Sika Flex NP1 Caulk 10oz  (Special Bronze)

Sika Flex NP1 Caulk sealant requires no mixing, and typically you'll need no priming to bond many materials, concrete and masonry included. Used as an acoustical sealant, MasterSeal NP 1 lowers 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 acoustical seal. This sealant is a one-component, high performance, non-priming, gun-grade, elastomeric polyurethane.
