Many homeowners want to protect their brickwork from the weather.
After years of rain, frost and changing temperatures, it's natural to look for a product that will stop water soaking into external walls.
One question we hear regularly across Bolton is:
👉 "Should I apply a waterproof sealer to my brickwork?"
It's a sensible question, but not all water-repellent products work in the same way.
Traditional masonry sealers often create a surface coating that can restrict the wall's natural ability to breathe.
Modern breathable masonry protection systems take a different approach, helping to repel rainwater while still allowing water vapour to escape from the building fabric.
Understanding the difference is essential when protecting your home for the long term.
🧱 Brickwork Needs To Manage Moisture
No external wall remains completely dry throughout the year.
Brickwork is naturally exposed to:
- Rain
- Frost
- Wind
- Temperature changes
- Airborne moisture
Traditional masonry has always been designed to absorb a small amount of water before drying naturally as conditions improve.
Problems usually arise when walls remain saturated for prolonged periods.
💧 What Do Traditional Water Sealers Do?
Many older masonry sealers work by creating a coating on the surface of the wall.
Initially this may reduce rainwater absorption.
However, some products can also reduce the wall's ability to release moisture already trapped inside the masonry.
If moisture cannot evaporate effectively, it may contribute to:
- Decorative damage
- Frost damage
- Trapped moisture
- Reduced wall performance
Not every traditional sealer behaves this way, but it's important to understand how the product interacts with the building before it's applied.
🌬️ Why Breathability Matters
Older and modern buildings both rely on moisture being able to move naturally through the building fabric.
A breathable masonry protection system allows water vapour to escape while significantly reducing the amount of rainwater entering the wall.
This helps maintain the natural moisture balance within the masonry.
Instead of trapping water inside, the wall is able to continue drying.
🌧️ Keeping Rain Out While Letting Vapour Escape
The ideal external wall protection system performs two important functions:
✔ It repels rainwater from the outside.
✔ It allows water vapour to escape from the inside.
This combination helps reduce long-term wall saturation without preventing the masonry from breathing naturally.
🏠 Why Saturated Walls Cause Problems
When brickwork repeatedly absorbs excessive moisture, several issues can develop over time, including:
- Penetrating damp
- Green algae growth
- Moss formation
- Freeze-thaw damage
- Decorative staining
- Reduced thermal performance
Keeping masonry drier helps reduce the likelihood of these moisture-related problems developing.
❄️ Freeze-Thaw Damage Can Shorten The Life Of Brickwork
One of the biggest causes of masonry deterioration is the freeze-thaw cycle.
Here's what happens:
- Rainwater enters the brickwork.
- Temperatures fall below freezing.
- The trapped water expands.
- Pressure develops within the masonry.
Repeated over many winters, this can gradually weaken bricks and mortar.
Reducing rainwater absorption helps reduce the amount of moisture available to freeze.
🛡️ How Modern Breathable Masonry Protection Works
Modern systems, such as those manufactured by ProPERLA, don't simply create a coating on the surface.
Instead, they penetrate into the masonry and form an invisible hydrophobic barrier.
This means:
✔ Rainwater beads and runs off the wall.
✔ Water vapour can continue escaping naturally.
✔ The appearance of the brickwork remains largely unchanged.
✔ The wall continues to breathe.
This approach helps protect the building while respecting the way masonry naturally manages moisture.
💧 Why We Recommend ProPERLA Masonry Protection
At Weather Wise Solutions Limited, we install breathable masonry protection systems from ProPERLA UK.
ProPERLA is designed to reduce rainwater absorption while maintaining vapour permeability, helping external walls stay drier without trapping moisture.
Potential benefits include:
✔ Reduced water absorption
✔ Faster drying after rainfall
✔ Reduced algae and moss growth
✔ Improved resistance to freeze-thaw weathering
✔ Long-term protection for brick and stonework
This makes it particularly suitable for homeowners looking to protect their property against future moisture-related deterioration.
⚠️ Protection Should Never Replace Repairs
Breathable masonry protection works best when the wall is already in good condition.
Before applying any protective treatment, we always inspect for:
- Cracked render
- Defective pointing
- Damaged brickwork
- Failed sealants
- Leaking gutters
Addressing these issues first ensures the protection system performs as intended.
🔍 How We Assess External Walls
At Weather Wise Solutions Limited, we assess:
- Brickwork condition
- Mortar joints
- Moisture exposure
- Rainwater absorption
- Existing defects
- Long-term wall performance
Because the important question isn't:
👉 "Can we waterproof the wall?"
It's:
👉 "How can we best protect the wall while allowing it to continue breathing?"
🛠️ How We Help Protect Masonry
Depending on the property's condition, recommendations may include:
- Repointing
- Render repairs
- Crack repairs
- Rainwater goods maintenance
- Breathable masonry protection
- External wall maintenance
Our goal is always to reduce future moisture exposure while preserving the long-term health of the building.
👨🔧 Signs Your Brickwork May Benefit From Protection
Consider having your external walls professionally assessed if you notice:
✔ Brickwork staying wet long after rainfall
✔ Green algae or moss growth
✔ Weathered mortar joints
✔ Fine cracks developing
✔ Damp patches internally
✔ External walls that appear consistently darker than surrounding properties
These signs may indicate that the masonry is absorbing more water than it should.
