For the extra-tough cleaning jobs, wet-sandblasting is the dust-free solution. Landa’s sandblasters attach to a hot or cold water pressure washer and, using a venturi, mixes sand or other abrasive media with the high-pressure spray to create enough cleaning power to strip paint off concrete and barnacles from a ship’s hull. The sandblasting nozzle is made of tungsten carbide for long life. There are two models—a top-of-the-line steel pot (photo at right) with tight-fitting lid or with a probe only.
