Sika Sikaflex NP 1 Polyurethane Sealant, White – 10.1 oz Cartridge
Sikaflex NP 1 Polyurethane Sealant, White 10.1 oz
Sikaflex NP 1 is a one-component, gun-grade polyurethane sealant that bonds without priming to many materials, including concrete and masonry. It cures to a tough, elastomeric seal and also serves as an acoustical sealant to help reduce sound transmission in partition systems.
Key Features:
- One-Component Convenience: No mixing required; typically bonds without primer to common building materials
- Durable Elastomeric Seal: Cures to a tough, flexible rubber for long-lasting joint performance
- Acoustical Performance: Helps reduce sound transmission by sealing gaps around cut-outs and perimeters
- Versatile Applications: Suitable for concrete, masonry, and general waterproofing tasks
- White 10.1 oz Cartridge: Standard gun-grade format for easy application on site

The white, gun-grade polyurethane forms a supple, architectural joint that looks tailored and remains resilient. Use it to frame door casings and partition perimeters for a hushed, gallery-like finish. It’s the discreet detail that signals refined, luxurious craftsmanship.
Choose Sikaflex NP 1 to achieve a durable, acoustically smart seal that installs easily and looks impeccably clean.
