Remove and replace masonry units that are loose, chipped, broken, stained or <br />otherwise damaged or that do not match the adjoining units. Install new units to <br />match adjoining units; install in fresh mortar, pointed to eliminate evidence of <br />replacement. <br />B. Pointing: During tooling of joints, enlarge voids and holes, except weep holes, and <br />completely fill with mortar. Point up joints, including corners, openings, and adjacent <br />construction, to provide a neat, uniform appearance. <br />C. In-Progress Cleaning: Clean unit masonry as work progresses by dry brushing to <br />remove mortar fins and smears before tooling joints. <br />D. Final Cleaning: After mortar is thoroughly set and cured, clean exposed masonry as <br />follows: <br />1. Remove large mortar particles by hand with wooden paddles and nonmetallic <br />scrape hoes or chisels. <br />2. Remove all mortar fins larger than 1/2 inch within cells to be reinforced. <br />END OF SECTION
