Your High-Temp Multifunctional Solution for Building & Repair
⚠️ WARNING:Not suitable for use as a bricklaying mortar. (If this is your intended use, please do not purchase.);
Engineered for Demanding Applications:
premium refractory concrete mix designed for three core high-temperature functions:
1. Vibrocasting Custom Parts: Mold precision fireplace inserts, stove components & refractory shapes.
2. Pouring Seamless Linings: Create durable brickwork linings for kilns, furnaces & ovens.
3. Repairing Masonry : Restore cracks/gaps in pizza ovens, forges, boilers & all heating units.
Critical Performance Note:
Refractory concrete requires controlled heat treatment (drying + firing)to achieve full strength and thermal stability. Strict adherence to the manufacturer's heating procedure is essential for optimal results and longevity.
Yield: 1 bag = 22 lb of ready-to-apply refractory concrete.
