I1 Paint shall be stored and mixed in a secure, contained location to eliminate the potential for <br /> 2 spills into State waters and onto the ground and highway surfaces. <br /> I <br /> 3 <br /> 4 6-07.3(9)D Coating Thickness <br /> 5 This section is revised to read: <br /> 1116 <br /> 7 Dry film thickness shall be measured in accordance with SSPC Paint Application <br /> 8 Specification No. 2, Procedure for Determining Conformance to Dry Coating Thickness <br /> 9 Requirements. <br /> 110 <br /> 11 The minimum dry film thickness of the primer coat shall not be less than 2.5 mils. <br /> 12 <br /> I13 The minimum dry film thickness of each coat (combination of intermediate and intermediate <br /> 14 stripe, and top) shall be not less than 3.0 mils. <br /> 15 <br /> I <br /> 16 The dry film thickness of each coat shall not be thicker than the paint manufacturer's <br /> 17 recommended maximum thickness. <br /> 18 <br /> I l 9 <br /> The minimum wet film thickness of each coat shall be specified by the paint manufacturer <br /> 20 to achieve the minimum dry film thickness. <br /> 21 <br /> I22 Film thickness, wet and dry, will be measured by gages conforming to Section 6-07.3(8)A. <br /> 23 <br /> 24 Wet measurements will be taken immediately after the paint is applied in accordance with <br /> I <br /> 25 ASTM D4414. Dry measurements will be taken after the coating is dry and hard in <br /> 26 accordance with SSPC Paint Application Specification No. 2. <br /> 27 <br /> 28 Each painter shall be equipped with wet film thickness gages and shall be responsible for <br /> I29 performing frequent checks of the paint film thickness throughout application. <br /> 30 <br /> 31 Coating thickness measurements may be made by the Engineer after the application of <br /> I <br /> 32 each coat and before the application of the succeeding coat. In addition, the Engineer may <br /> 33 inspect for uniform and complete coverage and appearance. One hundred percent of all <br /> 34 thickness measurements shall meet or exceed the minimum wet film thickness. In areas <br /> ' 35 where wet film thickness measurements are impractical, dry film thickness measurements <br /> 36 may be made. If a question arises about an individual coat's thickness or coverage, it may <br /> 37 be verified by the use of a Tooke gage in accordance with ASTM D4138. <br /> I38 <br /> 39 If the specified number of coats does not produce a combined dry film thickness of at least <br /> 40 the sum of the thicknesses required per coat, if an individual coat does not meet the <br /> 41 minimum thickness, or if visual inspection shows incomplete coverage, the coating system <br /> I42 will be rejected and the Contractor shall discontinue painting and surface preparation <br /> 43 operations and shall submit a Type 2 Working Drawing of the repair proposal. The repair <br /> 44 proposal shall include documentation demonstrating the cause of the less-than-minimum <br /> I45 thickness, along with physical test results, as necessary, and modifications to Work <br /> 46 methods to prevent similar results. The Contractor shall not resume painting or surface <br /> 47 preparation operations until receiving the Engineer's acceptance of the completed repair. <br /> I48 <br /> 49 6-07.3(9)E Surface Temperature Requirements Prior to Application of Paint <br /> 50 This section, including title, is revised to read: <br /> 151 <br /> City of Everett Page AM-45 Amendments <br /> Everett Downtown Streetscape Improvement March 22, 2019 <br />
