Earthcore Mortar

Product Shown: Isokern® EARTHCORE MORTAR - Accessories Collection

Earthcore Mortar adhesive is a thin-set masonry adhesive used for interior or exterior use. It is an approved adhesive for Isokern® Fireplace Systems and DM chimney components. Earthcore Mortar is supplied dry in 50 lb. pails.

Properly mortared firebox and smoke dome assembly requires approximately 5 gallons (dry measure) of ECI Mortar. Earthcore Mortar is not intended to create a mortar joint of any thickness for leveling purposes – instead, the supplied shims should be used.
