Acid Etch a Concrete Surface Update
How To Acid Etch Concrete Floor
Important Note: Always take precautions when planning acid etching on your concrete floor! Improper use could cause damage to both the surface and your body.
When etching a concrete garage or floor, it is best not to use aggressive acids like Hydrochloric or Muriatic acid, but a milder concentrated acid solution that produces a light etch. These concentrated solutions typically use a mild acid (phosphoric) to lightly etch the surface of your new epoxy coating. Using a milder acid instead of muriatic acid gently increases the porosity of the surface without damaging the substrate, thereby allowing better adhesion of the Epoxy Coating.
Using a Milder Acid For Etching Advantages:
- Concentrated
- There is less chance of damage to skin, body, and concrete surface
- Easier to use
- Better penetration/adhesion for your new coating
