Schiedel ISOKOAT Chimney Coating System

Isokoat chimney and flue coating by Turner Baker

In old chimneys the mortar joints between the bricks or stonework fail. The mortar becomes porous, turns sandy and crumbles away. Then poisonous fumes, tars and Condensation can all leak out of the flue into the home.

ISOKOAT is applied under pressure and forced into the cracks and fissures, sealing them, re-pointing the joints and strengthening the flue wall. Mineral fibre Reinforcement in the ISOKOAT ensures that the wet material will not pour or leak away through larger cracks, but will be forced into and fill and bridge them.
