Rated 5 out of 5 by from Best jointing compound I brought this due to it being fairly cheap and had seen the reviews about it. Must say I haven’t stopped buying it since. Very easy to use and remove excess off fittings. Highly recommended

Rated 5 out of 5 by from It just works. I was having major problems sealing an under-sink water filter... the type with 3 plastic cartridge holders. Smeared some of this on the threads (with the help of a toothbrush) and it was sorted. Tad expensive, but would easily pay for itself if I was a professional plumber, just in time saved.

Rated 5 out of 5 by from Excellent Jointing Compound Needed a new tub of jointing compound and got this on the basis of the previous reviews. Particularly liked the idea that it's soft setting. So far I've used it on about a dozen compression joints and tap ends, and am very pleased with it. Easy to use, easy to remove surplus from outside of joints, no leaks, etc. Very happy to recommend.

Rated 5 out of 5 by from Great product This is a must have for any plumber or diy'er. If you make a dry compression joint you are a psycho lol

Rated 5 out of 5 by from Awesome Love this paste. normally buy center brand but got this in a hurry. Tried Screwfix cheapest paste which I quickly brought back because it was terrible and changed for this as the really cheap one is very hard. This paste however, is very soft and easy to apply, no leaks on my joints and I love the size of the pot which is in a smaller handy size pot.
