The FirePro Plus Ablative Coating Paste is a fire-rated, ready-to-use paste designed to fill, seal, and protect mineral fibre panels used in firestop systems. Formulated with a durable polymer system, inert fillers, and non-halogenated fire retardants, it resists flame spread and enhances the performance of coated panels.
Ideal for applications where surfaces are uneven, the paste can both fill and coat to create a smooth, uniform finish. It can be applied in layers of up to 10mm per application and dries to a flexible white surface that can be overpainted if required.
When used during mineral fibre panel installation, the cured coating reduces delamination and increases surface stability, making it ideal for use with adhesives and fixing sealants.
