Description
Triple Guard Asbestos Encapsulation System
The Triple Guard System is a professional multi-layer asbestos encapsulation system designed to stabilise, seal, and protect ageing asbestos-cement roofing and exterior surfaces.
Developed for New Zealand conditions, the system combines fibre-binding technology, flexible waterproof membranes, and durable protective topcoats to provide long-term weather resistance and surface protection.
What Is Asbestos Encapsulation?
Asbestos encapsulation is the process of sealing asbestos-containing surfaces with specialised coating systems designed to help minimise fibre release while improving weather protection and appearance. In many situations, encapsulation can provide a cost-effective alternative to asbestos removal.
The Triple Guard System
Step 1 — Fibre-Binding Encapsulation Layer
The first stage penetrates porous asbestos-cement surfaces to help stabilise and bind loose surface fibres while reinforcing the existing substrate.
This important foundation layer helps prepare the surface for subsequent coatings and assists in reducing ongoing surface deterioration.
✔ Penetrates porous asbestos surfaces
✔ Helps bind and stabilise fibres
✔ Reinforces weathered substrates
✔ Improves adhesion for following coats
Step 2 — Sealing & Water-Resistant Membrane
A high-build flexible membrane is then applied to form a continuous protective barrier across the roof surface.
This layer is designed to help protect against moisture ingress, weather exposure, and ongoing degradation caused by New Zealand’s harsh climate conditions.
✔ Flexible waterproof barrier
✔ Helps prevent moisture penetration
✔ Designed for long-term weather protection
✔ Suitable for ageing asbestos roofing systems
Step 3 — Hydrophobic Protective Topcoat
The final protective topcoat provides a UV-stable, dirt-resistant finish designed to improve durability, appearance, and long-term performance.
This hydrophobic coating helps water bead from the surface while improving overall roof presentation and weather resistance.
✔ UV-resistant protective finish
✔ Dirt-repelling hydrophobic technology
✔ Improves appearance and longevity
✔ Designed for New Zealand conditions
