Paint for metal in spray cans nuances of using aerosols

Advantages and disadvantages of aerosols

There are no specific difficulties in the design of an aerosol can. The paint is pumped inward under pressure in combination with a chemical gas to maintain equilibrium between the components of the content. The advantages of using aerosol enamel are undeniable, but there are also disadvantages.

The obvious advantages of aerosol enamels include:

1. Lack of preparation for painting, light shaking of the can is enough.
2. The ability to paint areas with a complex configuration, with inconvenient shallow depressions or protrusions.
3. No need for brushes, rollers, containers.
4. Aerosol paint has the same performance characteristics as paint produced in various containers: its level of adhesion and elasticity meets all the requirements, it is resistant to abrasion, sunlight, and moisture resistant.
5. Short drying time of the paint.
6. Convenience of storage and transportation of cans.
7. The tightness of the packaging not only protects the paint from drying out, but also prevents the appearance of odors.
8. The palette of shades satisfies the most demanding taste.
9. The aerosol does an excellent job of updating cast iron and steel surfaces.

The list of disadvantages:

• Not being able to mix colors from a spray can.
• You cannot change the thickness of the material with a solvent.
• It is necessary to preliminarily delimit the area to be painted with masking tape or other means in order to protect them from enamel ingress as a result of spraying.
• The aerosol is inconvenient to use for outdoor work if the weather is windy.
• The relative fragility of painting, since when sprayed with an aerosol, the surface is covered with a thin layer.
• Without certain skills, it is difficult to achieve uniform coloring and avoid smudges and ugly streaks.

Aerosol tips

A suitable spray paint must be selected taking into account several recommendations:

The total amount of paint in the aerosol must be calculated in advance, paying attention to the spray rate indicated on the can, taking into account double or triple application of paint.
The required shade is selected from the catalog (RAL, NCS).
The choice of the type of enamel in aerosol design depends on the material of the surface to be painted. Plastic, glass, wood is well painted with acrylic enamels

Metal is preferably painted with zinc spray paint with an aluminum additive. For ceramics or enameled surfaces, an aerosol is suitable, the basis of which is an epoxy resin with the addition of pigments and fillers.
If the goal is not so much painting itself, but giving the surface a "new look", you need to opt for enamel, which allows you to achieve various visual effects (fluorescent glow, display of any texture).

Types of colorful aerosols and tips for choosing

The range of aerosol paints is very wide: from universal to specialized, as well as creating special decorative effects.

Universal

Among the most popular are universal alkyd-based decorative enamels and acrylic enamels. They are suitable for both outdoor and indoor use. The finished coating protects the painted surfaces from weathering for a long time, and, in addition, has a high resistance to impacts, bends and other mechanical influences. The manufacturer tints the enamels (matte, glossy, with a metallic effect) in accordance with the European RAL color standard. They are applied to a previously prepared and primed base.

If you spray water in the room before painting, dust particles and other airborne debris will not settle and remain on the painted surface. To avoid clogging of the spray head, after work, the cylinder is turned upside down and the composition is sprayed until a clean propellant gas starts to come out.

"Spectrum"

When choosing a heat-resistant spray paint, pay attention to the operating temperature range of the coating and the anti-corrosion properties of the composition, which are especially important for metal products operated in high humidity conditions.

Heat resistant

Heat-resistant aerosol compositions are intended for painting heating metal surfaces: elements of exhaust systems of cars, pipelines and steam lines, various parts of water-heating and boiler equipment, fireplaces and stoves, barbecues. The thermal resistance of the protective and decorative film starts from 80 ° С, as in Alkyd enamel for radiators (Kudo), and reaches extreme 1000 ° С, as in matte Certa enamel (Spectrum) for barbecues, stoves, fireplaces and metal structures.

With an unusual effect

Among aerosols with unusual effects, we note luminous ones: phosphorescent and fluorescent. The former absorb the light energy of ultraviolet rays, incandescent lamps and then slowly release it, which is manifested by a glow in the dark. Moreover, it resumes an unlimited number of times after repeated exposure to the light source. Such paints are useful for decorating Christmas tree decorations, toys, watches, etc. Fluorescent aerosols are highly reflective. When exposed to sunlight or ultraviolet rays, their brightness increases many times. And this is often used by designers when decorating interiors and exteriors.

Spray paints with craquelure effect will give a touch of noble antiquity to furniture items, architectural decor. It is obtained by successively applying two coats. The base is applied first, which will subsequently be visible in the cracks, and after it dries, the finishing one. A network of small cracks appears on its uniformly thin layer. To form larger craquelures, without waiting for the first finishing layer to dry, apply a few more (one or three).

Among the unusual decorative effects that aerosol paints can create, there are many others. This is, for example, an imitation of an aged metal surface, with natural oxides, as well as the chameleon effect, when the coating changes color depending on the angle of incidence of light (it is especially pronounced on objects with smooth bends), or the effect of frost, which is very useful on New Year's Eve. of the year.

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.

Features of use

Painting metal surfaces with aerosol paints is a fairly simple procedure that is easy to perform, knowing all the features of the work:

• Prepare the surface before applying the coloring agent. It is enough just to remove dust and dirt from the metal and wipe it with a product that removes excess grease. One of the most common products is white spirit, which does not harm surfaces.
• When the metal is cleaned, the surface must be primed. This can be done in a number of ways. The easiest one is to buy a special paint, which is not only pigmented, but also contains a primer.

When working, it is very important to protect all those surfaces that need to remain clean with simple masking tape. It peels off easily and leaves no residue behind
Of the safety equipment, it is also worth preparing a rag soaked in a special solution. It will help to remove all unnecessary and get rid of drips.

Although they are practically non-existent when working with a spray, do not forget about these simple precautions that will help you do everything neatly.
When all the preparatory work is completed, you can proceed to painting. In order for the color to fit well, you need to shake the can

This will dissolve the pigment, and the shade will be applied to the surface in an even layer.

After the paint is mixed, you can test it. It is advisable to do this not on the surface, which will be painted, so as not to get bald spots and ugly spots.

If everything suits you and the paint is sprayed well, then you can start the main work.
When applying paint, it is important to ensure that the distance from the spray gun to the surface to be painted is not too close. As a rule, the best option is chosen - from twenty to thirty centimeters

It is imperative to spray the product with confident and quick movements. So the color will lie in an even layer.

If a car or something else located on the street is painted, it is important to remember that the work should be carried out in calm weather so that there are no drips.
As a rule, one coat of paint is not enough, so several passes have to be done. Each new one should be applied only after the previous one is completely dry.

If desired, you can fix the finishing layer with varnish so that the paint lasts longer. The painted metal will completely dry in about six hours.But if possible, it is better to wait a little longer - at least a day.

Positive and negative properties of aerosol colorants

A paint bottle, like any other product, has both positive and negative sides. To decide whether to choose them as a means for coloring an object, you need to study these sides in detail. The advantages of aerosol paints include the following properties:

• Ready-made form, it is not required to stir and dilute with other elements, it is enough just to shake the container;
• The spray method allows you to paint hard-to-reach places and the smallest parts without difficulty, they will provide high-quality painting of all elements;
• No need to purchase additional tools;
• The performance characteristics of this type of paint and varnish material are not inferior in quality to other types;
• Fast drying property;
• Convenience of transportation and storage. They do not take up much space, and the spray can allows the paint not to dry for a long time, and they can be used for a long time after opening the package, the tightness of the aerosol closure eliminates the spread of the paint smell outward;
• Variety of color palette;
• A variety of effects obtained, which makes it possible to implement various ideas of the designer;
• The spray method makes it possible to create a smooth transition from one shade to another.

The spray method allows you to paint hard-to-reach areas and the smallest parts with ease.

The tool also has disadvantages:

• You cannot mix different colors with each other to obtain a separate shade;
• The need to possess certain skills in order to get coatings without drips, beginners should practice;
• To create a transition border, it is worth using stencils, or create a separation using masking tape;
• There is no possibility of creating a less thick consistency by adding a thinner;
• When working outdoors, the weather should be calm, otherwise the product will stain other nearby objects as well.

When working outdoors, the weather should be calm.

Types of colorful aerosols

Paint and varnish cans are not the same, they are of several types. There are only three main groups of paints: alkyd, acrylic, nitro enamels. It is advisable to choose the type based on the task.

Spray acrylic paint is used for interior and exterior decoration of various structures. They are highly demanded. The following advantages of this type can be distinguished:

• Dry quickly;
• High degree of adhesion;
• Variety of colors;
• Ease of use;
• The coating lasts a long time, withstand exposure to ultraviolet radiation;
• Low level of toxicity.

Spray acrylic paint is used for interior and exterior decoration of various structures.

Alkyd paints help to achieve similar characteristics to acrylic-based paints. However, their constituents are more toxic, which requires compliance with safety measures. In addition, the service life is shorter, the degree of adhesion is less. However, they also cost less, which makes them popular as well.

Their constituent elements are more toxic, which requires compliance with safety measures.

Nitro enamels are distinguished by a high level of toxicity, therefore they are chosen less often. Their price is lower, and if applied correctly, the coating will serve for a long time, it dries quickly.

When applied correctly, the coating will serve for a long time, dries quickly.

Aerosol enamels for metal

They can be used for work inside and outside the building. Eco-enamels have a vanilla aroma. Can be used to coat steel and cast iron metals. Regular enamel serves to change the color, there are enamels that can be applied together with the primer mixture. They also produce products with an anti-corrosion effect.

Can be used to coat steel and cast iron metals.

Construction and heat-resistant enamels

Produce special enamels in cans that can withstand high temperature exposure. They can safely paint stoves, radiators, fireplaces. In construction, they are used to cover concrete substrates, indoor walls, and ceramic surfaces. For surfaces that are constantly exposed to moisture (swimming pools, saunas).

Compositions for painting plastic and wood

To correct defects that appear on a plastic surface, it is often aerosol paints that are chosen.

They are distinguished by a high level of adhesion, which is important when working with plastics. May have additional properties in the form of resistance to abrasive substances, a structural effect that allows the plastic coating to be leveled

Most often chosen to update the appearance of old items. It is important for the tree to create additional protection against moisture.

Spray paints are often chosen to correct defects on plastic surfaces.

Decorative compositions

Manufacturers have come up with a separate type of coating, denoted by the abbreviation RAL. They are designed to cover glass objects with ease. Work in a domestic environment and apply stencils to various materials. The water-based composition is safe and can be used for dyeing textiles.

They are designed to cover glass objects with ease.

What is spray paint

Spray paint is a mixture of paint and propellant stored in a hermetically sealed aerosol. To start surface treatment, you must press a special button, and the mixture will be sprayed on the object. This application technique allows you to obtain a uniform distribution of the composition over the surface, to create a thin and beautiful layer. The process takes less time than using a brush or roller.

The presence of the propellant allows you to create the required pressure, its quantitative content can vary from 20% to 60% of the entire composition of the cartridge. The pressure level depends on temperature indicators, the higher it is, the higher the pressure, and vice versa.

An aerosol can with paint should be matched to the material to be processed; at the moment, a large number of specialized compounds are produced for metal, plastic, wood, glass, concrete and others.

The volume of aerosols is usually small in order to be conveniently transported and used. Average consumption may vary slightly depending on the brand of the product, usually it is 1-2 m2. Note the long shelf life of the paint after opening the spray can.

This application technique allows you to obtain a uniform distribution of the composition over the surface, to create a thin and beautiful layer.

How to choose?

Aerosol paints that are used to paint metal are presented in several versions:

Standard paints are simple sprays that are used for general surface painting. With their help, you can achieve the desired color. High-quality pigments adhere well to the surface and one layer, as a rule, is enough to achieve the desired shade.
The next example of paints is of the dual type. They are used not only to achieve the desired color, but also to prime the surface.
The last option is triple-type paints. Among other things, they also protect the surface from corrosion.

This is very important as rust often forms on metal substrates.

It is worth choosing a paint, focusing on the conditions in which it will be used. So, for example, for surface treatment outside the house, it is worth choosing the third option. True, here you also have to take into account the cost of the product, since high-quality paint always costs more.

The colors also differ. As already mentioned, the color palette of aerosol paints is richer than usual. That is why they are often used for decoration.

The colors are both matte and glossy. Shades such as bronze, matte black or iridescent, which are rarely found among paints in cans, for example, look beautiful.

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.

Note! Aerosol formulations are fire hazardous and should be kept away from open flames. This rule applies to both storage and spraying.
