CT1 by C-TEC Ireland – The Ultimate Sealant and Adhesive for Every Application

CT1, manufactured by C-TEC Ireland, represents a major advancement in sealing and bonding technology. Powered by patented TRIBRID® Technology, CT1 is not only 360% stronger than traditional hybrid polymer sealants, but also exceptionally versatile, durable, and reliable. It is designed for professionals, contractors, and DIYers who need a high-performance solution that works across virtually all materials and under the most challenging conditions. Whether you are repairing, installing, building, or renovating, CT1 simplifies the process by doing the job of multiple products in one.

TRIBRID® Technology and the Science Behind Superior Bonding Strength

The foundation of CT1’s superiority lies in its revolutionary TRIBRID® Technology, a step beyond older hybrid polymer formulas. This technology enhances strength, durability, and longevity in real-world conditions. Unlike other adhesives, CT1 forms an ultra-strong, flexible bond that remains stable across temperature fluctuations, damp conditions, and even submerged environments. It is scientifically proven to deliver outstanding colour retention, meaning white sealant won’t yellow over time, and clear formulations remain transparent even after years of exposure to light, moisture, and chemicals.

Performance on a Wide Range of Materials

CT1 is known for its ability to bond with an exceptionally broad spectrum of materials without the need for primers or mechanical fixings. Whether the application involves timber, glass, metals, brick, ceramics, concrete, mirrors, or stone, CT1 delivers a dependable, lasting hold. It even performs on synthetic materials and most plastics, with the exception of polypropylene (PP), polyethylene (PE), and PTFE. This flexibility is especially important for tradespeople working on mixed-material jobs, such as kitchens, bathrooms, shop fittings, and marine structures.

Adhesion in Wet and Underwater Environments

One of CT1’s standout features is its ability to work in wet conditions, including underwater. This makes it an essential tool in marine repairs, water tank sealing, and outdoor installations where exposure to rain or humidity is unavoidable. CT1 cures by moisture, not air, which enables it to be applied on damp surfaces without loss of performance. From swimming pools to boat hulls and emergency on-site leak repairs, its underwater application capability sets it apart from conventional sealants and adhesives.

Certified Safety for Food Areas and Allergy-Sensitive Environments

CT1 is both ISEGA-certified and approved by the Norwegian Asthma and Allergy Association (NAAF), making it suitable for environments where health, hygiene, and air quality are priorities. This includes food preparation zones, medical facilities, schools, and care homes. It contains no solvents, no isocyanates, and no harmful emissions, which also contributes to its EC1 Plus A+ Indoor Air Comfort Gold rating – one of the highest levels of certification for low emissions products used in building interiors.

An Eco-Conscious Choice With No Shrinkage, Odour, or Solvents

CT1 is completely odourless and solvent-free, creating a safer, cleaner user experience for both professionals and DIYers. It does not shrink during curing, ensuring a consistent, long-lasting finish. These characteristics are especially useful in enclosed spaces or live environments where fumes and shrinkage might compromise both performance and safety. The product also resists vibration, UV exposure, and microbial growth, ensuring durability over time without discolouration, degradation, or detachment.

Trusted for Marine and Saltwater Applications

CT1’s marine-grade resistance to saltwater, chemicals, and environmental stresses has earned it a strong following in the marine maintenance and boatbuilding industries. It can bond and seal in underwater environments without breaking down, making it ideal for emergency repairs on boats, docks, marine engines, and coastal infrastructure. Contractors working in harsh UK and Northern Irish weather find CT1 especially valuable for its resilience in these demanding conditions.

Colour Stability and Aesthetic Finishing Across All Substrates

Appearance matters in both residential and commercial projects. With CT1, tradesmen and renovators have access to a range of colours matched to the RAL and Pantone systems, ensuring seamless blending with interior design or exterior finishes. White remains pristine over time, while clear remains genuinely transparent. CT1 can be painted over with water-based paints after curing, allowing even greater visual integration without the risk of colour bleeding or inconsistent coverage.

Advanced Certifications for Full Professional Assurance

CT1 is rigorously certified to meet and exceed a wide array of industry standards. In addition to ISEGA, NAAF, and EC1 Plus approvals, it holds the SINTEF ETAG022 certification for waterproofing, confirming its effectiveness in demanding waterproofing applications. It is UKCA and CE marked, ensuring full legal compliance for both UK, Northern Ireland and EU markets. These certifications reinforce CT1’s reliability across private, public, and commercial sector use.

Practical Use Cases for Professionals and Homeowners Alike

CT1 is a favourite among roofing contractors, plumbers, electricians, window installers, kitchen fitters, flooring experts, and general builders. Its ability to perform a range of tasks (sealing, bonding, mounting, repairing) saves time and cost by reducing the need for multiple products. In residential contexts, homeowners use CT1 for everything from bathroom and kitchen renovations to quick fixes on gutters, tiles, and skirting boards.

Ease of Use for Fast and Accurate Application

CT1 comes in a standard cartridge compatible with most caulking guns. Application is simple, even for those with minimal experience. It can be tooled using a wet finger or a finishing tool to achieve a smooth, professional-grade finish. It adheres instantly and sets quickly, even on vertical or overhead surfaces, reducing the need for bracing or clamps. Its one-step application and instant grab eliminate the complexities that come with conventional bonding methods.

Industry Recommendation for Specialist Environments

For environments prone to excessive humidity or mould (such as bathrooms and wet rooms) C-TEC Ireland also recommends using BT1, a specialised variant based on the CT1 formula. BT1 offers superior resistance to mould and fungal growth, delivering even greater longevity in damp spaces. While CT1 itself has moderate resistance to fungal growth, BT1 is the go-to option for the most demanding sanitary environments.
