CT1 - Building Sealant & Adhesive Snag Tube for Virtually Any Material (Clear Twin Pack)

I am simply delighted with CT11! I used it to fix heavy planters onto a wall, and the results are absolutely wonderful. Here is why I highly recommend it: Incredible Hold: It holds the planters extremely firm against the wall. Once set, they don’t move at all. It gives you real peace of mind. No Mess: The texture is perfect. It doesn't run or drip during application, making it very clean and easy to work with. Fast Drying: It cures and dries remarkably fast, which is excellent for outdoor projects. This is a top-quality product that does exactly what it promises. I love it and will definitely buy it again

CT1 Grey TRIBRID® is an excellent sealant and adhesive. It bonds extremely well, applies smoothly, and cures to a strong, flexible finish. I used it for sealing and bonding on multiple surfaces, and it held firmly without shrinking or cracking. The grey color looks clean and professional, and it works well even in damp conditions. Very versatile, high-quality product that performs exactly as advertised. I’d definitely use this again for future jobs.

CT1 can’t go wrong with it it’s very durable and seals really well. The only downside is that it takes a lot of use to get the hang of using it as it can be quite unforgiving so best to have a bit of practice first but once you’ve mastered it it’s so much better than ordinary silicon sealant.

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.

Great product. Very effective.

This is an alternative to silicone sealant and most construction adhesives. It’s got fantastic grip and adhesion and you can apply it in damp conditions if you have to. It’s not cheap but it is very, very good at what it does. It’s what construction professionals use. It’s not as easy to clean up as silicone - it’s much stickier so getting a clean bead without a thin layer of residue is trickier than with silicone, but it’s a much better product - unless disassembly is really important. It also lasts a long time in the tube. The nozzle will get clogged, but you can just remove it and poke out the dried flexible plug from the outside end, and what’s left in the tube can be used as normal even several months later. It comes in a range of colours and doesn’t yellow over time. When used for sealing a bath, the white stuff does discolour, but don’t confuse dirt with discolouration - it cleans up perfectly white. I’ve used it for lots of things, including glueing thick limestone tiles to tile-backer board for a removable panel in front of my toilet cistern. Because it remains flexible, it’s ideal for this sort of thing. There are lots of videos about it on YouTube which means that a lot of people are going to end up in difficulty removing bodged DIY jobs. I’ve even used the clear stuff for mending shoes - it’s that strong and flexible! It sticks really well to pretty much everything - except natural rubber

Good strong adhesive, Used on caravan and does the job, Dry's in about 45 minutes, Application is easy and smooths out very well. Colour is white and did not cause any mess.

Excellent produit...

Lo estoy aprovechando para pegar cosas dentro del agua y en otros sitios con diversos materiales , funciona muy bien.

Not as good as advertised

Great stuff. Used to waterproof and seal wiring access plug in an outdoor fountain basin. Immediately waterproof and can be submerged indefinitely.

The product might be great but it is really hard to pay $25 dollars for something that you have to go buy something else to use it. I purchased 2 tubs and both tubs had no top with them. When I went back and read a few reviews I noticed that others said the same thing. So unfortunately after waiting all the time to get them and paying a lot of money for them, I got to spend more money to buy a product that had the top with it so I could use the top from the product. So total the tubs cost me $32 each.
