BUSH HAMMERED SLATE
The treatment is performed using pneumatic tools (bush hammer) to continuously impact the rock, providing an old stonework finish or bush hammered surface. The surface has small craters uniformly distributed between 1 and 3 mm deep, lightening the colour of the granite.
Depending on the force applied, number of impacts and the type of head used, a finish with a different size and density of speckles can be obtained.
