Mix 1 liter of “Supercrete ” liquid with 2 kg of fresh 43 or 53 grade OPC (do not use lumpy or air set OPC or PPC) thoroughly to make smooth brushable consistency. Such mixed material (say 3 kg.) will provide the coverage between 1.5 m2 and 2m2 depending upon surface texture/porosity on a prepared surface. The thickness varies from 0.9 to 1.1 mm.
