As a Turkish sedimentary limestone, Miros Typ Myrddin® is acid-sensitive and markedly more maintenance-intensive than granite or quartzite. With a Mohs hardness of 3–4, medium water absorption and pronounced acid reactivity, the stone calls for deliberate care and consistent sealing. These notes should be consciously taken into account in the material choice — limestone is a deliberately chosen design material, not a maintenance-free all-rounder.
For internal applications we recommend careful sealing on a silane or polysiloxane basis at first installation, applied in two coats for sufficient penetration depth. The finishes currently available from stock are listed in the »Finishes« block further down this page. Sealing protects against deep penetration of oil, grease, pigments and water stains — otherwise discolouration can settle visibly on the light creamy ivory groundmass.
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 limestone immediately and leave matt etch marks that can only be removed by professional regrinding. Cola, wine, tomato sauce and citrus fruits can likewise leave etch marks on untreated surfaces — take up spillages immediately. Particularly important in bathrooms: remove water and soap residues regularly, because soap residues left to act for longer can permanently reduce the gloss.
For kitchen worktops, Miros Typ Myrddin® is only conditionally suitable — it is not fully acid-resistant and not fully resistant to cutting and scratching (Mohs hardness 3–4 vs. 7+ for granite/quartzite). Heat resistance is given, but hot pots 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, Miros can be very effective with good care — particularly for modern minimalist concepts or wabi-sabi stagings with a conscious acceptance of patina.
For bathrooms and wellness areas, Miros Typ Myrddin® is a very fitting choice — the calm light material effect brings the typical spa atmosphere. Important here: where there is direct water loading (shower walls, bath surrounds, vanity tops), particularly careful sealing is obligatory, and acidic sanitary cleaners are strictly to be avoided. The finishes currently available from stock are listed in the »Finishes« block further down this page.
For external applications we recommend Miros Typ Myrddin® only with restrictions. Turkish light sedimentary limestones sometimes show discolouration or fine surface splitting under freeze-thaw cycles and intensive UV exposure. Before external applications, in particular large-area façades or pool areas, we recommend a project-related check of the data sheet for frost resistance with the importer. For interior-oriented applications, light, calm material effects such as those of Miros Typ Myrddin® are the ideal domain of use.
