NMD 80 is a buffered acid-based new masonry
cleaner designed for cleaning mortar smears off of
new masonry structures. NMD 80 can be used on
a wide variety of substrates without harming the
surface or color when used as directed. NMD 80 is
the number one specified cleaner by brick and block
manufacturers. NMD 80 requires no scrubbing to be
effective.
Advantages
• Spray-on/rinse-off application increases production
and reduces labor when applied through an ECJet.
• Will not harm most glass or anodized window
frames when used as directed.
• Reduces water-in-wall issues, such as
efflorescence.
• No respirator required when used outdoors (other
safety precautions apply).
• One cleaner for multiple substrates, which includes
unpolished natural stone and cast stone. (see
complete list under suitable substrates)
• For use on vertical and horizontal surfaces.
• Effective way to remove large scale efflorescence.
• Biodegradable
• Top down application allows more product
coverage on lower elevations.
Limitations
• Should not be used on polished stone or limefaced brick.
• Only apply to areas to be cleaned. Product can be
corrosive to certain woods, metals, and plants.
• Avoid elevator doors as the coating will be affected
by the chemical.
• Cover any building hardware, including brass,
bronze, copper, gold, stainless or mild steel.
• Use low pressure rinsing on synthetic stone and
surface dyed substrates

Preparation
Protect adjacent surfaces and surrounding building
hardware not intended to be cleaned from exposure to
the cleaning solution. Avoid direct contact with foliage.
Cover landscape using plastic or wet the foliage with
water before and after cleaning. Avoid wind drift on
surrounding surfaces such as auto and pedestrian
traffic. Elevator doors, stainless steel hardware, and
brass coated parts should be covered. Generally,
surfaces such as glass, anodized aluminum, brick,
block, and limestone are not affected by NMD 80.
Since every surface and situation can be unique,
proper testing is required.
Surface & Air Temperatures
Excessively high or low temperatures will produce
poor results and possible harm. Best cleaning results
are obtained when air and surface temperatures are
above 40° Fahrenheit or less than 90° Fahrenheit.
Do not clean when temperatures are below freezing
or will be overnight. If freezing conditions exist,
allow adequate time for the surface to thaw. If air
temperatures exceed 90° Fahrenheit, flash cool the
surface with water before applying product. Do not
allow products to dry on the surface. Always rinse
thoroughly while still wet.
Sample Panel
Always clean a sample panel prior to the start of full
scale cleaning operations. This should be completed
well in advance of the start date of the final clean
down of the project. Once the sample panel has been
cleaned, it should be allowed to dry completely. Final
approval of the sample panel as well as means and
methods should be given. 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.
Dilutions
NMD 80 is diluted 4 parts water to 1 part NMD 80. An
EC Jet 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. (For a clearer understanding of how to use
an EC-Jet watch our video at www.eacochem.com.)
Coverage Rates
Coverage rates with NMD 80 using an EC Jet 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.
Application Instruction
Low Pressure Application
1. Lightly pre-wet or flash-cool the surface (do not
soak).
2. Apply NMD 80 through an EC Jet 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.
Dilutions
NMD 80 is diluted 4 parts water to 1 part NMD 80. An
EC Jet 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. (For a clearer understanding of how to use
