Re: painting pressure

[mark krawczuk]

hi,      you can get  high volume , low pressure  which operates at 10 psi at the gun ( you call them hvlp  spray guns).  and you can also get  compliant or  hte  (which stands for high transfer efficiency) spray guns. such as the  sata RP (reduced pressure) or the devillbis gti . these  two operate  at 2 bar  or 29 psi.       the compliant  (hte) guns give a better finish as far as i`m concernd. the hlvp  can tend  to  give a more orange peeled finished. to make use of these guns , you really should really have large diameter  air hose and a large compressor.     however if your talking about using a normal standard  spraygun, and spray at a  too higher pressure ( greater than about  55 to 60 psi)   you will have  alot of over spray and dry spray, and loss of shine and sandy textured finish.     at a too low pressure you will get   heavy orange peel and runs, but a great shine!!!.   with a normal spray gun i personally use about 40 to 50 psi depending on  weather temperature .        mark k       ----- Original Message ----- From: Ben C To: [EMAIL PROTECTED] Sent: Tuesday, September 10, 2002 9:15 AM Subject: painting pressure what are the pro's and cons of   high pressure when painting top coat   low pressure when painting top coat   ??   cheers ben --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
