Labrador Scuro Speziale should be sealed after installation, particularly on kitchen worktops and dark floor areas. At 0.2 % water absorption the stone is dense, but the sealer makes cleaning and care easier still.
For cleaning and care, pH-neutral natural stone cleaners, water and a soft microfibre cloth are sufficient. On polished surfaces, water and limescale marks should not be allowed to dry on, so that the shimmer effect stays clear.
Avoid strongly abrasive pads and aggressive special cleaners without approval for natural stone. Oil, coffee and colouring agents should be removed promptly from worktops, even though the stone is technically very robust.
Outdoors, regular cleaning, a suitable choice of finish and clean drainage all help. The weather is not the problem; soiled textured surfaces that visually swallow the shimmer are.
