Regarding substrate preparation using blast cleaning.
About substrate preparation using blast.
"Benefits of Using ISO Sa2" ISO Sa2 is the third highest cleanliness standard in surface preparation. Higher standards such as ISO Sa3 and ISO Sa2.5 require the removal of almost all surface contaminants, but Sa2 allows for a broader range of acceptable conditions, making it possible to reduce costs and time. The acceptable level of adhered dirt is such that it does not detach with a putty knife that has no blade. Although some dirt may remain after blasting, the cleanliness is still superior compared to ISO St3, known as two-grade cleaning, and high adhesion of the paint is expected. By removing foreign substances through blasting and creating a rough surface, the performance of the paint can be maximized, preventing early peeling of the coating and extending the product's lifespan. This type of specification is chosen for products used outdoors. "Method for ISO Sa2 Work" 1. Remove slag, welding spatter, and other contaminants adhered to the surface. 2. Use solvents to remove oils, greases, and other substances adhered to the surface. 3. Remove all foreign substances adhered to the surface through blasting. 4. Use clean, dry air to remove dust and debris.
