Stormdry is a scientifically tested masonry protection cream that keeps walls dry and warm with unique water repellent properties, making it stand apart from other thinner protective masonry coatings.

Stormdry works by penetrating masonry and lining the pores rather than blocking them. This allows the wall to breathe yet provides that all important barrier to water ingress to stop masonry becoming saturated. Once applied, it penetrates deeply into the masonry before curing to form a colourless, breathable water repellent barrier. Its colourless formula means it does not alter the appearance of stone, brick or concrete to which it can be applied.

The benefits of Stormdry at a glance.

  • Keeps walls dry & warm
  • Aids the prevention of moisture damage to plaster, timbers and masonry
  • Enhances water resistance and energy performance
  • Long lasting performance due to penetrating deeply beyond the depth of small cracks
  • Effective on a range of substrates
  • The only colourless masonry water repellent treatment that carries BBA approval

How do ProTen use Stormdry to provide protection to properties.

Our knowledge of damp allows us to consider the most appropriate solutions to protect properties which we do through our site surveys and Surveyor Team.  We will recommend Stormdry in situations where we view properties as being susceptible to water ingress and penetrating damp (this may be evident as damp patches on internal walls) and to sometimes compliment a damp proofing system.

In addition, our on-site works means we can carry out the correct preparation and application which is vital to its success.  This is particularly important in situations where masonry is in poor condition and in need of repair for example repairing of cracks and re-pointing.

If you are concerned about damp in your property contact us for advice. We can arrange a site survey and provide you with recommendations on how to resolve the problem.

Stormdry can be used in the following scenarios:

To protect against water ingress

Its application will give a property the benefit of continued protection against water ingress which means walls will stay drier and therefore warmer. This will stop water penetrating through and damaging internal plaster and timbers and can reduce the chances of surface condensation and black mould from forming. We apply it in situations where walls are heavily exposed to wind driven rain, where rain water splashes over a damp proof course often combined where bricks are porous and there is no cavity wall.

As part of a flood resilience programme

Masonry treated with Stormdry, will aid post flood recovery. It will help walls dry out more quickly, meaning there is less chance of complications of moisture affecting timbers and plaster occurring in the future.

To help save energy  

Dry walls are better insulators than wet walls and tests carried out by the University of Portsmouth demonstrate that energy savings of up to 29% are possible by keeping walls dry using Stormdry.

To aid insulation

Stormdry can assist with insulating single brick solid walls in older properties, in listed buildings and in those properties considered as ‘Hard to Treat’ (HTT) ie where cavity wall insulation is not possible due to the age of the property or type of construction.
