What are the different types of paint guns?
Low pressure electric paint gun
Doesn't cost a lot but it reaps some big rewards!
Low pressure paint station
To further develop, if the job consists of small renovations or you'e fascinated by the visual arts, this is the one you need to buy! This is the one with the ant-fog feature!
High pressure paint gun
There are different power ranges and available pressures, even several nozzles - according to the projected paint's viscosity - various tank capacities and some models even featre a flexible supply hose to better tackle those tricky pot corners!
Pure joy in the form of color for your walls or surfaces!
Pneumatic paint spray gun
Connected to an independent compressor, this paint gun is linked to a cup. When located above, it's referred to as a gravity gun, while when it is attached below, it's called a suction gun. The first option is linked to a low-pressure compressor and is limited in use - impossible to horizontally paint up high for example. It is much more suitable for low-height vertical or horizontal work. The second example, the suction gun, has the cup bucket attachment underneath it and is suitable for all other applications.
The compressor is unfortunately not supplied with the gun. There are of course various degrees of quality when it comes to paint guns! Usually implying very detailed work, it is often used for autobody work.
Paint gun: what paints can you apply?
The paint gun is used to apply paint on any given surface. It must be diluted to render it liquiduified (5 to 10%).
To avoid mistakes, let’s summarize the relevant vocabulary right away.
- Aqueous paint (vinyl or acrylic): This type is diluted with water.
- Solvent-based paints (glycerophthalic or polyurethane): This paint is diluted with a solvent - which is specified on the painting.
Electric and compressed air paint gun
How an electric paint gun functions
The electric paint gun contains a motor which actuates a piston, thereby projecting the paint onto the surface at a certain pressure, to de determined by the specific model.
The pressure is relative to the flow, which is determined by the model's power. The spray control technology limits the spray and applies a very thin, smooth layer of paint.
How a pneumatic paint gun functions
Paint gun: what is the spray effect?
As the name suggests, it is the fog that is created when applying paint.
Generally, fog residue seeps to all the unprotected surfaces.
To prevent this: good protection (tarpaulins, masking tape) and if if possible, opt for the HVLP electric gun which considerably reduces the fog effect.
No matter what the job, consider using a protective mask to protect your airways!
Paint gun: flow, pressure and power
These three elements are interconnected and have a direct impact on the possible paint that you will apply and how it will be applied.
Often adjustable, their role is to adapt your gun to the product you apply - paint, varnish, glosses etc.
Paint gun: what gun at what price?
The brand, power, options, capacity, hose length and additional accessories are all details that can make or break a decision.

Free-standing or attached cup? Watch out for the wrist and the maneuverability!
Tank or cup capacity . Since you have to put it with it, it's a big factor!
Length of pipe: not to overlook if repainting the house's gables!
Area covered in 1 minute.
Anti-fog system or easy dilution.
If compressed air, the cup's position and the quality of the nozzle (or needle). Which must be in an abrasive resistant alloy.
The frequency of use will determine the ideal budget.
The nozzles must be adapted to the type of product you will apply.

With a handyman-father, I grew up with the soft sound of the sander and hammer on weekends.
I am both manual and cerebral (yes, it is possible.), I learned the basics of DIY and the customization of furniture because I was passionate. The salvage mentality is a true way of life that allowed me to know how to use all the tools and products needed to give something a second life, from sander to varnish.
I have two favorite activities: the transformation of old furniture and decoration tips. I am always ready to lend a helping hand to revamp a table or to restore a mirror that was intended for the trash that will become a friend’s centerpiece.
I’m convinced that it’s possible to reinvent an interior by small, regular modifications, I constantly research low-cost, test ideas.
