Caulk is applied around the perimeter of a kitchen sink to create a watertight seal between the sink and countertop and help hold the sink in place. If water is allowed to leak through the gap around the edge of the sink, moisture can build up and lead to mold growth.
For sealing a kitchen sink, or anywhere water could be present, choose a GE-branded 100% silicone sealant, like GE Tub & Tile Silicone 1® sealant. This sealant is 100% waterproof, permanently flexible and has 7-year mold-free product protection,1 so you can create a lasting, mold-resistant and watertight seal.
If you have to stop or prevent leaks around your faucet, sink, or tub drains, plumber's putty is the product you need.
For a stainless or metal sink (such as those commonly found in kitchens), you'll want to use a silicone-based caulk. For a porcelain sink (more common in bathroom spaces), a latex-based caulk will be a better fit. When choosing caulk, it's also important to select a color that will best suit the space.
Silicone sealant is the best type of caulk for kitchen use. Silicone is waterproof and non-toxic. It is flexible, durable and rarely cracks. It is capable of adhering to a wide variety of substrates, including metal, glass, porcelain and ceramic.
Bathroom sinks: If it's an undermount sink, yes, it must be caulked. This prevents any water from penetrating into the countertop material and cabinetry below. Otherwise, you could get mould.
While plumbers putty is more traditional, silicone caulk is a great modern alternative. Either is acceptable for fixing a drain.

Why sealing kitchen sinks is necessary. Creating a seal around the kitchen sink is a simple step often overlooked by DIYers. Sealing around kitchen sinks or sealing a sink drain with silicone will keep your sink in good condition and prevent future problems.
Make sure the depressed area around the sink drain is also clear of any built-up material. Afterwards, apply a bead of silicone caulk around the drain hole in the sink. Then, apply a second bead along the underside of the drain flange.
They buffer the sound of pots and pans hitting the bottom of the basin, serve as a drainer, and protect dishes and cookware from scratching the finish on your sink. With so many sizes, shapes, and basin configurations available in kitchen sinks, grids also come in a variety of sizes and shapes to complement them.
Caulk dries quicker than silicone. It's less tolerant to movement than silicone – should only be used in areas where there is little or no movement. Caulk is ideal for filling gaps in living areas like between skirting boards, picture rails and built-in furniture. You can paint over it with any paints or varnishes.
Caulk makes your surface airtight and watertight. Silicone sealants, on the other hand, remain flexible for years which make them ideal for areas that are prone to expansion and contraction. Silicone has strong binding properties that can be applied to almost any surface both indoors and outdoors.
