CONTAINERS MARKED IN PRINTS DISTINCTIVE COLOR OF THE LABEL OR IN LETTERS CLEARLY VISIBLE TO THE
NAKED EYE WITH THE FOLLOWING INFORMATION:

a. TYPE OF PAINT
b. BRAND OR TRADEMARK
c. NAME AND ADDRESS OF MANUFACTURER
d. NET VOLUME AND/OR MASS IN METRIC UNITS
e. DIRECTIONS FOR USE
f. SAFETY PRECAUTIONS
g. BATCH OR LOT NUMBER

3. CONSTRUCTION REQUIREMENTS

PRIOR TO COMMENCEMENT OF THE PAINTING, VARNISHING AND RELATED WORK, THE SURFACES TO BE APPLIED
SHALL BE EXAMINED IN ORDER NOT TO JEOPARDIZE THE QUALITY AND APPEARANCES OF THE PAINTING,
VARNISHING AND RELATED WORKS.
 3.1. SURFACE PREPARATION

CONCRETE AND MASONRY SURFACES SHALL BE COATED WITH CONCRETE NEUTRALIZER AND ALLOWED TO DRY
BEFORE ANY PAINTING PRIMER COAT IS APPLIED. WHEN SURFACE IS DRIED, APPLY THE FIRST COATING. HAIRLINE
CRACKS AND UNEVENNESS SHALL BE PATCHED AND SEALED WITH APPROVED PUTTY OR PATCHING COMPOUND.
AFTER ALL DEFECTS ARE CORRECTED APPLY THE FINISH COATS SPECIFIED ON THE PLANS (COLOR SCHEME
APPROVED).

IN ADDITION, THE FOLLOWING SHALL BE UNDERTAKEN PRIOR TO PAINTING, VARNISHING AND OTHER RELATED
WORKS:

a. VOIDS, CRACKS, NICK, AND OTHER WOOD IMPERFECTIONS WILL BE REPAIRED WITH PROPER PATCHING
MATERIAL AND FINISHED FLUSHED WITH SURROUNDING SURFACES.
b. PAINTING AND VARNISHING WORKS SHALL NOT BE COMMENCED WHEN IT IS TOO HOT OR COLD.
c. ALLOW APPROPRIATE VENTILATION DURING APPLICATION AND DRYING PERIOD.

3.1. APPLICATION

PAINTS WHEN APPLIED BY BRUSH SHALL BECOME NON-FLUID, THICK ENOUGH TO LAY DOWN AS ADEQUATE FILM
OF WET PAINT. BRUSH MARKS SHALL FLAWED OUT AFTER APPLICATION OF PAINT.

PAINTS MADE FOR APPLICATION BY ROLLER MUST BE SIMILAR TO BRUSHING PAINT. IT MUST BE NON-STICKY
WHEN THINNED TOM SPRAYING VISCOSITY SO THAT IT WILL BREAK UP EASILY INTO DROPLETS.

PAINT IS ATOMIZED BY HIGH PRESSURE PUMPING RATHER THAN BROKEN UP BY THE LARGE VOLUME OF AIR
MIXED WITH IT. THIS PROCEDURE CHANGE THE REQUIRED PROPERTIES OF THE PAINT.

3.2. MIXING AND THINNING

AT THE TIME OF APPLICATION, PAINT SHALL SHOW NO SIGN OF DETERIORATION. PAINT SHALL BE THOROUGHLY
STIRRED, STRAINED AND KEPT AT A UNIFORM CONSISTENCY DURING APPLICATION. PAINTS OF DIFFERENT
MANUFACTURE SHALL NOT BE MIXED TOGETHER. WHEN THINNING IS NECESSARY, THUS MAY BE DONE
IMMEDIATELY PRIOR TO APPLICATION IN ACCORDANCE WITH THE MANUFACTURER'S APPLICATION, BUT NOT IN
EXCESS OF ONE (1) PINT OF SUITABLE THINNER PER GALLON OF THE PAINT.

ENGINEER AND SUCH PLACE SHALL BE KEPT NEAT AND CLEAN AT ALL TIMES. NECESSARY PRECAUTION TO AVOID
FIRE MUST BE OBSERVED BY REMOVING OILY RAGS, WASTE, ETC. AT THEN END OF DAILY WORK.

3.4. CLEANING

ALL CLOTHS AND COTTON WASTE WHICH CONSTITUTE FIRE HAZARDS SHALL BE PLACED IN METAL CONTAINERS
OR DESTROYED AT THE END OF DAILY WORKS. UPON COMPLETION OF THE WORK, ALL STAGING, SCAFFOLDING
AND PAINT CONTAINERS SHALL BE REMOVED. PAINT DRIPS, OIL, OR STRAINS ON ADJACENT SURFACES SHALL BE
REMOVED AND THE ENTIRE JOB LEFT CLEAN AND ACCEPTABLE TO THE ENGINEER.

b. ALL COATS SHALL BE THOROUGHLY DRY BEFORE THE SUCCEEDING COAT IS APPLIED.
c. WHERE SURFACES ARE NOT FULLY COVERED OR CANNOT BE SATISFACTORILY FINISHED IN THE NUMBER OF
COATS SPECIFIED, SUCH PREPARATORY COATS AND SUBSEQUENT COATS AS MAY BE REQUIRED SHALL BE
APPLIED TO ATTAIN THE DESIRED EVENNESS OF SURFACE WITHOUT EXTRA COST TO THE OWNER.
d. WHERE SURFACES IS NOT IN PROPER CONDITION TO RECEIVE THE COAT THE ENGINEER SHALL BE NOTIFIED
IMMEDIATELY. WORK ON THE QUESTIONED PORTION(S) SHALL NOT START UNTIL CLEARANCE BE PROCEEED
IS ORDERED BY THE ENGINEER.
