Sika Level-125CA 22.7kg Polymer-Modified Hi-Flow Self-Leveling Underlayment is a one-component, polymer and Viscocrete modified cementitious underlayment for interior concrete, cementitious, wood and tiled substrates. Its hi-flow, self-levelling properties allow it to be applied, either manually or by pump, to produce a fast-setting, flat and economical substrate prior to the application of a final floor finish. Typical application thickness is 1 to 38 mm (1/25 to 1 1/2 in).
