Surface preparation using hand tools according to SSPC SP-2.
It is necessary to remove harmful substances with weak adhesion, but this is only permissible for those that are firmly attached. This is a standard used when it is difficult to prepare the substrate by blasting.
"What is SSPC SP-2?" SSPC is a non-profit organization in the United States that specializes in coatings for the protection of industrial and marine structures. It is one of the standards established for surface preparation. Surface treatment is performed using hand tools such as files, wire brushes, and scrapers. Harmful substances such as loosely adhered rust, mill scale, and paint films are removed, but firmly adhered rust, mill scale, and paint films are permissible. Inspection is conducted visually. "What do 'surface preparation' and 'substrate treatment' mean as written in the specifications?" Generally, it is considered equivalent to the ISO St2 standard.
