Rated 4 out of 5 by from Essential and Effective There is a lot to like about this jointing compound. It does the job, no leaks and little waste. The instructions tell you to stir it (which is pretty much impossible) and then to coat the male threads with it, but as most people know it’s actually the olive that seals the joint not the compression, so make sure you coat the olive itself. The supplied brush is pretty much useless. I ended up using my fingers. Still, I have a heating system with no leaks, and that’s a win!

Rated 5 out of 5 by from Paste To all you young plumbs and diy’ers, this is the stuff the professionals use to seal compression joints and not ptfe, easily the best on the market ✌️

Rated 5 out of 5 by from EXCELLENT Used on a leaky brass thread fitting and sealed it straight away, bit messy but excellent results and it doesn't set hard at all.

Rated 5 out of 5 by from The best Joint paste Used sparingly and you won’t have a problem. The paste stays in a liquid form and will easily breakdown the union if required post install. Simply the best.

Do I need to let this cure before I fill the system with water?

I used this when installing new radiator valves, filled the system and ALL of them leaked, had to take it all apart and revert to PTFE tape. I'm assuming the compound therefore needs to cure before use, but it say nothing on the instructions?
Asked by: Davetheplumber2
For LACO Slic-tite there shouldn't need to be a cure time so assuming the application is using pretty standard fluids, pressures, and temperatures it would come down to a few application tricks: 1) The threads should be tapered (ie NPT threads). SlicTite won't work with parallel threads. 2) Enough thread sealant should be applied to fill the entire root of the male threads.

Potable Water

Is this suitable for use on potable water? - i.e. hot and cold water within a home? - I can see its ok for heating but to use on hot and cold water it has to be suitable for potable water which is not clear in the description.
Asked by: EvansHeating
No as it is not WRAS approved.
