Hatch Finishes


Chiselled finish

This classic masonry technique involves incising the limestone surface with a series of parallel thin lines. These rows of incisions in the limestone appear dark grey or black set against the smooth curved surfaces of the stone. The chiselled finish achieves a paler blue-grey colour with the ancient crinoids revealing themselves as a randomly distributed pattern of paler grey flecks. Chiselled blue limestone is an excellent finish for both internal and external applications such as cladding, ashlar, lintels, mouldings, pavilions, setts, kerbs and steps.


Old Mechanical Chiselled

The Old Mechanical Chiselled finish typically gives the Irish limestone an overall light-grey appearance with the light-grey markings directly contrasting with the darker limestone background. This finish has its origins in the type of manual cuts once administered by stonemasons to the rough surface of limestone using a flat chisel with 20 to 30 strokes per 100mm. The grooves are intermittent and mostly run either parallel to the edges or at a 45° angle. This artisan finish is extremely popular as a feature on paving and cladding.



The Sbattu finish consists of light-grey markings applied against a darker limestone background. Similar to the Old Mechanical finish, the chisel grooves are intermittent, yet somewhat deeper and are mostly applied at an angle of 90°. The finish is used mainly applied on external stonework surfaces, such as cladding and paving.
