The UTILM 30-1041 is a non-freezing furnace cement formulated for high-temperature bonding and sealing applications in residential, commercial, and industrial heating equipment. Part of the DO-ALL+PLUS Series by Utility Manufacturing, this 1-gallon container delivers a durable adhesive compound engineered to maintain strength and adhesion under sustained heat exposure. The non-freezing composition keeps the product workable in cold storage conditions, reducing the risk of freeze-related waste between jobs. Licensed heating and mechanical contractors rely on this type of cement for sealing firebrick joints, metal-to-masonry transitions, and refractory surfaces in furnaces and stoves.
This furnace cement is suited for repair and installation work on wood stoves, coal stoves, gas furnaces, oil furnaces, and other solid-fuel or combustion heating appliances. It bonds effectively to firebrick, metal, and masonry substrates, making it a practical choice for both new installations and field service repairs. The 1-gallon size is appropriate for larger sealing jobs or for contractors who need a consistent supply on hand across multiple service calls. Its non-freezing sub-type designation makes it practical for use and storage in unheated shops or service vehicles in colder climates.
Designed for use with furnaces, stoves, and other high-heat combustion appliances requiring firebrick, metal, or masonry sealing and bonding.
Application is typically performed by licensed HVAC technicians, plumbers, or masonry professionals working on combustion heating appliances. Allow the appliance to cool completely before applying furnace cement to joints or seams, and follow the manufacturer's cure schedule before returning the unit to service. Consult applicable local codes, including the International Fuel Gas Code (IFGC) or International Mechanical Code (IMC), for requirements governing refractory repair on combustion equipment. Wear appropriate PPE when handling cement compounds in enclosed spaces.
