How to Fix Honeycomb in Concrete

When it comes to home improvement projects like how to fix honeycomb in concrete, nothing is more frustrating than taking on a job only to run into unexpected issues along the way. Just last month, I finally decided to tackle a project I had been putting off for years – refinishing my garage floor. Peeling up the old flaking concrete, I was dismayed to discover it was riddled with honeycombing underneath. What looked like a simple resurfacing job suddenly seemed much bigger.

How to Fix Honeycomb in Concrete

I had never dealt with honeycombing before and wasn’t sure where to even start to fix it. After several failed attempts at patching and hours of research, I finally developed a process that actually worked. Now I want to share what I learned in the hopes of saving you time, money and headaches should you ever encounter this concrete conundrum yourself.

Advantages of Fixing Honeycomb in Concrete

Before jumping into the repair process, it’s important to understand why fixing honeycomb in concrete is necessary. Honeycombing occurs when pockets of air or voids are left in the concrete after pouring and curing. This can happen for a variety of reasons such as improper mix ratios, poor consolidation techniques, or inadequate vibrating during placement.

Regardless of the cause, honeycombing weakens the structural integrity of the concrete and can lead to further damage if left untreated. By fixing a honeycomb in concrete, you not only improve its appearance but also prevent potential safety hazards.

Materials Needed for Repair

To successfully fix honeycombing in concrete, you will need the following materials:

  • Concrete Patching Compound
  • Concrete Bonding Adhesive
  • Scraper or Chisel
  • Wire Brush
  • Bucket for Mixing
  • Trowel or Putty Knife
  • Safety Gear (gloves, goggles, etc.)

11 Step-by-step Guidelines on How to Fix Honeycomb in Concrete

Step 1: Identify the Affected Areas

The first step in fixing honeycomb in concrete is to identify the areas that need repair. Carefully inspect the surface of your concrete for any visible voids, air pockets or exposed aggregate. It’s essential to address all honeycombed areas as even small pockets can compromise the integrity of your repair. You may also want to mark the affected areas with chalk or tape for easier reference during the repair process.

Step 2: Prepare the Surface

Before beginning any repairs, you must thoroughly clean and prep the concrete surface. Use a scrape or chisel to remove any loose debris, dust, and residue from the honeycomb areas. Then, use a wire brush to remove any remaining particles and ensure a clean surface for bonding. It’s crucial to remove as much loose material as possible, or the patching compound may not adhere correctly.

Step 3: Mix Concrete Patching Compound

Follow the manufacturer’s instructions to mix your concrete patching compound. Generally, this involves adding water to the powder and mixing until you achieve a smooth, thick consistency. Make sure to mix only enough material that you can use within the working time specified on the product packaging.

Step 4: Apply Bonding Adhesive

Before applying the patching compound, it’s essential to apply a bonding adhesive to ensure proper adhesion between the existing concrete and the patch. Follow the manufacturer’s instructions to apply the bonding adhesive with a paintbrush or roller, covering all of the affected areas. But be sure to work quickly as the adhesive dries fast.

Step 5: Fill in Honeycombed Areas

Using your trowel or putty knife, start filling in the honeycombed areas with your prepared patching compound. Press firmly to ensure proper adhesion and eliminate any voids or air pockets. If the area is deep, you may need to fill it in layers, allowing each layer to dry before adding more. You can also use a wire brush to blend the edges of the patch with the surrounding concrete for a smoother finish.

Using Your Trowel or Putty Knife

Step 6: Smooth out the Surface

Once you’ve filled all of the honeycombed areas, use your trowel or putty knife to smooth out the surface of the patch. This will help create a flush and level repair that blends in with the original concrete. It’s okay if the surface is slightly textured, as long as it is level and even. Although, you can also use a float or sponge to create a smoother finish if desired.

Step 7: Wait for Curing

Allow the patch to cure for at least 24 hours before walking or driving on it. However, curing times may vary depending on the product used, so be sure to check the instructions for specific guidelines. It’s crucial to give the patch enough time to fully set before putting it under any stress.

If possible, try to avoid any heavy traffic or heavy loads on the patched area for at least a week. You may also want to cover the repaired area with plastic or a tarp to protect it from any elements that may disrupt the curing process.

Step 8: Sand the Surface

After curing, sand down any rough or uneven areas using a coarse-grit sandpaper. This will help create a smoother surface and remove any imperfections in the patch. You can also use a grinder or sander for larger areas, but be careful not to damage the surrounding concrete. It’s best to start with a coarse grit and gradually work your way up to a finer grit for the smoothest finish. It’s best to start with a coarse grit and gradually work your way up to  a finer grit for the smoothest finish.

Step 9: Clean and Rinse

Once you have completed sanding, clean the surface of your patch to remove any dust or debris. You can use a broom or vacuum for this step. Then, rinse the surface with water to remove any remaining residue. It’s essential to have a clean and dry surface before moving on to the next step. But be sure to let the surface dry completely before proceeding. It may take a few hours for the surface to dry completely, depending on weather conditions.

Clean the Surface of Your Patch

Step 10: Apply Sealant (Optional)

You can opt to apply a sealant over your repaired concrete to provide extra protection and prevent further damage. Follow the manufacturer’s instructions to apply the sealant evenly over the patched area. It’s best to choose a sealant that is compatible with the patching compound used. It’s also essential to let the sealant dry completely before using the area. This step is optional, but it can help prolong the life of your repair.

Step 11: Finishing Touches

Finally, after allowing the sealant (if applied) to dry, you can add any finishing touches such as painting or staining to match the rest of your concrete. This step is optional but can help improve the overall appearance of your repair. Make sure to follow any product instructions for proper application and drying times. Otherwise, you have successfully fixed the honeycomb in your concrete!

Following these step-by-step guidelines on how to fix honeycomb in concrete will help you effectively repair the honeycomb in concrete and restore its structural integrity. Remember to always wear safety gear, work quickly but carefully, and allow proper curing time for the best results.
