EXECUTION
SAFETY
Coatings specified may have potential health hazards if ingested or
improperly handled. Follow manufacturer's written safety precautions
throughout the mixing, application, and cure of the coatings.
3.2
PROTECTION FROM TOXIC AND HAZARDOUS CHEMICAL AGENTS
During surface preparation, and paint application phases, ensure employees
are adequately protected from toxic and hazardous chemical agents which
exceed the concentrations in 29 CFR 1910.1000. Comply with respiratory
protection requirements in 29 CFR 1910.134.
3.2.1
Epoxy-Polyamide Coating Hazards
MIL-P-24441 formulations have a minimum flash point of 95 Degrees F.
Solvent fumes from epoxy paint systems are combustible and toxic. Take
suitable precautions to prevent their accumulations. In addition to fire
and toxic hazard, epoxy coatings can cause allergic reactions when allowed
to come in contact with the skin. Prompt skin cleanup after contact using
soap and water, not solvents, is recommended. Solvents will thin and
spread paint over the skin, permitting deeper penetration and increasing
the hazard of a delayed allergic reaction.
3.2.2
Health
Operations shall be reviewed and approved by an industrial hygienist as to
correctness of work procedures and personal protective equipment. Services
of the industrial hygienist shall be obtained by the Contractor.
3.3
WEATHER CONDITIONS
Accomplish abrasive blasting and coating operations when the ambient air
temperature is above 40 degrees F, and below 95 degrees F, and the steel
surface temperature is more than 5 degrees F above the dew-point of the
ambient air. Coatings shall not be applied to damp or wet surfaces.
3.4
SURFACE PREPARATION
Grind rough surfaces smooth on weld seams, sharp edges, and corners to a
minimum of a 1/8 inch radius. Remove visible oil, grease, drawing and
cutting compounds by SSPC SP1 solvent cleaning. Then, abrasive-blast
surfaces to near-white metal in accordance with SSPC SP 10. Provide a
surface profile of 1-1/2 mil thickness. Prior to commencing blasting,
prepare a 12 inch square steel test-plate for the appearance shown in
SSPC VIS 1. Submit the sample to the Contracting Officer. Use the
approved sample test-plate as a standard of comparison for the tank
surfaces throughout the course of work. Keep test plate wrapped and sealed
using vapor tight material in order to retain the appearance. Blasting
equipment shall be conventional air, force-feed, or pressure type. No type
of water or vapor blast will be permitted. Provide nozzle of such size
that a pressure of 90 plus or minus 10 psig is maintained at the blast
generator. Filter and separate oil and moisture from the air supply, and
determine quality of air by blowing through a clean cloth. Blast in
sections or blocks small enough to permit application of the epoxy coating
during the same working shift. Time interval between blasting and
application of the epoxy coating shall not exceed 8 hours. Abrasive-blast
surfaces shall match the prepared test-plate. After abrasive-blasting,
clean surfaces by brushing, blowing with oil-free and moisture-free
compressed air, or vacuuming. Free surfaces of dust and debris. Weld
sharp depressions or deep pits and grind-off smooth.
3.5
3.5.1
APPLICATION OF COATING SYSTEM
General (Epoxy Coating System)
Dry film thickness (DFT) for the epoxy coating system shall be as specified
below. The complete epoxy coating system shall be:
Primer: 3 to 4 mils DFT.
Intermediated Coat: 3 to 4 mils DFT.
Topcoat: 3 to 4 mils DFT.
3.5.2
General Procedure
Provide the epoxy coating system and two coats of the antifouling paint to
all metal surfaces. Apply primer coat as soon as practical after abrasive
blast cleaning. In no case shall the time interval exceed 4 hours. If
visible rusting occurs; regardless of the time period, reblast the surface
prior to applying primer coat. Coating system shall be applied by
experienced applicators. Apply two coats of primer over corners, crevices,
and welds. Apply the additional coat of primer by brush, working the
material into corners, crevices, and welds, and outside corners and angles
after the general application of the primer coat. Allow previous coat to
dry to tack-free condition but not more than 72 hours before applying the
next coat. If more than 72 hours should elapse between coats, then clean
the surface and apply a fog coat at a minimum dry film thickness of one
mil, using the same material as the previous coat. Allow the fog coat to
become tacky, and then apply the subsequent coat. The total dry film
thickness (DFT) of the coating system shall be not less than 9 mils. If
necessary to obtain the required minimum thickness of 9 mils an additional
topcoat shall be applied within 16 hours.
3.5.3
Epoxy-Polyamide Coating Application
Epoxy-polyamide coatings, MIL-P-24441, may be applied by brushing,
airless spraying, or dip application.
3.5.4
Antifouling Paint
While the last coat of epoxy-polyamide is still tacky, apply the first coat
of antifouling paint. After the first coat is dry, apply a second coat.
Total minimum dry film thickness for both coats shall be 4 mils.
3.6
FINAL INSPECTION
Following completion and curing of the coating system, inspect coated
surfaces for pinholes, blisters, inadequate coating thickness, and other
defects. Measure the dry film thickness in accordance with SSPC PA 2
at several random points throughout the tank as designated by the
Contracting Officer. Repair imperfections found or so designated by the
Contracting Officer. NOTE: If the average is less than the specified
minimum dry film thickness, take additional readings in adjacent areas to
define the extent of the thin area. Coat such areas with white
polyurethane topcoat as necessary to achieve specified thickness. Apply
coating within the conditions specified in paragraph entitled "Application
of Coating System." Lightly brush blast or hand sand thin areas found to
remove the glossy surface of the topcoat before applying additional topcoat
if the topcoat was applied more than 48 hours in advance.
3.7
Final Cleanup
Following completion of the work, remove debris, equipment, and materials
from the site. Remove temporary connections to Government or Contractor
furnished water and electrical services. Restore existing facilities in
and around the work areas to their original condition.
