TEC 7 Sealent 310ml (Brown)

Tec7 Sealant is the industry-standard, professional-grade MS polymer adhesive and sealant engineered to conquer virtually any bonding, sealing, or mounting challenge. Celebrated for its unique "all-in-one" chemical composition, this heavy-duty brown sealant replaces traditional wood glues, polyurethane sealants, silicone sealants, acrylic caulk, and butyl rubber sealants in a single cartridge. It comes highly recommended for construction contractors, carpenters, roofers, and DIY enthusiasts who require an industrial-strength product that blends seamlessly with wood tones, brickwork, and dark finishes while curing reliably under any conditions—even underwater.

Why Choose Brown Tec7 Sealant?

• Unrivaled All-in-One Performance: This versatile compound simultaneously functions as a high-strength structural adhesive, a permanently flexible joint sealant, and a waterproof filler. It simplifies inventory on-site, allowing you to move seamlessly from mounting heavy external fixtures to sealing perimeter joints.

• Bonds Seamlessly to Wet and Dry Surfaces: Engineered with an advanced MS polymer matrix that actively displaces moisture. It can be applied directly to damp substrates, wet masonry, leaking roofs, and even completely submerged surfaces, providing an instant waterproof seal during emergency weather repairs.

• Permanently Flexible and UV Resistant: Formulated to withstand severe structural movement, vibration, and thermal expansion without cracking or peeling away from joint borders. It boasts exceptional resistance to harsh UV radiation, extreme weather conditions, mould growth, and household chemicals.

• Instantly Paintable and User-Friendly: Unlike traditional silicone sealants that repel finishes, Tec7 can be painted immediately after skin formation with almost all modern water-based and oil-based paints. It is completely odourless, solvent-free, non-toxic, and safe to use in confined interior spaces.

• Flawless Multi-Substrate Adhesion: Delivers immense mechanical bonding strength without requiring separate primers, making it the perfect choice for:

  • Sealing and bonding timber, window frames, door casings, and wooden fascia boards

  • Mounting structural panels, skirting boards, dark window sills, and heavy mirrors

  • Repairing roofing leaks, gutter joints, valley linings, and brown external brickwork
