PROBLEM TO BE SOLVED: To provide a tile grout composition capable of being easily removed from tile with water alone or a weakly acidic aqueous solution in tile grouting and to provide a curing agent composition which enables it. SOLUTION: The curing agent composition comprises the reaction product between (A) at least one polyalkylene polyether polyol modified polyepoxide resin and (B) a polyalkyleneamine composition comprising a mixture of N-3-aminopropylethylenediamine(N3), N,N'-bis(3-aminopropyl)ethylenediamine(N4), and N,N,N'-tris(3-aminopropyl)ethylenediamine(N5).
