Sikagard®-545 W Elastofill is an elastic acrylic copolymer dispersion intermediate Sikagard®-545 W Elastofill is part of a crack-bridging system comprising of:

  • Sikagard®-551 S Elastic Primer (solvent containing) or
  • Sikagard®-552 W Aquaprimer (water-based) as a primer


Sikagard®-545 W Elastofill is designed as a crackbridging intermediate coat in combination with Sikagard ®-550 W Elastic.
Sikagard®-545 W Elastofill as a filler coat closes pores, cavities and blowholes.
Sikagard®-550 W Elastic as a coloured top coat protects and embellishes.
Sikagard® crack bridging system is used for protection and enhancement of concrete structures (normal and lightweight concrete), especially outdoor exposed concrete surfaces with a high risk of cracking.

  • 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)


  • Water thinnable, ecologically harmless
  • Easy to apply
  • Easy filling properties for pores, small cavities and blowholes
  • Outstanding carbonation inhibitor
  • Good water vapour permeability
  • Crack-bridging even at low temperatures (-20°C)
  • Can retain board mark texture/formwork patterns if required
  • Resistant to freeze/thaw and de-icing salts
