CT1 Exterior Adhesive Sealant Clear is a high-performance hybrid polymer adhesive and sealant designed for demanding aquatic, pond and exterior applications where a strong, permanent and watertight bond is essential. Engineered for professional pond builders, koi keepers and aquatic installers, CT1 can bond and seal materials even when applied underwater, making it an ideal solution for pond liner repairs, waterfall construction, filtration installations and structural aquatic sealing.
Formulated with advanced TRIBRID® hybrid polymer technology, CT1 provides exceptional adhesion to pond liners, rubber, EPDM, PVC, fibreglass, stone, concrete, brick, metal, glass, ceramics and plastics commonly used within pond construction and aquatic landscaping. Its solvent-free and 100% VOC-free formula ensures it will not shrink, crack or react with surrounding materials, helping maintain long-term watertight integrity in koi ponds, wildlife ponds and decorative water features.
The clear formulation allows for discreet repairs and invisible sealing work where aesthetics matter, making it particularly suitable for visible aquatic installations, pond edging, window panels and exposed structural joints. CT1 acts as a multi-purpose replacement for traditional silicone, mastic and construction adhesives, providing a reliable all-in-one solution for both emergency pond repairs and professional installation work.
