Project condition records: a. Measure and record ambient air and substrate temperature at the beginning and end of each shift and once every two hours of each shift using a thermometer. b. Measure and record relative humidity at the beginning and end of each shift and every two hours of each sift using a sling psychrometer in accordance with ASTM E 337. 3. Coating application: a. Inspect and record that the pot life of the coating system materials is not exceeded during installation. Inspect to verify that recoat limitations for all coating materials are not exceeded. b. Measure and record the thickness of each coat of the coating systems using the following methods: 1) Use notched gauge in accordance with ASTM D 4414 for Wet Film Thickness at least once every 50 square feet of coating system area. 2) Following cure, measure the dry film thickness of coatings using dry film thickness gages once for every 50 square feet of surface area. Measurement should be performed in accordance with SSPC-PA-2 using magnetic gages for ferrous metal substrates and using electronic gages for non-ferrous metal substrates. Measurements should be taken for each coat in the coating system, but not until at least 8 hours after application of the coating. If recoat times are shorter than 8 hours, rely on wet film thickness gage measurements for each coat. Any areas found to be below the specified DFT shall receive additional applications of the coating system or shall be removed and recoated if recoat times have been exceeded. Areas found to be over specified DFT must be evaluated. If thickness is 1 to 3 mils over specified DFT, no action shall be required provided runs and sags are not present. If mil thickness is too excessive, removal and recoating will be required by the Contractor at no additional cost to Owner. c. Thickness of coatings shall be checked with a nondestructive, magnetic- type thickness gauge. Use an instrument such as a Tooke Gauge if a destructive tester is deemed necessary. Test coating integrity of all interior wetted surfaces with an approved inspection device. Holiday detectors shall not exceed voltage recommended by manufacturer of coating system. For thickness between ten (10) and twenty (20) mils, add a non- sudsing type wetting agent to water prior to wetting detector sponge. No pinholes or other irregularities will be permitted in final coating. d.
