Does polished concrete have to be sealed?

Polished concrete is a popular choice for many commercial and residential spaces due to its sleek, modern appearance and durability. But one of the most common questions asked is: does polished concrete need to be sealed? The short answer is yes, in most cases, sealing is recommended to enhance the longevity and performance of the floor. Here's why.

Protecting Your Investment

Why Sealing Polished Concrete Matters

While polished concrete floors are naturally durable and resistant to wear, they are still porous. This means they can absorb liquids, oils, and other substances if left unsealed. Sealing polished concrete provides an added layer of protection, preventing stains, moisture intrusion, and even damage from heavy foot traffic.

Prolonging Floor Life

Sealing helps reduce surface wear over time, especially in high-traffic areas. By adding a sealer, you help preserve the smooth finish of the concrete, ensuring that it maintains its appearance and strength for years to come. Unsealed concrete may show signs of wear faster and could require more frequent maintenance.

Enhancing the Look of Polished Concrete

Boosting Shine and Aesthetic Appeal

Sealers not only protect your polished concrete but can also enhance its appearance. With the right sealer, you can boost the natural shine of the floor, giving it a more polished and high-gloss finish. This added luster can be especially important in spaces where aesthetics play a key role, such as retail environments or modern office spaces.

Color and Stain Enhancement

For those who have added stains or dyes to their polished concrete, a sealer can intensify the color, giving it more depth and vibrancy. Without sealing, the color may appear dull or uneven over time, especially in areas exposed to sunlight or moisture. A quality sealer can help maintain and protect that custom look.

What Happens If You Don’t Seal Polished Concrete?

Increased Risk of Stains and Damage

If polished concrete is left unsealed, its porous surface can absorb spills, leading to permanent staining. Over time, dirt and debris can accumulate in these pores, making the floor harder to clean and maintain. In areas like kitchens, warehouses, or garages, exposure to oils, chemicals, or water can also damage the floor without the protective layer a sealer provides.

Reduced Longevity

While polished concrete is strong, it’s not invincible. Without a sealer, the surface can become more susceptible to scratches, etching, and wear, particularly in areas with heavy machinery, foot traffic, or abrasive materials. Regular sealing ensures that the floor remains durable and maintains its polished look for longer periods.

How Often Should Polished Concrete Be Sealed?

Initial Sealing After Installation

When polished concrete is first installed, sealing is a crucial step to lock in the finish and protect the surface from immediate damage. It is recommended that you work with professionals like C&N Decorative Concrete to apply the right type of sealer based on the floor’s usage and environment.

Maintenance Sealing

Sealed polished concrete floors don’t need to be resealed often, but periodic maintenance is still necessary. Depending on the traffic and exposure to elements, resealing every 2-5 years can keep the floor in top condition. C&N Decorative Concrete offers professional sealing and resealing services to ensure that your polished concrete stays beautiful and functional over time.

Choosing the Right Sealer

Not all sealers are created equal. Different environments require different types of sealers, and factors like foot traffic, UV exposure, and the use of chemicals can impact the choice. C&N Decorative Concrete specializes in selecting the perfect sealer for your polished concrete, ensuring it meets your specific needs and aesthetic goals.
