Paint Spraying

By using a spray gun to apply paint can be faster and easier than other methods and can give an improved finish. Some chemicals – car body surface finishes, for example – are specially formulated for bringing out; other paints can be sprayed provided that they are really ‘thinned’ with solvent.

Good spraying requires a reasonable degree of skill and knowledge both about the paint you’re applying and the paint spraying equipment itself.

Types of aerosol gun

There are two main types of bottle of spray gun: with separate air compressors or airless.

Spray firearms with separate compressors 

These are generally the conventional design of spray gun. Originally, they had large compressors plus a bulky ‘receiver’ to balance out fluctuations in pressure. This type of equipment can still come (or hired), but the amateur is more likely to be enthusiastic about one of the range of smaller guns with independent compressors. The compressor, which is electrically powered, supplies a supply of air under pressure to the weapon which has a box for the paint. A few of the air passes into the paint container to pressurise the paint; the rest comes out through the nozzle as a fine stream. When the gun’s trigger is pulled back again, a needle valve behind the nozzle is opened up and the paint goes by up from the box past the needle and in the air flow. The paint mixes with the air flow to realise a fine spray from the nozzle. The amount of car paint that flows can be manipulated by the result in the further that the trigger is pulled again, a lot more paint that moves – though in practice the amount is limited by the power of the compressor.

Airless squirt guns

These have all their working parts within the gun unit and have no separate air compressor. The paint is required directly out of the gun with an appui which vibrates forwards and backwards, being driven by a power colonne. It requires a significant pressure to force the paint out of the nozzle and the quantity of coloring can be varied by adjusting a knob which alters the length of the piston stroke, though this is generally a fiddly operation. Obtaining a very line spray on an airless gun is difficult since the coloring should be pressurised to a certain level to skin gels any spray by any means.

Sweltering guns are more small and cheaper than distinct compressor guns, nonetheless they do have disadvantages:

– the vibration of the cilindro can make it loud and uncomfortable to keep

– an airless weapon can ‘splutter’ paint when the level in the container is low. This could ruin a practically completed job and it is not particularly easy to sec when the color containers are receiving empty. (When spray guns with individual compressors gel empty, they simply produce I apply with less and less paint)

– because the paint can come away of a gun at extremely high pressure, we have a danger of ‘injecting’ your skin with paint if placing a finger too near the nozzle. This is an important injury as the paint can spread away under skin. It is difficult to treat, but requires immediate medical treatment it is important to make clear to the person that is treating you just what has happened. Most high-pressure airless guns have security cages round the nozzle to prevent this going on.

For bodywork repairs on cars, small aerosol bottle of spray paint cans can be obtained. These types of are being used in quite similar way as spray guns. Both equally primers and topcoats are available – it is important to learn just what coloring shade your automobile is. Although convenient to use, aerosol solutions are an expensive way of covering anything besides small areas.
