Which jointing compound

[bsr]

Hi All

Clearly I need to remove and remake these joints on the sink. They are currently made dry. What would you prefer to stop leaks? I have:

• Silicone sealant
  
• A bit of old Geocel plumber joint
• Manky old tub of Plumbers Mate

Mayb I should do a poll

Silicone

Seals, if good quality should seal fully on good surfaces like stainless steel sinks, if tightened properly.
But just some clear silicone will do perfectly on each side of washers (or Plumbers Gold or CT1 or Tec7 if you wanted extremely strong sealant)

Strip it out and clean everything with hot soapy water and remove all the debris and scum. Once everything is dry & nice and shiny then refit and nip it up, it shouldn't really need anything. Silicone on those seals & surfaces can actually make the seals move and misalign if tightened too much.

One drawback is it's a manufacturers own waste so they're not normally the best of stuff.

Thanks, silicone it is.

They are nice and tight. It's one of these sinks made out of stone dust.

Silicone all the way. I've owned a tub of Plumbers Mait for 15 years and I'm still yet to find a good use for it. Might be a bit dry by now, come to think of it...

Silicone worked well, thanks.

On sinks I'd just use the supplied seals, but then it depends on the quality of the manufacturer and wherever in the world they hail from! When replacing, it's mcalpine so quality is there.

I have to say though, as I've done before, on basins, for me it's mait all the way - first time every time. Tried silicone and when testing immediately (cos of time constraints), some have leaked and then you're into cleaning it off and starting again!
