We just had 7 yards of concrete poured this weekend. We have been advised by the guys that helped us (pros) that we should wait a week or so and then use muriatic acid to wash down the slabs, dry, and then seal up the 'crete with a commercial sealer.(posted 9645 days ago)We also have some old gnasty, gnarly exposed aggregate concrete that was here when we bought the place. It's covered with moss, and dirt and duck "products". I was told we could clean up the old mess with same caustic product.
I am concerned about using muriatic acid on the new slabs and old stuff, just because the cautions on it are pretty scary and I have heard warnings about it for a long time. Short of using a wire brush and what? bleach? do you guys have any alternatives?
Any recommendations for sealants?
I have lovely rhododendrons and azaleas around my old walkway (old aggregate) plus with the critters around I am always concerned about chemicals.
Got any alternative ideas for this?
Thank you so much. I appreciate all the good advice I get here, and since I am going to school full time again pretty soon, I want to get going on this.
