1. A method for suppressing the corrosion of a pipe under insulation, comprising a step of applying a paste comprising aerogel particles, a liquid medium, a binder resin, and a fibrous substance to a surface of the pipe to form a corrosion-resistant coating film thereon,
wherein the binder resin comprises a first binder resin and a second binder resin having a lower solubility to the liquid medium than the first binder resin, and the first binder resin is a cellulose-based resin or an acrylic acid-based resin, and
wherein the content of the fibrous substance is 5 parts by mass or more and 25 parts by mass or less, with respect to 100 parts by mass of the aerogel particles.
