Paint Removal with High-Pressure Water

Spray processes with high-pressure water enable an efficient processing of the most varied metallic surfaces.

Whether it involves ships, painting cubicles or painted metal roofs: With high-pressure water, paint can be efficiently removed from metallic surfaces. With its different cleaning systems, KAMAT offers a cleaning system for all applications. High-pressure pumps can be combined with matching accessories and coordinated to the paint-removal substrate. By the use of high-pressure guns, surface cleaners and additional abrasives, KAMAT offer extensive options for removing paint with high pressure water.

Reference example: Water-sand blasting process with paint-removal and rust-removal from ships

With the water-sand blasting process, an abrasive agent is added to the high-pressure water, in order to enable efficient paint and rust removal from metallic surfaces. Dust contamination concerns mean that pure sand blasting is prohibited in many countries, or permissible only under strict conditions. Water-sand blasting is an alternative which enables the use of abrasive agents, such as sand, silica sand or ground blast furnace slag, in order to achieve different shot blasting results.

In comparison with purely abrasive agent shot blasting systems, this system has the advantage that no deformation (peening) arises in the shot blasted material. With the water-sand blasting process the heat is removed by the water so no form-changing heat concentration occurs in the shot blasted material. In addition, in case of paint removal with high pressure, the removed material is carried in the water and washed away.

In case of the water-sand blasting process, the high-pressure gun is provided with an injector, through which the abrasive additive is added to the water. With increasing operating pressure, the required quantity of abrasive agent reduces. Vice versa in comparison with pure water jets, a significantly lower pressure is required for a comparable result.
