Coleman MORTAMIX Mortar Mix 25 Pound Bag

Product Description

The COLEMAN MORTAMIX is a pre-mixed mortar compound packaged in a 25-pound bag, designed for use in HVAC, fireplace, and masonry repair applications. Mortar mix of this type is used to seal, bed, and set refractory or masonry components such as firebox liners, flue tiles, and chimney crowns. It arrives pre-blended, reducing on-site mixing time and helping ensure consistent mix ratios. Installation is typically performed by HVAC technicians or masonry contractors working on combustion appliances and venting systems.

This mortar mix is suited for residential and light commercial masonry work involving high-heat or refractory environments. Common applications include setting firebrick, repairing furnace or boiler fireboxes, sealing chimney joints, and patching masonry around combustion equipment. The 25-pound bag format is practical for single-job or small repair work where minimizing waste is a priority.
