Why Seal Your Concrete 

Have you ever wondered why concrete surfaces need to be sealed? Concrete sealing is crucial for a variety of reasons. By providing a protective layer, it safeguards your concrete from damage induced by water, grease, oil stains, de-icing salts, and harsh UV rays. In addition, it enhances the appearance of decorative concrete by enriching the color and adding sheen. 

Reliable sealing also elongates the lifespan of your concrete. Sealed surfaces resist wear and tear and are easier to clean, making them a practical and cost-efficient choice for homeowners. Your concrete will not only look fantastic, but you will save on future repair costs. 

In short, concrete sealing is a protective measure that grants longevity and maintains the aesthetic appeal of your surface. It's a small investment with a significant return in the long term. 

Types of Concrete Sealers 

Now that we understand the relevance of concrete sealing, we must delve into the types of sealers available. There are primarily two types: film-forming sealers and penetrating sealers. 

Film-forming sealers form a protective layer on the surface of the concrete enhancing its color and giving it a glossy finish. These are ideal for decorative concrete. Conversely, penetrating sealers sink into the concrete, offering solid protection against moisture and de-icer salts. They are best suited for exterior concrete like driveways and sidewalks, due to their great durability. 

Each type has its strengths and drawbacks, which can influence the choice of sealer. It’s imperative to understand these pros and cons to select the best sealer for your concrete. 

Preparing The Concrete for Sealing 

Preparation is an important preliminary step in concrete sealing. It is critical to achieve a clean and dry surface before starting the sealing process. 

The concrete has to be thoroughly cleaned of all dust, grease, or oil stains. This could involve scrubbing, pressure washing, or etching depending on the severity of the dirt and stains. A failure to do so could prevent the sealer from adhering well to the surface. 

The next step is to ensure the concrete is fully dry. Applying sealer to damp concrete may result in a murky and patchy appearance, damaging the visual appeal. 

The preparation phase is, therefore, an essential pre-requisite to the sealing process, ensuring a successful and visually pleasing result. 

Application Techniques 

The application technique can significantly influence the final appearance and durability of your sealed concrete surface. From spraying to rolling, the correct method depends on the type of sealer and the size of the area to be sealed. 

Spraying is often used for larger areas, providing an even coat of sealer. It is faster than other methods but requires skill to avoid over-spray or uneven application. 

Rolling is another common method suitable for both indoor and outdoor use. It can reach corners and edges that a sprayer might miss and gives more control over the amount of sealer applied. 

Whichever method you choose, the goal is to achieve an even, thick seal that provides maximum protection and renders your concrete surface more vibrant and durable. 

Sealing Frequency and Maintenance 

Even with a high-quality sealer and correct application, maintenance is crucial for a long-lasting concrete surface. The frequency of resealing primarily depends on the level of traffic and weather conditions the surface is exposed to. 

Typically, outdoor concrete surfaces might require resealing every two years while interior ones can generally last more than two years. Timely maintenance will prevent premature aging and keep your concrete surfaces in top shape. 

Conclusion 

Concrete sealing is more than just a cosmetic measure. It is a strategic approach that ensures the durability, longevity, and visual appeal of your concrete surfaces. By understanding the why and how of sealing, you can make informed decisions about the type of sealer to use, how to prepare and maintain your surfaces, and what application method best suits your needs. 

Sealed concrete surfaces are not just about looks; they are about sustainability and practicality. The effort you invest into protecting your concrete will pay dividends in the form of a beautiful, long-lasting, and trouble-free surface. Don't let the elements take their toll on your concrete; take charge of its future through effective sealing.
