About StormDry

What is StormDry?

Stormdry is a deeply penetrating water-repellent cream for the protection of masonry. It prevents rain penetration into masonry materials by lining their pores rather than blocking them allowing the masonry to continue to breathe naturally. Unlike waterproof paints or waterproof coatings, Stormdry retains the natural finish of the masonry so is particularly suited for application to brickwork or stonework.


  • Saves upto 29% energy escaping from your walls
  • Provides water & rain repellency
  • Reduces heat loss
  • Good for the environment
  • Reduces energy bills

Typical Applications

Multi purpose

Stormdry is applied to masonry in a single coat by means of brush, roller, or spray. Once applied, it penetrates deeply into the masonry before curing to form a colourless, breathable water repellent barrier.

  • Treatment of penetrating damp
  • Improving the thermal resistance of masonry by keeping it dry (energy saving)
  • Maintaining the thermal properties of cavity wall insulation by ensuring it remains dry
  • Improving the flood resistance of masonry.
