cwarrior 14 Report post Posted May 18, 2011 Hey guys, looking for a pump to spray large areas of concrete for rust removal. Currently use pump up sprayer, but takes too long. How many gpm and psi should I get? Shurflo, Delevan? Also, anyone know where I can purchase a portable spray system? Thanks, Mark Share this post Link to post Share on other sites
