MasterSeal NP 1 white polyurethane sealant, formerly Sonolastic NP 1, is a one-component, high performance, nonpriming, gun-grade, elastomeric polyurethane sealant. It requires no mixing and typically requires no priming to bond to many materials, including concrete and masonry. NP1 polyurethane sealant is ready to use and requires no mixing which reduces labor cost.
