okay have another question I was using some epoxy to fill some cracks on some Sawmill cutoffs turning them into charcuterie boards and the latest round of epoxy didn’t come with metering pumps so while I balling I must have been a little light on resin because it’s not setting up the first poor setup fine second for seems to be light on resin it’s been 48 hours and still really gooey is there a way to get this set or does it need to be start it over

At this point, I’d call a mulligan and remove the epoxy. You can see a good way to do it from West System.

Try heating it up… either with something like a hair dryer, or if it’s small enough, in the oven for a while.

Cheers,

With epoxy ratio is important. It is not a catalyst reaction. Both parts are consumed at a specific ratio. If there is too much of either there will be ions of that component left in the material after all the available crosslinking has been done. These free ions will adversely effect the properties of the compound.
Yes, it’s too late. Remove the muck and measure more carefully.
Also be aware that when the material is cold and there are viscosity differences between the components pumps can be less that accurate.

I mix my epoxy by weight. With T88, it is a ratio of 100 resin to 83 hardener. I just never trusted the pump things.

This is a great suggestion. I don’t ever do it, which is probably why my epoxy mixes and baked goods equally turn out poorly :p

Thank you all. It also looks like the sent me the wrong mixing ratios I found out when I contacted the supplier about where my pumps where at ( I know close at best) think I’m going to hit harbor freight today for a scale

If you are mixing by weight, make certain you know the weight ratio which can be different than a volume ratio.
