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.  ECI Mortar is supplied dry, in either 15 pound or 50 pound 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.

Notes:

• General uses include ceramic tile, fabricated and cast stone products.
• Do not mix Earthcore mortar with spirits or anti-freeze agents.
• The maximum recommended mortar joint thickness in Isokern components is 1/4".
