The wet sandblasting kit from Water Cannon Inc. - MWBE is designed to remove unwanted surface contamination such as rust, scale, loose paint, barnacles and debris. The sand and high-pressure water work together using venturi siphon technology to more safely clean metals, concrete and other similar surfaces. The kit quick-connects to the end of a commercial pressure washer wand and works on 3,000 up to 6,000 psi systems. It automatically draws sand through a 26-foot, reinforced, lightweight feed hose using an engineered self-venting pickup tube. The venturi siphon technology eliminates the need for an air-feed system or other heavy and bulky equipment. 800-333-9274; www.watercannon.com.
