@mlxs204: We rolled TUZHANSHEN on bare bricks, stacked a DIY “bathtub pool”, filled it up and the fish still stayed dry on the outside. Rain on top, people and fish inside, and the coating stayed solid. It’s not a guide on how to build a pool—just a way to show that on roofs and walls, this paint is more than up to the job#bumbungbocor #dindingbocor #bilikairbocor #bumbungkalisair #waterproof
