Most of atmospheric coatings and tank linings for offshore maintenance are routinely applied on rusted steel after dry abrasive blasting. It is well known that the salt contamination on rusted steels cannot be completely removed by dry abrasive blasting alone. Residual salt contamination, which is hidden in the corrosion pits, is difficult to remove mechanically. Depending on the rust severity, the residual salt content on the dry abrasive blasted steel surface can be in the range of 5-65 μg/cm2. Too much residual salt contamination can be detrimental to coating performance. It could cause coating blistering, adhesion degradation, and under film corrosion which will result in a shorter service life, particularly in immersion service such as pipeline coatings or tank linings. Recently wet abrasive blasting (WAB) has been used as the surface preparation in conjunction with the decontamination chemicals.

The authors look toward the future of specifying coating projects starting with the traditional prescriptive, means-and-methods, coating formula-based specifications. The popular qualified product list (QPL) approach is presented along with its drawbacks. The design/build (DB) ideal and limitations of specifying only performance is presented.
This standard, SSPC-SP 14 (WAB)/NACE WAB-8, defines the "Industrial" level of surface cleanliness for wet abrasive methods. Other levels in overview below.
HISTORICAL DOCUMENT. Procedures, equipment, and materials used for air/water/abrasive, water/abrasive, and pressurized water/abrasive blasting. Inhibitors, equipment maintenance & safety guidelines also included.
With more stringent silica regulations being enforced, wet abrasive blasting is becoming more prevalent in the industry. We investigated the viability of wet abrasive blasting as compared to the more commonly used dry abrasive blast. One added benefit of wet abrasive blasting is the removal of soluble salts in addition to providing the specified profile.
