As an Italian freshwater sedimentary limestone, Travertin Beige C-C is acid-sensitive. With a Mohs hardness of 4.5–5, moderate water absorption (0.89 %) and pronounced acid reactivity, the stone calls for deliberate care and consistent sealing. These points should be deliberately factored into the choice of material — travertine is not a granite or quartzite.
For internal applications we recommend careful sealing with a silane- or polysiloxane-based product at first installation, applied in two coats for sufficient penetration depth. The finishes available from stock are listed in the »Finishes« block further down. Sealing protects against deep ingress of oil, grease, pigments and water marks — on the pale creamy groundmass, discolouration can otherwise settle visibly.
Daily care is carried out with a pH-neutral natural stone cleaner and a soft cloth or microfibre mop. Clear warm water is usually sufficient. Acidic cleaners (vinegar, citric acid, sanitary cleaners, descalers) are STRICTLY to be avoided — they attack the travertine immediately and leave dull etch marks that can only be removed by professional re-honing. Cola, wine, tomato sauce and citrus fruits can also leave etch marks on untreated surfaces — take spills up immediately.
For kitchen worktops, Travertin Beige C-C is only conditionally suitable — it is not fully acid-resistant and not fully cut- and scratch-resistant (Mohs hardness 4.5–5 versus 7+ for granite/quartzite). Heat resistance is given, but hot pans should not be set down directly (use trivets). For intensively used professional kitchens we recommend alternative hard stones; for a warm, characterful designer kitchen with a deliberate material effect, however, Travertin C-C can be highly effective with good care — particularly for vintage, wabi-sabi or Mediterranean schemes with a conscious acceptance of patina.
For external applications, Travertin Beige C-C is frost-resistant in principle (confirmed by a strength loss of only 9.9 % after freeze cycling). A tumbled or unfilled surface is ideal for pool and external areas, because it is slip-resistant and emphasises the natural travertine character. For pool surrounds, travertine is traditionally the first choice in Mediterranean climate zones, because the stone does not store heat strongly and remains pleasant underfoot. In areas with frequent salt contact (de-icing salt, pool chlorine) we recommend an additional annual refresh of the sealer.
The question of the pores: in the 'unfilled + satin-honed' version the travertine pores remain openly visible — they can collect dirt under intensive floor use, but are easily cleaned with a soft brush. In 'filled + honed' the pores are filled with a colour-matched limestone mortar — the surface is fully smooth and easier to maintain, but under mechanical loading the filled points can show small chips over the years, which can be professionally re-filled.
