<p>[PROBLEMS] To provide a urethane waterproof material that in various functions, exhibits high performance. [MEANS FOR SOLVING PROBLEMS] There is provided urethane waterproof material (3) comprising a coating obtained by mixing a main agent of high-speed hardening urethane resin with a hardening agent therefor according to spraying technique, characterized in that a vast plurality of air pores are present in the coating. By virtue of the presence of a vast plurality of air pores in the coating, high performance can be exhibited in the thickness freedom, elasticity, elongation ratio, steam permeability, heat insulation/cold protection, crack follow, quick hardening property, etc.</p> |
