Fire cement is used to seal joints and repair cracks in stoves, flue pipes, fireplaces, and boilers. It bonds to firebrick, masonry, blockwork, and clay, creating a smoke-tight seal that holds up under repeated heating and cooling cycles. Replace or top up the cement when cracks appear around seams or where components join. ✅ Compatible with: Wood-burning stoves, multi-fuel stoves, flue pipes, open fireplaces, back boilers, pizza ovens, and any solid-fuel appliance requiring heat-resistant sealing compound 🔧 Specifications Size: 1kg tub Colour: Black Material: Ready-mixed refractory cement Heat resistance: Up to 1250°C (continuous) Shelf life: 12 months sealed, stored between 5–25°C SKU: TT-20K01BL Part type: Fire cement / refractory sealant Apply directly from the tub with a trowel or spatula to a clean dry surface. Allow to air dry before the first firing, then cure gradually over several hours. Minor cracking after the initial firing is normal — a second application resolves this.
