Slurryblasting Standards Contents 1. 2. 3. 4. Introduction Format Explanatory Text Procedure For Using The Standards 5. Notes 6. References 7. Visual Standards 1 Introduction Slurryblasting is a technique for cleaning surfaces with a mixture of fresh water and abrasive where the elimination, or control of abrasive dust is required. Two slurryblasting systems are commonly encountered: • Pressurised water abrasive blasting, which uses water to propel the abrasive. • Air abrasive water blasting, which uses compressed air to propel the abrasive. This visual standard has been prepared by using pressurised...

3.2 Blast Standards The standard illustrates grade C and D surfaces prepared by slurryblasting to two different degrees of cleanliness. They are designated SB2 and SB21⁄2 and are comparable to Sa2 and Sa21⁄2 described in the ISO 8501-1:1988 surface preparation standard and to SSPC-SP6 and SSPC-SP10 of the Steel Structures Painting Council surface preparation standards. The definitions are: SB2 Thorough Slurryblast Cleaning When viewed without magnification, the surface shall be free from visible oil, grease, dirt, most paint coatings and foreign matter. Any remaining contamination shall be firmly...

5 Notes 5.1 Painted Steel The photographs in this standard were prepared from unpainted steel but they are also suitable for depicting the appearance of painted steel after slurryblasting. 5.2 Inspecting Slurryblasted Surfaces Prior to Flash Rusting When large areas are slurryblasted, flash rusting which obscures the original blast standard may occur before an inspection can be carried out. Establishing the required standard by blasting a small test area prior to the main blast may help, providing the rest of the job is blasted to the same standard. Methods of ensuring the rest of the job is...
