Curing Information
• Moist curing of masonry mortars is required if
conditions are hot, dry, or windy. In such cases, a
gentle mist of water applied to the surface will prevent
premature drying and improve the strength of the
mortar. Protect mortar from freezing during the rst
48 hours. Plastic sheeting and insulation blankets
should be used if temperatures are expected to fall
below 32 degrees F (0 degrees C).
Typically water will satisfactorily clean tools after using
Stone Mortar Mix. If the material has begun to harden,
warm soapy water may be helpful for cleaning hands and
tools.
