Sikalastic®-6100 FX

(former MSeal 6100FX)
One component elastic and flexible lightweight membrane for waterproofing and concrete protection
  • One-component product: only needs water to be added.
  • High elastic properties: high crack bridging abilities static and dynamic, maintains elasticity in immersion and down to -10 °C. High durability and protection without cracking.
 
  • Low density/Lightweight formulation: Low consumption providing high yield and time saving in application.
  • Rapid curing: Allows early service ability. Tanks and reservoirs can be filled after only 3 days of curing.
  • Waterproof at 2 mm thickness: Resists up to 5 bars of water pressure.
  • Excellent adhesion
  • Breathable: Water vapour permeable
  • High resistance to carbon dioxide diffusion: Protects concrete from rebar corrosion. A 2 mm coating provides anti-carbonation cover equivalent up to 18 cm of concrete.
  • Sulphate resistant
  • No ammonia smell: Can be applied in closed spaces.
  • Reduced efflorescence appearance risk
  • UV resistant: can be used as final coating in exterior applications without compromising its mechanical properties.
  • Suitable for contact with drinking water: Complies with Directive (EU) 2020/2184 and WRAS approval certificate.
  • High thickness range: possibility to apply 5 mm in one coat on rough substrates (spray).
  • Barrier to radon gas (radon gas diffusion length 0.23 mm).
  • Classification CM 01-P according to EN 14891 (for use as a waterproofing under cementitious adhesive).
