A liquid composition is applied onto the surface of the part to be treated, the composition containing a ceramic precursor polymer and a refractory solid filler. After cross-linking, the polymer is transformed into ceramic by heat treatment, and subsequently ceramic is deposited by chemical vapor infiltration. Before the chemical vapor infiltration step, the surface of the part is shaved so as to return the composite part to its initial shape so that the chemical vapor infiltration forms a deposit that fills in the residual micropores in the shaved surface of the part.
