Method for mechanical treatment of a concrete floor

A method for mechanical treatment of a concrete floor, such as troweling and blade finishing, using a hand-operated, a walk-behind or a ride-on actuator, such as a concrete power trowel, floor treating apparatus or the like, said actuator including one or more operating heads comprising a rotor consisting of two or more attachment arms, whereby troweling elements made of substantially plastic-based material, such as a circular trowel pan or elongated trowel blades attached to the rotor attachment arms, are detachably coupled to the actuator rotor, in particular to prevent discoloration of the treated floor surface during treatment, characterized in that in preparing a concrete floor with optimal physical and visual characteristics, a water-soluble silica-based medium is being applied on the said concrete floor before it is being troweled with the plastic-based concrete troweling elements, wherein said silica-based medium is preventing water evaporation from the concrete floor surface and sealing the treated surface, enabling the floor surface to have adequate moisture for cement hydration, wherein the silica-based medium is reacting with the excess lime in the cement, and thereby accelerating the formation of the surface.
