WITHOUT DAMAGING SURROUNDING MATERIAL, DO THE FOLLOWING:

A. CUT OR GRIND OFF ITEM APPROXIMATELY 3/4 INCH (20 MM) BENEATH SURFACE AND CORE DRILL A RECESS OF SAME DEPTH

IN SURROUNDING MASONRY AS CLOSE AROUND ITEM AS PRACTICAL.

B. IMMEDIATELY PAINT EXPOSED END OF ITEM WITH TWO COATS OF ANTIRUST COATING, FOLLOWING COATING

MANUFACTURER'S WRITTEN INSTRUCTIONS AND WITHOUT EXCEEDING MANUFACTURER'S RECOMMENDED DRY FILM

OF EXISTING BRICK. IF CUTTING IS REQUIRED, USE A MOTOR-DRIVEN SAW DESIGNED TO CUT MASONRY WITH CLEAN, SHARP,

UNCHIPPED EDGES.

G. LAY REPLACEMENT BRICK WITH COMPLETELY FILLED BED, HEAD, AND COLLAR JOINTS. BUTTER ENDS WITH SUFFICIENT MORTAR TO

FILL HEAD JOINTS AND SHOVE INTO PLACE. WET CLAY BRICKS THAT HAVE ASTM C 67 INITIAL RATES OF ABSORPTION (SUCTION) OF

MORE THAN 30 GRAMS PER 30 SQ. IN. PER MINUTE. USE WETTING METHODS THAT ENSURE UNITS ARE NEARLY SATURATED BUT

SURFACE DRY WHEN LAID. MAINTAIN JOINT WIDTH FOR REPLACEMENT UNITS TO MATCH EXITING UNITS.

H. TOOL EXPOSED MORTAR JOINTS IN REPAIRED AREAS TO MATCH JOINTS OF SURROUNDING EXISTING BRICKWORK.

3.05 BRICK CONSOLIDATION TREATMENT

A. APPLY TREATMENT ACCORDING TO MANUFACTURER'S INSTRUCTIONS. APPLY TREATMENT AFTER REMOVAL OF EXISTING MORTAR BUT

PRIOR TO REPOINTING.

LOOSE DEBRIS.

2. DO NOT SPALL EDGES OF MASONRY UNITS OR WIDEN JOINTS. REPLACE ANY MASONRY UNITS WHICH BECOME DAMAGED.

3. CUT OUT OLD MORTAR BY HAND WITH CHISEL AND MALLET, UNLESS OTHERWISE INDICATED.

4. POWER-OPERATED ROTARY HAND SAWS AND GRINDERS WILL NOT BE PERMITTED UNLESS IT CAN BE DEMONSTRATED TO

ARCHITECT TO WORK SUCCESSFULLY WITHOUT DAMAGING CLAY MASONRY ON HORIZONTAL JOINTS ONLY. POWER-OPERATED

GRINDERS ON VERTICAL JOINTS ARE PROHIBITED.

C. JOINT POINTING: RINSE MASONRY JOINT SURFACES WITH WATER TO REMOVE ANY DUST AND MORTAR PARTICLES. TIME

APPLICATION OF RINSING SO THAT, AT TIME OF POINTING, EXCESS WATER HAS EVAPORATED OR RUN OFF AND JOINT SURFACES ARE

DAMP BUT FREE OF STANDING WATER.

1. APPLY FIRST LAYER OF POINTING MORTAR TO AREAS WHERE EXISTING MORTAR WAS REMOVED TO DEPTHS GREATER THAN

SURROUNDING AREAS. APPLY IN LAYERS NOT GREATER THAN 3/8 INCH (9.5MM) UNTIL A UNIFORM DEPTH IS FORMED. COMPACT

EACH LAYER THOROUGHLY AND ALLOW TO BECOME THUMBPRINT-HARD BEFORE APPLYING NEXT LAYER.

2. TAKE CARE NOT TO SPREAD MORTAR OVER EDGES ONTO EXPOSED MASONRY SURFACES, OR TO FEATHEREDGE MORTAR.

3. WHEN MORTAR IS THUMBPRINT-HARD, TOOL JOINTS TO MATCH APPROVED SAMPLE. REMOVE EXCESS MORTAR FROM EDGE OF

JOINT BY BRUSHING.

4. CURE MORTAR BY MAINTAINING IN A DAMP CONDITION FOR NOT LESS THAN 72 HOURS.

5. WHERE REPOINTING WORK PRECEDES CLEANING OF EXISTING MASONRY, ALLOW MORTAR TO HARDEN NOT LESS THAN 30 DAYS

BEFORE BEGINNING CLEANING WORK.

6. CURE HYDRAULIC LIME MORTAR ACCORDING TO MANUFACTURER’S REQUIREMENTS. NEW LIME POINTING MORTAR WILL NEED TO

BE DAMPENED REGULARLY WITH THE FOLLOWING CURING METHODS:

E. ACCEPTABLE CURING METHODS INCLUDE COVERING WITH WET BURLAP AND POLYETHYLENE SHEETED PANELS, PERIODIC HAND

MISTING, AND PERIODIC MIST SPRAYING USING SYSTEM OF PIPES, MIST HEADS, AND TIMERS.

F. ADJUST CURING METHODS TO ENSURE THAT POINTING MORTAR IS DAMP THROUGHOUT ITS DEPTH WITHOUT ERODING SURFACE

MORTAR.

7. FOR HYDRAULIC LIMES, RETENTION OF MOISTURE WITHIN THE MORTAR FOR THE FIRST SEVERAL DAYS [MINIMUM OF 96 HOURS] IS

CRITICAL TO ENSURE THAT THE HYDRAULIC SET TAKES PLACE BECAUSE ITS HYDRAULIC CONSTITUENTS REACT WITH WATER

ITSELF. THEREAFTER, THE REMAINING CARBONATION SET REQUIRES CYCLICAL LIGHT DAMPING AND SLOW DRYING. FOLLOW

MANUFACTURER’S INSTRUCTIONS REGARDING THE TREATMENT OF THE MORTAR JOINTS THROUGHOUT THE DURATION OF THE

CURING PROCESS.

8. HAIRLINE CRACKING WITHIN MORTAR OR MORTAR SEPARATION AT EDGE OF A JOINT IS UNACCEPTABLE. COMPLETELY REMOVE

AREAS. (ASSUME 100 LINEAR FEET OF REPAIR)

B. FACADE CRACKS: AS FOLLOWS, UNLESS OTHERWISE INDICATED.

CRACK SIZE (WIDTH)

PROCEDURE

D. REPLACE ENTIRE AREAS OF SEALANT WHERE INDICATED ON DRAWINGS.

3.09 MISCELLANEOUS WORK

A. PAINTING STEEL UNCOVERED DURING THE WORK, INSPECT STEEL EXPOSED DURING MASONRY REMOVAL. WHERE ARCHITECT

DETERMINES THAT IT IS STRUCTURAL, OR FOR OTHER REASONS CANNOT BE TOTALLY REMOVED, PREPARE AND PAINT IT AS FOLLOWS:

1. REMOVE PAINT, RUST, AND OTHER CONTAMINANTS ACCORDING TO SSPC-SP 2, "HAND TOOL CLEANING" AS APPLICABLE TO MEET

PAINT MANUFACTURER'S RECOMMENDED PREPARATION.

2. IMMEDIATELY PAINT EXPOSED STEEL WITH TWO COATS OF ANTIRUST COATING, FOLLOWING COATING MANUFACTURER'S WRITTEN

INSTRUCTIONS AND WITHOUT EXCEEDING MANUFACTURER'S RECOMMENDED RATE OF APPLICATION (DRY FILM THICKNESS PER

COAT).

3. IF ON INSPECTION AND RUST REMOVAL, THE CROSS SECTION OF A STEEL MEMBER IS FOUND TO BE REDUCED FROM RUST BY

MORE THAN 1/8 INCH (3 MM) NOTIFY ARCHITECT BEFORE PROCEEDING.

INCLUDING CORNERS, MOLDINGS, AND INTERSTICES, AND THAT PRODUCES AN EVEN EFFECT WITHOUT STREAKING OR

DAMAGING MASONRY SURFACES. KEEP WALL WET BELOW AREA BEING CLEANED TO PREVENT STREAKING FROM RUNOFF.

F. PERFORM ADDITIONAL GENERAL CLEANING, PAINT AND STAIN REMOVAL, AND SPOT CLEANING OF SMALL AREAS THAT ARE

NOTICEABLY DIFFERENT WHEN VIEWED ACCORDING TO THE "CLEANING APPEARANCE STANDARD" PARAGRAPH IN THE

QUALITY ASSURANCE ARTICLE, SO THAT CLEANED SURFACES BLEND SMOOTHLY INTO SURROUNDING AREAS.

WATER IN HORIZONTAL BACK-AND-FORTH SWEEPING MOTION, OVERLAPPING PREVIOUS STROKES TO PRODUCE

UNIFORM COVERAGE.

H. CHEMICAL-CLEANER APPLICATION METHODS: APPLY CHEMICAL CLEANERS TO MASONRY SURFACES ACCORDING TO

CHEMICAL-CLEANER MANUFACTURER'S WRITTEN INSTRUCTIONS; USE BRUSH OR SPRAY APPLICATION. DO NOT SPRAY APPLY

AT PRESSURES EXCEEDING 50 PSI. DO NOT ALLOW CHEMICALS TO REMAIN ON SURFACE FOR PERIODS LONGER THAN

THOSE INDICATED OR RECOMMENDED IN WRITING BY MANUFACTURER.

I. RINSE OFF CHEMICAL RESIDUE AND SOIL BY WORKING UPWARD FROM BOTTOM TO TOP OF EACH TREATED AREA AT EACH

STAGE OR SCAFFOLD SETTING. PERIODICALLY DURING EACH RINSE, TEST PH OF RINSE WATER RUNNING OFF OF CLEANED

AREA TO DETERMINE THAT CHEMICAL CLEANER IS COMPLETELY REMOVED.

1. APPLY NEUTRALIZING AGENT AND REPEAT RINSE IF NECESSARY TO PRODUCE TESTED PH OF BETWEEN 6.7 AND 7.5.
