Review: Absolutely brilliant! Perfect for heavy outdoor planters - 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 Review: ultra strong, ultra flexible professional construction adhesive - 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 ## Features - Contains sensitizing substances.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Absolutely brilliant!
