Product description
High-quality sealing material intended for concrete, brick facades and external insulation systems (EIFS).
Features
- one-component
- very good resistance to weather conditions
- deformability + 100 / -50% (according to ASTM C 719)
- cures without gas bubble formation
- flexible
- bonding under the influence of moisture
- low ground pressure
- easy application and removal
- low module
- good adhesion to many different substrates
- solvent-free
- very low emissions
Application
The product is intended for flexible and watertight sealing of expansion joints and adjacent gaps in facades. Due to its very low modulus, SikaHyflex-250 Facade can also be used for sealing in external thermal insulation systems (EIFS).
