EaCo Chem NMD 80

The #1 Specified New Masonry Detergent in North America!

NMD 80 is a powerful detergent-based solution designed for safe and effective removal of mortar smears and efflorescence from masonry surfaces. It can be used on all masonry substrates including brick, stone, synthetic stone, precast concrete, designer or colored block. It works great to remove polymeric sand haze.

The added buffering ingredients allow NMD 80 to be powerful yet safe enough for glass and anodized aluminum. NMD 80 is a masonry cleaner that requires no respirator when working outdoors, preventing unnecessary fines. This product is capable of extremely effective cleaning and efflorescence removal without brushing or scrubbing and will leave the cream on the mortar joints.

Proper usage is essential to experience the great reductions that are possible in chemical costs and cleaning time. NMD 80 is designed to be used with the EC Jet downstream chemical injector to produce excellent cleaning results consistently, easily, and faster than ever before. Combine these cost reductions with heightened safety, excellent final appearance and a dramatic reduction in post cleaning stains and you have tomorrow’s chemistry today!

Always test prior to beginning full-scale cleaning operations. Pre-testing will determine suitability and effectiveness on each type of surface and stain designated to be cleaned. Pre-testing will also determine dwell times and number of applications required to achieve desired results. Pre-testing will show any potential or adverse reactions to adjacent surfaces. Allow test areas to thoroughly dry before evaluating final appearance and results
