Arc Fire Cement is a ready mixed, air drying, silicate-based material for use as a joint filler and adhesive where high temperature resistance is required, such as pipework and flues in fireplaces, boilers, solid fuel burners, central heating systems and fire backs. It resists to temperatures up to 1250ºC and, when exposed to heat, it dries to a hard, cement–like material with good adhesion to many surfaces.
