Key Features of EvoStik Silicone Sealant

EvoStik silicone sealants are engineered with advanced polymer technology that delivers exceptional performance across multiple criteria. Their low-modulus formulations provide outstanding flexibility, accommodating joint movement of up to ±25% without adhesion loss or tearing. This makes them ideal for sealing expansion joints and areas subject to vibration or structural movement. The products cure rapidly upon exposure to atmospheric moisture, developing a durable, weather-resistant seal that maintains its integrity through countless wet-dry cycles.

Anti-fungal additives incorporated into EvoStik's sanitary silicones provide long-term protection against black mould and mildew, essential for maintaining aesthetic appearance and hygiene standards in damp environments. The sealants exhibit excellent resistance to cleaning chemicals, detergents, and household products, ensuring they won't degrade during routine maintenance. Their superior UV stability prevents discolouration and chalking, particularly important for external applications and areas with high natural light exposure.

EvoStik silicone sealants are available in various colours including clear, white, brown, and grey, allowing for discreet finishing that complements different design schemes. The consistent formulation ensures smooth application with standard skeleton guns, providing excellent tooling properties that enable neat, professional finishing even in difficult locations. Their low odour characteristics make them suitable for occupied spaces, with acetoxy variants offering fast initial cure whilst neutral cure options provide compatibility with sensitive substrates.

Popular EvoStik Silicone Sealant

The EvoStik silicone sealant portfolio includes several specialised formulations designed for specific applications. Their General Purpose Silicone Sealant represents excellent value for standard sealing tasks, delivering reliable adhesion and weatherproofing across a broad range of building materials. This acetoxy-cure formula is ideal for glazing, cladding joints, and general construction applications where rapid curing is advantageous.

EvoStik Sanitary Silicone incorporates powerful anti-fungal technology specifically formulated for wet environments. Available in white and clear variants, this product is the go-to choice for bathroom installations, shower enclosures, and kitchen sealing applications where mould resistance is paramount. Its low-modulus formulation ensures it remains flexible whilst maintaining excellent adhesion to ceramics, enamel, glass, and most plastics.

For applications requiring neutral cure chemistry, EvoStik Neutral Cure Silicone offers compatibility with metals, mirrors, natural stone, and other materials that may be sensitive to acetoxy formulations. This professional-grade product provides excellent adhesion without corrosion or staining risks, making it suitable for high-value installations where substrate compatibility is critical.

Safety and Compliance

EvoStik silicone sealants are manufactured in compliance with relevant UK and European standards, ensuring they meet the performance criteria expected by professional specifiers and building control authorities. Users should always consult the product-specific technical data sheets and safety data sheets available at Tooled-Up before application. When working with acetoxy-cure silicones, ensure adequate ventilation as acetic acid vapours are released during curing. Always wear appropriate personal protective equipment including gloves and eye protection.

COSHH regulations require proper risk assessment when using sealants professionally. Store cartridges in cool, dry conditions away from direct sunlight, and ensure they remain within their recommended shelf life for optimal performance. Remove old sealant completely before reapplication to ensure proper adhesion. For food-contact areas, verify the product's suitability and compliance with relevant food safety regulations. Dispose of empty cartridges and waste material in accordance with local authority guidelines and environmental regulations.

Frequently Asked Questions

What's the difference between acetoxy and neutral cure EvoStik silicone sealants?

Acetoxy-cure silicones release acetic acid during curing, providing fast initial cure times and excellent adhesion to most substrates. They're ideal for general glazing and sealing applications. Neutral cure silicones don't produce acidic by-products, making them suitable for metals, mirrors, natural stone, and other sensitive materials where corrosion or staining could occur. Neutral cure products typically take slightly longer to cure fully but offer broader substrate compatibility.

How long does EvoStik silicone sealant take to cure?

EvoStik silicone sealants typically skin over within 10-15 minutes in normal conditions (20°C, 50% relative humidity). Full cure depth progresses at approximately 2-3mm per 24 hours. For a standard 6mm bead, allow 48-72 hours before exposing to water immersion or mechanical stress. Curing time varies with temperature, humidity, joint depth, and ventilation – cooler temperatures and lower humidity slow the curing process.

Can I apply EvoStik silicone sealant to wet surfaces?

Surfaces should be clean, dry, and free from dust, grease, and loose material for optimal adhesion. Whilst some formulations tolerate slight dampness, applying to wet surfaces significantly compromises adhesion and may prevent proper curing. Always ensure surfaces are thoroughly dried before application, particularly important in bathroom and kitchen installations where moisture is prevalent.

How do I remove old EvoStik silicone sealant before reapplication?

Use a sharp utility knife or specialist silicone removal tool to cut away the old sealant, taking care not to damage the underlying substrate. Remove all traces of the old sealant – new silicone won't adhere properly to cured silicone. Clean the joint thoroughly with white spirit or a specialist silicone remover, then allow to dry completely before applying fresh sealant. Proper preparation ensures maximum adhesion and longevity of the new seal.

Are EvoStik silicone sealants suitable for external applications?

Yes, EvoStik silicone sealants are formulated for both internal and external use. They provide excellent UV resistance, weatherproofing, and temperature stability from -40°C to +150°C, making them ideal for glazing, cladding joints, and external sealing applications. Their flexibility accommodates thermal movement whilst maintaining weathertight seals. Ensure you select the appropriate formulation for your specific substrate and exposure conditions for optimal long-term performance.
