01Overview
Fine Quartz Sand for Interior Coarse Putty
Fine Quartz Sand (for interior coarse putty, 80–120 mesh) serves as a dedicated rigid skeletal aggregate for interior coarse leveling putty. It markedly enhances the hardness and wear resistance of putty, effectively reduces shrinkage and cracking risks during thick-layer application, improves sanding smoothness, and cuts formulation costs. Due to its relatively coarse particles, it is suitable only for base-level coarse leveling and must not be used in mirror-surface putties. The recommended dosage is 8–20%, with strict control over mud and iron impurity content.
