Re: I screwed up clear coating wood with epoxy....
These products are formulated to reach the desired physical properties at the ratios recommended by the manufacturer, sometimes the ratio can be adjusted a little, but not a great deal. And without discussing it with a tech rep from the company or being a chemist yourself, you won't know what the effects will be. It may become very brittle and crack, or stay rubbery and somewhat soft and weak, neither of these are desirable. If you didn't mix the first batch well enough you will have areas of too little hardener and areas of too much hardener, with a few that may be just right, so the cure will be uneven. This doesn't mean it "will" fail, only that it will be more likely to.
You can look at it this way. If you have a rope that is rated for a 1000 lb load, but you only need to lift 400 lbs, you could theoretically cut 50% of the strands and it would still lift the load. The rope may not fail at 400 lbs, but it is still much weaker than it would have been. When you mess with the hardener/catalyst ratio outside of what is recommended you really have no idea what the exact consequences will be, but you can count on the physical properties being compromised, possibly to the point of total failure.
Applying a coat of over catalyzed resin over a layer of under catalyzed resin doesn’t really help much. All you have is garbage applied over garbage. Now it is possible that where these two layers meet there is a few micron thick layer of properly cured resin, but it’s sandwiched between the two bad layers, so what do you gain.
You can leave it alone and see what happens, apply another layer of properly mixed resin, or remove what’s there and do it again, this part is up to you.
