Nuvolato Calacatta is an acid-sensitive marble. Wine, lemon juice, vinegar, cola, sanitary cleaners or descalers leave etch marks on the material surface — visible as dull shadows or loss of gloss. On a pale marble with such a fine vein figure, changes of this kind are visually particularly conspicuous.
For all applications, a silane- or polysiloxane-based sealer is essential. It prevents the ingress of water, oil and colouring agents and reduces staining — but it does not remove the acid sensitivity. We recommend refreshing the sealer every 1-2 years. On pale marbles the sealer is doubly important: a single drop of olive oil or red wine that seeps through can remain as a permanent dark stain.
Daily care is carried out with a pH-neutral natural stone cleaner and a soft microfibre cloth. Avoid vinegar cleaners, cement haze removers, acidic sanitary cleaners and strongly alkaline products. Wine, coffee, oil, lemon juice or coloured cosmetic products should not be left to act for long on polished surfaces — wipe off immediately and wipe over with clear water.
For kitchen worktops, Nuvolato Calacatta is only conditionally suitable. Anyone who wants the iconic Calacatta look in the cooking area and accepts patina as character can use the material — but acids from everyday cooking will leave visible marks. Anyone who needs maximum everyday security should choose a pale quartzite such as Chantilly.
The material is not suitable for permanently weathered external surfaces. Indoors it is stable over the long term with proper care.
