Delivery Date: 18-Apr-2011 Actual Date Received: 18-Apr-2011 Sent To: Eric Christiansen (First Recipient) Requested By: 2-May-2011 4:30 PM CT Copy to: Eric Little Nick Jacob Todd Henson Derek Dodson History (Chronological Order) Type Routed Memo Under the “Painting Notes” on S1-22 for Ponte and S2-18 for Bella, we state that “Cleaning and painting shall be in accordance with Item 446, ‘Cleaning and Painting Steel’ and Manufacturer’s instructions.” Per the product data for Carboguard 893 (intermediate coat) surface preparation for steel shall be “SSPC-SP6 with a 1.0-2.0 mil (25-50 micron) surface profile.” The product data for the top coat (Carbothane 134 HS) is much more general and just says to “employ an adequate method.” We are recommending that the manufacturer-specified SSPC-SP6(commerical blast cleaning) technique be used prior to the application of the intermediate coat. The contractor may use the desired cleaning method (Simple Green detergent with brushes) prior to the application of the top coat, but not prior to the application of the intermediate coat. For your benefit, we’ve attached a chart that provides basic definitions for the different levels of cleaning.
