Applications of CT1: The Ultimate Hybrid Sealant & Adhesive

Released On 29th May 2025

CT1 by CTEC is a revolutionary TRIBRID®‑based sealant and adhesive, engineered to outperform traditional sealants in strength, flexibility, and durability. Its unique chemistry makes it suitable for a breadth of challenging applications—here’s an in‑depth look at how CT1 can solve your toughest bonding and sealing problems.

1. Construction: Sealing Cracks & Holes

Versatile Substrate Compatibility
Bonds flawlessly to concrete, brick, stone, plaster, metal, wood, and plastics—no primer required.
 

Crack Injection & Repair
Simply force CT1 into gaps with a standard caulking gun. Once cured, it forms a rigid, load‑bearing seal that won’t shrink or crack.
 

Fast Grab & Load Capacity
Initial tack in seconds; can support up to 30 kg/cm² after just 60 minutes, eliminating the need for mechanical fixings in many scenarios.
 

Shrink‑ & Sag‑Free
Unlike polyurethanes, CT1 cures without bubbling or shrinking, ensuring long‑term structural integrity.
 

Pro Tip:
For hairline cracks, widen the gap slightly (to about 5 mm) with a cold chisel for maximum sealant penetration and bonding.

2. Roofing: Waterproofing Gutters & Flashings

Rain‑Ready Application
CT1 adheres to moist or even flooded surfaces—ideal for emergency patching of leaking gutters, valleys, and flashings.
 

UV & Weather Resistance
Cured CT1 stands up to extreme UV exposure, freeze‑thaw cycles, and temperature swings from – 40 °C to + 90 °C.
 

Joint Sealing
Perfect for sealing overlaps in metal profiles and roof panels to prevent water ingress.
 

Maintenance-Free Solution
Once cured, CT1 remains elastic, accommodating thermal expansion without cracking.
 

Installer’s Note:
Clean surfaces of debris and loose rust, but surface water won’t compromise adhesion—apply even under a light drizzle.

3. Marine: Underwater & Boat Repairs

True Underwater Bonding
CT1 cures completely underwater, making it a go‑to for sealing hull cracks, deck fittings, and through‑hull connections.
 

Chemical & Saltwater Durability
Resistant to diesel, petrol, hydraulic oils, and saltwater corrosion.
 

Flexible Yet Strong
Absorbs vibration and hull flex, preventing bond failure in rough seas.
 

Single‑Component Simplicity
No mixing—apply directly from the cartridge to save time on deck.
 

Safety Reminder:
Ensure minimal movement of the repair area during cure (typically 24 hrs for full strength) to optimise bond integrity.

4. Kitchens: Food‑Safe Countertops & Sealing

Food‑Contact Certification
Cures to a non‑toxic, inert sealant compliant with major food‑safety standards.
 

Heat & Steam Resistance
Withstands temperatures up to 90 °C, ideal around sinks, hobs, and splashbacks.
 

Mould & Mildew Inhibition
Formulated to resist fungal growth—crucial for hygiene in wet kitchen zones.
 

Paintable & Decor‑Friendly
Can be over‑painted with water‑based or solvent paints to match cabinetry and tiles.
 

Design Tip:
Use a matching CT1 colour (e.g., white, beige, or grey) to create seamless joints between countertops and backsplashes.

5. Pools: Leak‑Proof Sealing Without Draining

No‑Drain Technology
Apply CT1 directly to leaks in pool walls, tiles, and skimmers—even when fully submerged.
 

Chlorine & Chemical Resistance
Stands up to pool sanitizers and fluctuating pH levels without degradation.
 

Elastic Cure
Accommodates ground shift and water pressure changes, maintaining a watertight barrier.
 

Longevity
Once cured, seals remain effective for years, reducing costly pool emptying and resurfacing.
 

Maintenance Advice:
For optimal adhesion, brush away loose scale or algae around the leak before applying CT1.

Conclusion

CT1’s TRIBRID® Technology delivers unparalleled performance across a spectrum of demanding environments—whether you’re sealing structural cracks, repairing a leaking roof, or making urgent marine and pool fixes. Its single‑component ease, combined with solvent‑free, low‑odor formulation, makes CT1 the professional’s choice for durable, maintenance‑free sealing and bonding.
