Concrete Sealing Dos & Don'ts: 6 Expert Tips for Optimal Results

Concrete sealing is a critical process that ensures the longevity and durability of concrete surfaces. Whether you're sealing a garage, patio, or interior flooring, using the right sealant and following proper application techniques can protect your concrete from weathering, staining, and wear.

However, achieving the optimal result involves more than just applying a product. Essential steps must be followed and common mistakes avoided to ensure a high-quality, lasting seal.

Our expert guide will walk you through the key dos and don'ts of concrete sealing, providing expert tips on choosing the right sealant, preparation steps, application techniques, and more.

Read on to discover how you can ensure the best results with your concrete sealing project.

Choosing the Right Sealant: Factors to Consider

One of the most important steps in concrete sealing is selecting the right sealant for your specific application. Not all concrete sealants are created equal, and choosing the wrong one can result in reduced protection and a shorter lifespan for your concrete surface.

Factors to consider are:

Exposure to the Elements

For outdoor surfaces like driveways or patios, it's crucial to use a sealant to withstand the elements' exposure, especially in the Twin Cities area! Look for UV-resistant and waterproof options that protect against harsh weather like rain, snow, and extreme sunlight.

Sealants with lower VOCs (Volatile Organic Compounds) might be preferable for better air quality for indoor applications.

Traffic Levels

Traffic levels also play a role in choosing the right sealant. For areas with heavy foot or vehicle traffic, a durable, high-performance sealant is necessary to prevent wear and tear.

Aesthetic Considerations

When selecting the sealant, aesthetic factors, such as whether you want a matte or glossy finish, should be considered to get the perfect look. 

Preparation Steps for Concrete Sealing

Proper preparation is essential before sealing concrete, as this will ensure that the sealant adheres well and lasts long. Skipping these preparatory steps can lead to poor results and may require redoing the entire process sooner than expected, so we recommend:

Clean the Surface

Remove any dirt, debris, grease, or stains that could affect the sealant's bonding ability. Pressure washing is a great way to clean exterior concrete surfaces.

Do an Inspection

Repairing these before sealing is crucial, as sealants are not designed to fix structural issues. Use a concrete patch or filler to address cracks or holes, and allow these repairs to dry fully before proceeding.

Let the Concrete Fully Dry

Moisture trapped beneath a sealant can prevent proper adhesion, causing bubbling or peeling over time.

By thoroughly preparing your concrete, you'll set the stage for a successful sealing process and significantly improve the project's outcome.

Application Techniques for Effective Sealing

Effectively applying concrete sealant is a crucial part of the sealing process. The key to success is using the right tools and techniques.

First, choose the appropriate application tools, such as a high-quality roller or sprayer, depending on the sealant type. Rollers work well for smooth surfaces, while sprayers are often used for textured or vertical surfaces.

It is important to apply a thin, even coat of sealant. Start at one end of the surface and work your way across systematically to avoid missing spots or uneven layers.

Applying the sealant in thin layers will help prevent pooling or bubbles, which can create weak spots in the sealant. Avoid over-application, as this can lead to peeling or an overly glossy finish.

Make sure to follow the manufacturer’s instructions regarding drying time between coats.

Some sealants may require a second coat for optimal protection. By following these techniques, you’ll ensure a smooth, uniform seal that enhances both the look and durability of your concrete.

Common Mistakes to Avoid in Concrete Sealing

While sealing concrete may seem straightforward, several common mistakes can affect the project's outcome, so try to avoid:

Applying the Sealant in Less than Ideal Weather

Humidity, rain, and extreme temperatures can prevent the sealant from curing properly, leading to poor adhesion and reduced protection. It’s best to seal concrete when temperatures are between 50°F and 90°F and the surface is completely dry.

Not Prepping Thoroughly

Failing to clean the surface thoroughly or skipping crack repairs can cause the sealant to bond unevenly or not at all. Likewise, over-application is a common problem.

Too Much Sealant

Applying too much sealant can cause bubbles or a tacky surface, which can detract from the seal's appearance and durability.

Maintenance and Care After Sealing

Once your concrete surface is sealed, proper maintenance is crucial to extending its lifespan and keeping it looking great. Regular cleaning helps prevent dirt and debris from wearing down the sealant.

Use a mild detergent and water to clean the surface as needed, and avoid using harsh chemicals that can break down the sealant over time.

It's important to inspect the sealant regularly in areas with heavy traffic or harsh weather conditions. Over time, you may notice wear in high-traffic areas or places exposed to the elements.

If the sealant begins to show signs of degradation, consider resealing the concrete to maintain its protective layer.

Resealing your concrete every few years is a good practice for long-term durability. By keeping up with maintenance and resealing, you’ll ensure that your concrete surface remains protected and visually appealing.
