Clean masonry surfaces only when air temperatures are above 40 degrees F (4 deg. C) and will remain so until masonry has dried out, but for not less than seven days after completion. 2. Do not re-point mortar joints unless air temperatures are between 40 degrees Fahrenheit (10 deg. C) and 80 degrees Fahrenheit (27deg. C) and will remain so for at least 48 hours after completion of work. 3. Remove any loose, crumbling mortar and rake back to uniform depth 2 to 2 1/2 times the joints width. Joints may be farther if necessary to reach mortar sound enough to serve as a base for repair. Take care to avoid damaging existing granite stone. Do not enlarge width of the joints. The only equipment allowed to rake the joints shall be a hammer and chisel with a blade about half the width of the joint. A pin grinder with a tuck-pointing blade, or an approved equal, may be used with approval from the Director of Public Buildings or his/her representative. 4. After removing the old mortar, clear the bedding surface of dust and debris, then spray it with water. The area to be re-pointed should be moist but surface dry when the new mortar is placed. 5. Measure mortar materials in boxes, or by other approved units. Use machine batch mixer, except that where small quantities are required, mixing may be done by hand. Mixer shall be subject to approval by the Engineer. Time of mixing shall be not less than five minutes after all materials are in the mixer. Mix only enough mortar at one time to supply immediate requirements of the manufacturer. 6. Use mortar within two hours of mixing. If necessary, re-temper mortar within two hours of mixing to replace water lost by evaporation. 7. Place the pointed mortar in layers about one-third (1/3) inch deep, using a narrow pointing trowel. Pack each layer firmly, then allow it to reach thumbprint hardness before placing the next layer. Do not tool each layer smooth; leave surface rough to help the bond of subsequent layers. Compress the final packing as much as possible to completely fill the joint. Compact joints solidly before final tooling. Tool joints to match existing work. Take care not to spread mortar over edges of brick onto exposed surfaces. remove excess mortar, smears and droppings as work progresses. Cure mortar by maintaining it in a damp condition for five days. Joints shall be tooled to form a grapevine beaded joint and shall match as closely as possible the existing joint. 8. Where repointing work precedes cleaning of existing stone, allow mortar to harden not less than 30 days before beginning cleaning work. 9. Remove any unnecessary object that is not currently being used, including attachments for wiring, piping, etc. 10. The Contractor shall check all mortar joints and shall repair open or deteriorated joints by cutting to a depth of 3/8" or to sound mortar and re-point them with mortar of the same color as existing mortar. ---PAGE BREAK--- 10-8 10.23 GRANITE STEPS REHABILTATION A.
