Sikaflex® sealants and adhesives are engineered to provide long-term, cost-effective solutions to meet your construction needs. Proven for over four decades, Sikaflex® polyurethanes are ideal for a wide range of construction needs.



  • Adhesion: Sikaflex® sealants will bond to a wide variety of surfaces, particularly porous substrates such as concrete and masonry, without the use of a primer. Sikaflex® polyurethanes are recognized for their superior wetting action which results in an enhanced bond to many substrates under job site conditions.

  • Dirt Resistance: Because of their exclusive chemical design, Sikaflex® sealants exhibit far less dust and dirt pick-up during cure and over their service life.

  • Substrate Staining: Sikaflex® sealants possess an extremely stable consistency and seldom stain common and even stain-susceptible substrates.

  • Paintability:  Sikaflex® sealants may be over-coated with most coatings and paints.

  • Immersion: A number of Sikaflex® sealants may be totally immersed without being affected.
