White 5L Diatom Mud for Coating Painting - High Coverage for Interior and Exterior Surfaces
Product Overview
White 5L Diatom Mud Coating is a premium interior/exterior wall finish formulated with 85% natural diatomaceous earth, engineered to deliver unmatched coverage (15–20 m²/L), breathability, and environmental safety. Combining the porous structure of fossilized diatoms with advanced binding polymers, this coating actively regulates indoor humidity (±5% RH fluctuation control), absorbs VOCs (e.g., formaldehyde, benzene), and resists mold growth—making it ideal for hospitals, schools, and eco-conscious residential projects. Certified zero-VOC (SGS Test Report: <2 g/L) and fire-retardant (ASTM E84 Class A), it outperforms conventional paints in durability, aesthetics, and sustainability.
