Usage

Priming coat for concrete and dense mineral substrates like fibre cement, aerated concrete, gypsum and thin rendering such as Sika® MonoTop®-723 N, Monotop FC, etc. Sikagard®-552 W Aquaprimer can also be used as a primer on firmly adhering existing water based coatings or under cement resurfacing mortar to improve the adhesion in case of concrete surface treated with hydrophobic impregnation. Sikagard®-552 W Aquaprimer is part of a system:
  • 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)
 

Advantages

  • Water dispersed - solvent-free
  • Environmentally friendly
  • Water vapour permeable
  • Can be used as an adhesion promoter for coating or cement based resurfacing mortar
