As an Indian granulite, New Colonial Dream is a robust hard rock with low water absorption (typically 0.1-0.3 %), good acid resistance and a Mohs hardness of 6-7. Wine, lemon juice, vinegar, cola, sanitary cleaners or descalers leave no etch marks as they would on marble or limestone.
For interior applications we recommend an impregnation on a silane or polysiloxane basis at initial installation. On polished surfaces, 5-10 years can pass between impregnation renewals depending on use; on heavily used kitchen worktops or in external applications, check every 2-3 years. Impregnation protects against the deep penetration of oil, grease and pigments — otherwise, discolouration can show up visibly on the lighter creamy yellow areas.
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 are fundamentally unproblematic, but should nevertheless not be used, because they can attack the impregnation. The finishes available from stock are listed in the »Finishes« block further down.
For kitchen worktops New Colonial Dream is very well suited: cut- and scratch-resistant, insensitive to heat (hot pots and pans can be set down directly for a short time, although prolonged heat exposure above 200 °C should still be avoided), acid-resistant and with good stain repellency. The warm golden surface conceals small traces of use remarkably well. For external applications, with its low water absorption New Colonial Dream is frost-resistant and stable in the long term against the weather — outstandingly suited to external façades, terraces, staircases and pool areas. The finishes available from stock are listed in the »Finishes« block further down.
For pool surrounds, external terraces and fountain settings a slip-resistant structured finish is mandatory — on smooth external surfaces there is a high risk of slipping when wet. In areas with frequent salt contact (de-icing salt, pool chlorine) we recommend an additional annual renewal of the impregnation.
