Aerosol varnishes are a special type of varnish mixtures that is simple and easy to use. Nevertheless, whoever first encounters the need to use such materials is very surprised to learn about the number of existing options for coloring compounds. Therefore, acquiring such materials, it is worthwhile to familiarize yourself in detail what types of varnish in the cans exist and what their differences lie in.
Benefits
Aerosol varnishes, regardless of manufacturer, have several advantages.
- These compositions do not require dilution and mixing, they are ready for use from the moment of their acquisition. To work with spray cans, you will not need extra waste on additional tools: brushes or rollers. Spray varnishes are available in small-volume cylinders, which makes them practical and mobile material.
- Aerosols in spray cans are often a type of quick-drying coating product. Drying time is several minutes. Due to this property, smudges do not form on the treated surface.
- Spray varnishes are designed for spraying on various surfaces, such as metal, brick, wood, plastic. They can cover both flat surfaces and inaccessible places, all kinds of protrusions and bends, for example, sections of the machine that need to be updated, but it is very difficult to reach them. A striking example is the ceramic two-component varnish “CERAMIC”, which gives the surface a noble shine, protects the painted surface and increases its wear resistance.
- Varnish mixtures in cylinders are very easy to operate. In order to use them, certain skills, experience and special working conditions are not required - just read the instructions for use indicated on the cylinder. The expense of funds will be minimal - this type of coating material is considered the most economical. The coating layer will be uniform and uniform.
- These coatings have an affordable price, although they are more expensive than conventional paints and varnishes.
Any varnish spray has excellent physicochemical characteristics, is highly resistant to moisture and various aggressive substances, as well as stability to temperature extremes. The surface painted by these means is considered completely protected from various types of mechanical and atmospheric influences.
Varieties
There are several varieties of varnishes. Of these, two types of water-based are worth highlighting: 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. Such a coating is resistant to physical influences. It is divided into two types: one-component and two-component (in aerosols only one-component compositions are used). May be water based or alcohol-based.
Advantages of polyurethane varnishes:
- due to its composition they do not form cracks after complete drying,
- do not exfoliate
- create a durable coating
- resistant to aggressive environments and UV rays.
Acrylic
Acrylic varnish is a viscous water-soluble liquid, almost odorless. It is made of liquid polymer or the so-called acrylic dispersion.
This coating has the following physicochemical properties:
- drying occurs due to the evaporation of water, after which the coating forms a film capable of protecting it from various mechanical damage,
- after drying, the coating is not influenced by any kind of liquid,
- acrylic film retains transparency and does not turn yellow under the influence of UV rays,
- can be applied to any surface, including brick and concrete,
- possesses high adhesion with well cleared surfaces.
Nitrocellulose
Nitrocellulose lacquer is a compound of resins, colloxylin based on an organic solvent. It has a pungent odor, after drying it becomes safe for health. It can be used inside the living room - subject to careful ventilation. The drying period is one hour. Aerosol creates a durable coating with excellent protective characteristics, has excellent decorative qualities.
Based on external characteristics, varnishes can be colored or transparent, matte or glossy. There is also a reflective aerosol that is discarded by particles of light from glossy surfaces. Which product to choose for the job is the business of every customer. It all depends on the place of application, the type of surface to be painted and the expected results.
Application area
Regardless of the manufacturer, the composition of the spray varnish, these sprays have a very wide scope.
Conventionally, there are three main areas of use of varnish-spray.
- Automotive industry. The composition is most often applied to matte paints in plastic and chrome.
- At home. The universal composition can cover various pieces of furniture, accessories, accessories, toys, give shine to various surfaces, thereby creating works of art.
- Construction industry. Widely used to cover various surfaces.
Application Features
Apply varnishes in spray cans without having a certain experience with them.
It is enough to follow a few simple recommendations.
- Shake well before use for 2-3 minutes. Its internal contents can be sprayed to the surface if the sound of a ball is clearly audible inside the can.
- Before starting to cover the surface, the varnish should be sprayed in an inconspicuous place for the sample. If the painted surface has a black outer layer, then you should not worry: the appearance of the product after spraying the product will not suffer.
- Spray to the surface with an aerosol from a distance of about 30 cm, the spray can must be kept upright.
- Apply the aerosol chemical in a uniform layer. If necessary, you can re-apply the 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 spray can not be used, then the remainder can be left the next time. However, the spray gun must be cleaned. To do this, turn the can down and spray until the jet disappears.
Before starting the painting, you should study the instructions and then strictly adhere to the basic safety rules:
- when using organic varnishes, ventilation is mandatory,
- do not spray the can near open flames,
- it is necessary to have overalls, a mask for respiratory protection, goggles, gloves.
Water-based aerosol formulations do not require such strict safety precautions - in this case, the use of masks and glasses can be excluded.
After finishing work, you must wait until the surface is completely dry. At the same time, care must be taken to ensure that dust does not get on it during drying, and try to protect it as much as possible from possible mechanical damage.

Glossy or matte
Gloss is best suited for dark surfaces, as it allows you to get a spectacular shine. Use such material for furniture decoration.
This type of coating emphasizes the pattern and contrast of the lines. However, mechanical damage on a glossy surface will be more noticeable.
The strength of the processed material does not depend on whether a glossy or matte spray will be used. This parameter is affected by the manufacturing quality of the composition. The best properties are usually characterized by expensive models.
Matte spray can simplify the cleaning process, as it needs minimal maintenance. This varnish is used when it is necessary to achieve a natural coating of the paint.
Careful grinding of the product will make the final result more aesthetic.
Transparent or color
Transparent models are in greatest demand because they are universal. Thanks to this composition, you can consider the natural pattern of wood. You can use a similar varnish on different types of wood. It is better to use a transparent version on expensive species (for example, oak, beech). Colored aerosols are best used on cheap wood.
Such material allows you to solve several problems, he:
- improves the color of the paint,
- creates a noble expensive appearance,
- protects the surface from damage.
Today, you can purchase varnish in various shades. You can choose the composition for any interior. The most popular is the white and black color of paint in spray cans.
Using white, you can process parquet and light surfaces, black will create a touch of luxury.
When buying, you need to consider 2 parameters:
- Absorbency. Water-based coating is not characterized by deep penetration.
- Shine. The larger it is, the darker the surface will look.

A respirator and protective gloves should be used in the work area, as many varnishes contain toxic solvents. These tips will help to varnish with an excellent result and is safe for health.
How to store the composition
Not always a high price indicates the quality of products. Sometimes branded aerosols can actually be fakes. Such situations arise when purchases are made in markets and stalls. Also, aerosol varnish may not be suitable for use due to non-compliance with storage conditions.
The average shelf life of paint materials is about 2 years. However, in reality, it may be less if the aerosol was stored in an improper way.
All recommendations for storing the spray are on the label. Particular attention should be paid to the permissible temperature difference. This criterion can tell whether it is worth buying a product in a given place.
For example, on the market all bottles with varnishes are stored at ambient temperature. In winter, it can reach 20 degrees. At this temperature, the aerosol will become unusable in a few weeks, will lose the necessary qualities. When using it, clouding on surfaces is possible, and peeling of varnishing may occur soon.
Exposure to too high a temperature is also detrimental to varnishes in aerosol cans. If you store it in the summer in the open, the hardener will begin to thicken. This will lead to the absolute unsuitability of the product in a month.
Therefore, it is best to purchase paints and varnishes in specialized stores. The main criterion for choosing should be the conditions that are created for its storage. Of course, price and manufacturer also matter. Budget options will have lower paint quality.
Storage rules
Expensive mixtures are not always of high quality, there are cases when branded spray cans are faked, especially fakes are found in stalls and on the market. In addition, if storage conditions are not followed, then the varnish mixture will lose its characteristics, and may be unsuitable for use.
Attention! The average shelf life of varnish materials is approximately 2 years, but this period can be significantly reduced if the varnish was stored in the wrong conditions.
Conditions and recommendations for storage of the can are written in the instructions or on the label. The main criterion is the storage temperature of the spray for cars or for wood. Given the temperature, you can understand whether it is worth buying products in the market, in a stall or in a store. For example, cans are stored on the market at air temperature; in winter, the temperature sometimes drops to -20 degrees. This temperature adversely affects the mixture in the can, which will become unusable after a couple of weeks. If you apply such a varnish to the surface, then it may become cloudy, and very quickly begin to exfoliate from the base.
High temperatures also badly affect aerosol cans. If in the summer at a temperature of 30-35 degrees to keep the can in the open air, the mixture will thicken, which will lead to its unsuitability after one month. Therefore, it is much better to buy varnish products for cars in stores where the best conditions for storage are created.
Aerosol spray can
The concave bottom protects the cylinder from high pressure. Inside, there is paint (varnish) and inert gas, and a tube passes through which the paint comes up. It ends with a spray head with a valve, the latter does not allow the medium to exit before being pressed.
The varnish in aerosol form contains a sufficient amount of diluent (solvent), so it is sprayed with very small drops. But liquid varnish can be applied in several layers, which gives a better result.
Colored and transparent varnishes
Transparent varnish is the most popular in car repair and furniture production. It does not need to be additionally tinted, it will not change the color of the main coating and will not hide the natural beauty of the tree. Transparent varnishes are indispensable for coating rims, headlights, as well as expensive varieties of wood - oak, beech, mahogany.
Colored varnishes are often used for cheaper types of wood. They help:
- enhance the brightness of the paint,
- protect wood
- give the product a noble appearance.
Most often, shades are used for different types of wood, as well as white, beige and black. Light paintwork materials cover the parquet, laminate, furniture to improve the appearance, gloss. When buying a product, it is important to take into account the penetration depth and the degree of gloss (the surface will look darker from strong gloss).
Tinting varnishes for car bodies should have increased strength. Suitable for these purposes 2K glossy and a series of varnishes brand KUDO. There are specialized products in headlight spray sprays (for example, Lens Clear HB Body headlight spray varnish).
Of the colored matte varnishes, Auto Dip liquid rubber should be noted, providing incredibly rich, vibrant shades. To improve the aesthetic properties, glittering agents and reflective additives are used. But, as a rule, they are used for painting bicycles, motorcycles, ATVs, as well as helmets.
Proper storage
If storage conditions are not followed, the varnish will quickly deteriorate. Usually, the shelf life of a quality product is at least 2 years, but violation of the conditions reduces this time. You need to carefully read the label, which indicates the storage parameters of paintwork materials.
It is especially important to clarify the ambient temperature. Prolonged freezing renders most varnishes unusable. The product becomes cloudy, and application to furniture or the car body will lead to unpleasant consequences. Prolonged storage at high temperature causes the hardeners to thicken, and after 1-1.5 months the cylinder will have to be thrown away. The recommended temperature range must be strictly observed, then the varnish will remain fresh for a long time.
Conclusion
Car varnish is the last to be treated as a topcoat. Therefore, the degree of protection of the vehicle from adverse factors and its impeccable appearance will depend on the quality of the composition and the correct implementation of the application technique.
