K-FLEX FIRE EX MORTAR  

K-FLEX FIRE EX MORTAR is a gypsum based mortar material, used to reinstate the fire resistance performance of wall and floor constructions where they have been provided with apertures for the penetrations of multiple services. When mixed with water, the compounds form a highly thermally insulating fire sealing compound to prevent the spread of fire and smoke through openings in fire rated walls and floors, including openings formed around building service penetrations. K-FLEX FIRE EX MORTAR will also maintain the acoustic design performance in walls and floors. K-FLEX FIRE EX MORTAR expands approx. 1% by hydraulic action during curing ensuring a very tight seal around the service penetrations and the surrounding opening apertures.

APPLICATIONS
K-FLEX FIRE EX MORTAR may be used to offer a penetration seal with cables, cable trays, plastic pipes, composite pipes and metallic pipes with and without insulation
- Up to 4 hours fire resistance (integrity and insulation);
- Can be used in wall and floor penetrations to accommodate a variety of penetrating services;
- Easy to use: can be applied by trowel or poured into place;
- Does not need specialist equipment: simple mixing and application tools can be used and cleaned with water;
- Does not shrink on setting and provides a rigid, gas-tight barrier to smoke, combustion and halogen gasses.
