The present invention is directed to a method for producing a condensed phase of a silk fusion protein, the method comprising the steps of preparing a solution of a silk fusion protein in an aqueous medium and concentrating said silk fusion protein in said aqueous medium, wherein said fusion protein is isolated from a recombinant production host and comprises a silk-like protein sequence and two separate non-silk terminal module sequences, such as cellulose binding modules, SpyCatcher domains, tenth type III module of Fibronectin, gamma- crystallin D, flanking said silk-like protein sequence; wherein the method is performed so that said silk fusion protein is not precipitated and subsequently dissolved to said aqueous medium.The present invention is also directed to using such fusion proteins as adhesives.
