Applikation

Sikagard®-550 W Elastic is used for protection and enhancement of concrete structures (normal and lightweight concrete), especially exposed outdoor concrete surfaces with a risk of cracking.


Sikagard®-550 W Elastic is used with concrete repair works as an elastic protective coating on Sika® smoothing mortar (refer to relevant product / system data sheet), fibre cement and overcoating of existing soundly adhering coatings.

  • Suitable for protection against ingress (Principle 1, method 1.3 of EN 1504-9).
  • Suitable for moisture control (Principle 2, method 2.3 of EN 1504-9).
  • Suitable for increasing the resistivity (Principle 8, method 8.3 of EN 1504-9).


Beskrivning

Sikagard®-550 W Elastic is a one component, plastoelastic coating based on UV-curing acrylic dispersion with excellent crack-bridging properties even at temperatures below 0 °C. Sikagard®-550 W Elastic complies with the requirements of EN 1504-2 as protective coating.


Features and benefits:

  • Crack-bridging even at low temperatures (-20°C).
  • High diffusion resistance against CO2 reducing the rate of carbonation.
  • Water vapour permeable.
  • Very good resistance against weathering and ageing.
  • Environmentally friendly (solvent free).
  • Reduced tendency to dirt pick up and contamination.
  • The system is resistant to aggressive atmospheric influences.
  • CE marked.
