I have a Power Washing job tomorrow and was wondering how much pressure was best to use to power wash a cement patio and sidewalk. Is a low pressure machine safer/better? It’s an add on to a window cleaning job we are doing tomorrow at the customers request. We don’t usually do PW.
It all depends on what your trying to wash off, Are you using a surface cleaner? If not just vary the height of the wash tip to the cement closer higher pressure, further away lower pressure. try different tips also. Good luck
Go low pressure Bob, you can damage the surface of the cement with high pressure. Call me if you need a hand.
