Steel Blast Cleaning in Austin, TX
Ace Sandblasting has delivered certified steel blast cleaning across Texas since 1972. Every coating system applied to steel is only as reliable as the surface beneath it. We work to SSPC and NACE standards, document the results, and coordinate directly with coating applicators and project engineers.
Why the Blast Standard Matters
A coating applied to a properly blasted surface and one applied to an improperly blasted surface look identical on day one. The difference shows up later, and by then the cost of remediation has already multiplied.
Selecting the wrong standard for the coating system is one of the most common and costly specification errors on steel projects. We review specs with clients, advise when needed, and deliver the cleanliness level the coating manufacturer requires.
SSPC and NACE Blast Standards We Work To
White Metal Blast: SSPC-SP5 / NACE 1 SA3
The highest level of steel cleanliness achievable through abrasive blasting. No visible rust, mill scale, coatings, or contaminants remain. Specified for immersion service, chemical exposure, severe corrosion conditions, and high-performance coating systems that require a completely clean substrate.
Near-White Metal Blast: SSPC-SP10 / NACE 2 SA2.5
The most commonly specified standard for heavy industrial and infrastructure projects. No more than five percent of each unit area may retain light shadows or stains from rust or mill scale. Specified for offshore structures, bridges, industrial plants, tank exteriors, and structural steel in high-corrosion environments.
Commercial Blast: SSPC-SP6 / NACE 3 SA2
Specified for steel in moderate-exposure environments. Staining is permitted on no more than 33 percent of each unit area. Suitable for a broad range of industrial and architectural coating systems. The standard Ace delivers across the widest range of structural steel, equipment, and building component projects in Central Texas.
Brush-Off Blast: SSPC-SP7 / NACE 4 SA1
Removes loose rust, mill scale, and loose coatings while allowing tightly adhered material to remain. Used in maintenance situations, overcoat preparation, and where the specified coating system does not require full surface cleanliness. This is a precise specification, not simply a fast pass with the equipment.
Additional Services
Rust Grade B Pre-Blast Treatment
Steel with beginning-to-moderate surface rust requires rust grade assessment before blasting begins. This affects media selection, blast duration, and the achievable surface profile. Skipping this step leads to specification failures that only appear after the coating is already applied.
Full Steel Surface Preparation
Surface assessment, pre-blast treatment where required, blasting to the specified standard, surface profile verification, and documentation. The surface is ready for coating when we leave the site.
Metal Sandblasting
Structural steel, fabricated components, process piping, storage vessels, equipment, and architectural metalwork. Single components to multi-structure facilities. We have the equipment and crews to handle the scope.
24/7 Availability
Blasted steel can begin to flash rust within hours in humid or high-temperature conditions. Coordinating blast work with the coating application window is critical. Ace Sandblasting is available around the clock, every day of the year, for scheduled and emergency steel blast cleaning.

Frequently Asked Questions
1. What is the difference between SSPC and NACE blast cleaning standards?
SSPC and NACE developed parallel steel surface cleanliness standards that have since been jointly adopted. SSPC-SP5 corresponds to NACE 1 SA3, SSPC-SP10 to NACE 2 SA2.5, SSPC-SP6 to NACE 3 SA2, and SSPC-SP7 to NACE 4 SA. 1. The standard specified on your project may reference either or both designations. Ace Sandblasting works on all four grades.
2. How do I know which blast standard my project requires?
The blast standard is determined by the coating manufacturer's application requirements and the project engineer's specification. Immersion service and severe environments typically require SSPC-SP5 or SSPC-SP10. Atmospheric exposure in standard conditions often calls for SSPC-SP6. Maintenance overcoat projects may specify SSPC-SP7. We review project specifications with clients and can advise when required.
3. Can you provide documentation of the blast standard achieved?
Yes. For projects that require it, we provide blast inspection records, surface profile measurements, and cleanliness verification documentation. This is standard practice on structural steel, industrial, and infrastructure projects where coating warranty or contract compliance requires it.
4. What is rust grade B and why does it matter before blasting?
Rust grade B describes a steel surface with beginning-to-moderate surface rust and light scale. Rust grade B pre-blast treatment ensures the correct media type and blast approach are selected for the specific surface condition. It affects the achievable cleanliness level and surface profile.
5. What is brush-off blast cleaning used for?
Brush-off blast cleaning SSPC SP7 is used in maintenance coating situations where tightly adhered existing coatings are retained, for overcoat preparation, and on projects where the coating system doesn't require a higher cleanliness grade. It's a precise standard, not simply a light pass with abrasive equipment.
6. How quickly can blasted steel develop flash rust?
Freshly blasted steel can begin to flash rust within hours in humid or high-temperature conditions. Coordinating blast work with the coating application window is critical. Our 24-hour availability is specifically designed to support tight coating windows when weather or schedule requires overnight or early-morning blast prep.
7. Do you offer free estimates for steel blast cleaning projects?
Yes. Contact us at (512) 712-8229 for Austin-area projects or (210) 212-5711 for San Antonio. We assess surface condition, specified blast standard, surface area, access requirements, and project schedule before providing a detailed estimate at no charge.
8. Do you serve clients outside of Austin?
Yes. Ace Sandblasting operates in Austin, San Antonio, Dallas, and Corpus Christi and can mobilize for large-scale steel blast cleaning projects throughout Texas. Call (512) 712-8229 or visit acesandblasting. Call for more information.
