Description: NMD 80 (New Masonry Detergent) in 5 gallons is a powerful detergent-based solution for commercial pressure washing equipment. This formula is specially designed for safe and effective removal of mortar smears, efflorescence, and polymeric sand haze from all masonry surfaces including brick, stone, synthetic stone, precast concrete, designer or colored block. Thanks to added buffering ingredients, NMD 80 can even be used to safely clean glass and anodized aluminum. A respirator is not required to use NMD 80 outdoors and cleans via a simple spray on/spray off process that doesn't involve brushing or scrubbing. This makes every job much safer, faster, and leaves a polished post-clean appearance that sustains repeat business.
