Silestone is made of more than 90% pure quartz. Quartz is incredibly hard and durable. It is non-porous with a texture that does not allow bacteria to grow and very resistant to cracks and stains. It will not require sealing or resealing. Quartz worktops are also naturally scratch resistant. Available in more than 80 colours and different textures, it is the ideal surface for interior decoration, both for the kitchen and bathroom worktops and in other household applications.
