SYSTEM 3: FERROUS METAL PIPE AND SUPPORT, INCLUDING STEEL, CAST IRON, AND DUCTILE

IRON (EXPOSED INDOORS AND OUTDOORS) (CONTINUED)

SYSTEM 6: CONCRETE COATING (IMMERSION, SEVERE CONDITIONS SUBJECT TO HYDROGEN SULFIDE

EXPOSURE) NOTES (CONTINUED):

3. SURFACE PREPARATION

3.1. VERIFY STATE OF CURED CONCRETE. NO CONCRETE SURFACE SHALL BE COATED WITHOUT A MINIMUM

28-DAY CURE OR VERIFY THE CONCRETE EMITS LESS THAN 3 LB. PER 1,000 SQ./FT. IN A 24-HOUR PERIOD VIA

A CALCIUM CHLORIDE TEST OR ASTM D4263 PLASTIC MAT TEST. THIS APPLIES TO PATCHED AREAS, NEW POUR

AREAS, OR NEWLY FORMED WALLS AND CONTAINMENT DIKES.

3.2. ROUGHEN CONCRETE SURFACE FOR IMPROVED ADHESION. CONCRETE SHALL BE ABRADED BY AN APPROVED

METHOD FROM SP13 SUCH AS ABRASIVE BLASTING, HIGH PRESSURE WATER BLAST, WATER JETTING WITH

ABRASIVE INJECTION, OR SIMILAR TO ACHIEVE AN ICRI STANDARD CSP3-5 PROFILE OVER THE ENTIRE

SUBSTRATE TO BE COATED.

3.3. REMOVE SURFACE CONTAMINANTS. REMOVE ALL OILS, GREASE, DIRT, EFFLORESCENCE, LAITANCE OR OTHER

FOREIGN CONTAMINANTS. THE CONCRETE SURFACE WILL ALSO NEED TO BE FREE OF MOISTURE OR STANDING

WATER. WASH DOWN WITH CLEAN WATER AND VACUUM THE SURFACE SUBSEQUENT TO THE ABOVE

PROCEDURES.

3.4. REPAIR SUBSTRATE DEFECTS. AFTER THE CONCRETE IS CLEAN AND DRIED, ALL SURFACE IRREGULARITIES ARE

TO BE REPAIRED WITH THE SPECIFIED SURFACE FILLER. THIS INCLUDES FORM VOIDS, HONEYCOMBS, FINS, CRACKS, SPALLED AREAS, AND CONTROL JOINTS. ALL METALLIC PROTRUSIONS SHALL BE GROUND BELOW THE

SURFACE AND THEN PATCHED OR FILLED WITH AN APPROVED MATERIAL. FILL ANY DISCONTINUITIES, SUCH AS

PICKING HOLES, FLUSH WITH THE ADJOINING CONCRETE SURFACE.
