The right bathroom caulk or sealant can make all the difference in making your bathroom watertight. From preventing water migration to stopping mold growth, choosing the best sealant can protect your bathroom for years.
With an abundance of waterproof bathroom caulks and common types of sealants on the market, it’s not uncommon to feel overwhelmed when choosing the right product for your next bathroom project. Understanding what separates bathroom caulk vs sealant is a great place to start.
However, the primary goal in bathrooms remains to keep moisture at bay.
Oatey Tip: The two most important factors to keep in mind when selecting a caulk or sealant are the application site’s temperature range and moisture level.
Let’s explore the unique properties and benefits of some of the most common caulks and bathroom sealants to ensure you find the best fit for your project.
Acrylic-latex caulk, also known as latex or general-purpose caulk, is water-based and provides excellent adhesion for bathroom materials such as tile. Unlike a silicone sealant, it is paintable once cured, produces fewer fumes, and can be cleaned with mild soap and water rather than a chemical solvent. This caulk type is also easier to apply and is ideal for hard-to-reach and time-sensitive applications.
Typical bathroom applications for regular and specialty acrylic-latex caulk include:
If you’re looking to combine the strong sealing properties of a silicone sealant and the ease of application and cleanup that an acrylic-latex bathroom caulk offers, opt for a siliconized acrylic-latex caulk.

It is also made to dry quickly (only 24 hours) and glides smoothly on surfaces for frustration-free shaping and blending.
