Hardware Store Epoxy?

[Guest]

Small weigh scales can also be used to measure out the right amounts of epoxy and hardener if they are runny and difficult to estimate volumes with... with the caveat that the mix-by-weight proportion may be slightly different than the mix-by-volume.

I can see the ease of weighing epoxy if making larger pots, glassing a canoe or some such. For most of my regular epoxy needs calibrated pumps work perfectly. At the least I’m using a single pump each of hardener and resin. 0.8 fl oz total. More often a couple or three pumps per batch.

For making pea or bean sized amounts of G/flex weighing it seems unlikely with the small-weight scale I have, and even the graduated medicine cups won’t help much. I just try to eyeball a drip drip, drip drip of each and mix.

And even then too often make more than needed for little household repairs. Like using up the 105/206 pot dregs and wet roller/brush I try to have something on stand-by that needs a little smear of G/flex.

I may still make too much tiny amount G/flex - needed a pea, mixed a bean - but I have gotten dang good at estimating the amount of 105/206 needed for any particular job. I made two batches of epoxy recently for a skid plate, 105/205 & pigment, a top coat of 50/50 G/flex and 105/206 with pigment and graphite powder.

There wasn’t enough leftover in the pot or on the brush from either batch to bother wiping off somewhere.

That’s a good feeling.
