Regarding substrate preparation using SSPC SP-10 blasting.
SSPC SP-10 is a standard for surface preparation, widely used for its high removal rate. It is necessary to remove more than 95% of contaminants adhered to the surface by blasting!
SSPC is a standard established by the Steel Structures Painting Council USA, and SP-10 (Near White Metal Blast Cleaning) requires the removal of more than 95% of visible surface contaminants (such as oil, dirt, rust, and oxides). The method of application only permits dry blasting. SSPC SP-10 is the second highest level of standard for surface preparation. The highest standard, SSPC SP-5, requires nearly 100% removal, which poses a cost issue. SSPC SP-10 necessitates the complete removal of rust adhered to the surface, while allowing for slight discoloration or shadows of mill scale and oxide films up to 5% of the surface area, thereby reducing costs while ensuring sufficient cleanliness, making it a widely used standard. By removing 95% of surface contaminants, it maximizes the performance of the paint and prevents early peeling of the coating, thereby extending the product's lifespan. Such specifications are chosen for harsh environments, such as highly corrosive coastal areas.
