The Polished finish is appears a dark, blue-grey to black colour depending on the bed being processed. Fossil traces, white spots, calcite veining will all show up early on the surface. Polished finishes are applied to large slabs using a rotating head equipped with soft slightly abrasive pads. A continuous supply of water washing across the surface and random oscillation of the head gives the deep lustrous finish. The Polished finish is most often used for internal cladding, steps, sills, skirtings and floor tiles. It is also used in furniture, pedestals, tops for vanity units and counters.
The smooth and even appearance rendered by the blue honed finish is achieved through the use of a range of grits. When a honed finish is applied to Irish blue limestone, the coarseness of the grit used will directly impact the colour of the final finish. The coarsest grit (100) achieves a pale blue-grey colour and produces a smooth and matt texture with a faint pattern of circular scores. Honed finishes are suitable for interiors such as worktops, flooring and cladding but are also used externally for furniture, window sills and plinths.
The smooth and even appearance rendered by the dark honed finish is achieved through the use of a range of grits. When a honed finish is applied to Irish blue limestone, the coarseness of the grit used will directly impact the colour of the final finish. The finest grit (500) will achieve a dark blue-grey to black appearance. Crinoids are revealed as well-defined surface mottling, with finely honed shell beds often appearing black with a spectacular white contrast provided by the brachiopods and other sea life. The level of grit used will also affect the texture of the finish. Finer grits (300 and 500) produce a smooth matt texture. Honed finishes are suitable for interiors such as worktops, flooring and cladding.
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.
