Surface Preparation: Before and After Blasting
Last Updated: December 22, 2023For businesses operating in the manufacturing or industrial sectors, incorporating abrasive blasting into your regular processes is crucial. Although the term "sandblasting" is still commonly used, it's important to note that modern abrasive blasting rarely involves actual sand. Surface preparation is a critical step in achieving optimal results from this process.
Abrasive blasting ensures that surfaces are adequately prepared for subsequent coatings, and in certain scenarios, it can even deliver the final finish. If you're looking to enhance your product quality while streamlining operations, contact us today to explore how we can assist.
The Critical Role of Proper Surface Preparation
Including surface preparation in your blasting routine is essential because skipping this step can lead to poor adhesion of finishes. Whether you're painting or applying another type of finish, the end result will only be as good as the preparation work done beforehand.
Without proper surface preparation, coatings such as paint or powder may fail to adhere correctly, often resulting in premature failure and the need for costly rework. Starting with a well-prepared surface ensures that your components look great and function effectively.
Understanding Sandblasting Surface Preparation
Both "sandblasting" and "abrasive blasting" refer to similar processes, though the former term has fallen out of favor due to health and safety concerns surrounding silica sand. The broader term "abrasive blasting" better reflects the variety of materials that can be used in this process, each offering unique characteristics and outcomes. Selecting the right abrasive is key to achieving your desired results—let our team guide you through the options tailored to your specific needs.
A wide array of blast media is available, including popular choices like Starblast, glass beads, aluminum oxide, silicon carbide, plastic abrasives, steel shot, corn cob, and crushed walnut shells. These materials come in various mesh or grit sizes to achieve different finishes and effects.
Depending on your budget, equipment requirements, and particular application, several blasting methods are available:
- Air blast systems
- Centrifugal wheel blast systems
- Blast cabinets and portable units
Our team is here to help you select the ideal equipment to meet your surface preparation goals. 
Cleaning the Surface Post-Blasting
Proper surface preparation leaves your substrate ready for the next stage of finishing while maintaining a raw state. Ensure you're prepared to apply your chosen finish promptly to avoid rust formation. Iron-based substrates or alloys containing iron can rust quickly, so consider using rust inhibitors if immediate finishing isn't possible.
Keep your abrasive clean and dry to maintain effectiveness during blasting operations.
