Can anyone tell me what kind of pressure I will need to remove oil based paint from patio concrete?

I may need to purchase a washer but don't want to pay for more pressure than I need.

(You know, the pressure is money, how much pressure do you want!)

The price difference between 2700# and 3700# is huge...I realize I may only need 3100# but right now I don't
have a clue what I need.

Rentals in my area are $180/day so I may as well purchase if I can get away with 3100# range for around $400.

Any experiences would help me decide on a course of action.

Thanks, Rafter

There's always the risk of not being able to remove all of the paint or cutting the surface of the concrete. Do you intend to leave it raw, paint it again or bond pavers etc to it?

I wouldn't try it with anything less than a 3,500 psi unit that uses a lot of water. If you go less than that I think you'll find yourself frustrated and using a jet tip rather than a fan tip and have a greater risk of cutting the concrete surface. I purchased a 2,700 PSI unit years ago and it was nothing but a disappointment for anything other than washing the cars.

I'm in Dayton.

ETA: I'm having my patio enclosed and hope to get the concrete back to a state where
I can stain it. (Actually, so the misses can stain it. I don't paint!)

There is a company in London, Oh (west of Columbus) that sells nice used units that they recondition. Mostly commercial grade, I would suggest that you look into them before you make a purchase...Equipment Specialist Inc...1-800-262-1551. I bought a commercial grade pressure washer, 13hp Honda motor, 4200 psi Cat pump, reconditioned (hell it looks brand new) with hose and gun for under $800. They have way less expensive units, or way more expensive, and they service and warranty what they sell.
