Selection and use of acrylic paint

Aerosol selection rules

The selection of the squad should be based on several factors:

• Scope of use. It can be universal, with a specific scope or specialized formulations. The latter option includes solutions that are suitable exclusively for painting metal, wood, leather or glass decoration.
• Manufacturer. It is better to choose proven brands that are sold in specialized stores.

  A well-known brand in many ways guarantees the high quality of dyes

• Consumption. This indicator depends on the volume of the cylinder and is indicated by each manufacturer individually, but the average value for a standard container is 3–3.5 m2. To calculate the required amount of material, the wall area of ​​the painted area or product is measured. The number of layers is also taken into account, there must be at least two of them.
• Price. Spray paint can't be cheap. This is especially true for special varieties.

When choosing, you must carefully inspect the cylinder. If there are any defects, the specific product should be discarded.

Advantages and disadvantages of aerosols

Structurally, the can is very simple. The container is filled with gas and paint, which are under pressure there. The function of the gas is to maintain equilibrium among the components of the content.

Advantages of spray paints:

1. The paint is always ready for use. Before painting, you just need to shake the can.
2. Aerosol formulations are the best choice when it comes to painting small parts or hard-to-reach areas, as the sprayed particles will enter even subtle depressions.
3. During work, you can completely do without additional tools (brushes, rollers).
4. Spray paint has the same performance characteristics as the compositions in cans: adhesion level, elasticity, resistance to abrasion, moisture and ultraviolet light.
5. Aerosol mixtures dry very quickly (5-6 hours).
6. The cans are easy to store and transport. The paint in such containers practically does not dry out during storage. In addition, the cans are more airtight than other types of packaging, which eliminates specific paint and varnish odors.
7. Available in a wide variety of colors.
8. There are paints with special effects, including hammer, pearlescent, fluorescent, metallic, textured. With this composition, you can give the surface a glossy, semi-gloss or matte appearance.
9. Thanks to spraying, the color rendering from one color to another is especially smooth.

Disadvantages of aerosols:

Painting technology

To obtain a high-quality result when applying paint with a spray can, you need to adhere to certain rules:

1. To avoid poisoning with the contents, you must use protection, namely a respirator, goggles or mask.
2. Before applying paint, the surface should be prepared: remove dust, dirt, and degrease with White Spirit. It is also necessary to apply a primer to the surface (preferably a special aerosol, although you can use a regular one). To ensure the highest quality, it is recommended to use a primer and spray paint from the same manufacturer.
3. Nearby surfaces must be protected from accidental paint splashes. For this, masking tape is suitable. In addition, it is advisable to have a rag on hand, which, if necessary, can remove unwanted traces of still fresh paint.
4. In order for the paint and varnish material to acquire a uniform consistency, the container must be shaken well several times.First, it is recommended to make a test stain on a test surface - this will allow you to evaluate the uniformity of the composition.
5. When painting, hold the spray can with the nozzle towards the surface to be painted at a distance of about 25 centimeters. The paint is sprayed in such a way that the pigment falls on the surface in 2-3 layers. However, the layers should not be excessively thick, as excess paint can cause sagging.
6. Spray painting should be carried out only in calm, not cloudy weather.
7. The surface to be painted should ideally be horizontal. If we are talking about a vertical surface (for example, a wall), then painting is carried out from top to bottom, so in this case the risk of drips is reduced.
8. After applying the first layer, you need to wait for the initial drying of the paint. The approximate waiting time is 30 minutes. When the coating “grasps”, you can start applying the next layer.
9. Complete drying of the paint occurs in 5-6 hours. However, in some cases, drying must be waited for several days.
10. If necessary to fix the painted surface, you can use acrylic varnish.

Automotive paints and their features

For painting plastic with your own hands, you can also use specialized car paints and primers.

Base for varnish. This type of enamel must be applied to a special primer for plastic, which will increase its adhesion to the surface of the part. Finally, the area to be painted must be covered with an aerosol varnish. The base enamel comes in simple colors, as well as with metallic and mother-of-pearl effects, which allows you to transform interior items.

Along with the base for varnish, paints with various effects are made for gold, platinum, antique silver or copper. They have the finest grind of the dye, due to which a reliable imitation of the precious metal is created.

• Vinyl paints. If you are a fan of interior decoration under the skin, then this paint is your option. Any plastic surface painted with vinyl enamel will look and feel as similar as possible to leather products. The advantage of this paint is plasticity and an increased level of adhesion, which makes it possible to exclude a primer. You can not be afraid of cracks and chips, this is excluded.
• High temperature enamels. Of course, interior items can hardly be heated to temperatures that this enamel can withstand. But if you want to repaint or update the surface of an electric kettle, vacuum cleaner, plastic parts of a coffee machine that heat up in one way or another, then high-temperature paints will come to your aid.

Before painting parts, you must:

• clean the plastic surface with sandpaper with an abrasiveness of the order of 1500-200 grit;
• degrease the site of the intended application of the enamel with an alcohol cleaner using a lint-free cloth;
• before painting the main part, you should practice on an unnecessary piece of plastic: determine the pressure on the spray head and choose the optimal distance from the can to the surface.

You will learn how to paint the plastic yourself with a spray can in the following video.

How to properly store varnish spray in a can?

Storage recommendations are provided on the label affixed to the spray wood varnish.

So, all cylinders sold on the market are stored at ambient temperature in summer, and in winter these indicators can drop to -20 ° C, which already exceeds all permissible standards. Therefore, such material, even if it is just produced, deteriorates after 1-2 weeks, losing its quality.

Using an expired or deteriorated varnish, you run the risk of spoiling the treated wood surface, which, as a result of exposure to such varnish, will become covered with bubbles, stains or wrinkle.

Now you can find out which varnish in an aerosol can for wood is better to buy, and how not to be mistaken with the choice. These tips and instructions will help you choose the right paintwork option to give furniture or other surfaces, regardless of the number of stains, a fresh new look.

Wood paint in aerosol cans is presented in a wide range. Aerosol paints, in addition to the reliability of the coating, provide an even thin layer, which is very difficult to achieve when treating the surface with ordinary paint with a brush or roller.

Pros and cons of using paintwork in the form of sprays

The benefits of using spray paints include:

• absolute readiness of the paint for application (there is no need for special preparation of the composition, it is enough to shake the can thoroughly to achieve the correct consistency);
• there is no need to purchase additional painting supplies (trays, brushes, solvents);
• high adhesion (the paint adheres well to the surface, without the formation of streaks and smears);
• the possibility of processing small parts (by spraying the composition, the paint penetrates into the smallest patterns, without leaving unpainted areas);
• the ability to create decorative effects (patina, metallic, matte or glossy surface, mother of pearl, crackle, fluorescent coating).

Among the disadvantages of aerosols when processing wood, the following can be distinguished:

1. The inability to independently create the desired shade by mixing paints and tinting. Although this disadvantage is compensated for by a wide range of color palettes, including various halftones.
2. If the application technique is not followed, streaks or streaks may form. However, improper staining can lead to similar problems with conventional canned colors.
3. The need to use stencils to create a clear border of staining. This drawback is also controversial, because when using cans, masking tape is also used to create even processing boundaries.

Aerosol paints for wood allow you to process products of any shape. You can use coloring sprays:

• when carrying out repairs for processing large surfaces;
• for the restoration of old products (for example, renewing old wooden furniture or window frames);
• for decoration (for example, apply an image through a stencil or simply treat the surface with a decorative coating).

Aerosols have won recognition and popularity among consumers due to their unique properties and undeniable benefits.

Which spray is better: clear or colored?

Clear varnish is used most often. It's all about its versatility. It is almost invisible on the surface of the tree and does not hide the natural pattern of the tree species.

This is the best finish for expensive woods such as oak, mahogany or beech.

For cheaper types of wood, colored aerosols are predominantly used. Using a colored spray can easily hide some surface problems and not just protect it. In addition, it will help create an expensive, noble look of furniture made from simple lumber.

A wide palette of colors allows you to choose any shade that suits the style of the interior. When buying an aerosol, consider:

• The absorption property of the spray varnish. For example, water-dispersion compositions do not penetrate so deeply.
• Gloss level. The stronger it is, the more pronounced the surface looks.

Advantages and disadvantages

The advantages of this material include:

• Readiness. The product is always ready to use. The paint does not need to be diluted, prepared, poured into a special tray and other similar work. All that needs to be done before work: shake the container a couple of times and start staining.
• Shipping.The paint can be transported in both large and small batches, without fear for the contents of the spray cans. A special device will not allow the substance to leak out. The container is absolutely airtight, not allowing even the persistent and strong smell characteristic of paint to pass through.
• Convenience. The paint does not take up much space. It can be placed even in the smallest pantry. During operation, the balloon is comfortable to hold in the hand. The elongated shape is practical and ergonomic. The material does not dry out during storage.
• Simple to use. No additional tools or equipment needed. One spray can replace the paint can, brush and roller. This significantly saves material costs for repairs and the time of its implementation.
• Drying speed. The composition dries very quickly. The maximum time is 5 to 6 hours.

Range

The huge range of colors attracts the attention of both ordinary buyers and professional designers. In product catalogs you can find metallic colors (bronze, gold, silver), classic and pastel shades, bright colors, chrome and other options

Not only the color of the composition differs, but also its texture after drying.

Thorough painting. The substance in the spray can help paint over hard-to-reach places that cannot be reached with a roller or brush. In addition, the paint will lay evenly and neatly. Fine spray will reach any small and invisible elements.

Price. The price for quality products is quite affordable. The average consumer has the ability to buy several cans at a time. This is enough to paint a standard room.

Originality. In the shops of finishing materials you will find products for unusual decoration. Connoisseurs of original decor will love pearlescent, fluorescent, shiny and other amazing colors.

Versatility. This type of paint can be used in different rooms of a residential building (bathroom, kitchen, bedroom, hallway and other rooms). This paint is also used by artists who paint in various techniques.

Aesthetics. Due to the uniform application of paint, the finished coating retains its attractive appearance for many years.

To the above properties, you can add several more advantages of paint: reliability, practicality, wear resistance, durability, resistance to moisture, frost, temperature and much more.

These characteristics may vary, depending on the components in the composition, additional ingredients and the manufacturer.

Each product has a reverse side of the coin and acrylic paint in cylinders is no exception. Let's get acquainted with the disadvantages in order to fully appreciate the products of this type:

• Combining several colors, creating a special shade, will not work.
• To perfectly paint the surface with a spray, you will have to adapt. Otherwise, smudges may remain.
• If you want to create an original drawing, you can't do with a stencil. For standard painting of walls, floors or ceilings, you will need masking tape. This will help create a crisp, clean edge.
• It will not work to change the thickness of the paint.
• It is possible to use spray paint in open areas only in calm weather, otherwise the paint will be sprayed in all directions, without reaching the required surface.

Varieties of aerosols

The whole variety of aerosol enamels can be divided into 3 groups:

• acrylic;
• alkyd;
• nitroenamel.

An aerosol of acrylic-based paints is used to cover elements of external decoration, interior details. They are popular, albeit not cheap. Such paints:

1. dry quickly;
2. have a high level of adhesion (adhesion to the surface);
3. have a rich palette of shades;
4. easy to apply;
5. provide the relative durability of staining, do not fade;
6. low toxic.

In alkyd compositions there are advantages similar to acrylic paints, but the resins present in them give them a certain level of toxicity, so you need to use a respirator and other protective equipment (mask, goggles). The service life is shorter than that of acrylic, the degree of adhesion is lower due to the presence of oil components.

For nitrocellulose enamels, where cellulose nitrate is present, a high level of toxicity is characteristic, therefore they are not so popular. But they dry quickly, and the competent application of such enamel provides a durable coating, while the nitro enamel aerosol is relatively inexpensive.

Aerosol enamels for metal

Used for painting facade elements and for interior work. Eco-enamels are characterized by a vanilla smell. The standard version of the enamel gives a shade, double - combined with a primer, triple - supplemented with a rust converter. These aerosols are used for cast iron or steel products.

Construction and heat-resistant enamels

Variants of aerosols with heat-resistant properties are used to cover surfaces operating at high temperatures (boiler, stove, fireplace, heating devices). In construction, they cover wood, concrete surfaces, ceramics, walls in apartments, they are used for surfaces that function at high humidity (walls of pools, saunas).

Compositions for painting plastic and wood

Enamel for plastic in aerosols is used everywhere, including for painting scratches and defects on car surfaces. It has a high level of adhesion, there are options with abrasion resistance, a structural effect that allows you to smooth out the unevenness of the plastic. This is handy for plastic that needs to be refurbished. Compositions for painting plastic: polymer, with PVC mixtures, polyurethane resins.

Decorative compositions

It is convenient to decorate glass, household items, apply stencils with aerosol paint of a special type of RAL. Water-based enamels are used to decorate textiles (curtains, roller blinds).

How to properly work with a dye bottle

When sprayed, paints in aerosol cans form a fine suspension in the air, which settles not only on the object to be painted, but on other surfaces. In addition, small particles of paint can enter the eyes or the respiratory tract. To avoid this, you need to do the following:

1. Covering material (for this purpose, you can use plastic wrap, cardboard, old fabric, etc.) to cover all areas not intended for staining. Narrow places that do not need to be painted should be sealed with masking tape.
2. Wear protective goggles, respirator and gloves while working.

After this preparation, you can paint. This should be done as follows:

1. If the thing to be painted is small, then in order to improve the quality of the painting, it is better to place it on a horizontal surface covered with a covering material.
2. Shake the enamel can for 30-40 seconds to mix the dye.
3. Remove the cap and release the first test stream of paint onto an unnecessary base, for example, a piece of cardboard. This is necessary because air can accumulate in the sprayer, and the first pieces of enamel will fly out in uneven "spits". After the dye begins to come out of the container evenly, you can start painting the plastic.
4. When spraying, move the hand with the aerosol with smooth movements, without lingering in one place. Long-term spraying of one area leads to the formation of enamel drips. Keep the aerosol at a distance of 20-30 cm from the surface to be painted.
5. After staining, let the first coat dry (about 20-30 minutes) and paint again. Apply third and subsequent coats if necessary.

Despite the fact that the coloring solutions for plastics dry out quickly, it is recommended to start using the product only after a day.During this time, the final polymerization of the coloring agent will occur, and the decorative layer will become durable.

Nozzles

The application of paint and varnish material to the surface is carried out using a special device - a nozzle. You can buy a nozzle separately from the spray.

Spray paint nozzles are inexpensive, so they can be purchased in several types at once:

1. The fine nozzle allows the surface to be painted with a fine jet. Designed for fine detail. With the help of a fine nozzle, lines are applied with a thickness ranging from 0.8 to 4 centimeters.
2. Medium nozzles are used to apply stripes up to 5 centimeters wide.
3. Thanks to the wide nozzles, strips that are 10 cm wide can be output.

Advice! The nozzle must be selected so that the pressure level in the can does not exceed the allowable pressure for this part. The fact is that different manufacturers of paint in cylinders set different pressure levels. This indicator is not critical, however, it has some influence on the final result of the work.

Color palette

Spray paints come in a wide variety of colors. Black, gold or, for example, bright green paint look equally impressive on a metal surface. The palette is presented in a wide variety of shades: from delicate pastel tones to bright and dark with various effects.

The most popular paint with the "metallic" effect, which gives the surface a durable metallic shine and provides reliable protection against any external factors.

In addition, you can find in stores with effects:

• chameleon;
• rainbow;
• pearlescent;
• reflective;
• luminescent and others.
