NO TOPS WITH PRODUCT
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.

Geniale Dicht und Klebe Masse. Sonst müsste ich immer nach den gängigen Marken suchen und dabei gab es eine Tabelle...was man wofür verwenden darf. Die Zeit und Nerven kann ich mir nun sparen. Ich verwende CT 1 für fast alles.Überwiegend verwende ich es für mein Boot und Wohnmobil.Ct 1darf in keiner Werkzeugkiste fehlen.

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.
