High-temperature sealant for home improvement and heating repairs, promising durable seals rated to 1200°C. For DIYers and heating engineers who need quick, dependable fixes, OB1 HeatProtect Instant Fire Cement brings confidence when sealing hot joints. Is the instant-setting formulation robust enough for long-term use in demanding heat?
⚡ At a Glance
- • Heat Resistance: Withstands up to 1200°C while maintaining joint integrity
- • Best for: Sealing stoves, flues, chimneys and boilers during repairs and maintenance
- • Not ideal for: Joints that require flexibility or movement due to non-elastic hardening seal
Professional-grade fire cement cures to a hard, non-elastic seal and includes a precision nozzle for controlled application. Instant-setting formulation creates a rapid, durable bond suitable for heat-exposed connections.
Reliable High-Temperature Seals - thanks to 1200°C heat resistance
Formulation resists temperatures up to 1200°C and cures to a hard, non-elastic compound that preserves joint integrity under extreme heat. The hardening chemistry reduces risk of spalling or gap formation during repeated heating cycles.
Maintains secure seals on stoves and flues during prolonged use, helping to prevent leaks and heat loss.
Rapid Emergency Repairs - with instant-setting formulation
Instant-seal chemistry forms an immediate, durable bond on application, designed for quick maintenance tasks and urgent fixes. Rapid set behaviour reduces downtime for heating systems.
Allows fast resealing of leaks and gaps so systems can be returned to service promptly after repair.
Neat, Controlled Application - thanks to precision nozzle applicator
Precision nozzle directs paste into narrow gaps and awkward angles for accurate placement, improving adhesion in hard-to-reach areas. Controlled dispensing reduces waste and the need for excessive finishing.
Reaches tight joints without messy over-application, making installation cleaner for both professionals and DIY users.
