All exterior surfaces shall be abrasive blast cleaned to a Near-White Metal Blast Cleaning, removing all existing paint, rust, dirt, mill scale and foreign matter by the recommended methods outlined in the SSPC Society of Protective Coating`s Specification SP-10. A minimum angular blast profile of 2.0 mils is required. 2. EXTERIOR COATING SPECIFICATIONS: *See Attachment A. MATERIAL SPECIFICATIONS for primer and finish paint specifications PRIME COAT: Immediately after blasting and before any rusting occurs (within 12 hours maximum), apply one coat of Tnemec Series 91-H2O Hydro-Zinc to all bare steel surfaces. This coating shall be applied at a dry film thickness of 2.5 - 3.5 mils. INTERMEDIATE COAT: Apply one complete coat of Tnemec Series N69-color Hi-Build Epoxoline II at a dry film thickness of 2.0 - 3.0 mils. FINISH COAT: Apply one complete coat of Tnemec Series 1075 -color* Endura-Shield II at a dry film thickness of 2.0 - 3.0 mils * Color to be Pantone 432c or equal color upon Owner approval 3. QUALITY OF PAINT: The paint products mentioned above in 2. Exterior Coating Specifications are set up as standards of quality. The standard "or equal" clause shall apply. 4. APPLICATION OF PAINT: The Contractor shall apply each coating in accordance with these specifications and the paint manufacturer`s recommendations. The coating shall be applied at the specified thickness. If the specified thickness is not obtained, an additional coat(s) of paint shall be applied. All paint shall be applied in strict accordance with the applicable manufacturer`s printed data sheet and container label outlining recommended minimum and maximum surface and air temperatures required for application. Paint shall not be applied to wet or damp surfaces and shall not be applied in rain, snow, fog or mist, or when the relative humidity exceeds 85%. No paint shall be applied when it is expected that the relative humidity will exceed 85% and/or the air temperature will drop below recommended levels within 12 hours after paint application. Dew or moisture condensation should be anticipated, and if such conditions are prevalent, painting shall be delayed until certain that the surfaces are dry. Painting should be completed well in advance of the probable time of day when condensation will occur in order to permit the film an appropriate drying time prior to the formation of moisture on the surface. 5. CONTAINMENT / DISPOSAL REQUIREMENTS: When required by federal, state or local regulation, surface preparation debris must be contained and removed from all well sites.
