Prepare and stabilise aged asbestos cement sheeting with Crommelin Fibroseal Primer 15L, a specialised waterborne penetrating treatment that soaks into degraded surfaces to bind loose fibres and reinforce the material. Designed as the first step in a proven encapsulation system, this primer strengthens weathered asbestos surfaces so they can be safely and effectively overcoated with a compatible topcoat.

Because it penetrates deep into the substrate, this primer helps lock in unstable fibres and provides a consistent base for the next coating. In turn, it can extend the life of existing asbestos cement products without the need for costly removal or replacement.

Key Features:

• Water‑based penetrating primer that binds weathered asbestos cement fibres for improved surface stability.

• Forms part of the trusted Crommelin Fibroseal System used in Australia for decades to rejuvenate aged asbestos roofs and walls.

• Easy to apply with a brush, roller or low‑pressure spray, helping you complete projects faster.

• Prepares the surface for Crommelin Fibroseal Topcoat for enhanced protection and appearance.

• Low odour and water cleanup simplifies post‑application maintenance.

Ideal For:

• Weathered asbestos cement roofing and wall sheeting where fibres have become loose or friable.

• Projects requiring an encapsulation approach rather than full material replacement.

Application & Performance:
First, ensure the surface is clean and free of loose material. Then apply Fibroseal Primer so it can penetrate through lichen and degraded fibres down to the solid base material. Its penetrating action binds those unstable elements, creating a stable foundation for the subsequent topcoat. Typically, a recoat interval of around 2 hours is used before applying a topcoat, with full curing in about 7 days under normal conditions. Always follow safety protocols when working with asbestos‑containing materials.
