to me it looks as if you could lift layers of this material if using high pressure? as the surface seems uneven will some of it not lift up?

Also any other tips if cleaning this?

Even when we Pressure wash we very rarely use the full high pressure as it causes damage even more so on Indian Sandstone.

Give me a call and i may be able to help
