In reply to DaVid. Hi David. If the old epoxy can't be scraped up in the corner, sand the surface with 100-grit sandpaper. It will provide the mechanical bond required for the SPGX. Unless you are driving and parking in that spot (hopefully not), the SPGX will adhere just fine long-term.

Helpful article, thank you. What is recommended way to get corners the hand held grinder can’t get. I am removing old epoxy and applying SPGX. Thank you.

In reply to Yonggang Wan. Yes, you can do that. However, we recommend waiting a full 48 hours though before applying the coating. Because the concrete is more porous, it will absorb more water that takes time to evaporate out of the concrete. Dry vacuuming is what's done most of the time. The reason is that water is not introduced which slows up the project.

Shea, after a dry grind, can I still use hose to clear the garage floor and let it dry out for 1 or 2 days? It just feels more effective in cleaning up the debris and dust than a vacuum cleaner. Which one is better?
