1) Good finish
2) Extraordinary hardness
3) Even hardness (8)
4) High content of silica
5) Good value for money
Its hardness extraordinary prevents cutting mechanical being and the manual finish the blocks are finished so that the faces are the most perfect as possible to achieve less holes in the joints between them, thus significantly increases the life of the coating.
