 Use of putty on marble and ABS
Author: Huck

I'm installing a new faucet on a cultured marble sink/countertop, and I'm wondering if it's ok to use plumber's putty or if I need silicone. I've heard putty shouldn't be used on marble because it discolors it, but why would that matter if it's only under the flange where it can't be seen? Is there any other reason not to use it there? I also read somewhere that this warning only applied to marble, not cultured marble, but that was contradicted elsewhere, so I'm not sure what to think.

I also heard that plumber's putty shouldn't be used on ABS pipe. Does anyone know what the adverse effects of that are? I'm having a slight leakage problem in the drainage part, and I think the putty would fix it.

I guess the alternative to putty is silicone, but doexn't that dry out over time and cease to function?

Thanks for any advice,
Huck

If in doubt, use silicon. It doesn't dry out. And I would also reccomend silicon to fix the leak on your drain also.

Putty can leach and discolor, not just where it touches, but the stain spreads. I would use silicon. What abs fitting are you proposing to putty? Putty is usually used under flanges or faucet bodies when installing fixtures, as opposed to a stop leak.

Cheers, Jeff.

i haven't used putty since hector was a pup.
just a couple of days ago i installed a garbage disposal. i had installed the sink about 18mos ago but at the time the customer opted not to put in a disposal. i originally installed the basket strainer with silicone. (all i ever use) when i removed the strainer to install the disposer flange, it came right out. the silicone did not glue it in place, it did not dry out and the seal was perfect.

Packy,
How do you remove the excess silicone that squeezes out when you tighten the sink strainer (or disposal flange)?

In that case I have both of them and they may be "rare and valuable" some day.

Plumbers putty is oiled based and will bleed into any porous material. Even if it is just under the flange it can damage the stone.

I went on a job once that the homeowner had installed a drop in SS kitchen sink with a bead of putty under the rim, it bled real bad and stained the granite although once the sink was removed and it aired out for 3-4 days, the stain disappeared.

The person was very relieved to say the least, that could have been an expensive mistake on his part.

wipe off as much as you can right away and use denatured alcohol to remove the residue. as we say around cape ann, "it works the nuts".
where i really like to use silicone is around the "mack" washer for pop-up drains on those wonderful pedestal lavs. if there is one place that i don't EVER want a leak, it's there. you can't even see the thing, never mind tighten it after the fact.

I use silicone everywhere that I want a perfect long lasting seal. In the rare instance that I want to use a sealer and adhesive in one product I use polyurethane caulk. It takes about 2 weeks to FULLY cure but I used some on a shower door frame over 6 years ago and it is just as good as the year it was installed.

Jeff,

The drain leakage is where the U-shaped part of the P-trap attaches to the elbow that comes off the drain pipe. There seems to be a little piece of the beveled edge of the U part broken off, causing the leak. I tested it with a ring of putty inside the elbow where the U is inserted, and it stopped the leak. I was wondering if this would work long-term, or if the putty would do something to the ABS over time.

Thanks,
Huck

Thanks to everyone for the advice. It sounds like silicone is the way to go. What exactly do I look for at the hardware store? Is this the same stuff used for caulking around bathtubs or is it something different?

Thanks,
Huck

Huck, you need to replace that part of the p-trap. Putty won't work.

Cheers, Jeff.

Where the fixture, (faucet & drain assembly flange) meet the cultured marble use 100% silicone, any hardware store will stock it.

NEVER NEVER USE PLUMBERS PUTTY ON NATURAL STONE. You can read the label as well. It will state not to use on natural stone, Marble/granite/ect..... They do however make a plumbers putty that is made special for natural stone. I am a dealer of stone sinks and we see this issue with stains. Its not easy to get out sometimes impossible. So very careful with anything with an oil based product. Also never clean with harsh chemicals as to this can also damage.
