On-Site Perfection: A Technical Guide to Stone Repair and Patching
This technical guide establishes a professional standard for natural stone repair and restoration, prioritizing project margin protection through “Repair Science.” We evaluate the decision matrix between repair and replacement using the 50% cost rule and detail advanced color-matching techniques using mineral pigments and mica powders. The report emphasizes how 95% hue uniformity and same-batch quarry consistency enable invisible, factory-grade repairs. From pH-neutral mortar haze removal to CNC-standard precision cutting, these protocols ensure structural and aesthetic continuity for large-scale architectural facades through 2026.
