Is It Good To Seal Commercial Concrete?

When it comes to maintaining the durability and appearance of concrete surfaces in commercial settings, sealing is often a topic of considerable discussion. Given the investment involved in commercial concrete applications, it’s crucial to understand whether sealing is just an added expense or a beneficial practice. This article provides a deep dive into the importance of concrete sealing, especially in a commercial context.

Why Sealing Concrete is Beneficial

Sealing commercial concrete offers multiple benefits that are particularly significant in high-traffic areas. The primary advantages include:

  • Protection Against Stains: Commercial areas are prone to spills from oils, chemicals, and other substances that can stain and damage concrete. A high-quality sealer provides a protective layer that makes it easier to clean spills before they soak in, preserving the appearance of the concrete.
  • Enhanced Durability: Concrete sealers help protect against wear, abrasion, and weather conditions, extending the life of the concrete. This is especially important in climates where freeze-thaw cycles can cause unsealed concrete to crack and deteriorate more quickly.
  • Improved Aesthetics: Sealers can enhance the natural color of concrete and give it a gloss or matte finish, depending on the type of sealer used. This can be particularly appealing in commercial settings where appearance matters.
  • Moisture Prevention: Sealing blocks the penetration of moisture, reducing the risk of mold, mildew, and deterioration due to water ingress.

Types of Concrete Sealers

Choosing the right type of sealer is crucial for achieving the desired benefits. The main categories include:

  • Acrylic Sealers: These are great for enhancing color and providing a protective cover. They are easier to apply and reapply but may require more frequent maintenance.
  • Epoxy or Urethane Sealers: Highly durable and offer excellent protection against chemicals and abrasion. Ideal for warehouses and industrial areas.
  • Penetrating Sealers: These sealers penetrate the surface of the concrete to form a chemical barrier that protects against moisture and deicing chemicals, making them ideal for exterior applications.

Application and Maintenance

Sealing commercial concrete is not just about choosing the right product; it’s also about proper application and maintenance. Here are a few tips:

  • Surface Preparation: Ensure the concrete surface is clean and free of any existing sealers, oils, or debris. This may involve professional cleaning or treatment.
  • Professional Application: For best results, particularly in commercial settings, consider hiring a professional. Companies like Elite Concrete Lincoln NE specialize in commercial concrete services and can ensure a high-quality finish.
  • Regular Reapplication: Depending on the type of sealer and the level of traffic, sealers may need to be reapplied every few years to maintain their effectiveness.

Common Questions About Sealing Commercial Concrete

While the benefits of sealing commercial concrete are clear, many property managers and builders have specific questions about its application and effectiveness.


  1. How often should commercial concrete be resealed?
  • Typically, commercial concrete should be resealed every 2 to 5 years, depending on the type of sealer used and the amount of traffic and exposure to harsh conditions.
  1. Can sealing extend the lifespan of outdoor concrete surfaces?
  • Yes, sealing can significantly extend the life of outdoor concrete by protecting it from weather extremes, moisture, and chemical corrosion.
  1. Is it cost-effective to seal commercial concrete?
  • While the initial cost of sealing can be significant, the long-term savings in reduced maintenance, cleaning, and repair costs make it a cost-effective choice for most commercial properties.

Sealing commercial concrete is highly beneficial, particularly in high-traffic and exposed environments. It enhances the durability, appearance, and longevity of concrete surfaces, making it a wise investment for any commercial property.
