MasterSeal 10.1 oz. Redwood Tan Elastomeric Polyurethane Sealant (10.1 oz., Redwood Tan)

MasterSeal NP 1 (formerly known as Sonolastic NP 1) is a one-component, high-performance, non-priming, gun-grade, elastomeric polyurethane sealant. It requires no mixing and typically requires no priming to bond to many materials, including concrete and masonry. Used as an acoustic sealant, MasterSeal NP 1 reduces sound transmission in partition systems to support high STC values by sealing spaces around cut-outs and at perimeters of partitions. One-component formula requires no mixing, helping to reduce labor costsJoint movement capability ±35% provides excellent flexibility for keeping moving joints weathertightEasy to gun and tool, speeding up application and making neater jointsNo primer required for most construction materials lowering installation costsWeather resistant for long-lasting weather tight sealsCompatible with non-rigid coatings and can be paintedSuperior holding power for long-lasting roof tile installation
