How to patch architectural concrete

In the world of commercial properties, architectural concrete stands out because of it’s  durability and aesthetic appeal. Over time, however, even the most well-maintained concrete can develop issues, such as cracks, spalling, or discoloration. Addressing these issues promptly ensures the longevity and beauty of your building. 

At JKI Industries, Inc., we pride ourselves on our masonry and concrete restoration expertise. Below, we’ll guide you through the essential steps to patch architectural concrete, ensuring your property remains clean, safe, and beautiful. 

Inspect and assess

Before diving into the repair process, thoroughly inspect the surface. Identify the cause of damage, whether it’s due to water ingress, structural issues, or environmental factors. For example, if there is a leak, you’ll need to address that before repairing the issue, or it will just get damaged all over again. Pinpointing the root cause helps determine the best repair method and prevents recurring problems.

Clean the area

The concrete surface should be free from dirt, grease, or any loose materials for a successful patch. If you patch a dirty section, that debris stays in the patch forever.

Choose the right patch

Numerous patching compounds are available, each tailored for specific types of damage. For minor cracks, a simple concrete filler will suffice. For larger gaps or surface-level damage, an epoxy-based or polymer-modified concrete patch is more suitable. Always refer to the manufacturer’s guidelines to ensure the best results.

Apply the Patching Compound

Once you have your patching compound ready, fill the damaged areas. For deeper cracks or holes, it may be necessary to fill in layers, allowing each to dry before adding the next. Smooth the surface with a trowel to ensure the patch aligns with the surrounding concrete.

Cure the Patch

Allow the patch to cure as per the compound’s guidelines, which can range from a few hours to several days. This step is crucial to achieving a bond as strong as the original concrete.

Seal and Protect

After patching, it’s essential to prevent future damage. At JKI Industries, we recommend our commercial waterproofing to seal the area, preventing water penetration. Our range of commercial paint and coatings can further protect the patched area from environmental factors, ensuring it blends seamlessly with the original surface. 

Architectural concrete is a great investment for commercial properties. But, it is a significant investment, and regular maintenance ensures its longevity and aesthetic value. While patching might seem daunting, you can restore your property to its original glory with the right tools, materials, and expertise.
