Hemway uses advanced hybrid polymer technology that combines the flexibility of silicone, the paintability of acrylic caulk, and the high bonding strength of adhesives, giving you a true all-in-one solution for sealing and fixing. What applications is this sealant suitable for? It’s designed for a wide range of construction uses including expansion joints, perimeter sealing, panel bonding, and general gap filling. Suitable for use on concrete, brick, stone, wood, metal, glass, and most common building materials. Is it suitable for external use and harsh conditions? Yes. The formulation is fully waterproof, UV resistant, non-shrink, and designed to withstand movement and exposure to the elements, making it ideal for demanding site conditions. Can it be painted after application? Yes. Once cured, the sealant can be overpainted with most paints and coatings, allowing for a clean, professional finish that blends with surrounding materials. How easy is it to apply and what is the curing time? It applies smoothly using a standard sealant gun and tools easily for a consistent finish. It skins quickly and typically cures within 24 to 48 hours, depending on temperature, humidity, and joint depth. ## Features - HYBRID POLYMER TECHNOLOGY: All-in-one technology combines the flexibility of dark grey silicone, the paintability of acrylic grey caulk & the high-strength seal of adhesives; ideal for construction, renovation, finishing & fixing. - VERSATILE USE: Delivers an anthracite grey sealant finish on wood, glass, plastic, metal, PVC & concrete, plus compatible with water-based paints; an ideal floor, tile, bath, window, wall, door, shower, toilet, roof & gutter leak waterproof sealant. - ANTI-MOULD & WATERPROOF: Our unique non-shrink formula is anti-mould, waterproof, weatherproof, chemical & UV resistant, offering a durable, long-lasting finish that is resistant against fading & stains. - ECO-FRIENDLY: This adhesive & sealer is more environmentally safe than other silicone alternatives; a solvent-free, odourless, non-toxic & low VOC product.
