As a homeowner, you take pride in your outdoor space, and a concrete patio is a great way to extend your living area and create a comfortable spot to relax and entertain. However, concrete patios require regular maintenance to keep them looking their best. One of the most important steps in maintaining your patio is sealing it to protect it from the elements and extend its lifespan. But with so many sealers on the market, it can be overwhelming to choose the right one for your patio. In this article, we’ll delve into the world of concrete patio sealers and explore what’s best to seal your concrete patio.
Why Seal Your Concrete Patio?
Before we dive into the different types of sealers, it’s essential to understand why sealing your concrete patio is so important. Here are a few reasons why:
- Protection from the Elements: Concrete is a porous material that can absorb water, dirt, and other substances, which can lead to staining, cracking, and erosion. Sealing your patio protects it from these elements, ensuring it remains safe and stable for years to come.
- Easy Maintenance: Sealing your patio makes it easier to clean and maintain. A sealed patio is more resistant to stains, and cleaning up spills and messes is a breeze.
- Enhanced Appearance: Sealing your patio can also enhance its appearance. By protecting the concrete from fading and discoloration, your patio will look like new for longer.

4. Desired Sheen
Sealers come in a range of sheens, from matte to high-gloss. Consider the desired appearance of your patio when choosing a sealer.
5. Budget
Sealers vary in price, so it’s essential to set a budget before making a decision. Consider the cost per square foot and the coverage rate when choosing a sealer.
Application and Maintenance
Once you’ve chosen the right sealer for your patio, it’s essential to apply it correctly and maintain it regularly. Here are some tips to keep in mind:
1. Preparation is Key
Before applying a sealer, make sure your patio is clean and free of dirt, oil, and other substances. Power wash the patio to remove any dirt or debris, and let it dry completely before applying the sealer.

What is concrete sealing, and why is it necessary?
Concrete sealing is the process of applying a protective layer to your concrete patio to shield it from various environmental elements, stains, and wear and tear. It’s necessary because concrete is a porous material that can absorb water, dirt, and other substances, leading to damage, discoloration, and structural issues over time. Sealing your concrete patio helps to prevent these problems, ensuring it remains durable, attractive, and low-maintenance.
Proper sealing also makes cleaning easier, as it prevents dirt and stains from penetrating the concrete. Additionally, sealing can enhance the appearance of your patio by bringing out the natural colors and textures of the concrete. It’s an essential step in maintaining the longevity and beauty of your outdoor space.
What are the different types of concrete sealers available?
There are two primary categories of concrete sealers: topical and penetrating. Topical sealers, also known as coatings or surface sealers, form a protective barrier on the surface of the concrete. They can be either solvent-based or water-based and are often applied in a thin layer. Topical sealers are easy to apply and provide a high-gloss finish, but they may not last as long as penetrating sealers.
Penetrating sealers, on the other hand, absorb into the concrete to protect it from within. They can be either silane- or siloxane-based and provide long-term protection against water, salt, and stains. Penetrating sealers are often used on high-traffic areas or in regions with extreme weather conditions. It’s essential to choose the right type of sealer for your specific needs and preferences.
How do I prepare my concrete patio for sealing?
Before sealing your concrete patio, it’s crucial to ensure it’s clean and free of dirt, oil, grease, and other substances that may interfere with the sealing process. Start by sweeping the patio to remove any debris, followed by a thorough power washing to remove dirt and grime. If you notice any stains, use a concrete cleaner or stain remover to eliminate them.
Once your patio is clean, allow it to dry completely before applying the sealer. It’s also essential to repair any cracks or damage to the concrete before sealing. This may involve filling cracks with a concrete patching compound or replacing damaged sections of the patio. Proper preparation will ensure a successful sealing process and a long-lasting finish.
How do I apply a concrete sealer?
The application process for concrete sealers varies depending on the type of sealer you’re using. For topical sealers, apply a thin layer using a roller or sprayer, working in sections to maintain even coverage. For penetrating sealers, apply the product to the concrete using a sprayer or roller, following the manufacturer’s instructions. Be sure to work in small sections, as penetrating sealers can take time to absorb into the concrete.
Regardless of the type of sealer, it’s essential to follow the manufacturer’s instructions and take necessary safety precautions, such as wearing protective gloves and eyewear. Apply the sealer in thin, even layers, allowing each layer to dry before applying the next. This will help prevent pooling or uneven coverage.
How long does a concrete sealer last?
The lifespan of a concrete sealer depends on various factors, including the type of sealer, environmental conditions, and maintenance. Topical sealers typically last between one to three years, while penetrating sealers can last up to 10 years or more.
Regular maintenance, such as cleaning and resealing as needed, can help extend the life of your sealer. Exposure to harsh weather conditions, heavy foot traffic, or extreme temperatures can reduce the lifespan of the sealer. Be sure to follow the manufacturer’s recommendations for reapplication and maintenance to ensure the best results.
Can I seal a new concrete patio, or should I wait?
It’s generally recommended to wait at least 28 days before sealing a new concrete patio. This allows the concrete to fully cure and harden, ensuring the sealer adheres properly and lasts longer.
However, some manufacturers may recommend sealing new concrete sooner, as long as it’s been properly cured and dried. Always follow the manufacturer’s instructions and consult with a professional if you’re unsure about the best time to seal your new patio.
Should I hire a professional to seal my concrete patio?
While it’s possible to seal your concrete patio yourself, hiring a professional can ensure a high-quality finish and long-lasting results. A professional will have the necessary experience and equipment to properly prepare the patio, apply the sealer, and ensure even coverage.
Additionally, a professional can help you choose the right type of sealer for your specific needs and provide guidance on maintenance and future reapplication. If you’re short on time or not comfortable with the process, hiring a professional is a worthwhile investment for your outdoor space.
