EaCo Chem NMD 80™ Masonry Detergent
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, pre-cast 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 a downstream 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!
Dilutions:
NMD 80™ is diluted 4 parts water to 1 part NMD 80™. A downstream injector is recommended to ensure both proper dilution and application of NMD 80™. Ideal size of pressure washer for exterior clean: gas powered ranging from 3 to 6 gallons per minute pressure washer not to exceed 3,000 P.S.I.
Application Instructions:
Low Pressure Application
1. Lightly pre-wet or flash-cool the surface (do not soak).
2. Apply NMD 80™ through a downstream injector to the entire section to be cleaned. Start from the top and work down. Allow NMD 80™ to dwell for 5-7 minutes.
3. After the initial application of chemical, scrape the large chunks of mortar with a long-handled scraper.
4. Check mortar smears and tags to see if it crumbles easily.
5. Reapply NMD 80™ without rinsing between applications to melt the remaining mortar residue and extend dwell time. Once there is no foaming, the surface is ready to be rinsed.
6. With NMD 80™, the longer it stays wet on the wall, the cleaner the end result. This will also reduce the amount of rinsing required. After reapplication, scraping can be done further down the wall.
Coverage Rates:
Coverage rates with NMD 80™ using a downstream injector will vary from 100-200 sq. ft. per gallon depending on the surface porosity, texture, ambient temperature, craftsmanship, severity of mortar smears, and severity of other post construction staining.
Rinsing:
Proper rinsing techniques determine the final look and quality of the job. Generalized rules of rinsing would include:
1. Low-pressure rinse. The downstream injector can be used as long as the ball valve to NMD 80™ has been turned to the off position.
2. If using a pressure washer to rinse use a 40-degree nozzle is reduce the potential for surface damage. Stay at least 8”-12” from the wall to avoid potential damage to the mortar joints. Do not use a zero-degree nozzle.
3. Craftsmanship determines the appropriate pressure for rinsing. A thorough rinse job is recommended; however, our chemistry never requires flooding a wall. Pressures that mark or damage the surface should be avoided. When in doubt, follow the manufacturer’s recommended P.S.I. for the substrate you are working on.
4. Always use overlapping horizontal passes to achieve a uniform appearance.
