Acid Etch a Concrete Surface Update
Important Note: Always take precautions when you plan on Acid Etching 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 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. 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
- Less chance of damage to skin, body, and concrete surface
- Easier to use
- Better penetration/adhesion for your new coating
