Will muriatic acid eat through concrete?

The acid works well on concrete and on many masonry projects because it neutralizes alkalinity. The surface becomes “etched” and clean, which allows for the proper adhesion of a new coating. Despite its effectiveness, muriatic acid should be used on concrete stains only if you've tried gentler alternatives to no avail.

Will muriatic acid weaken concrete?

How do you chemically destroy concrete?

Sulfuric acid is the most severe type of acid which causes both dissolution of the calcium hydroxide as well as sulfate attached (due to the presence of sulfate ions). Any solution to prevent penetration of aggressive materials into the concrete can reduce the likelihood of acid attack.

Can I clean my driveway with muriatic acid?
