  • Floor treating method and machine
    Patent number: 6440225
    Abstract: A method is provided for stripping a polymer film from a floor surface, comprising the steps of: (a) applying a concentrated alkaline stripper solution including an alkaline agent and a solvent, to the polymer film; (b) allowing this concentrated alkaline solution to chemically act on the polymer film during a contact time of at least 5 seconds; (c) scrubbing the polymer film with a scrubbing device while diluting the concentrated alkaline solution with water, so as to obtain a sludge; (d) vacuum cleaning the floor surface by suction of the sludge, whereby this method is carried out using one floor treating machine. This method is an integrated floor stripping procedure which is considerably more effective than known stripping methods of the prior art.
