Brilliant adhesive+sealant. !!!
This adhesive + sealant is absolutely brilliant, it's got a very good grab, I had to drill a hole through my wall but unfortunately the brickwork outside got damaged, I purchased some brick damage cover's then used this to stick and seal them, did the job perfectly when you stick something with this believe me it does not shift, this is worth the money it's quality. !!!

Easy to use sticks well
Excellent product and good value. It sticks well and seals joints. Whatโs not to like. It was a good colour match to the wall panels I was fixing with it.

Very sticky, just follow the instructions.
Very sticky. I applied five globs to the back of a garden mirror and it stuck very well to brickwork. Used a lollipop stick to apply the adhesive to avoid it running all over the place. This is the second garden mirror I've stuck, the other being one to wooden trellis. I'm very satisfied with the results.

Has its pros and cons
dont get me wrong the sealant itself is perfectly fine, it is just that quite a lot of sealant exit from the other end, wasting and causing a lot of cleaning on the gun, lucky it was on sale and it is almost half price of the CT1, otherwise I would pay a bit more to steer away from the troubles

Really good product.
Really good stuff. Used to seal a broken shower base. Ignore the reviews about it being hard to work with, itโs absolutely fine. It is a bit thicker than the usual silicone, but itโs still easy to push out of a skeleton tool, as well as mould afterwards to whatever shape you need. It does take a bit to cure, but not sure if itโs any longer than normal silicone products. Would definitely purchase again, did the job perfectly.

Polyurethane
Resealable tip is very pleasing and the tube itself high quality. I pumped countless tubes of caulking. The "Hybrid Polymer" proclamation was new to me. Everybody wants to be unique. This is polyurethane, not silicone. Like silicone, it comes in a plastic tube and pumps out with a high sheen, but its similarities to silicone end there. This caulking is like any other high quality polyurethane based caulk. It is sticky and does not like to be worked. It is not overboard like a butyl caulk. Have paint thinner ready if you can't make any mess. It compresses and eventually drips from a drip-free caulking gun. Overall, I am happy.
