The risk of cracking often depends on the stability of the substrate (the wall underneath). Microcement is generally highly flexible and resistant to hairline cracks. Venetian Plaster and Limewash are breathable and may develop small, natural hairline cracks over time, which often add to the “Old World” aesthetic. For repairs:

• Limewash is the easiest to repair as new coats blend seamlessly.
• Venetian Plaster and Microcement require skilled patching and re-troweling to match the surrounding texture and sheen, often necessitating a professional touch-up to maintain a seamless look.
