7 Common Mistakes in Sealing Concrete

Concrete is a popular material used for constructing driveways and pool decks. However, concrete is a porous material that absorbs water and other liquids easily. Therefore, sealing concrete is an essential process that helps to protect it from damage caused by weather, wear and tear, and chemicals. However, sealing concrete requires proper preparation, knowledge, and skills to avoid costly mistakes that can lead to an inferior result. In this blog post, we will discuss the most common mistakes homeowners make when trying to seal concrete driveways and pool decks themselves.

#1 Lack of Proper Cleaning

    Before sealing concrete, it’s essential to ensure that it’s clean and free from any dirt, debris, or stains. Unfortunately, many homeowners neglect this crucial step, leading to poor adhesion and an unsightly finish. To clean concrete properly, start by sweeping the surface to remove any loose debris. Next, use a pressure washer to remove any dirt, grime, or stains. If there are any stubborn stains, use a concrete cleaner and a scrub brush to remove them. Allow the concrete to dry completely before sealing it.

    #2 Choosing the Wrong Sealer

    Choosing the right sealer is crucial to achieving a long-lasting and attractive finish. However, many homeowners make the mistake of selecting the wrong sealer for their concrete surface. For instance, some sealers are better suited for driveways, while others are more appropriate for pool decks. It’s essential to consider the type of concrete surface you’re sealing, the level of foot or vehicle traffic, and the climate in your area before selecting a sealer.

    #3 Applying the Sealer Too Thickly

    Applying the sealer too thickly can lead to an uneven finish, bubbling, and cracking. It’s crucial to follow the manufacturer’s instructions and apply the sealer thinly and evenly. You can apply the sealer using a sprayer, a roller, or a brush, depending on the surface and the sealer’s viscosity. Remember to apply the sealer in a consistent pattern, and avoid overlapping areas as this can cause the sealer to pool in some areas.

    #4 Applying the Sealer in the Wrong Weather Conditions

    Applying the sealer in the wrong weather conditions can affect the sealer’s performance and durability. It’s crucial to apply the sealer when the temperature is between 50°F and 90°F and when there’s no rain in the forecast for at least 24 hours. Applying the sealer in high humidity or extreme temperatures can lead to a cloudy finish or bubbling.

    #5 Not Allowing the Sealer to Dry Properly

    Allowing the sealer to dry completely is essential to achieving a long-lasting and durable finish. However, many homeowners make the mistake of not allowing the sealer to dry properly, leading to a tacky or sticky finish. It’s essential to follow the manufacturer’s instructions and allow the sealer to dry for at least 24 to 48 hours, depending on the sealer and the weather conditions.

    #6 Neglecting Maintenance

    Sealing concrete is not a one-time process. It requires regular maintenance to ensure that it continues to protect the surface from damage. Unfortunately, many homeowners neglect maintenance, leading to premature wear and tear and the need for resealing sooner than expected. To maintain the sealer, avoid using harsh chemicals, abrasive cleaners, or pressure washers on the surface. Instead, sweep the surface regularly, and clean any spills or stains promptly.

    #7 Not Seeking Professional Help When Needed

    Sealing concrete is a task that requires proper knowledge, skills, and tools. While it’s possible to seal concrete yourself, it’s crucial to seek professional help when needed. For instance, if you’re dealing with a large surface area or if you’re unsure about the type of sealer to use.
