Pic.1 Each grain is micro encapsulated with water, held on by surface tension. This increases the mass of the grit to increase the hitting power. It also files as a perfect sphere in the air flow, increasing the speed and is lubricated to almost eliminate hose and nozzle wear.
|
Pic.2 BANG! the grit stops dead, embedding in the surface coating. The water jacket continues moving but still holding onto the grain by surface tension, giving a second hammer blow and stopping any grit bounce .
|
Pic.3 BANG! the water jacket jerks round the grit into the crack, under the coating and hydrostatically blasts a large amount of surface coating away.
|
| Pic.4 The end result – a profiled surface, feathered edges and the most efficient use of the least amount of grit and water possible. |
