gavin.starr Posted May 3, 2009 Share Posted May 3, 2009 just after a bit of advice from the main spray painters ive decided to sack off using aerosol cans now as they cost too much. im looking at buying a compressor but was wondering what is the best volume to go for. i dont do anything major but i would like to do some larger projects and would just like to see what people would recoment i get before i go and buy the completley wrong thing. thanks gav Quote Link to comment Share on other sites More sharing options...
Jay_vr6 Posted May 3, 2009 Share Posted May 3, 2009 also interested in this, the amount of rattle cans I've been through would buy me a bloody spraybooth Quote Link to comment Share on other sites More sharing options...
Kranz Posted May 3, 2009 Share Posted May 3, 2009 To be semi serious about using air tools etc you'll need something like a semi-decent belt driven 2 to 3hp one with about 100 litre tank and that can supply 9cfm and upwards. Most air tools take a lot of air. This looks ok http://cgi.ebay.co.uk/Quality-AIR-COMPRESSOR-Workshop-9-CFM-Belt-Driven_W0QQitemZ110283806276QQcmdZViewItemQQptZUK_Air_Tools_and_Compressors?hash=item110283806276&_trksid=p3286.c0.m14&_trkparms=72%3A1688%7C66%3A4%7C65%3A12%7C39%3A1%7C240%3A1318%7C301%3A0%7C293%3A1%7C294%3A200 If its JUST going to be for a little touch up spraying then you could go smaller..... but a lot of high quality touch up spray guns still need a decent volume of air, something like 4 to 5 CFM at 40psi. A small compressor will struggle to produce this and even one with a decent sized tank will have you stopping to allow it to build up pressure again. This looks ok for just touch up spraying http://cgi.ebay.co.uk/Rand-Air-Compressor_W0QQitemZ330325423307QQcmdZViewItemQQptZUK_Air_Tools_and_Compressors?hash=item330325423307&_trksid=p3286.c0.m14&_trkparms=72%3A1688%7C66%3A4%7C65%3A12%7C39%3A1%7C240%3A1318%7C301%3A0%7C293%3A1%7C294%3A200 Quote Link to comment Share on other sites More sharing options...
Jay_vr6 Posted May 3, 2009 Share Posted May 3, 2009 blimey i was told 200 litre tank minimum when i looked in to this once before, that was for doing side skirts etc Quote Link to comment Share on other sites More sharing options...
gavin.starr Posted May 3, 2009 Author Share Posted May 3, 2009 i wass looking sat something more like this http://cgi.ebay.co.uk/50LTR-2HP-ELECTRIC-AIR-COMPRESSOR-BRAND-NEW-BOXED_W0QQitemZ370188400809QQcmdZViewItemQQptZUK_Air_Tools_and_Compressors?hash=item370188400809&_trksid=p3286.c0.m14&_trkparms=72%3A1689%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318%7C301%3A0%7C293%3A2%7C294%3A50 do you think that it would be ok for doing the random odd jobs or is the hp a bit low, im not after going into it propperly just a bit of fun really to expand away from aerosol cans.

merckx Posted May 3, 2009 Share Posted May 3, 2009 I've got a 50 litre 2hp airmaster compressor which does the job, not really suitable for spraying a full car in one go but fine for spraying individual panels. The actual flow rate you can get is not always what the manufacturers specify. Quote Link to comment Share on other sites More sharing options...
jacko Posted May 3, 2009 Share Posted May 3, 2009 Im not really sure about exactly what size is needed, because the one we've got at work is a massive vane compressor. But you need a pretty big tank to use any sort of air tools/ spray gun, the other little one we've got at work (£100 from netto jobbie) just isnt up to the task. Oh and dont forget about a regulator Also something to take into account is chances are you will be wanting to use 2k paints as you need them to air dry, so you have to start thinking about masks as well Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted May 3, 2009 Share Posted May 3, 2009 I have a 2HP 50lt that puts out about 6cfm, and i have sprayed a couple of a mates truck cabs with it, no problem, does require the occasional wait, but its only a couple of mins.

TurboBrett Posted May 3, 2009 Share Posted May 3, 2009 i use a 2hp 48L compressor and tank, its not enough to blow over a full car but for what i use it does the job great, certainly be enough for bumpers/ skirts Quote Link to comment Share on other sites More sharing options...
Jay_vr6 Posted May 3, 2009 Share Posted May 3, 2009 now is 2k paint not going be banned shortly ? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted May 3, 2009 Share Posted May 3, 2009 now is 2k paint not going be banned shortly ? Not heard anything about this? even though the majority of body shops are using water based base colours, you still need 2K lacquer over it, or it runs off first sign of rain;) Quote Link to comment Share on other sites More sharing options...

If you plan on spraying 2k please get a good airfed mask as this stuff is not very good for you. You will need quite a big compressor to run a gun and mask.

Isnt it true that you cant spray a whole car in solvent, but you can spray parts of a car? And ye definately need a mask as well, i think our work one was around £170, and then you need a gun........ the list goes on lol Quote Link to comment Share on other sites More sharing options...
SUPRALOOPY Posted May 4, 2009 Share Posted May 4, 2009 Isnt it true that you cant spray a whole car in solvent, but you can spray parts of a car? No:blink: You can spray the whole car if you have the paint, Its a stupid european law on emissions that is making solvent based paint get phased out. If you can still get it (still easy to get) then you can use it. Its really only aimed at big bodyshops that use more than x amount of solvent products.

Tricky-Ricky Posted May 4, 2009 Share Posted May 4, 2009 Its a fallacy that all 2K paints are isocyanate based, quite a few are not, and for hobby use, i would and do just use a good quality mask, defiantly use air Fed if you are going to spray on a daily basis, but otherwise you are not going to get poisoned doing small jobs. Isocyanate's are accumulative, and build up gradually over a long exposure period, i know people in the trade who don't even use a mask for touch ups etc, and they have been doing it for 15 years, and are still healthy.

And after about 25 years in the game they die:p I know of two sprayers who had this attitude and nearlly made retirement. Its up to you but I always wear a mask, Sometimes when spraying basecoat I don't and spend the rest of the evening making whatever colour I have been using Bogies:D Quote Link to comment Share on other sites More sharing options...

Get some paint from your supplier on the cheap, usually mixed for customers, stuff like that...and just play till you get a good finish. EDIT : Get yourself a nice decent gun as well Quote Link to comment Share on other sites More sharing options...
