SPECIFICATIONS

SECTION 09 97 02 PAINTING: HYDRAULIC STRUCTURES. Paragraph 3.2.9.2 which currently reads:

3.2.9.2 Vinyl Zinc-Rich Primer

Mix the primer combining components A, B, and C. Mix in accordance with label instructions. After mixing, keep the paint covered at all times to avoid contamination and apply within eight days after it is mixed. When the ambient and/or steel temperature is below about 80 degrees F, the paint will not normally require thinning; however, direct special attention toward ensuring the paint at all times contains sufficient volatiles (thinners) to permit it to be satisfactorily atomized and to provide a wet spray and to avoid deposition of particles that are semidry when they reach the surface. Stir the paint continuously during application at a rate that will prevent the zinc dust from settling. When spraying is resumed after any interruption of longer than 15 minutes, vigorously whip the entire length of the material hose until any settled zinc is redispersed. Avoid long periods of permitting the paint to remain stagnant in the hose by emptying the hoses whenever the painting operation is to be suspended for more than 1 hour. Keep the material (paint) hoses as short as practicable, preferably not more than 50 feet in length. Equipment used for spraying this zinc primer must not be used for spraying other vinyl-type paints without first being thoroughly cleaned, since many of the other paints will not tolerate zinc contamination. Do not use any type of hot spray. An average dry film thickness of up to 2.5 mils may be applied in one double-spray coat. Do not allow more than 8 days to elapse after application of a VZ-108d zinc-rich coat before it receives a succeeding coat.

Is now changed to read:

Do not allow more than 8 days to elapse after application of a VZ-108d zinc-rich coat before it receives a succeeding coat. It is authorized to extend the recoat time where prime-painted pieces are assembled, bolted and retensioned three weeks after initial tensioning such that retensioning can be accomplished prior to subsequent coats of pain. Ensure that the primed surfaces to receive paint are clean and dry prior to application of successive coats. Water must be used to remove dust. Detergent must be used to remove grease and oil.

SECTION 09 97 02 PAINTING: HYDRAULIC STRUCTURES Paragraph 3.2.10.4 Which currently reads:

3.2.10.4 Repair of Vinyl Coating Defects

Coating defects should be repaired when they are first observed but must be repaired prior to coating acceptance. Runs and sags may be brushed out before becoming dry. Pinholes must be physically closed by scrubbing with a brush wet with ketone solvent before the succeeding coat is applied. Overspray that will not be melted smooth by the succeeding coat must be removed by scrubbing with a brush wet with ketone solvent. Minor overspray in the final coat that results only in a reduced gloss at the outer limits of the spray pattern is not considered a defect and requires no additional attention. Insufficient thickness or incomplete hiding must be corrected with additional paint before the succeeding coat is applied. If any defect extends to the substrate, it must be determined if the substrate is corroding. In the case of pinholes it may be necessary to use magnification to observe the substrate. If the substrate is showing any corrosion, the required surface preparation must be restored by spot blasting, and the entire coating system replaced at that location. Following the spot blasting the edges of the remaining coating must be scrubbed with ketone solvent to assure all remaining coating is tightly adhering before the new coating is applied. If VZ-108 does not receive the required succeeding coat within the required 8 days, it must be removed by abrasive blasting and replaced.

For connection bolt tensioning sessions, the same paint application process specified herein applies. Once the initial coat of V-766e is applied there is no recoat window.

SECTION 09 97 02 PAINTING: HYDRAULIC STRUCTURES Paragraph 3.2.5 Which currently reads:

3.2.5 Contacting Surfaces

When riveted or ordinary bolted contact is to exist between surfaces of ferrous or other metal parts of substantially similar chemical composition, such surfaces will not be required to be painted, but any resulting crevices must subsequently be filled or sealed with the three coat 5-E-Z paint system as specified.

Where a nonmetal surface is to be in riveted or bolted contact with a metal surface, the contacting surfaces of the metal must be cleaned and given three coats of the 5-E-Z paint system. Unless otherwise specified, corrosion-resisting metal surfaces, including cladding therewith, must not be painted.

Is now changed to read:

3.2.5 Contacting Surfaces

Bolted connection faying surfaces must be painted with primer only before connector installation. Where a nonmetal surface is to be riveted or is a bolted contact with a metal surface, the contacting surfaces of the metal must be cleaned and given three coats of the 5-E-Z paint system. Unless otherwise specified, corrosion-resisting metal surfaces, including cladding therewith, must not be painted.

SECTION 09 97 02 PAINTING: HYDRAULIC STRUCTURES. Paragraph 3.5 Which currently reads:

3.5 Painting Schedule SYSTEM NO. 5-E-Z

Items or surfaces to be coated: All ferrous surfaces (excluding two contacting ferrous surfaces, stainless steel surfaces, and rubber seals unless the nonmetal surface is in contact with a metal surface). Refer to paragraph Contacting Surfaces within this section for further clarification.

Is now changed to read:

3.5 Painting Schedule SYSTEM NO. 5-E-Z

Items or surfaces to be coated: All ferrous surfaces (excluding stainless steel surfaces, and rubber seals unless the nonmetal surface is in contact with a metal surface). Refer to paragraph Contacting Surfaces within this section for further clarification.

SECTION A - SOLICITATION/CONTRACT FORM
