Abstract: A method in dry shake coating of a concrete floor is provided. On top of the concrete floor two or more superimposed dry shake material layers are applied. The surface of an underlying dry shake layer is troweled prior to application of a next dry shake layer, whereafter the lastly processed dry shake layer of a concrete floor is troweled. 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.

Abstract: A method for a 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 machine, a floor treatment machine or the like, is described. The actuator has one or more operating heads comprising a rotor consisting of two or more attachment arms. The floor surface is treated by means of concrete troweling elements, such as circular trowel pans or elongated trowel blades attached to the rotor attachment arms, made substantially of plastic material, that are detachably coupled to the rotor of the actuator, in particular to prevent discoloration of the treated floor surface during treatment. Before the concrete floor is troweled with plastic-based concrete troweling elements, a water-soluble silica-based medium is applied on it.

Abstract: A tool for the mechanical treatment of a concrete floor, such as for power trowel floating and finishing with blades, for conducting the treatment with a hand-operated, walk-behind or ride-on actuator, such as e.g. with a concrete power trowel, a floor treating apparatus, or the like. The actuator includes one or more operating heads, which include several, such as four, attachment arms perpendicular to each other, for treating a concrete floor with tools coupled in a removable manner into the engagement with each attachment arm. A tool is intended for use in engagement with a trowel floating blade coupled to an attachment arm of the actuator's operating head, whereby the tool with a substantially flat and elongated body includes first and second elements for its coupling and locking on a quick coupling principle for im-movable engagement with the trowel floating blade.

Abstract: A method and an arrangement used in floor surface treatment. Especially the finishing of a concrete, epoxy, dry shake floor or the like is conducted by using a trowel tool fabricated from a substantially plastic-based material and removably connectable to the operating head of a concrete trowel machine, the purpose being to prevent discoloration of a presently treated floor surface while finishing the same. A trowel tool is fastened to the operating head of a concrete trowel machine used in floor surface finishing for final troweling by means of the Velcro attachment principle by making use of attachment surfaces, which are included on the one hand in the operating head of a concrete trowel machine and on the other hand in the trowel tool and which are removably fastenable to each other.

Abstract: 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.
