Muriatic Acid Concrete Removal

How to determine what type of concrete sealer was used.

Muriatic acid concrete removal.

You can also use acid in weaker concentrations to remove white mineral deposits efflorescence and heavy grime. If you need a stronger solution mix 1 part acid to 10 parts water. A four to one mix of water and muriatic acid will interact with the lime in concrete generating bubbles or fizzing if the surface is bare. Grind the floors with an orbital sander to remove etching.

Muriatic acid must be diluted with water before use. Washing brick concrete or stone with muriatic acid can neutralize alkalinity allowing paint finishes to last for years. The easiest dilution to remember is 1 cup of acid to 1 gallon of water. You should see a chemical reaction as soon as you apply the muriatic acid.

Leave it in place for 20 minutes. Chemical paint stripper will not remove the etching. You have some variety of choice when it comes to which products you want to use. The solution begins to bubble and it lifts and removes the stain.
