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.

A. REPLACEMENT OF DETERIORATED MORTAR JOINTS, CRACKED MORTAR JOINTS, MISSING MORTAR JOINTS, AND JOINTS NOT BONDED
TO FACE BRICK, ADJACENT STONE.
B. JOINT RAKING: RAKE OUT MORTAR FROM JOINTS TO DEPTHS EQUAL TO 2-1/2 TIMES THEIR WIDTHS BUT NOT LESS THAN 1/2 INCH
(12MM) NOR LESS THAN THAT REQUIRED TO EXPOSE SOUND, UN-WEATHERED MORTAR.
1. REMOVE MORTAR FROM MASONRY SURFACES WITHIN RAKED-OUT JOINTS TO PROVIDE REVEALS WITH SQUARE BACKS AND EDGES
AND TO EXPOSE MASONRY FOR CONTACT WITH POINTING MORTAR. BRUSH, VACUUM, OR FINISH JOINTS TO REMOVE DIRT AND
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
