What is the Mix Ratio?
The mix ratio is 2:1 Resin to Hardener. That ratio stays the same when the hardeners are custom blended (See item 19). When blending hardeners, blend In separate containers with the Resin. Be sure to maintain the 2:1 ratio. Back to top 8. Can I apped up the mix my adding more Hardener – ABSOLUTELY NOT! Adding more hardener throws off the ratio and you will end up with a gooey mess that never cures.
