OB1 Black HeatProtect Fire Cement 1200°C - High Temperature Heat Resistant Sealant for Stoves, Fireplaces, Ovens & Chimneys.

Extreme Heat Resistance Up to 1200°C - Forms a hard, durable, high-temperature seal ideal for stoves, flues, fireplaces, ovens, and chimneys; perfect for areas exposed to intense heat. Creates an Instant, Heat-Cured Seal - Applies as a paste and dries to a solid, non-flexible seal. When first heated, increase temperature gradually to ensure proper curing and avoid bubbling. Reliable Performance Within Recommended Conditions - Best applied between +5°C and +40°C, and frost-resistant during transport down to -15°C. Avoid use on damp or frozen surfaces for optimal results. Proper Surface Prep for Best Adhesion - Substrates must be clean, dry, and free from dust or grease. Slightly moisten very porous surfaces before applying; OB1 Multi Surface Cleaner can help smooth and finish joints before curing. Easy Application & Cleanup - Supplied in a cartridge with a precision nozzle for controlled application. Uncured material can be cleaned with OB1 Multi Surface Cleaner; once cured, removal must be done mechanically. Material Compatibility Notice - Not suitable for PE, PP, PC, PMMA, PTFE, soft plastics, neoprene, bituminous substrates, or areas with continuous water exposure. Shelf life up to 9 months when stored unopened between +5°C and +25°C. CONTENTS - 1 x OB1 HEAT PROTECT SEALANT BLACK 290ml with Nozzle, Weight: 6.38E-4 pounds, Manufacturer: OB1
