Top 3 spray paints for wood and rules of application
Spray paint is an enamel, placed in a jar, ready to use. It is applied to the surface by spraying. Spray paints for woodworking are widely represented in the construction market segment. Spray cans, in addition to the high reliability of the paint, provide a thin layer of enamel on the surface. You won't get such an even coat if you work with a roller or brush.

Main varieties
All spray paints and varnishes are divided into:
- acrylic;
- alkyd;
- nitrocellulose.
Each of the varieties has its own advantages and disadvantages. But they are all suitable for working on any surface. Can be sprayed on wood, concrete, brick. Spray paint has high adhesion properties.
Consider each of the groups separately.
Acrylic sprays
These are products based on acrylic resins and water. These are polymer sprays. Additives may be present to improve the performance of the aerosols. Suitable for outdoor and indoor use.

- Ease of use. No special skills or abilities are required to work with sprays.
- Does not fade. The alkyd composition is resistant to sunlight. It is not affected by long exposure to ultraviolet rays.

The aerosol can be used and set aside until you need it next time. This is the hallmark of the sprays. And the paint in pots after opening quickly thickens and becomes unsuitable for painting.It must be diluted with solvents to do the job.
Alkyd based
Alkyd spray cans are made of resins, alcohols, acids and pigments. Antiseptic and antifungal additives are present. When sprayed on wood, they form a protective film that guards against the development of fungus and mold.

- Resistant to humidity and aggressive environments.
They have a shorter lifespan than acrylic. After about a year, the painted surface will need to be renewed.
Important. Before spraying, the wood product must be primed. This will improve the adhesion of the varnish to the grain of the wood.
Nitrocellulose glazes
These aerosols are made from resins, colloxin, organic solvent. They have a pungent smell. You can work indoors. After graduation, you need to vent everything properly.
The products have many advantages:
- They protect well from the weather.
- Stable against extreme temperatures.
- Resistant to mechanical stress.
- Dry quickly. The drying time is one hour.
- Are cheap.
The disadvantages include a poisonous odor, because of which in some countries the use of such products is prohibited.
Designed for furniture restoration, for the treatment of decorative and laminated surfaces. They are used as a finishing coat for varnished natural wood surfaces. They can be colored and transparent.They have a glossy or matte sheen.
Application rules
The use of aerosols in bottles is quite simple and does not require special skills.
Attention. The room should be well ventilated. Do not forget the protective measures (glasses, masks).
- It is important to prepare the wood for painting. Clean dirt and degrease. It can be done with an alcohol solution, a solvent. You can walk on wood with sandpaper.
- When painting with alkyd varnishes, the wood must be primed. Otherwise, the enamel will not adhere to the surface.
- We are waiting for the tree to dry out.
- To avoid getting paint on surrounding objects, cover them with aluminum foil or newspapers.
- Shake the ball well, hear the sound of the ball.
- We perform a spray test in an inconspicuous location.
- Spray from a distance of not more than 30 centimeters, but not closer than 20 cm. It is best to place the product horizontally. This will prevent stains and streaks. If the wooden structure is vertical, spray from top to bottom.
- We hold the ball vertically upwards.
- With a rag, we immediately remove defects in the work, repair defective places.
- Spraying is done evenly, in a thin layer. If necessary, apply a second coat after 20 minutes.
- If not all the varnish has been used, then you can clog the canister by first cleaning the sprayer.
Important. The wood on which the coating will be made is taken dried. Otherwise, the adhesion will not lock, the paint will peel off quickly.
Disadvantages of application and possible difficulties
When working with such a product, remember that the aerosol is very volatile. It spreads toxic substances in space.Therefore, work should be carried out in ventilated rooms. In this case, one should not forget about compliance with personal protective measures. When painting, a person wears special work clothes, rubber gloves, goggles, a hat and a respirator. There is a high probability of inhalation and ingestion of paint vapors.Toxic substances spread through the air, therefore only a gas mask or respirator can protect against the harmful effects of aggressive chemical elements.
Important. Do not work near naked flames!
Another disadvantage of spray cans. Compared to canned paints, aerosols do not have such a wide color palette. It will be difficult to find a specific shade for a particular job.
Selection tips
Woodworking involves its own nuances and subtleties. Since its safety depends on air temperature, humidity, sun exposure. Without special treatment, it will crack and lose its appearance. Therefore, you can not do without painting with sprays.
It is better to choose acrylic sprays because they are odorless. And not as toxic as the other options. Acrylic paint is the fastest drying. In 20-30 minutes after the end of the work, the coating will no longer stick. Acrylic sprays are available in more shades. Therefore, it is easier to find a suitable color.
It is necessary to pay attention to the type of work you will be doing. Depending on whether it is outdoor or indoor work, the type of cylinder is chosen. For outdoor use, an alkyd spray is best suited. Acrylic is chosen for operations in the house. Canned sprays are a great alternative to conventional canned glazes.
