MARMORINO NATURALE FINE

OIKOS PAINTS: MARMORINO NATURALE FINE 

Marmorino Naturale Fine is the finer-grained variant of Oikos’s lime putty-based decorative plaster range, sharing the same slaked lime, marble grain, and mineral pigment composition as Marmorino Naturale but with a maximum grain size of 0.3mm compared to 0.8mm. This finer texture produces a smoother, more refined surface that is particularly suited to polished marble effects when finished with Finitura Autolucidante, while still delivering the full breathability and natural mould resistance of a traditional lime plaster. Like its coarser counterpart, it is suitable for both interior and exterior walls on historical and prestigious buildings, and its lower yield (1 to 1.5 kg/m² versus 2 kg/m²) means less material per square metre for a thinner, more elegant finish. The alkaline lime matrix (pH 12.5 to 13.5) naturally suppresses mould and bacterial growth without chemical additives, and the formulation remains free from heavy metals, toxic solvents, and aromatic compounds.

Sustainability Features

• VOC content 14 g/L, certified per EU Directive 2004/42/CE Class A/a, more than 50% below the Phase II regulatory limit of 30 g/L
• Natural lime putty base with mineral fillers, avoiding synthetic polymer binders
• Free from lead, chromium, toxic solvents, aromatic compounds, and chlorides
• High vapour permeability (Class V1, Sd = 0.08m) preserves the breathability of the full wall structure, supporting healthy moisture regulation indoors and outdoors
• Alkaline lime matrix naturally inhibits mould and bacterial growth without chemical biocides
• Non-inflammable with Euroclass B-s1,d0 fire rating (limited smoke, no flaming droplets)
• Low odour formulation reduces occupant disruption during and after application
• Water-based system with water tool cleanup, eliminating solvent use on site
