The Dos and Don’ts of Sealing New Concrete Sidewalks

When it comes to sealing new concrete sidewalks, following the right steps is crucial to ensure longevity and durability. By understanding the dos and don’ts of this process, you can protect your investment and maintain the appearance of your sidewalk for years to come. In this article, we will discuss the key dos and don’ts that you should keep in mind when sealing new concrete sidewalks.

Dos of Sealing New Concrete Sidewalks

Clean the surface thoroughly

Before applying a concrete sealer, it is important to clean the surface of the sidewalk thoroughly. This includes removing any dirt, debris, oil stains, or other contaminants that may prevent the sealer from properly adhering to the concrete. Use a pressure washer or a concrete cleaner to ensure the surface is clean and free of any impurities.

Allow the concrete to cure completely

It is crucial to allow the newly poured concrete sidewalk to cure completely before applying a sealer. Typically, concrete should be allowed to cure for at least 28 days before sealing. This will ensure that the concrete is fully hardened and ready to be sealed, leading to a stronger and more durable sidewalk in the long run.

Apply a high-quality concrete sealer

When sealing a new concrete sidewalk, it is important to use a high-quality concrete sealer. Look for sealers that are specifically designed for exterior concrete surfaces and provide protection against water, UV rays, and other elements. Be sure to follow the manufacturer’s instructions for application, and apply the sealer evenly to ensure maximum protection and longevity for your sidewalk.

Don’ts of Sealing New Concrete Sidewalks

When it comes to sealing new concrete sidewalks, there are certain mistakes that should be avoided in order to ensure the best results. Here are some important "don’ts" to keep in mind:

Don’t seal too soon

One common mistake that people make when sealing new concrete sidewalks is applying the sealer too soon. It’s important to allow the concrete to cure properly before applying any sealant. Typically, it’s recommended to wait at least 28 days before sealing new concrete to ensure that it has had enough time to fully cure.

Don’t apply a sealer in extreme weather conditions

Another mistake to avoid is applying a sealer in extreme weather conditions. Sealing new concrete sidewalks in very hot or cold temperatures can lead to poor adhesion and a less effective seal. It’s best to apply the sealer when the weather is mild and dry to ensure the best results.

Don’t apply too thick of a coat

Applying too thick of a coat of sealer is another common mistake that can lead to issues with the finished result. A thick coat of sealer can lead to bubbling, peeling, and an uneven finish. It’s important to follow the manufacturer’s instructions regarding the recommended thickness of the sealer coat to achieve the best results.

By avoiding these common mistakes when sealing new concrete sidewalks, you can ensure that your sidewalk is properly protected and looks great for years to come.
