A number of important parameters need to be monitored during the blasting or water jetting process, these include: air pressure (at the nozzle), nozzle diameter, blast media contamination & pH values in order to avoid recontamination of the substrate during blasting.
Abrasives used for blast cleaning surfaces can be contaminated with soluble salts due to the source or the re-use of the blasting media. This contamination can be transferred to the blast cleaned surface and result in accelerated corrosion conditions and also cause premature coating failure if this contamination is not removed prior to applying the coating.

Elcometer Guide to Surface Preparation
Surface preparation is one of the most important factors in the successful application of a coating or surface treatment and is critical to the effective lifetime of the coating.
