Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums General Petroliana Discussion Effect of full strength muriatic acid on concrete

About a month ago my very nice driveway started showing odd spots and strips of what looks like what an acid might do. There has been some vandilism in the area, and I am wondering if this new appearance on the driveway could be from acid? The spots and other discoloration are a tan color.Any help would be greatly appreciated.

Acid is pretty easy to tell, the acid will eat the top layer off the concrete. This will expose the sand in the concrete. It looks like it was worn away in spots. If the "cream" is still on the top, it was not acid.
Being in the swimming pool industry for 12 year, I have seen this too many times. I usually see it in pictures, with a letter from a lawyer telling me one of the guys that works for me ruined something... glad to be out of that business

I TRIED MURATIC ACID TO REMOVE A CYLINDER ONCE, GOT SOME ON MY GARAGE FLOOR, IT DIDN'T STAIN, IT ATE AWAY THIN COAT OFF THE TOP OF THE CONCRETE.

Hi Guys..interesting thread but am gonna move it to the non petro section ...it can discussed there more if anyone has thoughts
