Paints and varnishes in cans are especially popular, due to their ease of use, the creation of a thin coating, and the absence of the need to purchase additional tools for painting. But aerosol products are not always suitable for repair work, so before choosing an option, you should evaluate all aspects of the application. Aerosol varnish, when it is best to use it and the nuances of the material will be discussed in the article.
Why is it worth protecting a tree using paints and varnishes?
Due to its characteristics, wood requires special processing. The condition of the material is negatively affected by:
- precipitation;
- temperature changes;
- ultraviolet.
The lack of protective treatment exposes the tree to aggressive environmental factors. Because of this, the material quickly deteriorates: it rots, cracks and dries out.
Why do aerosol coatings have more advantages?
When working with aerosol varnish, you will definitely not encounter common problems that arise during surface treatment of paintwork materials. As a rule, the usual compositions:
- difficult to apply, and achieving uniform distribution of the layer over the surface is almost impossible;
- leak;
- takes a long time to dry;
- require the purchase of additional equipment for application (roller, brush, etc.).
When working with such varnish, all these problems disappear. In addition, there is no need to select a paint, getting confused in a large assortment, because paintwork materials for wood in the form of aerosols, for the most part, are suitable for processing wood.
Variety of wood varnishes in cans
All varnishes are divided into several categories:
- water based;
- acrylic;
- polyurethane;
- nitrocellulose (NC 218).
These sprays are characterized by such advantages as:
- fire safety;
- environmental cleanliness;
- hypoallergenic;
- no odor;
- drying in a short time;
- strength of the formed layer;
- elasticity.
Please note that water-based aerosols are characterized by such a negative quality as moisture resistance.
Polyurethane compounds are made from polyesters and diisocyanates. They differ from others not only in strength and elasticity, but also in resistance to chemical and physical influences. Depending on the composition of this type of wood varnish in cans, they are divided into two types: one- and two-component.
As for acrylic varnishes, after drying, such a spray forms a fairly durable layer on the surface of the wood. This is the best varnish option for treating wood surfaces. The result of dyeing is a natural color, close to the shade of wood, without yellow spots and bubbles. Please note that this coating option is not suitable for treating the internal surfaces of baths, saunas and bathtubs, since acrylic is sensitive to water.
The composition of nitrocellulose varnishes includes organic mixtures, resins and colloxylin. This spray coating option is suitable for residential applications. It dries quickly (no more than an hour), does not emit harmful substances, which means it is safe for humans.
NTs 218 is an aerosol varnish for wood in cans, which is hard and has excellent decorative properties. It is suitable not only for processing lumber, but also for painting cars.
General information. Varieties
In stores today you can buy a very popular water-based varnish. This type includes polyurethane and acrylic varnish, which is incredibly popular because it is safe, environmentally friendly and non-flammable. Their main advantages:
- There is no aroma at all.
- Once applied to the surface of wood, paint or metal, these types dry out extremely quickly.
- Create an extremely durable and thin protective layer.
- The coating can be elastic.
Please note that one of the main disadvantages of this type of varnish composition in a cylinder is that it is not resistant to moisture.
Which spray is better: clear or colored?
Clear varnish is the most commonly used. It's all about its versatility. It is practically invisible on the surface of the wood and does not hide the natural grain of the wood.
This is the best treatment option for expensive woods such as oak, mahogany or beech.
For cheaper types of wood, colored aerosols are predominantly used. Using a colored spray, you can easily hide some surface problems and not just protect it. In addition, it will help create an expensive, noble look for furniture made from simple lumber.
A wide palette of colors allows you to choose any shade that suits your interior style. When buying an aerosol, consider:
- Absorbency properties of spray varnish. For example, water-dispersed compositions do not penetrate so deeply.
- Gloss level. The stronger it is, the more pronounced the surface looks.
Popular colors include white and black paintwork materials. White varnish allows you to achieve a touch of gloss and severity on the surface of the wood. In addition, white tones are ideal for light-colored surfaces and parquet.
Which is better - glossy or matte?
Glossy types are good for rooms in dark colors. They give the furniture a spectacular shine and emphasize the contrast of lines and patterns. Any mechanical damage on a glossy surface will be more noticeable.
However, durability does not depend on whether the spray is matte or glossy. This characteristic depends more on the manufacturer and workmanship. More expensive models usually have better features.
The matte spray makes cleaning easier and requires less maintenance. These paint cans are quite economical.
Matte varieties are an excellent option when you want to achieve a natural paint finish. The products will need to be sanded more carefully, but the final result will be aesthetically pleasing.
Features of odorless varnishes
For most buyers, the lack of odor and safety of the varnish for humans is the leading criterion in their choice. The hypoallergenic nature of the emulsion is especially important for those who suffer from respiratory diseases. Therefore, you should avoid long stays in the room where the treatment was carried out with aerosol paints and be sure to wear a protective mask.
Some of the harshest varnishes in cans include:
- alkyd;
- polyurethane;
- nitrocellulose.
When purchasing a spray can for treating surfaces in a children's room, make the product's environmental friendliness the main selection criterion. It is worth paying attention to water-based acrylic compositions. This is a harmless aerosol without foreign odors, but just as durable and elastic as others.
Aerosol varnish - what is meant by this
The varnish in the can is supplied by pressure; finely broken particles of paint and varnish material come out of a special nozzle, which settle on the surface, creating the necessary protective and decorative layer on the base.
During work, the master must monitor the distance to the surface so that it does not change, and the speed of movement of the can so that the layer can be distributed evenly.

There are many compounds on sale in heat-resistant cylinders, with protection against rust formations, as well as biological ones.
Among the disadvantages are the following:
- It is necessary to monitor the thickness of the layer; a coating that is too thick will not have good protective properties, and the layer will also take longer to dry;
- Sometimes the spray tip on an aerosol breaks, or the gas runs out, then the varnish cannot be used;
- It is necessary to ensure dust-free drying of the layer.

Aerosol can device
Paint varnish in cans has the same principle of structure and action. The cylinder has a concave bottom to create protection from excessive pressure. Inside the container is loaded with paint, inert gas, and a special tube that allows the composition to come out. A valve is installed at the top point, which serves as a spray safety valve, which can only occur after pressing the valve.

Varnish storage conditions
A high price for a product does not always guarantee the quality of the product. Sometimes branded aerosols turn out to be cheap fakes that are good for nothing. You can get into the “duck” by buying varnish at a stall on the market. Remember once and for all - any building or finishing material should only be taken from a specialized store or construction center.
Sometimes the composition becomes unusable due to improper storage. The shelf life of such materials is 24 months from the date of production, but only if properly stored in compliance with the temperature and humidity levels in the room.
How to properly store varnish spray in a can?
Recommendations regarding storage conditions are contained on the label affixed to the wood varnish in the can. When studying the details, pay special attention to permissible temperature differences that do not adversely affect the suitability of the composition. Having studied this criterion, you will immediately understand whether it is worth purchasing such a spray at a retail outlet. Thus, all cylinders sold on the market are stored at ambient temperature in the summer, and in winter these indicators can drop to -20 ° C, which already exceeds all permissible standards. Therefore, such material, even if it has just been produced, deteriorates after 1-2 weeks, losing its qualities.
By using expired or spoiled varnish, you risk damaging the surface of the wood being treated, which, as a result of exposure to such varnish, will become covered with bubbles, stains or wrinkle.
Now you can figure out which aerosol varnish for wood is best to buy, and how not to make a mistake with your choice.
