## Description

CT1 is a high-quality sealant and adhesive that professionals hold in high regard. Its new TRIBRID® Technology means that it performs extremely well in bathroom applications because bacteria and microbes cannot penetrate its surface. This new triple strength technology has increased CT1's strength by 360%, placing it on top as the world's strongest and most versatile sealant and adhesive. CT1 Grey is just one of many colours available and contains flexible properties that make it perform well in extreme pressure without cracking or losing its initial strength. It offers a unique adhesion to virtually any material and the best part is that you'll never need to add extra fixings to support the bond. CT1's results are long-lasting, dependable, and effective.

Review: Great buy - 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.
Review: Extremely versatile and strong sealant — ideal for every-day DIY and home repairs - 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.

## Questions & Answers

**Q: If I made a mess sealing my shower is it easier to get off than silicone?**
A: CT1 is quite different to silicone.  CT1 is primarily an adhesive . . . but is also used as a sealant and as a filler, it is very versatile.  If you use CT1 to seal the parts of your shower that need to be water proof, i.e., the corners, around the tray, door edges and the like, it will do it just as well as silicone and in my experience somewhat better. I stopped using silicone for this purpose about 7 years ago soon after CT1 appeared.  Silicone is quite ok to use for your shower sealing, but as you may have already discovered if you make a mess of the job you will find difficulty in getting old silicone off neatly enough to do the job again. If you make a mess using CT1 you should wait 24 hours for it to harden right through and then you can carefully cut it out with something sharp like a Stanley knife and you should be able to cut/scrape it all away, not so with silicone. So, here is a tip from someone who has successfully used CT1 on all sorts of jobs . . . . . . would you believe that you can mould CT1 into shape with your finger . . . . but you MUST keep your finger wet, you can pat it into shape and you can repeatedly run you wet finger along a line of CT1 and push it into an even shape . . . .  but the second your finger is dry it will catch and pull out of shape.  Once you have completed your job with CT1 you should not touch it for about 6 hours to give it ample time to partly harden, but then you can run your shower and feel that lovely warm water running over your head and shoulders and body . . . . . oh dear enough of that stuff!  😜

**Q: Can this be used in a fish pond? Is it safe for the fish**
A: Hi there - I have copied the following statement from the CT1 website as it appears your question must have been asked on many occasions! Please see below:

Well CT1 is not a silicone sealant but unique hybrid polymer formulation that is able to stick onto wet surfaces even under water making it the perfect sealant for sealing fish ponds, it contains no solvents so will not contaminate the water extremely aquatic friendly. There have been occasions when the fish have nibbled at the cured CT1 with no adverse effect but with so many species of fish we cannot say that for all species. CT1 has a food safe certificate and is the 100% Eco-Compliant and has an EC1 and EC1 A+ certification.

Hopefully the above statement will help you make your mind up

Regards

Steven

**Q: How do you open this sealant please?**
A: You unscrew the pointed top and using a sharp knife cut the top off  then cut the pointed top to get the width of sealant you require

**Q: Can I use CT1 on cement?**
A: Drilled a hole through a brick wall and filled it with CT1 a builder advised me to use it.

### ⭐⭐⭐⭐ Easy to use
*by R***S on 11 April 2023*

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.
