Application

  • Crack-bridging intermediate coat beneath Sikagard®- 550 W Elastic top coat.
  • Filling pores, cavities and blowholes.
  • Levelling / re-profiling layer.


Suitable for:

  • Protection against ingress (Principle 1, method 1.3 of EN 1504-9).
  • Moisture control (Principle 2, method 2.3 of EN 1504-9).
  • Increasing the resistivity (Principle 8, method 8.3 of EN 1504-9).

Description

Sikagard®-545 W Elastofill is a one-part, acrylic, water based, crack-bridging, intermediate surface protection coating for concrete.


It fills surface pores, cavities and blowholes or provides a smooth or textured levelling layer for subsequent protection coating topcoats. Sikagard-545W Elastofill is part of the Sikagard crack-bridging, anticarbonation, surface protection coating system for concrete and complies with the requirements of EN 1504-2.


Features and benefits:

  • Water dilutable.
  • Easy to apply compared to cementitious levelling
  • coats.
  • Smooth filling of pores, small cavities and blowholes.
  • Good diffusion resistance against CO2 reducing the rate of carbonation.
  • Good water vapour permeability.
  • Crack-bridging at low temperatures (-20°C).
  • Retains board mark texture/formwork patterns on finished surface.
  • Resistant to freeze/thaw and de-icing salts.
  • CE marked.
