Hey guys, I finished my first job and I had one constant issue. While cleaning the edges of concrete where my surface cleaner can’t reach I noticed that the pressure was too much. Mulch and loose dirt was getting blasted away by the pressure coming off my wand. I tried cleaning from different angles, different heights and using different tips (started with a turbo nozzle, then tried jrod, and finally yellow tip.) I’m guessing that the 4200 default psi is too much. What would you guys recommend for concrete cleaning?
Well most of the time you could ball valve it if you have a shutoff before your gun which I am hoping you do it also can make rinsing stuff that was splattered onto a wall or siding easier to clean up too. But knowing your machine and unloader settings and matching tips to it over time is part of the initial setup. I run my psi much lower to fit for my surface cleaner to do what it needs to and work around those settings for psi on the wand personally so unless you are working with commercial concrete on a consistent basis you should probably consider that into your normal pressure setup and tips.
