With an abundance of different caulks and sealants on the market, it’s not uncommon to feel overwhelmed when choosing the right product for your next bathroom or kitchen project. Understanding what separates caulks from sealants is a great place to start.
You’ve probably noticed that “caulk” and “sealant” are often used interchangeably. That’s because both serve a similar purpose: acting as sealing agents to fill gaps and cracks and bonding agents between building materials, such as joining countertops to sink bases.
They are also both applied to surfaces to prevent leaks and used with or without a caulking gun, which is why sealant is technically categorized as a type of caulk.
What’s the Difference Between Caulk and Sealant?
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. The silicone material allows a sealant to expand easily and contract during changing temperatures without losing its airtight/watertight seal.
Therefore, sealants are a smart choice for areas that experience frequent weather fluctuation and high moisture levels, like kitchens, bathrooms, and around doors and windows.
NOID 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 sealants to ensure you find the best fit for various indoor and outdoor projects.
What are the Types of Caulk and Sealants?
Noid makes various professional-grade caulks and sealants for residential or commercial use. Used on a variety of surfaces and applications, Noid offers caulks and sealants in silicone, latex, and acrylic formulas.

Characteristics
-
Environmentally Friendly & Safe: No organic solvents used, making it safe and eco-friendly.
-
High Adhesive Strength: Can directly fix objects with strong bonding power.
-
Wide Temperature Range: Usable from -40°C to 90°C for long-term performance.
-

Application
SS404 is designed for bonding various lightweight materials and objects such as glass, plastic, porcelain, wood, aluminum-plastic board, fireproof board, etc. It is a new generation of environmentally friendly liquid nails.
Application Tips
-
Ensure the bonding surface is dry, clean, firm, and free of floating sand.
-
Apply dot or line coating and press the adhesive firmly during bonding to achieve an even, thin layer.
-
Bond the surfaces before the adhesive forms a skin. The skinning time shortens at higher temperatures, so apply as soon as possible after coating.
-
Optimal usage temperature: 15
40°C. For winter, warm the adhesive at 4050°C before use. In hot weather, the adhesive may become thinner, and initial adhesion may decrease—increase adhesive amount if necessary.

4. Polyurethane Sealant
Polyurethane sealant is multi-purpose and extremely durable. It is an excellent lead substitute for caulking cast iron soil pipe joints (Oakum must be used for this application). This single-component sealant cures rapidly to a firm yet flexible, waterproof and weather-resistant seal.
As a multi-purpose repair product, it can also be used for caulking the perimeters of frame openings, ductwork, wood, or masonry expansion joints and for glazing both inside and out. It also has many uses in the home, construction, automotive, RV, and marine environments.
Common plumbing applications for polyurethane caulk/sealant include:
● Sealing soil pipes and ductwork.
● Repairing and caulking interior and exterior perimeters of frame openings and expansion joints and for glazing.
● Useful in building construction, automotive, RV, and marine applications.
● Adheres to cast iron, masonry, wood, concrete, stone, metals, plastic, glass, aluminum, tile, vitreous china, and porcelain.
