Abstract: The present invention relates to a composition for use in treatment of a floor surface resulting in increased slip resistance of the surface. The present invention further relates to a method for treatment of a floor surface resulting in increased slip resistance of the surface. The present invention also relates to the use of a composition for the treatment of a floor surface. Specifically, the present invention relates to methods for treatment of a stone floor surface resulting in increased slip resistance of the surface, comprising step (a) comprising contacting the surface during a sufficient time period with a composition, which composition is an aqueous composition comprising at least a suitable inorganic fluoride-containing compound and such compositions and the use thereof.
