What happens here

After the initial rinsing, perform a thorough power wash of the entire garage floor. Utilize a power washer equipped with a rotating nozzle for maximum effectiveness. This step is extremely important because acid etching creates a lot of fine, silty concrete dust. If this concrete dust is not completely power washed out of the pores of the concrete, it will cause a significant adhesion problem when applying the epoxy. Take your time to meticulously clean the entire surface, ensuring all loose residue is removed.

Goal: Remove all fine silty concrete dust from the etched floor to ensure proper epoxy adhesion.

Tools and materials

  • Power Washer — Thoroughly cleaning the etched concrete floor

important. Heat. Heat. The floor has been now power washed really good with a rotating nozzle. You want to make sure you power wash it extremely well with a rotating nozzle. As when you're acid etching it, it creates a lot of fine, silty concrete dust. And that concrete dust, if it's not power washed out of the pores of the concrete, will cause an adhesion problem with the epoxy adhering to the concrete. So you got to make sure you take your time and power wash it extreme.
