Protective coatings are often recognised as the first line of defence against corrosion, helping industries extend asset life, improve reliability, and reduce long-term maintenance costs. Yet, before any coating system can perform as intended, one critical process must be completed correctly—surface preparation.

At the centre of that process are skilled sandblasters.

Every bridge, offshore platform, refinery, pipeline, storage tank, wind turbine, ship, and industrial structure relies on proper surface preparation before a protective coating is applied. The quality of this work directly influences coating adhesion, corrosion resistance, and the long-term performance of the asset.

Despite its importance, abrasive blasting is often misunderstood as simply removing rust or old coatings. In reality, it is a highly skilled profession that demands technical knowledge, precision, and experience.

Professional sand blasters must understand abrasive selection, blasting equipment, nozzle techniques, surface cleanliness standards, anchor profile requirements, environmental conditions, and project specifications. Every decision made during the blasting process contributes to the overall success of the coating system.

Across the corrosion protection industry, coating failures are frequently linked to inadequate surface preparation rather than coating performance alone. This reinforces an industry principle that coating professionals have long understood: the quality of a coating system begins with the quality of the prepared surface.

Yet the work of sandblasters often goes unnoticed. Once blasting is complete, the prepared surface is covered by primers and protective coatings, leaving little visible evidence of the expertise required to create it. Although hidden from view, that work continues to protect assets for years.

Recognising the value of this profession is the purpose of International Sand Blasters Day, observed annually on 24 July. The initiative encourages the coatings and corrosion control industry to acknowledge the professionals whose knowledge and craftsmanship provide the foundation for every successful protective coating system.

International Sand Blasters Day also promotes greater appreciation for professional training, safety, technical excellence, and the vital contribution sand blasters make across industries, including marine, oil and gas, infrastructure, manufacturing, mining, power generation, and heavy engineering.

Every long-lasting coating begins with a properly prepared surface.

Behind every properly prepared surface is a skilled sand blaster whose contribution deserves recognition not only on 24 July, but throughout the year.
