Abstract

PURPOSE: To apply a high density polyurethane foam layer having high bonding strength, to the cut or ground surface of a polyurethane foam, by spray foaming process.
CONSTITUTION: A polyurethane foam layer (b) is applied to the wall (a) of a construction. The rugged surface (d) of the polyurethane foam (b) is shaped to a flat surface (c) by cutting or grinding. A stock liquid of urethane for the preparation of polyurethane foam (e.g. containing polyhydroxy compound, polyisocyanate, a foaming agent, flame retardant, catalyst, etc.), wherein the foaming agent is absent, is sprayed to the flat surface (c) in a thickness of 1W5 mm to form a high density polyurethane foam layer (e). A surface polyurethane layer (f) is formed on the high density foam layer (e) by spraying a urethane stock liquid containing a foaming agent to the high density layer (e).
