capable of withstanding winds up to 25 mph. Containment and lead <br />abatement plan must be submitted to Engineer for approval. <br />(3) Abrasive blast clean the entire exterior surface area to SSPC-SP 6 <br />Commercial Blast Standard. A suitable angular anchor profile of at least <br />2.0 mils as determined by Test-Tex strips shall be established. All areas <br />shall be pressure washed with clean water per SSPC SP-1 prior to <br />blasting to prevent embedment of contaminants from existing coating. If <br />containment is lowered or removed for any reason during blasting or <br />painting operations, surface must be pressure washed with clean water <br />per SSPC SP-1 to remove surface contaminants prior to continuing work. <br />(4) Repair deep pits by welding. Shallow pits shall be repaired with 100% <br />solids epoxy paste after zinc-rich primer is applied. <br />(5) Apply four coat Zinc Rich Primer/ Epoxy/ Polyurethane/ Fluor opolymer <br />system: <br />Prime coat: Tnemec Series 94 H20 Hydro-Zinc applied @ 2.5-3.5 mils <br />DFT. <br />Stripe coat: Tnemec Series 20 or 66 polyamide epoxy thinned as much as <br />allowable and brushed into all weld seams. <br />1St Intermediate coat: Tnemec Series 20 or 66 polyamide epoxy applied <br />@ 4-5 mils DFT. <br />2na Intermediate coat: Tnemec Series 750 polyurethane applied at 2.5-4 <br />mils DFT. <br />Finish coat: Tnemec Series 700 Hydroflon fluoropolymer applied @ 2-3 <br />mils DFT. <br />Total system thickness must be 10.0 mils DFT minimum. Each <br />succeeding coat of paint will vary from the preceding in color so as to be <br />able to verify coverage. Color of finish coat of paint will be determined <br />by Owner after Contractor submits color choices chart. <br />(6) After all exterior painting is complete; install two (2) logos on sides of <br />tank similar to existing logos. Use Tnemec Series 700 Hydroflon for <br />logos. Engineer shall provide logo detail to Contractor upon approval <br />by Owner. All dimensions to be field verified by Contractor prior to <br />ordering pounce patterns. Contractor shall use DuPont Tyvek pounce <br />patterns, or equal, as provided by TankLogos.com of Nashville, TN. <br />Phone: (615) 473-0272. <br />D.
