Waterproofing a deck completely is a major process. In this video, Matt Risinger, master builder describes the process of putting the deck on the second floor of the modern dock with a boat slip on the first floor. Risinger describes researching and coming up with the solution shown. It is a cold-ply fluid roofing and waterproofing system by Kemper Systems America. A Kemper rep describes the system. It differs from thermoplastic, PVC-type and membrane systems commonly used. It is the use of Kemper membranes that can be installed on any new roof with direct application to plywood, concrete and metal. It consists of up to 80% renewable resources including recycled fibers, and is odor-free and solvent-free, eliminating many environmental considerations. The seamless membrane fully adheres to the surface. It is resistant to ponding water and ice. First a primer is put down and the substrate is repaired where necessary. A durable urethane primer is put down and this makes the substrate completely waterproof. The topcoat is a membrane. Liquid is put onto the substrate and the fabric is rolled onto that. Liquid again is used on top of the fabric, which completes the seal. Watch the video to see how the fabric is put down and overlapped. Typically, within four hours it is tight enough so that water cannot hurt it. Fully cured is from 12-16 hours. There are no issues with flashings. It feels like it is one continuous membrane, eliminating termination bars and gaskets and lowering cost.
