Accepted Answer

Clear any loose mortar, debris or vegetation from the top course of masonry. The surface should be clean, reasonably flat and damp but not wet. If the existing masonry is very dry and absorbent, dampen it down about fifteen minutes before you begin. Dry masonry pulls moisture out of fresh mortar too quickly, which weakens the bond.
