Industrial Sandblasting

What is Industrial Sandblasting?

Industrial sandblasting, more accurately referred to as abrasive blast cleaning, is the controlled process of propelling abrasive media at high velocity against a surface to remove corrosion, contaminants, and existing coatings while creating a precise anchor profile. This profile is critical, enabling protective coatings to mechanically bond to the substrate for long-term performance.

While the term “sandblasting” is still widely used, modern industrial blasting rarely involves sand. Due to serious respiratory risks associated with silica sand, today’s processes rely on engineered abrasive media selected for the specific substrate, required profile depth, coating system, and environmental conditions. BlasTek uses a full spectrum of media including steel grit, steel shot, garnet, aluminum oxide, glass bead, crushed glass, baking soda, walnut shells, corn cob, and specialty abrasives, tailoring each approach to the unique demands of the project. No two surfaces or specifications are treated the same.

Within abrasive blasting lies a complex and highly technical discipline involving media selection, surface preparation standards, and evolving application technologies. Our team remains at the forefront of these advancements to ensure optimal results for every client and application.

The quality of industrial sandblasting ultimately determines coating performance. Industry data consistently shows that 80% or more of coating failures can be traced back to inadequate surface prep. At BlasTek, blasting is not just a cleaning step, it is a critical, engineered process that establishes the foundation for coating adhesion, durability, and long-term asset protection.

SSPC and NACE Surface Preparation Standards

BlasTek applies the appropriate surface preparation standard based on the coating system, substrate condition, and service environment, never a one-size-fits-all approach. Our in-house coatings inspectors ensure every project is aligned with the latest NACE, SSPC, and AMPP (formerly NACE/SSPC) standards, so specifications are not only met, but verified with precision. This level of oversight ensures our work consistently supports long-term coating performance in even the most demanding conditions.

Key abrasive blast cleaning standards we routinely achieve include:

NACE No. 1 / SSPC-SP5 — White Metal Blast

The highest level of surface cleanliness achievable through abrasive blasting. All visible contaminants are removed, leaving a uniform white or gray appearance. This standard is required for immersion service, aggressive chemical exposure, and high-performance coating systems where maximum adhesion and longevity are critical.

NACE No. 2 / SSPC-SP10 — Near-White Metal Blast

Permits up to 5% staining per unit area. Commonly specified for severe service environments, including tanks, vessels, and water or wastewater infrastructure, where near-maximum coating performance is required.

NACE No. 3 / SSPC-SP6 — Commercial Blast

Removes all visible oil, grease, dirt, rust, mill scale, and coatings, while allowing limited staining (up to 33%). This is a widely used standard for atmospheric service applications requiring durable, long-term protection without immersion exposure.

NACE No. 4 / SSPC-SP7 — Brush-Off Blast

Removes loose rust, mill scale, and coatings while allowing tightly adherent material to remain. This standard is typically used when existing coatings are being overcoated or encapsulated, offering a more economical approach to surface preparation.

SSPC-SP18 — Thorough Spot and Sweep Blast Cleaning

A combined approach that integrates brush-off blasting with targeted spot blasting to higher standards (such as SP5 or SP10) in localized areas. Ideal for maintenance and repair projects where selective surface preparation is required to address corrosion while preserving intact coatings.

Industrial Sandblasting Applications

BlasTek’s industrial sandblasting services support a wide range of assets across demanding industries, with each project tailored to the substrate, exposure conditions, and coating requirements:

• Structural steel: Surface preparation of beams, columns, trusses, and framing systems for both new construction and rehabilitation projects
• Storage tanks and vessels: Internal and external blasting for water, chemical, fuel, and process storage, ensuring proper prep for linings and protective coatings
• Piping systems, weldments, and fabricated assemblies: Shop-based blast cleaning to specification prior to coating, handling, and shipment
• Industrial equipment: Restoration and preparation of heavy machinery, conveyors, process equipment, and heat exchangers
• Bridges and elevated structures: Corrosion removal and surface preparation for maintenance, repair, and full recoating programs
• Secondary containment systems: Preparation of concrete and steel substrates for seamless liner and containment coating applications
• Building and facility restoration: Surface prep of structural steel, metal panels, and architectural elements for long-term recoating performance

Shop Blasting vs. Field Blasting

Shop Blasting — Our Shelbyville and Grand Rapids Facilities

When components can be transported to our facilities, shop blasting offers a fully controlled environment for optimal surface preparation. Our skilled teams use advanced material handling equipment to manage tanks, vessels, structural and architectural steel, specialty fabrications, pipe spools, and high-volume part finishing runs. Blast media is contained and recycled, environmental conditions are controlled, and inspections are straightforward, ensuring every substrate is prepared precisely to specification and ready for coating.

Field Blasting — On-Site Expertise at Your Facility

For immovable infrastructure such as large tanks, in-service vessels, piping systems, and building structures, BlasTek brings mobile sandblasting solutions directly to your site. Our field teams deploy portable blast pots, compressors, media, containment systems, and all required PPE to safely execute projects under real-world conditions. We integrate dust suppression, containment, and environmental compliance measures while applying the same technical rigor and precision as in our shop. By combining state-of-the-art blasting methods with advanced construction practices, BlasTek handles complex, technically challenging projects that many contractors avoid.

This dual approach ensures that whether in-shop or on-site, every asset receives specification-driven surface preparation for maximum coating performance and long-term durability.
