Petit Granit: complete guide

History and origin

It comes from Belgium, particularly Wallonia, where it is also known as bluestone. It is a limestone made up of fragments of marine organisms, mainly crinoids, whose granular appearance suggested the trade name 'little granite'. For centuries it has been one of the most widely used materials in Belgian and Northern European architecture. Marmi di Carrara supplies it on request.

Look and veining

The background is dark blue-grey speckled with light fossil fragments and small white veins. Slabs vary in fossil density and the presence of veins. Polished, it becomes almost black and brilliant; honed, it is blue-grey, while bush-hammered or flamed it lightens towards grey.

Technical properties (indicative)

Recommended uses

Widely used for floors, stairs, thresholds, window sills, façades and outdoor paving, even in cold climates. In the kitchen it is possible, but you should bear in mind that acids and citrus fruit leave light marks.

Care and maintenance

Clean with neutral products and treat with a stain-proofing product; outdoors a water repellent limits dirt and moss. Avoid anti-limescale and acidic products.
