Product Overview
Everbuild Everflex Lead Mate Sealant in Grey supplied in a 295ml cartridge. This low modulus, neutral cure silicone sealant is specially formulated for use with soft metals such as lead, brass, copper, and zinc.
Designed as a reliable alternative to mortaring lead flashing and sheet into brick, stone, or concrete, it provides strong adhesion without causing staining or corrosion. The formulation offers outstanding weather resistance, maintaining flexibility and durability in both high and low temperatures.
Its neutral cure chemistry ensures compatibility with sensitive materials, delivering a long-lasting, watertight joint that accommodates movement and environmental stress.
Ideal for parapet and roof sealing applications, with high performance retained across a temperature range from -50°C to +150°C.
Features & Benefits
- Low modulus neutral cure formulation: Ensures durable adhesion to soft metals without corrosion or staining.
- Excellent adhesion to metals: Bonds effectively to lead, copper, brass, and zinc for lasting, watertight joints.
- Exceptional flexibility: ±25% movement capability accommodates expansion and contraction in building materials.
- High temperature resistance: Performs reliably from -50°C to +150°C without cracking or degradation.
- Low shrinkage: Less than 5% volume loss during vulcanisation ensures consistent joint integrity.
- Excellent weather resistance: Suitable for continuous external exposure with long-term UV and moisture stability.
- Non-staining formulation: Will not mark cement or stone surfaces, preserving appearance around joints.
- Paint compatibility: Resistant to plasticiser migration, suitable for use beneath water-based and solvent-based paints.
- Easy application: Smooth consistency allows for clean, controlled application using a standard sealant gun.
- Cartridge size 295ml: Provides approximately 10.5 linear metres of a 6mm diameter bead per unit.
Applications
- Lead flashing installation: Alternative to mortaring lead flashing and sheet into brick, stone, or concrete.
- Expansion joint sealing: Suitable for joints subject to structural movement and temperature fluctuation.
- Soft metal sealing: Bonds to lead, copper, zinc, and brass without risk of corrosion.
- Weatherproofing: Provides watertight sealing for parapets, roof joints, and external cladding interfaces.
- Panel joints: Effective for weather sealing and joint sealing to pre-formed façade panels.
Installation Guidance
- Surface preparation: Ensure all surfaces are clean, dry, and free from dust, grease, and contaminants.
- Priming: Generally not required, though small-area adhesion testing is advised prior to application.
- Joint design: Minimum width 6mm; depth no greater than width; for joints up to 10mm wide use 5mm depth.
- Application: Cut cartridge tip and nozzle at 45°, apply using a standard sealant gun at consistent pressure.
- Tooling: Smooth the sealant with a spatula or timber piece for best finish; remove masking tape within 5 minutes.
- Cleaning: Clean uncured sealant with white spirit; remove cured material with Everbuild Silicone Eater.
- Limitations: Not for use with bitumen, asphalt, neoprene, or oil-bleeding substrates.

- Hardness: Shore A 20–30 providing balanced elasticity and resilience.
- Tensile strength: 0.6 MPa at break (ISO 8339).
- Elongation at break: >200% ensuring flexibility under joint movement.
- Elastic recovery: >70% (ISO 7389) for sustained joint integrity.
- Movement capability: ±25% for dynamic sealing performance.
- Service temperature range: -50°C to +150°C for all-weather stability.
- Certification: Conforms to ISO 11600 F25LM and EN15651-1 Class F25LM CC.
