Liqui-Deck is a solvent-free, two-compound polyurethane compound for preparing and leveling rough concrete surfaces prior to the installation of CCW MiraDRI 860/861 Sheet Membrane Waterproofing. The compound cures overnight to a fully adhered elastomeric sheet, providing a temporary waterproofing layer prior to the installation of the waterproofing membrane. The low-viscosity compound fills voids and cures to form a well adhered elastomeric membrane.
