What Is Concrete Resurfacing?
Concrete resurfacing involves applying a new layer of material over an existing concrete surface to restore its appearance and functionality. It’s an ideal solution for addressing cosmetic issues like cracks, stains, or surface discoloration. Unlike concrete replacement, resurfacing does not require tearing out and replacing the old concrete, making it a much more affordable option.
According to the Concrete Network, resurfacing can be done using different materials, depending on the needs of the surface. Most commonly, cementitious overlays, epoxy coatings, and polymer-based products are used to achieve the desired finish (Concrete Network).
Types of Concrete Resurfacing Products
There are several types of resurfacing materials, each designed for specific purposes:
- Cement-based overlays: These are the most commonly used materials for concrete resurfacing. They can be applied to create a smooth, even surface that hides imperfections.
- Epoxy coatings: These offer superior durability and are often used for garage floors and high-traffic areas.
- Polymer-based resins: These are often mixed with cement to create strong, flexible surfaces.
- Acrylic resins: These are typically used to create decorative, slip-resistant surfaces for pool decks and driveways.
Can You Resurface Concrete?
Yes, you can resurface concrete, but the condition of the underlying surface plays a crucial role. According to The Spruce, concrete resurfacing is effective for surfaces that are structurally sound but have cosmetic damage such as small cracks, stains, or fading. If the concrete is severely damaged—deep cracks, significant settling, or major structural issues—resurfacing may not be the best solution (The Spruce).
To determine if resurfacing is the right option, professionals usually assess the surface’s integrity. If it passes inspection, a resurfacing layer can be applied to restore its appearance.
Can Concrete Be Resurfaced Multiple Times?
Yes, concrete can be resurfaced multiple times, but there are limitations. Over time, the underlying slab may begin to deteriorate beyond what resurfacing can fix. Each new layer of resurfacing material adds thickness to the surface, but after several applications, the structural integrity of the original concrete may be compromised. Therefore, while concrete can be resurfaced two or three times, it’s important to monitor the condition of the base slab.
Concrete Guy MN explains that resurfacing can extend the life of a concrete surface by covering minor imperfections, but it’s essential to address underlying structural issues when necessary (Concrete Guy MN).
Can a Concrete Driveway Be Resurfaced?
Concrete driveways are one of the most common candidates for resurfacing. If your driveway has developed small cracks or faded color, resurfacing can restore its appearance and provide additional durability.
Resurfacing a concrete driveway is a cost-effective way to restore its functionality and enhance the curb appeal of your home. In fact, many homeowners choose resurfacing instead of replacing an entire driveway due to the significant cost savings.
However, if your driveway has major issues like large, deep cracks or significant structural problems, you may need to repair those before resurfacing, or consider complete replacement.
How to Resurface Concrete: Step-by-Step
Resurfacing concrete is a process that can be done on your own with the right tools and materials, though some homeowners prefer to hire a professional. Below is a detailed step-by-step guide to resurfacing concrete.
Step 1: Clean the Concrete Surface
Cleaning is one of the most crucial steps when resurfacing concrete. Dirt, debris, oil stains, and old sealers can prevent the resurfacer from bonding properly. To clean the surface:
- Power Wash: Use a power washer to remove surface dirt and grime.
- Scrub Stains: For oil or grease stains, use a degreaser and scrub the affected area.
- Remove Old Sealers: If the surface has an old sealer, you may need to use a chemical stripper to remove it.
Step 2: Repair Cracks and Holes
Before applying the resurfacer, it’s essential to repair any cracks or holes in the concrete. Use a concrete patching compound to fill in these imperfections and smooth them out. Allow the patches to dry completely before proceeding to the next step.
Step 3: Apply the Resurfacing Material
Once the surface is clean and repairs are made, it’s time to apply the resurfacing material. Follow the manufacturer’s instructions for mixing the resurfacer (often done with water or a bonding agent). Use a squeegee or trowel to apply a thin layer of the material over the concrete surface, working in sections.
Step 4: Smooth and Texture the Surface
After the resurfacer has been applied, use a broom or trowel to smooth out the surface. If desired, you can create a textured finish by dragging a broom or special tool over the surface. This is particularly important for outdoor surfaces like driveways and patios, where slip resistance is important.
Step 5: Let It Cure
Allow the resurfaced concrete to cure properly. This typically takes around 24 to 48 hours for foot traffic and 7 days for vehicles. Ensure the area is kept clean and dry during the curing process to avoid any imperfections.
Materials Used in Concrete Resurfacing
The materials used in concrete resurfacing can vary based on the type of surface and desired results. Common materials include:
- Cementitious Overlays: Cement-based resurfacing products are often used for basic resurfacing jobs. They provide a smooth, durable surface.
- Epoxy Resins: Epoxy coatings are often used for heavy-duty applications like garage floors and commercial areas due to their durability and resistance to chemicals and stains.
- Polymer-Based Products: These provide a flexible, long-lasting finish that is ideal for surfaces exposed to heavy traffic or extreme weather.
- Acrylic-Based Products: Acrylic resurfacing products are commonly used for decorative purposes, offering a glossy, polished finish.
Each of these materials has its specific uses and benefits, depending on the nature of the surface and the level of traffic.
Benefits of Concrete Resurfacing
Concrete resurfacing offers numerous benefits for both homeowners and businesses:
- Cost-Effective: Resurfacing is a fraction of the cost of replacing concrete. It allows you to restore the functionality and aesthetics of your surface at a much lower price.
- Enhanced Appearance: A resurfaced concrete surface looks brand new, adding beauty and value to your property.
- Quick Process: The resurfacing process can often be completed in a single day, with minimal disruption to your daily routine.

- Eco-Friendly: By resurfacing rather than replacing, you reduce waste and save resources, contributing to a more sustainable solution.
What Are the Alternatives to Concrete Resurfacing?
If resurfacing isn’t an option, there are alternatives, including:
- Concrete Replacement: For severely damaged concrete, replacement may be necessary. This is the most expensive option but ensures long-term durability.
- Polymer-Modified Concrete Overlays: If the concrete is deeply damaged, a polymer-modified overlay can be applied. This is thicker and offers more durability than traditional resurfacing.
