Concrete resurfacing can breathe new life into your floors, patios, driveways, and other concrete areas, but with so many options available, it can be challenging to know where to start. 

The best materials to resurface concrete include acrylic overlays, epoxy coatings, cementitious resurfacers, decorative overlays, and polyurethane toppings.

What are the Best Materials to Resurface Concrete? 

The best materials to resurface concrete include: 

1. Acrylic-Based Concrete Overlays

Acrylic-based concrete overlays are composed of acrylic polymers that are applied as a thin coating, typically ranging from 1/8 to 1/4 inch in thickness.

These materials offer several key advantages, including flexibility, a wide range of color options, and relatively quick curing times. This makes them well-suited for residential and light commercial applications, such as patios, walkways, and garage floors, where a decorative and durable surface is desired. 

2. Epoxy-Based Concrete Coatings

Epoxy-based concrete coatings are another popular choice for resurfacing concrete surfaces, particularly in industrial and commercial environments. These two-part, chemically-curing resin systems provide an exceptionally durable and seamless finish that is highly resistant to chemicals, abrasion, and other forms of wear and tear. 

The seamless nature of epoxy coatings helps to prevent the ingress of moisture, contaminants, and other substances, making them ideal for use in areas like warehouses, factories, and commercial kitchens where the concrete surface may be exposed to various spills or heavy foot/vehicle traffic. The chemical and abrasion resistance of epoxy coatings also makes them a popular choice for high-traffic commercial and industrial settings, where the concrete surface needs to withstand significant wear and tear over time.

3. Cementitious Concrete Resurfacers

Cementitious concrete resurfacers are a cost-effective option for resurfacing and repairing existing concrete surfaces. These cement-based materials can be used to create a new, durable surface over the top of the existing concrete, with the ability to add texture, patterns, and even color to the finished product.

Cementitious resurfacers are highly durable and can be used in both interior and exterior applications, making them suitable for a wide range of concrete surfaces, including driveways, sidewalks, and basement floors. 

4. Polyurethane Concrete Toppings

Polyurethane concrete toppings are a specialized resurfacing option that offers superior flexibility and impact resistance compared to other concrete coatings and overlays. These materials are typically applied as a thin topping, ranging from 1/8 to 1/4 inch in thickness, and are well-suited for high-traffic areas such as warehouses, manufacturing facilities, and commercial spaces. 

The flexible nature of polyurethane toppings allows them to better accommodate minor movements or impacts in the underlying concrete, reducing the risk of cracking or delamination over time. This makes polyurethane toppings an excellent choice for areas that experience heavy foot traffic, the movement of heavy machinery, or other sources of impact and stress on the concrete surface.

5. Decorative Concrete Overlays

Decorative concrete overlays offer a unique way to transform the appearance of existing concrete surfaces while also providing a durable and long-lasting finish. These overlays can take many forms, including stamped, stained, and textured finishes, allowing homeowners and designers to customize the look and feel of the concrete to their desired aesthetic. 

Stamped overlays can replicate the appearance of materials like brick, stone, or tile, while stained overlays can create a range of translucent color effects. Textured overlays, on the other hand, can add a unique tactile quality to the surface, enhancing both the visual and functional aspects of the concrete. 

When selecting a decorative concrete overlay, it’s important to consider the intended use of the space and ensure that the chosen finish is durable enough to withstand the expected level of foot traffic or other use without excessive wear or damage over time.

What are the Key Factors to Consider When Selecting Resurfacing Materials?

When selecting the best materials to resurface your concrete, here are the top 7 factors to consider:

1. Durability and Long-Term Performance

The resurfacing material you choose should be able to withstand the expected foot traffic, weather conditions, and other environmental stresses your concrete will face over time. You want a solution that will maintain its integrity and appearance for years to come.

2. Slip Resistance and Safety

In high-traffic areas or anywhere people will be walking, it’s important to select a resurfacing material that provides adequate slip resistance to prevent accidents and ensure the safety of those using the surface.

3. Aesthetic Appearance and Customization

The visual appeal of the resurfaced concrete is often a top priority. Look for materials that offer a wide range of color options, textures, and patterns to achieve the desired aesthetic.

4. Environmental Factors

Depending on your location and climate, you may need to consider factors like UV resistance, chemical resistance, and temperature tolerance when choosing a resurfacing material.

5. Application and Curing Requirements

Different products may have specialized application techniques, such as spraying or troweling, and require specific equipment. Equally important is the curing time, which can range from hours to weeks, during which the surface must remain undisturbed to allow the material to fully harden and develop its intended strength and durability. 

6. Surface Preparation Needs

The required surface preparation is a crucial factor that can significantly impact the success of your concrete resurfacing project. Thoroughly understanding the recommended methods, such as grinding, etching, or priming, is essential to ensure proper adhesion and long-term performance. 

Allocate sufficient time and resources for the necessary surface preparation, as improper preparation can lead to premature failure of the resurfacing system.

7. Maintenance and Upkeep

The ongoing maintenance and upkeep requirements of the resurfacing material are essential considerations. Evaluate the frequency and complexity of tasks such as resealing, recoating, or specialized cleaning to ensure the resurfaced concrete maintains its appearance and performance over time. Factor in the availability and cost of any specialized maintenance products or equipment needed.

Should I Consult Professionals for Best Resurfacing Concrete Material Selection?

Yes, it is generally recommended to work with professional contractors or experts when choosing the best material for resurfacing concrete. Here are 5 reasons working with professionals can be advantageous:

  • Expertise in evaluating existing concrete conditions and recommending the most suitable resurfacing material
  • Extensive knowledge of the various resurfacing options, their strengths, limitations, and appropriate applications
  • Proper installation techniques to ensure the long-term durability and performance of the new surface
  • Ability to provide warranties or guarantees on the workmanship and materials, offering added peace of mind
  • Access to high-quality, specialized resurfacing products and equipment that may not be readily available to DIY homeowners

How long does the installation process take for different resurfacing options? 

The installation time for different concrete resurfacing options can vary significantly, depending on the specific material and the complexity of the project. Generally, acrylic-based overlays and polymer-modified cementitious toppings can be installed relatively quickly, often within a single day or two. 

Epoxy coatings typically require a longer curing time, with the installation process taking anywhere from 1 to 3 days. Decorative concrete resurfacing, such as stamped or stained overlays, may require additional time for the intricate installation and finishing work, potentially taking 2 to 4 days to complete.

How do I ensure proper adhesion between the resurfacing material and the existing concrete?

To ensure proper adhesion between the resurfacing material and the existing concrete, it’s important to properly prepare the concrete surface before application. This involves mechanically abrading or profiling the concrete, either through grinding, shot blasting or scarifying, to create a rough, open-pore surface that allows the resurfacing material to mechanically bond. 

Also, any contaminants, such as dirt, oil, or previous coatings, must be thoroughly removed to provide a clean, receptive substrate.

Do I need to prepare the existing concrete surface before applying a new overlay?

Yes, it is essential to properly prepare the existing concrete surface before applying a new overlay or resurfacing material. Skipping surface preparation leads to delamination, premature failure, and other issues with the new concrete overlay.

What is the lifespan of different concrete resurfacing materials? 

As a general guideline, acrylic-based overlays and polymer-modified cementitious toppings tend to have a lifespan of around 5 to 10 years with proper care, while epoxy coatings and polyurethane concrete systems can often last 10 to 15 years or longer in well-maintained, low-to-moderate traffic areas.

Decorative concrete overlays, such as stamped or stained systems, may have a slightly shorter lifespan of 7 to 12 years, as the aesthetic elements are more susceptible to wear and weathering over time. It’s important to note that these are approximate ranges, and the actual longevity of a concrete resurfacing material can be influenced by a variety of site-specific conditions.
