Vertical Stamping - RockMolds
STEP 8. After the vertical stamp mix has sufficiently firmed up, usually within 4-6 hours, the joints can be accented by carving out. A Rockmolds tuck point trowel works great. Tip: Keep the joints tight between the stones, to create a shadow and depth. Tip: A chip brush dipped in water may be used at this time as well to clean up the stones.
