SCHÖNOX ZM is a cement-based self-leveling compound suitable for use on cement- and gypsum-based substrates. It is designed for fast leveling on interior floors.
SCHÖNOX ZM produces surfaces with high hardness and strength. Users can layer thicknesses above 1/16“ up to 1/2“ without aggregates or layer thicknesses up to 1“ with aggregates.
SCHÖNOX ZM is suitable for filling, smoothing, and leveling of substrates under:
SCHÖNOX ZM can also be used for filling, smoothing, and leveling of unheated, cement-based substrates under SCHÖNOX Moisture Mitigation Systems.
SCHÖNOX ZM is moisture resistant (interior only). There are no moisture vapor emission limitations on properly prepared concrete. This pumpable compound has very low shrinkage.
SCHÖNOX ZM exceeds minimum Ff/Fl requirements of ASTM and ACI when installed in accordance with the guidelines. It has been tested in accordance with ASTM C1708 and conforms with uSD 96/98/BC.
This compound is rated EMICODE® EC 1PLUS R for very low emissions. It is suitable for castor wheel loadings above 1/16“ according to DIN EN 12529.
SCHÖNOX ZM is suitable on:
*All values are approximate, are subject to local climatic fluctuations based upon conditions at 70°F with atmosphere of less than 65% relative humidity following the recommended mixing ratio. Do not install underlayment or topping before the substrate has dried thoroughly
Mix each 25kg / 55lb. bag with 6.5 liters / 6.8 quarts of water.
*If SCHÖNOX ZM is extended with dry, clean aggregate (aggregate is added last) at a layer thickness of 1/2“–1“, type and amount of aggregate used will affect product performance. As qualities of locally available aggregates vary, we recommend performing tests prior to use on a larger scale. Do not overwater! Foam while mixing, or settling of the sand aggregate while placing, indicates overwatering.
