Apartment renovation is not complete without painting. Most often, walls and ceilings are painted.

With high ceilings or large paint areas, the application process with rollers or brushes becomes laborious and time-consuming.

A spray gun or spray gun can help you out.

Painting the ceiling with a spray gun not only reduces painting time, but also allows you to create a high quality surface.

But you need to be able to choose the right spray gun model.

Main advantages of paint spray guns for water-based paint

The use of spray guns for water-based paint significantly reduces the painting time.

The surface to be painted is obtained with a thin, uniform layer.

When spraying, no streaks or streaks remain on the surface.

The minimum paint layer thickness will significantly reduce the drying time.

The process of painting surfaces of complex curvature, such as skirting boards, baguettes, is greatly facilitated.

The presence of extension cords allows painting of a high ceiling surface from the floor.

Paint sprayers are equipped with a set of replaceable nozzles. Nozzles are paint spray nozzles.

Spray gun types

Spray guns for water-based paint are divided into three types: manual, electric, pneumatic.

And which spray gun to choose for painting with water-based paints?

The difficulty is that low pressure is difficult to achieve a fine grain spray. The problem is that when using water-based paints in an apartment, drying does not occur as quickly as with paint based on solvents.

The difficulty of choosing a spray gun is to choose a side-altar between thinner water and paint coverage.

If you install a nozzle with a larger diameter, then it is permissible to use a thicker composition. And if there is not enough pressure, then coarse grain will form on the surface or the paint will not go into the sprayer. This is especially true for electric spray guns.

Hand-held spray

guns Hand-held spray guns are devices that consist of a spray gun in the form of a rod, container, hose and pump. Most often, the tank and the pump are combined into one whole.

With the help of a pump, an excess pressure is created in a container with a water-based paint. The paint is supplied under pressure through a hose to a spray gun attached to the end of the rod.

Paint sprayers of this type allow painting up to 200 … 250 m² of area per hour.

The main advantage of this type of spray guns is their simplicity, low cost, ease of maintenance.

Spray guns for water based paint are excellent helpers when painting ceilings with lime or chalk water solutions. The disadvantage of spray guns of this design is the coarse graininess of the painted surface. Pros - the ability to pass small particles of the whitewash fraction.

To reduce graininess, it is recommended to use high-quality water-based solutions. Well, do not forget about controlling the viscosity of the paint used.

By the way, a few words about viscosity

Viscosity is a scientific term. But in simple terms, this means how the liquid resists when flowing through any hole. The lower the viscosity of the liquid, the faster the coloring matter is ejected through the nozzle of the spray gun. The viscosity value affects the grain size of the treated surface.

Viscosity is measured in seconds by special devices called viscometers.

From hand-held paint sprayers, the KSOM KRDP-4 018-1031 spray gun can be recommended.

Electric paint sprayers are devices that spray paint in two ways: airless spray and low pressure spraying.

Structurally, electric paint sprayers are made in housings that visually resemble a hair dryer, at the end of which there is a dye spraying unit, and a container with paint is attached from below. The devices operate from a 220 V alternating current network. Their operation does not require additional devices and equipment.

For work at height, it is preferable to use electric spray guns. They are autonomous and easy to use.

The main disadvantage is that when painting walls, you have to dilute acrylic paint with water, reduce its viscosity. At low viscosity, the density of the paint solution decreases and reduces the coverage of the ceiling and wall surfaces. This forces you to apply multiple layers of paint to the surface.



Airless sprayers work by creating increased pressure by the main unit of the device - a plunger pump. An increased pressure is created in the container and this will ensure the speed of painting and high quality of the painted surface.

Painting units The

equipment is a composite device, which has a manual spray gun, a pump with pneumatic drive for supplying paint solution, heaters, filters, connecting hoses, carts.

The cost of airless paint sprayers ranges from 20 thousand rubles.

The best device is the Wagner Paint Crew installation.

In low-pressure spray guns, an air flow of up to 1 atm is created by a built-in pump or compressor.

Low-pressure spray gun for painting works from an alternating current with a voltage of 220 V. The mass of such a device does not exceed 1.3 kg. The pneumatic low pressure paint sprayer is completed with a tank up to 0.6 l. The cost of this type of spray gun does not exceed 4 thousand rubles.

The best brands of electric spray guns are Wagner, Paint Zoom, Bosh, Balack & Decker, Elmos and others.

The best are the models of the Bosh brand: for example, the Bosch PFS 65.

This model includes a spray gun, a remote compressor and connectable hoses. A 0.6 liter tank is attached to the bottom of the spray gun.

Compressor power 280 W.

Spray gun productivity 130 ml / min.

The cost is about 6000 rubles.

Pneumatic spray


guns Pneumatic spray guns are devices in which the coloring matter is sprayed by supplying compressed air under high pressure.

The pneumatic paint sprayer consists of the spray gun itself with a tank for paint, a compressor and connecting hoses.

In pneumatic spray guns, containers for colorant can be located both from the bottom and from the top.

The productivity of pneumatic paint sprayers is 400 m² per hour.

Pneumatic paint sprayers are divided into three types according to the dye supply technology:

1. By HP technology, in which paint is sprayed with air under pressure up to 5..7 atm and in its large volume. This is an outdated technology. With this spraying, no more than 50% of the paint gets to the surface. But due to the low cost of spray guns, the technology is still in demand.

2. By HVLP technology, in which the paint is carried by air at a pressure of less than 1 atm. and its great expense. This technology increases the color transfer by up to 70%. Such spray guns cost at least 1,500 rubles.

3. By LVLP technology, in which paint is supplied with low pressure air at a minimum consumption. This technology allows you to transfer up to 90% of the dye without increasing the speed of work. But the cost of spray guns of this technology can reach 12 … 15 thousand rubles.

The most common models of pneumatic spray guns are Sata and Interpool.

The most popular Russian spray gun is the SO-71 sprayer. But the passport does not indicate the possibility of operation of the specified sprayer with water-based paint.

It is best to use a pneumatic spray gun to paint walls and ceilings.

How to choose a spray gun for water-based paint?

When choosing the type and model of the spray, give preference to spray guns designed to work with water-based paints.

When choosing nozzles, pay particular attention to the body material. Give preference to models with an aluminum body covered with a corrosion-resistant nickel layer.

But the service life of the plastic case is not great, although its weight is much less.

The nozzle cover should be made of aluminum, brass or stainless steel.

The gaskets must be made of Teflon. This will prevent solvents from attacking the gaskets.

The paint containers are made of both metal and transparent nylon, which allows you to control the paint level.

If you are not a professional, it is better to get the simplest tool. The simplest paint sprayer costs from 500 rubles. Professional spray guns cost more than 3500 rubles.

Which spray gun is better for painting the ceiling?

You can paint high ceilings either from the scaffolding or from the floor.

If you plan to paint off the floor, it is best to use a handheld rod-style spray gun.

But painting the ceiling with water-based paint with a spray gun from the scaffolding is carried out with an electric paint sprayer, which is not only lightweight, but also able to work autonomously.

Painting the ceiling with a spray gun allows you to get a high-quality surface, a uniform and thinnest paint layer.

Preparation of painting material

Painting work begins with the preparation of the paint solution. To prepare an aqueous emulsion solution, water is added to the beauty, the mixture is thoroughly mixed using an electric drill with a nozzle. A whisk or a construction mixer is used as a nozzle.

Color is added to the thoroughly mixed solution. Kohler should be added to the solution in small portions, stirring constantly until stains are excluded.

Do not forget! The paint must be prepared with a margin. If you don't have enough paint, it will be difficult to guess with the new color scheme.

Remember! The paint in the liquid state has a deeper and brighter shade than that of the dried on the surface.

Paint consumption is calculated on the basis that 1 m2 of surface will require up to 0.5 liters of paint solution.

How to use a paint sprayer correctly?

When painting the walls in an apartment, be sure to start painting from the corner and continue to the next corner without stopping so that differences and shades are not obtained.

how to paint correctly
how to paint correctly
  • Using a spray gun, observe the inclination of the jet towards the surface to be painted. The jet should be directed strictly perpendicular to the painting surface from a distance of no more than 70 cm to the surface. The recommended distance is 50 cm.
  • The movements of the spray gun should be uniform, circular, spiral. Try to keep a constant pace, do not paint over the same areas twice.
  • Painting the surface with acrylic and water-based paint must be done in two layers. The second layer is applied after the previous layer has completely dried.


  • purchase paint sprayers, the passport of which indicates the possibility of working with water-based paints;
  • for work at height, give preference to electric paint sprayers;
  • it is more expedient to buy spray guns in an aluminum case;
  • for one-time work, it is better to use a cheap manual spray gun; for large volumes of painting work, you cannot do without a pneumatic spray.
