the primer . In addition, the likelihood of such unpleasant defects as “boiling” and many others increases.

So, it is imperative to be able to control viscosity. The question arises: how?

How to measure viscosity?

You can often see how viscosity is measured in the following way: a painter takes some long object (for example a screwdriver), dips it into a can of prepared paint and God knows, by the signs, determines whether the viscosity is optimal or whether it needs to be diluted more.

It is worth saying that if this method is good, it is only for professionals with very extensive work experience. Well, someone, and they, as they say, feel the paint and varnish material with their skin. But what should novice painters who don’t have much experience do?

From our school physics course, we know that viscosity is usually measured in pascal seconds (dynamic viscosity) or in square meters per second (kinematic viscosity). It is also known that methods for determining the true viscosity properties of liquids are quite complex, which means they are not suitable for use in repair shops. Therefore, such a concept as “conditional viscosity” was introduced into circulation.

"Pros" and "cons" of using paint

Like any product, this paint is endowed with positive properties, but also has negative aspects. The advantages include the following:

The negative side is the inadmissibility of covering a surface that has a layer of bitumen paint.

It takes only three hours for the layers to dry, which will significantly affect the repair work.

Filtering

The prepared paint and varnish material must be filtered before filling into the tank of the spray gun, as it may contain foreign inclusions that got there during the preparation process, clots, etc. Otherwise, it is impossible to guarantee a high-quality coating, because all this debris may ultimately end up on the surface being painted.

For filtration, it is convenient to use disposable paper funnels with a nylon filter insert (mesh size, usually 190 microns). I inserted the funnel directly into the tank, strained it - ready, you can paint!

We fill the paint tank only using a filter funnel.
