Details

Device

Lacquer cans are made with a concave bottom, which protects the bottle from high pressure. Inside the tube, through which the paintwork material flows upward, the paint itself and an inert gas.

At the outlet of the tube there is a spray head and a valve, due to which the agent cannot be poured out without pressing.

Aerosol varnish already contains a solvent in its composition, therefore, spraying occurs in small drops. It can be applied in several even layers to achieve the best possible application.

Types

There are aerosol packages for hard and soft varnishes. Solids tend to have little fluidity.

Coating with such varnish should be done in two layers. It is considered the most environmentally friendly option due to its low solvent content. Soft ones are applied in three layers due to their fluid structure.

Another varnish is subdivided into depending on composition :

• Polyurethane. It is used for metal, wooden structures, as well as for protecting plastic products from mechanical stress.

  It is based on water, diisocyanate, polyesters, polyurethane, thanks to which reliable resistance to chemicals is provided. As a rule, this varnish has a one-component structure, but two-component ones are also available, consisting of a base and a hardener, which will need to be mixed before use.

• Acrylics are among the most harmless. They are also called furniture. The main component here is acrylic resin.

  After applying it, the natural look of the tree takes on the most striking appearance. Wooden furniture items become more resistant to UV radiation and do not yellow. It contains water, due to the evaporation of which it dries quickly. After application, it forms a film that adheres well to almost any material. However, it is better not to use acrylic varnish for very humid rooms, it is afraid of moisture.

• Nitrocellulose is composed of an organic mixture, resin and colloxylin. It is also water-based. This spray varnish is most often used for interior work in residential buildings. Quick drying (in 1 hour) and environmentally friendly.

Colored and transparent aerosol varnishes

Transparent are considered popular in the manufacture of furniture and car repair works.

They do not require auxiliary tinting, do not hide or tint the color of the wood. Such a varnish is simply irreplaceable for car headlights, car rim coatings, as well as expensive wood species.

Colored are more often used to cover inexpensive varieties of wood. With their help, they try to make paints brighter, as well as protect the surface. The most commonly used shades of beige, white and black.

The color is matched to a certain type of wood.

Pros

This kind of composition does not need additional dilution or mixing , it is immediately ready to use. No tools are required to use them. Such varnish is mobile and practical, since it is produced in small cans.

Fast drying, generally. Leave no smudges when applied. Can be applied to brick, wood, metal and plastic surfaces.

This varnish can be used to cover not only ideal surfaces, but also hard-to-reach places where it is impossible to reach with a brush, and even more so with a roller.

Ease of use is another advantage.

You don't need to have any special skills to spray paint from a spray can. Even a child can handle it.

Also, this is the most economical way of painting, because the consumption is minimal. The characteristics from the physical and chemical side are excellent: moisture resistant, resistance to chemicals, resistance to temperature fluctuations, etc.

There are almost no drawbacks here, just that you need to adhere to the requirements for the layer thickness.

Otherwise, it affects the quality of the coating.

Another disadvantage is that the surface needs protection before it dries completely. Particles of dust and debris can stick to a low surface.

Aerosol varnish is a topcoat used in many industries. And the quality of the coated surface will depend on how correctly it is applied.
