SOLIDLAND Refractory Castable - 25 LBS 3056°F High Temperature Refractory Concrete Dry Mix - Casting FireBricks, Panels and Custom Shapes for Kilns,

Designed for: Casting firebricks, panels or special shapes for woodstoves, fireplace hearths and sidewalls and other high temperature applications High Heat Resistance: High-purity alumina (≥65% Al₂O₃) and improved aggregates particle gradation ensures durability in fire pits, forges, and kilns, resisting cracking or spalling under rapid temperature changes Quick Air Hardening: Uniquely incorporates silica fume, reduce water demand, sets rapidly at room temperature (48–72 hours); no heating required. Ready-to-use after curing SOLIDLAND refractory castable can repair carcks firebricks or patch cavities, but vertical applications may require formwork, tape, or temporary bracing to secure the mortar and prevent slumping The aggregate gradation contains 15% coarse particles (0.1–0.2 in/3–5 mm), 15% intermediate particles (0.04–0.1 in/1–3 mm), and 70% fine particles (
