General Preparation
Protect adjacent and surrounding surfaces not intended to be cleaned.

Surface and Air Temperatures
Avoid damage to masonry surfaces. Do not clean when temperatures are below freezing or are expected to be below freezing the night before cleaning. If freezing conditions exist prior to application, allow adequate time for masonry surfaces to thaw. Best cleaning results are obtained when air and surface temperatures are 40º Fahrenheit or above.

Always test prior to beginning full-scale cleaning operations. Testing should confirm cleaning effectiveness on each type of surface and stain designated to be cleaned. Test also to determine the desired surface contact time and any potential for adverse reactions with adjacent materials. Allow test panels to dry thoroughly before evaluating final appearance and results.

Use undiluted
Use NMD 80 undiluted up to a 4:1 dilution as an additional application for trace removal.


General Application
To quickly soften heavy deposits, apply the product undiluted via sprayer directly on the areas of calcite. A heavy white foam will result. If the calcite deposit is very thick, allow this foam to collapse completely and repeat this application. Do a scratch test on the surface to see if the calcite is softened. If not, repeat above steps. Once the calcite has softened, without rinsing apply NMD 80. Heavy white foam will form. Calcite is totally gone when white foaming ceases. If you see green foam when using undiluted NMD80, there is no calcite. Rinse immediately. You can rinse with a trigger sprayer, garden hose or pressure rinse off. Finish with applications of NMD 80 diluted at 4:1, then rinse off thoroughly.

Note: Do not allow Calcite Presoak to run down the surface, bleaching may occur. Apply enough product on the calcite deposits without over soaking to avoid runs. If runs occur, rinse the excess immediately.
