1. FOR POINTING MORTAR, PROVIDE SAND WITH ROUNDED EDGES. WITHOUT DAMAGING CLAY MASONRY ON HORIZONTAL JOINTS ONLY. POWER-OPERATED GRINDERS ON VERTICAL JOINTS ARE PROHIBITED.
2. MATCH SIZE, TEXTURE AND GRADATION OF EXISTING MORTAR AGGREGATE AS CLOSELY AS POSSIBLE. C. JOINT POINTING: RINSE MASONRY JOINT SURFACES WITH WATER TO REMOVE ANY DUST AND MORTAR PARTICLES. TIME APPLICATION OF RINSING SO THAT, AT TIME
E. WATER: CLEAN, FREE OF OILS, ACIDS, ALKALINE AND ORGANIC MATTER. OF POINTING, EXCESS WATER HAS EVAPORATED OR RUN OFF AND JOINT SURFACES ARE DAMP BUT FREE OF STANDING WATER.
