You’ve heard the term, now it’s time to discuss and fully understand what it is. This week we answer the increasingly popular question – what is spray painting? We discuss exactly what it is, the different techniques that spray painting technicians have at their disposal and the equipment that is available.
So what is spray painting?
Spray painting is a painting technique that uses a device to spray the paint onto a substrate or material. Technicians use pieces of equipment called airbrushes – these are handheld instead of the traditional brush and pot.
Different Types of Spray Painting
There are many types of spray painting techniques available. These paint spraying techniques include air gun spraying, HVLP (High Volume Low Pressure), LVLP (Low Volume Low Pressure), Electrostatic Spray Painting and Spray Booths.
Air Gun Spraying
Air gun spray painting is used when the paint is used through an air powered spraying gun. The gun is built using a number of parts that include a nozzle, the paint storage basin and an adjustable air compression unit. The user pulls on the trigger, the paint then gets incorporated with the compressed air and is released in a fine, coating spray.
HVLP (High Volume Low Pressure)
This spray painting technique is very similar to the traditional air gun spraying we discussed above.
However, the gun itself must be used at a low pressure – LP. Despite the low pressure, there must be a higher volume of air available to enable the paint to be sprayed across the material.
LVLP (Low Volume Low Pressure)
These spray painting guns are very similar to the HVLP ones. However, they also use a low pressure and low volume of air when spray painting.
Electrostatic Spray Painting
Electrostatic spraying or powder coatings use atomized particles that are electronically charged when they leave the spray gun nozzle. The electrical charge enables them to spread evenly when used. This form of spray painting is frequently used for on site spraying – when an even spray is required.
Spray painting is also a popular touch when commercial businesses are having their buildings cladding repairs carried out. There is nothing worse than having a punctured metal sheet repaired that doesn’t match the rest of the building.
Now these are closed environments. These are most frequently used for car body repair shops. Now to guarantee the working conditions such as temperature, air flow and humidity, these sealed environments are equipped with some serious ventilation.
The ventilation available inside these sealed spray booths helps with the removal of the over sprayed paint from the air.
