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. There are lots of different types of sealant available on the market, though, so between all the different kinds of caulk and sealants on the market, which one is best for your new sink installation? Whether you’ve installed countless sinks in your career or you’re working on an at-home DIY installation, it’s possible to have questions about what type of sink sealant is best to use.

While there are a lot of different factors to consider when choosing a sealant for your specific sink installation, silicone caulk is usually the best option for plumbing fixtures since it forms a waterproof seal and is easy to apply. Silicone caulk is also moisture and mildew resistant, meaning it will last longer and hold up against the elements for kitchen and bathroom applications. In this article, we’ll go a little further into detail about how to choose a sealant for your next sink installation, as well as discuss why silicone sealant is the best choice for most applications.

Factors To Consider When Choosing A Sealant For Sink Installation

If you’ve been to the hardware store or searched online for sealants, you’ve probably already realized that there are a lot of different types of caulks and sealants out there. While many of them explicitly say they cannot be used on sinks and other plumbing fixtures, some sealants boast that they’re a great option for sealing those things - so how do you choose the best type of sealant for your project? After all, using the wrong type of sealant is one of the most common sealant application mistakes.

Choosing the right sealant for a new sink installation is important to ensure that the sink is properly secured and sealed to prevent leaks and prevent water damage, but it isn’t always easy to make your decision. There are a few factors to consider when selecting a sealant.

Type of sink

The type of sink you are installing will influence the type of sealant you should use. For example, if you are installing a stainless steel sink, you can use silicone sealant or a plumber's putty. If you are installing a porcelain sink, you should use a non-silicone acrylic latex caulk. Silicone sealant is the best type of sealant to use for most types of sinks, as it is a highly versatile and durable material that will adhere to many surfaces.

Location of sink

The location of the sink will also affect the type of sealant you should use. If the sinks you’re sealing are located in a high-moisture area, such as a kitchen and bathroom, you should use a sealant that is mold and mildew resistant like Kitchen & Bath Mildew Resistant RTV Silicone Sealant. It’s usually a good idea to purchase silicone sealant for this project since it is not only mold and mildew resistant, but can form a strong watertight seal.

Personal preference

Ultimately, the type of sealant you choose may come down to personal preference. Some people prefer silicone because it is easy to work with, while others prefer plumber's putty because it is more durable. Most professionals and DIYers prefer working with silicone since it is easy to apply and will last a very long time.

Why Silicone Sealant Is The Best Choice For New Sink Installation

When trying to choose between types of caulk and sealant to use on your sink or other fixtures in kitchens and bathrooms, silicone sealant is an excellent choice. There are numerous benefits to silicone sealant that other caulks just cannot boast. For example, silicone sealant is capable of forming a fully watertight seal thanks to its strong adhesiveness, meaning you can not only rest assured that your appliances will be free of leaks but also that your silicone sealant will last for years to come.

Additionally, while silicone sealant is practical and highly useful, it is also extremely easy to apply and requires no professional experience or special training. All you’ll need to do is pick up a tube of silicone sealant, bring it home, and apply it using a caulking gun like the B1 Caulking Gun.
