As a Chinese granodiorite, Padang TG33 Hellgrau is a robust hard stone with low water absorption (0.35 %), full frost and acid resistance and solid mechanical strength. Wine, lemon juice, vinegar, cola, sanitary cleaners or descalers leave no etch marks as they would on marble or limestone — the stone is considerably easier to look after and well suited to intensive everyday use.
For interior applications we recommend a silane- or polysiloxane-based impregnation at first installation. On the pale groundmass, impregnation is worthwhile, because pigments can otherwise settle more visibly. On polished surfaces a refresh every 8–10 years is enough; on heavily used floor areas or in exterior applications, check every 3–5 years.
Day-to-day care is done with a pH-neutral natural stone cleaner and a soft cloth or microfibre mop. Clear warm water is usually enough. Acidic cleaners are in principle unproblematic, but should nevertheless not be used, because they can attack the impregnation. The surface finishes available from stock are listed in the »Finishes« block further down.
For kitchen worktops Padang TG33 Hellgrau is solidly suited: cut- and scratch-resistant (Mohs hardness 6–7), insensitive to heat (hot pots and pans can be set down directly for short periods, but longer heat exposure above 200 °C should still be avoided), acid-resistant and with good stain repellency. The pale salt-and-pepper surface does, however, show sauce, red wine or turmeric stains more strongly than dark granites — with intensive kitchen use you should react promptly.
For exterior applications Padang TG33 Hellgrau is well suited: the low water absorption and the typical strength of a Chinese granite qualify the stone for exterior façades, paving, pool areas and applications exposed to frost and de-icing salt. The surface finishes available from stock are listed in the »Finishes« block further down.
For pool surrounds, outdoor terraces and fountain enclosures, a slip-inhibiting textured finish is mandatory — on polished exterior surfaces there is a high risk of slipping when wet. In areas with frequent salt contact we recommend an impregnation refresh every 2–3 years.
