High grab adhesives are engineered to provide exceptionally high initial tack, allowing components to be fixed securely in place immediately after application, without screws, nails, or temporary fixation.

Instant Grab for Modern Construction

High-performance adhesives enable contractors to work significantly faster by eliminating drilling and temporary supports. They provide immediate fixation, streamline installation processes, and deliver clean, visually flawless surfaces with consistent professional quality. 

Sikaflex®-118 Extreme Grab 

A market leading high grab adhesive designed for demanding construction tasks.

  • Very high initial grab for heavy components 
  • Excellent adhesion on concrete, masonry, wood, metals, and ceramics 
  • Ideal for wall elements, façade components, stone pieces, and interior finishing 

Sikaflex®-116

A versatile, high tack adhesive for everyday construction bonding.

  • Fixing boards, trims, profiles, and decorative components 
  • Bonding insulation elements and interior finishing parts 
  • Fast repairs and refurbishment work

Modular Building

Modular and industrialized construction of walls and floors rely on methods that reduce labor, minimize rework, and ensure consistent factory quality. High grab adhesives are a perfect fit: they combine fast processing with strong, reliable bonding across numerous substrates. And they allow drywall boards to be bonded directly to wooden skeleton structures—without nails or screws. Benefits: 

  • Significant time savings in production 
  • Elimination of rework (no nail head marks to fill or sand) 
  • Cleaner surface quality and reduced material consumption 

High grab adhesives combined with booster-accelerated curing enable simultaneous bonding and fixation of tiles, wall panels, and accessories in bathroom pods and prefabricated wet rooms. The technology performs exceptionally on ceramics, glass, composites, and coated metals and can be used equally well for sealing purposes. Fast handling strength reduces bottlenecks in the production line. 

Sikaflex®‑545 PowerCure®

  • Extremely fast initial fixation, including on vertical surfaces
  • Broad adhesion spectrum for wood, metals, composites, and coated surfaces
  • Accelerated cure when combined with Sika Booster technology
  • Reliable performance in controlled factory production environments

Broader Industrial and Transportation Use

Thanks to their versatile adhesion profile, high grab adhesives support too: 

  • lift and elevator assembly, bus and coach manufacturing, 
  • last mile delivery of vehicle construction, 
  • refrigerated box assembly and repair. 

These applications highlight how high grab technology creates value by bonding diverse substrates while reducing the need for mechanical fastening.
