A method in dry shake coating of a concrete floor, whereby an applied floor concrete mass is subjected to early after-care, in which connection, if necessary, after floating, on top of the floor concrete mass is applied a dry shake material for two or more superimposed dry shake layers, in which connection the surface of a currently underlying dry shake layer is troweled prior to the application of a next dry shake layer to be processed thereupon, whereafter the lastly processed dry shake layer of a concrete floor is troweled and the concrete floor is subjected to actual aftercare. The application of an underlying dry shake layer is followed by spreading over its surface a water soluble silica-based medium prior to and/or during the course of troweling this particular dry shake layer and prior to the application of an overlying dry shake layer to be spread thereupon.
