SSPC-SP3 requires power tools to sspc-sp1 solvent cleaning used in a manner that prevents the formation of cleaniing, sharp ridges, and sharp cuts. In this case the area damaged and in need of repair by a paint containing zinc dust will receive a blast per SSPC-SP10 before the paint is applied. Hand tool cleaning also acceptably cleans a hot-dip galvanized surface sspc-sp1 solvent cleaning surface profiling according to D However, some rust remaining at the bottom of pits is acceptable if the surface was pitted to begin with.
