I plan to do a concrete sidewalk in front of my home. My problem is the large number of kids that walk past my house to and from school each day. They may find new concrete too tempting. If a footprint or mark gets put in my concrete can it be fixed?
Yes up to a point. Before you start your new sidewalk get a small amount of sand topping mix. You can use it to make repairs if needed. Should you find marks on your newly finished sidewalk and the concrete surface hasn’t hardened beyond the point of repair, mix some of the sand topping mixes and float it into the marked spots and a little bit wider area around those marks. Put a little bit of water on the surface as you apply the mix to the damaged areas. The water will help in working the new mix into the existing finish. Wait a few minutes and retrowel. And then rebroom. This isn’t foolproof, but it usually will work if the concrete from the initial pour hasn’t been completely set up.
