Can acid damage concrete?
Particularly damaging to concrete are acids . The lower the pH of the acid and the longer the concrete is in contact with it, determines how quickly and how damaging the acid is to the concrete. Acids attack concrete by dissolving the cement compounds.

How do you epoxy acid etch concrete?
When etching a concrete garage or floor it is best to not use aggressive acids like Hydrochloric or Muriatic but a milder concentrated acid solution that produces a light etch . These concentrated solutions use a mild acid typically (Phosphoric) to lightly etch the surface for your new Epoxy Coating.
What does hydrochloric acid do to concrete?
Acid etching involves allowing the reaction of a dilute hydrochloric acid solution with the concrete surface, then rinsing off with water. The acid chemically reacts with surface laitance1, dissolving it and allowing it and other water-soluble contaminants to be washed away .
How is hydrochloric acid used on concrete?
To clean and etch concrete, mix one part muriatic acid to 10 parts water. Brush or spray the acid solution on the concrete, wait eight to 10 minutes, then neutralize the acid by spraying the surface with a mixture of one cup of ammonia in one gallon of water.
What happens if you spill battery acid?
What is battery acid? Battery leakage (commonly known as battery acid) is nasty, corrosive stuff – it can burn your skin, contaminate soil, and of course ruin whatever device it has leaked into . For household batteries, this “acid” is actually alkaline – thanks to the potassium hydroxide chemical make-up.
Can you use baking soda to neutralize battery acid?
Baking soda can effectively neutralize the corrosive nature of battery acid and washing your clothes in a solution of baking soda and water can also minimize the damage from a spill.
How do you clean sulfuric acid off a floor?
Acid Spills (hydrochloric or sulfuric acid):
Neutralize spill with sodium bicarbonate/baking soda 2. Wait until bubbling/fizzing has stopped 3. When using a neutralizing spill kit, the kits are buffered and will not have a bubbling action. Be careful not to over-neutralize 4.
Can you use vinegar to etch concrete?
Etching – Vinegar’s ability to dissolve CaCO3 will dull your marble, travertine, concrete and terrazzo surfaces . It may “clean” the surface but it is also dissolving pits into the finish and effectively dulling it.
Does white vinegar clean concrete?
White vinegar and a little scrubbing with a brush is a very effective, eco-friendly way to remove rust stains from concrete —even those that are decades old. Pour the white vinegar directly onto the stain, allow the liquid to penetrate the area for 20 minutes, and scrub with a stiff-bristled brush.

- Zep Heavy-Duty Powdered Concrete Cleaner. ...
- Oil Eater Cleaner Degreaser. ...
- Terminator-HSD Concrete Cleaner. ...
- ACT Eco Friendly Concrete Cleaner.
What does Sulphuric acid do to concrete?
Overall, in the acid degradation process, the temperature of the sulfuric acid solution accelerates the mass loss by loosening the bonds between aggregates and cement paste . This results in aggregate loss and eventually higher depth of corrosion.
Can sulfuric acid eat through concrete?
Sulphuric acid attack on concrete can occur in many ways . Concrete can be subjected to attacks by mineral acids which include sulphuric, nitric, hydrochloric and phospheric acid. When concrete is in contact with such acids, the calcium hydroxide reacts with the acid to form gypsum, which can readily be washed away’.
Can you use sulfuric acid to etch concrete?
Properly mix acid solution.
Acids that can be used to etch the concrete are, muriatic, sulfuric, phosphoric, or citric . The most commonly used are muriatic (hydrochloric-HCL) and phosphoric acids. Use only plastic or acid resistant containers for mixing and applying acid.
Can muriatic acid damage concrete?
While it corrodes almost anything it touches, this is not true of 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.
Should I use muriatic acid to clean concrete?
The most common acids used to clean concrete and bricks are hydrochloric acid (muriatic) or phosphoric acid . For many years it has been the standard cleaning method to prepare concrete for coatings installations, to remove stains of any type from concrete and to remove concrete slurry or efflorescence from bricks.
Can you add baking soda and muriatic acid at the same time?
With a TA of 60 and a pH of 7.6-7.8, your acid additions will be much further apart. Unless you are using an acidic form of chlorine (tricolor) or have very low TA fill water, there is no need to ever add baking soda .
