If visible rusting is apparent, additional surface preparation will be required up to and including resandblasting, at the discretion of the engineer supervising the work. B. The final spray coat is to average 15o mils thick and in no case, less than 125 mils, and is to be free of runs, pin holes or other defects. C. The applied resin is to be allowed to cure for the time period and at the temperature specified by Armor Shield, before product is reintroduced into the tank. V1. INSPECTION A.

The Contractor is to notify owner of the time scheduled for closing the tank, so that an inspecton of the coated surface can be made. VIL CLOSING A. Where no hatch cover exists and a manhole has been cut out, the tank is to be sealed by the following method: using an oversized cover plate, having the same thickness as the tank, and overlapping the hole 2' on each side, bolt the plate securely over the opening through pre -drilled holes on 4" centers. Trowel material is to be applied around the opening to provide a seat for the cover plate. The cover plate is to be pre- formed to the curve of the tank and fit snugly to the tank surface at the plate edge. The plate and surrounding tank surfaces are to be sandblasted, the plate edge and bolts filled and rounded as in 4. E., and the entire area coated with trowel material or spray coat. B.
