Liquid watmat is a fast-setting, non-shrinking potting mortar. Occurs as a one-component product based on special cement and admixtures, for mixing only with water. Does not contain chloride and metallic aggregate. It is available in two variants: Watt winter liquid watmat (at ambient temperature up to 15 C), S summer liquid watmat (from 15 C). It has good adhesion to the ground. A color similar to that of concrete. Liquid watmat is a self-leveling mortar.
