Keeping concrete in good shape can be tough. One fact is that sealing concrete helps it last longer. This article will show you how to permanently seal concrete, step by step. Let’s get started on protecting your concrete surfaces.
Why is Sealing Concrete Important?
Sealing concrete protects it from moisture and water damage. This process keeps your surfaces looking new and extends their lifespan by preventing stains and discoloration.
Protection against moisture and water damage
Moisture is a significant threat to the integrity of concrete. Over time, water exposure leads to cracks, degradation, and weakened structures. Sealing concrete forms a robust protective barrier that prevents water from penetrating the surface, effectively safeguarding the material against these detrimental effects. This protective coating not only keeps moisture at bay but also shields the concrete from the damaging freeze-thaw cycles that can cause further deterioration.
Extends the life of concrete
Properly sealing concrete significantly enhances its longevity. A reliable sealer acts as a shield against water damage and other environmental factors that can degrade the surface. When moisture seeps into concrete, it can cause cracks and lead to further structural deterioration. Sealed concrete, however, remains resilient to these issues.
Prevents staining and discoloration
Sealing concrete is a highly effective way to prevent staining and discoloration, preserving the material’s aesthetic appeal. Without a protective sealer, concrete is highly porous, absorbing liquids that can cause permanent marks and unsightly stains. By applying a sealer to both new and old concrete, you can maintain a clean, vibrant surface over time.
Different Types of Concrete Sealers
Different types of concrete sealers offer various benefits for your projects. Acrylic sealers provide a glossy finish, while penetrating sealers protect against moisture at the surface level.
Acrylic sealers
Acrylic sealers provide excellent protection for concrete surfaces, forming a thin, durable layer that guards against stains, water damage, and wear. Available in both solvent-based and water-based formulas, these sealers offer versatility to suit various needs. Solvent-based acrylics create a glossy finish that enhances the appearance of the concrete, while water-based versions are easier to clean and environmentally friendly.
Epoxy sealers
Epoxy sealers deliver robust, long-lasting protection for concrete, offering a hard, glossy finish that resists stains, chemical spills, and moisture damage. These sealers bond tightly to the concrete, creating an impermeable layer that enhances the durability of the surface. Epoxy sealers are ideal for high-traffic areas such as garages, warehouses, or industrial settings, where their resistance to wear and tear makes them especially beneficial.
Polyurethane sealers
Polyurethane sealers offer exceptional durability, creating a tough protective layer that prevents moisture infiltration and guards against stains and discoloration. These sealers are versatile, making them suitable for a wide range of applications, including driveways, patios, and other outdoor concrete surfaces. They’re ideal for maintaining concrete surfaces exposed to varying weather conditions.
Penetrating sealers
Penetrating sealers are designed to work deep within the concrete, absorbing into its pores to form a barrier that prevents moisture damage, stains, and discoloration. These sealers provide enduring protection by blocking water from penetrating the surface, making them a popular choice for both new and old concrete.
Steps to Permanently Seal Concrete
To permanently seal concrete, follow a few key steps. Start by cleaning the surface thoroughly to ensure proper adhesion before applying your chosen sealer.
Clean the surface
Begin by removing all dirt, oil, and debris from the surface. You can use a pressure washer or a broom to scrub the area clean. For more stubborn stains, washing with soap and water can help remove oil or grime. Allow the concrete to dry completely before proceeding.
Apply a primer
Make sure to choose a primer that is compatible with your chosen sealer—whether acrylic, epoxy, or another option. Once the primer is applied, let it dry thoroughly before moving forward with the sealing process.
Apply the sealer
Once you’ve chosen the appropriate sealer, it’s time to apply it to your cleaned and primed surface. Use a roller or sprayer to apply the sealer in thin, even layers. Avoid overapplying, as pooling can occur. Be sure to cover all areas, including the edges and corners, to ensure comprehensive protection.
Follow the manufacturer’s guidelines for drying times between coats. Typically, applying two coats enhances the waterproofing and protective qualities of the sealer.
Conclusion
Sealing concrete is essential to preserving its integrity, extending its lifespan, and keeping it looking great. By choosing the right type of sealer—whether acrylic, epoxy, or penetrating—and following proper application steps, you can ensure that your concrete surfaces are well-protected from moisture, stains, and wear.

FAQs
What surfaces can be sealed?
Concrete sealing works on driveways, patios, floors, and other concrete surfaces, both new and old. Masonry sealers are also effective for brick and stone. Sealing protects against moisture and stains.
How often should concrete be sealed?
New concrete should be sealed within 28 days, while old concrete needs sealing every 3-5 years, depending on wear and exposure. Regular checks for fading or chipping can indicate when reapplication is needed.
Can I seal concrete myself or hire a professional?
Concrete sealing can be a DIY project if you’re comfortable with the process, but professionals are ideal for damaged surfaces or when you want expert results. Their experience ensures better protection.
