3.7 PAINT SURFACE PREPARATION

ALLOW NEW PAVEMENT SURFACES TO CURE FOR A PERIOD OF

NOT LESS THAN 30 DAYS BEFORE APPLICATION OF MARKING

MATERIALS. THOROUGHLY CLEAN SURFACES TO BE MARKED

BEFORE APPLICATION OF THE PAINT. REMOVE DUST, DIRT, AND

OTHER GRANULAR SURFACE DEPOSITS BY SWEEPING,

BLOWING WITH COMPRESSED AIR, RINSING WITH WATER, OR A

COMBINATION OF THESE METHODS AS REQUIRED. REMOVE

RUBBER DEPOSITS, EXISTING PAINT MARKINGS, RESIDUAL

CURING COMPOUNDS, AND OTHER COATINGS ADHERING TO

THE PAVEMENT BY WATER BLASTING ACCORDING TO THE

REMOVAL REQUIREMENTS AND PROCEDURES OUTLINED IN

SECTION 2. FOR PORTLAND CEMENT CONCRETE PAVEMENT,

GRINDING, LIGHT SHOT BLASTING, AND LIGHT SCARIFICATION,

TO A RESULTING PROFILE EQUAL TO ICRI 03732 CSP 2, CSP 3,

AND CSP 4, RESPECTIVELY, CAN BE USED IN ADDITION TO

WATER BLASTING, TO EITHER REMOVE EXISTING COATINGS OR

FOR SURFACE PREPARATION ON MOST PAVEMENTS: SHOT

BLASTING SHALL NOT BE USED ON AIRFIELD PAVEMENTS DUE TO THE POTENTIAL OF

FOREIGN OBJECT DAMAGE (FOD)

TO AIRCRAFT. SCRUB AFFECTED AREAS, WHERE OIL OR

GREASE IS PRESENT ON OLD PAVEMENTS TO BE MARKED, WITH

SEVERAL APPLICATIONS OF TRISODIUM PHOSPHATE SOLUTION

OR OTHER APPROVED DETERGENT OR DEGREASER AND RINSE

THOROUGHLY AFTER EACH APPLICATION. AFTER CLEANING

OIL-SOAKED AREAS, SEAL WITH SHELLAC OR PRIMER

RECOMMENDED BY THE MANUFACTURER TO PREVENT

BLEEDING THROUGH THE NEW PAINT. DO NOT COMMENCE

PAINTING IN ANY AREA UNTIL PAVEMENT SURFACES ARE DRY

AND CLEAN.

3.8 APPLICATION

APPLY PAVEMENT MARKINGS TO DRY PAVEMENT ONLY. THE

CONTRACTOR SHALL TEST THE PAVEMENT SURFACE FOR

MOISTURE BEFORE BEGINNING WORK AFTER EACH PERIOD OF

RAINFALL, FOG, HIGH HUMIDITY, OR CLEANING, OR WHEN THE

AMBIENT TEMPERATURE HAS FALLEN BELOW THE DEW POINT.

DO NOT COMMENCE MARKING UNTIL THE PAVEMENT IS

SUFFICIENTLY DRY AND THE PAVEMENT CONDITION HAS BEEN

APPROVED BY THE CO OR AUTHORIZED REPRESENTATIVE.

EMPLOY THE "PLASTIC WRAP METHOD" TO TEST THE

PAVEMENT FOR MOISTURE AS FOLLOWS: COVER THE

PAVEMENT WITH A 300 MM BY 300 MM (12 INCH BY 12 INCH)

SECTION OF CLEAR PLASTIC WRAP AND SEAL THE EDGES WITH

TAPE. AFTER 15 MINUTES, EXAMINE THE PLASTIC WRAP FOR

ANY VISIBLE MOISTURE ACCUMULATION INSIDE THE PLASTIC.

DO NOT BEGIN MARKING OPERATIONS UNTIL THE TEST CAN BE

PERFORMED WITH NO VISIBLE MOISTURE ACCUMULATION

INSIDE THE PLASTIC WRAP.
