This is a smooth, pale blue-grey finish that results from a dry sanding process. The natural features of crinoids and the calcite grain structure are visible, showing off minor tonal variations. The ground faces are flat with a faint, fine pattern of scores. It is a specific finish to Irish blue limestone, and is ideal for a variety of uses, both internal and external. The sanded dressing has been used to great effect on the external cladding of a number of influential building projects and is considered to be one of the most characteristic and appealing finishes applied to Irish blue limestone.
