concrete cracks in walkway and steps
We keep getting cracks in our concrete walkway and steps.First we hired someone who said that applied a resurfacing coating to our walkwayway and steps that would cover the cracks and prevent them from returning (I forget the name of the stuff that he applied ) It looked good the first few weeks but then all the cracks appeared again. After fighting with him (We paid him $600) he reapplied it again over the cracks.--The cracks came back. My husband tried patching them with a vinyl concrete patch and now they are back. Aside from getting new concrete steps and walkways , what can we use to patch these cracks? We have about 4 hairline cracks.
