If you’ve recently installed new concrete, you might be considering when to apply concrete sealer. Is it better to seal it right away, or should you wait?

Applying concrete sealer to new concrete is a crucial step in preserving its look and extending its life. In this article, we’ll explore the optimal timing for sealing new concrete with a concrete sealer and explain why this process is important for maintaining your concrete’s appearance and durability.

Why Is Sealing New Concrete Important?

Before we dive into the best time to seal new concrete, let’s first understand why sealing is important.

Protection Against Stains and Damage

Concrete is a porous substance, allowing it to easily absorb liquids and become stained. By sealing new concrete, you form a protective layer that stops liquids from seeping into the surface and staining it. This sealant also shields the concrete from extreme weather conditions, including the effects of freeze-thaw cycles.

Enhances Appearance

Sealing new concrete can also enhance its appearance. Sealing concrete can enhance its natural color and texture, providing a more refined and complete appearance. Additionally, it can deliver either a glossy or matte finish, based on the specific sealer applied.

Increases Durability

Sealing new concrete can also increase its durability. Sealing helps protect against cracking, spalling, and other types of damage that may develop with time. This is especially important for high-traffic areas, such as driveways and walkways.

When Is the Best Time to Seal New Concrete?

Now that the significance of sealing new concrete is clear, let’s explore the optimal timing for this process.

Wait for the Concrete to Cure

The most important factor to consider when deciding when to seal new concrete is the curing time. Concrete takes time to fully cure and reach its maximum strength. The duration of the curing process can differ based on variables like temperature, humidity, and the specific concrete mix utilized. In general, it’s recommended to wait at least 28 days before sealing new concrete. This allows enough time for the concrete to cure and reach its full strength. Sealing too early can result in a weaker and less durable surface.

Check for Moisture

Before sealing new concrete, it’s important to check for moisture. Sealing over a damp or wet surface can result in a cloudy or hazy appearance, and can also cause the sealer to peel or flake off.

To test for moisture, affix a plastic sheet onto the concrete surface and let it sit for 24 hours. Should condensation form on the plastic’s underside, the concrete remains too damp for sealing. Ensure the surface is fully dry before moving ahead with the sealing process.

Consider the Weather

Consider the Weather Image

The weather can also play a role in determining the best time to seal new concrete. It’s best to seal on a day with mild temperatures (between 50-80 degrees Fahrenheit) and low humidity. Avoid sealing on days with high winds or rain in the forecast, as this can affect the application and drying process.

How to Seal New Concrete

Now that you know the best time to seal new concrete, let’s discuss the steps involved in the sealing process.

Clean the Surface

Prior to sealing, thoroughly cleaning the concrete surface is crucial. This guarantees that the sealer bonds well and offers optimal protection. Use a pressure washer or a stiff-bristled brush to clear away all dirt, debris, and stains from the surface.

Repair Any Cracks or Damage

Before sealing, it’s crucial to address any cracks or damage on the concrete surface. Fill cracks or holes using a concrete patching compound and wait for it to dry completely before moving on.

Apply the Sealer

When applying the sealer, it’s important to follow the manufacturer’s instructions carefully. Apply a uniform layer of sealer to the concrete surface using a roller or sprayer, focusing on small sections at a time to prevent overlapping.

Allow the Sealer to Dry

Once the sealer is applied, let it dry fully before you walk or drive on the surface. This can take anywhere from 24-48 hours, depending on the type of sealer used and the weather conditions.

Types of Concrete Sealers

Numerous varieties of concrete sealers exist, each offering distinct characteristics and advantages. Below are some of the most prevalent
types of concrete sealers:

Acrylic Sealers

Acrylic sealers are a favored option for new concrete due to their ease of application, quick drying time, and ability to deliver either a glossy or matte finish. They also offer good protection against stains and UV rays.

Penetrating Sealers

Penetrating sealers work by sinking into the concrete’s pores, forming an internal protective barrier. They are a good choice for outdoor surfaces, as they provide excellent protection against water and salt damage.

Epoxy Sealers

Epoxy sealers offer a robust solution for new concrete, providing resistance to chemicals, stains, and abrasions. This makes them a preferred choice for garage floors and other areas that experience heavy traffic.
