Concrete sealing is the process of applying a protective coating to concrete surfaces in order to shield them from damage over time. As one of the most widely used construction materials, concrete is very durable but still vulnerable to deterioration without the proper safeguards from weathering, chemicals, and other environmental factors. For more on this, read our post on why concrete cracks. 

Using the right concrete sealer creates a defensive barrier that prevents water, salt, and other contaminants from penetrating the concrete and breaking it down. Given the variations in concrete materials and conditions they are exposed to, not all surfaces can be effectively sealed with the same products. Driveways, parking lots, patios, floors, and countertops all require sealers formulated for their specific uses and needs. Today, we will discuss the sealing process and share our top sealer recommendations for each application.

Best Sealers for Concrete

For Parking or Walking Areas: PENTREAT 244-20 W/B

Concrete driveways and parking lots require a premium-grade sealer that protects from fuels, oils, and weathering. For these surfaces we recommend PENTREAT 244-20 W/B. This professional water-based silane penetrating sealer safeguards your concrete surface against all the usual conditions, but it’s also specialized to protect against thaw damage from precipitation and ice melt chemicals. Beyond all that, it’s easy to apply, too!

For Parking or Walking Areas: INTRAGUARD

To protect freshly poured concrete surfaces of all kinds from initial exposure, use INTRAGUARD. As a penetrating sealer, one coat offers full coverage of your bare concrete surface. This breathable formula ensures there’s no damage during the delicate curing period and prevents moisture from seeping inside. This leads to a much more durable and long-lasting surface!

For Parking or Walking Areas: DECK-O-SHIELD

Use DECK-O-SHIELD Sealer on freshly poured slabs within 28 days of the pour. Its wet-look shine enhances beauty without obscuring natural tones. Of course, the sealer also acts as a more than sufficient protector. Its breathability ensures there is no bubbling or peeling even if applied during the concrete curing process.

For Stamped Concrete: EXPO-GLOSS

To maintain the visual appeal of freshly stamped concrete for as long as possible, it is necessary to use a sealer. Freshly stamped concrete must be safeguarded with a sealer allowing the vivid details to shine through. For this application, we suggest EXPO-GLOSS Sealer. Its breathable formula does not change the color or texture of stamped designs but still offers plenty of protection. It shields against water and salt penetration to preserve the beauty of stamping patterns outside.

This high-performance patio sealer withstands foot traffic and all weather conditions without the need for frequent reapplication.

For Floors: CS-309-25

Floor finishes like garage epoxies require sealing to uphold the look, durability, and longevity. CS-309-25 protects floors from oils, antifreeze, and other automotive fluids penetration. This epoxy-based sealer is designed to provide a strong and long-lasting finish for garage floors. It is resistant to stains, scratches, and hot tire pickup. This non-toxic, color-enhancing formula is also easy to apply yourself since it’s low-odor and fast-drying.


For surfaces like basements that require full demanding ultimate waterproofing, try EXPO-GLOSS OTC. Siloxane-based chemistry reactive work deep within the concrete to completely seal pores. Whether applied to a positive or negative side water pressure, it’ll form an elastic barrier that blocks water from penetrating the concrete surfaces.

why use a sealer 

Why Use a Sealer?

There are several reasons why you should consider sealing your concrete surfaces:

  • Increased Durability: Sealing helps to protect your concrete from the elements, including rain, snow, and UV rays. This can significantly extend the lifespan of your concrete surfaces and reduce the need for costly repairs.
  • Stain Resistance: Sealing creates a barrier that helps to prevent stains from penetrating the concrete. This is especially important for areas that are prone to spills, such as patios, driveways, parking lots, and floors.
  • Easier Maintenance: Sealed concrete is easier to clean and maintain than unsealed concrete. This is because the sealant helps to prevent dirt and grime from adhering to the surface.
  • Enhanced Appearance: Sealing can enhance the appearance of your concrete surfaces by making them look richer and more vibrant.

Choosing the Right Sealer

Not all concrete sealers are created equal. The type of sealer you choose will depend on several factors, including the type of concrete surface you are sealing, the desired level of protection, and your budget. Here are some of the most common types of concrete sealers:

  • Penetrating Sealers: These sealers penetrate the surface of the concrete and create a barrier that helps to prevent water and stains from penetrating the concrete. Penetrating sealers are typically invisible and do not change the appearance of the concrete.
  • Film-Forming Sealers: These sealers create a thin film on the surface of the concrete. Film-forming sealers are available in a variety of finishes, including matte, satin, and gloss.
  • Topical Sealers: These sealers are similar to film-forming sealers, but they are thicker and more durable. Topical sealers are often used on high-traffic areas, such as driveways and patios.

Proper concrete sealing preserve your property investment and curb appeal.

Sealing your concrete surfaces is a great way to protect your investment and extend the lifespan of your concrete. By choosing the right sealer and following the manufacturer’s instructions, you can ensure that your concrete surfaces look their best for years to come.

Periodic reapplication further braces surfaces through decades of demanding climate cycles and high-use areas. With professional-grade products tailored for your specific concrete type, protective coatings can extend the functional lifespan of your surface many times over.
