How to Correctly Fill Cracks in Concrete?

To correctly fill cracks in concrete, you will need to follow these steps:

1. Clean the crack: Use a wire brush or a chisel to remove any loose debris or concrete pieces from the crack. You can also use a pressure washer to clean the crack thoroughly.
2. Apply concrete filler: Choose a concrete filler that is suitable for your crack size and depth. Follow the manufacturer’s instructions for mixing the filler and applying it to the crack. Some fillers require a primer or bonding agent to be applied before the filler.
3. Smooth the filler: Use a trowel or putty knife to smooth the filler and make sure it is level with the surrounding concrete surface.
4. Let it dry: Allow the filler to dry completely according to the manufacturer’s instructions. This may take several hours or even a few days depending on the filler used and the weather conditions.
5. Seal the crack: Once the filler is dry, you can apply a concrete sealer to the entire surface of the concrete to prevent moisture from entering the crack.

It’s important to note that if the crack is large or if you suspect that it may be caused by structural issues, it’s best to consult with a professional before attempting to fill the crack yourself.
