I have a small sidewalk I am working on. The other sidewalks have the pea gravel & concrete look formed by washing off the concrete before it sets. How do I know and when is the right time to wash off the top layer of concrete to expose the mixed-in pea gravel? I was told to wait an hour afterwards. Use a garden hose and broad broom to lightly remove the concretre. Any other suggestions? Some have suggested a concrete retardent, but I could not find any at Home Depot! Some have suggested a concrete supplier, but said that they carry it in a 5 gal bucket. Others said that it is not necessary for a small patch. Any other things I should know??
