How to Use Spray Guns

Spray guns serve as an alternative to traditional paintbrushes for completing an indoor or outdoor paint job. Some consumers prefer spray paint because it is quicker and cleaner to apply to a wide range of surfaces. When using a spray gun, messy paint pans are a thing of the past, as is worrying about paint dripping all over the place. However, painters must be familiar with proper application techniques, as well as how to operate the equipment to get the results they want with a spray gun.


Area preparation

Since spray guns apply paint in the form of a mist, it is necessary to cover or remove any aspects of the area that should not get paint on them. Use tarps to cover the floors and painter's tape to shield windows and walls. Plastic trash bags and old newspaper are useful for covering any furniture or valuable items that one is unable to remove from the area. Paint mist can travel long distances, so even objects and surfaces on the opposite end of the room require protection from airborne paint particles.


Practise with water

To achieve the best paint job, it is important to master the correct technique and make sure the spray gun itself is in proper working order. Filling the tank with water and practising evenly covering a surface is a great way to learn how to use the gun before bringing the paint into the picture. It also provides an opportunity to experiment with holding the equipment in different positions to determine which is most comfortable.


Paint preparation

Paint used in a spray gun must be free of dried clumps of paint or any particles that may have fallen into the can during previous use. To remove any particles that can prevent the paint from applying smoothly, run it through a strainer. Then, before pouring the prepared paint into the tank, use paint thinner to achieve the correct consistency.


Pressure level

Spray guns are capable of spraying at various pressures, depending on the painter's preferences and which setting produces the desired look for the job. Use the pressure control knob to set the gun to the lowest pressure setting, and then spray a test strip onto a piece of scrap material, such as a cardboard box. Gradually increase the pressure setting until you find one that produces the desired paint pattern.


Proper painting techniques

There are three main aspects of their spray technique that painters must take into consideration to produce a quality paint job. These include:

  • triggering technique
  • spraying distance
  • overlapping technique

Triggering the gun

A common mistake is to press the trigger and begin moving one's hand at the same time, then release the trigger at the end of the stroke. However, this causes thicker application at the beginning and end of each stroke, resulting in an uneven paint job. Instead, begin moving your hand before pressing the trigger to begin spraying so that the paint applies with the same thickness throughout. Then, continue moving your hand after finishing the stroke before releasing the trigger.

Application distance

Another mistake that results in uneven application is spraying at varying distances. It is important to maintain approximately the same distance the entire time to achieve an even coat. In most cases, one should hold the gun about 0.30 metres from the surface, although different distances can create different thickness levels.

Overlapping strokes

Overlapping is an essential technique that helps produce an even coat that is free of visible lines between strokes. To utilise the overlapping technique, begin a new stroke by aiming the gun at the top or bottom of the previous stroke so that the new stroke overlaps half the width of the previous one. It is also helpful to cover the outside edges of the surface first when painting a large area, such as a wall or ceiling. Doing so makes it quicker to apply overlapping strokes inward toward the centre of the surface.
