When discussing concrete and its many properties, it is important to note that “acid wash” can mean different things to different people.
It is important to note that acid washing can also have other effects on concrete, such as changing its texture or increasing its porosity.
As such, it is important to be aware of all the potential effects of acid washing before undertaking any such project.
Acid washes a concrete surface to lessen the color of the stain. The procedure of removing the top layer of a concrete surface in order to expose its pores and offer a clean slate for a coating is known as acid washing.

How Do You Acid Wash A Concrete Patio?
A smooth, shining surface on a concrete patio may make it slick when wet or prevent paint or sealer from sticking.
Acid washing erodes the top layer of cement, revealing more sand in the concrete mixture and roughening the surface. Acid washing is also effective in removing tough stains.
Several acids for concrete etching are available at home improvement stores, including citric, sulfamic, phosphoric, and muriatic.
Choose the safest one that will accomplish the job. Citric acid may not be powerful enough for a slippery patio, but the strongest acid, muriatic, necessitates extreme caution.
Step 1
Sweep the patio to get rid of any loose dirt. Choose a day with no wind to work on. Make a solution of 1 gallon of water and 1 tablespoon of salt. Of detergent and scrub the patio to remove any remaining dirt, grease, or oils. Using a hose, thoroughly rinse away the soapy water.
Step 2
Put on old clothing, rubber boots, rubber gloves, and goggles. 1 gallon of water per 60 to 75 square feet of patio in a watering can or acid-safe sprayer.
Follow the package guidelines for the strength of the solution when adding the acid to the water—a typical concentration may be 10% muriatic or 50% phosphoric acid.
Step 3
While the patio is still moist after cleaning, spray or sprinkle the acid solution over it. Using a stiff-bristled brush, scrub the solution into the surface. Wait 10 minutes or until the bubbling has stopped. Weaker acids may require more time.
Step 4
In a bucket, combine 1 gallon of water and 1 package of baking soda. Spread it with a brush to neutralize the acid, then thoroughly rinse the patio with clean water from a hose and allow it to dry.
Step 5
Check the patio surface with a dark cloth for lingering light-colored powdery residue. If powder remains on the towel, rinse the patio until it is clean.
