Concrete surfaces are subject to wear and tear over time. Resurfacing is a cost-effective method to revitalize and restore these surfaces, extending their lifespan and improving their appearance. In this article, we will explore the best practices for concrete resurfacing to ensure a durable and visually appealing result.

Assessing the Condition of the Concrete

Before considering concrete resurfacing as a solution, it is crucial to thoroughly assess the condition of the existing concrete surface. This assessment involves inspecting for any damage, cracks, or underlying issues that may affect the suitability of resurfacing. Additionally, inspecting the concrete's structural integrity and stability is essential. Let's dive deeper into these assessment factors:

Inspecting for Damage, Cracks, and Underlying Issues:

  • Surface Damage: Evaluate the surface of the concrete for any visible damage, such as scaling, spalling, or pitting. These issues may be the result of weather exposure, freeze-thaw cycles, or general wear and tear. Resurfacing can help address and improve the appearance of minor surface damage.
  • Cracks: Identify any cracks on the concrete surface and determine their severity. Hairline cracks are typically superficial and can be easily addressed with resurfacing. However, larger and more significant cracks may require additional repair measures before resurfacing can be applied successfully.

  • Underlying Issues: Assess if there are any underlying issues affecting the concrete, such as moisture intrusion, unstable subbase, or structural problems. These issues may need to be addressed before resurfacing can be considered. Failure to identify and rectify underlying issues can result in resurfacing failure and further deterioration of the concrete.

Suitability of Concrete Resurfacing:

Based on the extent of damage and underlying issues identified during the assessment, determine if concrete resurfacing is a suitable solution. Factors to consider include:

  • Superficial Damage: For minor surface damage, such as small cracks, shallow pitting, or surface discoloration, resurfacing can be an effective solution. The new layer of concrete will provide a fresh and even surface, improving the appearance and functionality of the concrete.
  • Structural Stability: Concrete resurfacing is not a solution for structurally compromised or unstable concrete. If the assessment reveals significant structural issues, such as deep cracks, extensive spalling, or shifting concrete slabs, it may be necessary to address these problems before considering resurfacing.
  • Underlying Issues: If your inspection uncovers underlying issues, such as water infiltration or an unstable subbase, these issues should be resolved before resurfacing. Failing to address these problems can lead to resurfacing failure and further deterioration of the concrete.

Thoroughly inspecting the condition of the existing concrete for damage, and evaluating the concrete's structural integrity and stability, you can make an informed decision on whether or not resurfacing is an appropriate solution. It is important to address any underlying issues and ensure that the concrete is structurally sound prior to resurfacing to achieve successful and long-lasting results. If in doubt, consult with professionals who can provide expert advice and assistance in assessing and addressing your concrete’s condition and recommending suitable solutions.

Preparing Your Concrete Surface

Proper surface preparation is a critical step in achieving a successful and long-lasting concrete resurface. We will focus on three essential aspects of surface preparation: cleaning the concrete surface, repairing existing damage, and addressing underlying issues.

Cleaning the Concrete Surface:

Before resurfacing, it is important to thoroughly clean the concrete to remove dirt, oil, and debris. Cleaning ensures that the resurfacing material adheres well to the existing concrete. Here are some recommended steps for cleaning:

  • Remove Loose Debris: Start by removing any loose debris, such as leaves, dirt, or gravel, using a broom or leaf blower.
  • Power Washing: Use a power washer to remove stubborn dirt, stains, or oil from the surface. Use a suitable cleaning solution or detergent designed for concrete surfaces, following the manufacturer's instructions. Thoroughly rinse the concrete surface after cleaning.
  • Removing Efflorescence: Efflorescence is the white powdery residue that sometimes appears on concrete surfaces due to water and salt migration. To remove efflorescence, scrub the surface with a stiff brush and a mixture of water and white vinegar or a commercial efflorescence cleaner. Rinse thoroughly after cleaning.

Repairing Cracks, Chips, or Spalling:

Before resurfacing, it is essential to repair any existing cracks, chips, or spalling on the concrete surface. Ignoring these issues can lead to further deterioration and compromise the resurfacing project. The repair process typically involves the following steps:

  • Cleaning and Preparing the Damaged Area: Clean the damaged area by removing loose debris, dirt, and any deteriorated concrete. Use a wire brush or a chisel to create clean edges along the crack or chip.
  • Filling the Cracks or Chips: Use a suitable concrete patching compound or specialized crack filler such as caulk or epoxy to fill in the cracks or chips. Follow the manufacturer's instructions for proper application and curing time.

  • Smoothing and Leveling: After applying the patching compound, use a trowel or putty knife to smooth and level the repaired surface. Ensure that the repaired area matches the surrounding concrete. In some cases, you may need to lightly grind down the compound once it has cured.

Addressing Underlying Issues:

As part of your surface preparation, any underlying issues that may affect the success of the resurfacing project should be addressed. Here are two common underlying issues to consider:

  • Moisture Problems: Moisture can compromise the adhesion and durability of the resurfacing material. If there are signs of moisture-related issues, such as water stains or efflorescence, it is important to identify and address the source of moisture before resurfacing. This may involve improving drainage or addressing water leakage issues.
  • Settlement or Subbase Problems: Uneven concrete slabs and unstable subbases can cause resurfacing materials to crack or fail prematurely. If the concrete surface shows signs of significant unevenness or if the subbase is unstable, it may be necessary to address these issues before proceeding with resurfacing. This may involve leveling the surface or having the subbase stabilized. We recommend speaking with a professional before taking on stabilization and leveling projects.

By thoroughly cleaning the concrete, repairing existing damage, and addressing underlying issues such as moisture problems or unevenness, the surface will be properly prepared for the resurfacing process. Depending on the product you choose, a light grinding, or acid wash of your concrete may be required prior to installation.
