What was formerly known as Sonolastic NP1, the one-component, high-performance, non-priming, gun-grade elastomeric polyurethane sealant has been re-branded and is now MasterSeal NP 1. This product requires no mixing and no priming before bonding to most materials including concrete and masonry. Another interesting feature of Master Builders Solutions new product is its ability to reduce sound transmission when used as an acoustic sealant. MasterSeal NP 1 also supports high STC values by sealing the spaces or gaps around cut-outs and at perimeters of partitions.
