The invention relates to a pulverulent composition preparable by contacting a powder with 0.01 to 50 wt %, based on the overall mass of the composition, of a liquid component comprising at least one copolymer obtainable by polymerizing a mixture of monomers comprising (I) at least one ethylenically unsaturated monomer which comprises at least one radical from the series carboxylic acid, carboxylic salt, carboxylic ester, carboxylic amide, carboxylic anhydride, and carboxylic imide and (II) at least one ethylenically unsaturated monomer having a polyalkylene oxide radical, the liquid component comprising at least 1 wt % of the at least one copolymer and at least 30 wt % of an organic solvent, and the powder which is contacted with the liquid component comprising no inorganic binder. Further disclosed is a binder composition which comprises a pulverulent composition of the invention and an inorganic binder.
