Our gypsum based fire resistant mortar creates a perfect seal around cables, pipes and ducts through walls, ceiling and floors. Just add water to the powder and it's simple to use, with no priming necessary and easy application for a smooth finish.

Fully set within one hour, the compound requires up to 30 days to cure - where it expands to tightly fill the space - before it is fully fire resistant to then prevent the spread of fire and smoke through openings in fire rated walls and floors, including openings formed around building service penetrations.

The PFP FR EX fire resistant mortar will also maintain the acoustic design performance of surfaces. Where plastic pipes pass through the mortar, our pipe wraps should be used and can be easily added through the mortar and resealed with further mortar. Supplied in a 20kg bag, the mortar is easy to sand or drill, dries an off-white colour and is suitable for painting once cured.

Our fire resistant mortar is CE Marked to Class EI 240, meets the requirements for Class A1 according to EN 13501-1, and has been independently tested according to EN ISO 10140-2:2010. Suitable for walls and floors of concrete, brick and gypsum, It's best used with our fire batt boards.
