UHP waterjetting can be used effectively to reduce the cost and detrimental effects of maintenance recoating work in a variety of applications. This paper will review the surface preparation parameters of UHP waterjetting including surface cleanliness, visual appearance, and coatings life. Case studies of different types of applications will also be presented with historical data regarding chloride sampling on approximately 700,000 Ft2 of US Navy vessels as well as lead paint removal data on an abatement project consisting of over 400,000 Ft2 of steel will be presented New technology and improved procedures currently being used in the industry will be discussed as they apply to these case studies.
