Because a clean sandblasted surface (using fresh sand, not recycled sand) is the ideal surface for adhesion, we recommend applying RustSeal directly to a sandblasted surface without the RustBlast step. Be sure to wear gloves when handling the sandblasted piece to prevent finger oils from contaminating the surface before coating.
With that said, you can apply RustBlast to a sandblasted surface before RustSeal if desired — but be aware the surface will be more prone to flash rust if not dried immediately after rinsing. To avoid this, skip RustBlast and apply RustSeal directly for the cleanest, fastest result.
Review the complete RustSeal Application Directions before starting your project for proper application and cure time guidance.
