Response to muriatic acid and exposed aggregate concrete

http://www.geocities.com/PicketFence/Garden/8784/pics/Rock3.jpg......S heepish: Cut and paste this picture of a rock wall of my cabin. I had a terrible problem with white (lime I think) bleeding and I was told the only way to be rid of it was the acid wash. I also did not want this nasty stuff around so I had to keep washing it off and wire brush the tough spots. The longer It's left alone the harder it is to get off. After 6 months I used Thomson's water sealer for concrete. So far a year later no problems. The new pour You don't mention if it's a wall or a walkway. I don't do anything to my walkways. Maybe somebody else knows more that might help me too.....Kirk
