Wholesale Stone Efflorescence Control: Factory QC & Installation Standards for B2B Projects
Efflorescence remains a critical risk to masonry integrity and project ROI. This technical guide outlines a multi-stage Quality Control (QC) framework to eliminate mineral salt migration, starting with Top Source Stone’s proprietary thermal-extraction factory washing. We analyze the mechanics of capillary wicking and provide rigorous standards for substrate pH testing (ASTM D4262) and back-sealing protocols. By shifting from reactive cleaning to factory-level prevention, B2B contractors can ensure 95% hue uniformity and long-term facade stability in high-humidity environments.
