Why might sandblasting be preferred over grinding for rust removal?

Sandblasting is often preferred for rust removal because it effectively covers a larger area quickly and evenly. This method utilizes high-pressure air and abrasive materials to propel particles against the metal surface, which allows for a swift and consistent removal of rust and paint. The broad coverage capability makes sandblasting an efficient choice, especially for larger surfaces or complex shapes where grinding may be more labor-intensive and time-consuming.

In contrast, grinding tends to be a more focused approach suited for precision work or smaller areas, but it generally requires more time and physical effort to achieve similar results over larger surfaces. The uniformity achieved through sandblasting minimizes the risk of uneven areas that could occur with grinding, ensuring that the rust is thoroughly addressed across the entire surface area. This makes sandblasting particularly advantageous for projects where time efficiency and thoroughness are critical.
