CT1White TRIBRID® Multi Purpose Sealant & Adhesive - 290ml

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 CompatibilityOne 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-FreeUsed 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 ResistanceI 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 BlueThe 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-freeHighly recommended for both professionals and serious DIYers.

This stuff is great - use it as glue when walls are damp - is fantastic

Good product & I'm happy with the darker colour as it matches my worktops. Nozzle was not supplied

Great stuff. Second time purchasing

My go-to sealant.Easy to apply and smooth, sticks to virtually any substrate and there is no obnoxious curing smell.More expensive than other brands but well woth the extra cost .

All as it said

Have seen Geoff use this brand, bought to fit shower screen and seal round the bath.Comes out smoothly, seems to smooth off more easily (thicker) makes a good finish.Very strong when cured. Bright white. Quick drying.Although this isn't grip and bond. Does seem to also grip and bond to a degree., stuck a board down with it.I'll always now use this brand.

Seems really good adhesion, time will tell how effective it will be long term.
