Overview

Sikaflex NP 1 requires no mixing and typically requires no priming to bond to many materials, including concrete and masonry. Used as an acoustical sealant, it reduces sound transmission in partition systems to support high STC values by sealing spaces around cut-outs and at perimeters of partitions. The sealant cures to a tough rubber to form a long-lasting seal.
