Brush out all runs, sags, drips, and puddles.

Perform visual inspection for holidays and other defects.

CHECKPOINT 7 – STRIPE COAT APPLICATION

Verify environmental conditions (see CHECKPOINT 3).

Ensure overcoating window is as per manufacturer’s instructions.

After primer coat (mist coat after inorganic zinc), brush-apply un-thinned coat of same primer paint over edges, weld seams, cut-outs, and areas of complex geometries @ 3-4 mils wet film thickness (WFT).

CHECKPOINT 8 – TOP COAT APPLICATION

Ensure that system cure is in accordance with manufacturer's recommendation for intended service.

Ensure potable water tank exhaust ventilation is maintained continuously from and during coating application through final system cure, to exhaust all solvent to the atmosphere and to prevent solvent entrapment.

For immersion coatings (including tank U/W body), record date and time of the following events:

Final coat application: _____/_____; Return to service or removal from environment controls: _____/_____
