 How can I get rid of soft sticky spots in my resin if after a day of curing you've noticed some soft sticky spots in your resin? It means either one of two things either the delicate one-to-one balance of the resin and hardener was off Just a little bit or the material just wasn't mixed thoroughly Sometimes people mix in the center and they don't mix the outside So we always recommend scraping the outside of the container and the bottom as you stir to make sure that the entire mixture is a hundred percent mixed and therefore a hundred percent catalyzed To fix the sticky spots you need to scrape away any of that unmixed material And secondly you need to sand down any of the cured parts with 80 grit sandpaper To make sure that there's enough tooth to adhere that second layer on top Now when you mix your second coat make sure that it's well measured well mixed And when you pour that second coat after 24 hours your piece will be as good as new
