Yellow Niwala – Sandstone

Category: Tags: , ,

Niwala yellow sandstone is a yellow sedimentary stone that characterizes its texture.

Its golden finish and natural grain give the works and elements that make it a natural elegance inimitable by other artificial materials.

To be taken into account its anti-slip capacity, as well as the ease of cleaning, as it can be applied anti-graffiti and self-cleaning treatments.
