Hi there.
So when i buy my rig im considering maybe a 5000psi, 8+GPM rig. At what point is the pressure not enough to remove things like paint from brick, graffiti, etc? The only experience i have with a pressure washer was with a 2600 PSI(not sure of the GPM) cold water stand alone unit. It really got rid of alot of nasty stuff from flatwork like my driveway and sidewalk. But when does just pressure alone become ineffective by itself?
I forgot to include im mostly talking about a hot water unit 200F-220F.
