## Summary description

Soudal SIL SOU PIEC is a 310 ml high-temperature silicone sealant designed for sealing furnaces, stoves, fireplaces and exhaust flues. Provides heat-resistant, flexible joints that resist temperatures common in heating appliances. Suitable for sealing gaps, repairing cracked seals and ensuring gas- and smoke-tight connections in domestic and light-commercial heating systems.

## Long description

Soudal SIL SOU PIEC 310 ml is a high-temperature silicone sealant formulated for use on furnaces, stoves, fireplaces and exhaust flues. The product creates flexible, heat-resistant joints that withstand temperatures commonly encountered in domestic and light-commercial heating appliances. It is intended for sealing gaps, repairing cracked seals and ensuring gas- and smoke-tight connections where reliable thermal and chemical resistance is required.
Advantages
The sealant cures to a durable, flexible silicone that maintains adhesion to metal, masonry and refractory surfaces at elevated temperatures. It resists thermal cycling and retains sealing performance under repeated heating and cooling. The neutral curing formulation limits corrosion on metal substrates and reduces odour during application compared with acid-curing alternatives.
Suitable for
 Sealing joints and connections on wood, pellet and coal stoves
 Repairing cracks in furnace and fireplace seals
 Sealing exhaust flues, chimneys and stove pipe joints
 Creating gas- and smoke-tight barriers around appliance interfaces
Key specifications
 Volume: 310 ml cartridge
 Product type: high-temperature silicone sealant
 Heat resistance: suitable for temperatures typical of domestic heating appliances (high-temperature rated)
 Curing: neutral cure silicone that forms a flexible rubber seal
 Compatibility: adheres to metal, masonry and refractory surfaces
 Application: manual or gun-applied from cartridge
How to use
Ensure surfaces are clean, dry and free of loose material, oil or soot before application. Cut the cartridge nozzle to the required bead size and apply with a standard sealant gun, pressing the sealant firmly into the joint to ensure full contact with substrate surfaces. Tool the joint within the manufacturers skin-formation time to obtain a smooth finish. Allow the sealant to cure fully before exposing the area to high temperatures; follow safety precautions and ventilate the space during first heating cycles to dissipate any transient curing emissions.
Usage recommendations
Use for indoor heating appliances and light-commercial systems where a heat-resistant, flexible silicone seal is required. Do not use on surfaces that will be continuously immersed in water or on joints that require paintability. For best results, test adhesion on a small area if the substrate is coated or has an unknown composition, and follow local codes for appliance sealing and chimney work.
