Choosing a battery spray gun

Often you are faced with the problem of working conditions in which there is no access to the electrical network. For example, when it is necessary to paint an object or surface that is located somewhere in an open area far from home. And it is simply impractical to stretch network extension cords for several tens of meters. To solve this problem, rechargeable spray guns were created that operate on a battery and do not require connection to an outlet.

The cordless spray makes it possible to evenly apply paint to a wide variety of surfaces - wood, metal, concrete, glass and others. The essence of the work of this tool is that the paint from the reservoir is supplied to the gun under pressure, which occurs after starting the power supply through the battery. There are models on sale that work not only from a battery, but also from an electrical network, this will be indicated in the technical characteristics of the tool.

Today the use of paint rollers and brushes is a relic. People are trying to keep up with the times, especially since the invented battery tools are aimed at making it easier for a person, plus the quality of the result of the activity is much higher, and labor costs are less.

Modern spray guns have a number of features that attract potential buyers.

• The ability to operate the spray gun without access to the mains. The device operates on a battery - the main thing is to ensure that it is fully charged before starting work. Therefore, it can be used to paint outdoor objects such as a swing in a yard, a gazebo, outside walls of a house, and more. And also a fully charged tool will become an indispensable assistant where, for some reason, there is no electricity.
• Lack of wire. Working with a cordless spray gun, you do not need to constantly correct and carry the wire, thinking where to move it so that it does not interfere with your work.
• Independence from voltage drops in the electrical network. But often, voltage drops caused damage to electrical tools, which after that could not even be repaired.
• Complete freedom of movement for those who use this tool. There is no stiffness due to the cord that always gets tangled under your feet. This also affects the result of the work, which turns out to be much higher.

However, with all the advantages of using a cordless spray gun, there are a number of its disadvantages.

• Limited running time - several hours (until the battery is completely discharged, depending on the model). Often this time is not enough to completely finish painting a large object. In this case, you should foresee a way to recharge the battery, or take a spare one.
• Low battery level affects paint quality, as the pressure under which the paint is fed into the gun is reduced. You should not work on the device when the charge level begins to drop significantly, as this affects the quality of work: drips, uneven spray layers, and so on may appear.
• Significant tool weight. Due to the presence of a battery, the spray gun has a significant weight. Therefore, when working with them, it is necessary to take this into account, since untrained people can quickly get tired, holding the device in their hand for a long time.
• Battery powered models have less powerthan on similar tools that operate on mains power.

A battery-powered paint sprayer makes it possible to paint objects that are far from the electrical network - on the street, in the basement, in places where there is no electricity.

Any cordless spray gun consists of 3 parts:

• gun - sprays paint on the surface;
• reservoir (tank) - coloring matter is poured into it;
• battery - the power supply unit of the device.

When buying a cordless sprayer, as with choosing any other tool, you need to pay attention to its technical characteristics. They help to establish its capabilities and potential in work. It is not enough for him to simply spray paint - it is necessary that he does it with the required quality, duration of work and power supply of the dye.

When choosing this tool, you should pay attention to a number of factors.

• The scope of the proposed work. If you need to finish work as soon as possible, then you should choose models with a large battery capacity, such models are more nimble. You should be aware that the performance of the tool also affects its cost, that is, the more efficient the sprayer is in operation, the higher its price will be. If you don't care about the time you spend on painting the required object, feel free to choose cheaper models. In any case, a cordless spray gun is faster than a roller or brush.
• The volume of the paint reservoir. The larger it is, the more convenient it is to work with large areas. However, the runtime depends on the power supply anyway, so it is better to have a spare battery with you. Remember that the large volume of the tank affects the weight of the unit, which will be felt during prolonged use.
• Scope of application. If you intend to use a cordless spray gun once every several years, then it makes no sense to choose models with a large number of functions. After all, the breadth of the functionality directly affects the cost of the device. In this case, you will simply overpay a significant amount. But buying the cheapest Chinese model is also not worth it, because no one wants to buy a new spray gun in 1-2 years.
• As you study the technical specifications, pay attention to the types of surfaces on which you can use the device - the wider it is, the better. After all, you never know what will need to be painted. It is also important how many painting modes the device provides.
• Build quality is equally important. If you want to purchase a tool that will serve you for more than one year, you need to choose products from trusted manufacturers. Today, the brands Graco, Bort and Ryobi have proven themselves best.

Before pouring the colorant into the tank, you need to check if it is suitable for your spray bottle. If the paint is too thick, it is diluted by 5-10% with a special solution, and a viscometer is used for control, which comes with a spray bottle. The viscosity of the paint is measured as follows: we dip the measuring dispenser into a can of paint, and it should leave the funnel of the viscometer in 20, maximum 30 seconds, if it has time to do this, then this type of paint is suitable for your spray gun. In order to start working on the tool, it is necessary to disconnect the reservoir and fill it with paint.

And the tube, which is inside it at an angle, must be turned in the direction where the paint will be. It depends on whether you are painting the ceiling, floor or wall. Then we connect the tank to the spray gun. Don't forget about personal protective equipment. The distance from the surface to the spray gun should be no more than 30 cm, ideally 15-20 cm. First, you need to carry out a test spraying to adjust the paint supply, and only then you should start painting the main surface.
