Schonox US is a cement-based self-leveling compound designed for use on cement- and gypsum-based substrates. This compound is designed for fast leveling in interior and exterior areas. It can be installed above 1/8” up to 3”. Schonox is water- and frost-resistant and may be used on both interior and exterior surfaces. It has no moisture vapor emission limitations on properly prepared concrete. This low-shrinkage, pumpable compound is easy to apply. Users can layer thicknesses above 1/8“ up to 1.5“ without aggregates or layer thicknesses up to 3“ with aggregates.
