Buy the 2:1 ratio for a harder finish. Seal off the edges or surfaces that you’re coating with a thin layer of epoxy prior to pouring. Double and triple check your mold for possible leakage, as this product is super thin and could leak out anywhere. Mix well for several minutes and then let the product sit in the bucket for 10 to 15 minutes to let the bubbles release before pouring. Once poured, keep an eye out for leaks and swirl the metallic pigments (if any) every few hours up until 12 hours after pouring.
