Understanding the Different Types of Concrete Sealers

When it comes to protecting and enhancing the lifespan of your concrete surfaces, choosing the right sealer is crucial. With a variety of options available, it’s important to understand the different types of concrete sealers and their unique benefits. From acrylic sealers to penetrating sealers, this guide will help you navigate the world of concrete sealers and make an informed decision for your project.

Penetrating Sealers

Penetrating sealers are a popular choice for protecting concrete surfaces due to their ability to penetrate the pores of the concrete, forming a chemical barrier that repels water and other liquids. There are several types of penetrating sealers, each with its own unique properties and benefits.

Silane/Siloxane Sealers

Silane/siloxane sealers are a common type of penetrating sealer that chemically reacts with the concrete to create a hydrophobic barrier. This barrier repels water and other liquids, preventing them from seeping into the concrete and causing damage. Silane/siloxane sealers are ideal for protecting concrete driveways, sidewalks, and other outdoor surfaces.

Silicate Sealers

Silicate sealers are another type of penetrating sealer that penetrates deeply into the concrete to form a chemical barrier that protects against water, oil, and other contaminants. Silicate sealers are often used on interior concrete surfaces, such as floors and countertops, to provide long-lasting protection against stains and wear.

Siliconate Sealers

Siliconate sealers are a popular choice for protecting concrete surfaces from water and salt damage. These sealers penetrate deeply into the concrete to form a durable barrier that repels water and other liquids. Siliconate sealers are commonly used on concrete driveways, patios, and other outdoor surfaces to protect against freeze-thaw damage and salt corrosion.

Topical Sealers

Topical sealers are applied directly to the surface of the concrete and form a protective layer that prevents moisture and other contaminants from penetrating the surface. There are three main types of topical sealers: acrylic sealers, urethane sealers, and epoxy sealers.

Acrylic Sealers

Acrylic sealers are one of the most popular choices for sealing concrete due to their ease of application and affordability. They provide a glossy finish and are available in both solvent-based and water-based formulas. Acrylic sealers are ideal for indoor surfaces or decorative concrete where a glossy finish is desired.

Urethane Sealers

Urethane sealers are known for their durability and resistance to abrasion, making them a great choice for high-traffic areas or industrial floors. They are available in both solvent-based and water-based formulas and provide a high-gloss finish. Urethane sealers are more expensive than acrylic sealers but offer superior protection against chemicals and UV rays.

Epoxy Sealers

Epoxy sealers are a two-part system that provides a thick, durable coating to the concrete surface. They are commonly used in commercial and industrial settings where a high level of protection is required. Epoxy sealers are resistant to chemicals, abrasion, and UV rays, making them ideal for garage floors, warehouses, and manufacturing facilities.

Overall, the type of concrete sealer you choose will depend on the specific needs of your project and the level of protection required. Consider factors such as durability, gloss level, and resistance to chemicals when selecting a sealer for your concrete surface.

Decorative Sealers

When it comes to enhancing the appearance of concrete surfaces, decorative sealers are the way to go. These sealers not only provide protection but also add a decorative touch to the concrete. There are several types of decorative sealers available, each serving a specific purpose.

Stamped Concrete Sealers

Stamped concrete sealers are designed to enhance the appearance of stamped concrete surfaces. They come in a variety of finishes, ranging from matte to high-gloss, and can help bring out the intricate patterns and textures of stamped concrete. These sealers also provide protection against stains, water damage, and UV rays, making them a popular choice for outdoor applications.

Colored Concrete Sealers

Colored concrete sealers are a great way to add a pop of color to your concrete surfaces. These sealers come in a wide range of colors, allowing you to customize the look of your concrete to suit your design preferences. In addition to adding color, colored sealers also provide protection against wear and tear, making them a versatile choice for both indoor and outdoor applications.

Glossy Sealers

Glossy sealers are perfect for achieving a sleek and polished look on concrete surfaces. These sealers create a glossy finish that enhances the natural beauty of the concrete while providing protection against stains, scratches, and UV damage. Glossy sealers are commonly used on countertops, floors, and other high-traffic areas where a durable and aesthetically pleasing finish is desired.

In conclusion, decorative sealers offer a versatile and practical solution for enhancing the appearance and durability of concrete surfaces. Whether you’re looking to add color, texture, or shine to your concrete, there is a decorative sealer available to meet your needs.


In conclusion, understanding the different types of concrete sealers is essential for anyone looking to protect and enhance their concrete surfaces. Whether you are looking to seal a driveway, patio, or other concrete structure, selecting the right sealer can make a significant difference in terms of durability, appearance, and long-term maintenance. By considering factors such as the type of concrete, level of protection needed, and desired finish, you can make an informed decision on which sealer will best suit your specific needs. Remember to always follow the manufacturer’s instructions for application and maintenance to ensure the best results. With the right sealer, you can enjoy a beautiful and long-lasting concrete surface for years to come.
