Thorough Spot & Sweep Blast Cleaning: A New Standard for an Old Practice
This webinar will present and discuss a new SSPC standard containing requirements for “spot and sweep” dry abrasive blast cleaning a previously coated carbon steel surface. This technique can be an economical way to maintain existing coatings which have some serviceable remaining life. The intent is to remove all unserviceable coating, clean any exposed steel to a near-white metal cleanliness, and uniformly roughen the remaining serviceable coating. This practice is not new, but SSPC-SP 18 is the first industry standard to comprehensively describe the practice.
Thorough spot and sweep blast cleaning is designed to subject the entire surface being prepared to significant abrasive impact. Coating that cannot withstand the abrasive blasting process is removed, while the remaining existing coating is suitably prepared for an additional layer of coating. Areas of exposed steel are prepared to the level of near-white metal blast cleaning.
Participation in this one-hour webinar will enable the attendee to:
Become familiar with SSPC SP-18, Thorough Spot and Sweep Blast Cleaning for Industrial Coatings Maintenance
Understand uses the standard is intended to cover and not cover
Understand the history of the standard
Understand inspection considerations unique to the standard
