Asking because while I see that paint hardeners exist in the USA, there doesn’t seem to be anything similar in my country (Brazil)
What could I use as a substitute to harden paints? Are there any catalysts or powders that would work?
Google and DDG always show sites/articles about epoxy resins whenever I search for “acrylic hardener”, is it safe to assume that catalysts for epoxy, like polyamide, will work with acrylics?
Cat litter should work as well for acrylic paint as it does for latex paint.
