How can I identify penetrating damp?
Penetrating damp occurs when water penetrates the external material of a building such as your brickwork. Once the water is in the substrate, the moisture begins to seep through to the internal walls. Penetrating damp contains salts and other pollutants that are carried into the façade of the building. Sounds serious, right? And yes, it can be.
Penetrating damp can cause a variety of different issues, including the corrosion of wall ties and metal framework, damage to timber, loss of strength and stability and the growth of algae and lichen on walls.
If penetrating damp is left untreated, the strength of the building’s facade can be affected. Damp substrates can start to deteriorate in the freeze thaw cycles causing cracking and defacing of bricks. If your property is suffering with this, it is vital you seek specialist help to stop the damage spreading.
Properties that are suffering from minor symptoms of penetrating damp can still experience changes that will impact the occupants. One prominent change is the building’s thermal conductivity - this will significantly reduce the property’s insulation, as the moisture continues to seep deeper into the interior walls.
If a building has damp plasterwork, increased heat loss, a damp musty smell and frost damage, there is every chance that the building may be suffering from penetrating damp.
This problem could be the result of defective issues outside of the property including cracks in the masonry, damaged water management systems, broken gutters or defective plumbing.
It is not just your property that will suffer: any form of damp on internal surfaces can make respiratory health problems, such as asthma, much worse.
What can I do to cure penetrating damp?
You will need to fix the underlying building fault or issue that is leading to the penetrating damp. There are also a variety of external water repellents that you can use, depending on the severity of the damage. We have listed our top five water repellents suitable for treating penetrating damp quickly and effectively.
Permagard’s Microshield is an effective high-performing water repellent suitable for external use on masonry materials such as brick, concrete and stone. In one single coat, this microporous repellent will protect masonry materials against penetrating damp.
This ready to use liquid is based on silanes and siloxanes, rapidly curing penetrating damp even at near zero degree temperatures. Simply by applying one single coat of our colourless and odourless solution, you will create a microporous layer, protecting the surface against driven rainwater.
Unlike most water repellents, Microshield can be applied to highly alkaline, dry or damp cement-based surfaces. It's not suitable however for wet green-cured cements or concretes.
Microshield is a reliable water repellent, creating an invisible layer that protects against wind-driven rain and surface moisture.
We also sell it in 25 litre containers for those bigger masonry jobs.
Microshield Ultra Masonry Waterproofing
Microshield Ultra is an advanced masonry waterproofing cream specially designed to create long-lasting protection for brickwork and façades. It protects against efflorescence and destruction by water soluble pollutants as well as against frost damage and the attack of micro-organisms.
This water repellent imparts a strong beading effect to mineral surfaces. The beading effect causes water to simply ‘bead’ on the surface and roll off, allowing the material to maintain its natural moisture balance.

Aside from being an excellent water repellent, Microshield Ultra can also save you money by improving the building’s thermal performance. This water repellent reduces heat loss through damp or wet walls, allowing you to save money on energy bills.
Microshield Ultra guarantees long-life protection due to its ability to penetrate deeply into the surface.
Façade Cream Water Repellent
Façade cream is generally used for waterproofing, creating an invisible barrier against water penetration on external masonry materials.
The water repellent forms a barrier against water and will effectively improve the building’s thermal performance over a period of time. Heat lost through damp or wet walls could reduce up to 30%.

Façade cream will also reduce growth of algae and other organisms which normally appear on damp surfaces by reducing the amount of water available for them to grow.
