Angie Posted September 7, 2013 Share Posted September 7, 2013 We recently laid a strip of concrete, it looks fine and is nice and smooth. However, after it gets wet and when we sweep it there seems to be a thin layer of sand on top as though its finding it's way to the surface or is drying out on top. As we are now going to tackle a larger area can anyone advise on this as we don't want it happening again? Do we need to use more cement. Thanks in advance for any suggestions.
