JOINT SURFACE PREPARATION STANDARD SSPC-SP 12/NACE NO. 5: SURFACE PREPARATION AND CLEANING OF STEEL AND OTHER HARD MATERIALS BY HIGH- AND ULTRAHIGH-PRESSURE WATER JETTING PRIOR TO RECOATING

This standard describes the surface preparation technique known as water jetting, which provides an alternative method of removing coating systems, including lead-based paint systems. Water jetting is effective in removing (1) deleterious amounts of water-soluble surface contaminants that may not otherwise be removed by dry abrasive blasting alone, specifically in the bottom of pits and craters of severely corroded metallic substrates; (2) surface grease and oil; (3) rust; (4) shotcreting spatter; and (5) existing coatings and linings. This standard addresses degrees of cleanliness, types of equipment, operating procedures, and safety factors associated with water jetting. Although this standard discusses jetting pressures up to 250 MPa (36,000 psi), higher pressures may be used as technology and equipment evolve.
