PURPOSE: To carry out waterproof execution in high efficiency by coating a rapid curing type urethane resin paint to a place to be executed according to a mixing and emitting system to shorten the period for execution and work to a large extent.
CONSTITUTION: A composition containing an isocyanate prepolymer obtained by reacting tolylene diisocyanate and polyether polyols and a composition comprising containing diamino diphenylmethane are used as a urethane resin type coating material. Said both compositions are emitted and coated by using a mixing and emitting apparatus capable of carrying out mixing and emitting at the same time substantially to attain rapid curing and, thereby, highly efficient waterproof execution can be carried out in a short period of time.
