Use a flat pointed trowel to apply a 2-3" layer of mortar to the wire frame.  Build the rock from the bottom up.     Make a layer of mortar around the base of the rock and work upwards around the wire frame. Create a realistic looking rock by adding contours and patterns to the surface of the mortar.  Use your trowel to create dips and creases in the surface of the mortar. Press a real rock into the mortar to make imprints of the rock's texture. Press a sea sponge or scouring pad into the rock to create pock marked look. Wrap a plastic bag around your hand and press it into the mortar to give a wrinkled look. The curing process is a result of a chemical reaction, not the cement drying out. Although 75% of the curing is completed after one week, it may take up to a month for cement to cure completely.  Mist the surface of the rock every few days as it cures. Keep the cement out of direct sunlight to prevent cracks. Cover the rock with plastic sheeting as it cures.
