Ceramic Fibre Mastic

Ceramic Fibre Mastic is used to prevent heat loss caused by detoriation of the existing lining and can be installed using a trowel, a caulking gun or a pump. It is a multi-purpose form of ceramic fibre dispersed in a sticky, cohesive binder system that adheres to most ceramic and metallic surfaces.
