Surface Prep: Before & After Blasting

Updated: December 22, 2023

If you're running a business in manufacturing or industrial sectors, abrasive blasting should be a key part of your daily operations. While the term "sandblasting" is still used, it's important to note that modern processes rarely use actual sand anymore. Instead, the focus is on surface preparation, which is essential for ensuring proper adhesion and long-lasting results.

Abrasive blasting plays a crucial role in preparing surfaces for coatings, whether it's paint, powder, or other finishes. It not only helps improve the appearance of the final product but also enhances its durability and performance. Without proper surface prep, even the best coatings can fail prematurely, leading to costly rework and maintenance.

The Importance of Proper Surface Preparation

One of the main reasons to prioritize surface prep is that skipping this step can lead to poor adhesion. Whether you're applying paint, sealants, or protective coatings, the finish won’t look good or last long without a properly prepared surface. A weak bond between the coating and the substrate can result in peeling, flaking, or blistering, which not only looks unprofessional but also reduces the lifespan of the product.

Starting with a clean, well-prepared surface ensures better aesthetics and improved functionality. This is especially important for parts that are exposed to harsh environments or heavy use. At Finishing Systems, we understand the value of precision and quality in every step of the process.

Sandblasting vs. Abrasive Blasting

Although the terms "sandblasting" and "abrasive blasting" are often used interchangeably, the latter is more accurate today. Sandblasting was historically common, but due to health and safety regulations around silica dust, it’s now less frequently used. Today, abrasive blasting refers to a broader range of materials and methods, each with unique properties and applications.

We offer a wide variety of blast media, including Starblast, Glass Beads, Aluminum Oxide, Silicon Carbide, Plastic Abrasives, and natural options like Corn Cob and Crushed Walnut Shells. Each media type has different grit sizes and characteristics, allowing us to tailor the process to your specific needs.

There are also multiple blasting techniques available depending on your budget, equipment requirements, and application:

  • Air Blast Equipment
  • Centrifugal Wheel Blast Equipment
  • Blast Cabinets and Portable Units

Our team is here to help you choose the right media and equipment for your project. Let us guide you toward the most effective and efficient solution.

Cleaning After Blasting

Once the blasting is complete, it’s important to keep the surface clean and free from contaminants. If left untreated, iron-based substrates can quickly rust, especially if the next step in the finishing process isn't done promptly. In some cases, using rust inhibitors can help protect the surface until the finish is applied.

Always ensure that your blasting media is clean and dry. Contaminated or wet media can reduce efficiency and compromise the quality of the surface prep.
