 Types of varnish in cans

Aerosol varnishes are a special kind of varnish blends that are simple and easy to use. Nevertheless, someone who first encounters the need to use such materials is very surprised to learn about the number of existing options for coloring compositions. Therefore, acquiring such materials, it is worth exploring in detail what types of varnish in cans exist and what their differences lie in.

Benefits

Spray paints, regardless of manufacturer, have several advantages.

  • These compounds do not require dilution and mixing, they are ready for use from the minute they are purchased.To work with cans will not need extra waste on additional tools: brushes or rollers. Lucky sprays are produced in small-sized balloons, which makes them a practical and mobile material.
  • Often aerosols in cans are a type of quick-drying facing product. Drying time is a few minutes. Due to this property, no smudges form on the surface to be treated.
  • Varnishes-sprays are intended for spraying on various surfaces, such as metal, a brick, a tree, plastic. They can cover both flat surfaces and hard-to-reach places, all kinds of protrusions and bends, for example, areas of the machine that need to be updated, but it is very difficult to reach them. A striking example is the ceramic two-component lacquer "CERAMIC", which gives the surface a noble shine, protects the painted surface and increases its durability.
  • Lacquer mixtures in cylinders are very easy to operate. In order to use them, certain skills, experience and special conditions for work are not required - it is enough to get acquainted with the instructions for use indicated on the cylinder.The expense of means will be minimum - this type of putting facing material is considered the most economical. The coating layer will be uniform and uniform.
  • These coatings have a reasonable price, although they are more expensive than conventional paints.

Any varnish spray has excellent physical and chemical characteristics, is highly resistant to moisture and various aggressive substances, as well as resistance to temperature changes. The surface painted by these means is considered completely protected from various types of mechanical and atmospheric influences.

Species

There are several varnishes. Of these, two types of water-based should be distinguished: acrylic and polyurethane. The advantage of these sprays is their fire safety. In addition, they dry quickly enough, create a durable coating, practically do not have a specific caustic chemical smell, unlike paint.

Polyurethane

Polyurethane varnish is a derivative of polyesters and diisocyanates. This coating is resistant to physical stress. It is divided into two types: one-component and two-component (in aerosols onlyone-component compositions). May be water based or alcohol based.

Advantages of polyurethane varnishes:

  • due to its composition does not form cracks after complete drying;
  • do not exfoliate;
  • create a durable coating;
  • resistant to aggressive media and UV rays.

Acrylic

Acrylic lacquer is a viscous, water-soluble, almost odorless liquid. It is made of liquid polymer or the so-called acrylic dispersion.

This coating has the following physico-chemical properties:

  • drying occurs due to evaporation of water, after which the coating forms a film capable of protecting it from various mechanical damages;
  • after drying, the coating is not affected by any kind of liquid;
  • acrylic film maintains transparency and does not yellow under the influence of UV rays;
  • applied to any surface, including brick and concrete;
  • possesses high adhesion with well cleaned surfaces.

Nitrocellulose

Nitrocellulose lacquer is a compound of resins, colloxylin based on organic solvent. Has a pungent smell, after drying it becomes safe for health.Can be used inside the dwelling - provided that the ventilation is thorough. The drying period is one hour. Aerosol creates a durable coating with excellent protective characteristics, has excellent decorative qualities.

Based on the external characteristics, varnishes can be colored or transparent, matte or glossy. There is also a reflective aerosol, which discard particles of light from glossy surfaces. Which product to choose for work is the business of each customer. It all depends on the place of application, the type of painted surface and the expected results.

Application area

Regardless of the manufacturer, on the composition of the aerosol varnish, these sprays have a very extensive scope.

Conventionally, there are three main areas of use of varnish-spray.

  • Automotive industry. The composition is most often applied to matte paints on plastic and chrome.
  • At home. You can cover various pieces of furniture, accessories, accessories, toys with a universal composition, add shine to various surfaces, thereby creating works of art.
  • Construction Sphere. Widely used for coating various surfaces.

Application features

Apply varnishes in cans can not having a certain experience with them.

It is enough to follow a few simple recommendations.

  • Before using the can, shake well for 2-3 minutes. Its internal contents can be sprayed onto the surface if the sound of the ball is clearly heard inside the cartridge.
  • Before you begin to cover the surface, varnish should be sprayed in an inconspicuous place for the sample. If the painted surface has a black outer layer, then do not worry: the appearance of the product after spraying means will not suffer.
  • Spray onto the surface of the aerosol should be from a distance of about 30 cm, the canister should be held vertically.
  • Apply the aerosol chemical should be a uniform layer. If necessary, you can apply a second layer of coating, but only after a 10 minute pause.
  • If a small amount of varnish is needed to cover the surface and the entire contents of the cartridge has not been used, the residue can be left for the next time. However, it is necessary to clean the sprayer.To do this, turn the spray down and spray until the jet disappears.

Before painting begins, you should study the instructions and subsequently strictly adhere to the basic safety rules:

  • when using organic varnishes, ventilation is mandatory;
  • spray can not be sprayed near open flame;
  • It is necessary to have overalls, a mask for respiratory protection, goggles, gloves.

Water-based aerosol formulations do not require such strict safety procedures - in this case, the use of a mask and goggles can be excluded.

After completing the work, you must wait until the surface is completely dry. At the same time, it is necessary to take care that during drying it does not get dust, and try to protect it as much as possible from possible mechanical damage.
