A pasty, water-based hydrophobic substance specially developed to make mineral surfaces and mostly non-porous concrete durably water-repellent. This is made possible thanks to its high viscosity and long contact time, allowing it to achieve a high level of penetration. For use on horizontal, vertical and overhead surfaces.

  • Permeable to water vapour
  • Practically invisible
  • Negligible volatility
  • Solvent-free
  • Good alkali resistance
