«»
Run a stiff, dry, natural-bristle brush over the mortar in one direction, smoothing away the bumps and ridges left by the tuck-pointing trowel. Stay off the walk overnight. The mortar will fully harden in about a week. If the weather during that time is very hot, windy, or dry, keep the mortar moist with wet burlap.
