Masonry matters - how to protect walls in winter 

When winter arrives in the UK, our unpredictable weather can really take a toll on commercial properties, especially on their exterior walls. If you're a property manager or work in maintenance you'll know that freezing temperatures, heavy rain and frost can lead to severe damage. And worst of all, this almost always results in costly repairs. Understanding how to protect walls in winter is essential to ensure the longevity and structural integrity of buildings. In this blog we're talking about what happens - and what you can do to protect the buildings you look after... with a little help from Kingfisher!

Why winter is tough on masonry

Winter’s freeze-thaw cycle is one of the biggest culprits for masonry damage. Moisture seeps into masonry surfaces, and then when the temperatures drop, it freezes, expanding and causing cracks to appear. Over time, the process really weakens the structure - and this allows penetrating damp to take hold. Not only does this affect the building’s appearance - it also compromises its energy efficiency and long-term durability.

The right products to protect masonry

Fortunately, we've got the high-performance products you need to protect your properties during the harsh winter months. Here’s what we recommend:

1. Weatherflex Masonry Paint

Available in a beautiful range of contemporary colours inspired by the Lakes & Fells we call home, Weatherflex is more than just a paint. It’s a high-quality masonry coating designed to endure the worst weather conditions - and we've definitely got experience with these! The beauty of Weatherflex is its flexibility. This allows it to absorb seasonal temperature changes without cracking, peeling, or flaking. The breathable formulation we've perfected ensures moisture can escape while keeping water out. This means it is an excellent choice for long-term performance. This durability, combined with its heritage in protecting barn conversions in the harshest remote locations in Cumbria, has earned Weatherflex a loyal following nationwide.

2. Extreme Climate Masonry Water Seal

For properties that are exposed to persistent rain, coastal winds, or upland weather, Extreme Climate Masonry Water Seal is the ultimate defence. It's an invisible, breathable sealant and it prevents penetrating damp by working deep into brick, stone, and mortar. It’s especially effective at combating the freeze-thaw cycle and can even reduce heat loss through evaporation. With a 10-year lifespan, it’s a reliable choice for maintaining the structural integrity of the walls you're looking after.

Take action this winter

If you’re responsible for maintaining commercial properties, it’s really crucial that you use the right products to save you time and money in the long run. By using high-performance products like Weatherflex and Extreme Climate Masonry Water Seal, you can protect walls from the damaging effects of winter weather. Don’t let penetrating damp, frost damage, or unsightly cracks undermine your maintenance efforts.
