Kitchen Sink Caulk got mold

[handyman2020]

Hello All,
I did Caulk around kitchen sink, it was a Lepage regular caulk tube, now after 7 months I see mold around where water usually stays. I think I have recaulk but which caulk to buy so that it doesnt get mold that fast. Any product recommendations.


Thankyou

First you have to remove all the old caulk and treat the seam for mold. Let it dry thoroughly. While silicone caulk is not immune to mold, if done well no moisture will get into it and start the mold up again. Use cleaners with bleach regularly. There are other choices other than silicone, but acrylic/latex is not a god choice. Polyurethane is difficult to apply and smooth, but it is a great window caulk. It will turn yellow outdoors just like others. Just thought I'd throw that in.

If using silicone, watch a YT on the subject where tape and soapy water are used.

Also, if using silicone, be sure to get one made for kitchen/bathroom use that is NOT paintable.

Check your Paint Store for a Mildew Resistant product; it will probaply be marked "Kitchen & Bath"

Maybe try grout?

did the instructions tell you to caulk ? The last drop in sink I did still said to use putty as always.

I never put caulk on/in so it is visible. Raise the sink on some blocking, 3/4" scraps should be enough. Scrape and clean well. Treat with bleach and let it dry. Lay a bead of poly caulk under the sink rim. Far enough from the edge so that it won't squeeze out when lowered.
Apply masking tape to the counter even with the outside of the sink rim.

Carefully lower the sink. pull tape. Check for anything that the tape didn't catch.

whenever you pick up a tube of caulk the little guy on your shoulder should start saying -- are you sure?

Plumbers putty is for setting sink faucets and drain spuds, it also works for sinks.

^^^^ Plumbers putty. Just did a buddies sink as nadogail described. The non staining formula. Black quartz sink, no stains.

Does it clean off? The back of your sink is wet and when our bathroom sinks continuously get wet like that the caulking starts looking dirty too over time. We spray some cleaner on it wipe it down and move on till it starts building up again.

Make sure you give the caulk plenty of time to cure before you let it get wet.

Modern and specialty caulks

Puddy is ok for mounting the sink, but the junction of the counter and the wall will still need caulk. Zeke has it right.

Plumber's putty dries out and gets brittle and cracks. Almost every plumber I used stopped using plumber's putty over 20 years ago. The only one that still used it said it guarantees service calls in 7 to 10 years.
