DIYUK

Why we love it

Extreme heat resistance guarantees durability.
Permanent stone-hard seal prevents leaks.
Superior adhesion on various surfaces.

Main Highlights

EXTREME HEAT RESISTANCE UP TO 1500°C: Engineered for the harshest environments, this silicate-based formula withstands direct flame and continuous temperatures of 1500°C (2732°F). Far superior to standard red automotive silicones (max 300°C), it is the ultimate solution for sealing joints in wood-burning stoves, multi-fuel fires, pizza ovens, and industrial flues.
PERMANENT "STONE-HARD" VITRIFICATION: Unlike rubbery gaskets that degrade, this sealant cures to a rigid, rock-hard ceramic mass. Through a unique vitrification process, it bonds physically with masonry and metal to form a hermetic, smoke-tight seal that prevents dangerous carbon monoxide leaks and maintains flue draught efficiency. Note: Designed for static joints; does not remain flexible.
SUPERIOR ADHESION TO MULTIPLE SURFACES: formulated to bond aggressively to cast iron, mild steel, stainless steel, firebrick, concrete, stone, and clay. Perfect for sealing flue spigots, fixing loose firebricks, bonding ceramic glass tape, and sealing register plates.
PROFESSIONAL GREY/CHARCOAL FINISH: The thixotropic (non-slump) paste applies black and cures to a discreet, matte dark grey/charcoal that blends seamlessly with cast iron stoves and flue pipes. This ensures invisible repairs that maintain the aesthetic of your hearth.

High Temperature Silicone Sealant Heat Resistant to 1500°C, Flues, Stoves, Glass - DIYUK®

TITANIUM PRO

Why we love it

Extra-hard and durable finish.
Exceptional temperature resistance.
Versatile application uses.

Main Highlights

Odourless and ready to use, this flexible, halogen free silicone sealant is heat resistant to 1500ᵒC and reacts with atmospheric moisture to form a durable flexible seal. Ideal for high temp applications such as sealing connections between single skin flue pipes and can be used outside on the Flashing.
Colour: Dark Grey (Black on tube). Temperature resistance: up to 1500 ᵒC
After the final solidification, slowly heat the sealant up to +250 °C. As the result of heating, the mass will turn dark grey and become extra-hard. Limitations: Not suitable in moving joints and in contact with materials that expand or contract when exposed to temperature. Unheated product is not waterproof and will spread in a wide joint.
Suitable on natural stones. Insulation of joints and filling of cracks in chimneys, ovens, fireplace and stoves. Adheres to metal, stone, brick and concrete
Apply sealant in the joint by repeatedly and evenly pressing on gun trigger and smoothly dragging the nozzle along the joint. After application, smooth the surface with a rubber silicone scraper or putty knife and remove excess material. In some cases, it is more convenient to use plaster spatula.
