Water-repellent wall treatment — Protect your facade from rain, dirt and damp

Want to protect your exterior walls from rain, frost and dirt? A water-repellent facade treatment is a practical and affordable solution. It prevents damp problems and extends the life of your facade materials.

What is a water-repellent wall treatment?

A water-repellent wall treatment, also called hydrophobic treatment, involves brushing a transparent, water-repellent paste onto an exterior wall. The paste penetrates deep into the masonry to keep rainwater out while allowing the wall to breathe.

Why treat your facade?

A treated wall is:

  1. Water-repellent: prevents penetrating damp and wet interior walls

  2. Frost-resistant: less risk of damage from water freezing inside the wall

  3. Self-cleaning: dirt, algae and moss are less likely to take hold

  4. Insulating: dry walls insulate better than wet walls

  5. Durable: extends the life of bricks and mortar joints

When do your walls need a water-repellent treatment?

This treatment is particularly suitable for:

  1. Facades without a cavity wall or with porous masonry

  2. Walls with a history of damp problems

  3. Facade repairs or renovations

  4. Protection after facade cleaning

Signs that a facade may benefit from treatment include:

  • Dark damp patches on exterior walls after rain
  • Faster dirt build-up or moss growth
  • Loose plaster or peeling paint
