Abstract: PURPOSE: To smoothen foam in a liquid phase to form a smooth foam layer on an irregular surface by keeping the same foam volume in a liquid phase and in a setting phase, for preventing inflation during setting. CONSTITUTION: A settable composition composed chiefly of an unsaturated polyester and a monomer containing an ethylenic unsaturated coupling is mixed with a gas in order to obtain foam, whereby this polyester foam is applied about 0.1 to 5 cm. In that case, the foam is applied in site on a roof with an irregular surface and is allowed to set to provide a polyester top layer on the top face of the foam.
