Protective Coatings and Waterproofing Systems
What Protective Coatings Actually Involve on South African Properties
Protective coatings are not a single product or a once off application. When done properly, they are a system that combines surface preparation, correct material selection, and controlled installation to suit the structure, exposure level, and movement of the building.
On local roofs and walls, we are usually dealing with a mix of harsh UV exposure, heavy summer rainfall, temperature swings, and aging substrates. A protective coating must remain flexible, bond correctly to the surface, and resist cracking over time. This is why we work with liquid rubber systems, torch on membranes, and joint specific sealants rather than generic paints or quick fixes.
In practice, this means assessing drainage fall, identifying weak points like joints and parapets, testing adhesion, and selecting the correct thickness and layering for the coating system. The goal is long term protection, not a temporary cosmetic cover.
Why Our Protective Coating Approach Works Long Term
After more than three decades working on roofs, boundary walls, and waterproofing systems, we have learned that most failures happen because of poor preparation or incorrect product use. Our approach focuses on eliminating those risks upfront.
We do not apply coatings over unstable surfaces, trapped moisture, or existing failures. Every project starts with identifying where water travels, where movement occurs, and where previous systems have broken down. By matching the coating system to those realities, we prevent repeat leaks and premature failure.
Our experience across Johannesburg properties means we understand common problem areas like flat roof joints, sun damaged torch on seams, and boundary walls exposed to constant splash back and rising damp. That local knowledge is what allows our coatings to last.
Who Protective Coatings Are Best Suited For
Protective coatings are ideal for a wide range of residential and light commercial properties, including:
Homes with flat or low slope concrete roofs
Townhouse complexes and sectional title properties
Boundary walls exposed to rain and ground moisture
Older buildings with movement related cracking
Property owners looking to extend roof lifespan without full replacement
They are especially effective where traditional repairs have failed repeatedly, or where replacement would be unnecessarily disruptive or expensive.
Common Problems Protective Coatings Solve
Clients usually contact us after experiencing recurring issues such as:
Persistent roof leaks despite previous repairs
Cracking caused by thermal expansion and movement
UV damage breaking down older waterproofing systems
Water ingress through joints, parapets, and wall interfaces
Dampness on boundary walls and internal finishes
Protective coatings address the root causes of these problems by sealing surfaces continuously, accommodating movement, and shielding substrates from ongoing weather exposure.
Real Benefits and Long Term Outcomes
When installed correctly, a professional protective coating system delivers measurable results:
Reduced risk of future leaks and water damage
Extended lifespan of existing roofs and walls
Improved resistance to UV degradation
Lower maintenance costs over time
Improved property value and peace of mind
Many of our clients choose coatings specifically to avoid repeated call outs and patch repairs. The outcome is a stable, sealed surface that performs year after year.
How Our Protective Coating Process Works
Every project follows a structured process designed to minimise risk and maximise durability.
We begin with a detailed inspection to identify failure points, surface condition, and moisture issues. The surface is then cleaned, repaired, and prepared to ensure proper bonding. Joints, seams, and vulnerable areas are reinforced before the main coating is applied at the correct thickness.
Once cured, the system forms a continuous waterproof and UV resistant barrier that moves with the structure rather than cracking against it.
Protective Coatings FAQs
How long do protective coatings last
When installed correctly and maintained, high quality coating systems can last many years. Longevity depends on exposure, surface condition, and correct application.
Can coatings be applied over existing waterproofing
In many cases yes, but only after proper inspection and preparation. Applying over failing systems without repairs will lead to future problems.
Are protective coatings suitable for flat roofs
Yes. Flat and low slope roofs are one of the most common applications, especially where ponding water and UV exposure are present.
Do coatings stop cracks from returning
Flexible coatings help bridge hairline cracks and accommodate movement, reducing the likelihood of cracks reopening.
Is maintenance required
Minimal maintenance is needed, but periodic inspections help ensure long term performance.
