When sealing a bar top with an epoxy clear coat, it is important to mix the resin and hardener in a one-to-one ratio. If these two components are not mixed properly, the epoxy will not cure completely. As a result, the surface of your project could be left with soft, sticky spots that will never go away. Thankfully, however, there is a way to remove these spots so you don't have to scrap the project and start again.
Step 1
Scrape away any epoxy that is soft and sticky. Use a small paint scraper to remove most of it, and then use a small razor blade to cut off any small pieces that are left. Don't push too hard with the paint scraper. Dents and scrapes in the bar top will be visible through the clear finish.

Step 2
Rub down the spot with denatured alcohol or acetone to remove any remaining epoxy. The denatured alcohol or acetone cleans the surface so that the new resin will adhere to the old epoxy correctly.
Step 3
Mix a small batch of epoxy in a clean bucket, and pour a thin coat over the area you just scraped. Let it sit for 4 hours, but not longer than 10.
Step 4
Mix another batch of epoxy, and pour a thick coat over the entire spot. Make sure the thick coat is level with the existing epoxy, and let it dry for at least 24 hours.
