Silicone and silicone-blend caulks are most commonly used for kitchen and bath caulk projects. They are the best kind of caulk for showers, bathtubs and sinks.
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.
The main difference between plumbers putty or silicone for sink drain is how easy the substances are to manipulate or remove. Plumbers putty is very easy to manipulate into tight areas, and it's also easier to remove. That makes silicone putty better for waterproofing, even if it's more difficult to work with.
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.
In the bathroom, you need silicone sealant. Acetoxy silicone sealants are some of the best products for joints around bathtubs, showers, sinks and bathroom counters, because they adhere very well to enamel, stoneware, glass and tiles.

Longevity & Durability
Plumber's putty can last on average for 15 years once applied due to the flexible material. On the other hand, silicone putty lasts about 10 years because it is harder than the former, so it either breaks or wears down faster.
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. Using a high quality, waterproof sealant prevents water and debris from entering the gaps.
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.
It's easy to understand why silicone sealants are so popular – whether you're a professional plumber or a homeowner looking to carry out some quick repairs with long-lasting results, silicone sealant is the answer. This powerful liquid adhesive is useful not just for repairs, but also for preventing future problems.
If you're installing a new sink, you'll need to apply sealant in order to ensure that your sink does not leak or fall subject to moisture damage.
Silicone caulk is basically the same thing as plumbers putty, but it's designed to be used in a much wider variety of applications. This type of caulking is typically clear and flexible, meaning that you can easily see through it to check whether it's properly sealed.
Because of this, you do need something in addition to the bead of adhesive or sealant around the rim of the sink to support that weight. Silicone on its own definitely has holding power, but it must not be the only thing doing the work.
It's not recommended to expose the silicone to moisture before the caulk cures completely to ensure the caulk is completely waterproof. However, if you can't wait 24 hours, you should at least wait 12 hours.
Most silicone sealant products will last a minimum of 20 years, but you may want to begin checking your windows and in your bathroom sooner to ensure there are no gaps anywhere. When checking the silicone sealants around your home, first look at the condition of the silicone product.
When it comes to fixing leaks, silicone caulk is one of the best options because it's inexpensive, easy to use, and can be found in most hardware stores.
Can you use too much plumbers putty? It is normal to use an excessive amount of plumbers putty because as you tighten the parts together the excess putty will squeeze out. You can then reclaim the squeeze-out and use it again.
How Long Does Plumber's Putty Take to Set? It takes a few hours for plumber's putty to set. You can use a drain or tap immediately after installing the putty, although waiting a few hours may yield the best results. The putty will expand so might create a tighter seal.
Even when you're sure a project calls for plumber's putty, there are instances where it shouldn't be used. Putty should remain malleable throughout its life. To use it, plumbers roll the putty between our fingers to shape it. If you begin rolling the putty and it flakes or cracks, toss it out.
Acrylic Latex Caulk *Plus Silicone - In my opinion this is the minimum standard of sealant that should be used for interior painting project applications such as the joints where baseboards, door & window casings, and crown moldings meet the walls.
In general, sealant is the prefered sealing solution for bathtubs and showers, as it is more water resistant than traditional caulk. Silicone sealant forms a watertight seal that is resistant to heavy temperature changes.
The key distinction between caulk and sealant? Elasticity. Caulk is typically made from a mixture of latex and acrylic materials, which make it more rigid and prone to shrinking when cured. A sealant offers superior elasticity and water resistance because it primarily contains silicone.
