Manny, I used an electric paint sprayer quite a few years ago and the results were awful, they don’t use air to atomise the liquid they just force it through a small orifice, the result is that the paint splatters everywhere and it just runs as it’s difficult to control how much paint goes on. If using a normal air driven spray gun is not an option then I would recommend using aerosol cans, they can give an excellent finish with a little practice. There are many different suppliers of aerosols with a multitude of different paints I am sure there are some that will suit your needs. I have a compressor and spray gun but by choice I use aerosols.

Like Dave W I didn't find an electric paint sprayer did a very good job, exceedingly wasteful of paint and made a mess everywhere, but that was spraying emulsion paint 45 years ago, no doubt they are improved these days.

It depends on what you want to do.

10 years ago I used an Oldfields electric sprayer to paint the outside of my house with water based (acrylic) paint which did an excelent job. This was their best model (not cheap) and uses a small, built in piston pump to atomise the paint. Much quicker than using a brush or roller. Recently I had to paint a wooden fence and the old sprayer did not work so bought one of the new cheaper sprayers. This one used a built in fan to atomise the paint (like the sprayers that used to come with a vacuum cleaner). It did not produce a fine mist but did an excelent job of painting a rough sawn timber fence with acrylic paint.

I would not use an electric sprayer for applying car quality paint and lacquers and use an air compressor spray gun instead.

Paul.

My experience of this type of spray gun is that they are adequate, bordering on suitable for coating sheds and fences with preservative, but you will be very very lucky to get even a reasonable paint finish. Some years ago a friend of mine attempted to spray a white car with a gun of this type. The result was a car that looked like it had been coated in rice pudding !!

Depends on the spray gun, I have used one with good success, still have it and it was made by Wagner has a carbide pump and the pressure is high with very good atomisation. Mine is around 50 years old and the others available the time were Burgess which were by comparison pretty hopeless !

I have sprayed bike tanks, frame's, cars [cellulose] & walls [emulsion paint] all successful but how the modern units are by comparison I have no idea. The one big difference was the spray pattern is round only unlike air powered guns which can be either round or fan pattern.

What are you actually spraying? I have done a bit of spraying so may be able to point you in the right direction.

Manny, like JohnF I've had good/excellent results with quality electric spray systems. You need to look at HVLP units. I started with an Apollo 400 many years ago and now use a Fuji machine for every finish, including cellulose on cars and two pack with "disposable" sprayguns. Just find a cheap gun that fits your system if spraying two pack. Last job was an MGB GT in mid blue, no problems, no "spatter" no runs. Just take your time to learn before using in anger!! Avoid,at all costs, the solenoid operated guns like the " Burgess" and it's modern equivalents. N.

Hi,

thanks for the input.

Answer to question; Barrie Lever.

I would like to spray Enamel paint on home made machine accessories such as Ball turner, custom made brackets for mill, etc

I would also like to lacquer brass Gyroscopes .

Thanks Nathan and John, I will look out for the HVLP unit.

Many moons ago I sprayed a Morris Minor with a spray gun connected to a vacuum cleaner, it did a half reasonable job, a bit orange peel here and there but stand back 10 feet and it looked quite presentable.

For small items a desktop compressor and airbrush might be a practical option. We paid just over £70 for one with a tank and a pair of cheap (but perfectly usable) airbrushes which has worked well for painting a 16mm scale loco.

Manny, I believe a small air brush kit would be capable of spraying the parts mentioned.

Dare I say it - use an airbrush on a "silent" compressor but buy a Badger.

100% you are into airbrush territory with the work you are proposing.

I always use Badger airbrushes for my models and similar size spray jobs.

If I was only allowed one airbrush or spray gun then it would have to be a Badger 250, they are very primitive but also very effective, these will spray quite small objects, lets say a golf ball and will easily handle something like a 48" span model aircraft.

I will just quickly describe each of the Badger airbrushes.

250 is a single action external mix airbrush, with two different size jars.

350 is a single action external mix, with 3 different options on the spray head size, I don't use these much now.

200 is a single action internal mix airbrush, these cannot quite get to the biggest spray pattern of the 250 but are way more controllable in small spray patterns, these need slightly thinner paints to work. This airbrush atomises the paint better than either the 250 or 350.

150 is a dual action internal mix airbrush, paint flow is controlled by pulling the trigger back, air flow is controlled by pressing the trigger, this airbrush is basically the 200 with the addition of the trigger paint control.

None of the airbrushes described above are greedy on air and generally work well on a 30psi pressure when the trigger is depressed.

I use a Badger compressor which I bought second hand on Ebay, I buy all of the airbrushes on Ebay and they are almost always unused, so in perfect condition. I also have Jun-Air silent compressor but I lend that to a friend who builds models with me.

Using an electric spray gun on your projects would be like using a chainsaw to cut up balsa wood for a small rubber powered model aeroplane !!
