VIAZA Limestone Grey – Polished Finish
A surface with natural character.
The polished finish brings out the refined character of VIAZA Limestone Grey, transforming its balanced grey tones into a smooth architectural surface. Precise polishing creates an elegant sheen that enhances subtle mineral variation and interacts beautifully with surrounding light. It can be considered for interior floors, wall cladding, staircases, reception areas, and distinctive architectural spaces, subject to confirmation of the selected format and application requirements.
