{"title":"Ceramic Tile Over Concrete Assembly","description":"\u003cp\u003eCeramic tile over concrete needs a continuous waterproofing layer below the thinset to keep moisture out of the slab and prevent failures at grout lines, drains, and transitions. This assembly groups the four products that build that layer: Surface Seal SB Thermoplastic Rubber Coating as the seamless waterproof membrane, HydroStop Fabric (100% polyester) as the reinforcement at penetrations and seams, and FlexSeal Sealant Caulk plus FlexSeal Self-Leveling Sealant for transitions, drains, and detail work.\u003c\/p\u003e\n\u003cp\u003eCommon use cases include shower pans, balcony substrates, plaza decks, and any horizontal concrete surface that will receive ceramic tile, stone, or pavers in an overburden assembly.
