Degraded, crumbling plaster is a common issue in many homes and buildings across South Africa. What often starts as minor flaking or surface damage can quickly escalate into a bigger structural and aesthetic problem if left untreated.
One of the main causes of this deterioration is a phenomenon known as salt attack. While many property owners attempt to repair damaged plaster with patching or repainting, these solutions are usually temporary and fail to address the underlying issue.
At Aquagard, we offer a practical and effective solution to this problem with Aquagard PlasterCon — a product specifically designed to stabilise degraded plaster, prevent further damage, and extend the life of your walls.
In this article, we explore what causes plaster degradation, why it continues to return, and how PlasterCon provides a reliable, long-term solution.
What Is Salt Attack?
Salt attack is a process where moisture carries soluble salts into plaster and masonry surfaces. These salts are typically present in building materials, groundwater, or the surrounding environment.
As moisture moves through the wall and evaporates at the surface, it leaves behind salt deposits. Over time, these salts accumulate and begin to crystallise within the plaster.
This crystallisation process creates internal pressure, which causes the plaster to:
- Crack and weaken
- Flake or powder
- Lose adhesion to the wall
- Eventually crumble and fall away
This is why salt attack is often associated with visibly deteriorating plaster that continues to worsen over time.
Common Signs of Degraded Plaster
Salt attack and moisture-related damage can be identified through several clear warning signs:
- Powdery or chalky plaster surfaces
- Flaking or peeling paint
- Crumbling or hollow-sounding plaster
- White salt deposits on walls
- Damp patches that persist or return
- Difficulty getting paint to adhere properly
These symptoms are often more noticeable in areas exposed to moisture, such as lower wall sections, exterior walls, and areas affected by rising damp.
Why Traditional Repairs Fail
Many property owners attempt to fix degraded plaster by:
- Repainting the surface
- Applying fillers or skim coats
- Patching only visibly damaged areas
While these methods may temporarily improve appearance, they do not address the root cause of the problem.
The underlying issues, moisture movement and salt contamination, remain active within the wall. As a result, the damage quickly returns, often more severe than before.
A successful solution requires stabilising the plaster, reducing moisture ingress, and preventing further salt-related deterioration.
Aquagard PlasterCon: A Proven Solution
Aquagard PlasterCon is specifically formulated to treat degraded plaster caused by salt attack and moisture exposure.
It works by penetrating deep into the plaster and binding the loose, weakened material, effectively restoring its strength and integrity.
Unlike surface-level treatments, PlasterCon addresses the problem within the substrate, making it a far more effective and long-lasting solution.
How PlasterCon Works
1. Penetrates and Binds Crumbling Plaster
PlasterCon is designed to penetrate deeply into degraded plaster, binding loose particles together and stabilising the surface.
This stops further crumbling and creates a solid base for finishing and painting.
2. Water-Repellent Protection
One of the key features of PlasterCon is its water-repellent properties.
By reducing the amount of moisture entering the plaster, it helps prevent the conditions that lead to salt attack and ongoing deterioration.
This protective layer significantly slows down the cycle of damage and improves long-term performance.
3. Prevents Further Degradation
By addressing both the structural weakness of the plaster and the moisture that contributes to salt attack, PlasterCon provides a dual-action solution.
This helps ensure that once the plaster is treated, it remains stable and durable for much longer.
Additional Benefits of PlasterCon
Cost-Effective Solution
Replacing plaster entirely can be expensive and time-consuming. PlasterCon offers a cost-effective alternative by stabilising existing plaster and extending its lifespan.
This reduces labour, material costs, and project downtime.
Easy Application
PlasterCon is designed for easy application using a low-pressure spray system, making it efficient for both small and large areas.
This simplifies the treatment process and allows for consistent coverage.
Suitable for DIY and Professionals
Whether you are a contractor or a homeowner, PlasterCon is suitable for both DIY applications and professional use.
Clear application methods and minimal specialised equipment make it accessible without compromising effectiveness.
Ideal Primer Before Painting
PlasterCon also acts as an excellent water-repellent primer before painting on new plaster.
By stabilising the surface and reducing moisture absorption, it improves paint adhesion and ensures a longer-lasting finish.
Effective Against Mild Rising Damp
While severe rising damp requires a full treatment system, PlasterCon can be effective in managing mild rising damp conditions by reducing moisture penetration and stabilising affected areas.
This makes it a versatile solution for various moisture-related issues.
Where Can PlasterCon Be Used?
PlasterCon is suitable for a wide range of applications, including:
- Interior walls affected by salt attack
- Exterior walls exposed to moisture
- Renovation and restoration projects
- Preparation of new plaster before painting
- Areas with mild damp-related issues
Its versatility makes it a valuable product for both maintenance and repair work.
