What happens here

The final and most crucial step is to clean the entire floor thoroughly with a power washer, using a rotating nozzle. This process aims to remove all the fine, silty concrete dust that is generated during the acid etching. If this fine concrete dust is not completely removed from the pores of the concrete, it can create an adhesion problem for the epoxy coating. Therefore, it's essential to take your time and ensure all loose residue is meticulously power washed away.

Goal: Thoroughly clean the etched concrete floor to remove all fine concrete dust, ensuring optimal epoxy adhesion.

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.
