Product: NMD 80
The general problems associated with limestone in new construction
clean-up have all been solved just by the use of NMD
80 . Mortar smears, clay stains, rust, tannic acid stains
and biological stains are all generally removed easily by
the “80”.( SafeRestore
quickly removes any subsequent discoloration that occurs because
of bad water or minerals in the limestone.)
Application: We recommend a complete but lightweight
prewetting of the stone followed by a spray on application
of NMD 80.
Dilution: We have exposed historic register limestone
buildings to up to four repeat straight applications of NMD
80 with no detrimental effect, so dilution is not critical.
Recommended dilution is between 4:1 to 7:1 depending how much
mortar smear is on the stone.
Removal: Care should be taken to apply the product
on the surface evenly and rinse evenly. Nozzle degree should
not be less than 25 degrees and care should be taken to not
get close enough to etch the surface with the pressure.
Safe
On Glass And Anodized Aluminum
NMD80 is frequently used
to clean new construction when the windows have already been
installed. We have experienced no difficulty with the product
affecting the glass or the anodized aluminum when used at
normal brushless cleaning strength.
