Hi Linn,This jumped out at me as my father is a mason. On thing you can due to make the concrete look better is mix a very wet slurry of concrete only using silica sand instead of regular sand. Then after your first concrete is dried you mix the silica sand slurry and paint it on with a brush. It gives an even sandpaper type of finish. I might have to make one for my dad as a gift! Thanks.Ryan
