For example, spot repairs that are expected to provide 5 years of corrosion protection as a stopgap until more significant maintenance painting work can be performed may require a lesser degree of surface preparation SSPC-SP spc than a coating system that is expected to last 15 years.

SP 11, Bare Metal Power Tool Cleaning

The same types of power tools may be used to prepare surfaces for all three standards and may be electric sepc pneumatic powered. If a specific coating system or systems are included in the specification, the degree of surface preparation performed must be consistent with the coating requirements and the specified ep preparation. Similarly, power tool cleaning will not remove soluble salt contamination. Costs — The associated labor costs for surface preparation will vary inversely proportionally to the production rates listed above.

Power tool cleaning will not remove grease and oil contamination from the surface. Access — Areas that are difficult to access, like small internal spaces, back-to-back angles, etc. The specifications should state acceptable maximum levels of salt contamination and require testing after surface preparation has been performed and prior to painting. In many instances, chloride contamination can be reduced to acceptable levels by pressure water cleaning.
