Painting of walls with a spray gun: difficulties in work

When carrying out repairs,the need for decorative painting of walls. Brush it to make qualitatively and quickly it is rather problematic, and the roller does not always give exactly that result which is necessary. The consumption of paint in this case may be too large, and if its cost is high, then the total expenditure of funds will be significant, which is not always acceptable. Therefore, the option of painting the walls with a spray gun is increasingly used. This is a special equipment designed to spray paint dense jet on the surface. Thanks to the spray gun it is significantly reducedtime of painting walls and paint consumption. The surface is then perfectly dyed, there are no streaks, as are sharp band transitions, which is not uncommon when painting with a brush. Time to work is greatly reduced, and the paint consumption is minimal. The wall is covered with an even layer, the color becomes uniform and saturated. In just a couple of hours with such equipment, you can paint the walls of the entire house, without making any special efforts. It does not require a special experience of the painter, which makes the work much easier.

Tools and materials for work

To paint the walls, it is necessary to prepare such equipment and materials:

• an airbrush of the selected type;
• An electric drill with a special nozzle-mixer, which is necessary for stirring paint;
• The container for the paint in which it will be stirred, if necessary, color;
• dimensional capacitance;
• Water-based paint of the chosen color or ordinary white, for which a special pigment is prepared in advance;
• Painting tape;
• polyethylene film for protection.

Which spray gun is suitable for painting?

The scheme of the device is a spray gun. Pneumatic spray guns are professional tools, they are used for water-based paints, but can be used with other types of compounds. All parameters are easily regulated, the device itself operates on the principle of compressed air. The capacity is high and is up to 400 m² per hour. With such equipment, you can paint a large area for a day. An electric spray gun for painting is used too often. It is suitable for water based emulsions, it is powered by 220 V. The equipment is compact, easy to operate. Such a device can simply paint the walls even in a large room. Time to work a lot is not required, but the result is qualitative. To work with small areas you can use a hand-held spray gun, which is extremely simple. It is designed for water-based paint, it is a small balloon and a sprayer. During operation, pressure builds up in the container, paint through the spray gun hits the wall. Press the lever evenly so that the coloring turns out to be correct and beautiful. In addition to water-based paints, it is possible to use water-lime, water-salt solutions. The capacity is approximately 200-225 m² per hour. Nothing difficult to work with a spray gun, although before painting it is still better to practice on a piece of drywall or plywood. The equipment itself must be pre-assembled, the paint should be stirred correctly, and then the work should begin. The wall can be painted on wallpaper, plaster, you can use stencils and toning. It all depends on what kind of result you want to get. Back to contents</a>

Preparing the spray gun for work

The scheme for calculating the amount of paint needed to paint the walls of the room. To use the spray gun, it must first be properly assembled. To do this, you must follow these steps:

First, the handle and the nozzle are attached to the body of the equipment, turns until it clicks. After that, connect the air hose.

During assembly, make sure that the hoses do not bend, do not squeeze, as the supply of the composition will be difficult.

It is necessary to adjust the nozzle position for vertical and horizontal feed.

A circular regulator is adjusted, it allows to change the head of the paint supply if necessary.

It is important to immediately protect all surfaces and sockets with paint tape, as the paint can significantly damage them. The cases are carefully removed, after which the holes are sealed. Wires must be protected to avoid accidental injury. The same rule applies to door and window apertures, skirting boards, which will not be painted. When working with a spray gun,use personal protective equipment. The paint is refilled in the container, if necessary color. Before work, you should make a couple of test smears to get a uniform surface of the desired shade. The diffuser is kept strictly at right angles. The surface is covered with smooth movements from the top to the floor, you can not hold it too long in one place, since the convex elements easily trap the paint on yourself. The corners must be treated especially carefully. There is nothing complicated in this, but special attention should be given to them. It is necessary to ensure that during the surface treatment there are no unpainted places left. Back to contents</a> Painting on plaster The spray gun can be used for plastered surfaces. To do this, it is sufficient to perform a few simple steps:

First, you should prepare the container for about10 liters, it squeezes the contents of a tube with a pigment and adds the usual white paint. The mixture is thoroughly mixed to make the consistency homogeneous.

If there is a need to dilute the composition, you can add water, after which the viscous compound is mixed again.

The head of the nebulizer is attached to the equipment, it is advisable to make several test smears to determine the degree of spraying. Then you can start painting the wall.

Keep the nebulizer at a distance of 150-200 mm. The hand is set exactly, inclined movements are not allowed.

It is important to pay attention to howto paint areas near window openings. It uses a special paint tape for protection, the nozzle is best kept sloping. It is necessary to move from the middle to the corners.

It is important to make the movements smooth and smooth, it is impossible to hurry in this case, but also to work too slowly, too, since paint stains can be formed, which is difficult to get rid of.

Back to contents</a> Stencil painting The nozzle of the spray gun should be locatedperpendicular to the surface to be painted. You can paint beautiful patterns and patterns with stencil on the walls. You can make them yourself or buy already ready. The work consists in that the basic surface design is performed first, often painting or wallpapering, applying a layer of plaster. After that, carefully fix the stencil. Especially this applies to rough or uneven surfaces, textured wallpaper. The painting itself can be performed in this way:

First, a base coat of any type is applied, it must first dry out.

A stencil is attached to the wall. If it consists of several parts, then all of them are glued to butt. The edges of the picture must be pressed against the wall - otherwise the quality will be low.

After that, the spray gun on the drawing areapaint the chosen color. The consumption is set at a minimum, so that the composition does not fall under the edges of the stencil. The paint is applied by one smooth, but rapid movement.

You should wait a while toThe surface of the paint gently seized, but did not dry. The stencil is removed neatly, the paint should not be damaged. When the work with one stencil is finished, you can start painting other parts. It is advisable to use several copies at once, paint them at a time.

If the entire surface of the wall is ready, it can be covered with a colorless varnish to secure the picture. Today there are numerous varieties of such varnishes, including matte ones.

What difficulties can arise when using a spray gun?

The decoration of the wall should be of high quality,so the equipment must be able to use correctly. For example, to keep the spray gun from the wall should be at a distance of 150-200 mm, then the coloring becomes smooth and beautiful. If toning or decorative spraying is required, the distance can be increased. In order to get a smooth surface, it is recommended to practice first on a piece of cardboard or wood. It is necessary to adjust the nozzle operation, to achieve an even jet, to apply a couple of test strips in different directions. After that you can start the work. When using a spray gun for painting walls, you may encounter some problems:

At the edges appear streaks. This is due to the fact that the air flow is too strong. To eliminate the error, the air flow must be made less or for the use of a more viscous compound.

Under the middle of the spots on the wall appear abundantstains. It is explained by the excessive flow of paint. It is necessary to drastically reduce the flow through the nozzle. Perhaps the air jet should be made a little stronger.

After application, the paint stain appears to be dusty. Such a problem usually arises because the viscosity of the paint is too high. This indicates that it is necessary to dilute it to the consistency that will be suitable for work. This is also achieved by experience.

Painting the walls with a spray gun is simple and convenient. The surface is smooth and of high quality. The paint consumption is minimal, and there is not much time to work. To paint the walls you can use different types of spray guns, they are all suitable for different compositions. It is important to pre-adjust the torch, air flow, so that the jet was not only flat, but also correctly covered the surface, there were no streaks and traces of dust. </ ul>
