The method comprises forming at least one external coating on the surface of the product to be protected, the coating being constituted by a composition mainly containing a mixture of phosphates, of silica, and of alumina belonging to a P2O5 - SiO2 - Al2O3 system, and, after drying, implementing heat treatment at a temperature that is sufficient at least to transform the external coating into an insoluble cement capable of forming a self-sealing inverse glass of silica. The external coating is formed of a liquid suspension that is applied by spray-painting or by means of a brush, the suspension containing said mixture of phosphates, of silica, and of alumina. Prior to forming the external coating, the product may be impregnated to the core within the residual open pores of the composite material, using a liquid solution of phosphates of sodium and of potassium.
