repairs in the apartment is not without painting.Most often painted walls and ceilings.
With high ceilings and large area painting process is the application of the colorant using a roller or brush it becomes tedious and time consuming.
help you can airbrush or spray gun.
Stained ceiling spray gun not only reduces staining, but also allows you to create high-quality surface.
But you should be able to choose the right model spray gun.

main advantages of spray guns for water based paint

use dispensers of latex paint significantly reduces staining.
The surface is obtained with a thin, uniform layer.
When sprayed on the surface does not leave marks or streaks streaks.
minimum thickness of the painted layer significantly reduces the drying time.
greatly facilitates the process of staining surfaces of complex curvature such as skirting boards, moldings.

Availability extension allows staining situated high ceiling surface from the floor.
Guns are equipped with a set of replaceable nozzles.Nozzles called the nozzle spray paint.

types of spray guns

spray gun for water-based paints are divided into three types: manual, electric, pneumatic.And what
choose airbrush for painting with water-soluble paints?
The difficulty is that the low pressure is difficult to achieve fine particulate dispersion.The problem is that when using a flat water paints is not dry as quickly as solvent for paint.
complexity of the gun of choice is to choose between the chapel of the diluent water and coating properties paint.
If you put the nozzle of larger diameter, it is permissible to use a thicker structure.And if there is not enough pressure on the surface will form a large grain or paint will not go into a spray bottle.This is very important especially for the electric spray guns.

Hand airbrushes
Hand gun KRDP - 4-2
Through manual airbrushes are devices consisting of a nebulizer in the form of rods, tanks, hose and pump.Most often combined container and pump in one unit.
With the help of the pump creates a positive pressure in the tank with water-based paint.pressure paint through the hose supplied to the spray gun fixed to the end of a fishing rod.
similar type airbrushes allow you to paint up to 200 ... 250 m² per hour.
main advantage of this type of spray guns in their simplicity, low cost, ease of maintenance.
spray gun for water-based paints are great assistants when painting ceilings limestone or chalk aqueous solutions .The disadvantage of spray guns of this design is a major grain painted surface.Plyusy- ability to pass small particles fraction whitewash.
recommended to use high-quality water-based solutions to reduce graininess.And do not forget to control the viscosity of the paint used.

By the way, a few words about viscosity

A device for measuring the ink viscosity

device for measuring the viscosity of the ink

viscosity - the scientific term.But in simple terms, this means a fluid resists flow when passing through any hole.The viscosity of the fluid is less that faster colorant is ejected through the nozzle of the gun.The value of the viscosity affects the grain surface to be treated.
Viscosity measured in seconds by special devices, called viscometers.

from manual spray guns can be recommended gun KRDP HMAC-4 018-1031.

Electric airbrushes

Electricity Grid airbrushes are devices that provide the paint spraying in two ways: airless spraying and spraying due to low pressure.
Structurally electric paint spray guns made in the case, visually reminiscent of hair, which is located at the end of the spraying unit of the colorant, and the bottom is mounted a container of paint.The instruments operate on AC 220 V. Their operation does not require additional devices and equipment.
for work at height is preferable to use electric air-brush.They are self-contained and easy to operate.
The main disadvantage is that when painting walls is necessary to strongly diluted acrylic paint with water to reduce its viscosity.With low viscosity dye solution density decreases and reduces the surface coating properties of the ceiling and walls.It makes you put on the surface of multiple layers of paint.

Airless sprayers work by pressurizing the primary node device - plunger pump.The tank is pressurized, and this will provide the color speed and high quality of the painted surface.

airbrushes Pneumatic
conventional spray
pneumatic devices called air-brush, spray colorant which is carried out by compressed air at high pressure.
pneumatic spray gun consists of the gun with a tank for a paint compressor and connecting hoses.
The pneumatic spray gun capacity for colorant can be located both below and above.
performance pneumatic spray guns is 400 m² per hour.
Pneumatic Guns for feeding colorant technologies are divided into three types:

    1. According to HP technology, in which the paint is sprayed by air pressure to 5..7 bar and a large amount of it.This is an outdated technology.In such spraying the surface gets not more than 50% of the ink.But because of the low cost of spray guns, the technology is still in demand.
    2. By HVLP technology where ink is transferred to air at a pressure less than 1 atm.and its great expense.This technology increases the transfer of the colorant to 70%.There are such spray guns are not less than 1500 rubles.
    3. By LVLP technology, in which ink is supplied the low pressure air at a minimum flow.This technology allows you to transfer up to 90% of the coloring material, without increasing speed.But the cost of spray guns of this technology can reach 12 ... 15 thousand. Rub.

most common models of pneumatic spray guns brands Sata and Interpool.
most popular Russian sprayer spray gun is considered to be CO-71.But in the passport is not specified an opportunity to work with the said water-based paint sprayer.

best to use pneumatic gun for the painting of walls and ceilings.

How to choose a gun for water-based paint?
choosing the type and model of the nebulizer, prefer spray gun, designed to work with water-based paints.

When choosing spray material, pay particular attention to the case.Preference was given to models with aluminum body coated with corrosion-resistant nickel layer.
But the life of the plastic body is not great, although it weighs significantly less.
nozzle cap should be made of aluminum, brass or stainless steel.
gaskets should be made of Teflon.This will prevent corrosion linings solvents.
ink tanks are made of a metal and a transparent nylon, which allows to control the level of ink.
If you are not a professional, it is better to buy the easiest tool.The easiest spray gun is 500 rubles.Professional paint spray guns are more than 3500 rubles.

And what better airbrush to paint the ceiling?
Painting high ceilings can be either a forest or on the floor.
If you plan to paint the floor, it is best to use a hand gun in the form of rods.
But painting the ceiling latex paint spray gun with an electric paint sprayer is made of forests, having not only low weight, but also the ability to work autonomously.
Color ceiling paint sprayer allows to obtain high quality surface, and even the thinnest layer of paint.

Preparation of paint material

Painting work begins with the preparation of the coloring solution.To prepare the aqueous emulsion solution in the beauty of water is added, the mixture is thoroughly mixed using an electric beater.As the nozzle is used whisk or mixer construction.
The thoroughly mixed solution is added to the color scheme.Kohler in the solution should be added in small portions, stirring constantly to exclude divorces.
Do not forget!The paint is necessary to prepare a reserve.If you run out of paint, then it will be difficult to guess with the new color scheme.

Remember!We paint in liquid form shade deeper and more vivid than that of the dried surface.

ink consumption is calculated on the basis that 1 m² surface will take up to 0.5 liters of solution coloring.

How to use a paint sprayer?

When painting the walls in the apartment have to start painting from the corner and continue to the next corner without stopping to not receive drops and shades.

how to paint

  • Using a spray gun, follow the slope of the jet to the surface to be coated.The jet shall be strictly perpendicular to the surface of the dye to the surface from a distance of no more than 70 cm. The recommended distance is 50 cm.
  • Movement of the gun must be uniform, circular, spiral.Try to keep a constant pace, not to paint twice the same areas.
  • staining the surface with acrylic and water-based paint is carried out necessarily in two layers.The second layer is applied after drying the previous layer.


  • purchase airbrushes, the passport which indicates the ability to work with water-based paint;
  • for work at height, give preference to an electric paint sprayer;
  • better to buy spray guns in an aluminum casing;
  • for disposable work better to use cheap manual spray gun, with large volumes of paint work without air sprayer is indispensable.
