How to protect against rainwater infiltration?

Walls and porous roofs can be protected against rainwater infiltration in a simple way: by applying hydrophobic treatment. This technique makes porous surfaces water-repellent, preventing rainwater from penetrating the wall while still allowing vapor transport from the inside out.

How do you proceed?

  • Clean the surface with Green Cleaner and let it dry.
  • Shield the surfaces that should not be treated and avoid application in direct sunlight.
  • For large surfaces, use Parafuge Facade F.
    • Apply in one coat or treatment using a sprayer.
    • Start at the top with a 40 cm strip and make a back-and-forth motion.
      Spray the liquid like a curtain over the surface to fully saturate it.
  • For smaller surfaces, use Parafuge Facade G. Apply with a low-pressure gun, roller, or brush.
