Happilac Hi-Aqua Seal WR-66 is a water-based masonry water repellent that penetrates deep inside the pores of substrates and forms a resin coating by reacting with atmospheric carbon dioxide. The methyl silicon resin thus formed impregnates the substrate providing water repellency without altering the appearance and retaining the breathability of the substrate.

  • Good water repellency to masonry surfaces
  • Easy to apply and ready to use
  • Deep penetration and improved aesthetics
  • Long term effectiveness over 5-10 days
