redben101 Posted July 29, 2007 Share Posted July 29, 2007 I am in the process of spraying car parts in cellulose paint. My tools of choice is currently a 2.5hp compressor with a 25 litre air tank which does the job okay as it only needs to do a panel at a time. Because i am going to be doing a fair bit of spraying i am looking at getting a better gun, but then i read about HVLP compressors and guns. In your opinions is a decent gun and better compressor more use or would a HVLP system do better? Axminster have this Apollo Ap400 which seems good value but would it make a significant difference to my existing set up? Quote Link to comment Share on other sites More sharing options...
smo Posted July 29, 2007 Share Posted July 29, 2007 I use a mini HVLP gun on my standard compressor, its a 2.5hp twin with 50l tank and does the job nicely (shame my technique is carp) - i dont know how this would compare to a dedicated setup but i do know axminster tools are normally of excellent quality.

landmannnn Posted July 30, 2007 Share Posted July 30, 2007 I have got a similar low pressure type which i have had for ages. Can't speak for the Apollo one but mine is fine for spraying thin paints, I found cellulose difficult because it had to be thinned to much. I get much better results with a "proper" compressor.

Hi Ben, I asked these pertinant questions last year to a few people in the trade when planning the painting of my 90. The general feeling from the paint shop was that cellulose is going to be fazed out (sooner rather than later) and the HVLP (High Volume Low Pressure) guns wasted less paint and less overspray. I haven't got round to painting yet but intend to use an HVLP gun with water based paint (future proofing!). Open to advice from others!

Les Henson Posted July 31, 2007 Share Posted July 31, 2007 The phasing out of Cellulose-based paints has been suspended indefinitely (it was supposed to be the end of last year). I used a cheapo 'touch up' gun to paint the panels on catflap and it's worked well - £30 from Machine Mart. There are much better guns on the market - Devilbiss being one of the best, but if this is likely to be a one-off job, then spending a forune on a gun is a waste of money. Takes a bit of practice though Les. Quote Link to comment Share on other sites More sharing options...
redben101 Posted August 1, 2007 Author Share Posted August 1, 2007 thanks for the info. think i might stick with what i have for the moment. is water based paint sprayed on and then a laquer applied? Quote Link to comment Share on other sites More sharing options...
Les Henson Posted August 2, 2007 Share Posted August 2, 2007 Yes it is, but water-based paint is very expensive. Les. Quote Link to comment Share on other sites More sharing options...

redben101 Posted August 2, 2007 Author Share Posted August 2, 2007 i read on a volkswagen site that you need a steady room temperature of 21-25 degrees Quote Link to comment Share on other sites More sharing options...
keithjh Posted August 2, 2007 Share Posted August 2, 2007 I only spray cellulose. no two pack stuff here, Devilbiss suction feed cant remember the model but been using it for 30 years, compressor is a SIP 150 litre tank, 14CFM runs everthing i have. Really glad that the ban on cellulose has been lifted, as i hate two pack with a vengeance. regards Keith Quote Link to comment Share on other sites More sharing options...
smo Posted August 2, 2007 Share Posted August 2, 2007 Daft question but does metallic come in cellulose as i can only find places selling 2 pack metallic? Quote Link to comment Share on other sites More sharing options...
redben101 Posted August 2, 2007 Author Share Posted August 2, 2007 yes you can get metallic paints in cellulose, i may be wrong but Les sprayed his in metallic paint. Quote Link to comment Share on other sites More sharing options...
gruntus Posted August 3, 2007 Share Posted August 3, 2007 Yes it is, but water-based paint is very expensive.Les. Hi Les, How much more expensive on a litre to litre comparison? Regards Grant Quote Link to comment Share on other sites More sharing options...
Les Henson Posted August 4, 2007 Share Posted August 4, 2007 Water-based paint is more than three times the price of cellulose paints, so it would cost you several arms and legs to spray a whole vehicle. You can get cellulose paint in base paint, which dries to a matt finish and is the colour, then clear laquer on top of that. I buy it with laquer already added, so just the one coat is needed. Seperate laquer is better as it protects the base colour more. The problem with metallic paint is that any runs that have to be sanded out turn dark grey, so you would have to overspray again to restore the colour, so care has to be taken. Water based paints are easily damaged by bird droppings, some cars have had to resprayed due to this. Les. Quote Link to comment Share on other sites More sharing options...
