WHAT IS CURE & SEALCURE & SEAL takes the properties of both a curing compound and membrane forming sealer and combines them to yield the best performance properties of both. Where normal curing resins last only weeks before they wear off, a CURE & SEAL will last one to two years. It forms a hard and shiny, durable surface that resists all waterborne contaminants and protects the concrete through its infancy and early life when applied properly.
