1 Wet measurements will be taken immediately after the paint is applied in accordance with <br /> 2 ASTM D4414. Dry measurements will be taken after the coating is dry and hard in <br /> 3 accordance with SSPC Paint Application Specification No. 2. <br /> 4 <br /> 5 Each painter shall be equipped with wet film thickness gages and shall be responsible for <br /> 6 performing frequent checks of the paint film thickness throughout application. <br /> 7 <br /> 8 Coating thickness measurements may be made by the Engineer after the application of <br /> 9 each coat and before the application of the succeeding coat. In addition, the Engineer <br /> 10 may inspect for uniform and complete coverage and appearance. One hundred percent <br /> 11 of all thickness measurements shall meet or exceed the minimum wet film thickness. In <br /> 12 areas where wet film thickness measurements are impractical, dry film thickness <br /> 13 measurements may be made. If a question arises about an individual coat's thickness or <br /> 14 coverage, it may be verified by the use of a Tooke gage in accordance with ASTM D4138. <br /> 15 <br /> 16 if the specified number of coats does not produce a combined dry film thickness of at least <br /> 17 the sum of the thicknesses required per coat, if an individual coat does not meet the <br /> 18 minimum thickness, or if visual inspection shows incomplete coverage, the coating system <br /> 19 will be rejected and the Contractor shall discontinue painting and surface preparation <br /> 20 operations and shall submit a Type 2 Working Drawing of the repair proposal. The repair <br /> 21 proposal shall include documentation demonstrating the cause of the less-than-minimum <br /> 22 thickness, along with physical test results, as necessary, and modifications to Work <br /> 23 methods to prevent similar results. The Contractor shall not resume painting or surface <br /> 24 preparation operations until receiving the Engineer's acceptance of the completed repair. <br /> 25 <br /> 26 6-07.3(9)E Surface Temperature Requirements Prior to Application of Paint <br /> 27 This section, including title, is revised to read: <br /> 28 <br /> 29 6-07.3(9)E Environmental Condition Requirements Prior to Application of <br /> 30 Paint <br /> 31 Paint shall be applied only during periods when: 11132 <br /> 33 1. Air and steel temperatures are in accordance with the paint manufacturer's <br /> 34 recommendations but in no case less than 35°F nor greater than 115°F. <br /> 35 <br /> 36 2. Steel surface temperature is a minimum of 5°F above the dew point. <br /> 38 3. Steel surface is not wet. ' <br /> 39 <br /> 40 4. Relative humidity is within the manufacturer's recommended range. <br /> 41 <br /> 42 5. The anticipated ambient temperature will remain above 35°F or the <br /> 43 manufacturer's minimum temperature, whichever is greater, during the paint <br /> 44 drying and curing period. <br /> 45 <br /> 46 Application will not be allowed if conditions are not favorable for proper application and <br /> 47 performance of the paint. <br /> 48 <br /> 49 Paint shall not be applied when weather conditions are unfavorable to proper curing. if a <br /> 50 paint system manufacturer's recommendations allow for application of a paint under <br /> 51 environmental conditions other than those specified, the Contractor shall submit a Type 2 <br /> 52 Working Drawing consisting of a letter from the paint manufacturer specifying the <br /> CITY OF EVERETT AMENDMENTS <br /> PACIFIC AVENUE TO INTERURBAN TRAIL BICYCLE SAFETY PROJECT 8/12/2019 <br /> STATE FUND#HLP PB17(014); COE#PW3688 Page AM-48 <br /> 111 <br />
