CT1 CT1OAK Oak TRIBRID® Multi Purpose Sealant & Adhesive - 290ml

I bought CT1 White TRIBRID® sealant & adhesive because I wanted a reliable product that could handle a variety of materials and tasks — from sealing bathroom joints to fixing a small leak around a window frame. After using it for a few different jobs, I’m impressed with how well it performs and how many situations it handles effectively. When applying CT1, the tube was easy to use with my standard skeleton caulking gun; I cut the nozzle carefully and applied a neat, consistent bead. The product glides smoothly and applies evenly. After smoothing with a damp finger, the finish looked clean and professional — no gaps or air pockets. Once cured, the seal felt solid and waterproof. I tested it on both indoor (bathroom sealant job) and outdoor (window frame) surfaces — the bond held firm under damp conditions, and I’m confident it will resist temperature changes and weather. I also used CT1 to bond a small wooden trim to a tiled wall — it adhered strongly to both the wood and tile without additional fixings. Given the manufacturer’s claim that its special “TRIBRID” formulation bonds to many materials (metal, glass, wood, tiles, concrete, plastics, even fiberglass) and remains flexible yet durable, that versatility matches what I saw in real-life use. Overall, CT1 feels like a premium multipurpose sealant/adhesive that really lives up to its claims — no shrinking, no cracking, and a strong, watertight bond. I appreciate that it’s solvent-free and odourless, which made application easier inside the house. Pros: Bonds strongly and reliably on many materials (wood, tile, concrete, metal, etc.) — handy for versatile DIY jobs. Easy to apply — smooth bead, even curing, no mess if applied carefully. Waterproof and durable — holds up under damp or changing weather conditions. Solvent-free and odourless — suitable for indoor use without strong smells. Good flexibility and no shrinking or cracking after cure. Cons / Things to check: For very fine work, controlling the bead size requires careful nozzle cutting (tiny nozzle tip). For best adhesion, surfaces need to be clean and reasonably smooth — uneven or very rough walls may need prep work. Cure takes some time; avoid stressing the joint too soon after application. Verdict: If you’re looking for a “do-it-all” sealant and adhesive — whether for bathroom sealing, minor repairs, bonding trims, or general home maintenance — CT1 White TRIBRID® is an excellent choice. It saves the hassle of juggling multiple products and delivers a strong, water-tight bond that lasts. I’d recommend it to homeowners and DIY-ers looking for reliability and versatility.

Having used a wide range of sealants over the years—from the budget DIY options to the so-called “heavy-duty” ones—CT1 TRIBRID has firmly earned a permanent place in my toolkit. Whether you're sealing around a shower tray, fixing up leaky windows, or tackling awkward corners, this sealant genuinely does it all. 🛠️ Multi-Surface Compatibility One of the standout features is how well it adheres to virtually any surface. I’ve used it on PVC, metal, glass, and even painted timber—without any primer—and the bond has been solid and durable in every case. It doesn’t shrink, crack, or peel with time either, even under temperature changes. 💧 Totally Waterproof, Anti-Mould & Odour-Free Used it around a shower tray and bath area—absolutely zero mould growth even weeks later. It cured quickly without any unpleasant smell and didn’t attract dust or grime the way silicone sometimes does. The waterproofing is genuinely impressive, and it doesn’t go tacky or gummy. 🔧 Flexibility & Vibration Resistance I used it in a campervan project and was impressed by its ability to handle vibration and movement without breaking its seal. It’s flexible enough to expand and contract slightly with materials, which makes it ideal for long-term projects or exposed applications. 🎨 Aesthetic Finish in Blue The blue variant gives a clean, modern finish—great when you want a pop of colour or need visibility during application (e.g., around flanges or fittings). Smooths out cleanly with a bit of soapy water or tooling spray. Verdict: If you're tired of redoing poor sealant jobs or wrestling with adhesives that promise more than they deliver, CT1 is the upgrade you've been looking for. It’s not the cheapest—but it’s one of the most reliable, efficient, and cleanest multi-purpose adhesives I’ve used to date. ✅ Ultra-versatile ✅ Strong initial tack and long-term hold ✅ Great in wet, cold, or warm conditions ✅ Mould-resistant and odour-free Highly recommended for both professionals and serious DIYers.

Good service and good product. Easy to use but you must let it cure for 12 hours or so. Used on a leaking steel sink that has a split in it. Worked ok but needed to reapply a couple of times. Has reduced the leak but not totally. Think the product it fine but this application is a difficult fix. Will use it on other jobs.

Great product.

This was recommended to fill in a hole in a brick wall, easy to use, colour as advertised and good adhesion. Quality seems decent but time will tell.

Folks, let me tell you, this CT1 White TRIBRID Multi-Purpose Sealant & Adhesive is absolutely fantastic. It's a game-changer, believe me. This product is strong, versatile, and reliable. You can use it on virtually anything—wood, metal, plastic, you name it. It's like the Swiss Army knife of sealants and adhesives. The application is smooth, and it dries quickly, forming a durable bond that's built to last. No more worrying about leaks or weak joints. This stuff holds up under pressure. It's the best, and I mean the best, sealant and adhesive out there. Highly recommended!
