When to use plumbers mait/silicone sealant
AndyP
When should I be using plumbers mait and when should I use silicone sealant?
Obviously I use silicone for things like round edge of the bath etc.
However, on my new bath, the instructions said to use silicone around the
rim of the waste to seal it to the bath.. I thought I was supposed to use
plumbers mait. The sealant I got from Wickes (their kitchen and bathroom
stuff, which says it's suitable for baths, showers, etc) says it's not
suitable for continual immersion in water, which seems to suggest I
shouldn't use it for the bath. The bloke in Wickes recommended I use their
"external leak sealer and jointing compound" round the waste.. I'm a bit
confused by all this.
As per another post, I'm also about to put a new tank connector into my cw
cistern in the loft. If I want to be really paranoid, would putting some
plumbers mait in there make it less likely to leak, or would it be
pointless?
Thanks,
Andy

it would probably be counter-productive IMHO,just use the washers as
supplied with the tank connector fitting.

Use Fernox LS-X it's great for these applications.

Sadly no washers were supplied (tank connector bought from Wickes - they
sell many different types of washer separately, although it's not obvious
which sort I should use).

Almost never.

Most of the time.

Whenever I've used plumber's mait in any joint, i've ended
up taking it out, cleaning it all off, and using silicone or the
correct washer. I reckon you'd be best to start with silicone
or the correct washer.
AFAICR, Belfast sink wastes need plumber's mait, but
I don't have one so I'm not sure about that.
HTH,
Al

So is there a brand of silicone suitable for total immersion in water - eg
round bath waste? As I mentioned, the stuff I've got (from Wickes) says it's
not suitable for this.

Then it's not silicone. Silicone is always suitable for immersion in water.

I always use Unibond Sanitary Sealant.
Never had any problems on wastes etc.

There are very few places where Mait (stay soft putty) is needed. Basin
wastes is one. Useful also when ceramic is on ceramic to soften the
contact, i.e. basin on pedestal, or WC pan on floor tiles.

Hi,
If it's cheap stuff maybe it has fillers in. Silicone has long been
used for holding glass fish tanks together so the proper stuff can be
used in that way.
cheers,

Silicone sealant is not appropiate for surfaces which need to slide over
one another to seal - e.g. threads.
In every other way, its better than sliced bread, except for toast.

... a disaster. AIUI you should _never_ use linseed oil based compounds
(such as plumbers' mait or boss white) on plastic fittings.
(I'm assuming you mean a plastic cistern, not an old galvanized one.)

Fernox LS-X as already mentioned.

Nah. I cleaned all the plumber's mait off and replaced with silicone when I
installed mine. ;-)

Hmm. Well it definately says it's silicone on the tube. And it definately
says it's not suitable for continual immersion in water. Sounds like there
are different "grades" of the stuff with the Wickes variety being down the
bottom end.

Hi,
Does the oil affect the plastic in any way?
cheers,
Pete.

> Does the oil affect the plastic in any way?
I think it can do, with some types of plastic, possibly by a reaction
with any plasticiser, causing embrittlement. I first came across the
advice in the instructions that came with a Ferham plastic (PVC,
probably) cistern and have kept it in mind ever since.

Ah well, in that case I'm going to have problems sometime in the
future !! Firm believer in Plumber's Mait for traps and the likes.
At least I might now have an idea what was the cause.
As a side question - what is the best way of getting taps to tighten
properly onto the bath or basin; previously you could rely on the
stiffness of the copper pipe to help with this but with flexible
couplings and plastic washers I'm finding it difficult to get taps to
lock properly to the bath, etc.

As you say most on line portals to Usenet are sensible and do not present
really old post simply in the order of month, they use the year and many
actually lock old ones to stop this, Mind you they do not present Usenet as
