PART 3 - EXECUTION

FIELD OBSERVATION

• Verify that surfaces are ready to receive work as instructed by the Product Manufacturer.

• Do not paint over conditions detrimental to the formation of a durable paint bond and film.

• Examine surfaces scheduled to be finished prior to commencement of work. Report any condition that may potentially affect proper application.

• Do not proceed with the work until unsatisfactory conditions have been corrected.

• Do not paint over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions otherwise detrimental to the formation of a durable paint film.

• Provide all necessary equipment, labor, rigging, lighting, and other equipment to facilitate inspections.

• The Owner/Project Manager may inspect the Work at any time for compliance with the requirements of the Specifications.

• The Owner/Project Manager reserves the right to approve each phase of the Work before further work is done, halt all Work deemed improper or not in compliance with the specification, and require the Contractor to correct improper practices or deficient Work.

• The Contractor is responsible for any expenses incurred in association with corrective measures required because of improper practices or defective or deficient work.

GENERAL REQUIREMENTS

• Provide adequate explosion-proof lighting sufficient to illuminate clearly the working area without shadows during all surface preparation and coating operations.

• Maintain adequate and continuous explosion-proof ventilation in confirmed areas during all surface preparation and coating operations and during all recoat and curing periods.

• Provide ventilation of sufficient capacity to maintain a clear atmosphere that is well below explosive and toxic limits.

• Arrange the ventilation system, including all fans and temporary duct work, so that no air spaces exist in any area.

• Heating devices used to create and/or maintain temperature conditions in compliance with specification requirements must be explosion proof and not exhaust sooty or oily residues or contaminants into the air.

• Heating devices are not to be used when existing temperature and humidity conditions may create dew point conditions.

• Use equipment that is explosion-proof and non-sparking. Spray equipment must be recommended by or acceptable to the Coatings Manufacturer.

• Apply caulking material only after the last coat of paint has been applied and has dried hard.

Caulking material must be compatible with the specified coating system. No paint on caulking material.

SURFACE PREPARATION

• General: Perform all preparation and cleaning procedures as specified and in strict accordance with the Paint Manufacturer's instructions for each substrate and atmospheric condition.

• Remove all the hardware, machined surfaces, plates, lighting fixtures, and similar items in place and not to be painted or provide surface protection prior to surface preparation and painting operations.

• Remove or reinstall the removed items by skilled workmen after the completion of painting.

• Clean surfaces are to be painted before applying paint or surface treatments. Remove oil and grease with clean cloths and cleaning solvents before mechanical cleaning.

• Ferrous Metals:

o Clean ferrous surfaces to be shopped primed of all oil, grease, dirt, mill scale, and other foreign matter by near-white blast cleaning (SSPC-SP 10).

o Clean submerged ferrous surfaces to be shop primed by white blasting (SSPC-SP 5).

o Clean non-submerged ferrous surfaces that have not been shop-coated by near-white blast cleaning (SSPC-SP 10).

o Clean submerged ferrous surfaces that have not been shop-coated or have been improperly shop coated by white blasting (SSPC-SP 5).

o Treat bare metal with metal treatment wash coat before priming if recommended by the

Paint Manufacturer.

o Touch-up shop-applied prime coats with primer after commercial blasting (SSPC-SP 6).

• Nonferrous Metal Surfaces: Clean nonferrous metal surfaces according to the coating system Manufacturer's instructions.

• Galvanized Surfaces:

o Clean free of oil and surface contaminants with a non-petroleum-based solvent complying with SSPC-SP 1.

o Build an angular profile of 1.5 miles or greater before application.

o Remove chromate treatments by sanding or other methods recommended by the Paint

Manufacturer.

• Concrete Surfaces:

o Exterior: Hydro blast exterior to remove all existing coating, chalk, dirt, dust, mildew, and other soluble contaminants by ultra-high pressure water blast cleaning (potable water) . All coating should be removed to return the tank exterior to bare concrete.

MATERIAL PREPARATION

• Mix and prepare painting materials in accordance with Manufacturer's directions.

• Store materials not in use in tightly covered containers. Maintain containers used for storage, mixing, and application clean and free of foreign materials.

• Stir materials before application to produce a mixture of uniform density and stir as required during the application. Do not stir the surface film into materials. Remove film and strain if necessary.

APPLICATION

• General:

o Apply paint with brush or roller. Other mechanical application techniques (power roller, air spray, or airless spray) that are allowed per Manufacturer's recommendations shall only be used as approved by Owner/Project Manager.

o Apply the first coat to surfaces that have been cleaned or pretreated.

o Allow sufficient time between successive coatings to permit proper drying. Do not recoat until the previous coat feels firm and does not deform or feel sticky under moderate thumb pressure.

o Limit roller applications to interior walls finish for second and third coats.

o Use spray application only for metal framework, siding, decking, wire mesh, and other surfaces recommended by the Paint Manufacturer.

o Apply each coat with spray equipment to provide the equivalent hiding of brush-applied coats.

o Use brushes suited for the material being applied.

o Use rollers of carpet, velvet back, or high pile sheeps wool as recommended by the Paint

Manufacturer for texture.

o The number of coats and paint film thickness are the same regardless of the application method. Do not apply succeeding coats until the previous coat has completely dried.

o Apply additional coats if undercoats or other conditions show through the final coat.

o Paint edges, corners, crevices, welds, and exposed fasteners to ensure equal film thickness.

o Finish exterior doors on tops, bottoms, and side edges the same as exterior faces unless otherwise specified.

o Paint aluminum parts in contact with dissimilar materials with the appropriate primer.

o Omit field primer on shop-primed metal surfaces; touch-up only as approved by

Owner/Engineer.

o Heating, Ventilating, and Electrical Work: Paint electrical items including grounding wire.

o Minimum Coating Thickness: Apply each material at no less than the Manufacturer's recommended spreading rate.

o Scheduling Painting:

o Prime Coats: Recoat primed surfaces where holiday or unsealed areas are detected to ensure no burn-through or defects.

o Brush Application: Brush all coats onto surfaces in an even film. Cloudiness, spotting, holidays, laps, brush marks, runs, sags, or other surface imperfections are unacceptable.

o Mechanical Applicators: Use mechanical methods only when permitted by governing ordinances and Paint Manufacturer and approved by Owner/Engineer.

PROTECTION

• Furnish and lay drop clothes in all areas where painting work is being done.

• Protect the work of other trades from the Work of this Section and leave it undamaged.

• Provide "Wet Paint" signs and remove all temporary protective wrappings after the completion of painting operations.

CLEAN-UP

• Remove discarded paint materials, rubbish, cans, and rags from the site at the end of each workday.

• Upon completion, clean all paint-spattered surfaces using proper methods to avoid scratching or damaging finishes.

• Touch-up and restore damaged or defaced painted surfaces as determined by the

PAINTING AND COATING SCHEDULE

• Painting and coating shall be in accordance with the schedule provided in Table A and

Section 2.05 described herein.

4.3 PRESTRESSED AND CAST-IN-PLACE CONCRETE STORAGE TANK REPAIR
