How to Use This Calculator
- Enter the total steel surface area in sq ft to be blasted and primed.
- Select the SSPC prep level: 1=SP-6 Commercial Blast, 2=SP-10 Near-White, 3=SP-5 White Metal.
- Choose the primer type: 1=inorganic zinc (3.5 mil DFT), 2=epoxy (5 mil), 3=alkyd (2.5 mil).
- Read Abrasive Quantity (lbs) and Primer Quantity (gal) to order materials.
- Use Blasting Hours and Painting Hours to schedule crews and coordinate with the erection sequence.
- Estimated Total Cost combines abrasive, primer, and labor — use for coating budget line items.
