Water Blasting Technology: Applications & Media Selection Guide

Exploring the Versatility and Benefits of Water Blasting in Modern Surface Treatment: A Comprehensive Guide to Applications and Media Selection

1. Introduction: Why Water Blasting?



Water blasting (Wet Blasting) combines abrasive media with a controlled water stream, offering dust-free operation, better surface quality, and reduced material damage compared to dry blasting. It is widely used in aerospace, automotive, medical, and precision manufacturing for eco-friendly and high-precision surface treatment.
