About this item

  • FINISH - Stone color blends with natural stone, brick, and concrete for a discreet joint line on veneers and masonry walls; ideal for matching tan and sandstone tones. Delivers a professional look with fewer visible touch-ups on facades daily.
  • APPLICATION - Sikaflex NP1 Stone is a polyurethane construction sealant for expansion joints, control joints, and perimeter sealing on masonry, precast concrete, stone veneer, metal, and wood; great for exterior walls, sills, and trim transitions.
  • MOVEMENT - Elastomeric sealant flexes with thermal expansion and minor building movement to maintain a tight seal at masonry transitions; helps reduce cracking along joint edges. Suitable for joints that move with seasonal temperature changes.
  • WEATHER - Exterior-rated polyurethane resists rain, UV, wind-driven water, and freeze-thaw cycling to help keep masonry joints sealed; durable cure supports long service life. Ideal for residential repairs and maintenance in harsh climates.
  • ADHESION - Strong primerless bonding to many common construction materials helps reduce callbacks; ideal for stone veneer edges and masonry joints. Use proper surface prep and backer rod to control depth and create a durable seal that lasts.

How do I know whether a product is suitable for my project?

Review the product description, intended application, dimensions, materials, compatibility information, and installation requirements before ordering. If you are uncertain, contact us with details about your project and the product you are considering.

Are your products suitable for outdoor use?

Some products are designed for exterior applications, while others are intended only for indoor or protected areas. Check the individual product page for information about weather resistance, moisture exposure, temperature limits, and suitable surfaces.

Can I use these products for structural repairs?

Certain fasteners and connectors may be intended for structural applications, but suitability depends on the building design, load requirements, local codes, and installation method. Structural repairs should be evaluated and completed by a qualified professional when appropriate
