Pietra Cardoso is a natural stone, fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock with a pale grey to light blue background and consistent pattern throughout its surface including veins in darker and lighter blue tones which are characteristic of this popular and extremely hard wearing stone.
Pietra Cardoso is frequently used provide an organic look to any architectural area without having to incur in high costs on a project, working well as match-and-mix element in combination, by bringing the beauty of natural stone to interior or exterior surroundings including kitchens, bathrooms, living rooms, utility rooms and terraces, balconies and patio floorings.

Use of a neutral PH cleaner such as Lithofin Power Clean, for regular maintenance will protect the surfaces and ensure that no chemical damage takes places to both the stone the surface sealant that has been applied to the stone during its installation process.
