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??
