Hi all, as title says really, I know that I'd need a bigger compressor than I have currently. But what else do I need to paint? Really want to try spraying my mini myself.

Thanks, Alex

I had a 100ltr 3hp compressor originally but was luckily given a 200ltr 4hp compressor by my lad. 

 

Now i used the 100ltr unit for breathing air and the large compressor for my spray gun. Now as it went along the small compressor died so had to use the large for breathing and spraying. It worked well as it goes but i had triple filtration for the breathing air and an inline filter for the spray gun. All coming off a Y piece from the reservoir.

 

Also with this i had to extend the air intake for the compressor to outside away from any paint fumes.

 

Now i made my own extraction system with a directed exhaust which worked well. Heating, i used a couple of normally electric heaters to heat the garage up then turned off while painting.

 

I borrowed a forced air breathing mask which was a godsend and YOU DO need for 2K. (You get one set of lungs, look after them.)

 

I had two spray guns, one for primer and one for Topcoat. I use an Iwata Spray gun which for its price gave a really good finish.

 

DA sander as well.

Smart person one off the lads lost half a lung not wearing a mask air feed

That's great, thanks for all your advice! I'll be looking to start collecting bits to paint over Christmas time when I'm off work. To paint once the weather gets a bit better. I'll keep you posted

I recently sprayed my mini in cellulose using a 50 litre 3hp compressor and a devilbiss jga gun.
Compressor coped pretty well I thought, certainly wasn't running constantly.

Is the tank size or the HP more important?

[Daz1968]

The hp, or cfm is more important as once spraying tank empties pretty quickly, I have a 3hp Clarke with 100 litre receiver, I use a devilbiss sri pro spraygun with 1.2mm tip, I use disposable cup system so I have a larger cup for spraying.
I also have compressor in a different building with air piped in, drop legs to help remove moisture, a standard moisture removing regulator where I work, followed by a coalescing filter to remove oil mist. Then I have a cyclone type moisture remover at gun along with a small regulator. When I spray 2k I also have an airfed mask with its own carbon filter to allow clean breathing air.
My compressor just keeps up as the gun uses very little air, the mask keeps compressor running approx 50% of the time, so you need a good duty cycle on compressor. When painting epoxy I use a good filter mask so compressor has a much easier time then.
I built a frame inside the garage and used masking plastic to seal off the area along with incoming and outgoing booth filters, I use a large fan to blow clean air into the area and the positive pressure forces overspray to the outgoing filter. Worked pretty well for a diy set up, I also use a few heaters in the booth prior to painting, but remove them before I start. Another thing is you need very good lighting so I have strip lights I put on the wall to help.

There's a great guide on the MIG Welding Forum of all places, it details very well how to setup the best DIY setup.

A word of caution - watch out for isocyanates in your paint system choice and the required protective gear. They are nasty stuff. Just using an air respirator with the _correct_ filters is not enough.

I have a small old AID 50 litre compressor which I use for the spray gun, painted a MK2 jag shell (no doors, boot or bonnet as painted them separately)  with 2K and no problems with having enough air.  I then had a 150 litre clarke compressor located outside the workshop for the airfed mask.  I used two separate hoses cable tied together with one plugged into my mask (the correct one!) and the other into the spray gun.  It worked well if a little cumbersome.

Not an expert on this but, as far as I am aware you should NEVER breath air from a compressor UNLESS its designed to provide air fit for breathing. Found this link that covers some of the issues https://fix-my-compr...ir-compressors/
