PURPOSE:To improve heat efficiency and temp. distribution, by a method wherein a releasable resin layer is formed on the uncured film provided to the surface of a base material and subsequently heated by steam or hot water to cure the uncured film before the releasable resin layer is released. CONSTITUTION:An uncured heat-curing film is formed on the surface of a base material and, after drying, a layer composed of a releasable resin is formed on said film. Subsequently, the uncured film is heated by steam or hot water to be cured and, thereafter, the releasable resin layer is released. The aforementioned heat-curing film is formed by applying a phenol resin or epoxy/phenol resin. As the releasable resin, there is a vinyl chloride/vinyl acetate copolymer. By this method, a water penetrating layer can be perfectly prevented from being formed on the surface layer of the heat-curing film by steam or hot water.
