22 Lbs Castable Refractory Cement Mix - 3200°F High Temp, Heat & Fire Resistant for Pizza Ovens, Fireplaces, Forges, Kilns, Stoves - Build & Repair Mortar (22LB)

Refractory Concrete Mix (22 lb Ready-Mix Yield)​​​​ ​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. Refractory Cement: Simplified Installation Guide​1. Preparation​：Ensure power tools & vibrators are functional.Prepare anchors, insulation, and connectors. ​Pro Tip:​​ Use a forced-action mixer + high-frequency vibrator. 2. Mixing​： ​Dry Mix:​​ Combine all dry materials + small additive bag (3-5 min). ​Wet Mix:​​ Add ​8% water​ gradually → blend 5 min.Adjust water minimally if needed (avoid over-wetting!) ​Temp Range:​​ 10°C to 30°C (50°F to 86°F). 3. Pouring & Compaction​：Pour:​​ Layers ≤400mm (15.7") thick. ​Vibrate Immediately:​​ Use immersion vibrator rod (plate vibrator for floors). ​4. Demolding & Curing​： ​Demold at 24 hours.​​ ​Cure Naturally:​​ 3-4 days before firing. ​Firing Window:​​ Start kiln/furnace ​between Day 4-15​ (delays reduce lifespan!).

• Multifunctional Expert for High-Temp Applications:​​ Mold custom fireplace/stove parts via vibrocasting, pour seamless brick linings, or expertly repair pizza ovens, kilns, forges & stoves. (Achieves full strength and performance ONLY through proper post-installation heat treatment & curing).
• ​Product Function:​​ For use in ​forming non-standard bricks​ (e.g., in irregular oval, tapered, hexagonal, square, cylindrical, trapezoidal, diamond-shaped positions, etc.). Also suitable for ​repairing large fissures and deep holes​ (performs best on holes deeper than 1.2 inches / 3 cm). ⚠️ WARNING:Not suitable for use as a bricklaying mortar. ​​ (If this is your intended use, please do not purchase.)；Perfect for both professional contractors and DIY enthusiasts.
• Withstands Extreme 3200°F Heat - Superior Insulation:​​ Engineered for maximum thermal efficiency in pizza ovens & forges. Resists sustained temperatures up to ​3200°F (1760°C)​​ to lock in heat, ensure even cooking, and boost energy savings.
• Combats Cracking & Thermal Stress:​​ Forms durable, high-strength bonds that actively minimize cracks and gaps caused by thermal expansion/contraction. Guarantees structural integrity and significantly ​extends the lifespan​ of your high-heat appliance.
• Adhesive included in a separate pouch.​​ Combine with the main mix, add water, and stir – it’s that easy! ​Crucial Benefit:​​ Each 22 lbs bag comes with an airtight-sealed, separate pouch of powerful enhancer - protecting its active properties from moisture/air exposure to ​unlock peak.
