Viaza Limestone
Viaza Grey Light Bush-Hammered
Refined Grey limestone in a light bush-hammered finish.
VIAZA Limestone Grey – Light Bush-Hammered Finish
A surface with natural character.
The Light Bush-Hammered finish enhances VIAZA Limestone Grey through a finely textured surface that adds subtle depth while preserving the stone’s soft grey tones and mineral variation. The delicate mechanical treatment creates a refined relief and naturally matte appearance. It can be considered for terraces, walkways, pool surrounds, façades, staircases, and contemporary spaces, with application-specific performance confirmed against current technical documentation.
