A composite waterproof construction method using a waterproof elastic coating material and epoxy is disclosed. According to a preferred embodiment of the present invention, a waterproof elastic coating material is applied to a base surface, and epoxy is constructed on the applied waterproof elastic coating material, wherein the waterproof elastic coating material contains 70 to 85 wt% of an isocyanate prepolymer, 10 to 25 wt% of a latent curing agent, and 0.5 to 2 wt% of an adhesion promoter. According to the present invention, a waterproof layer can be directly applied to a structure, etc., without applying a primer so that the cost and time for waterproof layer application can be greatly reduced. A waterproof layer that has excellent physical properties such as adhesiveness, elasticity, etc., excellent waterproof performance, and specifically, excellent waterproof performance even in a humid environment can be constructed. Composite waterproof construction is possible without affecting different waterproof layers. In addition, a floor can be finished in various forms that are both wear-resistant and aesthetically pleasing. 방수용 탄성 코팅재와 에폭시를 이용한 복합 방수 시공 방법이 개시된다. 본 발명의 바람직한 일 실시예에 따르면, 바탕면에 방수용 탄성 코팅재를 도포하고, 도포된 방수용 탄성 코팅재에 에폭시를 시공하며, 방수용 탄성 코팅재는, 이소시아네이트 프리폴리머 70 내지 85 중량%, 잠재성 경화제 10 내지 25 중량% 및 접착 증진제 0.5 내지 2 중량%를 포함하는 방수용 탄성 코팅재이다. 본 발명에 따르면, 프라이머를 시공하지 않고도 구조물 등에 바로 방수층을 시공할 수 있어 방수층 시공에 비용과 시간을 크게 절감할 수 있고, 부착력과 탄성 등과 같은 물성이 우수하고 방수 성능도 우수하며, 특히 습윤한 환경에서도 우수한 방수 성능을 가지는 방수층을 시공할 수 있고, 서로 다른 방수층에 서로 영향을 주지 않으면서도 복합 방수 시공이 가능하고, 또한 내마모성을 가지면서 미관을 고려한 다양한 형태로 바닥을 마감할 수 있는 장점이 있다.
