Blue Brushed

This finish is the result of intensive grinding of the surface with special brush-type tools.

The gallery contains real images of the ‴Blue Brushed‴ finish.

This finish is the result of intensive grinding of the surface with special brush-type tools.
The brushes consist of fine diamond particles trapped in a plastic matrix. The specific surface density of the particles determines the final blue-gray colour of the stone surface. Blue Brushed is a highly durable finish, perfectly suitable for indoor and outdoor applications.

Chemical composition

Over 98% Calcite, 0.7% Dolomite, 0.7% Quarts, 0.2% organic Carbon, Less then 0.1% Iron Sulfite

Due to its extremely low Iron composite content, Irish blue limestone is suitable for use in pressurized urban or industrial environments without risk of compromising the stone through brown discolouration or staining.
