V. APPLICATION A. The coating resins should be applied immediately alter the sandblasting operation is completed, but application must begin no later than 16 hours following and before, any visible rusting occurs. If visible rusting is apparent, additional surface preparation will be required up to and including resandblasling, at the discretion of the engineer supervising the work. 11. The final spray coat is to average 150 mils thick and in no case, less than 125 mils, and is to he free of runs, pin holes or wher 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 lank. VI. INSPECTION A. 'file Contractor is to nolifv Owner of file Scheduled starling time for the application process so that, if desired, an inspection of the sandblasted surface can be made. A. The Contractor is to notify owner of the time scheduled for closing the tank, so that an inspectrn of the coated surface can be made. VII. CLOSING A. Where no hatch cover exists and a manhole has been cut out, the tank is to be scaled by the following method: using an oversized cover plate, having the same thickness as the tank, and overlapping the hole 2' on each side, boll 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 coaled with trowel material or spray coat. B. Allow the plate coating to cure. Fill the excavation. All rubbish and debris shall be removed from the site and the work area swept clean.
