When the mortar is firm to the touch, brush diagonally across it to remove any dry mortar crumbs. (Brushing in line with the joints can pull out the fresh mortar.) Then carefully sponge mortar residue off the brick faces. For the next three days, use a tarp to protect the soft joints from the sun, wind, or hard rain, and give the wall a daily misting to keep the brick and mortar moist.
