My friend wanted to use postcrete over an old concrete path and over his old patio. I assumed he should have used normal cement but he didnt listen. Will they stay in place?
Should he have taken old patio stones up and removed old cement to hardcore then laid a new dryish layer of cement then new stones on this?
