As you can see, I attempted patching an old spalling concrete sidewalk with premix concrete patching product. I was very disappointed with the results. The color isn't remotely close to the existing sidewalk and it did not trowel out as smooth as I'd hoped. My question is first, how should I remove the failed patch attempt? And how can I get a better match to the existing?
It doesn't have to be perfect. I thought about mixing actual concrete, patching, and then pushing in sand and pea gravel at the top to try to replicate the texture and color. Would that work?
